The Coastal Land Use Plan sets forth goals, objectives, and policies that govern the use of land and water in the coastal zone within the City of Newport Beach and its sphere of influence with the exception of Newport Coast and Banning Ranch. Newport Coast is governed by the previously certified and currently effective Newport Coast Local Coastal Program. Banning Ranch is a Deferred Certification Area (DCA) due to unresolved issues relating to land use and the protection of coastal resources (see Section 2.2.4). 1.2 Organization The Coastal Act contains coastal resources planning and management policies that address public access, recreation, marine environment, land resources, development, and industrial development. The Coastal Land Use Plan addresses these topics under the following chapters: Land Use and Development. This chapter includes policies for topics in Sections 30007, 30212.5, 30213, 30221 - 30223, 30235- 30236, 30250, 30252- 30253, 30255, 30260, 30262, 30600, 30610.5 of the Coastal Act. Public Access and Recreation. This chapter includes policies for topics in Sections 30210 - 30214, 30220 - 30224, 30234, 30234.5, 30244, and 30252 of the Coastal Act. Coastal Resource Protection. This chapter includes policies for topics covered in Sections 30230 - 30233, 30240, 30244, and 30251 of the Coastal Act. Each chapter is divided into sections and subsections. Each section or subsection begins with the identification of the Coastal Act sections that are relevant to Newport Beach, followed by a narrative of the local setting and policy direction adopted by the City to address the requirements of the Coastal Act and a listing of specific policies. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 1 -1 1.3 General Policies The following policies shall be applied to achieve the goals and objectives of the Coastal Act in applying the policies of this Coastal Land Use Plan: 1. The policies of Chapter 3 of the Coastal Act (PRC Sections 30200 - 30263) shall be the guiding policies of the Coastal Land Use Plan. 2. When policies within the Coastal Land Use Plan conflict, such conflicts shall be resolved in a manner which on balance is the most protective of significant coastal resources. 3. Where there are conflicts between the policies set forth in this Coastal Land Use Plan and those set forth in any element of the City's General Plan, zoning, or any other ordinance, the policies of the Coastal Land Use Plan shall take precedence. However, in no case, shall the policies of the Coastal Land Use Plan be interpreted to allow a development to exceed a development limit established by the General Plan or its implementing ordinances. 1.4 The Coastal Act In 1972, the United States Congress passed the Coastal Zone Management Act (Title 16 U.S.C. 1451- 1464). The CZMA declared a national policy "to preserve, protect, develop, and where possible, to restore or enhance, the resources of the Nation's coastal zone for this and succeeding generations." The CZMA sought to encourage and assist States to develop and implement management programs for the use of coastal land and water resources, "giving full consideration to ecological, cultural, historic, and esthetic values as well as the needs for compatible economic development." The Coastal Zone Conservation Act (Proposition 20) was approved by a 55.2 percent vote in 1972. It prohibited development 1,000 yards inland from California's mean high tide without a permit from a regional or state coastal commission. It created a temporary California Coastal Zone Conservation Commission and six regional commissions to develop a statewide plan for coastal protection. The California Coastal Plan was submitted to the Legislature in 1975 and led to the passage of the California Coastal Act in 1976. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 1 -2 • • • • • • • • • • • • I he Coastal Act established the permanent California Coastal Commission. The Coastal Commission's mandate is to protect and enhance the resources of the coastal zone mapped by the Legislature. Coastal Commission membership is composed of twelve voting members, appointed equally by the Governor, the Senate Rules Committee, and the Speaker of the Assembly. Half of the voting commissioners are locally elected officials and half are representatives of the public at large. The Coastal Commission also has four ex officio (non- voting) members representing the Resources Agency the Business, Transportation and Housing Agency, the Trade and Commerce Agency and the State Lands Commission. The Legislature found that "to achieve maximum responsiveness to local conditions, accountability, and public accessibility, it is necessary to rely heavily on local government and local land use planning procedures and enforcement." Therefore, implementation of Coastal Act policies is accomplished primarily through the preparation of a Local Coastal Program (LCP), reviewed and approved by the Coastal Commission. An LCP typically consists of a land use plan and an implementation plan. The land use plan indicates the kinds, location, and intensity of land uses, the applicable resource protection and development policies, and, where necessary, a listing of implementing actions. The implementation plan consists of the zoning ordinances, zoning district maps, and other legal instruments necessary to implement the land use plan. Any amendments to the certified LCP will require review and approval by the Coastal Commission prior to becoming effective. After certification of an LCP, coastal development permit authority is delegated to the appropriate local government. The Coastal Commission retains original permit jurisdiction over certain specified lands, such as submerged lands, tidelands, and public trust lands, and has appellate authority over development approved by local government in specified geographic areas. In authorizing coastal development permits, the local government must make the finding that the development conforms to the certified LCP. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 1 -3 1.5 The City of Newport Beach History In order to fully understand the relationship between the Coastal Land Use Plan and the community, it is necessary to understand the community and the historical events that have influenced it. The history of Newport Beach begins with the bay. It is the story of how natural forces shaped the land and coast and how people responded to these changes. It is believed that Newport Bay formed about 300,000 years ago when a precursor of the Santa Ana River flowed into the northern end of the bay and carved a deep canyon. Rising sea levels submerged the bay until about 15,000 to 25,000 years ago. When the bay reemerged, the Santa Ana River, as it did throughout its history, had shifted across the coastal plain and now flowed into the ocean at Alamitos Bay. 10,000 to 12,000 years ago, aboriginal hunters and gatherers were first drawn to this area by the rich bounty of the bay and ocean. These original inhabitants supplemented their diet with a variety of meat from marine resources, including shellfish, fish, and birds and probably ventured out into the ocean in rafts to fish for Sheepshead, Blacksmith, and Giant Kelpfish. The most recent native people were the Tongva (Gabrielinos) and the Acjachemem (Juanenos), who lived in small villages around the bay until the beginning of the Mission period in the 1770's. Tongva millingstone During the Mission period, the hills above the bay were part of a vast open cattle range of the Mission San Juan Capistrano. Early Spanish names for the bay were Bolsa de Quigara (bay with high banks) or Bolsa de Gengara, in reference to a nearby Indian village. After Mexico gained independence from Spain in 1831, the mission lands were broken up and redistributed through land grants. In 1837, the bay became a part of Rancho San Joaquin under the ownership of Jose Andres Sepulveda. Floods and droughts caused Sepulveda to sell the ranch in 1864 and it eventually became a part of the expansive Irvine Ranch. The bay at that time was open to the ocean and part of a large estuary that stretched from Huntington Beach to Corona del Mar. In 1825, unusually heavy floods again shifted the mouth of the Santa Ana River to the southeast of the Huntington Beach mesa. Sand carried by the river began to form a peninsula. Over the next thirty CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 1 -4 years, the peninsula made steady progress in a southeasterly direction. By 1857, the eastern tip had reached to approximately where Bay Island is today. Floods during the winter of 1861 -62 extended the peninsula to the present harbor entrance. This barrier beach forced the Santa Ana River to flow parallel to the coast. The accretion of silt made the bay shallower and spread marsh vegetation. In the late 1860's, the bay was used as a landing to load hides, tallow, hay and other goods for export. In September 1870, Captain Samuel S. Dunnells' steamer Vaquero ventured into the bay to offload a cargo of lumber and shingles. Captain Dunnells soon established "Newport Landing" by constructing a small wharf and warehouse near the west end of the present Coast Highway /Newport Bay Bridge. James McFadden and his younger brother Robert acquired the landing in 1875 and for the next nineteen years operated a thriving commercial trade and shipping business. However, the bay was not yet a true harbor and sand bars and a treacherous bay entrance caused the McFadden Brothers to move the shipping business to the oceanfront by constructing a large pier on the sand spit that would become the Balboa Peninsula. The site was ideal because a submarine canyon (Newport Submarine Canyon), carved along with Newport Bay by the ancient Santa Ana River, provided calm waters close to the shore. McFadden Wharf was completed in 1888 and was connected by rail to Santa Ana in 1891. For the next eight years, the McFadden Wharf area was a booming commercial and shipping center and a company town began to grow. However, in 1899, the Federal Government allocated funds for major improvements to a new harbor at San Pedro, which would become Southern California's T ! : major seaport. The McFadden Wharf `r and railroad was sold to the Southern Pacific Railroad that same year, signaling the end of Newport Bay as • a commercial shipping center. 1875 smey map of Newport Bay In 1902, James McFadden sold his Newport townsite and about half of the Peninsula to William S. Collins, who saw Newport Bay's resort and recreation potential. Collins took on Henry E. Huntington as a partner in the Newport Beach Company. Huntington had acquired the Pacific Electric railway system and used it to promote new communities outside of Los Angeles. In 1905, the Pacific Electric "Red Cars" were extended to Newport and then to Balboa the following year. Also in 1906, Collins began dredging a channel on the north side of the bay and deposited the sand and silt on tidelands that would become Balboa Island. Between 1902 and 1907, many of Newport Beaches' waterfront communities were subdivided, including West Newport, East Newport, CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 1 -5 Bay Island, Balboa, and Balboa Island. This established the grid system of small lots and narrow streets and alleys that still exists today in these areas. In 1906, the City of Newport Beach, consisting of West Newport and Balboa Peninsula, incorporated. In 1916, most of Balboa Island was annexed, followed by Newport Heights in 1917, Corona del Mar in 1924, and the balance of Balboa Island in 1927. In 1923, the dredging and filing of mud Flats that would become Lido Island began. At this time, Newport Beach was still a beach town, with most of the homes being constructed as beach cottages and second homes used for vacations. However, public safety concerns would move Newport Beach to embark on a series of projects to protect and improve the harbor and ultimately lead to the next stage in the City's development. Newport Beach circa 1910 At that time, the channels in the bay were narrow, shallow, and tortuous. Two massive Floods in December 1914 and January 1916 filled the harbor and beaches with silt and debris. This and an increasing number of drownings at the harbor entrance prompted Newport Beach voters to approve funds to build the west jetty. In 1919, Orange County voted for funds to extend the jetty and build a dam to divert the Santa Ana River from the bay and Flow directly into the ocean west of the City. The harbor improvements turned a small colony of fishermen into a major industry. In the1920's the sport fishing and commercial fishing would become the major source of income in Newport Beach. In 1921, the first of four commercial fish canneries was built on the Rhine Channel. The boatyard industry also began to Flourish. The great increase in the number of commercial and recreational boats in the 1920s led to calls for further harbor improvements. Also, the consensus gradually changed from development of a commercial harbor to a recreational harbor. In 1928, Newport Beach voters approved funds for work on the west and east jetties. In 1933, a federal grant and matching funds from an Orange County bond measure provided funds to extend the jetties and dredge the entire Lower Newport Bay, On May 23, 1936, Newport Harbor was dedicated. The completion of the harbor improvements increased recreational and commercial boating activity. The South Coast Shipyard produced all types of pleasure craft. With the United States entry into World War II, the boatyards quickly shifted to the wartime production. South Coast and the new Lido Shipyard produced minesweepers, sub chasers, and other military vessels. By the end of the war, the summer beach resort town had become a city of 10,000 people. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 1 -6 The postwar boom in Southern California led to the next stage in the City's development. The Irvine Company began to open some of its vast land holdings east of the City to residential development. During the 1950's the City annexed over 4,382 acres, more than tripling its land area. In 1960, the City had a population of 26,565 people. The 1960's saw the development of major employment, commercial, and educational centers in Orange County. The City annexed another 2,280 acres, including the Newport Dunes and the future sites of Newport Center and Fashion Island. In 1970, the City's population had reached 49,442 people. The expansion and development of the City led to a period of introspection in the 1970's. In 1969, a citizens committee completed work on a set of community goals titled Newport Tomorrow, which served as the basis for the City's 1973 General Plan. Newport Tomorrow also served as a catalyst for a series of special studies, which resulted in new development controls. In 1970, the Lower Newport Bay Civic District study began to analyze development around the lower bay, including height limits, the preservation of marine service facilities, public access, and view corridors. The study resulted in the adoption of the Shoreline Height Limitation Ordinance in 1972, which established new height and bulk restrictions around the bay. Height limits along Pacific Coast Highway and other commercial areas were lowered from 85 to 26 feet. Residential development standards for Corona del Mar, Balboa Island, West Newport, and the Balboa Peninsula followed in 1973 and 1974, which set stricter Floor area and height limits and higher off -street parking and open space requirements. A proposed land exchange between the County of Orange and the Irvine Company cleared the way for the development of the Upper Newport Bay with residential uses and marinas in the early 1960's. Newport Beach residents began a movement to preserve the Upper Bay, first winning local government support, then at the County, then at the State. In 1973, an appellate court ruled that a proposed land exchange Upper Newport Bay Grca 1952 was unconstitutional. In 1974, a committee composed of Federal, State, and local agencies and interested members of the community produced a plan that recommended preservation of the Upper Bay. The Upper Newport Bay Ecological Reserve (Upper Newport Bay Marine Park) was created in 1975 as result of the purchase of 527 acres of land in and around the bay CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 1 -7 from the Irvine Company and the transfer of 214 acres of tidal wetlands from the County of Orange to the State. The City continued to expand and develop in the 1980's and 1990's, albeit at a slower pace. The City's population was 65,283 in 1980, and increased to 66,643 in 1990. Land use and development policies continued to be refined. In 1988, comprehensive amendments to Land Use and Circulation Elements of the General Plan were adopted to establish reasonable density and intensity limits, allow for modest growth, and to better correlate land uses with the circulation system. Specific plans were adopted for the older commercial districts on the Balboa Peninsula, including Cannery Village, McFadden Square, and Balboa Village. By the year 2000, the population had reached 70,032. Newport Beach in 2004 Coastal History Notes 1905 Balboa Pier and Balboa Pavilion constructed. 1909 Balboa Island Ferry service established. 1911 Fast yacht dub established in Newport Beach. 1913 Frost Life Saving Corps organized. 1917 First commercial fish cannery opens. 1918 Newport to Balboa boardwalk consWried. 1922 Dike Kahanamoku introduces wing at Newport. 1922 City purchases Newport Pier (McFadden Wharf). 1923 First public restrooms built at McFadden Place. 1923 First City lifeguard service created. 1934 Sea salt works dike constructed in Upper Bay. 1936 Fun Zone opens. 1948 First Newport- Ensenada Yacht Race. 1958 Newport Dunes opens. 1969 Floods breach salt works dikes, sifts Upper Bay. 1971 Fun Zone saved from condominium development 1982 Upper Newport Bay dredged to dear sift build -up. 1990 First LCP Land Use Plan certified. 200D Upper Newport Bay Interpretative Center opens. At the beginning of the 21'` Century, Newport Beach is a community of 75,662 people covering 25.4 square miles, including 2.5 square miles of bay and harbor waters. The City has over 30 miles of bay and ocean waterfront. Over 63 percent of the City is in the coastal zone. While Newport Beach is no longer a sleepy little beach town, the bay and beach continue to play an important role in the community's character and economy. Newport Harbor is the largest small craft harbor in the United States with over 9,000 boats at 2,119 commercial slips and side ties, 1,221 bay moorings, and 1,230 piers. Beach attendance averages 9.4 million people annually. Newport Beach continues to be a major visitor destination. In FY 2001, the City received 7.2 million visitors (people other than those who reside or work here). Over 80 percent of the City's visitors are here for purposes of leisure. The City has 16 hotel properties with 2,977 rooms and 535 seasonal housing units. However, the vast majority are day visitors. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 1 -8 CHAPTER 2 2.0 Land Use and Development 2.1 Land Use The Coastal Land Use Plan was derived from the Land Use Element of the General Plan and is intended to identify the distribution of land uses in the coastal zone. The Land Use Element may contain more precise development limits for specific properties. Should a conflict exist, the land use intensity or residential density limit that is most protective of coastal resources shall take precedence. However, in no case, shall the policies of the Coastal Land Use Plan be interpreted to allow a development to exceed a development limit established by the General Plan or its implementing ordinances. 2.1.1 Land Use Designations Policy 2.1.1 -1 The following land use designations establish the type, density and intensity of land uses within the coastal zone. If there is a conflict between the development limits of the Land Use Element and the Coastal Land Use Plan, the provision that is most protective of coastal resources shall take precedence.

Main street CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -S Planning Study Area 5 (Balboa Bay Club). The Balboa Bay Club is located on Coast Highway between the Orange Coast College David A. Grant Collegiate Rowing Centerand the Bayshores community. The property consists of approximately 12.6 acres of State tidelands held in trust by the City of Newport Beach and leased to the Balboa Bay Club, Inc. It is currently developed Balboa Bay Gub with many uses, including visitor - serving, recreational, boating, restaurant and banquet, and residential facilities. The site is designated for a mixture of Recreational and Marine Commercial and High Density Residential A and is allowed a Floor area ratio of 0.5. Residential development is allowed in conjunction with commercial development up to a maximum total Floor area ratio of 1.0 and 144 dwelling units. The use of tidelands for a private club and for private residences is in conflict with the public trust doctrine. Assembly Bill 3139 (Chapter 728, Statutes of 1994) provided for redevelopment of the private club portion of the property to allow full public access and the continuation of the residential uses to December 31, 2044 (see Section 2.6). Planning Study Area 6 (Newport Dunes). The Newport Dunes consists of 100 acres of State tidelands property on the Upper Newport Bay held in trust by the County of Orange. This area is designated open space and is intended for recreational and visitor- serving uses. Land uses and development limits are established pursuant to the Newport Dunes Settlement Agreement. The site is currently Newport Dunes AquaGC Park developed with a 406 -space recreational vehicle park, a 450 -slip marina, a restaurant, dry boat storage, boat launching facilities, surface parking, and beach day use facilities. This area also includes an undeveloped site for a 275 -room hotel with up to 500,000 square feet of floor area, 27,500 square feet of floor area for restaurants, and 5,000 square feet of floor area for retail commercial. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -9 The Newport Dunes provides a variety of recreational and visitor - serving uses. Protection, and if feasible, expansion and enhancement, of the diversity of these uses should be a part of any new development application. Particular attention should be given to provision of lower cost uses. The Newport Dunes is located on the Upper Newport Bay and surrounded by coastal bluffs. Any application for new development must given special consideration to the protection of the water quality of the bay and adjacent natural habitats. Any new development should be designed and sited to minimize impacts to public views of the water and coastal bluffs. 2.1.2 Coastal Land Use Plan Map The Coastal Land Use Plan Map depicts the land use designation for each property and is intended to provide a graphic representation of policies relating to the location, type, density, and intensity of all land uses in the coastal zone.

Aerial view of the Newport Pier area CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -10 2.2 General Development Policies 2.2.1 Location of New Development Coastal Act policies related to the location of new development that are relevant to Newport Beach include the following: 30250 (a). New residential, commercial, or industrial development, except as otherwise provided in this division, shall be located within, contiguous with, or in close proximity to, existing developed areas able to accommodate it or, where such areas are not able to accommodate it in other areas with adequate public services and where it will not have significant adverse effects, either indKidually or cumulatively, on coastal resources. In addition, land divisions, otter than leases for agricultural uses, outside existing developed areas shall be permited only where 50 percent of the usable parcels in the area have been developed and the created parcels would be no smaller than the average size of surrounding parcels. The Coastal Act provides for the protection of coastal resources by requiring that new development be located in areas in close proximity to existing development with available public services to minimize the impacts associated with the extension of infrastructure and services. Most of the areas of Newport Beach's coastal zone were developed during the first half of the 2& Century. Therefore, new development within the coastal zone will occur in the form of redevelopment or infill development within or adjacent to existing developed areas. These areas have adequate public services or are capable of having public services extended or expanded without significant adverse effects on coastal resources. The only exception is the 505 -acre Banning Ranch property. Save for oil field facilities, Banning Ranch is undeveloped, but is contiguous to the developed areas of Newport Beach, Costa Mesa, and Huntington Beach. Banning Ranch is designated as a deferred certification area due to unresolved land use and resource protection issues (see Section 2.2.4). Policies: 2.2.1 -1. Continue to allow redevelopment and infill development within and adjacent to the existing developed areas in the coastal zone subject to the density and intensity limits of the Coastal Land Use Plan. 2.2.1 -2. Require new development be located in areas with adequate public services or in areas that are capable of having public services extended or expanded without significant adverse effects on coastal resources. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -11 2.2.2 Coastal Development Review Coastal Act policies related to development review that are relevant to Newport Beach include the following: 30600 (a). Except as provided in subdivision (e), and in addition to obtaining any other permt required by law from any local government or from any state, regional, or local agency, any person, as defined in section 21066, wishing to perform or undertake any development in the coastal zone, ode than a facility subject to section 25500, shall obtain a coastal development permit. 30600 (d). After certification of its local coastal program or pursuant to the provisions of Section 30600.5, a coastal development permit shag be obtained from the local government as provided for in Section 30519 or section 30600.5. In order to ensure that development within the coastal zone is consistent with the LCP, the City will require a coastal development permit prior to commencement of any development in the coastal zone, with the exceptions of developments in areas where the Coastal Commission retains permit jurisdiction, developments determined to be categorically excluded according to the categories and standards established by the Coastal Commission, and developments determined to be excluded from the i' Beachfrom residential development on the Balboa Peninsula. coastal development permit requirements pursuant to Public Resources Code Section 30610. Policies: 2.2.2 -1. After certification of the LCP, require a coastal development permit for all development within the coastal zone, subject to exceptions provided for under the Coastal Act as specified in the LCP. 2.2.2 -2. Incorporate coastal development permit procedures into the implementation plan to ensure that all public and private development in the coastal zone is consistent with the LCP. 2.2.2 -3. Prior to approval of any coastal development permit, the City shall make the finding that the development conforms to the policies and requirements contained in the Coastal Land Use Plan.

(b) Every exclusion granted under subdivision (a) of tins section and subdivision of (e) Section 30610 shall be subject to temps and conditions to assure that no significant change in density, height or nature of uses will occur without Gather proceedings under this division, and an order granting an exclusion under subdivision (e) of Section 30610, but not under subdivision (a) of this section may be revoked at any time by the commission, t the cons iitons of exclusion are violated. Tide and submerged land beaches, and Ids immediately adjacent to the inland extent of any beach, or of the mean high tide line of the sea where there is no beach, and all lands and waters subject to the public mist shall not be excluded under either subdivision (a) of this sexton or subdivision (e) of section 30610. Section 30610 (e) of the Coastal Act provides for a category of development, or a category of development within a specifically defined geographic area, to be excluded from the coastal development permit provisions of the Coastal Act provided there is no potential for any significant adverse effect, either individually or cumulatively, on coastal resources or on public access to, or along, the coast. Residential Areas • On June 14, 1977, the Coastal Commission adopted Categorical Exclusion Order E- • 77 -5, at the request of the City of Newport Beach pursuant to Section 30610 (e) of the Coastal Act. The categorical exclusion is for the demolition and /or construction • of all single - family and two - family residences and their appurtenant facilities in most • residentially -zoned districts within the City of Newport Beach within the coastal zone. • The categorical exclusion, however, does not include the first row of lots adjacent to the beach, bay or wetlands nor is the categorical exclusion applicable to major • undeveloped residential sites within the coastal zone, Planned Community zoned • districts or gated communities within the City. In Resolution No. 9190, the City • Council found and determined that the exclusion applies only to Balboa Island, the • Balboa Peninsula, Cameo Highlands, Cameo Shores, Corona del Mar, Corona Highlands, Irvine Terrace, Lido Isle, Shorecliffs, the Upper Bay and West Newport. • Pursuant to Section 13249 (b) of the California Code of Regulations, a categorical • exclusion order automatically terminates upon the effective date of the delegation of • • CITY COUNCIL DRAFT 1 Local Coastal Program • Coastal Land Use Plan 2 -13 • • • development review authority to a local government. Therefore, Categorical Exclusion Order E -77 -5 will terminate when the LCP is certified and adopted. The categorical exclusion was adopted in recognition that the residential areas in question contained little vacant land and that new development consisted primarily of the conversion of single - family dwellings to two- family dwellings and the replacement and improvement of existing single - family and two- family residences. These residential areas consist of well - established neighborhoods. Development in the 27 years since the adoption of the categorical exclusion has continued to be in the form of redevelopment or infill projects. The permitted residential unit type and maximum density of the Coastal Land Use Plan reflect the predominant form of development in these areas. Residential floor areas and building heights have been strictly controlled since the early 1970's to insure that the scale, size, and character of new development is compatible with existing development in the surrounding area. Therefore, the City should seek a new categorical exclusion for these residential areas concurrently with certification of the LCP. Commercial Areas The Corona del Mar commercial area is generally located along Coast Highway between Avocado Street (including the southwest corner) and Hazel Drive. Only the south side of Coast Highway is located within the coastal zone. It has been zoned for commercial uses since 1936 and developed as a business district for over 75 years. The commercial area is completely urbanized and new development is limited to a maximum floor area to land area ratio of 0.75. Unlike other coastal commercial areas that largely serve the Coast Highway in Corona del Mar visitor market, Corona del Mar has the broadest base of local- serving retailers. The portion of the Corona del Mar commercial area located in the coastal zone is located 1,000 to 2,500 feet from the shoreline. Given this commercial area's considerable distance from the shoreline and minimal use by coastal zone users, there is no potential for significant adverse effects, either individually or cumulatively, on public access to the coast or on coastal resources. Therefore, the City should seek a categorical exclusion for this commercial area concurrently with certification of the LCP. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -14 Policies: 2.2.3 -1. Pursuant to Section 30610 (e) of the Coastal Act, request a categorical exclusion for the residential areas: Balboa Island, the Balboa Peninsula, Cameo Highlands, Cameo Shores, Corona del Mar, Corona Highlands, Irvine Terrace, Lido Island, Newport Center, Newport Heights, Newport Shores, Shorecliffs, Upper Newport Bay, and West Newport. 2.2.3 -2. Pursuant to Section 30610 (e) of the Coastal Act, request a categorical exclusion for the portion of the Corona del Mar commercial area located in the coastal zone, which consists of all commercial properties on the south side of Coast Highway between Avocado Street (including the southwest corner) and Hazel Drive. 2.2.3 -3. Incorporate the terms and conditions of categorical exclusions into the Zoning Code. 2.2.3 -4. Depict the properties covered by categorical exclusions on the Exclusion Areas Map. 2.2.4 Deferred Certification Areas Deferred Certification Area (DCA) refers to an area which has not been officially segmented for purposes of LCP preparation and where both the land use plan and implementation plan have been deferred to some future date in order to avoid delay in certifying the balance of the LCP. The Coastal Commission retains permit jurisdiction in all deferred certification areas. Banning Ranch. Banning Ranch consists of 505 acres located north of the Semeniuk Slough and Coast Highway West and east of the Santa Ana River. Nearly all of Banning Ranch (454 acres) is located within the City's sphere of influence in unincorporated Orange County. Oil and gas operations are conducted throughout the County portion of the property (West Newport Oil Field) pursuant to California Coastal Commission Exemption Banning Ranch CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -15 E -144. These operations consist of 483 producing, idle, injection, and abandoned well sites and related service roads, pipelines, storage, and other facilities. The property contains a number of sensitive habitat types, including southern coastal bluff scrub, alkali meadow, southern coastal salt marsh, southern black willow forest, coastal brackish marsh, and vernal pools. The property also contains steep coastal bluffs along the southern and western edges of the mesa. The bluff faces have been eroded in some areas to form a number of gullies and ravines. Future land uses for Banning Ranch are currently under review as part of a comprehensive update of the City of Newport Beach General Plan. Banning Ranch shall remain a deferred certification area until such time as the future land uses for the property are resolved and policies are adopted to address the future of the oil and gas operations and the protection of the coastal resources on the property. Policies: 2.2.4 -1. Designate the Banning Ranch property as an area of deferred certification until such time as the future land uses for the property are resolved and policies are adopted to address the future of the oil and gas operations and the protection of the coastal resources on the property. 2.2.4 -2. Depict the boundaries of deferred certification areas on the Coastal Land Use Plan Map and other applicable LCP maps. 2.2.4 -3.

This section is intended to establish policies to limit the expansion of nonconforming structures and uses to the maximum extent feasible and to bring these structures and uses into conformity in a timely manner, without infringing upon the constitutional rights of property owners. Policies: 2.2.5 -1. Legally established nonconforming structures may be maintained and repaired. Interior alterations, structural alterations, and additions shall be limited as follows. A. Nonstructural interior alterations shall not exceed 50 percent of the replacement cost of a nonconforming structure. B. Alteration of more than 25 percent of the structural elements of a nonconforming structure shall be subject to discretionary review and approval by the City. C. Additions shall be permitted to structures that are legally nonconforming due to reasons other than for parking, open space, floor area, or building bulk. Additions of more than 25 percent of the gross floor area of a nonconforming structure shall be subject to discretionary review and approval by the City. D. No alternations or additions to a nonconforming structure shall increase the degree of the structure's nonconformity. 2.2.5 -2. The enlargement or intensification of legally established nonconforming uses shall be limited to only those uses normally permitted by right or by the approval of a use permit, but which were made nonconforming by additional regulations of the district in which they are located. Such enlargement or intensification shall be subject to discretionary review and approval by the City and shall not increase the degree of the use's nonconformity. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -17 2.3 Visitor - serving and Recreational Development Coastal Act policies related to visitor- serving and recreational development that are relevant to Newport Beach include the following: 30213. Lower cost visitor and recreational facilities shag be protected, encouraged, and, where feasible, provided. Developments providing public recreational opportunities are preferred. 30221. Oceanfront land suitable for recreational use shag be protected for recreational use amt development %"ass presert and foreseeable future demand for public or commercial recreational activities that could be accommodated on the property is already adequately provided for in the area. 30222. The use of private lands suitable for visitor - serving commercial recreational facilities designed to enhance public opportunities for coastal recreation shell have priority over private residential, general industrial, or general commercial development, but not over agilctiare or coastal -dependent industry. 30223. Upland areas necessary to support coastal recreational uses shall be reserved for such uses, where feasible. 30250 (c). Visitor-serving facilities that cannot feasibly be located in edsting developed areas shelf be located in edsting isolated developments or at selected points of attraction for visitors. 2.3.1 Commercial Newport Beach has thirty-seven distinct commercial areas within the coastal zone. These areas range from small strip commercial areas to large hotel complexes. Most of the coastal zone's commercial development is in the City's older business districts. These business districts were originally developed to serve harbor - related businesses and industries and to serve the City's original residential areas. Over the years, portions of these business districts have been redeveloping to visitor - oriented retail, water - related businesses, recreational uses, and mixed commercial /residential projects. The Coastal Land Use Plan allows for the continuation of this trend, while continuing to provide businesses that serve the needs of residents and are essential to the harbor operations. Oceanfront Boardwalk near Newport Pier Visitor - serving and recreational activities are an important part of the character and economy of Newport Beach. In 2003, Newport Beach had 14 hotels, motels, timeshares, and bed & breakfast inns in the coastal zone and 18 citywide. These facilities provide a total of 2,287 rooms in the coastal zone and 3,520 rooms citywide. In FY 2001, Newport Beach received 7.2 million visitors (people other than those CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -18 who reside or work here). Over 80 percent of the City's visitors are here for purposes of leisure and the vast majority are day visitors. Other visitor - serving and recreational facilities located within commercial areas include restaurants, snack bars, boat rentals, sports equipment rentals, boat tours of the harbor, boat launching facili- ties, amusement and recreation facilities, and numerous shops selling specialized merchandise. Many of these facilities have become tourist attractions in their own right, such as the Balboa Pavilion, the Fun Zone, Balboa Ferry, the entire Marine Avenue area on Balboa Island, and certain restaurants. Edgewater boardwalk in Balboa Village Most of the lands suitable for visitor - serving and recreational uses are in the commercial areas surrounding and adjacent to the west end of Newport Harbor. Most of the waterfront land in this area has been designated for recreational and marine uses. Also, individual hotel and motel sites on the Balboa Peninsula, in West Newport, and adjacent to the Upper Newport Bay and other open space areas are designated for visitor - serving uses. A 2002 retail commercial market analysis verifies that the City's main coastal zone commercial areas largely serve the visitor market. In Balboa Village, Balboa Island, McFadden Square, and Mariner's Mile, visitors (people from outside each study area) account for the vast majority of retail sales. On Balboa Island, retail sales are dominated by apparel stores, specialty retail stores, and restaurants, which generally sell to tourists and other non - residents. In McFadden Square and Balboa Village, which are adjacent to beaches, restaurants are the single most prominent retail sales category, followed by apparel and sporting goods stores that primarily cater to visitors. Visitor Spending in Coastal Zone Commercial Area Percentage of Retail Spending By Visitors Balboa Island 85.1% Balboa Village 80.9% Corona del Mar 75.8% Lido - Cannery 48.0% McFadden Square 86.0% Mariner's Mile 96.6% source: Newport Beach General Plan Update Retail Commercial Market Analysis, December 2002. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -19 The lower percentage of retail spending by visitors in Lido - Cannery is due primarily to the presence of two large grocery stores that serve West Newport, Lido Isle, and the Balboa Peninsula and constitute over half of the retail sales. The extremely high percentage of retail spending by visitors in Mariner's Mile is due primarily to the high concentration of restaurants, entertainment boat operations, automobile and boat dealers, and marine - related retail stores. While the coastal zone commercial areas are heavily oriented to the visitor market, some commercial areas are also underperforming economically. McFadden Square and Balboa Village have sales per square foot that are below national averages in nearly every retail category. Many businesses have to drastically reduce their hours of operation or close down completely during the winter months. This often gives an impression of economic stagnation and can detract from the ability of the commercial district to attract customers. Therefore, these areas should continue to be permitted a wider range of commercial uses in order to maintain year- around economic viability. While a high proportion of spending in Corona del McFadden Square shops on the Oceanfront Mar Is by visitors, many of the categories Boardwalk represented are not necessarily visitor - oriented. About half of the retail sales are generated by grocery stores and furniture, home furnishings, and home improvement stores. This indicates that much of the retail spending in Corona del Mar is from customers from neighboring communities, but who are not necessarily coastal zone visitors. This is to be expected since the portion of the Corona del Mar commercial area located in the coastal zone is 1,000 to 2,500 feet from the shoreline. Policies: 2.3.1 -1. Permit visitor - serving retail and eating and drinking establishments in all commercially designated areas. 2.3.1 -2. Continue to provide waterfront- oriented commercial uses, including eating and drinking establishments and recreation and entertainment establishments, as a means of providing public access to the waterfront. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -20 2.3.1 -3. On land designated for visitor - serving and /or recreational uses, give priority to visitor - serving commercial recreational facilities designed to enhance public opportunities for coastal recreation over other commercial uses, except for agriculture and coastal- dependent industry. 2.3.1 -4. Protect oceanfront land designated for visitor- serving and /or recreational uses for recreational use and development unless present and foreseeable future demand for public or commercial recreational activities that could be accommodated on the property is already adequately provided for in the area. 2.3.2 Open Space and Tidelands /Submerged Lands Newport Beach's open space designated areas in the coastal zone include beaches, parks, golf courses, yacht clubs, and environmentally sensitive habitat areas and other natural resources. These areas provide a wide range of recreational and visitor - serving uses and facilities. Nearly all of the oceanfront land, including the entire Balboa Peninsula, is public beach. In total, there are over 276 acres of public beaches on the shoreline. There are also approximately 415 acres of recreational and view parks on or adjacent to the shoreline. Rowing in the Upper Newport Bay Tidelands and submerged lands are State lands held in trust by the City of Newport Beach, the County of Orange or State resource agencies. These lands are subject to the public trust doctrine and are limited to public trust uses, such as navigation, fisheries, commerce, public access, water - oriented recreation, open space and environmental protection. The waters of Newport Bay and of the Pacific Ocean adjacent to Newport Beach are used for a wide variety of recreational activities, including boating, diving, excursions, fishing, kayaking, paddle boarding, parasailing, rowing, sailing, surfing, swimming, and wind surfing. Development in the form of marinas, moorings, piers, and equipment rentals provide recreational opportunities and access to the water. The Newport Dunes Aquatic Park is on 100 acres of State tidelands property held in trust by the County of Orange. The park is leased to a private operator and provides CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -21 a recreational vehicle park, campgrounds, a marina, boat launching and storage facilities, beach day use facilities, and a swimming lagoon. Policies: 2.3.2 -1. Continue to use public beaches for public recreational uses and prohibit commercial uses on beaches that interfere with public access and enjoyment of coastal resources. 2.3.2 -2. Continue to designate lands to provide visitor - serving and recreational facilities and view parks on or adjacent to the shoreline. 2.3.2 -3. Cooperate with the County of Orange to continue to provide a variety of visitor - serving and recreational uses at the Newport Dunes, including recreational vehicle park and campground areas as a means of providing alternative and lower cost overnight accommodations. 2.3.24. Continue to administer the use of tidelands and submerged lands in a manner consistent with the tidelands trust. P'irate's Cove CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -22 2.3.3 Lower Cost Visitor and Recreational Facilities Camping at Newpon Dunes Newport Beach currently provides a variety of overnight visitor accommodations in all price ranges. In 2003, Newport Beach had 14 hotels, motels, timeshares, and bed & breakfast inns in the coastal zone providing 2,287 rooms. Peak summer rates ranged from $69 to $750 per night. The Newport Dunes provides a 406 -space recreational vehicle park, with tent camping permitted. In 2003, peak summer rates ranged from $42 to $139 per night. A significant number of single - family homes, condominiums, and apartments serve as overnight visitor accommodations. Each year, hundreds of dwelling units in coastal zone residential areas are rented on a weekend, weekly or monthly basis. Most of these dwelling units have beach or bay front locations or are located within walking distance to the water. Because they typically provide additional sleeping accommodations and fully equipped kitchens, they provide an accommodation option comparable to or less expensive than staying in hotels and going out to restaurants for meals. Particularly for large families, these dwelling units provide an affordable alternative to hotels and motels. In 2003, weekly rates are as low as $900. The City requires short-term lodging permits for dwelling units rented for 30 days or less to insure that overcrowding and public nuisances do not result in adverse impacts to residential areas, coastal access, and coastal resources (see Section 2.7). In 2003, the City issued over 800 short-term lodging permits. The City provides approximately 360 acres of public beaches and parks in the coastal zone, which are available free of charge. Also, the County's Upper Newport Bay Nature Preserve and the day use facilities at the County's Newport Dunes Aquatic Park are available free of charge. These areas offer a variety of free or lower cost recreational opportunities and are discussed further in Section 3.2. The City, County, and private organizations also provide several coastal - related educational and interpretative facilities and programs that are either free or have a nominal charge. These include the Muth Interpretative Center in the Upper Newport Bay Nature Preserve, the Back Bay Science Center on Shellmaker Island, the Newport Aquatic Center at North Star Beach, and the Newport Harbor Nautical Museum. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -23 Policies: 2.3.3 -1. Protect, encourage and provide lower -cost visitor accommodations, including campgrounds, recreational vehicle parks, hostels, and lower - cost hotels and motels. 2.3.3 -2. Encourage new overnight visitor accommodation developments to provide a range of rooms and room prices in order to serve all income ranges. Consistent with Section 30213 of the Coastal Act, the City shall in no event (1) require that overnight room rental be fixed at an amount certain for any privately owned and operated hotel, motel, or other similar visitor - serving facility located on either public or private land; nor (2) establish or approve any method for the identification of low or moderate income persons for the purpose of determining eligibility for overnight room rentals in any such facilities. 2.3.3 -3.

Continue to issue short- term lodging permits for the rental of dwelling units as a means of providing lower -cost overnight visitor accommodations while continuing to prevent Maxero Avenue Beach conditions leading to increase demand for City services and adverse impacts in residential areas and coastal resources. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -24 2.4 Coastal - dependent/related Development Coastal Act policies related to coastal-dependent and coastal- related development that are relevant to Newport Beach include the following: 30255. Coastal -dependent developments shall have priority over odw developments on or near the shoreline. Except as Provided elsewhere in this division, coastal-dependent developments shall not be sited in a wetland. When appropriate, coastal-related developments should be accommodated within reasonable proximity to the coastal -dependent uses they supper 2.4.1 Commercial Newport Harbor supports a wide range of coastal - dependent and coastal - related commercial uses. These include passenger /sightseeing boats, passenger - fishing boats, boat rentals and sales, recreational equipment rentals, entertainment boats, boat/ship repair and maintenance, and harbor maintenance facilities. These uses play an important role in the character of the harbor and provide the services necessary to sustain one of the world's great small boat harbors. Coastal- dependentl- related Coastal - dependent refers to a development or use that requires a site on, or adjacent to, the sea to be able to function at all. Coastal - related refers to a development or use that is dependent on a coastal - dependent development or use. Over the past 20 years, a number of marine - related businesses and industries in Newport Beach have moved to inland areas. This is reflective of a regional trend, largely due to increased environmental regulation in California affecting fiberglass manufacturing processes, as well as real estate price inflation in coastal communities. The Recreational and Marine Commercial (CM) designation is the primary method of providing for the Basin Marine Shipyard continuation of coastal- dependent and coastal- related commercial uses on or near the bay. The CM designation is applied to areas that have historically provided marine - related businesses and industries and visitor - serving and recreational areas. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -25 Policies: 2.4.1 -1. Give priority to coastal - dependent uses over other uses on or near the shoreline. 2.4.1 -2. When appropriate, accommodate coastal - related developments within reasonable proximity to the coastal- dependent uses they support. 2.4.1 -3. Design and site new development to avoid impacts to existing coastal - dependent and coastal - related developments. When reviewing proposals for land use changes, give full consideration to the impact on coastal- dependent and coastal - related land uses including not only the proposed change on the subject property, but also the potential to limit existing coastal- dependent and coastal - related land uses on adjacent properties. 2.4.1 -4. Maintain the Recreational and Marine Commercial designation in areas on or near the bay to encourage a continuation of coastal - dependent and coastal - related uses. 2.4.1 -5. Encourage and maintain facilities that serve marine - related businesses and industries unless the demand for such facilities no longer exists. 2.4.2 Public Facilities Kerckhoff Marine Laboratory in Corona del Mar Lands designated for public facilities that are on or adjacent to the shoreline are primarily used for public parking, public safety facilities, and educational facilities. These include coastal - dependent/related institutional uses, such as the Orange Coast College David A. Grant Collegiate Rowing Center, the Sea Scout Base, and the Kerckhoff Marine Laboratory. Policy 2.4.2 -1. Continue to designate lands for coastal - dependent/related educational and recreational uses. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2.26 2.5 Tidelands and Submerged Lands Coastal Act policies related to tidelands and submerged lands that are relevant to Newport Beach include the following: 30213. Lower cost visitor and recreational facilities shall be protected, encouraged, and, where feasible, provided. Developments providing public recreational opportunities are preferred. 30221. oceanfront land suitable for recreational use shaft be protected for recreational use and development unless present and foreseeable future demand for public or commercial recreational activities that could be accommodated on the property is akeady adequately provided for in the area. 30223. Upland areas necessary W support coastal recreational uses shall be reserved for such uses, where feasible 2.5.1 The Tidelands Trust Tidelands and submerged lands are subject to a public trust that, among other things, limits their use to navigation, fishing, commerce, public access, water- oriented recreation, open space and environmental protection. Tidelands and submerged lands within the corporate limits of Newport Beach are, with very limited exceptions, owned by the State. The vast majority of tidelands and submerged lands in Newport Beach have been granted to the City or the County of Orange to administer in a Balboa Yacht Basin manner consistent with the public trust limitations relative to use of the property and revenue derived from that use. The tideland boundary in Newport Harbor has been, for virtually all of the properties, established by court judgments stemming from a series of lawsuits filed in the 1920's and 1930's. Newport Beach tidelands also include large portions of the City's ocean beaches and land covered by the Pacific Ocean from the shoreline three miles out to sea and between the Santa Ana River and the east end of the Cameo Shores tract. 2.5.2 Tidelands Leases Chapter 494 of the Statutes of 1919 granted to the City of Newport Beach all tidelands and submerged lands that were within its corporate limits at that time. Additional tidelands were granted by Chapter 70 of the Statutes of 1927. These tidelands and submerged lands consist primarily of the land bayward of the bulkhead and portions of bay beaches in the Lower Bay. The Beacon Bay Bill (Chapter 74, CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -27 Statues of 1978) regranted to the City of Newport Beach all tidelands and submerged lands that were within its corporate limits on July 25, 1919. The Beacon Bay Bill established limitations on the use of tidelands and submerged lands to those in which there is a general statewide purpose, including the establishment, improvement and conduct of a public harbor, recreational facilities open to the public, and the preservation and enhancement of the lands in their natural state. The Beacon Bay Bill also modified some of the public trust restrictions on certain properties, such as portions of Beacon Bay and the Balboa Bay Club, subject to a requirement that revenue generated by these properties be used for public trust purposes. Beacon Bay Beacon Bay refers to an area located between Promontory Bay and the Balboa Island Channel. This area was tidelands that were filled and reclaimed in the 1920s as the result of an improvement plan, which included the development of a harbor facility that would become the Balboa Yacht Basin. Chapter 200 of the Statutes of 1931 allowed the area west of the Balboa Yacht Basin (designated as Beacon Bay) to be leased for residential purposes. A 72 -unit residential subdivision was developed in the 1930s, which Public beach at Beacon Bay included 35 homes located on approximately 4 acres of State tidelands. As indicated above, the Beacon Bay Bill released the residential lots of Beacon Bay located within State tidelands from the public trust land use limitations and allows existing leases to continue. These leases are limited to terms not to exceed 50 years and lease revenues have to be deposited into tidelands trust funds. Senate Bill 573 (Chapter 317, Statutes of 1997) revised the Beacon Bay Bill to require the residential lease revenue be deposited into specific tidelands trust funds. The current lease runs to June 27, 2043. In Fiscal Year 2002 -03, the City of Newport Beach received over $729,000 in lease revenues from Beacon Bay, which were deposited in tidelands trust funds and State Lands Commission Land Bank Fund. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -28 Balboa Bay Club The Balboa Bay Club and Resort is on approximately 12.6 acres of State tidelands held in trust by the City of Newport Beach and leased to the Balboa Bay Club, Inc. The property is located on the south side of the 1200 block of West Coast Highway and was filled and reclaimed in the 1920s as part of a public project to develop the Lower Bay as a harbor. The property is currently developed with a 132 - room resort hotel, restaurant, spa, private club facilities, and 144 -unit Bayfront walkway at the Balboa Bay Club and Resort apartment complex. The State Lands Commission has determined that the use of tidelands for private residential purposes is in conflict with the public trust limitations on use. This conflict was first addressed in the Beacon Bay Bill (Chapter 74 of the Statutes of 1978) and later in Assembly Bill 3139 (Chapter 728, Statues of 1994). AB 3139 recognized that the lease of the apartment complex (identified as Parcel D) for residential purposes provides fiscal and economic benefits to the public trust and a means of improving public access. Under the provisions of AB 3139, lease revenues are placed in tidelands trust funds to provide facilities and services that directly support public use of tidelands and submerged lands. Income from the apartments provides an income stream that allowed the lessee to finance the redevelopment of the club to transition it from a private membership facility to visitor - serving commercial land uses. AB 3139 therefore allows Parcel D to be leased for residential purposes until no later than December 31, 2044. In Fiscal Year 2002 -03, the City of Newport Beach received over $1,870,000 in lease revenues from Parcel D, which were deposited in tidelands trust funds and State Lands Commission Land Bank Fund. The redevelopment of the Balboa Bay Club was completed in 2003 and provides public access to the hotel, restaurant, spa, the main parking lot, and a public walkway to and along the bulkhead. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -29 Harbor Island Developed in 1926, Harbor Island is a 35 -lot single - family community on a private island located between Linda Isle and Collins Island. Portions of tidelands surrounding Harbor Island have been filled or reclaimed and are no longer submerged or below the mean high tide line. Harbor Island residents have improved these lands with landscaping and other improvements. The State, through the adoption of Chapter 715, Statues of 1984, found that these lands are generally inaccessible to the public and, in their present condition, are not suitable for public trust uses. Both the County of Orange (most of the subject lands are County tidelands) and City of Newport Beach are authorized to allow the Harbor Island tidelands to be used for non - permanent recreational and landscaping uses. These leases are limited to terms of 49 years or less and lease revenues have to be deposited into tidelands trust funds. Policies: 2.5.2 -1. Continue to administer the use of tidelands and submerged lands in a manner consistent with the tidelands trust and the Beacon Bay Bill (Chapter 74, Statues of 1978), SB 573 (Chapter 317, Statues of 1997), AB 3139 (Chapter 728, Statues of 1994), and Chapter 715, Statues of 1984. 2.5.2 -2. Give full consideration to the public's right of access to the ocean, beach, and bay and to the provision of coastal- dependent uses adjacent to the water in the leasing or re- leasing of publicly owned land. 2.5.2 -3. Give full consideration to the consistency of the proposed use with the public trust restrictions and the public interest at the time any tideland lease is re- negotiated or renewed. 2.5.24. Negotiate or renegotiate tidelands leases at the fair market value based on the uses authorized in the lease and use the funds as required by law or the public trust. 2.5.2 -5. Require public access in a manner consistent with the policies of the Coastal Act and this LCP when the City issues new leases of public land, or renew existing leases. This requirement shall be understood to apply to all other public leaseholds in the coastal zone, including beaches leased to the Lido Isle Association. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -30 2.6 Industrial Development Coastal Act policies related to industrial development that are relevant to Newport Beach include the following. 30250 (b) Where feasible, new hazardous industrial development shall be located away from existing developed areas. 30260. Coastal -dependent industrial facilities shall be encouraged to locate or expand within existing sites and shall be permitted reasonable long -term growth where consistent with this division. However, where new or expanded coastal - dependent industrial facilities cannot feasibly be accommodated consistent with other policies of this division, they may nonetheless be permitted in accordance with this section and Sections 30261 and 30262 if (1) alterative locations are infeasible or more environmentally damaging; (2) to do otherwise would adversely affect the public welfare; and (3) adverse environmental effects are mitigated to the maximum extent feasible. 30262. Oil and gas development shall be permitted in accordance with Section 30260,... None of the City's industrial areas are located within the coastal zone. However, portions of Cannery Village (SP -3) are designated for a mixture of general commercial and light industrial uses to encourage marine - related business. When Newport Beach adopted its charter in 1954, oil and gas exploration, drilling, production, and refining was banned in the City. However, one oil field operation existed prior to the ban. The Newport Oil am: Field is located in the western portion of Commercial and light industrial uses in Cannery Village Newport Beach. The field was divided into two areas known as the Cagney and Beach areas. The Beach Area discovery well was drilled in 1922 and discovery well in the Cagney Area was drilled in 1947. The Beach Area has been abandoned, but there were still 3 gas - producing wells in the Cagney Area. Oil and gas operations are also conducted throughout the County portion of the Banning Ranch property (West Newport Oil Field) pursuant to California Coastal Commission Exemption E -144. Banning Ranch is a deferred certification area due to unresolved issues relating to land use, the future of the oil and gas operations, and the protection of the coastal resources on the property (see Section 2.2.4). The City of Newport Beach and other coastal communities in Southern California have long opposed the federal government's offshore oil leasing programs. Newport Beach residents and visitors rely heavily on the bay and oceanfront beaches for recreation, and much of the City's economy is based upon its natural resources. Development of offshore tracts creates visual impacts and poses the threat of CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -31 significant oil spills and resulting environmental damage. Policies: 2.6-1. Coastal- dependent and coastal - related industrial uses shall have priority over other industrial uses on or near the shoreline. 2.6-2. Prohibit new onshore oil and gas development facilities, except as may be necessary in conjunction with the operation of the West Newport Oil Field, including the City of Newport Beach oil facilities. 2.6-3. Prohibit the construction of West Newport Oil Field operations onshore oil processing, refining or transportation facilities, including facilities designed to transport oil produced from offshore tracts, with the exception of slant drilling from onshore oil fields. 2.6-4. Continue to monitor the federal government's offshore oil leasing programs to insure the City and its citizens are fully aware of all proposed offshore activities, which could adversely affect the coastal environment, including participation in the Local Government Coordination Program or other similar programs. 2.6-5. Oppose and lobby against proposed lease sales off the coast of Orange County and elsewhere in the Southern California region, which could adversely affect the environment or the economy of the City of Newport Beach. 2.6-6. Assist jurisdictions in other areas of the state that are opposed to offshore lease sale programs in their vicinity. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -32 2.7 Residential Development Coastal Act policies related to residential development that are relevant to Newport Beach include the following: 30007. Nothing in this division shall exempt local governments from meeting the requirements of state and federal law with respect to providing low -and moderatemincome housing, replacement housing, relocation benefits, or any other obligation related to housing imposed by existing law or any law hereafter enacted. 30222. The use of private lands suitable for visitor - serving commercial recreational facilities designed to enhance public opportunities for coastal recreation shall have priority over private residential, general industrial, or general commercial development, but not over aviculture or coastal -deoendent industry. Newport Beach has a wide variety of residential development types in the coastal zone, ranging from low- density single - family detached subdivisions to high - density high -rise condominiums. Most of the residential areas in the coastal zone were originally subdivided in the early 2& Century, with many developments marketed as vacation home sites. This established the grid system of small lots and narrow streets and alleys that still exists today. These subdivision characteristics and the development of two- family and multi - family development have resulted in relatively high residential densities in Newport Beach's coastal neighborhoods. Coastal zone residential areas are almost completely built out, with the exception of the Banning Ranch area (see Section 2.2.4). Most residential building activity consists of remodeling and /or the total reconstruction of existing dwelling units. Newport Beach's proximity to major employment markets and its desirable coastal setting have led to steadily increasing land costs. In 2001, Newport Beach was one of the ten California communities with the highest median home prices. This high market demand is manifest in a number of development issues facing the City, including development on odd - shaped or physically constrained properties, trends towards larger dwelling units, and proposals to allow residential development in commercial areas. Hundreds of dwelling units in coastal zone residential areas are rented for 30 days or less. The vast majority of these rentals occur during the summer when the demand for parking and City services is greatest. Overcrowding and public nuisances associated with these short-term rentals have resulted in adverse impacts to residential areas, coastal access, and coastal resources. Since 1992, the City has required short-term lodging permits to assist in controlling overcrowding and unruly behavior. Short-term lodging permits require the owner of the short-term rental to agree to limit overnight occupancy of the unit to a specific number of occupants not exceeding that permitted by the Building Code. Short-term rental owners are also required to use best efforts to insure that the occupants and guests are law abiding, do not create unreasonable noise or disturbances, or engage in disorderly conduct. Short-term rental owners are also required to use best efforts to insure compliance CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -33 with all health and sanitation regulations. Illegal or "bootleg" dwelling units exist in Newport Beach, experienced most often in the older, beach - oriented areas of West Newport, Balboa Peninsula, Balboa Island and Corona del Mar. These units are found in two typical forms: the "splitting" of a single dwelling unit into two separate occupancies, and the conversion of garages to living space. These units usually have a number of t health and safety code violations, due to conversion without proper building {�:""' ",' ""�`�•.. permits and inspections. Associated overcrowding, traffic congestion, and west Newlwrt homes illegal vehicle parking have also resulted in adverse impacts to residential areas and coastal resources. Illegal dwelling units are less prevalent than in the past, due to increased year -round owner occupancy in these areas and Report of Residential Building Records inspections that occur when properties are sold. A Report of Residential Building Records is a report issued by the City describing the zoning of the residential building, the number of dwelling units permitted pursuant to the zoning classification, and other information relevant to the use, occupancy and construction of the residential building. Policies: 2.7 -1. Continue to maintain appropriate setbacks and density, Floor area, and height limits for residential development to protect the character of established neighborhoods and to protect coastal access and coastal resources. 2.7 -2. Continue the administration of provisions of State law relative to the demolition, conversion and construction of low and moderate - income dwelling units within the coastal zone. 2.7 -3. Continue to authorize short-term rental of dwelling units pursuant to permits and standard conditions that ensure the rentals will not interfere with public access and enjoyment of coastal resources. 2.7-4. Continue to require Report of Residential Building Records inspections prior to the sale of residential properties to reduce and prevent violations of building and zoning codes by providing prospective owners of residential property with information as to permitted and illegal uses and construction. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2.34 2.8 Hazards and Protective Devices Coastal Act policies related to hazards and protective devices that are relevant to Newport Beach Include the following: 30235. Revelments, break waters, groins, harbor channels, seawalls, cliff retaining walls, and other such construction that alters natural shoreline processes shall be permitted when required to serve coastal -dependent uses or to protect existing structures or public beaches in danger from erosion and when designed to eliminate or mitigate adverse impacts on local shoreline sand supply. Existing marine structures causing water stagnation contributing to pollution problems and fishkills should be phased out or upgraded where feasible. 30253. New development shall: (1) "mize risks to life and property in areas of high geologic, flood, and fire hazard. (2) Assure stability and structural integrity, and neither create nor contribute significantly to erosion, geologic instability, or destruction of the site or surrounding area or in any way require One construction of protective devices that would substantially alter natural landforms along bluffs and cliffs. (3) Be consistent with requirements imposed by an air pollution control district or the State Air Resources Control Board as to each particular development. (4) Unirnize energy consumption and vehicle miles traveled. (5) Where appropriate, protect special communities and neighborhoods which, because of their unique characteristics, are popular visitor destination points for recreational uses. 30236. Channelizations, dams, or other substantial alterations of rivers and streams shall incorporate One best mitigation measures feasible, and be limited to (1) necessary water supply projects, (2) flood control projects where no other method for protecting edstng structures in the flood plain is feasible and where such protection is necessary for public safety or to protect existing development, or (3) developments where the primary function is the improvement of fish and wildlife habitat 2.8.1 General Newport Beach is susceptible to hazards, including, storm surges, beach and bluff erosion, landslides and slope failure, and wildland fires. Newport Beach is also susceptible to low - probability but high -risk events like earthquakes and tsunamis. It is the mandate of the Coastal Act to reduce potential risks to life and property and to avoid substantial alteration of natural Iandforms. In reviewing coastal development permits, the emphasis needs to be placed on siting and designing new development to avoid hazardous areas rather than relying on protective devices. Policies: 2.8.1 -1. Review all applications for new development to determine potential threats from coastal and other hazards. 2.8.1 -2. Design and site new development to avoid hazardous areas and minimize risks to life and property from coastal and other hazards. 2.8.1 -3. Design land divisions, including lot line adjustments, to avoid CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -35 hazardous areas and minimize risks to life and property from coastal and other hazards. 2.8.2 Tsunamis and Rogue Waves Tsunamis A tsunami is a sea wave caused by any large -scale disturbance of the ocean floor that occurs in a short period of time and causes a sudden displacement of water. Tsunamis can travel across the entire Pacific Ocean basin, or they can be local. Large -scale tsunamis are not single waves, but rather a long train of waves. The most frequent causes of tsunamis are shallow underwater earthquakes and submarine landslides; however, underwater volcanic explosions, oceanic meteor impacts, and even underwater nuclear explosions can also cause tsunamis. The highest elevation that the water reaches as it runs up on the land is referred to as wave runup, uprush, or inundation height. Inundation refers to the horizontal distance that a tsunami wave penetrates inland. The historical tsunami record for California suggests that the tsunami hazard in the Southern Califomia region, from the Palos Verdes Peninsula south to San Diego, is moderate. However, the Southern California historical record is very short and it is possible that Southern California has been impacted by tsunamis for which there is no record. More significantly, there are several active faults immediately offshore of the Southern California area, and any of these could generate a future earthquake that could have a tsunami associated with it. Finally, several submarine landslides and landslide - susceptible areas have been mapped offshore, within 3.5 to 14 km (2.2 8.7 mi) to of the coastline. For the Orange County coastline particularly, near -shore tsunamis should be considered worst -case scenarios, as these have the potential to cause high runups that would impact the coastline with almost no warning. The Channel Islands and Point Arguello protect Newport Beach from most distantly generated tsunamis (teletsunamis) spawned in the Pacific Ocean, except for those generated in the Aleutian Islands, off the coast of Chile, and possibly off the coast of Central America. Nevertheless, since the early 1800's, more than 30 tsunamis have been recorded in Southern California, and at least six of these caused damage in the area, although not necessarily in Newport Beach. Tsunamis generated in the Alaskan region take approximately 6 hours to make it to the Southern California area, while tsunamis generated off the Chilean coast take 12 to 15 hours to reach Southern California. Given those time frames, coastal communities in Southern California can receive adequate warning, allowing them to implement evacuation procedures. Alternatively, very little warning time, if any, can be expected from locally generated tsunamis. Locally generated tsunamis caused by offshore faulting or landsliding (including earthquake- induced landsliding) immediately offshore from CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -36 Newport Beach are possible, and these tsunamis have the potential to be worst -case scenarios for the coastal communities in Orange County. Modeling off the Santa Barbara coast suggests that locally generated tsunamis can cause waves between 2 and 20 m (6 to 60 feet) high, and that these could impact the coastline with almost no warning, within minutes of the causative earthquake or slump. The tsunami inundation maps were prepared based on several sea water levels scenarios for 100- and 500 -year tsunamis. The findings are summarized below: Tsunami Inundation at Mean Sea Level. In this scenario, Newport Bay and most of the harbor would be inundated with the potential to damage small vessels and docks. Some of the properties adjacent to the Bay would also be impacted, especially the northwestern section of Balboa Island, which is predicted to be inundated. The water level in Upper Newport Bay is anticipated to rise some but the data available are insufficient to quantify the hazard in this area. Tsunami Inundation at Mean High Water. In this scenario, Most of the harbor area, including the inland, developed portion of the Balboa Peninsula, Balboa Island, and Upper Newport Bay could be inundated during such an event. Near -shore sections of Lido Isle and Linda Isle would also be impacted, and Lido Isle would be cut off from the mainland due to Flooding along Newport Boulevard and 32nd Street. This scenario is expected to cause considerable damage to homes in the low -lying areas and to all moored boats. Tsunami Inundation at Extreme High Tide. In this scenario, a significant portion of Newport Harbor and the low -lying areas south of Coast Highway would be inundated by both the 100- and 500 -year wave runups. The 100 -year event shows that except for a small sliver of Lido Isle, the entire Newport Bay area would Flood. Flooding is also anticipated in the area where Newport Dunes Resort is located. In the 500 -year event, all of Lido Isle is expected to Flood. The probability of a tsunami occurring during extreme high tide is highly improbable and represents the worst -case scenario. However, these tsunami runups are possible if a tsunami occurs immediately offshore of Newport Beach, whether as a result of faulting or landsliding. Roque Waves Rogue waves are very high waves, as much as tens of meters high, but compared to tsunamis, they are very short from one crest to the next, typically less than 2 km (1.25 mi) long. Rogue waves arise unexpectedly in the open ocean and their generating mechanism is a source of controversy and active research. Some theories on rogue wave formation include: CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -37 • Strong currents that interact with existing swells making the swells much higher; • A statistical aberration that occurs when a number of waves just happen to be in the same place at the same time, combining to make one big wave; • The result of a storm in the ocean where the wind causes the water surface to be rough and choppy, creating very large waves. Rogue waves are unpredictable and therefore making planning nearly impossible. Nevertheless, some high waves that have historically impacted the Orange County coastline may be best explained as rogue waves. If this is the case, rogue waves have the potential to impact the Newport Beach area in the future. Policies: 2.8.2 -1. Review local and distant tsunami inundation maps for Newport Beach and adjacent coastal communities as they are developed to identify susceptible areas and plan evacuation routes. 2.8.2 -2. Participate in any regional effort to develop and implement workable response plans that the City's emergency services can adopt immediately for evacuation in the case of a tsunami warning. 2.8.2 -3. Prepare and deploy a system of tsunami detection and early warning systems. 2.8.2 -4. Include tsunami evacuation route information as part of any overall evacuation route sign program implemented in the City. Evacuation routes off of the peninsula and islands in the Bay should be clearly posted. An evacuation route traffic monitoring system that provides real -time information on the traffic Flow at critical roadways should be considered. 2.8.2 -5. Continue projects like the Surfside- Sunset/West Newport Beach Replenishment program to maintain beach width. Wide beaches provide critical protection against tsunami runup for structures along the oceanfront. 2.8.2 -6. Develop and implement a tsunami educational program for residents, visitors, and people who work in the susceptible areas. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -38 2.8.2 -7. Encourage the Newport-Mesa School District to include in their earthquake - preparedness curriculum information specifically related to the natural hazards that Newport Beach's citizens could face, and what to do about them. 2.8.2 -8. Support tsunami research in the Newport Beach offshore and Newport Bay areas. 2.8.3 Storm Surges and Seiches Two common coastal flooding processes include storm surges and seiches. Storm Surges A storm surge is an abnormal rise in sea water level associated with hurricanes and other storms at sea. Surges result from strong on -shore winds and /or intense low- pressure cells associated with ocean storms. Water level is controlled by wind, atmospheric pressure, existing astronomical tide, waves and swell, local coastal topography and bathymetry, and the storm's proximity to the coast. Most often, destruction by storm surge Is attributable to: Storm berth at The wedge • Wave impact and the physical shock on objects associated with the passing of the wave front. The water may lift and carry objects to different locations. • Direct impact of waves on fixed structures. This tends to cause most of the damage. • Indirect impacts, such as flooding and the undermining of major infrastructure (such as highways and railroads). Storm surges affect primarily ocean front property, and the low -lying areas of Newport Bay just inland from the jetties. Newport Bay is less affected by storm surge. Unlike tsunamis, which can occur anytime, storm surges are associated with bad weather. Given that during bad weather fewer people are expected to be CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -39 at the beach, storm surges are more likely to impact residents than tourists, and the potential number of casualties can be expected to be significantly less. The most common problem associated with storm surges is Flooding of low -lying areas, including structures. Coastal Flooding in Newport Beach occurred in the +# past when major storms, many of these r' ENSO (El Nino Southern Oscillation) events, impacted the area. This is often A_ 1� "". compounded by intense rainfall and strong winds. If a storm surge occurs during high tide, the Flooded area can be a _ significant. In the Southern California area, including Newport Beach, localized Balboa Peninsula houses destroyed by storm surge firom the Flooding and accelerated rates of coastal 1939 tropical storm erosion have occurred when storms are combined with high tides. This occurred during the 1977 -1978 storms, when the combination of high waves, local storm surges and high tides damaged several coastal structures in southern California. During the storms in 1988, the high water extended to the first row of houses behind the groin field at Newport Beach causing minor Flood damage to these structures. Storm surging associated with a tropical storm has been reported only once in the history of Newport Beach, in 1939. This suggests that the hazard of cyclone- induced storm surges has a low probability of occurrence. Nevertheless, the one incident in 1939 caused millions of dollars in damage to Newport Beach. Seiches A seiche is defined as a standing wave oscillation in an enclosed or semi - enclosed, shallow to moderately shallow water body or basin, such as lake, reservoir, bay or harbor. Seiches continue (in a pendulum fashion) after the cessation of the originating force, which can be tidal action, wind action, or a seismic event. Seiches are often described by the period of the waves (how quickly the waves repeat themselves), since the period will often determine whether or not adjoining structures will be damaged. The period of a seiche varies depending on the dimensions of the basin. Whether an earthquake will create seiches depends upon a number of earthquake - specific parameters, including the earthquake location (a distant earthquake is more likely to generate a seiche than a local earthquake), the style of fault rupture (e.g., dip -slip or strike - slip), and on the configuration (length, width and depth) of the basin. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -40 Amplitudes of seiche waves associated with earthquake ground motion are typically less than 0.5 m (1.6 feet high), although some have exceeded 2 m (6.6 ft). A seiche in Hebgen Reservoir, caused by an earthquake in 1959 near Yellowstone National Park, repeatedly overtopped the dam, causing considerable damage to the dam and its spillway. The 1964 Alaska earthquake produced seiche waves 0.3 m (1 ft) high in the Grand Coulee Dam reservoir, and seiches of similar magnitude in fourteen bodies of water in the state of Washington. Upper Newport Bay, the harbor and some of the reservoirs in Newport Beach could be susceptible to seiches. However, there is no record of seiches impacting the area after both local and distant earthquakes. Wind- generated seiches in Newport Bay also have not been reported. Due to the small surface area of Newport Bay and Upper Newport Bay, the probability that damaging seiches would develop in these bodies of water is considered low and are not considered a significant hazard in Newport Beach. If a seiche developed in Newport Bay, the waves are expected to be low, impacting primarily moored boats. Policies: 2.8.3 -1. Require all coastal development permit applications for new development on a beach or on a coastal bluff property subject to wave action to assess the potential for flooding or damage from waves, storm surge, or seiches, through a wave uprush and impact reports prepared by a licensed civil engineer with expertise in coastal processes. The conditions that shall be considered in a wave uprush study are: a seasonally eroded beach combined with long -term (75 years) erosion; high tide conditions, combined with long -term (75 year) projections for sea level rise; storm waves from a 100 -year event or a storm that compares to the 1982/83 El Nino event. 2.8.3 -2. Prepare and periodically update (every 5 years) comprehensive wave uprush and impact reports for shoreline and coastal bluff areas subject to wave action that will be made available to applicants for new development on a beach or coastal bluff property for use in fulfilling the requirement of Policy 2.8.3 -1 above. 2.8.3 -3. Develop and implement shoreline management plans for shoreline areas subject to wave hazards and erosion. Shoreline management plans should provide for the protection of private property, public improvements, coastal access, public opportunities for coastal recreation, and coastal resources. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -41 2.8.3 -4. Continue to utilize temporary sand dunes in shoreline areas to protect buildings and infrastructure from wave uprush, while minimizing significant impacts to coastal access and resources. 2.8.3 -5. Encourage the use of sand dunes with native vegetation as a protective device in beach areas. 2.8.3 -6. Encourage the use of non - structural methods, such as dune restoration and sand nourishment, as alternatives to shoreline protective structures. 2.8.4 Hurricanes and Tropical Storms Most hurricanes that affect the southern California region are generated in the southern portion of the Gulf of California. Though no hurricane - strength storms have reportedly hit the Los Angeles basin area in modern times, damage from wave swell and weather related to hurricanes that develop in the Baja California area has been reported throughout southern California. Swells caused by offshore storms and hurricanes in Baja California can cause localized flooding and erosion Half the Newport urf from the 1939 of the southern California coastline. tropicai storm rt Pier was destroyed by heavy s Only one tropical - strength storm has ever been recorded as actually hitting California. Near the end of September 1939, a tropical storm with sustained winds of 80.5 km /hr (50 mi /hr) came ashore at Long Beach. The storm generated five inches of rain in the Los Angeles basin on September 25th, and between 15 and 30.5 cm (6 and 12 inches) of rain in the surrounding mountains. In Newport Beach, this storm produced 30 -foot high waves (as high as a three -story building) that tore away half of Newport Pier and destroyed most of Balboa Pier, damaged portions of the jetties, several homes and small vessels, and caused numerous drownings. Other less severe but still significant storms that impacted the southern California coastline occurred during 1927, 1938- 1939, 1941, 1969, 1977 -1978, 1983, 1988 and even more recently in 1995, and 1997 -1998. Many of these wet winters have been associated with ENSO (El Nino Southern Oscillation) events. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -42 The main hazards associated with tropical cyclones, and especially hurricanes, are storm surge, high winds, heavy rain, Flooding, and tornadoes. The greatest potential for loss of life related to a hurricane for coastal communities is from the storm surge, which if combined with normal tides can increase the mean water level by 4.6 m (15 ft) or more. Waves that high would breach or extend over the Balboa Peninsula and impact all development adjacent to the coastline, including areas along Corona del Mar. 2.8.5 Sea Level Rise The level of the oceans has always Fluctuated with changes in global temperatures. The last ice age ended approximately eighteen thousand years ago, and since then the world has been experiencing global warming - most of the ice caps have melted, most of the glaciers have retreated, and the sea level has risen. Until about 5,000 years ago, sea level rose rapidly at an average rate of nearly 0.4 in (1 cm) a year. Since then, sea levels have continued to rise but at a slower pace. We are currently in an interglacial period, meaning "between glacial" periods, and as a result, sea levels are relatively high. However, during the last major interglacial period (approximately 100,000 years ago), temperatures were about 1 °C (2 °F) warmer than today and sea level was approximately 6 meters (20 feet) higher than today. Global sea level trends, therefore, have generally been estimated by combining the trends at tidal stations around the world. These records suggest that during the last century, worldwide sea level has risen 10 to 25 cm (4 to 10 inches), much of which has been attributed to global warming. Although sea level rise by itself does not cause substantial changes in the landform, several processes associated with sea level rise can have dramatic effects on our environment. For example, a significant rise in sea level would inundate coastal wetlands and lowlands, and the increased surges and swells associated with this rise in sea level would accelerate coastal erosion and exacerbate coastal Flooding, thereby threatening local structures and habitat. Other related processes include higher water tables, increased sea -water intrusion into fresh water aquifers, and increased salinity of rivers, bays, and aquifers. The warmer climate may also result in a much higher probability of extremely warm years with increased precipitation in some areas, and drought in other areas. It is clear that global changes in climate will occur, but the local impacts are still being debated. In fact, recent studies have moved away from the global doomsday predictions to predictions at the local scale. Much work yet needs to be done in this area. Previous studies suggest that a 1 m (39 in) rise in sea level would generally cause beaches to erode 200 to 400 m (650 to 1,300 ft) along the California coast. Given that the width of the beaches in Newport Beach varies between 15 and 190 m (50 and 600 ft), a sea level rise of as little as 15 cm (6 in) could have a negative impact CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -43 on the low lying areas around Newport Bay that are not protected by bulkheads and seawalls. Sea level rise would also cause increased sea -cliff retreat in the southern portion of the City where the beaches are narrow, and the surf pounds at the base of the bluffs, eroding away the soft bedrock that forms the cliffs. The record of sea level rise in the last century is poorly constrained in this region, however. Gauge records up and down the Pacific Coast show substantial variations in relative sea level rise. Based on the historical records from the two gauges closest to Newport Beach, in Los Angeles and San Diego, a 15 -cm rise in sea level in the Newport Beach area may take anywhere between 70 and 180 years, assuming that global warming does not accelerate in the next few decades. These estimates are too poorly constrained to engender policy changes and development of appropriate mitigation strategies. However, sea level rise would lead to the permanent inundation of low -lying areas, with potentially significant changes in land use, so it is not too soon to develop longer -term strategies that can be implemented to cope with these changes. 2.8.6 Coastal Erosion Beach Erosion Both natural processes and humans have modified the Newport Beach coastline extensively for over the past 180 years. The Balboa Peninsula did not begin to form until 1825. The wide sandy beaches that we associate with West Newport Beach are actually the result of shoreline stabilization programs that began as early as the 1920's, and beach sand nourishment programs that began in earnest in the 1960's. The "natural" beaches that characterized the southern California coastline prior to significant anthropogenic intervention were narrow strips of dry beaches on a sand - starved coast. These beaches would be unable to support the present -day demands for coastal access and recreation. In an undeveloped area, the availability of sand to replenish the beaches is dependent on floodwaters that bring sediment down from the mountains and into the littoral drift zone offshore. However, with the increase in dams and other flood control structures upstream, significantly less quantities of sediment reach the coast. Therefore, the sediments lost by natural near -shore processes are not being replaced. This is certainly the case in southern California, where most of the major streams have been dammed, or are lined in concrete, significantly reducing their sediment load. In the Newport Beach area, sand was historically delivered to the local beaches by the San Gabriel and Santa Ana Rivers, and to a limited extent, as a result of coastal bluff erosion. With the construction of dams and channelization of portions of the Santa Ana and San Gabriel Rivers, there was a substantial reduction in the volume of sediment reaching the coastline. Construction of harbors, jetties, CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -44 and other coastal barriers further reduced the amount of sand moved by along -shore currents. Beach sands occur from south of the Santa Ana River to the north entrance to Newport channel. Some of these deposits support dune vegetation, especially the sands forming the Balboa and Newport beaches. When the dune vegetation is well established, erosion of these sediments is minimal. However, foot or vehicular traffic and the burrowing action of rodents can easily compromise the health of this vegetation cover, exposing the near - Beach erosion in West Newport in the late 1960s surface sediments to erosion. Sand is easily transported during storms and can erode quickly if up -drift sand sources are cut off. The narrow beaches south of the channel entrance are especially vulnerable to high waves caused by tsunamis or storm surge. Beach erosion may be a problem south of the channel entrance due to the impedance of sediment redistribution via longshore flow by seawalls and rocky bluffs to the north. The area north of the jetties is also vulnerable to inundation due to low beach relief and erosion of coastal dunes (see Section 4.1.4 for dune habitat protection). Bluff Erosion South of the channel entrance to Newport Bay, to the south of the beach nourishment project area, the coastline is defined by steep coastal bluffs with a narrow basal wavecut platform that is covered by a thin veneer of beach sand. The bluffs form steep cliffs, especially at points. The Newport Beach coastal bluffs consist of siliceous marine shales, marine sandstone, and siltstone of the Monterey Formation. The sandstone beds are resistant and cliff forming, while the siltstone beds are less resistant and form steep talus- covered slopes. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -45 The bedrock of the Monterey Formation is folded, and dips primarily to the east, away from the bluff face. Overlying the Monterey Formation are Pleistocene marine terrace deposits. These deposits are massive to crudely bedded, consist of medium to coarse sand with a trace of pebble -sized gravel, and are friable and locally loose. A resistant shell bed marks the base of the terrace deposits. At the base of the bluffs is a mantle ■" "� "�� "''�� of colluvium. It consists of angular, Erosion acoasraiansdmto increasedwaW appicaoon pebble- to boulder -size clasts of sandstone and siltstone. In some areas, this colluvial cover buries the bluffs almost to the top, and in some areas, the material is reworked and forms a low terrace with weak soil development. The colluvium is heavily vegetated and appears to protect the base of the cliffs against normal wave action. The elevated 100,000 -year old marine terrace deposits are prone to landslides along steep cuts (such as those along Coast Highway) and are susceptible to significant erosion by stream incision, including rilling and gullying along bluff tops. Several streams are cutting through the coastal bluffs, forming steep narrow gorges and undermining the bluffs where they emerge along the coastline. The cap of marine terrace deposits overlying bedrock of the Monterey Formation is heavily rilled along stream cuts and along the face of the bluffs; so it is retreating faster than the underlying bedrock. The shaley and silty parts of the Monterey Formation is very fissile and fractured. Sliding and slumping of this unit appears to be the primary mechanism for current bluff retreat, with these processes occurring primarily along slopes that have been oversteepened by wave action (along rocky bluffs) or stream incisions. The more sandy parts of the Monterey Formation is the most resistant bluff- forming unit in the area. This geologic unit is prone to landsliding or mass wasting where undercut by wave action, especially at rocky bluffs or points, failing primarily as large blocks. A concern with urbanization of the bluff areas is that the bluff- forming materials become saturated when shallow ground water rises in response to the increased watering of lawns, generally in an attempt to grow non - native vegetation. Agricultural CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -46 irrigation, septic tanks and leach lines also contribute to the increased water content of these deposits. This over - watering increases the weight of the sediments, lubricates any joints or fractures that can act as planes of weakness, and increases the chemical dissolution of the underling rocks. All of these processes can contribute to slope instability along the bluffs. Artificial Coastal Protection The use of artificial coastal protection structures was favored 30 to 50 years ago, when the groin field in West Newport was constructed. Other structures intended to protect the coast, such as concrete and wooden seawalls and bulkheads, riprap and rock aprons are located in and around Newport Harbor and the adjacent shoreline. However, it has been long observed that where such protective structures extend seaward beyond adjacent unprotected lots, immediate Rock gran along Newport Beach erosion and notching may occur down drift, especially during large storms and periods of high tide. As beach sand levels fall, storm waves tend to converge on projecting structures (i.e. groins) and the waves refract toward unprotected areas of the beach. Therefore given that improperly located artificial protective devices can have negative impacts that far outweigh their benefits, beach nourishment has emerged as the preferred method of shoreline stabilization in recent decades. Structures built perpendicular to the shoreline tend to slow the long -shore drift of sediments and thus starve the down -drift area of beach - nourishing sediments. This is seen on a larger scale with the system of groins in the West Newport. The area east of the jetties has an erosional notch due to the blockage of littoral drift from the north. On a smaller scale, groins can have the same effect. In the case of West Newport Beach, eight rock groins were installed in the late 1960's and early 1970's to help maintain the beach. The effect of this groin field on the width of the beach is readily apparent (the beach on the northwest side of the groin field is wider than the beach where the groins are located). Southeast of the groin field, sand is being trapped by the west jetty at the harbor entrance, which stabilizes the Balboa Peninsula. The effect of these structures is complemented and augmented by regular beach sand replenishment. The protection of the beaches provides more than just a wider beach for recreational purposes and real- estate development; it serves as a buffer zone that provides protection from tsunami runup or storm surges, CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -47 especially in areas where there are no dune deposits in front of residential or commercial development. Erosion stabilization measures that have been implemented in the Corona del Mar area include concrete covering on one unstable slope, vegetation along the tops and bases of bluffs, boulders at the base of bluffs, where no colluvial cover exists, and channelization of the streams to prevent further downcutting of the terrace and bedrock units. Policies: 2.8.6 -1. Prepare and periodically update comprehensive studies of seasonal and long -term shoreline change, episodic and chronic bluff retreat, flooding, and local changes in sea levels, and other coastal hazard conditions. 2.8.6 -2. Continue to monitor beach width and elevations and analyze monitoring data to establish approximate thresholds for when beach erosion or deflation will reach a point that it could expose the backshore development to flooding or damage from storm waves. 2.8.6 -3. Develop and implement a comprehensive beach replenishment program to assist in maintaining beach width and elevations. Analyze monitoring data to determine nourishment priorities, and try to use nourishment as shore protection, in lieu of more permanent hard shoreline armoring options. 2.8.6 -4. Maintain existing groin fields and jetties and modify as necessary to eliminate or mitigate adverse effects on shoreline processes. 2.8.6 -5. Permit revetments, breakwaters, groins, harbor channels, seawalls, cliff retaining walls and other structures altering natural shoreline processes or retaining walls when required to serve coastal- dependent uses or to protect existing structures or public beaches in danger from erosion and when designed to eliminate or mitigate adverse impacts on local shoreline sand supply. 2.8.6 -6. Design and site protective devices to minimize impacts to coastal resources, minimize alteration of natural shoreline processes, provide for coastal access, minimize visual impacts, and eliminate or mitigate adverse impacts on local shoreline sand supply. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -48 2.8.6 -7. Discourage shoreline protective devices on public land to protect private property /development. Site and design any such protective devices as far landward as possible. 2.8.6 -8. Limit the use of protective devices to the minimum required to protect existing development and prohibit their use to enlarge or expand areas for new development or for new development. "Existing development' for purposes of this policy shall consist only of a principle structure, e.g. residential dwelling, required garage, or second residential unit, and shall not include accessory or ancillary structures such as decks, patios, pools, tennis courts, cabanas, stairs, landscaping etc. 2.8.6 -9. Require property owners to record a waiver of future shoreline protection for new development during the economic life of the structure (75 years) as a condition of approval of a coastal development permit for new development on a beach or shoreline that is subject to wave action, erosion, Flooding, landslides, or other hazards associated with development on a beach or bluff. Shoreline protection may be permitted to protect existing structures that were legally constructed prior to the certification of the LCR unless a waiver of future shoreline protection was required by a previous coastal development permit. 2.8.6 -10. Site and design new structures to avoid the need for shoreline and bluff protective devices during the economic life of the structure (75 years). Note: See Section 4.4.3 for Coastal bluff policies. 2.8.7 Geologic and Seismic Geologic The Newport Mesa and San Joaquin Hills areas of the City include slopes that are surficially unstable and can become a problem during intense or sustained rainfall. Many of the geologic units underlying these areas are also easily erodible. Cuts made into these high relief areas may be unstable if planes of weakness are exposed. In addition to posing a hazard to life and property, landslides and slope failure can impact traffic Flow along major routes, such as Coast Highway. Mudslides and debris Flows also have the potential to impact development at the mouths of canyons and at the base of the hills. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -49 Compressible soils are characteristic of areas underlain by poorly consolidated stream and colluvial deposits. These soils have a moderate to high potential for differential settlement when a large load, such as a building, is applied to them. Compressible soils underlie a significant part of the City. Areas of the City where compressible soils are most likely to occur are active and recently active stream channels, estuary deposits, beach and dune deposits, and young alluvial fan deposits. In the San Joaquin Hills, compressible soils are commonly found in canyon bottoms, swales, and at the base of natural slopes. Fine - grained soils, such as silts and clays, may contain variable amounts of expansive clay materials. These materials can undergo significant volumetric changes as a result of changes in moisture content. The upward pressure induced by the swelling of expansive soils can have significant harmful effects upon structures and other surface improvements. Thick soil profiles developed on the older marine deposits west of Newport Bay are typically clay -rich and will probably fall in the moderately expansive range. Potentially expansive bedrock may be exposed on natural slopes and ridges in the San Joaquin Hills, or may be uncovered by grading cuts made for developments. Man -made fills can also be expansive, depending on the soils used to construct them. Seismic The Newport- Inglewood fault extends across Newport Beach in a northwesterly direction. The southern portion of the City is underlain by the San Joaquin Hills fault, a recently discovered fault that does not extend to the surface but that could have associated, secondary faults at or near the surface. A major earthquake along any of these faults could result in substantial casualties and damage resulting in collapsed buildings, damaged roads and bridges, fires, flooding, and other threats to life and property. The San Joaquin Hills blind thrust was only discovered in the late 1990s and its geometry and behavior are not well constrained. However, an earthquake on this fault, due to its blind thrust geometry and location has the potential to be more damaging to Newport Beach than rupture of the Newport- Inglewood fault. Typically, earthquakes on thrust faults produce greater vertical accelerations than comparably sized strike -slip earthquakes (such as one on the Newport- Inglewood fault) and vertical motions are more damaging to structures. Scientists suggest the San Joaquin Hills blind thrust fault could produce a magnitude 6.8 to 7.3 earthquake. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -50 The Newport- Inglewood fault is considered the second most active fault in California. Prior to the discovery of the San Joaquin Hills fault, the Newport- Inglewood fault was thought to pose the greatest threat to Newport Beach because of its close proximity to the City, historic activity, and its recurrence interval. It runs from the City of Inglewood through Newport Beach where it extends out into the Pacific Ocean. This fault is capable of producing earthquakes in the range of 6.3 to 7.5 magnitudes. The 1933, 6.5 magnitude Long Beach earthquake occurred on the Newport- Inglewood fault, causing 120 deaths and severe damage. Unreinforced masonry buildings collapsed leaving people trapped beneath the rubble. Schools collapsed. The Long Beach earthquake epicenter was in the Newport Harbor area of Newport Beach. Buildings were damaged in the City as a result of this earthquake. The low population and development of the time attributed to decreased damage in the Newport Beach area. Damage to home and Park Avenue on g Balboa Island caused by the 1933 Long Beach earthquake The San Andreas fault is located approximately 70 miles northeast of the City. This fault is capable of producing earthquakes in the magnitude 8+ range. Current estimates are that major earthquakes on this fault occur approximately every 145 years. The last major earthquake on the Southern San Andreas fault occurred in 1857. The Whittier fault is the northern extension of the Elsinore fault and is located approximately 20 miles north of the City. No major historical earthquakes have been attributed to the Whittier fault. However, trenching studies have documented recurrent movement of this fault in the last 17,000 years. The Southern California Earthquake Center determined there is a five percent chance of an earthquake occurring on the Whittier fault by 2024. The Whittier fault is thought capable of producing a magnitude 6.8 maximum magnitude earthquake, although some investigators propose an even larger magnitude 7.1 quake. In addition to the four fault systems mentioned above, there are several other known potential sources of strong ground shaking within 60 miles of Newport Beach. These include the Peralta Hills, Santa Monica - Hollywood, Puente Hills and Cucamonga faults. These faults could also affect Newport Beach, though not as severely. There are still many uncharted earthquake faults throughout California and several active offshore faults posing possible impacts for Newport Beach. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -51 Poorly consolidated sediments and shallow groundwater underlie portions of Newport Beach, particularly from West Newport to the tip of the Balboa Peninsula and in the areas in and around Newport Bay. These areas have a high susceptibility to liquefaction during earthquakes. Liquefaction is a geologic process that causes various types of ground failure. When liquefaction occurs, the sediments involved have a total or substantial loss of shear strength, and behave like a liquid or semi - viscous substance. Liquefaction can cause structural distress or failure due to ground settlement, a loss of bearing capacity in the foundation soils, and the buoyant rise of buried structures. The excess of hydrostatic pressure generated by ground shaking can result in the formation of sand boils or mud spouts, and /or seepage of water through cracks. The areas with the liquefaction potential are densely populated and possess considerable commercial property. It is likely that a nearby moderate to strong earthquake will cause extensive damage to buildings and infrastructure. Newport Beach requires the properties in these areas to be built on compacted soils, which should lessen the liquefaction potential. Other secondary affects of earthquakes include: ■ Fires. A high probability of fire following an earthquake results from the number of broken gas lines typically occurring during shaking. Water mains and lines often break as well, due to ground movement. The combination of fires and a water shortage seriously complicates the response to earthquakes and their secondary affects. • Dam Failure. Flooding caused by earthquake induced dam failure of the Prado Dam could impact Newport Beach. However, the probability of Flooding due to dam failure is low since the Prado Dam is rarely full. Flooding could also result from the failure of the Big Canyon Reservoir. ■ Hazardous Chemical Spills. The north end and west side of the Newport Beach house a large percentage of the City's industries with large quantities of hazardous chemicals. This area would be most affected by hazardous chemical spills and hazardous chemical fires resulting from earthquakes. ■ Oil Spills and Pipeline Breakage. Oil fields and oil storage tanks can be seen on the west side of Newport Beach. Although the tanks are diked, a major earthquake could damage the tanks and dikes causing vast amounts of oil spillage. There are numerous underground pipelines traversing the City. An earthquake could easily cause a pipeline breakage, releasing either natural crude oil or refined petroleum products. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -52 Policies: 2.8.7 -1. Conduct hydrological studies of Big Canyon, Buck Gully and Morning Canyon to develop methods to control water quality, sedimentation, erosion, and slope failure and to protect downstream areas from debris Flows. 2.8.7 -2. Require new development to provide adequate drainage and erosion control facilities that convey site drainage in a non - erosive manner in order to minimize hazards resulting from increased runoff, erosion and other hydrologic impacts to streams. 2.8.7 -3. Require applications for new development, where applicable [i.e., in areas of known or potential geologic or seismic hazards], to include a geologic /soils /geotechnical study that identifies any geologic hazards affecting the proposed project site, any necessary mitigation measures, and contains a statement that the project site is suitable for the proposed development and that the development will be safe from geologic hazard. Require such reports to be signed by a licensed Certified Engineering Geologist or Geotechnical Engineer and subject to review and approval by the City. 2.8.7 -4. Continue to regularly update building and fire codes to reflect the best available standards for seismic safety design. 2.8.8 Fire 1993 Laguna Canyon fire advancing towards Newport Beach Due to its weather, topography and native vegetation, the entire southern California area is at risk from wildland fires. The extended droughts characteristic of California's Mediterranean climate result in large areas of dry vegetation that provide fuel for wildland fires. Furthermore, the native vegetation typically has a high oil content that makes it highly flammable. The area is also intermittently impacted by Santa Ana winds; the hot, dry winds that blow across southern California in the CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -53 spring and late fall, often igniting and /or spreading fires. Combine these conditions with the fact that more people than ever are living and playing in wildland areas, and the potential for major wildland fires to occur increases even further. Fires usually last only a few hours or days, but their effects can last much longer. An intense wildland fire may destroy all the vegetation. The fire also destroys most of the roots that hold the soil in place, allowing running water to wash the soil away. In addition, the organic material in the soil may be burned away or decompose into water - repellent substances that prevent water from percolating into the soil. As a result, even normal rainfall can cause exceptional erosion, Flooding and debris Flows from a burned area. The 1993 Laguna Canyon wildland fire burned 17,000 acres, destroyed 366 homes, and forced the evacuation of Laguna Beach's 24,000 residents. In 1997, wildland fires charred many areas of southern California, leaving them barren before the next winters heavy El Nino rainfall. Of the 25 large southern California wildland fires that occurred that year, ten produced debris Flows after the first major winter storm, and Flooding plagued eight other areas. Only four burn areas showed little erosion or runoff. Flood control facilities may be severely taxed by the increased Flow from the denuded hillsides and the resulting debris that washes down. Recreation areas that have been affected may also be forced to close or operate at a reduced scale. In addition, the buildings that are destroyed by fire are usually eligible for reassessment, which reduces income to local governments from property taxes. In the aftermath of the 1993 Laguna Canyon fire, Newport Beach fire officials, in cooperation with federal, state, county, and other local officials, began analyzing the conditions that allowed this fire and others to occur. The areas at greatest risk of wildland fires are homes and structures in and around the urban wildland interface areas. These areas include lower Buck Gully, Morning Canyon, the mouth of Big Canyon, and Spyglass Canyon. Newport Beach employs two different Homes adjaceot to Buck GNly methods for reducing the risk of fire in these urban wildland interface areas: hazard reduction and fuel modification. Both methodologies use the principle of reducing the amount of combustible fuel available, which reduces the amount of heat, associated Flame lengths, and the intensity of the fire that would threaten the adjoining structures. Hazard reduction CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -54 reduces the amount of fuel within 100 feet of any structure, thus creating a defensible space used to slow the rate and intensity of an advancing wildfire and to create an area for firefighters to suppress the fire and save the structure. Fuel modification zone establishes a ribbon of land surrounding the homes designed to diminish the intensity of a wildfire as it approaches the homes. A fuel modification zone differs from a hazard reduction zone through a combination of methodologies, including the removal of native vegetation replaced with fire resistive plant species, as well as the reduction of amount of native combustible vegetation. In addition to reduction of the vegetation hazards, areas regulated by fuel modification requirements are also required to "harden" the structures immediately adjacent to the wildland area. This "hardening" is done by providing automatic fire sprinkler protection, installation of class "A" roof assemblies, installation of dual glazed windows, one -hour fire resistive construction on sides of the structure facing the wildland area, and the elimination of any combustible exterior structural elements, such as patio covers. Policies: 2.8.8 -1. Apply hazard reduction, fuel modification, and other methods to reduce wildfire hazards to existing and new development in urban wildland interface areas. 2.8.8 -2. Site and design new development to avoid the need to extend fuel modification zones into sensitive habitats. 2.8.8 -3. Use fire- resistive, native plant species from the City- approved plant list in fuel modification zones abutting sensitive habitats. 2.8.8 -4. Prohibit invasive ornamental plant species in fuel modification zones abutting sensitive habitats. 2.8.8 -5. Continue to maintain a database of parcels in urban wildland interface areas. 2.8.8 -6. Continue annual inspections of parcels in the urban wildland interface areas and, if necessary, direct the property owner to bring the property into compliance with fire inspection standards. 2.8.8 -7. Continue to regularly update building and fire codes to reflect the best available standards for fire safety design.

Wherever appropriate and feasible, public facilities, including parking areas or facilities, shall be distributed throughout an area so as to mitigate against the impacts, social and otherwise, of overcrowding or overuse by the public of any single area. 30252. The location and amount of new development should maintain and enhance public access to the coast by (1) facilitating the provision or extension of transit service, (2) providing commercial facilities within or adjoining residential development or in other areas that will minurize the use of coastal access roads, (3) providing nonautomobile circulation within the development, (4) providing adequate parking facilities or providing substitute means of serving the development with public transportation, (5) assuring the potential for public transit for high intensity uses such as high-rise office buildings, and by (6) assuring that the recreational needs of new residents will not overload nearby coastal recreation areas by correlating the amount of development with local park acquisition and development plants with the provision of onsite recreational facilities to serve the new development 2.9.1 Public Transit The City's Transportation Demand Management Ordinance requires new nonresidential developments that are estimated to employ 100 or more employees to reduce the number of peak - period vehicle trips, promote and encourage the use of alternative modes of transportation, and provide support facilities for alternative modes of transportation. Bus Transportation Public transportation services in Newport Beach are provided by the Orange County Transportation Authority District (OCTA) and consist of regular fixed -route service. OCTA operates the Newport Beach Transportation Center at Avocado and San Joaquin Hills Road. Demand for bus service from the inland areas to Newport Beach is intensified during the summer peak months. OCTA adds buses to beach routes most in demand to offset the increased load. The City's Subdivision Code provides for the dedication of transit facilities, such as bus turnouts, benches, shelters and similar facilities, by new development. The City's Public Works Department coordinates with OCTA on the location of transit facilities.

CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -57 2.9.2 Bikeways and Trails Newport Beach provides an extensive system of bikeways and trails to serve bicyclists, equestrians, and pedestrians (see Bikeways and Trails Map). In addition to providing coastal access and recreational opportunities, these bikeways and trails also facilitate alternative modes of transportation. Policies: 2.9.2 -1. Maintain, expand, and encourage the use of bikeways and trails as alternative circulation routes. 2.9.2 -2. Continue to cooperate with state, federal, county and local agencies to coordinate bikeways and trails throughout the region. 2.9.2 -3.

Note: See Section 3.1 for public access policies. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -58 2.9.3 Parking Parking in the coastal zone is a major issue in Newport Beach. Surveys indicate that the current supply is generally adequate in the winter for both residents and visitors. During the summer the demand for parking increases. During peak summer weekends, parking demand associated with beach and bay uses is virtually unlimited. Commercial All of the commercial areas in the coastal zone were originally developed at a time when little or no off -street parking was required. Therefore, a number of properties do not conform to current off -street parking requirements. In many coastal zone commercial areas, commercial parking demand is accommodated by on -street parking spaces and in public lots. This has created conflicts between commercial uses, residential uses, and coastal zone visitors. The City's off -street parking regulations are consistent with other coastal communities and are adequate to meet land use demands. Therefore, new development will be required to provide adequate off -street parking. The coastal zone's main commercial areas were studied during the summer of 2002 to determine if there is adequate parking. Field observations and analysis were conducted to inventory and review current parking conditions. A forecast of future parking adequacy was also conducted using a parking analysis model. West Newport commercial K West Newport. West Newport is a commercial strip on the north side of West Coast Highway between the Semeniuk Slough and the city limits. Of the 258 parking spaces, there are slightly more private off -street spaces (57 %) than public on -street spaces. There are also 174 public spaces on the south side of West Coast Highway in the West Newport Park lots and on Seashore Drive. The 2002 field observations indicate there is adequate parking on the north side of West Coast Highway to meet land use demands. Public spaces along the CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -59 south side were occupied with residential vehicles in the early morning and were replaced with beach traffic in the afternoon until the evening when residential vehicles returned. The parking analysis model indicates that parking in this area should be adequate to accommodate demand. Beach users mainly use the parking on the south side and it is anticipated that none of these spaces are needed to serve demand from the north side of the highway. Mariner's Mile. The Mariner's Mile commercial area is located on Coast Highway between Newport Boulevard and Dover Drive. Marine - related, visitor serving, and entertainment businesses dominate the Mariner's Mile waterfront. Therefore, most coastal zone visitors in this area are patrons of these businesses. The vast majority (87 %) of 3,245 parking spaces in Mariner's Mile are private spaces designated for use by business patrons. The 2002 field observations indicate there is adequate parking during daytime hours, but that parking facilities reach effective capacity during evening hours, due to the concentration of restaurants and entertainment establishments. The parking analysis model indicates that a parking shortage should be experienced in the Mariner's Mile area during the weekday midday hours. This discrepancy with the 2002 field observations indicate that the area is experiencing a higher than normal amount of multi- purpose trips, and /or trips by alternative mode than estimated in the parking requirements or that some land uses may not be open during the weekday midday hours as anticipated in the parking estimates. Balboa Peninsula. Lido /McFadden includes the Lido, Civic Center, Cannery Village, and Newport Pier commercial areas. The majority (56 %) of 5,393 parking spaces in Lido /McFadden are in public lots and on- street. In Balboa Village, the vast majority (73 %) of 1,267 parking spaces are in public lots and on- street. The 2002 field observations indicate that on both weekdays and weekends, public lots are used more heavily than any other type of parking and private lots have the lowest occupancy. Parking analysis indicates parking shortfalls in both Lido/McFadden and Balboa Village. Balboa Pier parking lot CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -60 Marine Avenue. Marine Avenue is a retail district on Balboa Island that is popular with residents and coastal zone visitors. Of the 134 parking spaces, there are slightly more public on -street spaces (57 %) than private off -street spaces. The 2002 field observations indicate that parking is routinely at or above capacity and that parking demand extends well beyond the blocks immediately surrounding the business area. Marine Avenue on Balboa Island The model indicates a significant latent demand for parking in this area. The density of development along Marine Avenue and the pedestrian- oriented character of the development create a unique condition in this area. Land uses in the area generate trips with a much higher than normal amount of multi - purpose stops. In addition, many of the existing land uses cater to the needs of the local residents who walk to and from the sites, as well as to visitors. Therefore, the actual parking demand is less than the model is predicting. However, the demand is still much higher than the current supply. Corona del Mar. Corona del Mar is a commercial strip along East Coast Highway between Avocado Avenue and Hazel Drive. Only the south side of this commercial area is located within the coastal zone. The vast majority (88 %) of 2,031 parking spaces in Corona del Mar are private spaces designated for use by business patrons. The 2002 field observations indicate there is adequate parking to meet land use demands. The parking analysis model indicates that existing supply is more than adequate for the existing uses. Overestimated demand may be caused by a higher than expected number of multi - purpose trips or differences in the anticipated split of modes of transportation. Because of the amount of private parking in this area versus public spaces, it is less likely to have a large amount of shared parking occurring because of temporal differences in parking demand. Residential Most of the residential areas in the coastal zone were also developed at a time when there was little need for automobile parking. However, unlike commercial areas, high market demand has resulted in continual remodeling and reconstruction of residential properties. New dwelling units and remodels resulting in an increase in CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -61 the number of habitable rooms are required to meet current off -street parking requirements. Street pxkig on the Balboa Pemstla Policies: While remodels and reconstruction have increased the amount of off -street parking, parking problems continue in coastal zone residential areas. Residential dwelling units with nonconforming parking continue to exist. Also, some garages are used for purposes other then parking, including storage, office space, or living areas. The popularity and demographics of the coastal zone sometimes leads to dwelling units with more people and automobiles than in inland areas. Illegal dwelling units also add to parking demand. Finally, some people simply prefer to use curbside parking due for convenience, particularly in areas where garages are accessed via narrow alleys. As a result, a significant number of coastal zone residents use public street parking or public lots instead of private off -street parking. 2.9.3 -1. Site and design new development to avoid use of parking configurations or parking management programs that are difficult to maintain and enforce. 2.9.3 -2. Continue to require new development to provide off -street parking sufficient to serve the approved use in order to minimize impacts to public on -street and off -street parking available for coastal access. 2.9.3 -3. Continue to require off -street parking in new development to have adequate dimensions, clearances, and access to insure their use. 2.9.3 -4. Continue to require properties with nonconforming parking to provide code - required off -street parking when new uses, alterations or additions result in increased parking demand. 2.9.3 -5. Approve no application for a modification or waiver of off -street parking requirements that are found to impact public parking available for coastal access. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 2 -62 2.9.3 -6. Continue to require new development to minimize curb cuts to protect on- street parking spaces. 2.9.3 -7. Continue to require alley access to parking areas for all new development in areas were alley access exists. 2.9.3 -8. Provide incentives to encourage lot consolidation where lots are of insufficient size to accommodate on -site parking and sufficient commercial intensity of development. 2.9.3 -9. Encourage commercial and institutional development located near beaches and other coastal resources to provide parking for public access during weekends and holidays. 2.9.3 -10. Develop parking management programs for coastal zone areas that achieve the following: • Provides adequate, convenient parking for residents, guests, business patrons, and visitors of the coastal zone; • Optimizes use of existing parking spaces; • Provides for existing and future land uses; • Reduces traffic congestion; ■ Limits adverse parking impacts on user groups; ■ Provides improved parking information and signage; ■ Generates reasonable revenues to cover City costs; ■ Accommodates public transit and alternative modes of transportation. 2.9.3 -11.

Newport Beach has developed an extensive system of access to ocean beaches and the bay (see Coastal Access Map). Virtually all of the Pacific Ocean shoreline beaches are public and the bay is accessible via public beaches, parks, shoreline trails, walkways and boardwalks. The City will continue to require all new development, causing or contributing to adverse public access impacts, to provide easements or dedications in areas where public access is inadequate. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -1 Pacific Ocean Beaches West Newport/Balboa Peninsula. West Newport and the Balboa Peninsula have over 5 miles of wide, sandy beaches. Vertical access to these beaches is provided by 89 street ends, which occur every 200 to 500 feet. The Oceanfront Boardwalk runs along the beach for approximately 3 miles from 3e Street in West Newport to F Street on the Peninsula. This multi -use concrete walkway is 12 to 22 foot wide and is popular with pedestrians, bicyclists, and skaters. OceaMront Boardwalk at 15' Street Corona del Mar. City- operated Corona del Mar State Beach (Big Corona) is a half mile -long sandy beach located southerly of the Newport Harbor entrance. Vertical access to this beach is provided by an access road near the intersection of Ocean Boulevard and Jasmine Avenue and by walkways at Lookout Point and Inspiration Point view parks on Ocean Boulevard. Little Corona Beach is a small sandy cove with rocky intertidal platform reefs. The Newport Beach Marine Conservation Area is offshore. Vertical access is provided by a walkway at Poppy Avenue (Glen Drive). The Newport Beach Marine Conservation Area contains natural habitats and the provision of additional public access on Little Corona Beach must be consistent with the protection of these resources. Big Corona CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -2 Lower Newport Bav /Harbor West Newport/Balboa Peninsula. The Lower Bay shoreline of West Newport and the Balboa Peninsula consist of relatively narrow sandy beaches and bulkheads. There are 89 street ends that provide vertical access to Lower Newport Bay, including The Rhine, Newport Island, Rialto, and Rivo Alto channels. Most street ends provide a small beach and shore moorings. Larger public beaches are located at Las Arenas Beach (16°i -19°' Street), 10" Street Beach, MonterO Beach Las Arenas Beach (Island Avenue to Medina Way), and N Street Beach. Small public beaches are also located at Channel Place Park and Newport Island Park. There is also a 0.65 -mile bayfront walkway that extends from Main Street in Balboa Village to 7"' Street. Waterfront commercial areas also provide vertical and lateral access to Lower Newport Bay. Commercial developments in Lido Village, Cannery Village, McFadden Square, and Balboa Village and on the Lido Peninsula provide public access easements to and along the waterfront. In most cases, these easements have been integrated into the project's design, such as restaurants with outdoor waterfront dining areas and boarding areas for charter and excursion vessels. New development will present additional opportunities to extend and enhance waterfront access in these areas. Particular attention should be given to extending the Lido Marina Village boardwalk across all of the waterfront commercial properties in Lido Village and to provide a continuous waterfront walkway along the Rhine Channel to connect the Cannery Lido Manna Village doardwark Village and McFadden Square waterfront commercial areas with Las Arenas Beach at 19°i Street. A connection from Lido Village to Mariner's Mile should also be provided, if feasible. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -3 Mariner's Mile. The Mariner's Mile is a commercial area with a shoreline consisting of bulkheads. Commercial and institutional developments in Mariner's Mile provide public access easements to and along the waterfront. Although the easements are fragmented, with new development, there is an opportunity to provide a continuous waterfront walkway from the Coast Highway /Newport Boulevard Bridge to the Balboa Bay Club. Bayside. The Bayside area shoreline Mariners Mile consists mainly of bulkheads, with a few small beaches. Beacon Bay Beach (Lot 1) is accessible from Beacon Bay Drive via walkways at the Cape Cove, Shelter Cove, and Reef Cove Street ends. Bayside Drive County Beach is accessible from Bayside Drive via the Orange County Harbor Patrol facility. Lateral access to Promontory Bay is provided by a walkway along Bayside Drive and a public access easement along the bulkhead adjacent to Newport Manna Apartments. This public access easement connects to a quarter mile walkway on a floating dock in the Balboa Island Channel. Lateral access is also provided around the Balboa Yacht Basin. Corona del Mar. Corona del Mar's bayside shoreline is at the harbor entrance and is characterized by high coastal bluffs with a few small sandy coves. China Cove is accessible from Cove Street and Shell Street. Rocky Point (Pirate's Cove) is accessible by a trail at Lookout Point on Ocean Boulevard and Corona del Mar State Beach. There is also a small pocket park in an unnamed street end off of the 2300 block of Bayside Drive that provides access to Carnation Cove. Lido Isle. On Lido Isle, vertical access to the Lower Bay is provided by walkways within 13 street end easements. These street ends are leased to Lido Isle Association with the condition that the association maintain and operate all walkways in a manner that allows for open public access. There are also public beaches at Via Pirate's Cove Genoa (Parcel B) and at Via Trieste (Parcel C). CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -4 Balboa Island. All of Balboa Island's beaches are public. There are 33 street ends that provide vertical access and the Bay Front Boardwalk that circles the island enhances lateral access. There are also 4 street ends that provide access to the Grand Canal. Upper Newport Bay The Upper Newport Bay is coastal wetlands bordered by 40 to 100 -foot high bluffs. Most of the Upper Newport Bay area is in the Upper Newport Bay Marine Park. Due to the steep coastal bluffs and high number of sensitive environmental resources within the marine park, access is more restricted than other coastal areas. Still, ample public access is available. The 752 -acre Upper Newport Bay Marine Park preserves one of the largest coastal upper Newport Bay Marine Park wetlands in Southern California. In addition to protecting its diverse habitats, the marine park provides canoe, kayak, and walking tours. Shellmaker Island in the marine park serves as a staging area for tours of the Upper Newport Bay. Shellmaker Island is only open to the public when programs and tours are scheduled and is accessible from Back Bay Drive. The marine park is also accessible from University Drive and Back Bay Drive. The Upper Newport Bay Nature Preserve is located on the bluffs on the north and northwest sides of the Upper Newport Bay Marine Park. This 140 -acre regional park provides hiking, bike, equestrian trails to and along the marine park. The Upper Newport Bay Nature Preserve is accessible from University Drive and Bayview Way. Access to and along the Upper Newport Bay is also provided by Back Bay Drive, a 3.5 -mile multi - model road that runs along the base of the bluff on the easterly side of the bay. Back Bay Drive begins at Jamboree Road and ends at East Bluff Drive, where it connects with a trail that continues west of Jamboree Road and along San Diego Creek into central Orange County. The Lookout at Bads Bay Drive CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -5 the corner of Back Bay Drive and East Bluff Drive serves as a staging area for tours of the bay. On the west side of the bay, access is provided via North Star Beach. North Star Beach has a sandy beach and is the site of the Newport Aquatics Center, a public recreation and launching facility. North Star Beach is accessible from White Cliffs Drive, off of Polaris Drive. The area north of the Newport Aquatics Center contains natural habitats and the provision of additional public access in this area must be consistent with the protection of these resources. On the east side of the bay, access is provided by Big Canyon Nature Park. Big Canyon Nature Park is a passive open space area that provides hiking trails from Jamboree Road to the Upper Newport Bay Marine Park. The mouth of Big Canyon contains natural habitats and the provision of additional public access must be consistent with the protection of these resources. Semeniuk Slouch Semeniuk Slough, also referred to as the Oxbow Loop, is a coastal salt marsh. The slough is accessible via 9 street ends in Newport Shores and the Newport Shores View Park. The provision of public access must be consistent with the protection of the adjacent natural resources. semmiuk SIM0 CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -6 Policies: 3.1.1 -1.

The City Council finalized this policy with the adoption of _ Resolution No. 91 -80 on July 11, 1991. This policy established conditions and restrictions on the nature and extent of these improvements and a mitigation program involving the reconstruction of West Newport street end 33 unimproved street ends between 36th Street and Summit Street to provide additional parking and improved public access. In 2002, the final five street ends were reconstructed. Pursuant to the mitigation program, a minimum of 85 percent of the encroachment fees will be used for the construction and maintenance of improvements which directly benefit the beach - going public such as parking spaces, restrooms, vertical or lateral walkways along the beach and similar projects. Policies: 3.1.3 -1. Continue to maintain and improve the Oceanfront public right -of -way for public access purposes. 3.1.3 -2.

Prohibit any encroachments that impact public access, recreation, views and /or coastal resources. E. Require landscaping to be designed and maintained to avoid impacts to public access and views. F. Restrict landscaping in dune habitat areas to native vegetation. 3.1.3 -5. Require annual renewal of encroachment permits and a fee. 3.1.3 -6. Require encroachment permits to specify that the property owner waives and gives up any right to contest the validity of the oceanfront street easement, and that the encroachment permit is revocable, without cause, if the City proposes to construct public improvements within that zone. 3.1.3 -7. Require encroachment permits to specify that the construction of any seawall, revetment or other erosion control devices, if necessary, shall occur within, or as close as feasible to, private property. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -14 3.1.3 -8. Incorporate into the implementation plan regulations specifying the types of improvements permitted within encroachment zones, a prohibition on improvements that could impair or restrict public access or views, procedures for the encroachment permit applications, City administration of the policy, and other appropriate provisions. 3.1.3 -9. As mitigation for any impact on beach access resulting from the encroachments: A. Maintain 33 street ends between 36th Street and Summit to provide an average of 2 parking spaces per street. B.

At least one handicapped parking space shall be designated at the Orange Avenue street end and at least one other handicapped parking space at one other West Newport street end. D. Require a minimum of 85 percent of the fees generated by encroachments will be used for the construction and maintenance of improvements which directly benefit the beach -going public such as parking spaces, restrooms, vertical or lateral walkways along the beach and similar projects. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -15 3.1.4 Bay /Harbor Encroachments Shore connected structures, such as piers, Floats, and bulkheads have long been permitted in the bay and harbor. Newport Beach, in conjunction with Federal, State, and County agencies, has established a set of Harbor Lines to define bayward limits for various types of structures. Harbor Lines and other regulations were originally established to insure navigable channels and safe harbor operations and to minimize conflicts with adjacent properties. However, such regulations are increasingly used as a means of protecting public views and public access. Policies: Resider ial piers 3.1.4 -1. Continue to regulate the construction of bay and harbor structures within established Bulkhead Lines, Pierhead Lines, and Project Lines. 3.1.4 -2. When applicable, continue to require evidence of approval from the County of Orange, Coastal Commission, U.S. Army Corps of Engineers, and other resource management agencies, prior to issuing permits. 3.1.4 -3. Design and site piers, including remodels of and additions to existing piers so as not to obstruct public lateral access and to minimize impacts to coastal views and coastal resources. 3.1.4 -4. In residential areas, limit structures bayward of the bulkhead line to piers and floats. Limit appurtenances and storage areas to those related to vessel launching and berthing. 3.1.4 -5. Encourage the joint ownership of piers at the prolongation of common lot lines as a means of reducing the number of piers along the shoreline. 3.1.4 -6. Continue to prohibit private piers at street ends. 3.1.4 -7. Design and site bulkheads to protect the character of the existing shoreline profiles and avoid encroachment onto public tidelands. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -16 3.1.5 Private /Gated Communities Throughout Southern California, access to the shoreline is restricted to the public due to private residential communities. Exclusive gated communities in some cases totally circumvent public access to the shoreline. Such communities present a major issue in terms of protecting, expanding, and enhancing coastal access. Most of the shoreline in Newport Beach is publicly owned and accessible. However, there are a few private residential communities that impede public access to and along the shoreline. These communities are Balboa Coves, Bay Island, Bayshores, Bayside Place, Collins Island, De Anza Bayside Village, Linda Isle, and Harbor Island. Some of these communities are on small private islands. They do not impede access to public beaches, coastal parks, trails, or coastal bluffs; however, they do block public access to and along their immediate shoreline. Balboa Coves, Bayside Place, Bayshores and De Anza Bayside Village are on the mainland, but are situated so as not to block public access other than to their immediate shoreline. In all of these areas, the shoreline consists mainly of bulkheads with a few small and isolated sandy beaches. Balboa Coves. Balboa Coves is a 68 -lot single - family gated community located on the Newport Island Channel southwest of the Newport Boulevard /Coast Highway Bridge. The community is accessible from Coast Highway via Balboa Coves, a private street. The shoreline is on the south side of the community and consists of a series of manmade coves with narrow sandy beaches. Bay Island. First developed around 1904, Bay Island is a 25 -unit (currently developed with 24 units, including one caretaker's unit) single family cooperative on a private island in the Newport Channel. A gated pedestrian bridge at the end of Island Avenue connects Bay Island with the Balboa Peninsula. Motor vehicles are prohibited on the island. Off -street parking for residents is provided at a 48 -space parking structure located at 501 West Bay Bay Island Avenue. The shoreline consists mainly of bulkheads, with the exception of the east side of the island, which has a relatively wide sandy beach. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -17 Bayshores. Developed in 1941, Bayshores is a 258 -lot single - family gated community located on the Lido Channel southwest of the Coast Highway /Newport Bay Bridge. The 39 -unit Anchorage Apartments is also located within the community. The community is accessible from Coast Highway via Bay Shores Drive, a private street. The shoreline is on the south and east sides of the community and consists of bulkheads and two small sandy beaches. Bayside Place. Bayside Place is a 7 -lot single - family gated community located off of the 2300 block of Bayside Drive. The community is accessible from Bayside Drive via Bayside Place, a private street. The shoreline (Carnation Cove) consists of bulkheads and rocky beaches. Public access to the shoreline is available at an adjacent street end pocket park. Collins Island. Created in 1906, Collins Island is a 7 -lot single - family community on a private island in the Balboa Island Channel. A gated bridge at the end of Park Avenue connects Collins Island with Balboa Island. The shoreline consists of bulkheads. De Anza Bayside Village. De Anza Bayside Village is a 343 -space mobile home park located on the Upper Newport Bay adjacent to the Newport Dunes. The community is accessible to Bayside Drive via Bayside Way, a private street. The shoreline is on the north side of the community and consists of bulkheads and a small sandy beach at the community center. The community includes the undeveloped De Anza / Bayside Marsh Peninsula. Harbor Island. Developed in 1926, Harbor Island is a 35 -lot single - family community on a private island located between Linda Isle and Collins Island. A gated bridge connects Harbor Island to the mainland at the end of Harbor Island Road. The shoreline consists mainly of bulkheads. The State, through the adoption of Chapter 715, Statues of 1984, found that tidelands surrounding Harbor Island are generally inaccessible to the public and not suitable for public trust uses (see Section 2.5.2). Harbor Island CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -18 Linda Isle. Created in 1933 and developed in the 1960s, Linda Isle is a 107 -lot single - family community on a private island southwest of the Coast Highway Bridge. A gated bridge connects Linda Isle to the mainland at Bayside Drive. The shoreline consists of bulkheads and a small sandy beach. All of these communities are long established. New development is generally of a type and scale that does not have a direct adverse impact on existing public access. Such new development generally consists of additions or demolition and subsequent reconstruction of existing structures. Requiring public access under such circumstances would not present a reasonable relationship between the exaction and a project and would be disproportionate to the impact. However, new development resulting in significant increases in land use density or intensity would have the potential to have a direct adverse impact on public access. Similarly, new development that limits or eliminates private recreational facilities within such communities could place additional demand on public recreational facilities, including beaches. Under such circumstances, public access mitigation in a manner consistent with the public access policies of the Coastal Land Use Plan would be required. Policies: 3.1.5 -1. Prohibit new development that incorporate gates, guardhouses, barriers or other structures designed to regulate or restrict access where they would inhibit public access to and along the shoreline and to beaches, coastal parks, trails, or coastal bluffs when there is substantial evidence that prescriptive rights exist. 3.1.5 -2. Prohibit new private streets, or the conversion of public streets to private streets, where such a conversion would inhibit public access to and along the shoreline and to beaches, coastal parks, trails, or coastal bluffs when there is substantial evidence that prescriptive rights exist. 3.1.5 -3. Require public access consistent with public access policies for any new development in private /gated communities causing or contributing to adverse public access impacts. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -19 3.1.6 Preferential Parking Districts Newport Island In Newport Beach, there is only one preferential parking district in the coastal zone. It was established for Newport Island in 1981 due to impacts associated with vehicle parking on streets and alleys by nonresidents for extended periods of time. The establishment of the Newport Island preferential parking district was determined not to adversely impact coastal access and recreation due to the island's isolated location, lack of beaches and swimming areas, and narrow streets. The establishment of additional preferential parking districts may be necessary where no other practical or feasible alternative exists to protect the public health, safety, and general welfare. Under such circumstances, if there is a direct impact to coastal access or recreation, preferential permit parking fees could be established to fund mitigation programs. Policies: 3.1.6 -1. Prohibit the establishment of new preferential parking districts in the coastal zone except in areas where such restrictions would not have a direct impact to coastal access, including the ability to use public parking, or where no other practical or feasible alternative exists to protect the public health, safety or general welfare. 3.1.6 -2. Require a coastal development permit to establish new, or modify existing, preferential parking districts. 3.1.6 -3. Use preferential parking permit fees to fund programs to mitigate impacts to coastal access. 3.1.6 -4. Where appropriate, establish a graduated preferential parking permit fee schedule where progressively higher fees are required for each permit for households with multiple permits. 3.1.6 -5. Limit the number of preferential parking permits issued per household. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -20 3.1.7 Temporary Events 2e Street Beach Newport Beach's coastal areas have long been the venue for temporary events, including film production, surfing contests, volleyball tournaments, runs, races, concerts, boat shows, and other such competitions, exhibitions, and events. Also, a number of view parks have become popular locations for large private gatherings. The nature and frequency of such events has raised concerns relating to their impact to coastal resources, public access, and on adjacent residential areas, during these events. Newport Beach regulates temporary events by requiring special event permits. It is City policy that athletic contests using City streets are not permitted during the summer (June 15 - September 15). Surfing contests are not permitted during the - Memorial Day weekend or during the summer. There are also limits on the number of such events that can be conducted each year and a minimum number of weeks • between each surfing contest. However, exceptions can be granted. - Inspiration Point and Lookout Point have become popular locations for weddings and other events. Peninsula Park is also a popular location for weddings, as well as company picnics and other private gatherings. Excessive reservations for the use of these parks has seriously limited public access. Furthermore, the use of these parks by caterers, party rental companies, professional party, event, or wedding planners - for private parties presented the appearance of commercialization of public parks. This prompted the establishment of a policy placing restrictions on reservations from the Memorial Day weekend to the Labor Day weekend. The number of attendees or participants at any one time is also restricted. Policies: 3.1.7 -1. Continue to require special event permits for temporary events and continue to require applications to provide details on event characteristics, including duration (including set up /assembly and break down /dismantle start and completion times), event hours, per day estimated attendance, parking arrangements, traffic control, noise control, waste removal, insurance, equipment to be used, food CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -21 service, entertainment, sponsorships, and advertising and marketing plans. 3.1.7 -2. Condition special event permits for temporary uses in the coastal zone to minimize impacts to public access, recreation and coastal resources. 3.1.7 -3. Continue to limit the number and frequency of temporary events in the coastal zone held from the Memorial Day weekend to Labor Day. 3.1.7 -4. Require a coastal development permit for temporary events held in the coastal zone that meet all of the following criteria: 1. Held between the Memorial Day weekend and Labor Day; 2. Occupy any portion of a public sandy beach area; and 3. Involve a charge for general public admission where no fee is currently charged for use of the same area. A coastal development permit shall also be required for temporary events that do not meet all of these criteria, but have the potential to result in significant adverse impacts to public access, recreation and /or coastal resources. Peninsula Park CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -22 3.1.8 Temporary Closures For many years, large crowds have been drawn to the streets of West Newport during the Independence Day holiday. The party atmosphere that pervades the area attracts these crowds. Large parties are held at many of the rental homes in the area, which often extend into the front yards and balconies, and even onto rooftops. The large crowds, the consumption of alcohol and the interaction between partygoers and Independence Day crowds in West Newport the crowds In the streets has resulted in an average of over 170 arrests and over 1,350 citations each year. The potential for a serious outbreak of violence exists throughout the daylight hours and increases dramatically in the evening. This environment dissuades visitors and residents from enjoying the beach or bay during Independence Day. The City has tried to reduce illegal drinking and minimize the potential for violence by significantly increasing the number of police and temporarily closing certain streets to pedestrians and visitors. The street closures do not restrict access to the beach but do function to fragment the crowds and reduce the number of people parading along Seashore Drive - an area where most arrests are made. The street closures are temporary - typically lasting less than twenty -four hours. Policies: 3.1.8 -1. Pursuant to the Section 21101 of the Vehicle Code, the City may adopt rules and regulations regarding the temporary closing of portions of any street for celebrations, parades, local special events, and other purposes when necessary for public safety. 3.1.8 -2. The City may temporarily close certain streets in West Newport for a period of no more than twenty -four hours during the Independence Day holiday when, in the opinion of the Police Chief or his designee, the closure is necessary to protect the public safety. In no event shall any street closure prevent or interfere with the public's access to the beach or bay. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -23 3.2 Recreation and Support Facilities Coastal Act policies related to recreation and support facilities that are relevant to Newport Beach include the following: 30212.5. Wherever appropnate and feasible, public facilities, inducting parking areas or facWes, shall be distributed tMaughout an area so as to magate against the impacts, social and otherwise, of overcrowding or overuse by the public of any single area. 30213. Lower cast vision and recreational facilities shell be proetcted, arooraged, and, where feasible, provided. Developments providing public recreational opportunities are Vdaned 30220. Coastal areas suited for water - oriented recreational actvibes that cannot readily be provided at inland water areas shall be protected for such uses 30221. Oceanhom land suitable for recreational use shall be protected for recreational use and development unless present and foreseeable future demand for public or commercial recreational activities dig could be accommodated on the property is already adequately provided for in the area. 30222. The use of pinnate lands %nibble for visitor - serving commercial recreational facilities designed to enhance public opportunities for coastal recreation shall have pdcrity over private residential, general industrial, or general commercial development, but not wen agriculture or coastal-dependent industry. 30223. Upland areas necessary to support coastal recreational uses shall be reserved for such uses, where feasible 30252 The location and amour of new development should maintain and enhance public access to the coast by (1) fackit" the provision or extension of transit service, (2) providing commercial facilities within or adjoining residential davehopment or in other areas duct will martyrize the use of coastal access roads, (3) providing nonautomoMYe circulation within the development, (4) providing adequate parking facilities or providing substitute meal of serving the development with public transportation, (5) assuring the potential for public transit for high intensity uses such as high-rise office buildings, and by (6) assuring that the recreational needs of new resderts will not overload nearby coastal recreation areas by correlating the amount of development with local park acquisition and development plans with the provision of orske recreational facilities to serve the new development. 3.2.1 Recreational Opportunities Throughout its history, Newport Beach has been a major recreational center. There are over 8 miles of sandy beaches that provide opportunities for sunbathing, volleyball, swimming, suiting, windsurfing and other recreational activities. Beach attendance averages 9.4 million people annually. Newport Bay and Harbor are used for a wide variety of recreational activities, including boating, diving, excursions, fishing, kayaking, paddle boarding, parasailing, rowing, sailing, swimming, and windsurfing. The City provides approximately 180 acres of public parks in the coastal zone (see Coastal Access and Recreation Map). These parks provide areas and facilities for a variety of recreational activities. The City also provides two recreational piers. The 800 - foot Newport Pier is located at the end of Newport Boulevard (McFadden Place) in McFadden Square. Beach near Balboa Pier CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -24 The 950 -foot Balboa Pier is located at the end of Main Street in Balboa Village. The City also provides ten public docks in the harbor, which can be used for boat launching and fishing. The City and County also co -own the Newport Aquatic Center. Located on Northstar Beach, the Newport Aquatic Center provides an opportunity for the public and members to kayak and canoe in Upper Newport Bay as well as advanced training facilities for world -class athletes. The County and the State also operate recreational areas in Newport Beach. The County's 100 -acre Newport Dunes Aquatic Park provides opportunities for camping, boating, canoeing, kayaking, swimming and other water and beach activities. The 752 -acre Upper Newport Bay Marine Park and 140 -acre Upper Newport Bay Nature Preserve provide opportunities for canoeing, kayaking, horseback riding, biking, and hiking. The Fun Zone in Balboa Village Policies: Commercial areas adjacent to beaches and the bay play an important role in providing and enhancing recreational activities in the coastal zone. A large number of businesses provide recreational services to residents and visitors of the coastal zone. These include charter, entertainment and excursion vessels, sports equipment rentals, launching facilities, amusement facilities, and shops and restaurants. 3.2.1 -1. Protect, and where feasible, expand and enhance recreational opportunities in the coastal zone. 3.2.1 -2. Continue to provide opportunities for a wide range of recreational activities at City parks and beaches. 3.2.1 -3. Continue to cooperate with the State Department of Parks and Recreation, the State Department of Fish and Game, and Orange County to protect, expand and enhance opportunities for recreational activities at County and State beaches and parks. 3.2.1 -4. Continue to allow recreational commercial uses in commercial areas adjacent to beaches and the bay. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -25 3.2.2 Support Facilities and Services Newport Beach provides abundant coastal access and recreational opportunities. However, it is equally important to provide adequate support facilities and services to enable the public to fully avail themselves of these opportunities. Support facilities include parking, restrooms and showers. Support services include lifeguard services and instruction and education programs. It is also important that such facilities and services be well distributed throughout the area to avoid overcrowding or overuse by the public (see Support Facilities Map). The lack of informational signage to direct the public to support facilities can impede public access. Many of Newport Beach's smaller beaches are difficult to find and access to some coastal areas is not easily apparent due to intervening topography or development. Furthermore, coastal visitors seeking support facilities can impact residents and coastal resources. For example, coastal visitors searching for parking areas contribute to traffic congestion and noise. Visitors sometimes damage habitats and bluffs to reach coastal areas when paths or trails are not clearly identified. A comprehensive coastal access signing program will reduce these impacts and ease conflicts between property owners and coastal visitors. Parking West Newport. West Newport has over a mile and a half of wide sandy public beaches. Public parking is provided primarily by 240 spaces at West Newport Park and by on -street parking in the residential neighborhoods, including an average of two on -street parking spaces at beach street -ends between 3e Street and Summit Street. Balboa Peninsula. The Balboa Peninsula has over three miles of wide public beaches and several smaller bay Parking lot in West Newport Park beaches.

Restroom and /or shower facilities are also provided at the County's Upper Newport Bay Nature Preserve, and at the Newport Dunes Aquatic Park. Services and Proarams Newport Beach is regarded as having one of the finest lifeguard services in the world. In 2003, Newport Beach provides 16 fulltime lifeguards and 180 seasonal lifeguards operating out of up to 40 lifeguard towers. The lifeguard fleet consists of 13 trucks and 3 rescue boats. Newport Beach lifeguards average 4,100 rescues, 83,000 preventative actions, 3,400 medical aid calls, and 570 lost person calls each year. The Junior Lifeguard Program continues to be the most popular program during the summer months, drawing about 1,200 participants each year. It has provided invaluable training in water safety practices and rescue techniques to over 20,000 youths since its inception in 1983, and is a prime source for identifying future lifeguards. Newport Beach offers "beach camps" for children in the summer months, allowing children from all communities to enjoy a week at the beach. Also countless day .junior Lifeguard training camps visit the beaches for their field trips. Newport Beach also provides instruction in a number of coastal recreation activities, including volleyball, suiting, and sailing. In 2003, Newport Beach has a fleet of 14 Sabots and 3 Lidos, which are used to teach over 200 children a year to sail. Newport Beach also conducts volleyball and CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -28 suiting tournaments. Educational and Interpretative Facilities The City, County, and private organizations provide several coastal- related educational and interpretative facilities and programs. Located in the Upper Newport Bay Nature Preserve, the Muth Interpretative Center is a 10,000 square foot educational facility, which provides exhibits and programs on the ecology of the Upper Newport Bay. The Back Bay Science Center planned for Shellmaker Island will include exhibits for water quality education and research programs and ecological interpretive stations. Located on a replica of a Delta paddlewheeler, the Newport Harbor Nautical Museum Marine provides exhibits and programs on the nautical heritage of Newport Harbor, Southern California and the Pacific Region. Tide pod exwsion at We Corona The Little Corona tide pools in the Newport Beach Marine Conservation Area receives thousands of visitors each year. The Little Corona tide pools are managed by the Newport Beach's Tidepool Ranger program. Tidepool Rangers are trained volunteers who educate and interact with visitors to the tide pools. Tidepool Rangers inform visitors of the rules and regulations of the Marine Conservation Area and protect tide pool resources. The great number and variety of support facilities and services reflects Newport Beach's commitment to protecting and enhancing public coastal access and recreational opportunities. However, changes in demographics and recreational interests have and will continue to alter the public's demand for support facilities and services. Therefore, it is important that Newport Beach continue to have the ability to respond to these changes while continuing to provide comparable facilities and levels of service. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -29 Policies: 3.2.2 -1.

Newport Pier Park CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -30 3.2.3 Access for Persons with Disabilities People with disabilities that limit their mobility require special improvements in order to be afforded access to coastal resources. Newport Beach is working to ensure that persons with disabilities have access to coastal areas through the retrofitting of existing public facilities or the construction of new facilities. West Newport/Balboa Peninsula. With relatively level terrain, West Newport and the Balboa Peninsula provide a good point of coastal access for people with disabilities. Parking spaces for the disabled are provided at West Newport Park, the Newport Pier, and the Balboa Pier. Accessible restrooms are also provided at these locations. The Oceanfront Boardwalk provides a smooth level pathway along the beach for almost the entire length of the peninsula. Newport Pier and Balboa Pier are also accessible and have smooth concrete decks. Hard surface pathways are provided at 1 Vh Street, 12"' Street, Orange Street, and Island Avenue. These pathways extend oceanward to allow a view of the surfline by persons in wheelchairs. Sidewalks along the perimeter of parking lots at Newport Pier and Balboa Pier and at the Newport Elementary School playground also provide access near the surfline. Newport Beach also provides beach wheelchairs at the lifeguard headquarters at Newport Pier. Island Avenue disabled access Upper Newport Bay.

CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -32 3.3 Vessel Launching, Berthing, and Storage Coastal Act policies related to vessel launching, berthing and storage that are relevant to Newport Beach include the following: 30224. Increased recreational boating use of coastal waters shall be encouraged. in accordance with this division. by developing dry storage areas. increasing public launching facilities. providing additional berthing space in existing harbors. limiting non-water-dependent land uses that congest access corridors and preclude boating support facilities. providing harbors of refuge. and by providing for new boating facilities in natural harbors. new protected water areas, and in areas dredged from dry land. 30234. Facilities serving the commercial fishing and recreational boating industries shall be protected and, where feasible. upgraded. Existing commercial fishing and recreational boating harbor space shall not be reduced unless the demand for those facilities no longer exists or adequate substitute space has been provided. Proposed recreational boating facilities shall. where feasible, be designed and located in such a fashion as not to interfere with the needs of the commercial fishing industry. 30234.5. The economic, commercial. and recreational importance of fishing activities shag be recognized and protected. Newport Harbor is the largest small craft harbor in the United States with over 9,000 boats at 2,119 commercial slips and side ties, 1,221 bay moorings, and 1,230 piers. Newport Beach recognizes the importance of protecting and enhancing services and facilities that are essential to a working harbor. 3.3.1 Vessel Launching Vessel launching refers to areas or facilities where vessels may be placed into and retrieved from the water. This could be as simple as hand - carried boat launching at a beach, or involve structures, such as ramps and docks, or equipment such as cranes, lifts, and hoists. Newport Harbor provides a variety of locations and facilities for vessel launching. A public trailer launching facility with 7 lanes is located at the Newport Say/Harbor The terms 'Newport Bay and 'Newport Harbor" are often used interchangeably. Newport Bay is an as" consisting of the lower Newport Bay (south of Pacific Coast Highway) and the Upper Newport Bay #Wth of Pacific Coast Highway). Newport Harbor generally refers to all the water area within lower Newport Bay and witivn the Upper Newport Bay, exclusive of the Upper Newport Bay Marine Park Newport Dunes Aquatic Park. Hand carried boat launching is permitted at Newport Aquatic Center at North Star Beach, the Orange County Harbor Patrol facility, and at 21 street end beaches on the Balboa Peninsula and 22 street end beaches on Balboa Island. Vessel launching facilities are provided at the Orange Coast College David A. Grant Collegiate Rowing Center and the Boy Scout Sea Base in association with their programs. Private vessel launching sites are also provided at commercial marinas and boat yards. Yacht clubs and boating associations also provide vessel launch sites for their members. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -33 Policies: 3.3.1 -1. Protect, and where feasible, expand and enhance vessel - launching facilities in Newport Harbor. 3.3.1 -2. Protect, and where feasible, expand and enhance low -cost public launching facilities, such as trailer launch ramps, boat hoists, commercial landing facilities, and organized recreational boating launch facilities. 3.3.2 Berthing and Storage 1 e street public dock Berthing refers to areas or facilities intended for the storage of a vessel in water. These can involve anchorage and mooring areas, marinas, or individual slips. In addition to the simple docking or mooring of vessels by their owners, berthing can also be associated with boat rentals, vessels used in the charter boat industry, brokered vessels stored for sale, yacht and sailing clubs, and vessels staged for entry into upland shipyards. Newport Beach provides over 1,200 bay moorings in the harbor. Approximately 450 are onshore moorings (moorings linked to the beach) and 750 are offshore moorings (moorings anchored into the Harbor floor). The County Harbor Department provides a guest mooring area offshore of the Harbor Patrol facility. Offshore moorings CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -34 Anchorages are water areas outside of navigation channels designated for the temporary anchorage of vessels, using their own anchoring tackle. A free public anchorage area is provided off of Lido Isle. Newport Harbor has 16 marinas providing over 2,100 slips. The 172 -slip Balboa Yacht Basin is city -owned and operated. Guest slips are provided at the Orange County Harbor Patrol facility and at several commercial marinas. Newport Beach also provides 5 public docks on the Balboa Peninsula and 5 public docks on Balboa Island for loading and unloading passengers, supplies, and boating gear and for similar purposes. A guest dock is also planned for the Rhine Wharf. A large number of vessels are berthed at piers. Most of Newport Harbor's over 1,200 piers are connected to residential properties. Commercial piers are used primarily to berth charter, entertainment, and excursion vessels and vessels for sale or rent. The Rhine Channel Policies: Dry storage of vessels is on -land storage of vessels including vessels normally stored in open or enclosed rack structures, on trailers, on cradles, on boat stands, or by other means. Commercial dry storage facilities are provided at the Newport Dunes Aquatic Park and at some boat yards. Some yacht clubs, boating associations, and community associations provide dry storage for their members. 3.3.2 -1. Protect, and where feasible, enhance and expand marinas and dry boat storage facilities. 3.3.2 -2. Continue to provide shore moorings and offshore moorings as an important source of low -cost public access to the water and harbor. 3.3.2 -3. Provide anchorages in designated areas, which minimize interference with navigation and where shore access and support facilities are available. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -35 3.3.2 -4. Continue to enforce the ordinances that require moored and docked vessels to be seaworthy and navigable and thereby preserve the positive image of the harbor and promote public use of the water. 3.3.2 -5. Protect, and where feasible, enhance and expand guest docks at public facilities, yacht clubs and at 11 Street boat launch and onshore moorings privately owned- marinas, restaurants and other appropriate locations. 3.3.2 -6. Protect, and where feasible, expand and enhance facilities and services for visiting vessels, including public mooring and docking facilities, dinghy docks, guest docks, club guest docks, pump -out stations and other features, through City, County, and private means. 3.3.3 Harbor Support Facilities Harbor support facilities are uses, equipment, and vessels that provide repair, maintenance, new construction, parts and supplies, fueling, waste removal, cleaning, and related services to vessels berthed in, or visiting the harbor. Harbor support facilities are considered essential to maintaining a working harbor. Increased environmental regulation and real estate price inflation in coastal communities have impacted Marine service station a number of harbor support businesses. Those businesses that do not have to be on the water have moved to inland locations. Those that are more water dependent have been involved in land use conflicts with residential and other land uses. Newport Beach has used land use controls as the primary method to CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 3 -36 provide for the continuation of harbor support uses and minimize land use conflicts. However, additional strategies and incentives may be necessary to protect these facilities. Policies: 3.3.3 -1. Protect, and where feasible, expand and enhance facilities necessary to support vessels berthed or moored in the harbor, such as boat haul out facilities. 3.3.3 -2. Protect, and where feasible, expand and enhance existing harbor support uses serving the needs of existing waterfront uses, recreational boaters, the boating community, and visiting vessels. 3.3.3 -3. In considering the essential nature of land uses that support the harbor, consider whether or not such support uses can be relocated to inland locations and /or if technological advances will eliminate the need such support uses in the foreseeable future. 3.3.3 -4. Support private sector uses, such as vessel assistance, that provide emergency, environmental enhancement and other services that are not provided by the public sector and that are essential to the operation of a working harbor. 3.3.3 -5. Develop strategies to preserve uses that provide essential support for the vessels berthed or moored in the Harbor. The strategies must be feasible, cost effective, and respect the property rights of waterfront owners and lessees. The strategies may include parking waivers, development transfers, density bonuses and voluntary purchase of conservation easements. 3.3.3 -6. Develop and implement a signing program to assist owners /operators of visiting vessels to locate harbor support facilities.

Marine resources shall be maintained, ertmnced, and, where feasible, restored. special protection shall be given to areas and species of special biological or economic significance. Uses of the marine environment shall be carried out in a manner that will sustain the biological productivity of coastal waters and that will maintain healthy populations of all species of marine organisms adequate for long -term commercial, recreational, scientific, and educational purposes. 30231. The biological productivity and the quality of coastal waters, streams, wetlands, estuaries, and lakes appropriate to maintain optimum populations of marine organisms and for the protection of human health shall be maintained and, where feasible, restored through, among other means, minimizing adverse effects of waste water discharges and entrainment, controlling runoff, preventing depletion of ground water supplies and substantial interference with surface waterflow, encouraging waste water reclamation, maintaining natural vegetation buffer areas that protect riparian habitats, and minimizing alteration of natural streams. 30240. (a) Environmentally sensitive habitat areas shall be protected against any significant disruption of habitat values, and only uses dependent on those resources shall be allowed within those areas. (b) Development in areas adjacent to environmentally sensitive habitat areas and parks and recreation areas shah be sited and designed to prevent impacts which would significantly degrade those areas, and shall be compatible with the continuance of time habitat and recreation areas. 4.1.1 Environmentally Sensitive Habitats Section 30107.5 of the Coastal Act defines "environmentally sensitive area' as "any area in which plant or animal life or their habitats are either rare or especially valuable because of their special nature or role in an ecosystem and which could be easily disturbed or degraded by human activities and developments." Section 30240 of the Coastal Act requires that environmentally sensitive habitat areas (ESHAs) be protected against any significant disruption of habitat values. Only uses dependent on Upper Newport Bay Marine Pak those resources are allowed within ESHAs and adjacent development must be sited and designed to prevent impacts that would significantly degrade the ESHA and must be compatible with the continuance of the ESHA. The Coastal Act criteria for determining whether an area qualifies as an ESHA are based upon ecological importance, including the rarity or function of the habitat, CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -1 and the habitat's sensitivity. Rarity relates to either the natural limited occurrence of the habitat in the region or of the diminishment of what was an extensive habitat due to cumulative losses. Function relates to the importance of the habitat to the ecosystem, such as functioning as a migration corridor for wildlife. Sensitivity relates to the habitats tolerance to disturbance or degradation. The California Department of Fish and Game (CDFG) California Natural Diversity Database ( CNDDB) identifies natural communities that are considered rare because of their highly limited distribution. These communities may or may not contain rare, threatened, or endangered species. The following CNDDB terrestrial natural communities are known to occur within the coastal zone in Newport Beach and the City's sphere of influence: • Dune habitats, including southern coastal foredunes and southern dune scrub. • Scrub habitats, including southern coastal bluff scrub, maritime succulent scrub, and Diegan coastal sage scrub. • Chaparral habitats, including southern mixed chaparral and southern maritime chaparral. • Riparian habitats, including southern willow scrub, southern coast live oak riparian forest, southern cottonwood willow riparian forest, southern arroyo willow forest, southern black willow forest, and southern sycamore alder riparian woodland. • Marsh habitats, including coastal brackish marsh, coastal freshwater marsh, and southern coastal salt marsh. ■ Southern coastal needlegrass grassland. • Southern hardpan vernal pools. • Freshwater seeps. ■ Alkali meadows. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -2 In determining whether a habitat area meets the statutory definition of ESHA contained in Section 30107.5 of the Coastal Act and should be designated as an ESHA, the following attributes need to taken into consideration: • The Identification of CDFG /CNDDB natural communities. • The recorded or potential presence of plant or animal species designated as rare, threatened, or endangered under State or Federal law. • The presence of coastal streams or wetlands. • The degree of habitat integrity /connectivity. While most of the above habitat characteristics can be documented from a variety of sources, habitat integrity /connectivity is a more subjective measure of biological value, which considers various attributes affecting a given habitat's quality in a particular geographic area. Attributes contributing to or detracting from habitat integrity include: • Patch size and connectivity. Large "pieces" of habitat adjacent to or contiguous with similar or related habitats are particularly useful for more mobile species that rely on larger territories for food and cover. • Presence of invasive /non- native species. Invasive /non- native species often provide poorer habitat for wildlife than native vegetation. Proliferation of exotic plant species alters ecosystem processes and threatens certain native species with extirpation. • Disturbance. This includes disturbance due to human activities such as access (trails), dumping, vegetation removal, development, pollution, etc. ■ Proximity to development. Habitat areas bordering development provide marginal habitat values to wildlife due to impacts from negative edge effects. This proximity presents the possibility of secondary effects to the habitat due to spillover or human intrusion. Deterioration of habitat results from intrusion of lighting, non - native invasive plant species, domestic animals, and human activity. ■ Fragmentation. The converse of "connectedness ", habitat fragmentation is the result of development of large blocs of undisturbed, contiguous habitat. The resulting breaking up of these areas into isolated, disjunct parcels can create barriers to migration, reduce wildlife food and water resources and generally compress territory size to reduce existing wildlife populations to non - viability. Fragmentation increases negative edge effects, whereby the CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -3 interior area of habitat is affected by the different conditions of the disturbance on its edges. The smaller a particular habitat is, the greater the proportion of its area which experiences the edge effect, and this can lead to dramatic changes in plant and animal communities. In general, loss of habitat produces a decline in species total population size, and fragmentation of habitat can isolate small subpopulations from each other. If, based on site - specific analysis by a qualified biologist, a habitat area is degraded beyond the point of restoration or is isolated in a manner that it no longer has habitat value or a special nature or role in the ecosystem, the habitat area does not meet the statutory definition of ESHA contained in Section 30107.5 of the Coastal Act. Therefore, such habitat areas do not warrant the special land use and development restrictions of Section 30240 of the Coastal Act. Policies: Define any area in which plant or animal life or their habitats are either rare or especially valuable because of their special nature or role in an ecosystem and which could be easily disturbed or degraded by human activities and developments as an environmentally sensitive habitat area (ESHA). Using a site - specific survey and analysis by a qualified biologist, evaluate the following attributes when determining whether a habitat area meets the definition of an ESHA: A. The Identification of CDFG /CNDDB natural communities. B. The recorded or potential presence of plant or animal species designated as rare, threatened, or endangered under State or Federal law. C. The presence of coastal streams or wetlands D. The degree of habitat integrity /connectivity. Attributes to be evaluated when determining a habitat's integrity /connectivity include the habitat's patch size and connectivity, the presence of invasive/non- native species, the level of disturbance, the proximity to development, and the level of fragmentation. Existing developed areas and fuel modification areas required by the CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -4 City of Newport Beach Fire Department or the Orange County Fire Authority for existing, legal structures do not meet the definition of ESHA. 4.1.1 -2. Require a site - specific survey and analysis prepared by a qualified biologist as a filing requirement for coastal development permit applications where development would occur within or adjacent to areas identified as a potential ESHA. 4.1.1 -3. Design and site new development, including landscaping, to protect ESHAs against any significant disruption of habitat values. 4.1.1 -4. Design land divisions, including lot line adjustments, to preclude new development within and minimize impacts to ESHAs. 4.1.1 -5. Limit uses within ESHAs to only those uses that are dependent on such resources, except where application of such a limitation would result in a taking of private property. If the application of ESHA policies would likely constitute a taking of private property, then a non - resource dependent use shall be allowed on the property, provided development is limited to the minimum amount necessary to avoid a taking and the development is consistent with all other applicable resource protection policies. 4.1.1 -6. Public access improvements and educational, interpretative and research facilities are considered resource dependent uses. 4.1.1 -7. Where feasible, confine development adjacent to ESHAs to low impact land uses, such as open space and passive recreation. 4.1.1 -8. Maintain a buffer of sufficient size to ensure the protection of ESHAs. 4.1.1 -9. Require the use of native vegetation and prohibit invasive plant species within ESHAs and ESHA buffer areas. 4.1.1 -10. Shield and direct exterior lighting away from ESHAs to minimize impacts to wildlife. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -5 4.1.2 Marine Resources Marine Habitats Newport Beach and surrounding ocean waters have very diverse marine habitats. These include the marshes and wetlands in Upper Newport Bay, the developed channels, beaches, and hard structures (bulkheads, seawalls, docks, pilings, and jetties) of Lower Newport Bay, and the intertidal and subtidal landforms (sandy beaches, rocky intertidal, sandy subtidal, and subtidal reefs) along the coast of Newport Beach Marine ConservaUOn Area Newport Beach. Section 30230 of the Coastal Act requires that marine resources be maintained, enhanced, and, where feasible, restored. Protection of marine habitats is required not only for their biological significance, but also for their commercial, recreational, scientific, and educational value. Open estuary and salt marsh habitats occur in the Upper Newport Bay and the Semeniuk Slough. The Upper Newport Bay is one of the largest coastal wetlands remaining in southern California and is an ecological resource of national significance. The Semeniuk Slough is a relatively large, uninterrupted open estuary/coastal salt marsh that provide wildlife with a relatively large, diverse area for foraging, shelter, and movement. The habitats of the Semeniuk Slough and the Upper Newport Bay are discussed further in Section 4.1.3 (Environmental Study Areas). Eelgrass (Zostera marina) is a marine plant that grows in Newport Harbor at depths below the low tide line and into the navigational channels. This true marine grass forms meadows and attracts many invertebrates and fishes that use the vegetation as foraging and nursery habitat. Eelgrass is discussed in more detail in Section 4.1.4 (Eelgrass Meadows) and Section 4.2.5 (Eelgrass Protection and Restoration). The Newport Beach Marine Conservation Area is located along the Corona del Mar shoreline and extends 200 feet offshore. Numerous types of invertebrates, algae, seagrass, fishes, and seabirds occur within the limits of the refuge, and marine mammals occasionally pass through. The Newport Beach Marine Conservation Area is discussed further in Section 4.1.3 (Environmental Study Area 11). CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -6 The Newport Submarine Canyon is a unique coastal feature that begins immediately seaward of the Newport Pier at a depth of 8 meters (25 feet). Bottom depths rapidly increase to nearly 30 meters (100 feet) within 400 meters (1,200 feet) from shore and 100 meters (300 feet) deep within 1,300 meters (3,900 feet) from shore. This geological feature is believed to have been formed by the ancestral Santa Ana River, and it is the exit pathway Rwresemaaon of the Newpot submarine Canyon for southward - moving sands transported through littoral drift currents at the end of the San Pedro Littoral Cell. In an effort to reduce the sand loss, the U.S. Army Corps of Engineers constructed six groins along West Newport to hold the sand. The groins have been partially successful. Biologically, the submarine canyon is unique because it acts as a pathway for cold, nutrient -rich waters that upwell from deeper offshore waters to the shallower nearshore shelf. Additionally, the canyon acts as a pathway through which deeper water species of fish, squid, shark, and jellyfish, sometimes can be found close to shore. The canyon is also an important fishing zone for the Dory Fishing Fleet. Sensitive Marine Species Several species of marine mammals frequent the nearshore waters along the Newport Beach coastline. All marine mammals are protected by the Marine Mammal Protection Act. Several whales are federally listed endangered species. The marine mammals that have the greatest potential to occur locally are California sea lion (Zalophus californicus), harbor seal (Phoca vitulina), California gray whale (Eschrichthius robustus), killer whale (Orcinus orca), common dolphin (Delphinus delphis), bottlenose dolphin (Tursiops truncates), Pacific white sided dolphin (Lagenorhynchus obliquidens), and Dall's porpoise (Phocenoides dalh). The most common, the California gray whale, was delisted as an endangered species in 1994 because of significant increases in its population numbers in recent years. California gray whales are common between December and April, as they migrate between their summer feeding grounds in the Bering Sea and their Baja California calving lagoons. Individuals sometimes enter the Newport Harbor Entrance Channel. Pods of bottlenose dolphin are occasionally observed swimming in the surf zone or immediately outside the surf zone along the Newport coastline. California sea lions are frequently observed within Newport Harbor, CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -7 particularly in the vicinity of the sports fishing boats near the Balboa Pavilion. Although giant kelp (Macrocystis pyrifera) beds do not have official status as a sensitive habitat or resource, kelp forests afford protection and cover for many marine invertebrates and fishes. Giant kelp currently is rare within the Newport Beach and Irvine Coast Marine Conservation Areas, although historically it has occurred along the coastline between Coronal del Mar and the Newport Coast. Diebacks of kelp have occurred periodically along the southern California Coast primarily during warm water El Nino periods. However, kelp beds along the Newport to northern Laguna coastline have failed to regenerate in recent years and the reasons for this occurrence are not clear. Increases in sediment loads along the coast due to urban runoff may be a contributing factor, along with periodic large storm events that dislodge plants, sustained warmer waters temperatures during El Nino periods, and over fishing. During 2002, there were excellent conditions for giant kelp in southern California. Mild winters and cold, nutrient -rich waters enabled many kelp beds to recover naturally and rapidly. However, Orange County saw very little natural recovery. A number of giant kelp reforestation projects are being attempted in southern California, including one in the Crystal Cove State Underwater Park. Despite the substantial declines in the distribution of giant kelp cover along the shoreline between Corona del Mar and Laguna Beach, a stand of giant kelp has maintained itself within Newport Harbor Entrance Channel, along the west jetty. The giant kelp bed is discussed further in Section 4.1.3 (Environmental Study Area 13). Kelp beds and associated reef organisms in the Newport Harbor ra55 iiOS aX S Entrance Channel Surf Ph dlPP ) is g ( Y p a sensitive marine resource that occurs in rocky shoreline and rocky subtidal habitats at depths to approximately — 20 feet MLLW. Its sensitivity is related to its use by invertebrates and fishes as nursery habitat and its susceptibility to long -term damage because it is a very slow growing species. Revegetation occurs naturally through seeding and eventually spreading of roots and rhizomes over surfaces of rocks. Surfgrass is located within the Newport Beach Marine Conservation Area, along the outer fringes of the intertidal reefs and the tops of shallow subtidal reefs. California grunion (Leuresthes tenuis) are fish that are associated with many CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -B beaches in southern California. Grunion lay their eggs in the wet beach sands during the highest spring tides between late February or early March, to as late as early September. Historically, these grunion "runs' have occurred on west- facing beaches upcoast of Newport Pier, where the beach slopes tend to be more gradual rather than south facing beaches downcoast of Newport Pier. However, there has been no recent grunion activity observed on these beaches. Grunion run activity has also occurred on Corona del Mar State Beach and Rocky Point Beach, in the Harbor Entrance mouth. Although California halibut (Paralichthys californicus) does not have a formal special species status, the California halibut is considered a sensitive species by resource agencies because of its commercial value and a continued region -wide reduction of its nursery habitat in bays and wetlands. California halibut spawn at sea and the larval stages are planktonic. After several months, the larval fish settle to the bottom, and migrate into shallow coastal waters, including Newport Bay. Halibut are distributed throughout the waters of Lower and Upper Newport Bay, primarily as juveniles, although larger individuals are caught near the ocean entrance and offshore. Young -Of- The -Year (YOTY) prefer shallow waters between about —0.45 meter (1.5 feet) and —1.0 meter (3.5 feet) Mean Lower Low Water (MLL", whereas juveniles prefer deeper channel bottoms to a maximum depth of approximately 4.5 meters (15 feet) MLLW. After spending nearly nine months in Newport Bay, juveniles will move out into the open coastal environment. Invasive Marine Species Caulerpa taxifolia is an extremely harmful, invasive species that has recently been introduced into southern California waters. It has been located within Huntington Harbour and in the Agua Hedionda Lagoon in northern San Diego County. This species has a characteristic bright green color, flat, leafy fern -like fronds (branches), and below - ground root system. Caulerpa algae can be extremely harmful to marine ecosystems because it invades and out - competes native habitats by forming a dense blanket of growth on mud, sand, or rock surfaces. It can grow in shallow coastal lagoons as well as in deeper ocean waters, and can grow rapidly and up to 9 feet in length. However, its usual form observed so far is much smaller in length. The ecological consequences of the spread of this invasive algae can be extremely serious and can result in a significant loss of plant and animal productivity. Therefore, the spread of this species is being closely monitored and areas that have become infested are being treated chemically to eradicate any growth. The management, control, and eradication of this species is the responsibility of the Southern California Caulerpa Action Team (SCCAT). Newport Bay is not currently known to be infested by this species, however, continued surveillance for undetected or new infestations is a high priority to the CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -9 SCCAT. Project site surveys for the presence of Caulerpa taxifolia are required by NOAA and CDFG prior to bottom - disturbing projects such as dredging, dock replacement, bulkhead repair. Assembly Bill 1334 (Chapter 338, Statutes of 2001) prohibits the sale, possession, and transport of Caulerpa taxifolia throughout California. The Bill also bans species of Caulerpa that look similar to C. taxifolia and are believed to have the capability to become invasive. The importation of the Mediterranean strain of Caulerpa taxifolia into the United States and interstate trade, including via the Internet, is also a federal offense under the Federal Noxious Weed Act of 1999 and the Plant Protection Act of 2000. Water Quality Runoff from the surrounding watershed threatens the biological diversity and functionality of Newport Bay and the surrounding coastal waters. This runoff includes various pollutants, such as fecal material from pets, oil and grease, fertilizers, and other urban -based pollutants. In addition, increased sediment loads decrease the extent of tidal inundation, diminish water quality, degrade habitat for endangered species, migratory water birds, and marine and estuarine fishes, and contribute to the decline of kelp forests. Water quality and sedimentation issues are discussed further in Section 4.2 (Wetlands and Deepwater Areas) and Section 4.3 (Water Quality). Policies: 4.1.2 -1. Maintain, enhance, and, where feasible, restore marine resources. 4.1.2 -2. Provide special protection to marine resource areas and species of special biological or economic significance. 4.1.2 -3. Require that uses of the marine environment be carried out in a manner that will sustain the biological productivity of coastal waters and that will maintain healthy populations of all species of marine organisms adequate for long -term commercial, recreational, scientific, and educational purposes. 4.1.2 -4. Continue to cooperate with the state and federal resource protection agencies and private organizations to protect marine resources. 4.1.2 -5. Continue to require Caulerpa protocol surveys as a condition of City approval of projects in the Newport Bay and immediately notify the SCCAT when found. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -10 4.1.3 Environmental Study Areas Newport Beach has several relatively large, undeveloped areas that contain natural habitats and may be capable of supporting sensitive biological resources. These areas are designated as environmental study areas to define them geographically, provide an overview of known and potential biological resources, identify potential threats to those resources, and propose potential mitigation measures. The following areas are designated as environmental study areas: 1. Semeniuk Slough (Santa Ana River Marsh) 2. North Star Beach 3. West Bay 4. Upper Newport Bay Marine Park and DeAnza /Bayside Marsh Peninsula 5. San Diego Creek 6. Eastbluff Remnant 7. Mouth of Big Canyon 8. Newponer North 9. Buck Gully 10. Morning Canyon 11. Newport Beach Marine Conservation Area 12. Castaways 13. Kelp Beds in Newport Harbor Entrance Channel Most of these study areas are protected as parks, conservation areas, nature preserves, and other open space areas. Nevertheless, the natural habitats in each of these study areas are subjected to various potential impacts from the surrounding urban environment. Potential adverse impacts and mitigation measures to reduce those impacts identified in the narratives below and summarized in Table 4.1 -1 (Environmental Study Area Environmental Impacts and Mitigation Measures). Eelgrass meadows within Newport Bay and coastal foredunes on the Balboa Peninsula are not included in the list of environmental study areas since their locations shift due to fluctuations in growing conditions. Eelgrass meadows and coastal foredune habitats are discussed in Section 4.1.4 and Section 4.1.5, respectively. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -11 Study Area No. 1: Semeniuk Slough Semeniuk Slough is a remnant channel of the Santa Ana River from the time when the river emptied into Newport Bay; it forms a loop around the Newport Shores residential area in West Newport. The 103 -acre Semeniuk Slough Environmental Study Area (ESA) includes the main slough channel immediately north of Newport Shores and the coastal salt marsh habitat to the north, including a narrow sliver of salt marsh habitat in the far north of the ESA, flanked by the Santa Ana River on the west and Banning Ranch on the east. Several smaller interconnected channels and inundated depressions are located throughout the salt marsh habitat. Semeniuk Slough is exposed to limited tidal influence through a tidal culvert connected between the Santa Ana River and the slough. The site contains a healthy stand of sensitive coastal salt water marshhabitat . The state endangered Belding's savannah sparrow (Passerculus sandwichensis beldingi) breeds in nearby wetland habitats including Upper Newport Bay and salt marsh in Huntington Beach but not in Semeniuk Slough. However, small Semeniuk Slough numbers of Belding's savannah sparrows forage in Semeniuk Slough, especially during the winter when breeding birds disperse. A Belding's savannah sparrow was observed within the Semeniuk Slough site on July 10, 2002. The state and federal endangered California least tern (Sterna albifrons brown), which has a large nesting colony on the Huntington Beach side of the Santa Ana River mouth, forages occasionally in the slough channels. Western snowy plovers (federal threatened) are observed occasionally in Semeniuk Slough. The California brackish water snail (Tryonia imitator), a Federal Species of Concern, has been collected in substantial numbers in the channels of Semeniuk Slough. The Semeniuk Slough ESA is characterized by open estuarine, southern coastal salt marsh, and ornamental plant communities. The S- curved channel, also referred to as Oxbow Loop, is bordered to the north by southern coastal salt marsh vegetation, which is dominated by pickleweed (Salicomia sp.) and salt grass. Most of the natural areas occur to the west of the parcel. Sea fig has invaded some of the upland portions of the parcel. Other ornamental plant species are found along the margin of the Slough, primarily in the eastern portions of the parcel and include myoporum ( Myoporum sp.), acacia (Acacia sp.), Mexican fan palm, pine (Pinus sp.), and eucalyptus. Many houses in the Newport Shores development bordering the slough have small CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -12 docks and patios that encroach into the slough. The proximity to the Newport Shores residential development has introduced numerous ornamental and non- native species to the eastern perimeter of the site, and also allows use of the slough for recreational use. A few oil -well related structures are located in the southern part of the ESA, immediately north of the main slough channel. The land surrounding these structures has been cleared. Two roads bisect the study area - one leading from the Santa Ana River levee to the Banning Ranch area, and the other leading to the oil well structures. Potential impacts to this area include water quality degradation, human activity, encroachment, invasive species, and uncontrolled public access. Studv Area No. 2: North Star Beach Located at White Cliffs Drive and North Star Lane, North Star Beach is bordered by the main channel of Upper Newport Bay to the east, Galaxy Drive to the north, and residential development to the south and west of the site. The 11.6 -acre North Star Beach ESA supports a small riparian area composed of southern willow scrub. r- Southern will d d ow scrub Is cons ere a sensitive habitat, and is listed as rare Southern coastal duff scrub habitat (in the background) at Nash or threatened or is otherwise Star Beach protected by the United States Fish and Wildlife Service (USFWS), CDFG, or local agencies. Southern willow scrub is utilized by many species of vertebrates, including birds, amphibians, and mammals. Sensitive species, such as the least Bell's vireo and southwestern willow flycatcher, have the potential to occur within this site. The beach parcel located south of the Newport Aquatics Center (NAC) consists of dredged sand material and supports predominately ruderal plant species including cheeseweed (Malva pariflora), red - stemmed fflaree (Erodium cicutarium), sea rocket, and black mustard (Brassica nigra). The bluff located to the west of the beach and the NAC facilities, and east of the adjacent residential area supports several non - native ornamental trees and shrubs including acacia, myoporum, and pine. Several saltbush shrubs are located throughout the sandy beach and bluff areas within this parcel. A small wetland supported by nuisance water runoff (from the western bluffs and residential area) is located just north of the NAC facilities. This area mainly supports willow (Salix spp.), palm (Phoenix sp.), and sedge. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -13 North of where the wetland reaches the bay, native saltwater marsh and southern coastal bluff scrub habitat is found that lacks the exotic species present in the southern portion of the study area. Potential impacts to the natural habitats in this study area include erosion, increased human activity, ambient noise, invasive species, and uncontrolled public access. Study Area No. 3: West Bay The 84.4 -acre West Bay ESA is located along Irvine Avenue from University Drive south along the east side of Galaxy Drive. It is bordered by the Upper Newport Bay Marine Park to the east, residential development to the north and west, and the North Star Beach ESA to the south. This parcel consists of four characteristic plant communities, including Diegan coastal sage scrub, at Upper Newport and Dieganeoastal sage sauD habitat southern coastal bluff scrub, disturbed a[ Upper Newport Bay Naare Preserve southern willow scrub, and non - native grassland. Much of the non - native grassland was most likely remnant coastal sage scrub habitat prior to being cleared. The Dieagan coastal sage scrub habitat is located primarily near the bay, with a few stands that border Irvine Avenue, and is primarily composed of California sagebrush, coyote brush, prickly pear (Opuntia sp.), coast goldenbush (Isocoma menziesii var. menziesit), and lemonadeberry. The southern section of the study area overlooking the bay supports southern coastal bluff scrub vegetation. Plant species associated with this area include saltbush, tree lupine (Lupines arborous), prickly pear, coyote brush, California buckwheat, coastal goldenbush, and California bush sunflower. This area is contiguous with the bluff habitat along North Star Beach. A small drainage located near 23rd Street (the remnant of Indian Springs) transports nuisance water runoff from the residential area located west of Irvine Avenue, and crosses the southern portion of the West Bay ESA before reaching the bay. This drainage supports a disturbed southern willow scrub plant community dominated by willow, eucalyptus, and giant reed. Several coastal sage scrub restoration areas, revegetated with young native shrubs, are located along CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -14 the gradual slopes located north of the drainage. Black mustard and wild oats dominate the non - native grassland plant community, which is found throughout the parcel and most often bordering Irvine Avenue. This site is used as open space as well as for recreational opportunities and includes the Muth Interpretive Center operated by the County of Orange. A paved bike and pedestrian trail is located along the crest of the West Bay parcel. Several dirt trails transect the north end of the parcel. Potential impacts to the natural habitats in this study area include erosion, increased human activity, ambient noise, invasive species, and uncontrolled public access. Studv Area No. 4: Upper Newport Bay Marine Park/DeAnza Bayside Marsh Peninsula The Upper Newport Bay Marine Park is located within the upper two- thirds of Upper Newport Bay. The site is bordered by Irvine Boulevard and residential areas to north and west, the lower reach of Upper Newport Bay to the south, and San Diego Creek to the east. The 787.6 -acre Upper Newport Bay Marine Park extends from Shellmaker Island to the Jamboree Road Bridge. The DeAnza Bayside Marsh Peninsula is located outside of the Reserve boundaries at the southern -most section of Upper Newport Bay, immediately north of the Coast Highway Bridge quality salt marsh, intertidal mudflats, and subtidal habitats, (Zostera marina). Southem coastal salt marsh habitat at Upper Newport Bay It consists of high including eelgrass Upper Newport Bay, one of the largest coastal wetlands remaining in southern California, is an ecological resource of national significance. Sensitive natural habitats within Upper Newport Bay include estuarine marine open water, coastal freshwater marsh, intertidal mudflat, salt panne, Diegan coastal sage scrub, and southern coastal salt marsh. Salt marsh habitat within Upper Newport Bay includes cordgrass- dominated low salt marsh, pickleweed- dominated mid salt marsh, and high salt marsh. This ESA supports several listed bird species and an endangered plant. The resident population of the state and federal endangered light- footed clapper rail CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -15 (Rallus longirostris levipes) in Upper Newport Bay represents about 65 percent of the California population of this species. Upper Newport Bay has consistently supported the highest numbers of rails of any southern California wetland, and is believed to be the only viable subpopulation remaining in the United States. The highest number of breeding clapper rails during the 1990s in Upper Newport Bay was 158 pairs in 1996. The 1999 census recorded 104 pairs. Low salt marsh dominated by cordgrass is the species' preferred nesting habitat, but it has been known to breed in brackish and even freshwater marsh. Clapper rails are found throughout the Upper Bay, heavily utilizing cordgrass marsh for nesting at several locations, including Shellmaker Island, Middle Island, Upper Island, and salt marsh habitat above the Main Dike. The state endangered Belding's savannah sparrow is a year -round resident and breeder in Upper Newport Bay. Its preferred nesting habitat is pickleweed- dominated mid salt marsh. In 1996, the population in Upper Newport bay was 252 pairs. The state and federal endangered California least tern is a seasonal resident in Upper Newport Bay from April to early September. They nest on Least De AnzalBayside Marsh Peninsda Tern Island, the smaller of two islands in the uppermost sedimentation basin. In 1999, 40 pairs of least terns nested on this island. In 2000, 60 least tern pairs nested in Upper Newport Bay and fledged 12 young. Skimmers and Forsters terns nest on the second, and larger island (Skimmer Island) in the uppermost sedimentation basin. The federally threatened coastal California gnatcatcher nests in coastal sage scrub along the margins of Upper Newport Bay. There are at least 10 pairs breeding in upland habitat surrounding Upper Newport Bay. Other listed bird species that occur in Upper Newport Bay on a seasonal basis but do not breed there include the state and federal endangered California brown pelican, the federal threatened western snowy plover, and the state endangered American peregrine falcon. The state and federal endangered plant salt marsh bird's beak occurs at several sites in high salt marsh habitat in Upper Newport Bay. It is the only listed plant species confirmed to occur in the Upper Newport Bay Marine Park. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -16 In addition to these listed species, a number of bird species that are Federal Species of Concern and /or State Species of Special Concern use the Upper Newport Bay Marine Park. The California brackish water snail, a Federal Species of Concern, is common around freshwater discharges to the Upper Bay. Because of its diversity of habitats and its location on the Pacific Flyway, Upper Newport Bay supports an impressive number and diversity of birds, particularly during fall and winter when shorebirds and waterfowl arrive from their northern breeding grounds. There are approximately 182 bird species that regularly occur in Newport Bay over a calendar year. Only about 18 percent of these are year round residents. The large number of non - resident bird species indicates Newport Bay's value not only to the local resident bird community, but also to a large number of migratory gulls, terns, raptors, shorebirds and waterfowl that are key species in ecosystems in other areas of the continent. At least 78 fish species have been identified in various studies of Upper Newport - Bay. Newport Bay is an important habitat for resident estuarine species, as well as a spawning and nursery ground for a variety of marine species including California halibut (Paralichthys californicus), yellowfiin croaker, white seabass (Atractoscion nobilis) and barred sandbass. The ecological diversity and functionality of the Upper Newport Bay Marine Park has been threatened by sedimentation from the surrounding watershed. The primary source of freshwater and sediment loads to Upper Newport Bay is San Diego Creek. Sediment from the San Diego Creek watershed has filled open water areas within the Bay. This sedimentation has decreased the extent of tidal inundation, diminished water quality, degraded habitat for endangered species, migratory water birds, and marine and estuarine fishes. Heavy sedimentation during the 1998 El Nino required dredging in 1998 and 1999. Recently, a long- term management plan was developed to control sediment deposition in the Upper Bay to preserve the health of Upper Newport Bay's habitats. That plan identified basin configurations and depths to control sedimentation in the Upper Bay. The slopes of the bluffs along Upper Newport Bay are unstable and have required stabilization devices and bluff repairs. Irrigation practices on the tops of the bluffs have contributed to both erosion and eutrophication problems in the Upper Bay. Study Area No. 5: San Diego Creek The 37.3 -acre San Diego Creek ESA is bordered by Jamboree Road to the west, Bayview Way and a commercial automobile dealership to the north, MacArthur Boulevard to the east, and the residential area adjacent to University Drive on the south. The San Diego Creek site is contiguous with the Upper Newport Bay Marine Park, and merges with the bay in the vicinity of Jamboree Road. This CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -17 study area includes two main parcels: the main channel of San Diego Creek and an adjacent saltwater marsh mitigation area located to the north. The San Diego Creek study area is dominated by southern willow scrub and southern coastal salt marsh communities. These habitats are considered sensitive, and are listed as rare or threatened or are otherwise protected by the USFWS, CDFG, or local agencies. Southern willow scrub is utilized by many species of vertebrates including birds, amphibians, and mammals. Sensitive species, such as the least Bell's vireo and southwestern willow flycatcher, Main channel of San Diego Creek have the potential to occur within this site. Southern coastal salt marsh also provides habitat for many sensitive plants and animals, which have the potential to occur within this site. The California brackish water snail, a Federal Species of Concern, is common around freshwater discharges to the Upper Bay, including San Diego Creek. The marsh site is separated from the main channel by an earthen levee, but is hydraulically recharged by San Diego Creek during high water events through an existing culvert. The marsh site consists of two primary habitat types: southern coastal salt marsh (aquatic) and southern willow scrub. The middle of the site is inundated with low -to- moderate amounts of water, and is dominated by salt marsh and emergent wetland vegetation including pickleweed, salt grass, and bulrush (Scirpus sp.). Portions of this area have been revegetated with native plants. The eastern portion of the site gives rise to southern willow scrub and primarily consists of willow (Salix sp.), mule fat, and cattails. The upland areas of this site support a mixture of habitat types and consist of shrub species, including California bush sunflower, saltbush, and mule fat. The main channel is characterized by southern willow scrub. This area is dominated by willow and mule fat, and supports a few isolated cottonwood trees (Populus sp.). Two exotic species, giant reed and brass buttons, are commonly found throughout the riparian zone. Potential impacts to the natural habitats in this study area included human activity, ambient noise, invasive species, and uncontrolled public access. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -18 Study Area No. 6: Eastbluff Remnant Southern coastal bluff scrub at Eastbluff Remnant The 36.5 -acre Eastbluff Remnant ESA extends along the eastern side of Back Bay Drive from Jamboree Road to Eastbluff Drive, and is bordered by Upper Newport Bay to the north and west, residential development to the east, and San Joaquin Hills Road to the south. This study area consists of three main plant communities, including southern coastal bluff scrub, Diegan coastal sage scrub, and southern willow scrub. Most of the study area consists of steeply sloped west - facing bluffs. The areas support mainly southern coastal bluff scrub vegetation with some evidence of Dieagan coastal sage scrub species. Plant species associated with this area include saltbush, tree lupine, coastal goldenbush, California bush sunflower, coyote brush, California buckwheat, prickly pear, cholla (Opuntia sp.), California sagebrush, and lemonadeberry. There are varying degrees of previous disturbance, mostly resulting from the adjacent residential area to the east. Several non - native species are found throughout these areas, including sea fig, tree tobacco, sweet fennel (Foeniculum vulgare), black mustard, and castor bean. The Dieagan coastal sage scrub habitat dominates the upper, less steep portions of the parcel, and is primarily composed of California sagebrush, coyote brush, prickly pear, and Mexican elderberry, poison oak, and lemonadeberry. Southern willow scrub vegetation may be found within several tributaries to Newport Bay and along the eastern edge of Back Bay Road, where water accumulates before entering the bay. These areas are dominated by willow and mule fat. Dense stands of Mexican elderberry, willow, and poison oak dominate the north - facing slopes in the northeastern portion of the East Bluff parcel. Potential impacts to the natural habitats in this study area include erosion, increased human activity, ambient noise, invasive species, and uncontrolled public access. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -19 Study Area No. 7: Mouth of Bia Canyon The 52.0 -acre Big Canyon ESA is located on the east side of Newport Bay, between Back Bay Drive and Jamboree Road. The Mouth of Big Canyon site is bordered by Upper Newport Bay to the west and residential development to the east, north, and south of the site. Many trails throughout this area provide good access for the public to observe the variety of habitats and Fresh water marsh at the mouth of Big Canyon plant communities. The backbone routes for these trails are utility access roads needed to provide access for maintenance vehicles that service the utilities that have been installed in this site. This site provides an opportunity to establish an interpretive area that allows public access to a broad range of habitats and plant community areas that should be reestablished as a destination for the public. Seven plant communities characterize this site, including southern willow scrub, Diegan coastal sage scrub, non - native grassland, southern coastal bluff scrub, southern coastal salt marsh, southern cottonwood willow riparian forest, and coastal freshwater marsh. Big Canyon is oriented perpendicular to the bay. The upper (eastern) portion of the creek supports native plants characteristic of southern willow scrub communities dominated by densely growing willows and mule fat. The upland areas within the eastern region contain a mixture of disturbed Diegan coastal sage scrub and non - native grassland. Plant species found in this area include coyote brush, lemonadeberry, black mustard, and sweet fennel. The canyon is outlined by intermittent stands of ornamental trees and shrubs including eucalyptus and acacia, which are located next to the adjacent residential zones. The mouth of the canyon widens towards the bay and supports a mixture of southern coastal bluff scrub and Diegan coastal sage scrub along both the north and south - facing slopes. These areas are dominated by California sagebrush, California buckwheat, prickly pear, saltbush, lemonadeberry, and Mexican elderberry. The western reach of the canyon creek forms a pond, while supporting a mature southern cottonwood willow riparian forest and coastal freshwater marsh. Fremont cottonwood (Popu/us fremonfii spp. fremonfit), western sycamore, and willow dominate the overstory of the riparian forest. Stinging nettle (Urtica diocia) can be CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan a -20 found amongst the herbaceous layer. The northern margins of the riparian forest show evidence of dryer climates and supports revegetated species such as holly - leaf redberry and jojoba (Simmondsia chinensis). The coastal freshwater marsh is surrounded by cattail and sedge. Remnants of the southern coastal salt marsh habitat are evident on the dredge sand deposits located immediately south of the freshwater marsh, where pickleweed is the dominant plant species. Potential impacts to the natural habitats in this study area include erosion, creek water quality runoff, sedimentation, erosion, increased human activity, ambient noise, invasive species, and uncontrolled public access. Studv Area No. 8: Newporter North The Newport North is located in bluff and mesa habitats along Back Bay Drive and San Joaquin Hills Road adjacent to Upper Newport Bay. The 49.2 -acre Newporter North ESA is bordered by Upper Newport Bay to the west, the Hyatt Newporter Hotel to the south, Jamboree Road to the east, and residential development to the east and north of the site. The Newporter North ESA is characterized by five plant Diegan coastal scrub on the slopes of Newporter North communities, including southern willow scrub (disturbed), coastal freshwater marsh, Diegan coastal sage scrub, southern coastal bluff scrub, and non - native grassland. A drainage (John Wayne Gulch) runs east to west from Jamboree Road to the bay. The upper (eastern) portion of the drainage supports native plant species that are characteristic of southern willow scrub communities including willows, mule fat, and Mexican elderberry. This drainage also supports many exotic species including myoporum, tree tobacco, eucalyptus, pampas grass (Cortaderia selloana), and sweet fennel. The lower (western) portion of the drainage widens into a coastal freshwater marsh before reaching the bay. This area is thickly vegetated and dominated by cattail, sedge, and brass buttons. Additionally, there is a wetland restoration area located in the far northeast portion of this parcel, which is dominated by willows, mule fat, and cattails. Diegan coastal sage scrub occurs at higher elevations within the parcel along the CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -21 south and north- facing slopes. Plant species associated within this area include California sagebrush, coyote brush, California bush sunflower, California buckwheat, Mexican elderberry, coastal goldenbush, and deerweed. An area located just south of San Joaquin Hills Road supports densely growing coastal sage scrub vegetation. A small square parcel of coastal sage scrub bordered by Newporter Way and Jamboree Road is found within this section of the study area. The steeper west - facing slopes, located above Back Bay Drive to the north and south of the main canyon, support southern coastal bluff scrub vegetation. Plant species associated with this area include saltbush, tree lupine, prickly pear, coyote brush, California buckwheat, coastal goldenbush, and California bush sunflower. Historically, most of the upland areas located in the southwestern portion of the parcel most likely supported coastal sage scrub communities; however land modification and clearing has disturbed these areas, leaving many sections supporting only non - native grasslands. Common species found within the non- native grassland community include black mustard, white sweetclover (Melilotus alba), artichoke thistle (Cynara cardunculus), and pampas grass. Potential impacts to the natural habitats in this study area include erosion, increased human activity, ambient noise, invasive species, and uncontrolled public access. Studv Area No. 9: Buck Gullv Buck Gully is a natural feature extending between Little Corona Beach and the San Joaquin Hills. The 74.2 -acre Buck Gully ESA does not include the sections of the canyon that are located outside of the coastal zone or within Newport Coast. The ESA is bordered by the Pacific Ocean to the southwest, and residential and commercial development to the southeast, northwest, and north of the site. Pacific Coast Highway bisects the canyon. Drainage from Buck Gully empties on to Little Corona Beach. The portion of Buck Gully between the extension of Fifth Avenue and Little Corona is under private ownership. The Buck Gully ESA is dominated by Diegan coastal sage scrub and southern mixed chaparral, with southern willow scrub, annual grassland, and coastal freshwater marsh occurring as smaller components of the community. Diegan coastal sage scrub and southern mixed chaparral encompass the majority of the gully - from the upper rims to the alluvial bottoms. A narrow ribbon of southern willow scrub riparian habitat is supported by an unnamed creek that flows along the canyon bottom the length of the gully. Patches of annual grassland occur throughout the chaparral and coastal sage scrub habitats and also in areas where native vegetation has been cleared for fire prevention. The narrow, western reach of the canyon is largely encroached upon by the adjacent residential areas to the CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -22 R1 • • • • • • Duch Gully southwest from Coast Highway southeast and northwest. The upper slopes in this area of the canyon support a mix of disturbed southern mixed chaparral, a small patch of coastal sage scrub, and non - native ornamental vegetation originating from the surrounding homes. Typical chaparral species in this area include toyon (Heteromeles arbutifolia), laurel sumac (Malosma laurina), and ceanothus ( Ceanothus sp.) Non - native and ornamental species include giant reed (Arundo donax), acacia, eucalyptus, myoporum, Mexican fan palm, Brazilian pepper tree (Schinus terebinthifolius), Peruvian pepper tree (Schinus molle), castor bean (Ricinus communis), tree tobacco (Nicotiana glauca), pampas grass (Cortaderia sp.), and fennel (Foeniculum vulgare). The canyon bottom in this area is dominated by riparian vegetation including willows (Salix spp.), blackberry (Rubus sp.), cattail (Typha sp.), and bulrush (Scirpus sp.). A small freshwater marsh comprised almost exclusively of cattail is situated at the mouth of the gully adjoining Little Corona Beach. The central section of the canyon immediately northeast of the Coast Highway, while closely confined by residential development, contains fewer ornamental plant species than the coastal portion and supports southern mixed chaparral and southern willow scrub habitats with species compositions similar to the lower canyon. The chaparral in this area supports toyon, laurel sumac, ceanothus, chamise (Adenostoma fasciculatum), lemonadeberry (Rhus integrifolia), scrub oak (Quercus berberidifolia), southern honeysuckle (Lonicera subspicata), redberry (Rhamnus crocea), bush monkey flower (Mimulus aurantiacus), and sugar bush (Rhus ovata). Approximately adjacent to the intersection of 5th Avenue and Poppy Avenue, the gully veers east and opens into a broader canyon. The southern slopes of the canyon in this area support dense stands of southern mixed chaparral, while the northern slopes support disturbed annual grassland, possibly established as chaparral and coastal sage scrub, but subsequently cleared for fire prevention by homeowners. At present, the annual grassland contains black mustard (Brassica nigra), tocalote (Centaurea melitensis), artichoke thistle (Cynara cardunculus), wild oats (Avena fatua), soft chess (Bromus hordeaceus), barley (Horedum sp.), ripgut brome (Bromus diandrus), and fennel. Diegan coastal sage scrub becomes more dominant as the canyon slopes on the upper portions of the canyon veer eastward. This community is composed of California sagebrush (Artemisia CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -23 califomica), California buckwheat (Eriogonum fasciculatum), white sage (Salvia apiana), prickly pear (Optunia sp.), coyote brush (Baccharis pilularis), blue elderberry (Sambucus mexicana), laurel sumac, lemonadeberry, and California bush sunflower (Encelia californica). The canyon floor of Buck Gully supports a southern willow scrub community, dominated by willows and mule fat (Baccharis salicifolia), with occasional western sycamore (Platanus racemosa) and cottonwood (Popu /us fremontil). Associated plant species include cattail, blue elderberry, poison oak (Toxicodendron diversilobum), rush (Juncus spp.), and nutsedge (Cyperus sp.). The upper canyon is broader than the lower canyon and is therefore less impacted by adjacent development. Vegetation in this area is primarily Diegan coastal sage scrub and southern mixed chaparral, interrupted by occasional patches of annual grassland, and southern willow scrub associated with the creek at the canyon bottom. The lower (western) portion of Buck Gully is isolated from the upper Buck Gully by the Coast Highway. This area is closely confined by residential development on the south and north. The proximity to development, accessibility by local residents and their pets, and abundance of non - native ornamental plant species detract from the quality of habitat for wildlife species in this area. The upper (eastern) portion of Buck Gully is a broad, open, relatively undisturbed canyon. Coastal sage scrub and mixed chaparral dominate much of the area, except for the riparian corridor along the canyon bottom and the tops of the canyon, which are influenced by the adjacent residential development. Much of the native vegetation near the rim of the canyon has been removed to reduce wildfire hazard. Ornamental and non - native plant species from the adjacent residential development have encroached into Buck Gully, especially in the lower, narrow portions. Annual grasslands in Buck Gully consist of nonnative annual grasses and (orbs. Some non - native inclusions were also observed in the Diegan coastal sage scrub, southern mixed chaparral, and southern willow scrub habitats. Potential impacts to the natural habitats in this study area include erosion, contaminated urban runoff, increased human activity, ambient noise, invasive species, and uncontrolled public access. Studv Area No. 10: Mornina Canyon Morning Canyon is oriented perpendicular to the coastline between Corona Highlands and Cameo Highlands. The 11.2 -acre study area is bordered by the Pacific Ocean to the west, Pelican Hills Golf Course to the east, and residential development to the north and south of the site. Morning Canyon is under private CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -24 ownership. Morning Canyon is characterized by disturbed, remnant, southern mixed chaparral vegetation on the canyon floor and along the upland slopes. This area, however, contains few remaining native species and is dominated by non - native and ornamental species that have invaded the canyon from adjacent residential areas located immediately to the northwest and southeast. Native plant species in the remnant southern mixed chaparral community include Morning Canyon near Pelican Bay GolfCoirse coyote brush, toyon, mountain mahogany (Cercopcarpus betuloides), lemonadeberry, and blue elderberry. Non- native species include fennel, pampas grass, acacia, date palm (Phoenix sp.), fig (Ficus sp.), hottentot fig (Carpobrotus edulis), Himalayan blackberry (Rubus discolor), tree tobacco, pittosporum (Piosporum sp.), and castor bean. The canyon bottom once supported a southern willow scrub and willows, mule fat, and mugwort (Artemisia douglasiana) can still be observed growing among the dominant non - native vegetation, though these species are no longer common enough to consider this habitat to be southern willow scrub. Nonnative plant species now dominate the bottom and lower slopes of the canyon and include giant reed, acacia, hottentot fig, eucalyptus, myoporum, Mexican fan palm, Brazilian pepper tree, Peruvian pepper tree, pampas grass, ivy (Hedera sp.), and fennel. Although most of the native riparian- associated species have been displaced by non - native and ornamental species, the area is still used by riparian wildlife, such as American crow (Corvus brachyrhyncus), northern mockingbird (Mimus polyglottos), mourning dove (Zenaida macroura), cedar waxwing (Bombycilla garrulous), English sparrow (Passer domesticus), raccoon (Procyon lotor), and opossum (Didelphis virginiana). The presence of a perennial watercourse along with a structurally diverse woody vegetation community provides the necessary habitat attributes that are essential to riparian- associated species. The lower, southwestern section of Morning Canyon is separated from the upper section of Morning Canyon by the Coast Highway. The entire canyon is very narrow and closely bordered by residential development on the northwest and southeast, the Pacific Ocean to the southwest, and the Pelican Hills Golf Course at the northeastern edge of the area. Ornamental species have completely CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -25 displaced native vegetation in much of canyon and now dominate throughout the majority of this ESA. Pets from the adjacent residences likely use the area and further discourage wildlife use of the canyon. Potential impacts to the natural habitats in this study area include increased human activity, ambient noise, invasive species, erosion, sedimentation, and uncontrolled public access. Study Area No. 11: Newport Beach Marine Conservation Area The 85.8 -acre Newport Beach Marine Conservation Area extends from Little Corona Beach to Cameo Shores Road. The refuge's coastline length is 0.6 miles (mi). It extends a distance of 200 feet (ft) offshore and to depths of about 1Bft Mean Lower Low Water (MLLW). This refuge is significant because it is the first section of rocky intertidal and rocky subtidal habitat south of Point Fermin, along with the Irvine Coast Marine Conservation Area. While Arch Rode in the Newport Beach Marine Conservation Area sections of the refuge are within high visitor use areas (Little Corona Tide Pools) and have exhibited declines in biodiversity related to public use as well as natural processes, the downcoast section of the refuge in the vicinity of Cameo Shores is relatively inaccessible and exhibits less human -use disturbances. The beach is fronted by a sandstone bluff mixed with native coastal scrub and introduced vegetation. Intertidal areas consist of platform intertidal reefs and pocket sandy beaches, with conspicuous offshore rocks, stacks, and arches. Subtidally, the seafloor is a mixture of sand bottom and reefs. The siltstone reefs extend seaward of the limits of the refuge to depths of about 50 ft. Numerous types of plants, invertebrates, fishes, and seabirds occur within the limits of the refuge, and marine mammals (sea lions, bottlenose dolphin, and gray whales) will occasionally pass through. Tide pools use at Little Corona is managed by the City's tide pool ranger program, which includes docent -led tours of more than 3,000 students annually. Runoff from the surrounding watershed and streets enter the refuge at several points, the largest being Buck Gully, which drains across the sandy beach into the refuge. This runoff consists of various pollutants, such as fecal material from pets, oil and grease, fertilizers, and other urban -based pollutants. In addition, Buck Gully runoff contributes to high- suspended sediment loads to the refuge, CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -26 particularly during years of high rainfall and runoff, which increases water turbidity and reduces submarine light levels. Water quality in the refuge is also likely influenced by the quality of the tidal waters flushed from Newport Bay on the outgoing tides, which tend to move downcoast oriented longshore currents. Heavy human use of the refuge has a major impact on the refuge's intertidal marine resources, resulting from illegal collecting and trampling of intertidal plants and invertebrates. Parry boats and commercial and sport fishing vessels, as well as skin divers and scuba divers frequent the waters of the refuge for fishing and collecting. Commercial lobster fishermen also utilize the nearshore reefs within the refuge. These activities have a potential to reduce the productivity of the nearshore fishery. The Irvine Coast Marine Conservation Area will expand to include the Newport Beach Marine Conservation Area and parts of the Laguna Beach Marine Conservation Area, and will be named the Crystal Cove State Marine Reserve under the Marine Life Protection Act (MLPA). The goal of the MLPA (Chapter 1015, Statutes of 1999) is to set up a system for evaluating and coordinating Marine Protected Areas (MPAs) in the state. The MLPA states that "marine life reserves" are essential elements of an MPA system because they "protect habitat and ecosystems, conserve biological diversity, provide a sanctuary for fish and other sea life, enhance recreational and educational opportunities, provide a reference point against which scientists can measure changes elsewhere in the marine environment, and may help rebuild depleted fisheries." The CDFG is required to develop a comprehensive master plan that combines ecosystem management with protection and public outreach for the state's MPAs, including the Newport Beach Marine Conservation Area. Under state marine reserve status, commercial and recreational fishing could be further restricted or prohibited to protect marine resources. Study Area No. 12: Castaways The 23.3 -acre Castaways ESA is located east of Dover Drive and south of Castaways Lane along Upper Newport Bay. A church and offices are located to the north, residential developments are located immediately west and Lower Castaways is located between the study area and the Coast Highway Bridge. Several trails cross throughout the site and can be accessed via Castaways Lane. The Castaways site is designated as a view park. The existing trail system encourages and directs the public to locations where the views of the coast, harbor and bay can be enjoyed with minimal impacts to the natural habitats. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -27 The Castaways site is characterized by four plant communities: southern willow scrub, Diegan coastal sage scrub (a restoration area), southern coastal bluff scrub, and non - native grassland. The center of the site is characterized by non - native grassland, which comprises the majority of the site. Plant species associated with this community include black mustard, Russian thistle, and Bermuda grass (Cynodon dactylon). Several dirt trails and paved routes transect the parcel. Coastal duff scrub at Castaways A drainage runs north -to -south from the church parking lot parallel to Dover Drive. This drainage is dominated by native plant species that are characteristic of southern willow scrub communities including willows, mule fat, western sycamore, cattail, and Mexican elderberry. A second ephemeral drainage runs east -to -west from the hilltop near Dover Drive. This feature supports mainly upland and non- native vegetation including Brazilian pepper tree, Peruvian pepper tree, acacia, eucalyptus, myoporum, tree tobacco, and lemonadeberry. The eastern portion of the site located along the east - facing slopes that overlook the bay support southern coastal bluff scrub vegetation. Saltbush, tree lupine, prickly pear, coyote brush, California buckwheat, and coastal goldenbush, and California bush sunflower dominate the vegetative cover. The bluff area is fenced and protected from direct disturbance. Bluff habitat within this study area is continuous with the bluff habitat that stretches north to Polaris Drive. A Diegan coastal sage scrub restoration area is located within the northwest portion of the parcel, immediately east of the riparian area. Plant species associated with this area include California sagebrush, coyote brush, California buckwheat, black sage (Salvia mellifera), and coastal goldenbush. The Diegan coastal sage scrub restoration area is the first phase of Castaways Park Revegetation Project. The project will remove the non - native and ruderal vegetation and replace it with new native vegetation to create a view park for passive recreation and nature observation. Potential impacts to the natural habitats in this study area include increased human activity, ambient noise, invasive species, and uncontrolled public access. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -28 Studv Area No.13: Newport Harbor Entrance Channel Kelp Beds The giant kelp (Macrocystis pyrifera) bed within the Newport Harbor Entrance Channel is one of the only giant kelp bed habitats currently existing between Seal Beach and South Orange County. Giant kelp beds, once found abundantly along the coastline between Corona del Mar and Laguna Beach are now extremely sparse. Warming trends, El Nino storm events, ecological imbalances due to over fishing, and Giant kelp bed habitat atNewportHarborEntrance extensive grading of lands around drainages adjacent to kelp beds that increase suspended sediment loads to the ocean are important contributors to the decline of kelp beds in southern California and have likely resulted in the decline of kelp beds within the Newport Beach Marine Conservation Area and the Irvine Coast Marine Conservation Area /Crystal Cove State Park. Giant kelp currently is rare within these refuges. Giant kelp reforestation is being attempted in Crystal Cove State Underwater Park. However, it is still too early to evaluate the success of this project. Occurring along nearly half of the length of the west jetty and extending from depths of 10 to 30 feet, the Newport Harbor Entrance giant kelp bed, while relatively small, has maintained itself over a period of several years while other kelp beds along the Newport Beach and Laguna Beach have declined. Two separate kelp beds are present. The largest bed is located along the outermost half of the west jetty, while a second and smaller bed is located along inner third of the west jetty. The total acreage of kelp is approximately 1. 16 acres. It is a productive and viable resource and supports over 70 species of plants, invertebrates, and fishes. During subtidal reconnaissance dives of underwater habitats along the Newport coastline in 2002, the marine life associated with the Newport Harbor Entrance Channel jetty quarry rock and within the kelp bed was second only to the 200 Meter Reef, located in the Crystal Cove Underwater Park, in species richness. Dredging activity and jetty reconstruction projects have a potential to reduce the viability of the kelp beds located within the Harbor Entrance Channel. Future projects conducted within the Entrance Channel should include protection measures to avoid long -term impacts to kelp bed resources.

Continue to work within the Newport Bay Watershed Executive Committee structure to address sedimentation, nutrient loading, and bacteria and toxins from runoff. The Committee includes representatives from the cities of Costa Mesa, Huntington Beach, Irvine, Lake Forest, Newport Beach, Orange, Santa Ana, and Tustin, in addition to the Irvine Ranch Water District, the California Regional Water Quality Control Board (Santa Ana Region), the California Department of Fish and Game, the U.S. Army Corps of Engineers, the County of Orange, and the Irvine Company. The Watershed Executive Committee, in implementing four separate "total maximum daily loads" for Newport Bay, has developed and is implementing plans to control sediment, nutrients, bacteria, and toxic materials in the Bay's watershed.

Resource protection policies are not intended to prevent public agencies and private property owners from maintaining drainage courses and facilities, sedimentation basins, trails, access roads, public infrastructure, and other related facilities in a safe and effective condition with minimal impact on the environment, nor are they intended to prohibit public infrastructure when the environmental process demonstrates that adverse impacts can be mitigated, or that the benefits outweigh the adverse impacts. However, any such infrastructure installed in an ESHA or wetland must be in conformance with the uses designated in Section 30240 and Section 30233 of the Coastal Act, respectively. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -35 4.1.4 Eelgrass Meadows The flowering, marine vascular plant "eelgrass" (Zostera marina) is an important marine resource due to its nursery function for invertebrates and fishes. Eelgrass forms meadows on mudflats and subtidal sediments in bays, estuaries, and occasionally, in offshore marine sand bottom habitats. The meadows (and sub units called "beds" and "patchesl provide a habitat for Eelgrass in the Grand Canal invertebrates as a source of food and attachment, and for marine fishes that seek the shelter of the beds for protection and forage on invertebrates that colonize the eelgrass blades and sediments in and around eelgrass vegetation. Eelgrass can be found worldwide in quiet, temperate -water mud or sand habitats. In Southern California, eelgrass can be found in coastal wetlands, bays, and harbors at depths between +1 feet Mean Lower Low Water (MLLW) to about —25 feet MLLW and on nearshore coastal sand bottoms to depths of 50 to 80 feet MLLW. The conditions favorable for the growth of this plant are periods of low rainfall, runoff and sedimentation, good light penetration, optimum temperature range (50 to 68 degrees Fahrenheit), moderate dissolved oxygen concentration, limited algal growth and good water quality. Once established, eelgrass patches can expand through vegetative growth along extended rhizomes to form vast meadows. At present (2003), eelgrass is abundant in several sections of Newport Harbor and has been expanding its distribution in both Lower and Upper Newport Bay over the last several years due to favorable growing conditions, lack of heavy rainfall, minimal runoff, and more stringent water quality regulations. The lowest recorded eelgrass coverage occurred in 1993 with less than 3 acres. A 2002 survey found approximately 35 acres of eelgrass coverage. Its depth range in Newport Bay is from 0.0 ft Mean Lower Low Water (MLLW) to —28 ft. On the average, however, most eelgrass in the Bay grows to a depth of about —8 to —10 ft MLLW. It grows deepest in the Newport Harbor Entrance Channel. Eelgrass grows extensively within the Harbor Entrance Channel, where it covers approximately 20 acres of underwater sandy bottom habitat. Other sections of CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -36 Newport Bay that currently support extensive eelgrass beds include the eastern shoreline of the Bay between Carnation Cove to the Coast Guard Base, Balboa Island (and in the Grand Canal), along the eastern end of the Balboa Peninsula, around Harbor Island, within the Linda Isle Basin, and in the channels around its perimeter. Eelgrass is currently expanding its distribution. Locations where smaller beds have become established within the last few years include the southern edge of the Bayshores development, a shoal immediately south of the Coast Highway Bridge near the Swales Marina; Lido Isle, and on the north side of Lido Reach between the Bayshores community west to the Balboa Bay Club. July 2002 observations indicate eelgrass is recolonizing shallow subtidal habitat in Upper Newport Bay between the Coast Highway Bridge and Dover Shores along both sides of the Main Channel after a long -term absence. Some of the eelgrass currently growing in Newport Harbor is the result of previous eelgrass transplants conducted during dredging of the Entrance Channel in the early 1980s, and in the Grand Canal on Balboa Island in 1999. These transplant programs were conducted as mitigation for Newport Harbor projects that resulted in the loss of eelgrass habitat. A large -scale eelgrass restoration program is currently being planned for Newport Harbor by the U.S. Army Corps of Engineers, the County of Orange, and the City of Newport Beach with the goal of enhancing between 5 and 10 acres of eelgrass to the Harbor within eight I pilot project restoration sites starting in May 2004. This will add a significant amount of biological value to the Harbor. Once established, these restoration sites will be enhanced by further plantings and serve as eelgrass mitigation sites for the loss of eelgrass habitat for small harbor dredging projects (500 to 1000 cubic yards). Dredging and dock and bulkhead construction projects have a potential to impact eelgrass bed resources within several areas of Newport Bay through direct habitat loss or secondary effects of turbidity or vessel anchor scarring. However, ongoing maintenance of harbor structures and periodic dredging is essential to protect the Newport Harbor's value as a commercial and recreational resource. A comprehensive and balanced management plan is necessary in order to maintain the recreational and commercial uses of the harbor while protecting its natural marine resources (see Section 4.2.5 — Eelgrass Protection and Restoration). Policies: 4.1.4 -1. Continue to protect eelgrass meadows for their important ecological function as a nursery and foraging habitat within the Newport Bay ecosystem. 4.1.4 -2. Implement eelgrass restoration and enhancement programs in Newport Harbor. 4.1.4 -3. Site and design boardwalks, docks, piers, and other structures that CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -37 extend over the water to avoid impacts to eelgrass meadows. Encourage the use of materials that allow sunlight penetration and the growth of eelgrass. 4.1.4 -4. Provide for the protection of eelgrass meadows and mitigation of impacts to eelgrass meadows in a comprehensive harbor area management plan for Newport Bay. 4.1.4 -5. Continue to require Caulerpa protocol surveys as a condition of City approval for projects in Newport Bay and immediately notify the SCCAT when found. 4.1.5 Coastal Foredunes Dune habitats are identified by stands of dense to sparse annual and perennial herbs, grasses, or shrubs occurring on sand dunes along the coast. Dune habitat is considered a sensitive plant community and is listed as rare or threatened or is otherwise protected by the U.S. Fish and Wildlife Service, California Department of Fish and Game, California Coastal Commission, or local agencies. Loss of dune habitat as a result of coastal development is considered to be a significant environmental impact, and any potential impacts to this resource must be avoided, minimized, or compensated. Southern coastal foredune habitat on the Balboa Peninsula In Newport Beach, southern coastal foredune habitat extends southwest along the ocean side of the Balboa Peninsula from 10th Street to the tip of the peninsula. The vegetation in this community is generally sparse with overall cover ranging from 20 to 70 percent in some areas, while other areas are completely devoid of vegetation. Areas of open sand fragment this habitat. Dominant plant species include non - native species such as purple sand - verbena (Abronia umbellata), sea rocket (Cakile maritima), beach evening primrose (Camissonia cheiranthifolia), sea -fig (Carpobrotus chiliensis), hottentot fig (Carpobrotus edulis), beach morning glory (Calystegia soldanella), and beach bur (Ambrosia chamissonis). Ornamental and non -native species, likely introduced from the adjacent residences, dominate much of the southern coastal foredune habitat. Numerous residences use the beach area as an extension of their backyards. Some CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -38 residents have planted and irrigated the ornamental species, which have replaced native species in these areas. Increased human activity and uncontrolled public access also adversely impact these dune habitats, as evidenced by the numerous trails bisecting the dunes. Many areas are almost completely covered by sea -fig and hottentot fig. If dune habitat losses cannot be avoided, then mitigation programs to restore dune habitat within Newport Beach should be implemented. Policies: 4.1.5 -1. Require the removal of exotic vegetation and the restoration of native vegetation in dune habitat. 4.1.5 -2. 4.1.5 -3. Direct public access away from dune habitat areas through the use of well - defined footpaths, boardwalks, protective fencing, signage, and similar methods. 4.1.5 -4. Design and site recreation areas to avoid impacts to dune habitat areas. 4.1.5 -5. Require a coastal development permit for earthmoving beach sand in dune habitat areas. 4.1.5 -6. Limit earthmoving of beach sand in dune habitat areas to projects necessary for the protection of coastal resources and existing Iceplant encroachment into southem coastal foredunes CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4.39 4.2 Wetlands and Deepwater Areas Coastal Act policies related to wetlands and deepwater areas that are relevant to Newport Beach include the following: 30231. The bidogxucal productivity and the quality of coastal watery streams, wedards, estuaries, and lakes Appropriate to maintain optimum poptiabons of morn organisms and for the protection of human health Mall be maintained and, where feasible. restored through, among direr nests, minimizing adverse effects of waste water discharges and entraimnem, controlling runoff, preventing depletion of ground water supplies and substantial interference with surface waterflow, encouraging waste water redarnation, maintaining natural vegetation buffer areas that protect riparian habitats, and minimizing Aeration of natral streams. The Coastal Act distinguishes wetlands from other types of water areas, such as estuaries and open coastal waters. Section 30121 of the Coastal Act defines "wetlands" as 'lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes, freshwater marshes, open or closed brackish water marshes, swamps, mudflats, and fens." Therefore, the interpretation of the term "shallow water" can be used to distinguish wetlands from other submerged areas. The U.S. Fish and Wildlife Service defines the boundary between wetland and deepwater habitat as the elevation of extreme low -water of spring tide for areas subject to tidal influence. Therefore, for purposes of the Coastal Act, wetlands can be interpreted as beginning at extreme low -water of spring tide and "estuary" or 'open coastal water" is anything deeper. 4.2.1 Southern California Wetlands Wetlands are transitional lands between terrestrial and aquatic systems where the water table is usually at or near the surface or the land is often covered by shallow water during some parts of the year. Wetlands can be categorized according to specific habitat and type of vegetation. In Southern California, wetlands generally fall into four categories: estuarine wetlands, such as the Upper Newport Bay and Semeniuk Slough; freshwater marshes, which can be found in Big Canyon, Buck Gully, and San Diego Creek; riparian wetlands, which occur along creeks and streams or bodies of water; and vernal pools, which can be found on Banning Ranch. Southern California coastal wetlands and watersheds have been dramatically altered or destroyed by human activities over the past 150 years. Wetlands have been filled and rivers, streams, and creeks have been rerouted, dammed, channelized, and paved. Estimates of historic wetland acreages compiled from the literature and U.S. Coast and Geodetic Surrey maps created between 1851 and 1893 indicate a loss of 70 percent reduction in coastal wetlands in Southern California. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -40 Wetlands are recognized as very important ecosystems with the following multiple values and functions: • Biological Diversity. Wetlands provide important habitat for diverse communities of plants and animals, including federally listed threatened or endangered species. • Waterfowl Habitat. Wetlands provide the principal habitat for migratory waterfowl. California provides critical wintering habitat for millions of waterfowl migrating along the Pacific Flyway, which extends from Canada to Mexico. • Fisheries. Wetlands provide direct spawning and rearing habitats and food supply that supports both freshwater and marine fisheries. • Flood Control. Wetlands detain flood flows, reducing the size and destructiveness of floods. • Water Quality. Wetlands absorb and filter pollutants that could otherwise degrade ground water or the water quality of rivers, lakes, and estuaries. • Ground Water Recharge. Some wetlands recharge aquifers that provide urban and agricultural water supplies. • Recreation. Wetlands support a multi - million - dollar fishing, hunting, and outdoor recreation industry nationwide. The Coastal Act requires the projection of wetlands. Development or alteration of coastal wetlands is primarily regulated by Section 30233 of the Coastal Act, which provides that the diking, filling, or dredging of open coastal waters, wetlands, or estuaries may only be permitted where there is no less environmentally damaging alternative and must be restricted to a narrow range of allowable uses. The Coastal Act also requires the protection of biological productivity and quality of coastal waters, streams, wetlands, estuaries, and lakes. Water quality issues are discussed in detail in Section 4.3 (Water Quality). Two federal statutes provide the primary regulatory authority over wetlands. The Clean Water Act (Section 404(b)) regulates disposal of dredge and fill materials into waters of the United States, including all streams to their headwaters, lakes over 10 acres, and contiguous wetlands, including those above the ordinary high water mark in non -tidal waters and mean high tide in tidal waters. The River and Harbors Act of 1899 (Section 10) regulates the diking, filling, and placement of structures in navigable waterways. The U.S. Army Corps of Engineers is primarily responsible for the implementation and enforcement of rules and regulations pertaining to both sections of these statutes. The Environmental Protection CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -41 Agency, the Natural Resources Conservation Service, the National Marine Fisheries Service (NMFS), and the Fish and Wildlife Service (FWS) review applications for Section 404 permits and can provide the Corps with comments and recommendations reflecting agency concerns. Policies: 4.2.1 -1. Recognize and protect wetlands for their commercial, recreational, water quality, and habitat value. 4.2.1 -2. Protect, maintain and, where feasible, restore the biological productivity and the quality of coastal waters, streams, wetlands, estuaries, and lakes. 4.2.2 Wetland Definition and Delineation Due to semi -arid Mediterranean climate of Southern California, some wetlands can remain dry for one or more seasons. This presents problems for the identification and delineation of wetlands. Section 30121 of the Coastal Act defines "wetlands" as 'lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes, freshwater marshes, open or closed brackish water marshes, swamps, mudflats, and fens." However, a more specific definition is provided in Section 13577 (b -1) of the California Code of Regulations: "...land where the water table is at near, or above the land surface long enough to promote the formation of hydric soils or to support the growth of hydrophytes, and shall also include types of wetlands where vegetation is lacking and soil is poorly developed or absent as a result of frequent drastic fluctuations of surface water levels, wave action, water flow, turbidity or high concentration of salts or other substances in the substrate. Such wetlands can be recognized by the presence of surface water or saturated substrate at some during each year and their location within, or adjacent to vegetated wetland or deepwater habitats." The boundary line between the wetland and adjacent upland area is determined by the extent of one or more key wetland characteristics: hydrology (frequency, duration, and timing of inundation or saturation), hydric soils (soil with characteristics resulting from prolonged saturation), and hydrophytic vegetation (plants adapted to life in water, or in periodically flooded and /or saturated anaerobic soils). Positive wetland indicators of all three characteristics are normally present in wetlands. However, the presence of only one of these characteristics (e.g., hydrology, hydric soils, or hydrophytic vegetation) is needed for an area to qualify as a wetland, pursuant to the California Code of Regulations. Hydrology is the key characteristic because it drives the formation of hydric soils and allows hydrophytic vegetation to establish dominance. However, hydrology is CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -42 the most difficult of the three wetland characteristics to quantify. Many of the hydrology indicators are subjective and often it is difficult to determine the timing and duration of hydrology without visual observation. Therefore, the Coastal Commission considers a predominance of hydrophytes or a predominance of hydric soils as evidence that the land was "wet enough long enough" to develop wetland characteristics. Although vegetation is often the most readily observed parameter, sole reliance on vegetation or either of the other parameters as the determinant of wetlands can sometimes be misleading. Many plant species can grow successfully in both wetlands and non - wetlands, and hydrophytic vegetation and hydric soils may persist for decades following alteration of hydrology that will render an area a non - wetland. In situations where ambiguities in wetland characteristics exist, the judgment of a qualified biologist may be required to determine whether an area meets the definition of a wetland. The presence or absence of more than one parameter may be considered along with other factors, such as recent precipitation patterns, topography, drainage patterns, and adjacency to identified wetlands. Policies: 4.2.2 -1. Define wetlands as areas where the water table is at, near, or above the land surface long enough to bring about the formation of hydric soils or to support the growth of hydrophytes. Such wetlands can include areas where vegetation is lacking and soil is poorly developed or absent as a result of frequent drastic fluctuations of surface water levels, wave action, water flow, turbidity or high concentration of salts or other substances in the substrate. Wetlands do not include areas which in normal rainfall years are permanently submerged (streams, lakes, ponds and impoundments), nor marine or estuarine areas below extreme low water of spring tides, nor vernally wet areas where the soils are not hydric. 4.2.2 -2. Where ambiguities in wetland characteristics exist, the presence or absence of more than one wetland parameter may be considered along with other factors, including recent precipitation patterns, topography, drainage patterns, and adjacency to identified wetlands, to determine whether an area meets the definition of a wetland and to delineate wetland boundaries. 4.2.2 -3. Require a surrey and analysis with the delineation of all wetland areas when the initial site surrey indicates the presence or potential for wetland species or indicators.

Newport Bay's main source of fresh water is San Diego Creek. Historically only about 15 square miles of land drained CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -44 into the bay via San Diego Creek. However, San Diego Creek was channelized in 1968 so that peak floods and sediment could be efficiently routed to the bay. This increased the drainage area to about 118 square miles. In 1969, heavy storm runoff poured hundreds of thousands of tons of sediment into the bay. Subsequent storm season sedimentation events in 1978 and 1980 caused shallowing of the Upper Bay. Intertidal saltmarsh vegetation became established and expanded rapidly. This would have eventually filled the bay with sediment and turned it into a meadow. San Diego Creek near Back Bay Drive In 1985, 85 acres of the Upper Bay were dredged out to create the Unit I Sediment Control Basin (depths —3 to —7 feet MSL). A second dredging project in 1988 created the 37 -acre Unit 11 Sediment Control Basin, just south of the Main Dike (depth —14 feet MSL). Both basins have worked well, collecting large volumes of coarser grained sediment from periodic flood runoff, principally down San Diego Creek. However, these require extensive on -going maintenance dredging. The last major dredging activity in the bay occurred in 1998 -99. This project cleared about 900,000 cubic yards of sediment from the bay. As the 1998 -99 project was completed, Newport Beach, Orange County, the Irvine Ranch Water District, the Santa Ana Regional Water Quality Control Board, The Irvine Company, the California Department of Fish and Game, and the watershed cities of Irvine, Costa Mesa, Tustin, Lake Forest, and Laguna Woods, began planning a larger, more significant project with the U.S. Army Corps of Engineers to complete the restoration of the Upper Newport Bay. The Upper Newport Bay Ecosystem Restoration Project was developed to restore and maintain tidal movement in the bay. The project would dredge more than 2.7 million cubic yards from the Upper Bay, restore deteriorated habitat, increase blue - water views, move the Least Tern islands, and open up several island channels in mid -Upper Bay. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -45 Lower Newport Bay /Harbor Since Lower Newport Bay was dredged between 1934 and 1936 to create the navigation channels, the U.S. Army Corps of Engineers has dredged the Lower Bay on only three occasions. In 1941 they deepened the turning basin at the west end of the harbor (Lido Village area). In 1981, 85,000 cubic yards of sand were dredged from the harbor entrance adjacent to Big Corona. In 1998, 204,000 cubic meters of sediment are removed from just The Turning Basin below the Pacific Coast Highway Bridge at the junction of the Main and Upper Bay Channels in the area of Harbor and Linda Islands. Except for these three projects, maintenance dredging by the Corps to maintain the federally authorized harbor channels has not been undertaken. As part of their maintenance responsibility, the Corps does annual Newport Bay condition surveys of the navigational channels to ascertain whether the channels are at or near their design depth and whether additional dredging is necessary. There are approximately 1,200 harbor permits for both residential and commercial docks within Newport Harbor. It is general policy that the responsibility for dredging around and under private docks rests with the private property owner. In the past, the City has secured a Regional General Permit in order to expedite property owners' permit processing with the Corps and the California Coastal Commission. The Regional General Permits' term is typically 5 to 10 years. Policies: 4.2.3 -1. Permit the diking, filling, or dredging of open coastal waters, wetlands, estuaries, and lakes in accordance with other applicable provisions of the LCP, where there is no feasible less environmentally damaging alternative, and where feasible mitigation measures have been provided to minimize adverse environmental effects and limited to the following: A. Construction or expansion of port/marine facilities. B. Construction or expansion of coastal- dependent industrial CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -46 facilities, including commercial fishing facilities, haul -out boat yards, and commercial ferry facilities. C. In wetland areas only, entrance channels for new or expanded boating facilities; and in a degraded wetland, identified by the Department of Fish and Game pursuant to subdivision (b) of Section 30411, for boating facilities if, in conjunction with such boating facilities, a substantial portion of the degraded wetland is restored and maintained as a biologically productive wetland. The size of the wetland area used for boating facilities, including berthing space, turning basins, necessary navigation channels, and any necessary support service facilities shall not exceed 25 percent of the degraded wetland. D. In open coastal waters, other than wetlands, including estuaries, new or expanded boating facilities, including slips, access ramps, piers, marinas, recreational boating, launching ramps, haul -out boat yards, and pleasure ferries, and the placement of structural pilings for public recreational piers that provide public access and recreational opportunities. E. Maintenance of existing and restoration of previously dredged depths in navigational channels, turning basins, vessel berthing, anchorage, and mooring areas, and boat launching ramps. The most recently updated U.S. Army Corps of Engineers maps shall be used to establish existing Newport Bay depths. F. Incidental public service purposes which temporarily impact the resources of the area, such as burying cables and pipes, inspection of piers, and maintenance of existing intake and outfall lines. G. Sand extraction for restoring beaches, except in environmentally sensitive areas. H. Restoration purposes. I. Nature study, aquaculture, or similar resource - dependent activities. J. In the Upper Newport Bay Marine Park, permit dredging, diking, or filling only for the purposes of wetland restoration, CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -47 nature study, or to enhance the habitat values of environmentally sensitive areas. 4.2.3 -2. Continue support of the Upper Newport Bay Ecosystem Restoration Project to restore the Upper Newport Bay to its optimal ecosystem. 4.2.3 -3. Secure federal funding for the Upper Newport Bay Ecosystem Restoration Project. 4.2.3 -4. Secure permanent use designation for the LA -3 sediment disposal site for future dredging projects. 4.2.3 -5. Require the following mitigation measures for dredging projects in the Upper Newport Bay Marine Park: A. Dredging and spoils disposal must be planned and carried out to limit turbidity and to avoid significant disruption to marine and wildlife habitats and water circulation. B. Maintenance dredging shall be encouraged where the dredging enhances commercial or recreational use of the Bay. When dredged material is of an appropriate grain size and grain percentage, this material may be used to restore or replace natural sandy sloping beaches in order to retain the current profiles of Newport Bay. Maintenance dredging activity shall have the approval of the U.S. Army Corps of Engineers and shall meet applicable U.S. Environmental Protection Agency standards. C. Dredged material not suitable for beach nourishment shall be disposed of offshore at a designated U.S. Environmental Protection Agency disposal site. D. Temporary dewatering of dredged spoils may be authorized within the Bay's drainage if adequate erosion controls are provided and the spoils are removed. A bond or a contractual arrangement shall be a precondition to dredging of the material, and final disposal of the dewatered material on the approved dump site shall be accomplished within the time period specified in the permit. E. Dredged spoils shall not be used to fill riparian areas, wetlands, or natural canyons. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -48 F. Other mitigation measures may include opening areas to tidal action, removing dikes, improving tidal flushing, restoring salt marsh or eelgrass vegetation, or other restoration measures. G. Dredge spoils suitable for beach nourishment should be transported for such purposes to appropriate beaches or into suitable longshore current systems provided that the placement is permitted by a Section 404 permit. 4.2.3 -6. Continue to cooperate with the U.S. Army Corps of Engineers in their maintenance and delineation of federal navigational channels at Newport Harbor in the interest in providing navigation and safety. 4.2.3 -7. Continue to secure Regional General Permits through the U.S. Army Corps of Engineers and the California Coastal Commission to expedite permit processing for residential and commercial dock owners in the Bay. 4.2.3 -8. Issue permits authorizing maintenance dredging under and around residential piers and floats subject to compliance with all conditions to the current Regional General Permit, including grain size requirements, availability of suitable dredge disposal site, and periodic bioassays. 4.2.3 -9. Require the following minimum mitigation measures if a project involves diking or filling of a wetland: A. If an appropriate restoration site is available, the applicant shall submit a detailed restoration plan which includes provisions for purchase and restoration of an equivalent area of equal or greater biological productivity and dedication of the land to a public agency or otherwise permanently restricts its use for open space purposes. The site shall be purchased before the dike or fill development may proceed. B. The applicant may, in some cases, be permitted to open equivalent areas to tidal action or provide other sources of surface water. This method of mitigation would be appropriate if the applicant already owned filled, diked areas which themselves were not environmentally sensitive habitat areas but would become so, if such areas were opened to tidal action or provided with other sources of surface water. C. However, if no appropriate sites under options (A) and (B) are available, the applicant shall pay an in -lieu fee of sufficient CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -49 value to an appropriate public agency for the purchase and restoration of an area of equivalent productive value, or equivalent surface area. This third option would be allowed only if the applicant is unable to find a willing seller of a potential restoration site. The public agency may also face difficulties in acquiring appropriate sites even though it has the ability to condemn property. Thus, the in -lieu fee shall reflect the additional costs of acquisition, including litigation, as well as the cost of restoration. If the public agency's restoration project is not already approved by the City, the public agency may need to be a co- applicant for a permit to provide adequate assurance that conditions can be imposed to assure that the purchase of the mitigation site shall occur prior to issuance of the permit. In addition, such restoration must occur in the same general region (e.g., within the same estuary) where the fill occurred. 4.2.3 -10. All preferred restoration programs would remove fill from a formerly productive wetland or estuary that is now biologically unproductive dry land and would establish a tidal prism necessary to assure adequate flushing. Since restoration projects necessarily involve many uncertainties, restoration should precede the diking or filling project. At a minimum, permits will be conditioned to assure that restoration will occur simultaneously with project construction. Restoration and management plans shall be submitted with the permit application. 4.2.3 -11. Require that any project that includes diking, filling or dredging of a wetland or estuary must maintain the functional capacity of the wetland or estuary. Functional capacity means the ability of the wetland or estuary to be self- sustaining and to maintain natural species diversity. In order to establish that the functional capacity is being maintained, the applicant must demonstrate all of the following: A. That the project does not alter presently occurring plant and animal populations in the ecosystem in a manner that would impair the long -term stability of the ecosystem; i.e., natural species diversity, abundance, and composition are essentially unchanged as a result of the project. B. That the project does not harm or destroy a species or habitat that is rare or endangered. C. That the project does not harm a species or habitat that is CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -50 essential to the natural biological functioning of the wetland or estuary. D. That the project does not significantly reduce consumptive (e.g., fishing, aquaculture and hunting) or non - consumptive (e.g., water quality and research opportunity) values of the wetland or estuarine ecosystem. 4.2.3 -12. Require that new developments on the waterfront to design and site docking facilities in relationship to the usable water area. 4.2.3 -13. Design and site all structures permitted to encroach into open coastal waters, wetlands, and estuaries to harmonize with the natural appearance of the surrounding area. 4.2.3 -14. Continue to limit residential and commercial structures permitted to encroach beyond the bulkhead line to piers and docks used exclusively for berthing of vessels. However, this policy shall not be construed to allow development that requires the filling of open coastal waters, wetlands or estuaries that would require mitigation for the loss of valuable habitat in order to place structures closer to the bulkhead line or create usable land areas. 4.2.3 -15. Require restoration plans to be reviewed and approved by a qualified professional prior to accepting sites for mitigation. Balboa Island Channel CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -51 4.2.4 Dredge Spoils Disposal Coastal Act policies related to dredge spoils disposal that are relevant to Newport Beach include the following: 30233. (b) Dredging and spoils disposal shall be panned and tamed out to avoid significant disruption to marine and wildlife habitats and water armilatinn. Dredge spoils suitable for beach replenishment should be transported for such puposes to appropriate beaches or Into stitable lorgshere carat systems. (d) Erosion control and flood control facilities consbucted an watercouses can impede the movemat of sediment and nurients which would otherwise be carded by storm runoff into coastal waters. To facilitate the condntred delivery Of these sediments to the I toral zone. whenever feasible, the ntaewial removed from these facilities may be placed at appropriate points on the shorine in accordance with odw applicable provisions of this division, where feasible mitigation measures have been provided to n inimize adverse environmental effects. Aspects that shall be considered before isstdng a coastal development permit for such puposes are the method of placement, time of year of placement, and senstivty of the placement area. Section 30233(b) of the Coastal Act requires that dredge spoils be disposed of in a manner that avoids disruption to habitats. The selection of a disposal site for dredged sediments is dependent upon the physical and chemical characteristics of the material. Material free of chemical contamination and consisting primarily of sand of an acceptable grain size (usually approximately 80 percent sand) is generally suitable for beach nourishment and placed on appropriate beaches or within suitable longshore currents. Material of appropriate grain size Dredging project in Balboa Island Channel and with minimal contamination may be disposed of at unconfined, openwater disposal sites authorized by the U.S. Environmental Protection Agency (EPA) and U.S. Army Corps of Engineers. Dredged material that is physically suitable, but is chemically unsuitable for aquatic disposal due to of elevated levels of certain contaminants, may be used as fill, or in certain wetland construction and habitat improvement projects, provided the contaminated materials are confined (e.g., parking lots, container piers, etc.). Periodic maintenance dredging and habitat restoration projects in Newport Bay require an environmentally acceptable disposal site. However, due to grain size incompatibility, most of this material will not be suitable for beach nourishment. Upland disposal is generally cost - prohibitive and harbor landfill and habitat improvement projects occur too infrequently to be a reliable disposal option. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -52 Therefore, the most practical solution is a nearby offshore disposal site. The LA -3 Ocean Dredged Material Disposal Site ( ODMDS) is located approximately 4 miles off the coast of Newport Beach. The LA -3 site has been historically used for the disposal of dredged material from Newport Bay and for material not suitable for beach nourishment at Newport Beach due to grain size incompatibility. The LA -3 ODMDS was designated as an interim site for the disposal of dredged material Disposal of dredge material off of West Newport by the EPA. Securing LA -3 O DMS as a permanently designated disposal site is therefore essential to the projection of Newport Bay as a commercial, recreational and ecological resource. Monitoring dredging projects within the region can provide opportunities to reduce • disposal costs and utilize dredge spoils for beach nourishment. By placing the sediment on the beach, offshore disposal costs are eliminated and the nourishment project provides a tangible benefit from the dredging operation. In 1992, a nourishment project was devised to reduce disposal costs and to take • advantage of the large quantities of beach -grade sand from the Lower Santa Ana River Flood Control Channel Expansion Project. Nearly 1.3 million cubic yards of dredged material were deposited offshore of Newport Beach, which migrated to West Newport beaches under the influence of waves and currents. Policies: 4.2.4 -1. Cooperate with the U.S. Environmental Protection Agency and the U.S. Army Corps of Engineers to secure LA -3 ODMDS as a permanently designated disposal site. 4.2.4 -2. Monitor dredging projects within the region to identify opportunities to reduce disposal costs and utilize dredge spoils for beach nourishment. 4.2.4 -3. Participate in regional sediment management by maintaining records of the number of channelized streams, miles of channelization in streams, volumes of sediment extracted from stream channels and debris basins, and the grain size distribution of the extracted sediments. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -53 4.2.5 Eelgrass Protection and Restoration Eelgrass (Zostera marina) is an important underwater plant that is indicative of and supports a healthy and diverse marine environment (see Section 4.1.4 - Eelgrass Meadows). Dredging projects in the Lower Bay have the potential to impact eelgrass bed resources. The loss of eelgrass as a development is a significant result of coastal considered to be environmental impact, and any potential impacts to this resource must be avoided, minimized, Or mltlgated. Eelgrass in Newport Harbor Entrance Channel Currently, mitigation requires an expensive and time - consuming procedure that requires the eelgrass to be replanted, monitored, and maintained per the Southern Calithmia Eelgrass Mitigation Policy. This policy was developed in 1991 by the National Marine Fisheries Service, U.S. Fish and Wildlife Service, and the California Department of Fish and Game in order to standardize and maintain a consistent policy regarding mitigating adverse impacts to eelgrass resources. The policy typically requires that for every square foot of eelgrass removed, 1.2 square feet must be planted and maintained. Eelgrass period of 5 years for most projects. mitigation monitoring is required for a The City, the County of Orange, and the U.S. Army Corps of Engineers have worked with various resource agencies (including the U.S. Fish and Wildlife Service, the National Marine Fisheries Service, and the California Department of Fish and Game) to develop a plan whereby the City and the County of Orange would establish, monitor, and maintain eelgrass beds. The eelgrass restoration program is intended to enhance between 5 and 10 acres of eelgrass to the Harbor within eight pilot restoration sites. Once deemed successful, these eight sites will serve as eelgrass mitigation sites for City projects and as a mitigation bank from which eelgrass mitigation credits will be issued to private property owners for eelgrass removal resulting from dock and channel dredging projects. The Southern Calithmia Eelgrass Mitigation Policy provides detailed procedures for mitigating adverse impacts to eelgrass resources. However, the policy contains no provision for post- recovery conditions. The policy was drafted at a time when eelgrass coverage was near a low point in Newport Harbor. At present (2003), eelgrass is abundant in several sections of Newport Harbor and has been expanding its distribution in both Lower and Upper Newport Bay. The policy CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -54 requires all eelgrass patches to be protected or replaced, regardless of its size, location, or habitat value or the extent of eelgrass coverage within the harbor. Eelgrass protection, mitigation, and monitoring complicate and substantially increase the cost of dredging maintenance projects, which are essential to protecting the Newport Harbor's value as a commercial and recreational resource. An eelgrass acreage baseline for Newport Harbor is needed. The baseline would be the minimum acreage, based on the distribution, density, and productivity, necessary for eelgrass meadows to fulfill their ecological function. Once the baseline is determined, projects may be granted exemptions to the Southern California Eelgrass Mitigation Policy mitigation requirements, provided the eelgrass acreage baseline is maintained. The National Marine Fisheries Newport Channel Service, as the lead agency, would need to incorporate such a provision into Southern Califomia Eelgrass Mitigation Policy and the U.S. Army Corps of Engineers, the Coastal Commission, and the Santa Ana Regional Water Quality Control Board to incorporate the provision into the City's Regional General Permit and into any individual property owner's dredging or dock construction permit that qualifies under future applications. The establishment of a baseline for eelgrass meadows will serve to protect their important ecological function while allowing the periodic dredging that is essential to protect the Newport Harbor's value as a commercial and recreational resource. Policies: 4.2.5 -1. Avoid impacts to eelgrass (Zostera marina) to the greatest extent possible. Mitigate losses of eelgrass at a 1.2 to 1 mitigation ratio and in accordance with the Southem Califomia Eelgrass Mitigation Policy. Encourage the restoration of eelgrass throughout Newport Harbor where feasible. 4.2.5 -2. When eelgrass planted in a mitigation area migrates into adjacent areas that did not previously contain eelgrass, further mitigation for dredging those adjacent areas shall not be required. 4.2.5 -3. Continue to cooperate with the County of Orange, the U.S. Army Corps of Engineers, and resource agencies to establish eelgrass CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -55 restoration sites. 4.2.5 -4. Allow successful eelgrass restoration sites to serve as mitigation sites for City projects and as a mitigation bank from which eelgrass mitigation credits will be issued to private property owners for eelgrass removal resulting from dock and channel dredging projects. 4.2.5 -5. Conduct studies to establish an eelgrass acreage baseline for Newport Harbor based on the distribution, density, and productivity, necessary for eelgrass meadows to fulfill their ecological function. 4.2.5 -6. Cooperate with the National Marine Fisheries Service to incorporate a provision into the Southem California Eelgrass Mitigation Policy that would allow exemptions to mitigation requirements for harbor maintenance projects for provided the eelgrass acreage baseline is maintained. 4.2.5 -7. Cooperate with the U.S. Army Corps of Engineers, the Coastal Commission, and the Santa Ana Regional Water Quality Control Board to incorporate the eelgrass acreage baseline exemption provision into the City's Regional General Permit and into any individual property owner's dredging or dock construction permit that qualifies under future applications. 4.2.5 -8. Perform periodic surveys of the distribution of eelgrass in Newport Bay in cooperation with the National Marine Fisheries Services to insure that the eelgrass baseline is maintained. 4.2.5 -9. Cooperate with resource agencies to conduct a comprehensive evaluation of biological, recreational, commercial and aquatic resources of Newport Harbor and to develop a Harbor Area Management Plan (RAMP) that will maintain all of the intended beneficial uses of the harbor. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -56 4.3 Water Quality Coastal Act policies related to water quality that are relevant to Newport Beach include the following: 30230. Marine resources shall be maintained. enhanced, and. where feasible, restored. Special protection shall be given to areas and species of special biological or economic significance. Uses of the marine environment shall be carried out in a manner that will sustain the biological productivity of coastal waters and that will maintain healthy populations of all species of marine organisms adequate for WV -term commercial, recreational, scientific, and educational purposes. 30231. The biological productivity and the quality of coastal waters, streams, wetlands. estuaries, and lakes appropriate to maintain optimum populations of marine organisms and for the protection of human heath shall be maintained and, where feasible. restored through. among other means. minir sang adverse effects of waste water discharges and entrainment, controlling runoff, preventing depletion of ground water Supplies and substantial interference with surface watertlow. encouraging waste water reclamation, maintaining natural vegetation buffer areas that protect riparian habitats, and minirrizatg alteration of natural streams. 30232. Protection against the spillage of crude od, gas, petroleum products, or hazardous substances shall be provided in relation to any development or transportation of such materials. Effective containment and cleanup facilities and procedures shall be provided for accidental spills that do occur Newport Beach's greatest resources are its coastline and bay. They have drawn people here since prehistoric times, were the preeminent factor in the community's founding and development, and continue to provide the community with employment, recreation, natural habitat, and a beautiful physical setting. With these great gifts come great responsibilities for the protection and enhancement of these resources. Newport Beach has traditionally cared greatly about the quality of the water in Shoretne near Balboa Pier Newport Bay and along the ocean shoreline and has embarked on a number of programs to improve the water quality. 4.3.1 TMDLs Newport Bay receives urban runoff from the Newport Bay watershed, an area that includes unincorporated County territory and areas within the cities of Costa Mesa, Laguna Woods, Lake Forest, Irvine, Newport Beach, Orange, Santa Ana, and Tustin. The primary tributaries to Newport Bay are the Santa Ana /Delhi Channel (draining the cities of Costa Mesa and Santa Ana), San Diego Creek (draining the cities of Irvine, Laguna Woods, Lake Forest, portions of Newport Beach, Orange, and Tustin), and Big Canyon Creek (draining Newport Beach). CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -57 Newport Bay is designated as "water quality- limited" for four impairments under the Federal Clean Water Act's Section 303(d) List, meaning that it is "not reasonably expected to attain or maintain water quality standards" due to these impairments without additional regulation. As a water quality- limited body, the California Regional Water Quality Control Board, Santa Ana Region ( "Regional Board ") and the U.S. Environmental Protection Agency ( "U.S. EPA ") have developed total maximum daily loads ( "TMDLs ") for the following substances: sediment, nutrients, fecal coliform, and toxic pollutants. The Board included these TMDLs in the Regional Board's Basin Plan for the region. Sediment. Adopted on October 9, 1998, the Sediment TMDL requires local partners (stakeholders in the watershed) to survey the Bay regularly and to reduce annual sediment coming into the Bay from 250,000 cubic yards to 125,000 cubic yards (a 50% reduction) by 2008. The TMDL's goal is to reduce dredging frequency in Upper Newport Bay to once every 20 years. Part of the TMDL includes a proposed Upper Newport Bay Ecosystem Restoration Project, a U.S. Army Corps of Engineers -led ecosystem restoration project that attempts to restore the Upper Bay to its optimal habitat. Nutrients. Approved by U.S. EPA on April 16, 1999, the Nutrient TMDL limits nitrogen and phosphorus inputs to the Bay. The Nutrient TMDL attempts to reduce the annual loading of nitrogen by 50% -- from 1,400 pounds per day today to approximately 850 to 802 pounds per day at San Diego Creek — by 2012. Phosphorus loading must fall from 86,912 pounds per year in 2002 to 62,080 pounds by 2007. Fecal Coliform. Approved in December 1999, the Fecal Coliform TMDL attempts to reduce the amount of fecal coliform inputs to the Bay enough to make the Bay meet water contact recreation (REC1) standards (swimming, wading, surfing) by 2014 and shellfish harvesting (SHEL) standards (where waters support shellfish acceptable for human consumption) by 2020. Toxic Pollutants. Adopted by U.S. EPA on June 14, 2002, the Toxic Pollutants TMDL addresses Bay inputs like heavy metals (chromium, copper, lead, cadmium, zinc) and priority organics like (endosulfan, DDT, Chlordane, PCBs, Toxaphene, diazinon, chlorpyriphos, more). It may lead to the reduction or elimination of pesticide use by residents, businesses, and municipal services in the watershed. Some controls will be placed on heavy metals. The Toxic Pollutants TMDL also addresses existing toxic deposits in sediments in Rhine Channel and other areas in the Lower Bay. To implement the obligations of the TMDLs and to partner on related water quality issues, Newport Beach, the Regional Board, the California Department of Fish and Game, the County of Orange, and the other cities in the Newport Bay watershed CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -58 have established the Newport Bay Watershed Executive Committee as advised by the Watershed Management Committee (WEC and WMC). The WMC typically meets quarterly to comply with the TMDLs established by the Regional Board. Generally, all the TMDLs established by the Regional Board require that watershed- based solutions be developed by the watershed stakeholders, and then the stakeholders jointly fund and implement these projects throughout the watershed. Policies: 4.3.1 -1. Continue to develop and implement the TMDLs established by the Regional Board and guided by the Newport Bay Watershed Executive Committee (WEC). 4.3.1 -2. Secure funding for the Upper Newport Bay Ecosystem Restoration Project. 4.3.1 -3. Establish and protect a long -term funding source for the regular dredging of Upper Newport Bay (including the Robinson - Skinner Annuity) and dredging of the Lower Newport Bay so that the City and its watershed partners achieve the goals and directives of the Sediment and Nutrient TMDLs adopted for Newport Bay. 4.3.1 -4. Preserve, or where feasible, restore natural hydrologic conditions such that downstream erosion, natural sedimentation rates, surface flow, and groundwater recharge function near natural equilibrium states. 4.3.1 -5. Require development on steep slopes or steep slopes with erosive soils to implement structural best management practices (BMPs) to prevent or minimize erosion. 4.3.1 -6. Require grading /erosion control plans to include soil stabilization on graded or disturbed areas. 4.3.1 -7. Require measures be taken during construction to limit land disturbance activities such as clearing and grading, limiting cut -and- fill to reduce erosion and sediment loss, and avoiding steep slopes, unstable areas, and erosive soils. Require construction to minimize disturbance of natural vegetation, including significant trees, native vegetation, root structures, and other physical or biological features important for preventing erosion or sedimentation. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -59 4.3.2 NPDES The City of Newport Beach operates a municipal separate storm sewer system (MS4). The City's MS4 is permitted by the Regional Board under the National Pollutant Discharge Elimination System ( NPDES). The City's MS4 permit is extensive in its obligation to keep waterways clean by reducing or eliminating contaminants from stormwater and dry- weather runoff. MS4 permits require an aggressive Water Quality Ordinance (Ord. 97 -26), specific Catch basin screens andRters municipal practices to maintain city facilities like the MS4, and the use of "best management practices" (BMPs) in many residential, commercial, and development - related activities to further cut runoff. MS4 permits also require local agencies to cooperatively develop a public education campaign to let more people know about what they can do at home and at work to protect water quality. Policies: 4.3.2 -1. Promote pollution prevention and elimination methods that minimize the introduction of pollutants into coastal waters, as well as the generation and impacts of dry weather and polluted runoff. 4.3.2 -2. Require that development not result in the degradation of coastal waters (including the ocean, estuaries and lakes) caused by changes to the hydrologic landscape. 4.3.2 -3. Support and participate in watershed -based runoff reduction and other planning efforts with the Regional Board, the County of Orange, and upstream cities. 4.3.2 -4. Continue to update and enforce the Newport Beach Water Quality Ordinance. 4.3.2 -5. Develop and maintain a water quality checklist to be used in the permit review process to assess potential water quality impacts. 4.3.2 -6. Implement and improve upon best management practices (BMPs) for residences, businesses, new development and significant redevelopment, and City operations. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -60 4.3.2 -7. Incorporate BMPs into the project design in the following progression: • Site Design BMPs. • Source Control BMPs. Treatment Control BMPs. Include site design and source control BMPs in all developments. When the combination of site design and source control BMPs are not sufficient to protect water quality as required by the LCP or Coastal Act, structural treatment BMPs will be implemented along with site design and source control measures. 4.3.2 -8. To the maximum extent practicable, runoff should be retained on private property to prevent the transport of bacteria, pesticides, fertilizers, pet waste, oil, engine coolant, gasoline, hydrocarbons, brake dust, tire residue, and other pollutants into recreational waters. 4.3.2 -9. To the maximum extent practicable, limit the use of curb drains to avoid conveying runoff directly to the City's street drainage system without the benefit of absorption by permeable surfaces and natural treatments such as landscaped areas and planters. 4.3.2 -10. Provide storm drain stenciling and signage for new storm drain construction in order to discourage dumping into drains. 4.3.2 -11. Require new development to minimize the creation of and increases in impervious surfaces, especially directly connected impervious areas, to the maximum extent practicable. Require redevelopment to increase area of pervious surfaces, where feasible. 4.3.2 -12. Require development to protect the absorption, purification, and retention functions of natural drainage systems that exist on the site, to the maximum extent practicable. Where feasible, design drainage and project plans to complement and utilize existing drainage patterns and systems, conveying drainage from the developed area of the site in a non - erosive manner. Disturbed or degraded natural drainage systems should be restored, where feasible. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -61 4.3.2 -13. Site development on the most suitable portion of the site and design to ensure the protection and preservation of natural and sensitive site resources by providing for the following: A. Protecting areas that provide important water quality benefits, areas necessary to maintain riparian and aquatic biota and /or that are susceptible to erosion and sediment loss; B. Analyzing the natural resources and hazardous constraints of planning areas and individual development sites to determine locations most suitable for development; C. Preserving and protecting riparian corridors, wetlands, and buffer zones; D. Minimizing disturbance of natural areas, including vegetation, significant trees, native vegetation, and root structures; E. Ensuring adequate setbacks from creeks, wetlands, and other environmentally sensitive habitat areas; F. Promoting clustering of development on the most suitable portions of a site by taking into account geologic constraints, sensitive resources, and natural drainage features G. Utilizing design features that meet water quality goals established in site design policies. 4.3.2 -14. Whenever possible, divert runoff through planted areas or sumps that recharge the groundwater dry wells and use the natural filtration properties of the earth to prevent the transport of harmful materials directly into recreational waters. 4.3.2 -15. Where infiltration of runoff would exacerbate geologic hazards, include equivalent BMPs that do not require infiltration. 4.3.2 -16. Require structural BMPs to be inspected, cleaned, and repaired as necessary to ensure proper functioning for the life of the development. Condition coastal development permits to require ongoing application and maintenance as is necessary for effective operation of all BMPs (including site design, source control, and treatment control). CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -62 4.3.2 -17. Utilize permeable surfaces that permit the percolation of urban runoff in non - sidewalk areas within the City's parkway areas, to the maximum extent practicable. 4.3.2 -18. Condition coastal development permits to require the City, property owners, or homeowners associations, as applicable, to sweep permitted parking lots and public and private streets frequently to remove debris and contaminated residue. 4.3.2 -19. Require parking lots and vehicle traffic areas to incorporate BMPs designed to prevent or minimize runoff of oils and grease, car battery acid, coolant, gasoline, sediments, trash, and other pollutants to receiving waters. 4.3.2 -20. Require commercial development to incorporate BMPs designed to prevent or minimize the runoff of pollutants from structures, landscaping, parking areas, loading and unloading dock areas, repair and maintenance bays, and vehicle/equipment wash areas. 4.3.2 -21. Require service stations, car washes and vehicle repair facilities to incorporate BMPs designed to prevent or minimize runoff of oil and grease, solvents, car battery acid, coolant, gasoline, and other pollutants to stormwater system from areas including fueling areas, repair and maintenance bays, vehicle/equipment wash areas, and load inglunloading dock areas. 4.3.2 -22. Require beachfront and waterfront development to incorporate BMPs designed to prevent or minimize polluted runoff to beach and coastal waters. 4.3.2 -23. Require new development applications to include a Water Quality Management Plan (WQMP). The WQMP's purpose is to minimize to the maximum extent practicable dry weather runoff and runoff from small storms (less than 314" of rain falling over a 24 -hour period) during construction and post - construction from the property. 4.3.2 -24. To further reduce runoff, direct and encourage water conservation via the use of weather- and moisture -based irrigation controls, tiered water consumption rates, and native or drought - tolerant plantings in residential, commercial, and municipal properties to the maximum extent practicable. 4.3.2 -25. Effectively communicate water quality education to residents and businesses, including the development of a water quality testing lab CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -63 and educational exhibits at the Back Bay Science Center on Shellmaker Island. 4.3.3 Sanitary Sewer Overflows The City of Newport Beach owns and operates a wastewater collection system that collects residential and commercial wastewater and transports it, using a system of 20 pump stations, for treatment by the Orange County Sanitation District. Residences and businesses -- when permitted by the City -- hook up private lateral lines to the City's collection lines. Private and public lines and the City's pump stations have the potential to cause sanitary sewer overflows (SSOs). SSOs lead to several beach closures in and around Newport Beach each year. State law (AB 411, Wayne) requires local health officials to close receiving waters to recreational uses when health officials know of or suspect that an SSO could reach recreational waters. As such, SSOs in Newport Beach and in inland cities can cause closures to Newport Beach's waters. Most SSOs in the area are caused by line blockages. The primary causes of line blockages are grease and root clogs. Newport Beach has adopted regulations for the disposal of grease and other insoluble waste discharges from commercial food preparation facilities to prevent blockages of the sewer system and is investigating alternative grease control methods. As a part of the City's Sewer System Management Plan (SSMP), the City's Utilities Department follows a defined Sewer Master Plan to replace or reline older wastewater lines. Newport Beach also uses remote cameras in sewer lines to look for pipe cracks, root intrusion, and grease buildup to assist in prioritizing the line replacement program. Maintenance failures of plumbing associated with pump stations are another leading cause of SSOs. Newport Beach's Sewer Master Plan includes upgrades of its pump stations, including replacing pump stations with gravity systems where possible. Upgraded pump stations also include spill- warning systems with multiple communication methods (radio, telephone, pager, and direct line to the City's Utilities yard) to inform Utilities staff of any malfunction. Public education plays an important role in preventing and controlling SSOs. Through water billing and other means, the City reminds the public -- and especially restaurants -- to clean sewer laterals often, maintain private grease control systems, keep roots under control, and to immediately report SSOs. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -64 Policies: 4.3.3 -1. Continue to implement the Sewer System Management Plan and the Sewer Master Plan. 4.3.3 -2. Conduct additional public education reminding property owners and food prepartion facilities to clean sewer laterals often, maintain private grease control systems, keep roots under control, and to immediately report SSOs. 4.3.3 -3. Require waste discharge permits with all food preparation facilities that produce grease and require such permits to include: • Agreements to follow appropriate BMPs; • Maximum grease intrusion levels; • Maintenance /posting of appropriate educational material; • Maintenance log for laterals (at least quarterly); • Maintenance of a log for any grease control device or vat; • Funding for regular compliance inspections; • Acknowledgement of City's ability to fine for non - compliance. 4.3.3 -4. Monitor food preparation facilities via waste discharge permits and monitor spill reduction progress. 4.3.3 -5. Participate with other sewer collection and treatment agencies to investigate alternatives to grease interceptors. 4.3.3 -6. Continue to renovate all older sewer pump stations and install new plumbing according to most recent standards. 4.3.3 -7. Comply with the Regional Board's Waste Discharge Requirements (WDRs) associated with the operation and maintenance of a sewage collection system. Main Channel CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -65 4.4 Scenic and Visual Resources Coastal Act policies related to scenic and visual resources that are relevant to Newport Beach include the following: 30251. The scenic and visual qualities of coastal areas shall be considered and protected as a resource of public importance. Permitted development shall be sited and dagned to protect dews to and along the ocean and scenic coastal areas, to minimize the alteration of natural land farms, to be visually compatible with the character of surrounding areas, and, where feasible, to restore and enhance visual quality in visually degraded areas. New development in tigliy scenic areas such as those designated in the California Coastline Preservation and Recreation Plan prepared by the Department of Parks and Recreation and by local govemmert shall be subordinate to the character of its setting. 4.4.1 Coastal Views Newport Beach is located in a unique physical setting that provides a variety of spectacular coastal views, including those of the open waters of the ocean and bay, sandy beaches, rocky shores, wetlands, canyons, and coastal bluffs. The City has historically been sensitive to the need to protect and provide access to these scenic and visual resources and has developed a system of public parks, piers, trails, and viewing areas. Coastal views are also provided from a number of streets and highways and, due to the grid street pattern in West Newport, Balboa Peninsula, Balboa Island, and Corona del Mar, many north -south tending streets provide view corridors to the ocean and bay. Little Corona CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -66 Policies: 4.4.1 -1. Protect and, where feasible, enhance the scenic and visual qualities of the coastal zone, including public views to and along the ocean, bay, and harbor and to coastal bluffs and other scenic coastal areas. 4.4.1 -2. Design and site new development, including landscaping, so as to minimize impacts to public coastal views. 4.4.1 -3. Where appropriate, require new development to provide view easements or corridors designed to protect public coastal views or to restore public coastal views in developed areas. Ocearhau Boardwalk at 25` Street Beach 4.4.1 -4. Where feasible, require new development to restore and enhance the visual quality in visually degraded areas. 4.4.1 -5. Protect public coastal views from the following roadway segments: • Backbay Drive. • Balboa Island Bridge. • Bayside Drive from Coast Highway to Linda Island Drive. • Bayside Drive at Promontory Bay. • Coast Highway /Santa Ana River Bridge. • Coast Highway /Newport Boulevard Bridge and Interchange. • Coast Highway from Newport Boulevard to Marino Drive. • Coast Highway /Newport Bay Bridge. • Coast Highway from Jamboree Road to Bayside Drive. • Eastbluff Drive from Jamboree Road to Backbay Drive. • Irvine Avenue from Santiago Drive to University Drive. • Jamboree Road from Eastbluff Drive /University Drive to State Route 73. • Jamboree Road in the vicinity of the Big Canyon Park. • Jamboree Road from Coast Highway to Bayside Drive. • Lido Island Bridge. • Newport Boulevard from Hospital Road/Westwinster Avenue to Via Lido Drive. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -67 • Newport Center Drive from Newport Center Drive E/W to Farallon Drive /Granville Drive. • Ocean Boulevard. • State Route 73 from Bayview Way to University Drive. • Superior Avenue from Hospital Road to Coast Highway. • University Drive from Irvine Avenue to the Santa Ana — Delhi Channel. 4.4.1 -6. Design and site new development, including landscaping, on the edges of public coastal view corridors, including those down public streets, to frame and accent public coastal views. 4.4.1 -7. Design and maintain parkway and median landscape improvements in public rights -of -way so as not to block public coastal views at maturity. 4.4.1 -8. Where feasible, provide public trails, recreation areas, and viewing areas adjacent to public coastal view corridors. 4.4.1 -9. Restrict development on sandy beach areas to those structures directly supportive of visitor - serving and recreational uses, such as lifeguard towers, recreational equipment, restrooms, and showers. Design and site such structures to minimize impacts to public coastal views. 4.4.2 Bulk and Height Limitation Concern over the intensity of development around Lower Newport Bay led to the adoption of a series of ordinances in the early 1970s that established more restrictive height and bulk development standards around the bay. The intent was to regulate the visual and physical mass of structures consistent with the unique character and visual scale of Newport Beach. As a result, new development within the Shoreline Height Limitation Homes on the Balboa Pennsula Zone is limited to a height of 35 feet. Residential development is limited to a height of 24 to 28 feet and non - residential development is limited to a CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -68 height of 26 to 35 feet. Outside of the Shoreline Height Limitation Zone, heights up to 50 feet are permitted within the planned community districts. There are also two properties in the coastal zone that are within the High Rise Height Limitation Zone, which are permitted heights up to 375 feet. The first is the site of Newport Beach Marriott Hotel in Newport Center; the other is an undeveloped office site northeast of the Jamboree Road /State Route 73 interchange. Floor areas are strictly limited citywide. In the coastal zone, residential development is limited to floor areas ranging from 1.5 to 2.0 times the buildable area of the parcel (the land minus required setback yards), which typically translates to actual floor area ratios of 0.95 to 1.35. Nonresidential development floor area ratios range from 0.30 to 1.25. Policies: 4.4.2 -1. Maintain the 35 -foot height limitation in the Shoreline Height Limitation Zone. 4.4.2 -2. Continue to regulate the visual and physical mass of structures consistent with the unique character and visual scale of Newport Beach. 4.4.3 Coastal Bluffs Coastal bluffs are a prominent landform in Newport Beach. There are ocean facing coastal bluffs along the shoreline of Corona del Mar, Shorecliffs, and Cameo Shores. There are also coastal bluffs facing the wetlands of Upper Newport Bay, Semeniuk Slough, and the degraded wetlands of the Banning Ranch property. Finally, there are coastal bluffs surrounding Lower Newport Bay. These can be seen along Coast Highway from the Semeniuk Upper Newport Bay coastal duffs Slough to Dover Drive and in Corona del Mar above the Harbor Entrance. These bluffs faced the open ocean before the Balboa Peninsula formed and are now generally separated from the shoreline. Coastal bluffs are considered significant scenic and environmental resources and are to be protected. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -69 Most of the coastal bluff top lands have been subdivided and developed over the years. However, many have been preserved as parkland and other open space. Also, most of the faces of the coastal bluff surrounding the Upper Newport Bay have been protected by dedication to the Upper Newport Bay Nature Preserve or dedicated as open space as part of planned residential developments. In other areas, including Newport Heights, Cliff Haven, Irvine Terrace, Corona del Mar, Shorecliffs, and Cameo Shores, the coastal bluffs fall within conventional residential subdivisions. Development on these lots occurs mainly on a lot -by -lot basis. As a result, some coastal bluffs remain pristine and others are physically or visually obliterated by structures, Iandform alteration or landscaping. Policies regarding coastal bluffs need to make a distinction between areas where the coastal bluff is essentially unaltered and those in developed areas where the coastal bluff has been altered. In areas with unaltered coastal bluffs, development on the bluff face should be prohibited, with exceptions for certain public improvements, and development of bluff top should be controlled. In areas where the coastal bluff has been altered, development on the bluff face and bluff top should be controlled to minimize further alteration. The bluffs along Bayside Drive were at one time exposed to the Lower Newport Bay. However, these bluffs separated from the shoreline when abutting tidelands were filled and reclaimed in the 1920s and later developed into the communities of Promontory Bay, Beacon Bay, and Bayside. Later development of Irvine Terrace and Promontory Point cut and filled these bluffs to an extent that they can be best identified as manufactured slopes rather than natural slopes. Given that the bluffs along Bayside Drive have faces that are not the result of erosion, faulting, or folding and are no longer subject to marine erosion, they did not meet the definition of coastal bluffs and are not subject to the policies of this section. Geomorphic map of Newport Beach CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -70 Policies: 4.4.3 -1. In areas where the coastal bluff remains essentially unaltered, require new development to dedicate or preserve as open space the bluff face and an area inland from the edge of the bluff adequate to provide safe public access and to avoid or minimize visual impacts. 4.4.3 -2. In areas where the coastal bluff remains essentially unaltered, require all new development located on a bluff top to be setback from the bluff edge a sufficient distance to ensure that it will not be endangered by erosion and to avoid the need for protective devices during the economic life of the structure (75 years). 4.4.3 -3. In areas where the coastal bluff remains essentially unaltered, prohibit development on bluff faces, except public improvements providing public access, protecting coastal resources, or providing for public safety. Permit such improvements only when no feasible alternative exists and when designed and constructed to minimize alteration of the bluff face, to not contribute to further erosion of the bluff face, and to be visually compatible with the surrounding area to the maximum extent feasible. 4.4.3 -4. In areas where the coastal bluff has been altered, establish setback lines for principal and accessory structures based on the predominant line of existing development along the bluff in each block. Apply the setback line downward from the edge of the bluff and /or upward from the toe of the bluff to restrict new development from extending beyond the predominant line of existing development. 4.4.3 -5. In areas where the coastal bluff has been altered, design and site development to minimize alteration of those portions of coastal bluffs with slopes in excess of 20 percent (5:1 slope). Prohibit development on those portions of coastal bluffs with unaltered natural slopes in excess of 40 percent (2.5:1 slope), unless the application of this policy would preclude any reasonable economic use of the property. 4.4.3 -6. Coastal bluffs do not include bluffs along Bayside Drive that have been cut and filled by the Irvine Terrace and Promontory Point developments and are no longer subject to marine erosion. 4.4.3 -7. Require applications for new development to include slope stability analyses and erosion rate estimates provided by a licensed Certified Engineering Geologist or Geotechnical Engineer. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -71 4.4.3 -8. Employ site design and construction techniques to minimize alteration of coastal bluffs, such as: A. Siting new development on the flattest area of the site, except when an alternative location is more protective of coastal resources. B. Utilizing existing driveways and building pads to the maximum extent feasible. C. Clustering building sites. D. Shared use of driveways. E. Designing buildings to conform to the natural contours of the site, and arranging driveways and patio areas to be compatible with the slopes and building design. F. Utilizing special foundations, such as stepped, split level, or cantilever designs. G. Detaching parts of the development, such as a garage from a dwelling unit. H. Requiring any altered slopes to blend into the natural contours of the site. 4.4.3 -9. Require new development adjacent to the edge of coastal bluffs to incorporate drainage improvements, irrigation systems, and /or native or drought - tolerant vegetation into the design to minimize coastal bluff recession. 4.4.3 -10. Design and site new development to minimize the removal of native vegetation, preserve rock outcroppings, and protect coastal resources. 4.4.3 -11. Design land divisions, including lot line adjustments, to minimize impacts to coastal bluffs. 4.4.3 -12. Identify and remove all unauthorized structures, including protective devices, fences, and stairways, which encroach into coastal bluffs. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -72 4.4.4 Signs and Utilities The City has adopted special sign regulations for the Mariner's Mile commercial district and for the Balboa Peninsula. These sign regulations include limitations on freestanding and roof signs, which have the greatest potential to impact coastal scenic and visual resources. In some of the older neighborhoods, electrical, telephone, cable television, and other utility lines are still located above ground. The City requires Overhead udliues were placed rodeo nd h Balboa Wage utilities to be placed underground in all new developments and has ongoing programs to remove and underground overhead utilities through the establishment of underground utility districts. Policies: 4.4.4 -1 4.4.4 -2. 4.4.4 -3. 4.4.4 -4. 4.4.4 -5. 4.4.4 -6. 4.4.4 -7 Design and site signs, utilities, and antennas to minimize visual impacts to coastal resources. Continue to implement the special sign regulations in Mariner's Mile and on the Balboa Peninsula. Update sign regulations for the West Newport, Marine Avenue, and Corona del Mar commercial areas. Implement programs to remove illegal signs and amortize legal nonconforming signs. Continue to strictly limit billboards and other off -site signs. Continue to require new development to underground utilities. Continue programs to remove and underground overhead utilities. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -73 4.5 Paleontological Cultural Resources Coastal Act policies related to paleontological, archaeological, and historical Resources that are relevant to Newport Beach Include the following: 30244. where development waWd adversely impact anhaeoloocal or paleontological resources as ider0ed by the State Historic Preservation Officer, reasonable mitigation measures shall be regL*W. 4.5.1 Paleontological and Archaeological Resources Orange County's geologic history began 175 - 145 million years ago, in the Middle to Late Jurassic Period. The oldest rocks in Orange County are located in the central Santa Ana Mountains and contain fossils such as radiolarians, ammonites and bivalves. These types of rocks and fossils indicate that this area was under the ocean. Therefore, for most of its geologic history, Orange County was underwater. During the Miocene Epoch (26 — 7 million years ago) tectonic forces produced mountain uplifts, initiated movement on the nascent San Andreas fault system, and formed numerous coastal marine basins, including the Los Angeles Basin, of which most of Orange County is a part. Orange County became a shallow bay as the sea retreated. Miocene fossils are from both marine and land organisms, as the area was a shallow sea surrounded by jungles and savannas. Tectonic forces began to uplift the land during the Pliocene (7 - 2.5 million years ago). The sea began to slowly recede from the coast. Each successive shoreline is represented today by a marine terrace and can be seen in Corona del Mar today. Three marine terraces can be seen north of Corona del Mar by driving toward the beach on MacArthur Boulevard. Sandstone deposited in the Newport Beach area in the late Pliocene contains a wealth of marine mammals, sea birds and a variety of seashells. The seas continued to regress during the cooler Pleistocene (2.5 million — 15,000 years ago), and tectonic forces continued to uplift the land. Although the Pleistocene Epoch is called the "Ice Age," glacial ice never reached Southern California. A heavily vegetated, marshy area extended inland beyond the shoreline, and a great variety of vertebrate Ice Age animals lived in the area. Fossils of Ice Age horses, elephants, bison, antelopes and Dire wolves have been found at sites near the Castaways. The first generally accepted period of human occupation of the Southern California began around the end of the Pleistocene, about 10,000 to 12,000 years ago. Some of the evidence of the earliest human occupation in Orange County was found at archaeological sites around the Upper Newport Bay. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -74 Tongva steatite bovA recovered from a development site Policies: These and other archaeological sites in Newport Beach present evidence that highly mobile and resourceful people lived here as far back as 9,500 years ago. A village site excavated in Newporter North was occupied at various times over 5,500 years. Archaeological excavations indicate that the earliest people followed the seasonal migration of animals and collected a wide variety of wild plant resources. Later inhabitants were more sedentary, hunting sea mammals, small and large terrestrial mammals, fish, bird, and shellfish. 4.5.1 -1. Require new development to protect and preserve paleontological and archaeological resources from destruction, and avoid and minimize impacts to such resources. If avoidance of the resource is not feasible, require an in situ or site - capping preservation plan or a recovery plan for mitigating the effect of the development. 4.5.1 -2. Require a qualified paleontologist/archeologist to monitor all grading and /or excavation where there is a potential to affect cultural or paleontological resources. If grading operations or excavations uncover paleontologicaVarchaeological resources, require the paleontologist/archeologist monitor to suspend all development activity to avoid destruction of resources until a determination can be made as to the significance of the paleontological / archaeological resources. If found to be significant, require the site(s) to be preserved for a reasonable period of time to allow a recovery plan to be completed to assure the protection of the paleontological /archeological resources. 4.5.1 -3. Notify cultural organizations, including Native American organizations, of proposed developments that have the potential to adversely impact cultural resources. Allow qualified representatives of such groups to monitor grading and /or excavation of development sites. 4.5.1 -4. Require new development to donate scientifically valuable paleontological or archaeological materials to a responsible public or CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -75 private institution with a suitable repository, located within Orange County, whenever possible. 4.5.1 -5. Continue to protect Upper Newport Bay cliff faces to serve as a reference section for micropaleontological studies. Plaque commemorating first water-to-water Bight 4.5.2 Historical Resources Newport Beach has a number of buildings and sites in the coastal zone that are representative of the history of the community and the region. Some of these historical resources have been recognized as being of statewide or national importance. There are four properties in Newport Beach that are listed as California Historical Landmarks: • Old Landing (No. 198). Established by Captain Dunnells in the 1870's, it was the site of the first shipping business in Newport Bay. • Site Of First Water -To -Water Flight (No. 775). Commemorates the May 10, 1912 flight of Glenn L. Martin from the waters of the Pacific Ocean at Balboa to Catalina Island, the first water -to -water flight. • McFadden Wharf (No. 794). The site of the original wharf built in 1888 by the McFadden brothers. • Balboa Pavilion (No. 959). Built in 1905, it is one of California's last surviving examples of the great waterfront recreational pavilions from the turn of the century. CITY COUNCIL DRAFT 1 Local Coastal Program Coastal Land Use Plan 4 -76 There are also three properties that are listed in the National Register of Historic Places: • Balboa Inn. Built in 1929, the Balboa Inn is representative of Spanish Colonial Revival architecture and beachfront tourist development. Early photograph of the Balboa Pavilion • Balboa Pavilion. Built in 1905, the Balboa Pavilion is one of California's last surviving examples of the great waterfront recreational pavilions from the turn of the century. • Lovell Beach House. Built in 1926, the Lovell Beach House was designed by Rudolf Schindler and is considered the first pure International Style house built in America. The City of Newport Beach has also listed seven properties in the Newport Beach Register of Historical Property in recognition of their local historical or architectural significance. In addition to the Balboa Pavilion and the Balboa Inn, the Newport Beach Register of Historical Property includes: • Rendezvous Ballroom Site. Destroyed by fire in 1966, the Rendezvous Ballroom was a popular Balboa dance hall that featured numerous famous Big Bands of the 1930's and 1940's. • Pepper's Restaurant. The exposed structural components of Pepper's Restaurant are timbers used in the original Balboa Island Bridge and McFadden Wharf. • Balboa Theater. Built in 1928, the Balboa Theater is a former vaudeville theater that one time housed an infamous speakeasy during Prohibition. • Balboa Saloon. The 1924 building is representative of Newport's nautical history and Main Street commercial masonry style.
