This item was continued from the April 28, 2020, City Council meeting. RECOMMENDATION: a) Conduct a de novo public hearing; b) Find this project exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15332 under Class 32 (In -Fill Development Projects) of the CEQA Guidelines, because it has no potential to have a significant effect on the environment; and, c) Adopt Resolution No. 2020-33: A Resolution of the City Council of the City of Newport Beach, California, Upholding and Affirming the Planning Commission's Approval of Coastal Development Permit No. CD2019-003 and Conditional Use Permit No. UP2019-003 to Demolish an Existing Restaurant and Office Building and Construct a New Office Building and Parking Structure Located at 215 Riverside Avenue (PA2019- 023); or d) Direct staff to return with a Resolution Reversing or Modifying the Planning Commission's Approval of Coastal Development Permit No. CD2019-003 and Conditional Use Permit No. UP2019-003 to Demolish an Existing Restaurant and Office Building and Construct a New Office Building and Parking Structure Located at 215 Riverside Avenue (PA2019-023). 21-1 Resolution 2020-33: Appeal of Planning Commission Approval for The Garden Office and Parking Structure Proposed at 215 Riverside Avenue (PA2019-023) May 12, 2020 Page 2 FUNDING REQUIREMENTS: There is no fiscal impact related to this item. DISCUSSION: City Council Consideration The application request and details of the appeal are summarized in the April 14, 2020, City Council packet, included herein as Attachment B. The appeal letter is provided as Attachment C. Public comments from this City Council packet and prior meetings are included as Attachments D and E. The City Council held a televised, web -based, telephonic public hearing on April 28, 2020. Following the staff and the applicant presentations and midway through the appellants' presentation, the City Council voted to continue the item due to technical difficulties. The staff report and public comments from this meeting are provided as Attachments F and G. The current project plans provided by the applicant are included as Attachment H. At the April 28, 2020 meeting, the applicant agreed to additional and/or revised conditions of approval for the project in order to address concerns raised by the appellants. For City Council's consideration to include in the attached resolution are the following proposed revised conditions: 61. Prior to the issuance of building permits, the Project plans shall be modified to extend the proposed trellis at the upper deck of the parking structure across the 8Rtire both rowsof parkiRg spaG8c aIGRg the southerly ren o�aGiRg AVeR Street. The trellis will be completely foliated with vines and other organic material to provide a green, landscape covering to help reduce noise and light spillage. 62. Exterior lighting shall be limited to the minimum necessary for site security after 11 00; 10:15 p.m., seven (7) days a week, on the upper deck of the parking structure. 63. Vehicles shall not be allowed to enter the upper level of the parking structure from 11,-r 00 p.m -10:00 p.m. through 6:00 a.m., seven (7) da ss4y a week. 65. Prior to the issuance of demolition and grading permits, the City's Arborist will review the Project plans for conformity with applicable City regulations. 66. Prior to the issuance of grading permits, the Project Applicant or Project Developer will retain a licensed arborist to observe construction of the prosect to ensure compliance with Council Policv G-1 (Retention. Removal and Maintenance of Citv Trees) related to Special Trees and the City Arborist's findings. 21-2 Resolution 2020-33: Appeal of Planning Commission Approval for The Garden Office and Parking Structure Proposed at 215 Riverside Avenue (PA2019-023) May 12, 2020 Page 3 The appellant has also requested the following additional conditions of approval, which the applicant was either not willing to agree to or their posiiton is unknown because of the abrupt end to the meeting: 1. Installation of a roof or complete covering over the second level of the parking structure. Alternatively, a trellis cover over the entire upper deck of the parking structure (including drive aisles). 2. Vehicles shall not be allowed to enter or leave the lower level of the parking structure from 10 p.m. through 6 a.m., seven (7) days a week. 3. Motorcycles should be prohibited from utilizing the parking structure. 4. The North and West walls of the parking structure shall be built with solid material, such as concrete or concrete block with no openings or voids toward the upper residences or the park. 5. Vehicles shall only be parked in designated parking spaces. A valet plan that includes vehicles stacked in tandem configurations shall be prohibited. Limit the number of cars that utilize the parking structure to those striped in the lot. 6. The parking structure shall only be used for parking cars and no other uses or gatherings shall be allowed. The applicant has expressed concern that the structural design of the parking structure would have to be radically modified to accommodate the roof request. The applicant has previously agreed to a trellis covering over both rows of parking completely foliated with vines as identified in Condition No. 61, above. This additional trellis results in the loss of one parking space to accommodate the trellis supports. The City does not have any specific development standards that require a roof or other covering on the parking structure. However, the conditional use permit process is designed to allow the hearing body the discretion to make sure any potential negative effects between land uses are adequately addressed. Secondly, the applicant does not believe that the appellants' request to extend use limitations to the lower level have a direct connection to minimize potential land use conflicts with the adjacent residences. Staff believes that the prohibition of certain vehicle types (motorcycles) would be difficult to enforce. Solid parking structure walls at the north and west would help reduce noise and fumes oriented toward the adjacent residents and the parking structure would need to continue to comply with venting requirements per the building code. 21-3 Resolution 2020-33: Appeal of Planning Commission Approval for The Garden Office and Parking Structure Proposed at 215 Riverside Avenue (PA2019-023) May 12, 2020 Page 4 Analysis The appellants and public comments raised several concerns at the public hearing on April 28, 2020, which are referenced below with staff's analysis: Coast Live Oak Tree Several comments were submitted prior to the public hearing indicating that the roots of an oak tree located to the north of the Project would be damaged by project construction. The oak tree is located on private property at 2911 Cliff Drive, north of an existing retaining wall near the driveway entrance onto Riverside Avenue. Since this is a private tree, it is not subject to Council Policy G-1 (Retention, Removal, and Maintenance of City Trees). City trees in the figure above are identified with a purple dot. Thus, Condition Nos. 65 and 66 as proposed by the applicant and agreed upon by the appellant are not applicable to this project. Staff recommends the following alternative language to ensure the protection of this private tree: 65. Prior to the issuance of grading permits, the landscape plan shall be updated to reflect that the existing oak tree north of the subject property at 2911 Cliff Drive shall be protected in place. The applicant shall submit a report prepared by a Consulting Arborist (American Society of Consulting Arborists) that includes recommendations regarding potential impacts to the existing oak tree located at 2911 Cliff Drive during demolition and grading. The report may include an initial analysis and recommendations regarding demolition and construction practices, including but not limited to procedures for observation and site monitoring during demolition and grading. The report shall be reviewed by the City's arborist prior to issuance of grading permits. The contractor shall follow the Arborist's recommendations throughout project construction. 21-4 Resolution 2020-33: Appeal of Planning Commission Approval for The Garden Office and Parking Structure Proposed at 215 Riverside Avenue (PA2019-023) May 12, 2020 Page 5 General Plan, Local Coastal Program, and California Coastal Act Consistency: David Tanner's April 27, 2020, public correspondence (Attachment G, Page 8) indicates that several applicable policies were omitted from the analysis. The General Plan and Coastal Land Use Plan policy analysis provided in the Planning Commission staff report and Class 32 exemption narrative are designed to focus on the most relevant policies for discussion purposes. Ultimately, the Zoning Code is intended to serve as the implementing document for the General Plan (GP) and the Local Coastal Program is intended to serve as the implementing document for the Coastal Land Use Plan. The following analysis addresses the additional policies identified in David Tanner's correspondence dated April 27, 2020, and identifies which standards of the Zoning Code and Local Coastal Program implement these policies: • Policy LU1.3: Natural Resources, "Protect the natural setting that contributes to the character and identity of Newport Beach and the sense of place it provides for its residents and visitors. Preserve open space resources, beaches, harbor, parks, bluffs, preserves, and estruaries as visual, recreational, and habitat resources." A major component of implementation of this policy is through the Open Space (OS) and Parks and Recreation (PR) zoning districts which contain development standards and use regulations to protect these resources. Additionally, this policy is implemented through Zoning land use limitations, setbacks, height limits (Section 20.30.060), bluff overlay development standards (Section 20.28.040), environmental review procedures (Section 20.50.080), and Council Policy K-3 (Implementation Procedures for CEQA). • Policy LU3.7: Natural Resource or Hazard Areas, "Require that new development is located and designed to protect areas with high natural resource value and protect residents and visitors from threats to life or property." This GP policy is implmented through setbacks, bluff overlay development standards (Section 20.28.040), environmental review procedures (Section 20.50.080), and Council Policy K-3 (Implementation Procedures for CEQA). • Policy NR10.4: New Development Siting and Design, "Require that siting and design of new development, including landscaping and public access, protect sensitive or rare resources against any significant disruption of habitat values." This GP policy is implmented through Zoning development standards for setbacks, bayfront public access standards (Section 20.30.090), landscaping standards (Chater 20.36), environmental review procedures (Section 20.50.080), and Council Policy K-3 (Implementation Procedures for CEQA). The proposed project complies with all applicable development standards and a biological analysis determined the project would not impact the nearby wetland. 21-5 Resolution 2020-33: Appeal of Planning Commission Approval for The Garden Office and Parking Structure Proposed at 215 Riverside Avenue (PA2019-023) May 12, 2020 Page 6 • Policy NR10.6: Use of Buffers, "Maintain a buffer of sufficient size around significant or rare biolgical resources, if present, to ensure the protection of these resources. Require the use of native vegetation and prohibit invasive plant species within these buffer areas." This GP policy is implmented through Zoning setbacks, landscaping standards (Chater 20.36), environmental review procedures (Section 20.50.080), and Council Policy K-3 (Implementation Procedures for CEQA). The proposed project has been designed and reviewed to comply with these standards. • Policy LU5.1.2, Compatible Interfaces, "Require that height of development in nonresidential and higher -density residential areas transition as it nears lower - density residential areas to minimize conflicts at the interface between the different types of development." This GP policy is implemented through Section 20.30.060 (Height Limits and Exceptions) of the Zoning Code. The conditional use permit process further provides the decision-making body with the discretion to apply more restrictive conditions (such as reduced height), where appropriate. • Policy CE7.1.8, Parking Configuration, "Site and design new development to avoid the use of parking configurations or management programs that are difficult to maintain and enforce." This GP policy is implemented through Chapter 20.40 (Off -Street Parking Standards). The conditional use permit process further provides the decision-making body with the discretion to apply more restrictive conditions, where appropriate. The proposed project has been reviewed by the City's traffic engineer and the parking lot design complies with applicable standards and policies. • Section 30240 of the California Coastal Act: Environmentally sensitive habitat areas; adjacent developments, "(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 shall be sited and designed to prevent impacts which would significantly degrade those areas, and shall be compatible with the continuance of those habitat and recreation areas." This Coastal Act Section is implemented through Local Coastal Program Sections 21.306 (Habitat Protection), 21.30A.050 (Development Standards), the required findings for a Coastal Development Permit (Section 21.52.0155), and Council Policy K-3 (Implementation Procedures for CEQA). 21-6 Resolution 2020-33: Appeal of Planning Commission Approval for The Garden Office and Parking Structure Proposed at 215 Riverside Avenue (PA2019-023) May 12, 2020 Page 7 The proposed project complies with all development standards of the Zoning Code and Local Coastal Program and thus implements the policies described above. The design utilizes the existing development footprint and retaining wall on-site and does not increase the area of disturbance. Further, the property is not subject to bluff overlay development standards and the project increases the buffer from the nearby wetland along Avon Street. The private tree on the adjacent property is a civil matter and will be protected in place. Proposed development will not extend any closer to this tree than the existing retaining wall. This type of project, code -compliant parking strucure, requires a CUP because it is adjacent to residential uses. The CUP process allows for a more detailed review and requires that findings be made to approve the project. This process provides the hearing body (City Council or Planning Commission) with the authority to require additional improvements or design changes through conditions of approval. ENVIRONMENTAL REVIEW: The project is categorically exempt under Section 15332, of the California Environmental Quality Act (CEQA) Guidelines - Class 32 (In -Fill Development Projects). This exemption applies to in -fill development projects in urban areas that are consistent with the General Plan and applicable development standards. In addition, the proposed development must occur on a site of no more than five acres, have no value as habitat for endangered, rare or threatened species, be adequately served by all utilities and public services, and must not result in any significant effects relating to traffic, air quality, water quality, or any other significant effect on the environment due to an unusual circumstance. The proposed project site is 0.37 acres in size, is located within an urban area, and can be adequately served by all required utilities and public services. The project is consistent with the General Plan and Local Coastal Program designations and policies and can be found consistent with all applicable Zoning regulations upon approval of the requested CUP. A noise study, preliminary water quality management plan (WQMP), traffic analysis, water/waste-water generation memorandum, biological resources analysis and geotechnical investigation and analysis have been prepared. A further biological analysis indicates that the adjacent (off-site) wetland and riparian habitat not be negatively impacted by the proposed project and that the proposed wetland buffer is appropriate. The project is expected to have less than significant impacts related to traffic, noise, air quality, and water quality as demonstrated by these studies. A more detailed analysis supporting a Class 32 exemption determination including supporting documentation is attached as the draft resolution for project approval (Attachment A). 21-7 Resolution 2020-33: Appeal of Planning Commission Approval for The Garden Office and Parking Structure Proposed at 215 Riverside Avenue (PA2019-023) May 12, 2020 Page 8 NOTICING: This item was continued to a date certain from the April 28, 2020, City Council Meeting.

NOW, THEREFORE, the City Council of the City of Newport Beach resolves as follows: Section 1: The City Council does hereby find the Project is categorically exempt from the California Environmental Quality Act ("CEQA") pursuant to Section 15332 under Class 32 (Infill Development Projects) of the CEQA Guidelines, California Code of Regulations, Title 14, Division 6, Chapter 3, because the Project consists of an in -fill development project. The additional facts in support of the CEQA determination are set forth in Exhibit "A" which is incorporated herein by reference. Section 2: The City Council does hereby uphold the Planning Commission's approval of Coastal Development Permit No. CD2019-003 and Conditional Use Permit No. UP2019-003, subject to the conditions of approval attached as Exhibit "B" and incorporated herein by reference. The City Council's decision is made in accordance with Sections 21.52.015(F) (Coastal Development Permits, Findings and Decision) and Section 20.52.020(F) (Conditional Use Permits and Minor Use Permits, Findings and Decision) of the NBMC, and is supported by the following findings and facts: I. COASTAL DEVELOPMENT PERMIT A coastal development permit is required to authorize the demolition and redevelopment on the Property. In accordance with Section 21.52.015(F) (Coastal Development Permits, Findings and Decision) of the NBMC, the following findings and facts in support of such findings are set forth: Finding: A. Conforms to all applicable sections of the certified Local Coastal Program. Facts in Support of Finding: 1. The Project complies with applicable development standards including, but not limited to, floor area limitation, setbacks, height, and parking. 21-12 Resolution No. 2020-33 Page 4 of 10 a. The maximum floor area limitation is equal to a floor area ratio ("FAR") of 0.5 or 8,145 square feet and the proposed floor area is 0.17 FAR or 2,744 square feet. b. The Project provides the minimum required setbacks, which are zero (0) feet along the front property line abutting Riverside Avenue and Avon Street, zero (0) feet on the right side yard, and five (5) feet on the left side yard and rear yard abutting the residential properties. c. The highest parapet is 28 feet from established grade (30.5 feet North American Vertical Datum of 1988 [NAVD 88]), which complies with the maximum height requirements. d. The Project includes a parking structure for a total of 41 vehicles, complying with the minimum 11 parking spaces required for the 2,744 -square -foot office development on-site 2. The front fagade of the parking structure has been designed to be architecturally compatible with and appear as an extension to the shopping center located to the south across Avon Street. The proposed design, bulk, and scale of the development is consistent with the existing neighborhood pattern of development and expected future development. The bulk of the proposed building is similar to or less than that of the existing development on site. 3. The Property is an inland parcel that is not located on the waterfront. 4. An initial biological resources analysis of the Property indicates that the adjacent Avon Street right-of-way, west of the Property, is characterized by wetland areas located within 100 feet of the Property. The report evaluates the proposed wetland buffer and concludes that a 100 -foot buffer is not necessary and that the proposed 39 -foot wetland buffer is sufficient for protection of the wetland and that the Project will not impact habitat for endangered, rare, or threatened species. 21-13 Resolution No. 2020-33 Page 5 of 10 5. The Property is located in an area known for the potential of seismic activity and liquefaction. All projects are required to comply with the California Building Code ("CBC") and Building Division standards and policies. A geotechnical investigation was prepared, attached hereto as Exhibit C and incorporated herein by this reference, which includes design recommendations to address liquefaction and other geologic issues. A final Geotechnical report and investigation specifically addressing liquefaction and other geologic related design issues is required to be reviewed and approved prior to the issuance of building permits. Permit issuance is also contingent on the inclusion of design mitigation identified in the investigations. Construction plans are reviewed for compliance with approved investigations and CBC prior to building permit issuance. 6. The Property is not located within 200 feet of coastal waters. The Project design addresses water quality with a construction erosion control plan and a post - construction drainage system. The Project is required to adhere to the City's grading, erosion control, and drainage requirements that includes percolation features and retention of dry weather and minor rain event run-off on-site. Any water not retained on-site is directed to the City's storm drain system. 7. Due to the area of proposed impervious surfaces on the Project site, a Water Quality Management Plan ("WQMP") / Water Quality and Hydrology Plan ("WQHP") is required. A WQMP/WQHP prepared by Total Engineering, Inc., dated June 17, 2019, has been reviewed and approved by the City's Engineer Geologist. The WQMP/WQHP includes a polluted runoff and hydrologic site characterization, a sizing standard for Best Management Practices ("BMPs"), use of a Low Impact Development ("LID") approach and bio filtration planters to retain the design storm runoff volume on site, and documentation of the expected effectiveness of the proposed BMPs. 8. Proposed landscaping complies with Section 21.30.075 (Landscaping) of the NBMC. A condition of approval is included that requires drought -tolerant species. Prior to issuance of building permits, the final landscape plans will be reviewed to verify invasive species are not planted. Finding: B. Conforms with the public access and public recreation policies of Chapter 3 of the Coastal Act if the project is located between the nearest public road and the sea or shoreline of any body of water located within the coastal zone. 21-14 Resolution No. 2020-33 Page 6 of 10 Facts in Support of Finding: 1. The Project is not located between the nearest public road and the sea or shoreline; however, the Project is located on a property within 100 feet of a wetland area located within the Avon Street right-of-way. The Project will not affect the public's ability to gain access to, use, and/or view the coast and nearby recreational facilities. 2. Vertical access to the bay front is available approximately 625 feet south of the Property at 2751 West Coast Highway where there is a pedestrian easement with access to the waterfront. 3. Lateral access and views of the bay are also accessible from 2751 West Coast Highway and 2801 West Coast Highway via a six foot wide pedestrian easement. 4. The closest public viewpoint is immediately adjacent and above the Property to the northwest at Cliff Drive Park. The Project is located entirely on private property and will not inhibit coastal views since the Project will be constructed partially into the slope and four feet lower than the 32 foot height limit. View simulations are provided as part of the project plans. Due to the distance and height differential of the Project from these public viewpoints, the development and change of use of the existing building will not impact coastal views. The bulk and scale of the proposed development is similar to that of the existing restaurant and office building with surface parking. The Project is generally not visible from Cliff Drive Park due to the sloping condition of the park, existing vegetation in surrounding areas, and the lower grade of the proposed parking structure and building pad. 5. The closest coastal view road is West Coast Highway, which is located to the south, as designated in the City of Newport Beach Local Coastal Program Coastal Land Use Plan. Views from this vantage point are directed toward the harbor and away from the Property, which is inland and north of West Coast Highway. The bulk and scale of the Project is similar to that of the existing restaurant and office building with surface parking. The proposed office building and accompanying parking structure will complement the architectural style of the adjacent shopping center to the south, improving the character of the community and maintaining a consistent design theme. 21-15 Resolution No. 2020-33 Page 7 of 10 II. CONDITIONAL USE PERMIT Pursuant to Section 20.40.070(B)(3) (Development Standards for Parking Areas, Location of Parking Facilities) of the NBMC, a conditional use permit is required to allow for the construction of a parking structure adjacent to a residential zoning district. In accordance with Section 20.52.020(F) (Conditional Use Permits and Minor Use Permits, Findings and Decision) of the NBMC, the following findings and facts in support of such findings are set forth: Finding: C. The use is consistent with the General Plan and any applicable specific plan. Facts in Support of Finding: 1. The commercial building and related uses are consistent with General Commercial (CG) General Plan land use designation. The parking structure is considered an accessory use that supports the commercial uses. Parking structures are commonly associated with restaurant development and are compatible with the other commercial uses located in Mariners' Mile. 2. The Property is not located within a specific plan area. Finding: D. The use is allowed within the applicable zoning district and complies with all other applicable provisions of this Zoning Code and the Municipal Code. Fact in Support of Finding: 1. The commercial office building and related uses are consistent with the Commercial General (CG) zoning district. The parking structure is considered an accessory use that supports commercial uses. Parking structures located adjacent to residential districts require review and approval of a conditional use permit to minimize impacts to the residential uses. Finding: E. The design, location, size, and operating characteristics of the use are compatible with the allowed uses in the vicinity. 21-16 Resolution No. 2020-33 Page 8of10 Facts in Support of Finding: 1. The parking structure will be visually screened by vegetation surrounding the rear and sides of the parking structure to help block the view from Cliff Drive Park and adjacent residential properties. A portion of the second level structure will be covered by a trellis carport cover adjacent to Avon Street. The trellis adds architectural interest to the architectural fagade of the building and helps to screen portions of the second level parking deck that may be visible to residences above. 2. The parking structure is proposed at the base of the hillside adjacent to a residential district. The neighboring residential properties are located along the top of the hillside approximately 63 feet above the project's first floor pad elevation. The parking structure will be built into an existing retaining wall in the hillside and the second level deck of the parking structure is eight feet above the first floor pad elevation directly adjacent to the residential district. The residential dwellings will remain approximately 55 feet higher in elevation than the surface of the second level parking deck and approximately 48 feet higher in elevation than the top of the parking structure trellis. The closest residential dwelling is located approximately 24 feet from the existing retaining wall supporting the parking structure. These vertical and horizontal separations between the proposed commercial building and the homes provide adequate distance so that the mass and bulk of the parking structure should not negatively impact residents. Finding: F. The site is physically suitable in terms of design, location, shape, size, operating characteristics, and the provision of public and emergency vehicle (e.g., fire and medical) access and public services and utilities. Facts in Support of Finding: 1. The Project results in a parking requirement of 11 spaces, which are provided on- site within the 41 space parking structure. 2. The Traffic Engineer and Fire Department have reviewed the parking lot design and have determined that the parking lot design will function safely and will not prevent emergency vehicle access to the establishment. 21-17 Resolution No. 2020-33 Page 9 of 10 Finding: G. Operation of the use at the location proposed would not be detrimental to the harmonious and orderly growth of the City, or endanger, jeopardize, or otherwise constitute a hazard to the public convenience, health, interest, safety, or general welfare of persons residing or working in the neighborhood of the proposed use. Facts in Support of Finding: 1. Parking structures have the potential to generate noise, such as car alarms, car horns, car audio systems, people talking, vehicle pass -by noise, and engine idling, which have the potential to disturb the adjacent residences. These individual noise sources last for short durations and their occurrences are infrequent; however, they can annoy neighbors. The Project has a 19 space surface level parking lot at approximately the same elevation as the upper level of the proposed parking structure. The proposed parking structure will accommodate more parking spaces at this level (22 spaces) but the impacts from vehicle movements will be similar to that of existing conditions according to the noise analysis as discussed below. 2. A noise analysis was prepared by Urban Crossroads to analyze the potential noise impacts associated with vehicle movements at the uncovered parking structure to the adjacent residents using sound modeling. The analysis concludes that the noise generated from vehicles within the first and second level of the structure will satisfy Section 10.26.025 (Exterior Noise Standards) of the NBMC daytime and nighttime base exterior noise level standards at the nearby noise -sensitive residential homes and adjacent commercial uses. Additionally, a supplemental noise assessment was provided, which compares the projected project noise to the ambient nighttime noise of four commercial parking areas in the City. The results of the supplemental assessment found similar noise levels to the initial analysis and concludes that the initial analysis adequately describes the potential project parking lot noise levels. No additional exterior noise abatement measures are required. 3. The Project has been conditioned to require a photometric study and nighttime light inspection to confirm there light and glare impacts are minimized. Section 3: The recitals provided in this resolution are true and correct and are incorporated into the operative part of this resolution. 21-18 Resolution No. 2020-33 Page 10 of 10 Section 4: If any section, subsection, sentence, clause or phrase of this resolution is, for any reason, held to be invalid or unconstitutional, such decision shall not affect the validity or constitutionality of the remaining portions of this resolution.

Harp City orney Attachments: Exhibit A - California Environmental Quality Act ("CEQA") Determination Exhibit B - Conditions of Approval Exhibit C - Geotechnical Investigation 21-19 EXHIBIT A California Environmental Quality Act ("CEQA") Determination The Garden Office and Parking Structure 215 Riverside Avenue Newport Beach, CA CEQA Section 15332. In -Fill Development Projects The Project is categorically exempt under Section 15332, of the California Environmental Quality Act (CEQA) Class 32 (In -Fill Development Projects) set forth in Title 14, Division 6, Chapter 3 ("CEQA Guidelines"). This exemption applies to in -fill development projects in urban areas that are consistent with the General Plan and applicable development standards. In addition, the proposed development must occur on a site of no more than five (5) acres, have no value as habitat for endangered, rare or threatened species, be adequately served by all utilities and public services, and must not result in any significant effects relating to traffic, air quality, water quality, or any other significant effect on the environment due to an unusual circumstance. Class 32 exemptions for in -fill development projects are required to meet the following conditions: (a) The project is consistent with the applicable general plan designation and all applicable general plan policies as well as with the applicable zoning designation and regulations. The General Plan Land Use Element designates the site as General Commercial (CG) which is intended to provide for a wide variety of commercial activities oriented primarily to serve citywide or regional needs. Development of the site will be consistent with General Plan policies as indicated below. The Project is consistent with the 0.5 FAR limit for the Property. Land Use Policies Policy LU2.1 Resident -Serving Land Uses. Accommodate uses that support the needs of Newport Beach's residents including housing, retail, services, employment, recreation, education, culture, entertainment, civic engagement, and social and spiritual activity that are in balance with community natural resources and open spaces. Policy LU2.2 Sustainable and Complete Community. Emphasize the development of uses that enable Newport Beach to continue as a self-sustaining community and minimize the need for residents to travel outside of the community for retail, goods and services, and employment. Policy LU 2.8 Adequate Infrastructure. Accommodate the types, densities, and mix of land uses that can be adequately supported by transportation and utility infrastructure (water, sewer, storm drainage, energy, and 21-20 so on) and public services (schools, parks, libraries, seniors, youth, police, fire, and so on). Policy LU3.2 Growth and Change. Enhance existing neighborhoods, districts and corridors, allowing for re -use and infill with uses that are complementary in type, form, scale, and character. Changes in use and/or density/intensity should be considered only in those areas that are economically underperforming, are necessary to accommodate Newport Beach's share of projected regional population growth, improve the relationship and reduce commuting distance between home and jobs, or enhance the values that distinguish Newport Beach as a special place to live for its residents. The scale of growth and new development shall be coordinated with the provision of adequate infrastructure and public services, including standards for acceptable traffic level of service. Policy LU 4.1 Land Use Diagram. Accommodate land use development consistent with the Land Use Plan. Figure LU1 depicts the general distribution of uses throughout the City and Figure LU2 through Figure LU15 depict specific use categories for each parcel within defined Statistical Areas. Table LU1 (Land Use Plan Categories) specifies the primary land use categories, types of uses, and, for certain categories, the densities/intensities to be permitted. The permitted densities/intensities or amount of development for land use categories for which this is not included in Table LU1, are specified on the Land Use Plan, Figure LU4 through Figure LU15. These are intended to convey maximum and, in some cases, minimums that may be permitted on any parcel within the designation or as otherwise specified by Table LU2 (Anomaly Locations). The office use is intended to serve local residents and the parking structure will serve the Project while also providing additional spaces to serve surrounding businesses and uses in the Mariners' Mile community on a lease basis. The use complements the existing type and character of the nearby development, which includes a variety of commercial and residential development. As further discussed in part (e) of this analysis, there is adequate capacity in the sewer and water facilities, circulation, and other public services and facilities to provide an adequate level of service to the Project. The Project (i.e., office and parking structure) represents "in -fill" development that can be served by the existing infrastructure. The Property is located within the Commercial General (CG) Zoning District, which is intended to provide for a range of neighborhood -serving retail and service uses along street frontages that are located and designed to foster pedestrian activity. Pursuant to Section 20.20.020 (Commercial Zoning Districts Land Uses and Permit Requirements), office uses are a permitted use within the Commercial General Zoning District. UW 21-21 Project Desiqn Policies Policy 5.2.1 Architecture and Site Design. Require that new development within existing commercial districts and corridors complement existing uses and exhibit a high level of architectural and site design in consideration of the following principals: • Seamless connections and transitions with existing buildings, except where developed as a free-standing building, • modulation of building masses, elevations and rooflines to promote visual interest, • architectural treatment of all building elevations, including ancillary facilities such as storage, truck loading and unloading, and trash enclosures, • treatment of the ground floor of buildings to promote pedestrian activity by avoiding long continuous blank walls, incorporating extensive glazing for transparency, and modulating and articulating elevations to promote visual interest, • clear identification of storefront entries, • incorporation of signage that is integrated with the buildings' architectural character, • architectural treatment of parking structures consistent with commercial buildings, including the incorporation of retail in the ground floors where the parking structure faces a public street or pedestrian way, • extensive on-site landscaping, including mature vegetation to provide a tree canopy to provide shade for customers, • incorporation of plazas and expanded sidewalks to accommodate pedestrian, outdoor dining, and other activities, • clearly delineated pedestrian connections between business areas, parking, and to adjoining neighborhoods and districts (paving treatment, landscape, wayfinding signage, and soon), • integration of building design and site planning elements that reduce the consumption of water, energy, and other renewable resources. The Project includes a 2,744 -square -foot office building and a 41 space parking structure. The building provides a flat parapet roofline and brick fagade with the primary pedestrian entrance located along the street frontage. The architectural style of the building is designed to complement the adjacent retail shopping center to the south, with a brick fagade, fabric awnings, and arched window and entryways. The parking structure is accessible from Avon Street and Riverside Avenue and accommodates visitors, employees, and surplus parking to serve the surrounding area. Appropriate pedestrian connections are maintained along the adjacent sidewalks of Riverside Avenue and Avon Street. A-3 21-22 Neighborhood Compatibility Policies Policy LU5.2.2 Buffering Residential Areas. Require that commercial uses adjoining residential neighborhoods be designed to be compatible and minimize impacts through such techniques as: • Incorporation of landscape, decorative walls, enclosed trash containers, downward focused lighting fixtures, and/or comparable buffering elements; • Attractive architectural treatment of elevations facing the residential neighborhood; • Location of automobile and truck access to prevent impacts on neighborhood traffic and privacy. Policy LU6.16.5 Compatibility of Business Operations with Adjoining Residential Neighborhoods. Work with local businesses to ensure that retail, office, and other uses do not adversely impact adjoining residential neighborhoods. This may include strategies addressing hours of operation, employee loitering, trash pickup, truck delivery hours, customer arrivals and departures, and other activities. Policy LU6.16.6 Design Compatibility with Adjoining Residential Neighborhoods. Require that building elevations facing adjoining residential units be designed to convey a high-quality character and ensure privacy of the residents, and that properties be developed to mitigate to the maximum extend feasible impacts of lighting, noise, odor, trash storage, truck deliveries, and other business related activities. Building elevations shall be architecturally treated and walls, if used as buffers, shall be well-designed and landscaped to reflect the areas residential village character. The Project incorporates a variety of features to ensure neighborhood compatibility, including landscaping at the rear adjacent to residential properties and Cliff Drive Park, attractive architectural treatments including a trellis at the second level of the proposed parking structure. The majority of the parking structure is built into the slope on site to maintain views for surrounding residents and public park areas. Additionally, the Applicant has reduced the height of the parking structure to the height of the existing building. Parking structure access is specifically designed with first level access from Avon Street and second level access from Riverside Avenue to maximize the efficiency of parking and circulation on the Property. The location of vehicle access will ensure existing neighborhood traffic and privacy patterns are maintained. A trash enclosure is located at the southwest portion of the parking structure to minimize odors and noise to the nearby properties. Project lighting will be reviewed with a photometric study at plan check to ensure exterior lighting is compatible with surrounding residential development. Adequate setbacks are incorporated into the Project's design to ensure that the office building and parking structure will be compatible with the adjoining residential properties. A minimum five (5) foot setback is provided between the nearest residences. 21-23 Mariners' Mile Policies LU 6.19.11 Pedestrian -Oriented Village. Require that inland properties that front onto internal streets within the Community/Neighborhood Village locate buildings along and forming a semi continuous building wall along the sidewalk, with parking to the rear in structures or in shared facilities and be designed to promote pedestrian activity. LU 6.19.12 Properties Abutting Bluff Faces. Require that development projects locate and design buildings to maintain the visual quality and maintain the structural integrity of the bluff faces. The Property is located on an inland portion of Mariners' Mile. The proposed office building and parking structure is designed for pedestrian access fronting the intersection of Riverside Avenue and Avon Street to improve the pedestrian oriented quality of the Village area. The site is a steeply sloping lot that was previously developed with a surface level parking area of 18 -parking spaces, and 8,056 -square -foot, three-story, commercial building encompassing office space and a former restaurant. The existing commercial building continues to include office uses and would be demolished. When redeveloped, the new parking structure will make use of an existing retaining wall on the site to maintain the visual quality and integrity of the bluff area at the rear portion of the Property. (b) The proposed development occurs within city limits on a project site of no more than five acres substantially surrounded by urban uses. The Project site is within the Newport Beach city limits, and consists of 16,246 square feet or 0.37 -acres of land area. The Project site is surrounded by other urban uses including retail, restaurant, and office uses to the south and southwest, residential uses to the north and east of the site, and Cliff Drive Park to the northwest and northeast. (c) The project site has no value, as habitat for endangered, rare or threatened species. The Property is vacant and has no native vegetation and/or habitat. As noted above, the site is currently developed with a restaurant and office building with an 18 -space surface parking lot. There is no potential for special -status plants or animals to exist on the vacant lot. A biological resources analysis (Exhibit 5) has confirmed the offsite presence of a wetland resource area, located on the northerly edge of Avon Street to the west of the Property. The memorandum explains that this wetland is a slope wetland or groundwater fed wetland that has been documented at this location since at least 1989. The biological analysis included mapping of the wetland and inventory of the species occupying the area. This indicates the wetland is three (3) to six (6) feet wide directly adjacent to Avon Street and includes a mix of native and non-native species. The source of water is fed by a spring and/or runoff, which drains toward the west, discharging into a drainage culvert west of the Property across from the BMW dealership property. A-5 21-24 Even though the wetland is not on the Project site and no diking dredging or filling is proposed, the following analysis is provided to demonstrate the Project's consistency with the certified Local Coastal Program pursuant to the California Coastal Act. Coastal Land Use Policy 4.2.2.3 and Section 21.306.040 (Wetlands, Deepwater Areas, and Other Water Areas) of the Local Coastal Program requires a 100 foot buffer between development and wetlands unless: a. One hundred (100) foot wide buffer is not possible due to site-specific constraints; and b. The proposed narrower buffer would be amply protective of the biological integrity of the wetland given the site-specific characteristics of the resource and of the type and intensity of disturbance. Existing site wall and driveway encroachments over the Property line would be removed and increase the buffer distance from 29 feet to 39 feet from the wetland. Further, the proposed erosion control plan demonstrates that adequate measures such as a silt fence, straw wattle, and other necessary protections will be taken to protect surrounding properties from erosion and discharge of pollutants during construction. The biologist's analysis concluded that there would be no significant impacts to wetland ESHA associated with the re -development of the Property and that 39 foot buffer is sufficient for the long-term maintenance and health of the wetland resource. Additionally, since the Project would not affect the wetland directly through dredging, filling, or other alteration, notification and/or permitting under California Department of Fish and Wildlife Section 1602 is not required. Thus, there would be no significant impacts to wetland ESHA associated with the Project. For these reasons, the Project site has no value as habitat for endangered, rare or threatened species. Given the urban character of the surrounding area, no significant impacts to biological resources would occur. (d) Approval of the project would not result in any significant effects relating to traffic, noise, air quality, or water quality. With respect to traffic, an analysis of traffic trips for the Project concluded that the generated trips would not result in a significant traffic impact. Construction of the Project is anticipated to be completed in 2020. The Project is expected to generate 46 trips on a typical weekday, with five (5) morning peak hour trips and seven (7) evening peak hour trips. This represents a 248 trip reduction in average daily trips for the Property when compared to the existing occupied and operating uses. The restaurant is vacant and the office uses are operating at this time and the existing office uses generate 50 average daily trips with 6 AM trips and 6 PM trips. As such, the project -related traffic would not cause or contribute to an unacceptable level of service with the circulation network adjacent to the Project. The Project will provide adequate, convenient parking for employees and customers or visitors based upon the review of the City's Traffic Engineer. Approval of the Project would not result in any significant effect related to traffic or circulation. With respect to noise, an acoustical report prepared March 4, 2019 and updated in February 2020 by Urban Crossroads (Exhibit 2) confirms that sound levels will remain in 21-25 compliance with the noise standards in Section 10.26.025 of the NBMC. The unmitigated Project operational noise levels were estimated to range from 26.7 to 48.2 db(A)' Lege in the worst case. No significant noise impacts will occur and the exterior noise levels would comply with the City's more conservative residential exterior noise standard of 55 dBA Leq for daytime and 50 dBA Leq for nighttime. Therefore, no additional exterior noise abatement measures are required. Additionally, a supplemental noise assessment was provided, which compares the projected project noise to the ambient nighttime noise of four commercial parking areas in the City. The results of the supplemental assessment found similar noise levels to that of the initial analysis and concludes that the initial analysis adequately describes the potential project parking lot noise levels. The Project will comply with all applicable provisions of the City's Noise Ordinance, which allows for construction between specific hours as set forth in Chapter 10.28 of the NBMC. The Project must also be consistent with the City's interior noise standards established in the General Pian Noise Element, including Policy N1.1, N1.2, and N1.5. With respect to air quality, neither short-term nor long-term air pollutant emissions will exceed significance thresholds established by the SCAQMD3. Nonetheless, the Project is required to comply with applicable SCAQMD regulations. Therefore, approval of the Project would not result in any significant effects relating to air quality. With respect to water quality, a preliminary Water Quality Management Plan (Exhibit 3) has been reviewed by the City of Newport Beach and implementation of the Project would not result in potentially significant impacts to the drainage patterns on-site. The Project results in a reduction of impervious surfaces on-site. Water quality objectives will be achieved through the incorporation of Best Managernent Practices (BMPs) identified in the preliminary Water Quality Management Plan (Exhibit 3) during construction and post - project implementation. Project implementation will not change the general drainage pattern of the Property. Current on-site drainage patterns consist of runoff from the front portion of the Property, which is directed into a gravel bed for infiltration prior to discharge to the street. Runoff from the remaining portion of the site will be collected in an area drain system and discharged through a bio -retention planter box at the sides of the property and then pumped to the street for discharge. Under the Project, hardscape, parking structure, and landscape area runoff will be collected in proposed bioretention planter boxes and filter inserts prior to discharge into the underground storm drain system. Approval of the project would not result in any significant effect related to water quality. Furthermore, the existing drainage facilities have adequate capacity to accommodate the increase in surface runoff generated by the proposed project based upon the review by the Project's engineer. (e) The site can be adequately served by all required Utilities and public services. All required utilities, including sewer, water, energy, telephone, etc., exist within the project site. A domestic water service and meter and fire water service and meter are located toward the southwest property line along Avon Street and Riverside Avenue. A ' dB(A) Weights a sound spectrum relative to the sensitivity athe lunnan ear. '- Leq Steady-state "average" sound level over a stated time period ( 15 minute time period per the NBMC), ' littp://www.agmd.-ov/docs/defitult-soui,ce/ccga/handbook/scagind-aii--quality-significance-tlii-esliolds.pdPsfvrsn=2 A-7 21-26 sewer line is located along the southern property line in Avon Street, which drains to a line in Riverside Avenue. A water/waste water calculation has been prepared for the proposed development (Exhibit 4). Project implementation is estimated to utilize less water and waste water than the existing restaurant and office building on-site. Development of a new office and parking structure is estimated to result in a decrease of 3,689 GPD of waste water generation and a decrease of 339 GPD of water demand. No backbone facilities (i.e., master -planned roads and/or utilities) will be required to accommodate the Project. The nearest fire station is one (1) mile south of the Project at 475 32nd Street on the Balboa Peninsula. Furthermore, all of the public services, including police and fire protection, schools and parks and recreation, etc., are adequate to accommodate the proposed project. Thus, the site can be adequately served by all required utilities and public services. Determination CEQA Class 32 consists of projects characterized as in -fill development meeting the conditions described above. The Project consists of the demolition of the existing building and development of a new office building and parking structure with required off-street parking and is consistent with the City's General Plan land use designation General Commercial (GC) and Zoning designations Commercial General (CG) as it provides a resident -serving service use (office tenants) in close proximity to nearby residences and nonresidential uses in the area. The Project is consistent with the General Plan designations and policies, and can be found consistent with all applicable zoning regulations upon approval of the requested applications. The Property is 0.37 acres in size, is located within an urban area, and can be adequately served by all required utilities and public services. An acoustical analysis, preliminary Water Quality Management Plan, and water/waste-water generation memorandum have been prepared. An analysis of the Property indicates that the Property and adjacent areas have no value as habitat for endangered, rare, or threatened species. The Project is expected to have a less than significant impacts related to traffic, noise, air quality, and water quality. As described above, implementation of the Project will not result in any adverse effects on sensitive biological resources, traffic, air quality, noise, or water quality. There is no reasonable probability that the Project will have a significant effect on the environment due to unusual circumstances, nor will the Project result in any short-term or long-term impacts that were not previously considered in the Newport Beach General Plan and General Plan EIR. Therefore, the Project meets all of the conditions described above for in -fill development and qualifies for a Class 32 exemption. Piecemealing As identified in the staff report prepared for the City Council hearing, some commenters claim the "whole of the project" under CEQA should be deemed by the City to include the preliminary application received for the adjacent 2902 West Coast Highway Project for the Garden Restaurant. The Project may, however, be reviewed independent of the Garden Restaurant (PA2019-006) located at 2902 West Coast Highway. 21-27 Under CEQA, generally, the lead agency must consider the "whole of an action" when determining whether it will have significant environmental effects. (CEQA Guidelines, §§ 15003, subd. (h), 15378, subd. (a).} This rule is designed to prevent an agency from "chopping a large project into many tittle ones" that may be individually insignificant but have cumulatively significant environmental effects. Breaking a single project into smaller parts and analyzing those parts separately is often referred to as "piecemealing" or "segmentation." (See also, CEQA Guidelines, §§15165, 15168.) The California Supreme Court has adopted the following test for determining whether unlawful piecemealing has occurred. An agency must analyze a future expansion or other action as part of the initial project "if: (1 ) it is a reasonably foreseeable consequence of the initial project; and (2) the future expansion or action will be significant in that it will likely change the scope or nature of the initial project or its environmental effects." (Laurel Heights Improvement Assn. v. Regents of Univ. of Cal. (19 88) 47 Ca1.3d 376, 396; see also Pub. Resources Code, § 21065 [defining "project"].} Absent these two circumstances, the two proposals are not the same "project" and the lead agency may analyze them separately. There is, therefore, no piecemealing where, as here, two projects serve different purposes, can be implemented independently and/or have different project proponents. In short, the Project and Garden Restaurant demonstrate "independent utility" under CEQA for the following reasons: 1. The City has not received a complete application for the Garden Restaurant; 2. The proposals lack a causal link that makes them part of an overarching scheme, in that the Project does not cause the need forthe Garden Restaurant, and the Garden Restaurant does not cause the need for the Project; and 3. The Project for consideration also does not rely upon the Garden Restaurant in order for its approval and/or implementation. The approval of the Project, for example, would not make approval of the Garden Restaurant proposal either more or less likely. Also, at the October 3, 2019 meeting, the Planning Commission was provided with a Parking Agreement Memorandum of Understanding by the Applicant's attorney entered into between the owner of 2902 West Coast Highway and an adjacent property owner that agreed to provide parking to 2902 West Coast Highway should the project be approved by the City in the future. In the event the City receives a complete application for the Garden Restaurant (PA2019- 006), the City would evaluate the project for full compliance with the City's General Plan, NBMC and CEQA. No substantial evidence in the record demonstrates that consideration of the two proposals independently constitutes improper piecemealing. This is not, for example, a project wherein a developer proposes to consider the potential effects of an infrastructure improvement (i.e. water or sewer) separate from the project itself (i.e. a housing project). If, new substantial evidence is introduced or the Council feels differently, it may refer both applications back to the Planning Commission for concurrent review if deemed appropriate.

One of the allegations raised in the appeal filed by Berding & Weil on behalf of the four adjacent residents was that the Noise Impact Analysis (NIA) prepared by Urban Crossroads, dated April 3, 2019, did not accurately reflect the noise levels anticipated to be generated by the proposed Project. Although the NIA included 24-hour noise measurements taken from an office building in Lake Forest that housed a company that operated 24 hours a day with employees coming and going throughout that 24 hour period, the comment was made that because the parking at 215 Riverside could be used by off-site restaurants or retail uses, the noise from those patrons' cars would be different than the noise from the employees' cars in Lake Forest. In response to that comment, Urban Crossroads took noise measurements from four commercial uses (including two restaurants and two commercial centers with retail and restaurant uses) in the City, The noise measurements f om these uses demonstrate that the original NIA's noise measurements provided an accurate assessment of the noise environment at 215 Riverside. We would appreciate it if you would provide this report to the City Council, and include it in the record of proceedings for the 215 Riverside Project. Very truly yours, St.tsan K.

The purpose of the Supplemental Noise Assessment is to describe the existing noise levels associated with the planned parking lot for the Project. This assessment expands on the previous parking lot reference noise level measurements found in the April 3rd, 2019 215 Riverside Avenue Noise Impact Analysis ("NIA") prepared by Urban Crossroads, Inc. (1) PREVIOUS FINDINGS OF THE 215 RIVERSIDE AVENUE NOISE IMPACT ANALYSIS The results of the original April 3rd, 2019 NIA indicated that the highest noise levels that would affect the adjacent noise -sensitive residential receiver locations are expected to approach 38.2 dBA Lecl from parking lot vehicle movements and 57.2 dBA Leq from HVAC units when measured at a distance of 50 feet. The NIA demonstrated that the noise generated from the expected Project operational noise sources (roof -top air conditioning and parking lot vehicle movements) will satisfy the City of Newport Beach Municipal Code daytime 55 dBA Leq and nighttime 50 dBA Leq exterior noise level standards at the neighboring residential uses. Based on the findings in the NIA, no additional exterior noise abatement measures (e.g., noise barriers or operational mitigation measures) are required. The reference noise level measurements from the original NIA used to describe the Project noise levels are shown in Table 1 below.

Moreover, the analysis assumed that the highest reference noise source activity for all noise sources operate every minute of every hour in each day. Therefore, the analysis includes no periods of inactivity, and describes the continuous operation of operational noise source activities across both daytime and nighttime hours. In reality the noise level impacts will likely vary throughout the day. For example, rooftop air conditioning will not be operating at night for the 215 Riverside Avenue building. In addition, at the October 17, 2019 Planning Commission hearing the project proponent agreed to extend the rooftop trellis and prohibit parking on the upper parking level after 11:00 pm. Any cars on the upper parking level parked before 11:00 pm would be allowed to remain. The upper parking level restrictions would also contribute to reducing potential noise levels associated with parking activities. REFERENCE NOISE LEVEL MEASUREMENTS As previously indicated, the purpose of this assessment is to supplement the existing parking lot reference noise level measurements with additional noise level measurement data describing similar parking lots in area. To identify the potential parking lot noise levels from the Project, long-term reference noise level measurements were collected at the following locations as shown on Exhibit A: • Mariner's Mile Square Parking Lot • On the Rocks Bar and Grill Parking Lot • Parking Lot at West Oceanfront and 22nd Street • The Landing Parking Lot MEASUREMENT PROCEDURES To assess the potential noise levels generated by the proposed Project parking lot, reference noise level measurements were collected between 11:00 a.m. on Friday, December 131h, 2019 to 8:00 a.m. on Sunday, December 16th, 2019. Appendix A includes photographs of the reference parking lot activities. The long-term noise level measurements were recorded using Piccolo Type 2 integrating sound level meter and dataloggers. The sound level meter was calibrated using a Larson -Davis calibrator, Model CAL 200. All noise meters were programmed in "slow" mode to record noise levels in "A" weighted form. The sound level meters and microphones were equipped with a windscreen during all measurements. All noise level measurement equipment satisfies the American National Standards Institute (ANSI) standard specifications for sound level meters ANSI S1.4-2014/IEC 61672-1:2013.

The four supplemental noise levels at similar reference parking lots in the City of Newport Beach ranged from 35.7 dBA Leq to 40.5 dBA Leq at 50 feet during the peak nighttime hours. This is generally consistent with the original NIA parking lot reference noise level measurement of 38.2 dBA Leq from the Panasonic Avionics Corporation parking lot. It is also important to recognize that while this assessment focuses on parking lot noise level impacts, the primary operational noise source activity of 57.2 dBA Leq is related to the HVAC units, which will not be operating at night. In effect, the reference noise levels of 38.2 dBA Leq associated with the parking lot are largely overshadowed by the HVAC.operational noise levels of 57.2 dBA Leq, which will not operate at night. This Supplemental Noise Assessment demonstrates that original parking lot reference noise level of 38.2 dBA Leq adequately reflects the reference noise source levels ranging from 35.7 to 40.5 dBA Leq at similar parking lots in Newport Beach. Therefore, the analysis in the original NIA adequately describes the potential parking lot noise level impacts at the nearby noise sensitive residential land use.

(1) The Project site is located at 215 Riverside Avenue in the City of Newport Beach, and consists of a two-story commercial building with attached two-level parking structure. Using reference noise levels of conservatively -representative operational activities, including roof -top air conditioning units and parking structure vehicle movements, this analysis estimates the Project - related operational (stationary -source) noise levels at the nearby noise -sensitive residential homes and adjacent commercial uses, consistent with the City of Newport Beach Municipal Code. The City of Newport Beach Municipal Code identifies base exterior noise level standards which do not account for the existing ambient noise level. If existing ambient noise levels in the Project study area are higher than the base exterior standards, the ambient noise levels become the adjusted exterior noise level standards per Section 10.26.025 (A) of the City of Newport Beach Municipal Code. As such, to present a conservative approach, this analysis relies on the more restrictive base exterior noise level standards of 55 dBA LeQ daytime and 50 dBA Leq nighttime at residential uses per the City of Newport Beach Municipal Code; rather than adjusted exterior noise levels based on higher existing ambient noise levels measured in the Project study area which ranged from 54.8 to 63.2 dBA I.eq during the daytime, and 47.2 to 59.6 dBA L.eq during the nighttime hours, as shown in Table 4-1 of this report. Moreover, it is important to note that the Project operational noise levels described in this report assume a worst-case noise environment with the Project's roof -top air conditioning units and parking structure vehicle movements operating continuously throughout the daytime and nighttime hours. However, the noise levels associated with the Project are anticipated to vary throughout the day under typical operating conditions. The results of this conservative analysis show that the Project -related operational noise levels associated with roof -top air conditioning units and parking structure vehicle movements will remain below the City of Newport Beach Municipal Code daytime and nighttime exterior noise level standards at the nearby noise -sensitive residential homes and adjacent commercial uses. Therefore, no additional exterior noise abatement measures (e.g., noise barriers) are required. 12356-04 Noise Study O URBAN 1 CROSSROADS 21-50 215 Riverside Avenue Noise Impact Analysis This page intentionally left blank 12356-04 Noise Study O URBAN CROSSROADS 21-51 215 Riverside Avenue Noise Impact Analysis 1 INTRODUCTION This noise analysis has been completed to evaluate the potential future operational noise levels associated with the operation of a two-story commercial office building with attached parking structure at 215 Riverside Avenue ("Project"), and to identify the necessary exterior noise abatement measures, if any, to satisfy the City of Newport Beach Municipal Code exterior noise level standards. (1) This noise study describes the Project, provides information regarding noise fundamentals, outlines the local regulatory setting, provides the study methods and procedures for operational noise analysis, and evaluates the operational noise levels from the Project. 1.1 SITE LOCATION The Project is located at 215 Riverside Avenue in the City of Newport Beach, as shown on Exhibit 1-A. Existing noise -sensitive uses in the Project study area include residential homes to the north and east. It is important to note that the residential homes to the north and east of the Project site are situated at a higher elevation than the 215 Riverside Avenue site. Commercial uses in the Project study area are located to the west and south of the Project site. 1.2 PROJECT DESCRIPTION The Project consists of two-story commercial building with attached two-level parking structure.

Sound becomes unwanted when it interferes with normal activities, when it causes actual physical harm or when it has adverse effects on health. Noise is measured on a logarithmic scale of sound pressure level known as a decibel (dB). A -weighted decibels (dBA) approximate the subjective response of the human ear to broad frequency noise source by discriminating against very low and very high frequencies of the audible spectrum. They are adjusted to reflect only those frequencies which are audible to the human ear. Exhibit 2-A presents a summary of the typical noise levels and their subjective loudness and effects that are described in more detail below.

The scale for measuring intensity is the decibel scale. Each interval of 10 decibels indicates a sound energy ten times greater than before, which is perceived by the human ear as being roughly twice as loud. (2) The most common sounds vary between 40 dBA (very quiet) to 100 dBA (very loud). Normal conversation at three feet is roughly at 60 dBA, while loud jet engine noises equate to 110 dBA 12356-04 Noise Study 40/ URBAN 7 CROSSROADS 21-56 215 Riverside Avenue Noise Impact Analysis at approximately 100 feet, which can cause serious discomfort. (3) Another important aspect of noise is the duration of the sound and the way it is described and distributed in time. 2.2 NOISE DESCRIPTORS Environmental noise descriptors are generally based on averages, rather than instantaneous, noise levels. The most commonly used figure is the equivalent level (L,,q). Equivalent sound levels are not measured directly but are calculated from sound pressure levels typically measured in A - weighted decibels (dBA). The equivalent sound level (L,qj represents a steady state sound level containing the same total energy as a time varying signal over a given sample period and is commonly used to describe the "average" noise levels within the environment. While sound pressure levels (e.g. Leq) quantify in decibels the intensity of given sound sources at a reference distance, sound power levels (PWL) are connected to the sound source and are independent of distance. Sound pressure levels vary substantially with distance from the source, and also diminish as a result of intervening obstacles and barriers, air absorption, wind and other factors. Sound power is the acoustical energy emitted by the sound source and is an absolute value that is not affected by the environment. 2.3 SOUND PROPAGATION When sound propagates over a distance, it changes in level and frequency content. The manner in which noise reduces with distance depends on the following factors. 2.3.1 GEOMETRIC SPREADING Sound from a localized source (i.e., a stationary point source) propagates uniformly outward in a spherical pattern. The sound level attenuates (or decreases) at a rate of 6 dB for each doubling of distance from a point source. Highways consist of several localized noise sources on a defined path and hence can be treated as a line source, which approximates the effect of several point sources. Noise from a line source propagates outward in a cylindrical pattern, often referred to as cylindrical spreading. Sound levels attenuate at a rate of 3 dB for each doubling of distance from a line source. (4) 2.3.2 GROUND ABSORPTION The propagation path of noise from a highway to a receiver is usually very close to the ground. Noise attenuation from ground absorption and reflective wave canceling adds to the attenuation associated with geometric spreading. Traditionally, the excess attenuation has also been expressed in terms of attenuation per doubling of distance. This approximation is usually sufficiently accurate for distances of less than 200 ft. For acoustically hard sites (i.e., sites with a reflective surface between the source and the receiver, such as a parking lot or body of water), no excess ground attenuation is assumed. For acoustically absorptive or soft sites (i.e., those sites with an absorptive ground surface between the source and the receiver such as soft dirt, grass, or scattered bushes and trees), an excess ground attenuation value of 1.5 d6 per doubling of distance is normally assumed. When added to the cylindrical spreading, the excess ground 12356-04 Noise Study _ L% URBAN CROSSROADS 21-57 215 Riverside Avenue Noise Impact Analysis attenuation results in an overall drop-off rate of 4.5 d6 per doubling of distance from a line source. (5) 2.3.3 ATMOSPHERIC EFFECTS Receivers located downwind from a source can be exposed to increased noise levels relative to calm conditions, whereas locations upwind can have lowered noise levels. Sound levels can be increased at large distances (e.g., more than 500 feet) due to atmospheric temperature inversion (i.e., increasing temperature with elevation). Other factors such as air temperature, humidity, and turbulence can also have significant effects. (4) 2.3.4 SHIELDING A large object or barrier in the path between a noise source and a receiver can substantially attenuate noise levels at the receiver. The amount of attenuation provided by shielding depends on the size of the object and the frequency content of the noise source. Shielding by trees and other such vegetation typically only has an "out of sight, out of mind" effect. That is, the perception of noise impact tends to decrease when vegetation blocks the line -of -sight to nearby resident. However, for vegetation to provide a substantial, or even noticeable, noise reduction, the vegetation area must be at least 15 feet in height, 100 feet wide and dense enough to completely obstruct the line -of sight between the source and the receiver. This size of vegetation may provide up to 5 dBA of noise reduction. The FHWA does not consider the planting of vegetation to be a noise abatement measure. (5) 2.4 NOISE CONTROL Noise control is the process of obtaining an acceptable noise environment for an observation point or receiver by controlling the noise source, transmission path, receiver, or all three. This concept is known as the source -path -receiver concept. (6) In general, noise control measures can be applied to these three elements. Exhibit 2-13 shows the source -path -receiver concept. 2.5 NOISE BARRIER ATTENUATION Effective noise barriers can reduce noise levels by 10 to 15 dBA, cutting the loudness of traffic noise in half. A noise barrier is most effective when placed close to the noise source or receiver. Noise barriers, however, do have limitations. For a noise barrier to work, it must be high enough and long enough to block the path of the noise source.

Several factors are related to the level of community annoyance including: • Fear associated with noise producing activities; • Socio-economic status and educational level; • Perception that those affected are being unfairly treated; • Attitudes regarding the usefulness of the noise -producing activity; • Belief that the noise source can be controlled. Approximately ten percent of the population has a very low tolerance for noise and will object to any noise not of their making. Consequently, even in the quietest environment, some complaints will occur. Another twenty-five percent of the population will not complain even in very severe noise environments. Thus, a variety of reactions can be expected from people exposed to any given noise environment. (7) Surveys have shown that about ten percent of the people exposed to traffic noise of 60 dBA will report being highly annoyed with the noise, and each increase of one dBA is associated with approximately two percent more people being highly annoyed. When traffic noise exceeds 60 dBA or aircraft noise exceeds 55 dBA, people may begin to complain. (7) Despite this variability in behavior on an individual level, the population can be expected to exhibit the following responses to changes in noise levels as shown on Exhibit 2-C. An increase or decrease of 1 dBA cannot be perceived except in carefully controlled laboratory experiments, a change of 3 dBA are considered barely perceptible, and changes of 5 dBA are considered readily perceptible.

In most areas, automobile and truck traffic is the major source of environmental noise. Traffic activity generally produces an average sound level that remains fairly constant with time. Air and rail traffic, and commercial and industrial activities are also major sources of noise in some areas. Federal, state, and local agencies regulate different aspects of environmental noise. Federal and state agencies generally set noise standards for mobile sources such as aircraft and motor vehicles, while regulation of stationary sources is left to local agencies. 3.1 CITY OF NEWPORT BEACH MUNICIPAL CODE NOISE STANDARDS The City of Newport Beach Municipal Code, Chapter10.26 Community Noise Control, establishes the permissible exterior noise levels that may intrude into a neighboring property. According to Section 10.26.025(A) exterior noise levels at single-family residential land uses (Noise Zone 1) shall not exceed 55 dBA Leq during the daytime hours (7:00 a.m. to 10:00 p.m.) and 50 dBA Leq during the nighttime hours {10:00 p.m. to 7:00 a.m.). (1) For commercial uses, exterior noise levels shalt not exceed 65 dBA Leq during the daytime hours (7:00 a. m. to 10:00 p.m.) and 60 dBA Leg during the nighttime hours (10:00 p.m. to 7:00 a.m.)- The City of Newport Beach Municipal Code, Chapter10.26 Community Noise Controlexterior noise level standards are shown on Table 3-1 and are included in Appendix 3.1.

The receiver locations were selected to describe and document the existing noise environment within the Project study area. Exhibit 4-A provides the boundaries of the Project study area and the noise level measurement locations. To fully describe the existing noise conditions, noise level measurements were collected by Urban Crossroads, Inc. on Tuesday, February 26th, 2019. Appendix 4.1 includes study area photos. 4.1 MEASUREMENT PROCEDURE AND CRITERIA To describe the existing noise environment, the hourly noise levels were measured during typical weekday conditions over a 24-hour period. By collecting individual hourly noise level measurements, it is possible to describe the daytime and nighttime hourly noise levels and calculate the 24-hour CNEL. The long-term noise readings were recorded using Piccolo Type 2 integrating sound level meter and dataloggers. The Piccolo sound level meters were calibrated using a Larson -Davis calibrator, Model CAL 150. All noise meters were programmed in "slow" mode to record noise levels in "A" weighted form. The sound level meters and microphones were equipped with a windscreen during all measurements. All noise level measurement equipment satisfies the American National Standards Institute (ANSI) standard specifications for sound level meters ANSI 51.4-2014/IEC 61672-1:2013. (8) 4.2 NOISE MEASUREMENT LOCATIONS The long-term noise level measurements were positioned as close to the nearest sensitive receiver locations as possible to assess the existing ambient hourly noise levels surrounding the Project site. Both Caltrans and the FTA recognize that it is not reasonable to collect noise level measurements that can fully represent every part of a private yard, patio, deck, or balcony normally used for human activity when estimating impacts for new development projects. This is demonstrated in the Caltrans general site location guidelines which indicate that, sites must be free of noise contamination by sources other than sources of interest. Avoid sites located near sources such as barking dogs, lawnmowers, pool pumps, and air conditioners unless it is the express intent of the analyst to measure these sources. (4) Further, FTA guidance states, that it is not necessary nor recommended that existing noise exposure be determined by measuring at every noise -sensitive location in the project area. Rather, the recommended approach is to characterize the noise environment for clusters of sites based on measurements or estimates at representative locations in the community. (9) Based on recommendations of Caltrans and the FTA, it is not necessary to collect measurements at each individual building or residence, because each receiver measurement represents a group of buildings that share acoustical equivalence. (9) In other words, the area represented by the receiver shares similar shielding, terrain, and geometric relationship to the reference noise source. Receivers represent a location of noise sensitive areas and are used to estimate the future noise level impacts. Collecting reference ambient noise level measurements at the nearby 12356-04 Noise Study L% URBAN is CROSSROADS 21-64 215 Riverside Avenue Noise Impact Analysis sensitive receiver locations allows for a comparison of the before and after Project noise levels and is necessary to assess potential noise impacts due to the Project's contribution to the ambient noise levels. 4.3 NOISE MEASUREMENT RESULTS The noise measurements presented below focus on the average or equivalent sound levels (Leq). The equivalent sound level (Leq) represents a steady state sound level containing the same total energy as a time varying signal over a given sample period. Table 4-1 identifies the hourly daytime (7:00 a.m. to 10:00 p.m.) and nighttime (10:00 p.m. to 7:00 a.m.) noise levels at each noise level measurement location. Appendix 4.2 provides a summary of the existing hourly ambient noise levels described below: • Location Ll represents the noise levels northwest of the Project site on Cliff Drive in an existing park near residential homes. The energy (logarithmic) average daytime noise level was calculated at 55.7 dBA Leq with an average nighttime noise level of 50.0 dBA Leq. • Location L2 represents the noise levels within the existing parking lot at the Project site, south of existing residential homes. The energy (logarithmic) average daytime noise level was calculated at 54.8 dBA Leq with an average nighttime noise level of 47.2 dBA Leq. • Location L3 represents the noise levels on northeast of the Project site on Riverside Avenue adjacent to an existing park. The energy (logarithmic) average daytime noise level was calculated at 63.2 dBA Leq with an average nighttime noise level of 59.6 dBA Leq. • Location L4 represents the noise levels east of the Project site on Ocean View Avenue adjacent to existing residential homes. The energy (logarithmic) average daytime noise level was calculated at 56.2 dBA Leq with an average nighttime noise level of 48.7 dBA Leq. Table 4-1 provides the (energy average) noise levels used to describe the daytime and nighttime ambient conditions. These daytime and nighttime energy average noise levels represent the average of all hourly noise levels observed during these time periods expressed as a single number. Appendix 4.2 provides summary worksheets of the noise levels for each hour as well as the minimum, maximum, Ll, L2, Ls, LB, Les, Lso, L9o, L9s, and L99 percentile noise levels observed during the daytime and nighttime periods. The background ambient noise levels in the Project study area are dominated by the transportation -related noise associated the arterial roadway network. This includes the auto and heavy truck activities on study area roadway segments near the noise level measurement locations.

This section provides a description of the reference noise level measurements shown on Table 5-1 used to estimate the Project operational noise impacts. It is important to note that the following projected noise levels assume the worst-case noise environment with the roof -top air conditioning units and parking structure vehicle movements all operating continuously. These noise level impacts will likely vary throughout the day. TABLE 5-1: REFERENCE NOISE LEVEL MEASUREMENTS Noise Source Total Ref.

"Daytime" = 7:00 a.m. to 10:00 p.m.; "Nighttime" = 10:00 p.m. to 7:00 a.m. 5.1.1 ROOF -TOP AIR CONDITIONING UNITS To assess the impacts created by the roof -top air conditioning units at the Project buildings, reference noise levels measurements were taken over a four-day total duration at the Santee Walmart on July 27th, 2015. Located at 170 Town Center Parkway in the City of Santee, the noise level measurements describe mechanical roof -top air conditioning units on the roof of an existing Walmart store, in addition to background noise levels from additional roof -top units. The reference noise level represents Lennox SCA120 series 10 -ton model packaged air conditioning units. At 5 feet from the closest roof -top air conditioning unit, the highest exterior noise level from all four days of the measurement period was measured at 77.2 dBA Leq. Using the uniform reference distance of 50 feet, the noise level is 57.2 dBA Leq. The operating conditions of the reference noise level measurement reflect peak summer cooling requirements with measured temperatures approaching 96 degrees Fahrenheit (°F) with average daytime temperatures of 82°F. This reference noise level measurement is anticipated to conservatively overstate the roof- top air conditioning unit noise levels of the Project since it represents the cooling equipment of a larger, commercial -retail box store. 12356-04 Noise Study LS / URBAN 19 CROSSROADS 21-68 215 Riverside Avenue Noise 5.2.2 PARKING STRUCTURE VEHICLE MOVEMENTS To determine the noise levels associated with parking structure vehicle movements, Urban Crossroads collected reference noise level measurements over a 24-hour period on May 17th, 2017 at the parking lot for the Panasonic Avionics Corporation in the City of Lake Forest. The peak hour of activity measured over the 24-hour noise level measurement period occurred between 12:00 p.m. to 1:00 p.m., or the typical lunch hour for employees working in the area. The measured, peak -hour reference noise level at 50 feet from the parking activity was measured at 38.2 dBA Leq. The parking activity noise levels are mainly due to cars pulling in and out of spaces during peak lunch hour activity and employees talking. This reference noise level measurement is anticipated to conservatively overstate the parking structure noise levels of the Project since it represents the parking activity associated with that of a larger, commercial office use with a greater number of parking spaces. 5.2.3 WORST -WE PROJECT OPERATIONAL NOISE LEVELS As previously indicated, it is important to note that the Project operational noise levels provided in this study assume a conservative estimation of the future noise environment, with the roof- top air conditioning units and parking structure vehicle movements all operating continuously, and simultaneously. Moreover, this analysis assumes that the highest reference noise source activity for all noise sources is operating every minute of every hour in a given day. Therefore, the analysis assumes no periods of inactivity, and assumes consistent operation across both daytime and nighttime hours. In reality, these noise level impacts will likely vary throughout the day. 5.2 CADNAA NOISE PREDICTION MODEL To fully describe the exterior operational noise levels from the 215 Riverside Avenue, Urban Crossroads, Inc. developed a noise prediction model using the CadnaA (Computer Aided Noise Abatement) computer program. CadnaA can analyze the noise level of multiple types of noise sources and calculates the noise levels at any location using the spatially accurate Project site plan and includes the effects of topography, buildings, and multiple barriers in its calculations using the latest standards to predict outdoor noise impacts. Using the spatially accurate Project site plan and flown aerial imagery from Nearmap, a CadnaA noise prediction model of the Project study area was developed. The noise model provides a three-dimensional representation of the Project study area using the following key data inputs: • Ground absorption; • Reflections at buildings and barriers; • Reference noise level sources by type (area, point, etc.) and noise source height; • Multiple noise receiver locations and heights; • Barrier and building heights. 12356-04 Noise Study L Fo URBAN 20 CROSSROADS 21-69 215 Riverside Avenue Noise Impact Analysis Based on these data inputs, the CadnaA noise prediction model will calculate the distance from each noise source to the noise receiver locations, using the ground absorption, distance, and harrier/building attenuation inputs to provide a summary of noise level calculations at each receiver location and the partial noise level contributions by noise source. The reference sound power level (PWL) for the highest noise source expected at the Project site was input into the CadnaA noise prediction model. While sound pressure levels (e.g. L,q) quantify in decibels the intensity of given sound sources at a reference distance, sound power levels (PWL) are connected to the sound source and are independent of distance. Sound pressure levels vary substantially with distance from the source, and also diminish as a result of intervening obstacles and barriers, air absorption, wind, and other factors. Sound power is the acoustical energy emitted by the sound source and is an absolute value that is not affected by the environment, The sound power level used in this analysis has been calibrated in the noise prediction model to accurately describe the reference dBA Leq noise levels. Based on the technical guidance provided for CadnaA, (10) the reference noise source is created in a separate CadnaA noise model with a receiver at the reference distance of the noise level measurement. The PWL of the noise source is then adjusted in the separate CadnaA noise model until the noise level at the given reference distance equals the measured reference noise level. The operational noise level calculations provided in this noise study account for the distance attenuation provided due to geometric spreading, when sound from a localized stationary source (i.e., a point source) propagates uniformly outward in a spherical pattern. Soft site conditions are used in the operational noise analysis which result in noise levels that attenuate (or decrease) at a rate of 7.5 dBA for each doubling of distance from a point source, given the soft ground and vegetation Between the Project site and adjacent sensitive receiver locations. Appendix 6.1 includes the CadnaA noise model inputs and calculation data. 12355.04 Norse Study 71 [fir URBAN 21-70 215 Riverside Avenue Noise Impact Analysis This page intentionally left blank 12356-04 Noise Study O URBAN ZZ CROSSROADS 21-71 215 Riverside Avenue Noise Impact Analysis 6 OPERATIONAL IMPACTS This section analyzes the potential operational noise levels due to the Project's stationary noise sources at the adjacent residential and commercial receiver locations. Exhibit 6-A shows the noise source and receiver locations used to assess the Project -related operational noise levels generated by roof -top air conditioning units and parking structure vehicle movements. Based on the reference noise level measurements, previously described in Section 5.1, the Project operational stationary -source noise levels are estimated at each of the nearby receiver locations. All operational noise level calculations include the noise barrier attenuation provided by the planned parapet walls, Project building, existing buildings, and topography in the Project study area, as shown on Exhibit 6-A. Table 6-1 shows the Project -only noise levels at receiver locations R1 to R7 range from 26.7 to 48.2 dBA Leq 'based on the reference noise levels used in the analysis. At receiver locations R1 to 115, which represent noise -sensitive residential uses, the Project operational noise levels range from 26.7 to 48.2 dBA Leq, and are shown to satisfy the City of Newport Beach Municipal Code daytime 55 dBA Leq and nighttime 50 dBA Leq exterior noise level standards For residential uses. At receiver locations R6 and R7, which represent existing commercial uses, the Project operational noise levels range from 37.4 to 37.9 d6A Leq, and are shown to satisfy the City of Newport Beach Municipal Code daytime 65 dBA Leq and nighttime 60 dBA Leq exterior noise level standards for commercial uses. Therefore, the results of the analysis show that the Project - related operational noise levels associated with roof -top air conditioning units and parking structure vehicle movements will satisfy the City of Newport Beath Municipal Code daytime and nighttime base exterior noise level standards at the nearby noise -sensitive residential homes and adjacent commercial uses. As such, no additional exterior noise abatement measures (e.g., noise barriers) are required.

SITE DESIGN AND DRAINAGE PLAN Overview The ultimate plan of development for the proposed project is shown on the WQMP Site Plan in Section VI of this report. The project Precise Grading Plan shows the proposed grading, site improvements, and retaining walls necessary for construction of a single-family residence. Site Design Practices The project incorporates Site Design practices as follows: Preserve Existing Drainage Patterns and Time of Concentration - The ultimate points of discharge are the same for the pre- and post -project conditions. Time of concentration will be similar, since pre -and post -project flow path lengths will be similar. Drainage Management Areas (DMAs) There is one (1) Drainage Management Area (DMA) for this commercial development. The following LID BMP will be used to meet the calculated Design Volume for the DMA: - Bioretention with Underdrain (Biotreatment BMP) DM Area (sq. BMP Type Sizing A ft.) Impervious BIO -1: Bioretention w/ 1 14,470 0.77 SWQDv Underdrain See discussion for the selected BMP in Section IV.3. See the WQMP Site Plan provided in Section VI of this report for DMA location and characteristics. The GIS coordinates for all BMPs are nearIy identical at: 33.6219, -117.9237. MR.

Implementation of said controls is discussed in the text that follows. Name Included? Localized on -lot infiltration ❑ Impervious area dispersion (e.g. roof top disconnection) ❑ Street trees (canopy interception) ❑ Residential rain barrels (not actively managed) ❑ Green roofs/Brown roofs ❑ Blue roofs ❑ Impervious area reduction (e.g. permeable pavers, site design) ❑ Other: ❑ Hydrologic Source Controls have not been used due to space constraints, including landscape area size and proximity to structure foundations. MR. GARY JABARA Section N Page 14 21-121 Water Quality Management Plan (WQMP) 215 Riverside Avenue, Newport Beach, California IV.3.2 Infiltration BMPs Infiltration BMPs to be used for this project are indicated in the table below. Implementation of said controls is discussed in the text that follows. Name Included? Bioretention without underdrains ❑ Rain gardens ❑ Porous landscaping ❑ Infiltration planters ❑ Retention swales ❑ Infiltration trenches Infiltration basins ❑ Drywells ❑ Subsurface infiltration galleries ❑ French drains ❑ Permeable asphalt ❑ Permeable concrete ❑ Permeable concrete pavers ❑ Other: ❑ It is believed that infiltration will not be feasible for this project due to the Type "D" site soils. Further analysis will be done when the soils report becomes available. MR. GARY 3ABARA Section N Page 15 21-122 Water Quality Management Plan (WQMP) Z15 Riverside Avenue, Newport Beach, California Table 2.7: Infiltration BMP Feasibility Worksheet Provide basis - Infiltration BMPs will not pose a significant risk to local groundwater. Groundwater in the vicinity of the project site is not used for drinking water. Pretreatment devices will mitigate entry of trash, sediment, and oil R grease into proposed infiltration BMPs. Would Infiltration BMPs pose significant risk of increasing risk of geotechnical hazards that cannot be mitigated to an acceptable level? (Yes if the answer to any of the following questions is yes, as established by a geotechnical expert): • The BMP can only be located less than 50 feet away 2 from slopes steeper than 15 percent X • The BMP can only be located less than eight feet from building foundations or an altemative setback. A study prepared by a geotechnical professional or an available watershed study substantiates that starmwater infiltration would potentially result in significantly increased risks of geotechnical hazards that cannot be mitigated to an acceptable level. Provide basis: 3 I Would infiltration of the DCV from drainage area violatef f x downstream water rights?

Biotreatment BLIP Fact Sheets (BIO) Conceptual criteria for biotreatment BMP selection, design, and maintenance are contained in Appendix Xll. 'Mese criteria are generally: applicable to the design of biotreatment Bi Il's in Orange Count\, and Bkll-'-specific guidance is provided in the following fact sheets. 24 ;Note: Blotreatm.ent 13MPs shall he designed to provide the maximum feasible infilhfation and F."l ` based on criteria contained in Appendix X1.2. BIO -1: Bioretention with Underdrains Bioretention stormwater treatment facilities are landscaped shallow depressions that capture and filter stormwater runoff. These facilities function as a soil and plant -based filtration device that removes pollutants through a variety of physical, biological, and chemical treatment processes. The facilities normally consist of a ponding area, mulch layer, planting soils, and plants. As stormwater passes down through the planting soil, pollutants are filtered, adsorbed, biodegraded, and sequestered by the soil and plants. Bioretention with an underdrain are utilized for areas with low permeability native soils or steep slopes where the underdrain system that routes the heated runoff to the storm drain system rather than depending entirely on infiltration. Bioretention must be designed without an underdrain in areas of high soil permeability. Screening Considerations Y Rain gardens with underdrains Vegetated media filter ➢ Downspout planter boxes Bioretention Source: Geosyntec Consultants If there are no hazards associated with infiltration (such as groundwater concerns, contaminant plumes or geotechnical concerns); bioinfiltration facilities, which achieve partial infiltration; should be used to maximize infiltration. '" Not all W\IPs presented in this section are considered "biofiltration B.Mlls" under the South Orange County Permit Area. Bioliltration B.MPs are vegetated treat -and -release 13.\IPs that filter stormwater through amended soil media that is biologically active, support plant growth, and also promote infiltration andor evapotranspiration. For projects in South Orange County, the total volume of storage in surface ponding and pores spaces is required to be at least 7�'X, of the remaining DCV that the biofiltration BLIP is designed to address. This prevents significant dovNn- sizing of'BJIPs which otherwise may be possible via routing calculations. Biotreatment ByIPs that do not meet this definition are not considered to be 1.11) B.Mlls, but may be used as treatment control or prc-treatment WMI's. See Section 111.7 and Worksheet SOC- I for guidance. December 20, 2013 21-146 TECHNICAL GUIDANCE DOCUMENT APPENDICES • Bioretention with underdrain facilities should be lined if contaminant plumes or geotechnical concerns exist. If high groundwater is the reason for infiltration infeasibility, bioretention facilities with underdrains do not need to be lined. Opportunity Criteria • Land use may include commercial, residential, mixed use, institutional, and subdivisions. Bioretention may also be applied in parking lot islands, cul-de-sacs, traffic circles, road shoulders, road medians, and next to buildings in planter boxes. • Drainage area is15 5 acres. Area is available for infiltration. • Site must have adequate relief between land surface and the stormwater conveyance system to permit vertical percolation through the soil media and collection and conveyance in underdrain to stormwater conveyance system. OC-Specirrc Design Criteria and Considerations El greater depth should not exceed 18 inches; fencing may be required if ponding depth is greater than 6 inches to mitigate drowning. The minimum soil depth is 2 feet (3 feet is preferred). El drawdown maximum drawdown time of the bioretention ponding area is 48 hours. The maximum drawdown time of the planting media and gravel drainage layer is 96 hours, if applicable. Infiltration pathways may need to be restricted due to the close proximity of roads, foundations, ❑or other infrastructure. A geomembrane liner, or other equivalent water proofing, may be placed along the vertical walls to reduce lateral flows. This liner should have a minimum thickness of 30 mils. If infiltration in bioretention location is hazardous due to groundwater or geotechnical concerns, a geomembrane liner must be installed at the base of the bioretention facility. This liner should have a minimum thickness of 30 mils. ElThe planting media placed in the cell shall be designed per the recommendations contained in MISC-1: Planting/Storage Media Plant materials should be tolerant of summer drought, ponding fluctuations, and saturated soil conditions for 48 hours; native place species and/or hardy cultivars that are not invasive and do not require chemical inputs should be used to the maximum extent feasible ❑The bioretention area should be covered with 2-4 inches (average 3 inches) or mulch at the start and an additional placement of 1-2 inches of mulch should be added annually. Underdrain should be sized with a 6 inch minimum diameter and have a 0.5% minimum slope. Underdrain should be slotted polyvinyl chloride (PVC) pipe; underdrain pipe should be more than 5 feet from tree locations (if space allows). ❑A gravel blanket or bedding is required for the underdrain pipe(s). At least 0.5 feet of washed aggregate must be placed below, to the top, and to the sides of the underdrain pipe(s). An overflow device is required at the top of the bioretention area ponding depth. ❑Dispersed flow or energy dissipation (i.e. splash rocks) for piped inlets should be provided at basin inlet to prevent erosion. ❑Ponding area side slopes shall be no steeper than 3:1 (H:V) unless designed as a planter box BMP with appropriate consideration for trip and fall hazards. XIV -;1 December 20, 2013 21-147 TECHNICAL GUIDANCE DOCUMENT APPENDICES Simple Sizing Method for Bioretention with Underdrain If the Simple Design Capture Volume Sizing Method described in Appendix 111.3.1 is used to size a bioretention with underdrain facility, the user selects the basin depth and then determines the appropriate surface area to capture the DCV. The sizing steps are as follows: Step 1: Determine DCV Calculate the DCV using the Simple Design Capture Volume Sizing Method described in Appendix 111.3.1. Step 2: Verify that the Ponding Depth will Draw Down within 48 Hours The ponding area drawdown time can be calculated using the following equation: DDp = (dp / KMEDIA) X 12 in/ft Where: DDp = time to drain ponded water, hours dp = depth of ponding above bioretention area, ft (not to exceed 1.5 ft) KMEDIA = media design infiltration rate, in/hr (equivalent to the media hydraulic conductivity with a factor of safety of 2; KMEDIA of 2.5 in/hr should be used unless other information is available) If the drawdown time exceeds 48 hours, adjust ponding depth and/or media infiltration rate until 48 hour drawdown time is achieved. Step 3: Determine the Depth of Water Filtered During Design Capture Storm The depth of water filtered during the design capture storm can be estimated as the amount routed through the media during the storm, or the ponding depth, whichever is smaller. dFILTERED — Minimum [ ((KNIEDIA X TROUTING)/12), dp] Where: dFILTERED = depth of water that may be considered to be filtered during the design storm event, ft KNIEDIA = media design infiltration rate, in/hr (equivalent to the media hydraulic conductivity with a factor of safety of 2; Kr,,IED,A of 2.5 in/hr should be used unless other information is available) TROUTING = storm duration that may be assumed for routing calculations; this should be assumed to be no greater than 3 hours. If the designer desires to account for further routing effects, the Capture Efficiency Method for Volume -Based, Constant Drawdown BMPs (See Appendix 111.3.2) should be used. dp = depth of ponding above bioretention area, ft (not to exceed 1.5 ft) Step 4: Determine the Facility Surface Area A = DCV/ (dp + dFILTERED) Where: A = required area of bioretention facility, sq -ft DCV = design capture volume, cu -ft dFILTFRED = depth of water that may be considered to be filtered during the design storm event, ft dp = depth of ponding above bioretention area, ft (not to exceed 1.5 ft) In South Orange County, the provided ponding plus pore volume must be checked to demonstrate that it is greater than 0.75 of the remaining DCV that this BMP is designed to address. See Section 111.7 and Worksheet SOC -1. XI\I-52 December 20,20-13 21-148 TECHMC:\L GliiDANCE DOCUMENT APPENDICES Capture Efficiency Method for Bioretention with Underdrains If the bioretention geometry has already been defined and the user wishes to account more explicitly for routing, the user can determine the required footprint area using the Capture Efficiency Method for Volume -Based, Constant Drawdown BMPs (See Appendix 11I.3.2) to determine the fraction of the DCV that must be provided to manage 80 percent of average annual runoff volume. This method accounts for drawdown time different than 48 hours. Step 1: Determine the drawdown time associated with the selected basin geometry DD = (dr / KDESIGN) x 12 in/ft Where: DD = time to completely drain infiltration basin ponding depth, hours dp= bioretention ponding depth, ft (should be less than or equal to 1.5 ft) Koesicr, = design media infiltration rate, in/hr (assume 2.5 inches per hour unless otherwise proposed) If drawdown is less than 3 hours, the drawdown time should be rounded to 3 hours or the Capture Efficiency Method for Flow -based BMPs (See Appendix 111.3.3) shall be used. Step 2: Determine the Required Adjusted DCV for this Drawdown Time Use the Capture Efficiency Method for Volume -Based, Constant Drawdown BMPs (See Appendix 111.3.2) to calculate the fraction of the DCV the basin must hold to achieve 80 percent capture of average annual stormwater runoff volume based on the basin drawdown time calculated above. Step 3: Determine the Basin Infiltrating Area Needed The required infiltrating area (i.e. the surface area of the top of the media layer) can be calculated using the following equation: A = Design Volume / dp Where. A = required infiltrating area, sq -ft (measured at the media surface) Design Volume = fraction of DCV, adjusted for drawdown, cu -ft (see Step 2) d„ = ponding depth of water stored in bioretention area, ft (from Step 1) This does not include the side slopes, access roads, etc. which would increase bioretention footprint. If the area required is greater than the selected basin area, adjust surface area or adjust ponding depth and recalculate required area until the required area is achieved. In South Orange County, the provided ponding plus pore volume must be checked to demonstrate that it is greater than 0.75 of the remaining DCV that this BMP is designed to address. See Section 111.7 and Worksheet SOC -1 uration for Use in a Treatment Train • Bioretention areas may be preceeded in a treatment train by HSCs in the drainage area, which would reduce the required design volume of the bioretention cell. For example. bioretention could be used to manage overflow from a cistern. a Bioretention areas can be used to provide pretreatment for underground infiltration systems.

Catch basin inserts are selected specifically based upon the orientation of hhe inlet and the expected sediment and debris loading. Opportunity Criteria • Catch basin inserts come in such a wide range of configurations that it is practically impossible to generalize the expected performance. Inserts should mainly be used for catching coarse sediments and floatable trash and are effective as pretreatment in combination with other types of structures that are reco nized as water unlit treatment v Drnh Inlet Filters Catch Basin Filters g q y BMPs. Trash and large objects can greatly reduce the effectiveness of catch basin inserts with respect to sediment and hydrocarbon capture. • Catch basin inserts are applicable for drainage area that include parking lots, vehicle maintenance areas, and roadways with catch basins that discharge directly to a receiving water. OC -Specific Design Criteria and Considerations ❑Frequent maintenance and the use of screens and grates to keep trash out may decrease the likelihood of clogging and prevent obstruction and bypass of incoming flows. ❑ Consult proprietors for specific criteria concerning the design of catch basin inserts. ❑ Catch basin inserts can be installed with specific media for pollutants of concern. Proprietary Manufacturer / Supplier Websites Table XIV.2 is a list of manufacturers that provide catch basin inserts.

Locations are provided below. 21-159 lean beaches WN and healthy creeks, rivers, bays, and ocean are important to Orange County. However, many common activities can lead to water pollution if you're not careful. Swimming pools and spas are common in Orange County, but they must be maintained properly to guarantee that chemicals aren't allowed to enter the street, where they can flow into the storm drains and then into the waterways. Unlike water in sanitary sewers (from sinks and,toilets), water in storm drains is not treated before entering our waterways. You would never dump pool chemicals into the ocean, so don't let it enter the storm drains. Follow these easy tips to help prevent water pollution. Help Prevent Ocean Pollution: Many pools are plumbed to allow the Pool to drain directly to the sanitary sewer. If yours is not, follow these: instructions for disposing of pool and Spit water. Acceptable and Pr- ferred Method of Disposal NAVhen you cannot dispose of pool water in the sanitary sewer, the release of dechlorinated swimming pool water is allowed if all of these Lips are followed: ®Tile residual chlorine does not exceed 0.1 rug/l (parts per million). MThe pH is between 6.5 and 8.5 ®The water is free of any unusual coloration, dill or algae. ®There is no discharge of filter media ®"I'lirre is no discharge of acid cleaning wastes. ® Some cities may have ordinances that do not allow pool water to be disposed into a storm drain. Check with your City. How to Know if You're Following the Standards You can find out how much chlorine is in your water by using a pool testing kit. Excess chlorine can be removed by discontinuing the use of chlorine for a few days prior to discharge or by purchasing dechlorinating chemicals from a local pool supply company. Always make sure to follow the instructions that come with any products you use. Doing Your Part By complying with these guidelines, you will make a significant contribution toward keeping pollutants out. of Orange County's creeks, streams, rivers, bays and the ocean. This helps to protect organisms that are sensitive to pool chemicals, and helps to maintain the health of our environment.

Siatc and Local Clean \Vater Act regulations and those of insurance carriers require Thal stommatcr filtration systems be maintained and seniced on it recurring basis, The intent of the regulations is to ensure that the systems, on a continuing basis. cffacicnily remove pollutants from stormwatcr nmoff (hereby preventing pollution of the nal ion's water resources. These Specificalions appy to the T-Scriesna Catch Basin hscrt Filter. RECOMMENDED FREQUENCY OF SERVICE: Drainage Protection Systems (DPS) recommends That installed T -Series''' Catch Basin Insert Filters be serviced on a recurring basis. Ultimately. the frequency depends on the amount of runoff. pollutant loading and interference front debris (lunges_ vegetation, ams. paper_ etc.); however, it is recommended that each installation be serviced a ntininunn of three times per year, with it change of filter medium once per year. DPS technicians are available to do an on-site evaluation. upon request. RECOMMENDED TIVIING OF SERVICE: DPS guidelines for the timing of service are as follows: 1. For areas evilly it definite rainy season: Prior to. dining and following lite ming season. 2. For ares subject to year-round rainfall: On it recurring basis (at lest three times per )ear). .. For areas with winter snow and summer rain: Prior to andjust after the snow wmson and during the summer rain season. 4. For installed devices not subject to alae elements (washr<acks, parking garages, cic.): On it recurring basis (no less dun three times per year). SERVICE PROCEDURES: 1. The sen -ice shall conuncnce with collection and removal of sediment and debris (litter, leaves. papers. ams. ete.) and broom sweeping around the drainage inlet. Accumulated materials shall be placed inn DOT approved container for later disposal. 2. The catch basin shall be visually inspected for defects and possible illegal dumping. If illegal dumping has occurred, the proper authorities and property owner representative shall be notified as soon as practicable. 3. The catch basin gruc shall be removed and set to one side. Using an industrial t acunm. lite collected naucrials shall be removed from the liner. (Note: DPS uses o tntck-mounted vacuum for servicing T-Serics''acalch basin inserts.) 4. When all of the collected materials have been removed, the filter medium pouches, if used. shall be removed by unstrapping lite Icther from the D -ring and sct to one side.

In addition, according to the Preliminary Utility Plan (Attachment 3), a new water service is proposed, to replace the existing service, with the assumption that the condition of the existing service is not satisfactory. The total proposed commercial building area will be 2,772 square feet. The area calculations for the proposed project are as follows: Main Level: 2"d Level: Commercial Area Commercial Area 1 54 sf 1 54 sf 2 1215 sf 2 1215 sf 3 117 sf 3 117 sf Total- 1,386 sf Total. 1,386 sf 3 21-176 Water Demand Memorandum 215 RIVERSIDE AVENUE NewportBeach, CA June 5, 2019 Water Demand Calculations The water demand for the existing site was estimated based the CC Appeal of PC Approval of Use Permit for Nesai Restaurant (see Attachment 4), along with Irvine Ranch Water District (IRWD) demand coefficients (see Attachment 2) for the existing development, which include the following: • First Floor Restaurant; 2,910 square feet (220 gal/ksf/day) = 640 gallons/day • Second Floor Office; 2,830 square feet (60 gal/ksf/day) = 170 gallons/day • Third Floor Office; 2,316 square feet (60 gal/ksf/day) = 139 gallons/day • Total Existing Water Demand = 949 gallons/day = 1.1 ac -ft per year The water demand for the proposed development is based on IRWD demand coefficient for commercial development. The IRWD value of 220 gallons/ksf/day was used, along with the total area calculation of 2,772 square feet. The water demand calculations are as follows: • 2,772 square feet (220 gal/ksf/day) = 610 gallons/day • Total Proposed Water Demand = 610 gallons/day = 0.7 ac -ft per year. Conclusion The water demand calculations show that the proposed project will require approximately 0.7 ac -ft of water per year. This will be a reduction from the existing water demand of 1.1 ac -ft per year. It is proposed to replace the existing service with a new water service line. The proposed new service location is shown on the Preliminary Utility Plan (Attachment 3). Attachments: I- Water Atlas Map G7 -W 2, IRWD Water Demand Factors 3.

Project Site Location The existing site is located in the City of Newport Beach, CA. The site is to the northwest of the intersection of Riverside Avenue and Avon Street. Existing Conditions The site area is 0.4 acre. Based on our review, the existing two-story building currently serves as office space, along with a restaurant. Based on our review of CC Appeal of PC Approval of Use Permit for Nesai Restaurant (see Attachment 1), the following is the usage of the existing site: • First -Floor Restaurant (107 seats) • Second Floor Office Space (2,830 square feet) • Third Floor Office Space (2,31 6 square feet) Based on our review of the City of Newport Beach GIS sewer atlas map (see Attachment 2), it appears that the existing wastewater is directed to an existing 6" City sewer line in Avon Street. From there, the line drains to the existing 8" sewer line in Riverside Avenue. The line continues southerly, and becomes a 12" diameter line at the southerly end of Riverside Avenue, and then connects to the existing Orange County Sanitation District (OCSD) sewer line in West Coast Highway (WCH). 21-188 Sewer Capacity Memorandum 215 RIVERSIDE AVENUE Newport Beach, CA June 5, 2019 Proposed Devefopmenf The proposed development includes demolition of the existing building, and construction of the new retail building. According to the Preliminary Utility Plan (see Attachment 4) the existing sewer lateral in Avon Street will be replaced with a new lateral cleanout. The total proposed commercial building area will be 2,772 square feet. The area calculations for the proposed project are as follows: Main Level: Commercial Area 1 54 sf 2 1215 sf 3 117 sf Total, 1,386 sf 2nd Level: Commercial Area 1 54 sf 2 1215 sf 3 117 sf Total. 1,386 sf 21-189 Sewer Capacity Memorandum 215 RIVERSIDE AVENUE NewportBeach, CA June 5, 2019 Sewer Generation Calculations (City of Los Angeles Sewer Factors) Since the City of Newport Beach does not have sewer generation factors for retail, commercial, or office uses (only residential), City of Los Angeles Sewer Factors were used. The calculations are based on the building square footage, along with a peaking factor. The following are the sewer calculations for both existing and proposed conditions: • Existing Condition o First Floor Restaurant; 107 seats x 30 gpd = 3,210 gpd o Second Floor Office; 2,830 square feet x 120/1000 gpd = 340 gpd o Third Floor Office; 2,316 square feet x 120/1000 gpd = 278 gpd ■ Total Average Daily Flow = (3,210+340+278) = 3,828 gpd ■ Peak Flow (peaking factor = 2.5): 9,570 gpd (0.0148 cfs) • Proposed Condition (commercial/retail): (50 gpd/1000 sf) x 2,772 square feet 0 139 gpd o Peak Flow (peaking factor = 2.5): 348 gpd (0.0006 cfs) A copy of the City of Los Angeles Sewerage Generation Factor Table is included as Attachment 2. Sewer Flow -Depth Calculations The flow -depth calculations of the peak flow were prepared using FlowMaster computer program. The flow -depth calculations shows an existing and proposed percent -full of 11 .2% and 2.5%, respectively. The calculations demonstrate that the proposed development will not adversely impact the existing sewer system, since the percent -full of the sewer system does not exceed 50% -full. In addition, the proposed sewer loading will be less than the existing condition loading. The calculations are included on the following pages. 3 21-190 Sewer Capacity Memorandum 215 RIVERSIDE AVENUE Newport Beach, CA June -5, 2019 Worksheet for Circular Pipe - Existing Development Project Description Friction Method Mannino Formula Salve For Normal Depth Input Data Roughness Coefficient 0.013 Channel Slope 0.01000 Wit Diameter 6 in Discharge 0.0148 ft'!s Results Normal Depth 0.06 it Flow Area 0.01 it, Wetted Perimeter 0.34 ft Hydraulic Radius 0.04 ft Top Width 0.32 it Critical Depth 0.06 ft Percent Full 11.2 ., Critical Slope 0.00814 ftift Velocity 123 ftls Velocity Head 0.02 ft Specific Enemy 0.06 it Froude Number 1.11 Maximum Discharge 0.60 fills Discharge Full 056 ft'ls Slope Full 0.00001 Rift Flour Type Super -Critical 4 21-191 Sewer Capacity Memorandum 215 RIVERSIDE AVENUE Newport Beach, CA June 5, 2019 Worksheet for Circular Pipe - Proposed Development Project Description Friction Maihod Manning Formula So We For Normal Depth Input Data Roughness Coefficient D.D13 Channel Slope 0.01 DDD Wit Diameter o in Discharge 0.0606 ft -,;s Results 14ormalDepth D.D1 ft Flo'viArca 0.00 fF 'Aletted Perimeter D.16 ft HydraulicPadius D.D1 ft TopL^ldlh 0.16 ft Critical Depth 0.01 ft Percent Full 2.5 % Critical Slope D.D1264 Wit Velocity 0.47 Ws Velocity Head 0.00 ft SpecificEneray 0.02 ft Froude Number 0.91 NlaximumDischaroe 0.60 f:,s Discharoe Full D.56 fNfs Slope Fuji 0.GDODG Puft FlowType SubCritical J 21-192 Sewer Capacity Memorandum 215 RIVERSIDE AVENUE Newport Beach, CA June 5, 2019 Conclusion The calculations presented in this memorandum show that the proposed 215 Riverside Avenue project will not adversely impact the existing sewer system.

(b) Bureau of Sanitation will determine the flow based on the information given by applicants for facilities with industrial discharge. The flow will be redetermined by Sanitation inspectors annually based on water bills. If the actual flow exceeds the previous year's determined flow, the applicants will be charged for the difference. If this type of facility is exempt from an industrial discharge permit, only the domestic SFC will be assessed. (c) The SFC for a bar shall be the sum of SFC's for all areas based on the SGF for each area (ex. fixed seat area, public table area, dancing area). (d) The determination of SGF for juice bars and coffee houses previously depended on the extent of the actual food preparation in house, not by the types of food provided. Food is assumed to be prepared offsite and as such, the three prior subcategories have been consolidated. 1) SGF for no pastry baking and no food preparation is 720 gpd/I000 gr.sq.ft. 2) SGF for pastry baking only and no food preparation is 720 gpd/1000 gr.sq.ft. 3) SGF for complete food preparation is 25 gpd/seat, the same as a fast food restaurant. Juice bars and coffee houses do not serve any alcoholic drinks. (e) Building construction includes trailers, field offices, etc. (f) Cocktail lounge usually does not serve prepared food. (g) Cold storage facilities are categorized as follow: 1) No Sales - the cold storage facility is used only for temporary storage, no selling is involved. For example, cold storage facilities at the harbor temporarily store seafood until it is distributed. 2) Cold storage w/ retail sales - the primary function of this facility is to support the wholesale/retail operation of a store, such as supermarket freezers, refrigerators, etc. (h) Counseling centers include marriage counseling centers. alcohol/drug rehabilitation /dependency centers, nutrition centers, diet centers, etc. 21-204 (i) Part-time basis schools or dance studios should be charged as retail area - 50 gpd /1000 gr.sq.ft. Full-time basis schools should be charged by the number of students. 0) Domestic waste is estimated at 50 gpd/1,000 square feet in addition to total process flow. (k) Bureau of Sanitation will determine if an industrial permit is needed for health spas. The first year flow is based on 650 gpd/1000 gr.sq.ft., and the Sanitation inspectors will redetermine the flow annually based on water bill from the previous year. The applicants are responsible for paying the difference of SFC. Health club/spa includes lobby area, workout floors, aerobic rooms, swimming pools, Jacuzzi, sauna, locker rooms, showers, and restrooms. if a health club/spa has a gymnasium type of facility, this portion should be charged separately at the gymnasium SFC rate. Gymnasiums include basketball court, volleyball court, and any other large open space with low occupancy density. (1) Lobby of retail includes lounges, holding rooms, or waiting area, etc. (m) Full service post offices include U.S. Postal Service, UPS, Federal Express, DHL, and etc. (n) The SGF for a college dormitory based on student capacity also includes the SGF for the dormitory cafeterias. (o) A bedroom is defined as an enclosed subdivision with 50 sq.ft. or more floor area in a residential building commonly used for sleeping purpose, and is partitioned off to form a habitable room. (p) The SGF for schools based on the student capacity, covers the following facilities: I ) classrooms and lecture halls 2) professors' offices 3) administration offices 4) laboratories for classes or research 5) libraries 6) bookstores 7) student/professor lounges 8) school cafeterias 9) warehouses and storage areas 10) auditoriums 11) gymnasiums 12) restrooms 21-205 It does not include water used by schools for swimming pools. When a school files an application for addition of any of the foregoing facilities, the student population will be reassessed and the total gpd for the new facility will be based on the number of students increased since the last SFC was paid or when the City implemented the SFC for the first time. The SFC for any school facility (ex. stadium, dormitory, etc.) not listed above, will be based on the designated SGF for that category. (q) The SFC for a TV or motion picture studio shall be the sum of SFC's for different facilities in the studio. based on the SGF for each facility. A studio may include one or more of the following facilities: audience viewing room, filming room, film processing, storage area, etc. (r) No independent tanning salons with shower were encountered during 1996 survey. (s) Alternative basis of charge for City's consideration. The prior square footage basis is also presented should the City decide to continue charging on that basis. 3 21-206 ATTACHMENT 4 Preliminary Utility Plan Sewer Capacity Memo - 215 Riverside Avenue Newport Beach, CA 21-207 ✓ CITY OF NEWPORT BEACH NOTES EASEMENT NOTES SCOPE OF WORK TOAL DEVELOPMENI SIATIS11CS NOTE 11) CONTRAG7011 I'll... > - ON STREET DETAIL 21-208 t 1P P- Lor D ON STREET DETAIL 21-208 Exhibit 5 Biological Resources Memorandum 21-209 TECHNICAL MEMORANDUM GLENN LUKOS ASSOCIATES Regulatory Services Pao.nEcr xt:ataER: 05600002RIVE TO: Greg Ramirez, Principal Planner, City of Newport Beach Makana Nova, Associate Planner. City of Newport Beach FROM: Tony Bomkamp DATE: September 23, 2019 SUBJECT: 215 Riverside Avenue, Newport Beach: Delineation and Evaluation of Wetland within Avon Street Right -of -Way West of Subject Property On September 3, 2019, I conducted a site visit to examine a potential wetland in the Avon Street right-of-way, west of the 215 Riverside Avenue project site (Exhibits 1 — Vicinity Map). During the site visit, I conducted a delineation of wetlands as defined in the City of Newport Beach Local Coastal Program (LCP) as well as in the California Coastal Act. I also evaluated the area to determine whether the area that is vegetated with predominately southern cattail (Tvpha dotningensis) meets the definition of a stream pursuant to Section 1602 of the Fish and Game Code. Finally, I evaluated the functions of the potential wetland area to determine the need for set backs or buffers in accordance with Section 21.30B.040.0 of the City's Local Coastal Program regarding Wetlands, Deepwater Areas, and Other Water Areas. Based on the presence of a predominance of wetland indicator plant species and wetland hydrology indicated by the presence of surface water I determined that a wetland is present along Avon Street. Wetland data sheets are provided as Appendix A. It is also important to note that during review of the City's files, additional information was found that documents the presence of wetlands at this location. Specifically, a letter from Dr. Jan Vandersloot dated April 19. 1989 detailing the results of a hvdrological studv of the area which indicates that the wetland is supported by a "spring" which drains toward the west, discharging to a culvert near the western terminus of the wetland, consistent with my observations. Dr. Vandersloot's letter is attached as Exhibit 5. A hand -drawing of the wetland area is also included as Exhibit 6. WETLANDS The richt-of-way for Avon Street supports a narrow strip of wetland dominated by southern cattail (Tvpha domingensis, OBL) with a few scattered arroyo willows (Salix lasiolepis. FACW) in the canopy laver with an understory of saltgrass (Dislichlis spicala. FAC). that is intertwined with the southern cattail. The extent of wetland area in the Avon Street right-of-way is depicted on Exhibit 29 Orchard Lake Forest California 92630-8300 Telephone: (949) 837-0404 Facsimile: (949) 837-5834 21-210 MEMORANDUM September 23, 2019 Page 2 2. The narrow strip of wetland area is bisected by two pedestrian bridges connected to sidewalks north of Avon Street. During the September 3, 2019 site visit, water from the wetland was detected discharging to a pipe at the west end of the wetland area beneath a dense thicket of giant reed (Arundo donax, FAC W), which appears to allow excess water in the wetland to drain. The wetland area is restricted on the south by the Avon Street curb and on the north by a steep slope, such that wetland area typically ranges from two to six feet in width. In order to evaluate the need for buffers, measurements were taken beginning approximately 100 feet from the 215 Riverside Avenue property. For the entire 100 -foot wetland segment nearest the 215 Riverside Avenue Property, the wetland is dominated by southern cattail with saltgrass understory and there are no arroyo willows within 100 feet of the 215 Riverside Avenue property. At the eastern pedestrian bridge, as depicted on Exhibit 3, the wetland vegetation transitions from mostly southern cattail to alkali bulrush (Schoenoplectus marilimus, OBL), which is the dominant wetland plant east of the pedestrian bridge. The area immediately east of the bridge exhibited surface water of one to two inches in depth, with surface water no longer present toward the eastern extent of the alkali bulrush. As depicted on Exhibit 3, the wetland ends abruptly where the vegetation changes to a monoculture of alkali heliotrope (Heliotropium currasavicum, FACU) (Exhibit 4, Photographs 1). The area dominated by alkali heliotrope, immediately east of the wetland was evaluated for hydric soils and subsurface water. Neither were detected confirming that the extent of alkali bulrush is the limit of the wetland on the east. SECTION 1602 NOTIFCIATION REQUIREMENTS In an email to the City dated August 23, 2019, Mr. Charles Klobe made the following assertion: On another note the adjacent riparian areas and stream of water are absolutely jurisdictional and the development of this site should be required to file a formal notification with the California Department of Fish and Wildlife to ensure that CDFW also concurs that there are no impacts from the proposed development. The site does not drain into this area however it is directly adjacent to the development and the CDFWS could at minimum require specific on-site protection to protect their stream. in my professional opinion, I do not believe that the wetland within the Avon Street right-of-way meeting the California Fish and Game Code for a "Stream"; rather, the feature is best characterized as a "Slope wetland''. Nevertheless, this is a moot point because, as discussed below, the wetland area is 29 feet from the closest area of impact and thus, there would be no Notification Requirements under Section 1602 as there is no potential alteration of a streambed or lake. 21-211 MEMORANDUM September 23, 2019 Page 3 WETLAND BUFFERS As noted. during the September 3, 2019 site visit, 1 evaluated the functions of the potential wetland area to determine the need for setbacks or buffers in accordance with Section 21.30B.040.0 of the Local Coastal Program, which states C. Wetland Bt fifers. A protective open space buffershall be required to horizontally .separate wetlands fi-om development areas. Welland buffers shall be of a sufficient size to ensure the biological integrity and preservation of the tivetland. Wetlands shall have a mininnon buffer width of one hundred (100)_feet wherever possible. 1. Exception: Smaller tivetlancl bakers may be allotived only where it can be demonstrated that: a. A one hundred (100) foot is;ide buffer is not possible due to site- specific constraints: and b. The proposed narrotiver buffer tivould be amply protective of the biological integrity of the Welland given the site -Specific characteristics of the resource and of the type and intensity of cli.sturbance. Existing Condition As described above, the wetland consists of a narrow strip (typically three- to six -foot -wide) immediately adjacent to the concrete curb along Avon Street. such that along the entire length of wetland, Avon Street is located approximately one to two feet from the wetland edge (see Exhibit 4, Photographs 2). The northern slope vegetated with mostly non-native species including overhanging Brazilian pepper trees (Schinus terebinthifolius), an invasive species.I giant reed. also an invasive species'- and non-native ornamentals such as plumbago (Plumbago capensis) and blue gum eucalyptus (Eucalyptus ;lobuhis), which line the majority of the slope. As depicted on Exhibit 3, the 215 Riverside Avenue site currently contains a vacant building with associated asphalt parking area. Immediately west of the parking area is a concrete wall that was constructed in a manner that encroaches on to City property and will be removed as a component of the project. As depicted on Exhibit 3, the existing retaining wall is located approximately 29 feet from the eastern -most extent of the wetland, which is approximately 39 feet west of the property line and the limit of development upon completion of the project. 21-212 MEMORANDUM September 23, 2019 Page 4 Purposes for Wetland Buffers Wetland buffers are often necessary to protect or ensure the integrity/functions of wetlands with high resource value. Wetland functions typically are separated into three areas for purpose of evaluating functions and associated impacts: Hydrologic, Biogeochemical (Water Quality), and Biological. Wetland buffers often are necessary to protect one or more of these functions from degradation. The purpose of this analysis is to evaluate the potential effects of the proposed project at 215 Riverside Avenue. Hyd rological/Hyd rology As noted above, the source of water detected in the wetland is from groundwater that ultimately drains to the western -most end of the wetland, discharging to a culvert approximately 430 feet from the eastern end of the wetland. Thus, the proposed project would have no potential to affect the hydrology of the wetland area, which is totally dependent on a groundwater source unconnected to the proposed project. Wetlands also provide certain functions such as surface water storage, groundwater discharge and support of aquatic plants and animals. The proposed project exhibits no potential for changing the ability of the narrow wetland area to store limited amounts of surface water or groundwater originating from the adjacent slope that discharges to the wetland area. The project would also have no effect on the hydrology such that changes to wetland species would be caused by the project. Other potential biological impacts are discussed below. Biogeochemical/Water Quality Buffers often protect wetlands from degradation of biogeochemical functions such as sediment inputs, discharge of pollutants originating from landscaped areas, discharge of pollutants as street runoff, or pollutants from other sources. Any potential impacts to water quality during construction would be fully addressed through project BMPs such as silt fence, straw wattle, and other necessary protections deten-nined in coordination with the City. In the post -project condition, the proposed project would have no potential to impact water quality. BiologicaUHabitat Functions As noted above, the cattail -dominated wetland is immediately adjacent to Avon Street, typically within a few feet of the street for its entire length as can be seen on Exhibit 4, Photographs 1 and 2. Thus, based on the existing conditions, as summarized above, the wetland exhibits very limited functions for wildlife, given the immediate surroundings, larger urban environment, very high "edge to habitat area" ratio, and the general low -value of cattails as habitat for special -status plants and animals. This is also the case for the area dominated by alkali bulrush east of the eastern 21-213 MEMORANDUM September 23, 2019 Page 5 pedestrian bridge, which has a much lower stature than the cattails (three feet for the bulrush and over ten feet for the cattails). Given the low -habitat value associated with the narrow strip of cattail and alkali bulrush, the proposed project at 215 Riverside Avenue would have no potential for indirect impacts on biological resources (as noted above, temporary grading would be approximately 29 feet from the eastern edge of the wetland) and in the final project, any potential development would be 39 feet from the wetland which is identical to the existing condition. Thus, in the final project configuration, there would be no development within 39 feet of the wetland, identical to the current conditions. The 39 -foot set back in the final configuration would provide more than adequate protection of the wetland, given that it is of low value and within one or two feet from Avon Street for the entire length. CONCLUSIONS The Avon Street Wetland is a slope wetland or groundwater fed wetland that has been documented at this location since at least 1989. The proposed development at 215 Riverside Avenue would have no potential to affect the wetland directly through dredging, filling, or other alteration. The proposed development would not affect the functions of the wetland which is located as close as two feet from Avon Street along its entire length, limiting the wetland functions. The proposed development has no potential to affect the wetland hydrology, which consists of discharging groundwater. The proposed project also exhibits no potential to affect biogeochemical (water quality) functions and would not affect potential habitat functions. Thus, the proposed development has not potential to adversely affect the Avon Street Wetland. 21-214 min M: Ns wrt lrNew . His PROJECT LOCATION fft. & A, Ind �-� z,.

Re: Avon Street Creekri r+tri;ceC.hief Dear Mayor Strauss, and City Council Members, � E]UU�er I wish to thank the City of Newport Beach for abandoning! the proposed parking lot along Avon Street, which would have destroyed the wetland along the street known as Avon Street Creek. However, there now appears to be another threat to this wetland which deserves your attention. Orange County Vector Control, apparently concerned about mosquitoes, has recently been asking the Public Works Department to clear out the vegetation in the wetland. It appears that there is presently not enough water in certain areas of the creek to support the mosquito fish which eat the mosquito larvae. In the past, the City has routinely removed vegetation in the creek with a backhoe, indiscriminately removing all. vegetation every year or so. Before authorizing this drastic step, however, I would like to request that the City hold off on the backhoe until our citizen's group, the Friends of Avon Street Creek, can meet and devise a plan to present to the City to protect and enhance the wetland vegetation, while restoring the water needed for the mosquito fish. The problem is basically twofold. One is that vegetation has grown to the point of crowding out the water, and needs to be thinned out. The other problem is that the recently completed storm drain under Avon Street is diverting ground water which normally would surface in the creek alongside the road, providing the water source for the creek. This diversion of water, approximately 22 gallons a minute of crystal clear fresh water, can be measured at the main rear entrance of the Newport Imports dealership at the manhole there. The water from the artesian springs uncovered by the construction of the storm drain is now largely being lost into the storm drain pipes, due to the leaky nature of the storm drains. The result is that before the storm drain construction, water flowed in the creek at the second set of stairs going up the west side of Cliff Drive Park at between 2 and 5 gallons a minute as measured by my geology consultants. After the storm drain, the soil is merely damp at this point, although thecmek flows at its normal rate of about 3 gallons a minute at the western terminus of the creek. Because of these changes, we would like to be given the opportunity to analyze alternatives designed to restore water to the creek. These alternatives range from elevating the drain pipes at the west end of 21-219 JAN U.

The springs will keep pumping water up to the level of drainage. If the drainage is blocked, flooding of the area occurs, which is what happened last Spring when a worker bulldozed over the drain pipe. The drain at the western end, if raised two feet, will raise the water level in the middle of the creek, where it is now needed). Water can also be restored into the creek by dredging down closer to the water table. Water can also be brought up from the water table by a pump, which might actually be cheaper to maintain than regular and repeated backhoe operations (the Environmental Nature Center also uses a pump to circulate water, although it has to purchase its water, while here it is free and available). In any case, a well thought out plan should be considered and analyzed, then implemented, rather than allowing precipitous and indiscriminate removal of vegetation as requested by Vector Control. I would like to request that the Public Works Department and the General Services Department not be authorized to remove the vegetation until our group can work with the City in devising an alternative plan. In addition, I would also recommend that since the Department of Fish and Game has determined that this area represents a wetland, and since this wetland lies within the Coastal Zone, that a Coastal Permit be applied for, before indiscriminate disruption of the flora and fauna in the creek. In this same regard, and since the status of this area as a wetland is disputed by some of the City's staff, I would like to request that the City initiate the proper procedures to determine once and for all that this area is indeed a wetland, so that in the future, this wetland will receive the normal official protections that heretofore have been lacking. Thank you. Attached: Register news article 3100T // Sincerely, Jan D. Vandersloot MD 21-220 613C Wednesday, March 2 - Thursday, larch 3, 1988 The Orange County Hegislor 3 Environmentalists, Juaneno Indians fight parking -lot plan Newport would hurt wetlands, historic pitch mine, they say By Roberta Landman i ho Aegisrer NEWPORT BEACH — A 40- space aspace parking lot for an unim- proved section of Avon Street is raising the hackles of Newport Beach environmentalists and an Indian tribe.

And sourewhere within the near- by earby cliff is the site of a long -hidden Indian pitch mine, they said.

His sentiments are shared by Jan Vandersloot, leader of a pro - lest group that has named itself Friends of the Avon Street Wet- lands. Vandersloot, a Newport Heights resident, has commissioned b}olog- leal and geological assessments of the Avon Street area and cliff site. The results of a study by biological consultant Karlin Marsh confirm Vanderaloot's notion that the area, though small, is a natural wetlands area — a remaining piece of hlstar- ic wetletlds once extensive In the Newport Beach area. "The (freshwater) wetland is small, flat it's nice, and quite un- usual in something as intensely de- veloped an area as Newport Heights," Marsh said. "It's a reminder of what used to be. ... file last of its kind. That makes it special." "It has a good assortment of plants and animals within the en- vironment ... aquatic insects - butterflies nectaring on flowers — the watercress is coming into bloom..., it's functioning as a for- aging source and a source of water of animals laid birds," Marsh said. "I'm not a hydrologist," Marsh said, "but I observed what ap- panted to be spring -fed seepage einto that tittle creek, movement from where it spring seemed to be entering it." Wherever that writer comes from, Marsh sold, "It's not surface runoff." City officials in the Planning and Public Works departments think otherwise. Theysay the water comes from urban runoff -- the, residue of watering lawns in New- port heights mixed with a high wa. ter table. The city also received contrary biological information from a study it commissioned. That re- port, by Kellen Swirsky of Michael Brandmmr Associates, found stag- nant water intend of moving wa- ter on the Avon Street waterway and said the t real did nor represent a significant biological resource. One report, however, did estub- Iish the area as a wetland habitat, but It diminished it in hnportance.

There appear to be no significant geotechnical constraints on-site that cannot be mitigated by proper planning, design, and utilization of sound construction practices. The engineering properties of the soil and native materials, and surface drainage offer favorable conditions for site re -development. The following key elements are conclusions confirmed from this investigation: A review of available geologic records indicates that no active faults cross the subject property. The site is located in the seismically active Southern California area, and within 2 kilometers of the Type B Newport -Inglewood Fault. As such, the proposed development shall be designed in accordance with seismic considerations specified in the 2016 California Building Code (CBC) and the City of Newport Beach requirements, Foundation specifications herein include added provisions for potential liquefaction on-site per City policy CBC 1803.11-12.

The purpose of our investigation was to evaluate the existing geotechnical conditions at the subject site and provide recommendations and geotechnical parameters for site re- development, earthwork, and foundation design for the proposed re -construction. We were also requested to evaluate the potential for on-site geotechnical hazards. This report presents the results of our findings, as well as our conclusions and recommendations. SCOPE OF STUDY The scope of our investigation included the following tasks: • Review of readily available published and unpublished reports; • Geologic reconnaissance and mapping; • Excavation and sampling of three (3) exploratory boring to a total depth of 17 feet below existing grade (b.g.); • Advancement of four (4) continuous Cone Penetration Test (CPT) soundings to a maximum depth of 50 feet below grade (results of the CPT soundings are included herein); • Laboratory testing of representative samples obtained from the exploratory borings; • Engineering and geologic analysis including seismicity coefficients in accordance with the 2016 California Building Code (CBC); • Seismic and Liquefaction analysis and settlement computations (in accordance with California Geological Survey, SP 117A); 21-241 • Preparation of this report presenting our findings, conclusions, and recommendations. GENERAL SITE CONDITIONS The subject property is a semi -rectangular shaped parcel located at 215 Riverside Avenue in the City of Newport Beach, County of Orange, California (see Site Location Map, Figure 1). The lot dimensions are provided on Plot Plan, Figure, 2, with approximate lot area of 19,000 square feet. For the purpose of clarity in this report, the lot is bound by Avon Street to the south, by Riverside Avenue to the east, by residential homes to the north, and by Cliff Drive Park to the west. The nearest cross street is Avon Street. The lot is located on the mainland side of Pacific Coast Highway. Channel waters of the Newport Bay are approximately 850 feet to the south, and the Pacific Ocean is located approximately 4,354 feet southwest of the site (see Site Location Map, Figure 1), The subject property consists of a relatively flat, terraced lot with a gradual 2.5:1 slope in the north of the property, up to the adjacent residential homes. Currently, the lot is occupied by a office -retail business situated on a graded level pad. All structures are supported on continuous perimeter footings with slab -on -grade floors (see Plot Plan, Figure 2). The site is legally described as Parcels D and 3 of PMB 237135-36, in the City of Newport Beach, County of Orange, California (APN 049-103-17). PROPOSED COMMERCIAL -OFFICE USE RE -DEVELOPMENT The precise grading plan is not available at this time. However, based on our review of the preliminary plans by Laidlaw Schultz Architects, the proposed scope of work includes the demolition of the existing structures, and the construction of a two-story 2,500 sq. ft. commercial office building and a 50 -space parking area with associated improvements and retaining walls. We assume that the proposed buildings will consist of wood -frame and masonry block construction or building materials of similar type and load. The building foundations will consist of a combination of isolated and continuous spread footings. Loads on the footings are unknown, but are expected to be less than 2,500 and 2,000 pounds per square foot on the isolated and continuous footings, respectively. if actual loads exceed these assumed values, we should be contacted to evaluate whether revisions of this report are necessary. It is our understanding that the grade of the sites are not expected to vary significantly, with maximum regrades consisting of approximately 1 to Proposed 2 -Story Commeroial Orfice Qevelopmcni 215 Riverside Avenue, Newport Beach, CA Snits Kc Pon Project No. SLI48.1 November 5, 2018 i 21-242 2 feet in the building areas. Based on NAVD88, the lowest site elevation is approximately 17 feet above MSL. Based on the preliminary plans, the proposed finish floor elevation shall be 9-+ ft. above mean sea level (MSL) to conform with City and United Stakes FEMA flood elevation requirements. Note: The precise determination, measuring, and documenting of the site elevations, hub locations, property boundaries, etc., is the responsibility of the project licensed land surveyor. SUBSURFACE EXPLORATION Our subsurface exploration consisted of the excavation of three (3) exploratory boring (B-1, B-2, and B-3) to a maximum depth of 17 feet below grade (b.g.) and four (4) CPT probes (CPT -1, GPT -2, CPT -3, and CPT -4) to a depth of 50 ft. b.g. (continuous soil profile). Prior to drilling, the underground detection and markup service (Underground Service Alert of Southern California) was ordered and completed under ❑igAlert Confirmation No. A182531182 -ODA, Representative bulk and relatively undisturbed soil samples were obtained for labora- tory testing. Geologic/CPT logs of the soil boring/probes are included in Appendix A. The borings were continuously logged by a registered geologist from our firm who obtained soil samples for geotechnical laboratory analysis. The approximate locations of the borings are shown on Figure 2, Plot Pian. Geotechnical soil samples were obtained using a modified California sampler filled with 23/a inch diameter, 1 -inch tall brass rings. Bulk samples were obtained by collecting representative bore hole cuttings. Locations of geotechnical samples and other data are presented on the boring logs in Appendix A. The soils were visually classified according to the Unified Soil Classification System. Classifications are shown on the boring logs included in Appendix A. LABORATORY TESTING Laboratory testing was performed on representative soil samples obtained during our subsurface exploration.

Geotechnical test results are included in Appendix B, herein. SOIL AND GEOLOGIC CONDITIONS The site soil and geologic conditions are as follows: eer)aae and Groundwater Seepage or surface water ponding was not noted on the subject site at the time of our study. Groundwater was not encountered in our test excavations. According to the Orange County Water District (OCWD), there are no water wells located within the general vicinity of the subject property. Our data indicates,that perched groundwater subject to tidal fluctuations is encountered in the region, but was not present on site at the time of our test excavations. Channel waters of the Newport Bay are approximately 850 feet to the south, and the Pacific Ocean is located approximately 4,350 feet southwest of the site (see Site Location Map, Figure 1). A tidal chart during the week of September 28, 2018, presented as Figure 4, herein. Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5, 2018 21-244 Geologic Setting Regionally, the site is located within the western boundary of the Coastal Plain of Orange County. The Coastal Plain lies within the southwest portion of the Los Angeles Basin and consists of semi -consolidated marine and non -marine deposits ranging in age from Miocene to recent. The western boundary of the Coastal Plain, in which the site is located, is referred to as the Tustin Plain. It is bound by the Santa Ana Mountains to the northeast and the San Joaquin Hills to the southeast. Based on available geologic maps the site is underlain by a thin mantle of residual soils and/or engineered fill. The shallow soil layer is underlain by older terrace deposits (Qtm) which are described as silty sands and with trace clays (see reference No. 2). The competent terrace deposits are underlain by bedrock of the Monterey Formation (Tm). Roadside exposures of massive bedrock of the Monterey Formation (Tm) are visible on the inland side of the Pacific Coast Highway less than'/2 kilometers northwest and southeast of the site (Banning Ranch and Dover Shores bluffs). A Geologic Map is presented as Figure 3, herein (reference: Morton, D.M., and Miller, F.K., 2006). Faulting A review of available geologic records indicates that no active faults cross the subject property (Figure No. 3 and reference No. 2). Seismicity The seismic hazards most likely to impact the subject site is ground shaking following a large earthquake on the Newport -Inglewood (onshore), Palos Verdes (offshore), Whittier -Elsinore, or Cucamonga. The fault distances, probable magnitudes, and horizontal accelerations are listed as follows: FAULT DISTANCE FROM MAXIMUM CREDIBLE MAXIMUM (Seismic SUBJECT SITE EARTHQUAKE HORIZONTAL Source Type) (Kilometers) MAGNITUDE ROCK ACCELERATION Newport- 2 kilometers southwest 7.2 0.69 g's Inglewood (B) Palos Verdes 16 kilometers 7.1 0.38 g's (B) southwest Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5. 2018 21-245 Chino -Cental 40 kilometers northeast 6.7 0.14 g's Avenue (B) D Mapped Spectral Response Acceleration at 0,2s Period, Ss 1.700 g Elsinore (B) 37 kilometers northeast 6.8 0.16 g's Cucamonga 50 kilometers north- 7.0 0.14 g's (A) northeast The maximum anticipated bedrock acceleration on the site is estimated to be less than 0.69, based on a maximum probable earthquake on the Newport - Inglewood Fault. The site is underlain by fill and estuarine sands. For design purposes, two-thirds of the maximum anticipated bedrock acceleration may be assumed for the repeatable ground acceleration. The effects of seismic shaking can be mitigated by adhering to the 2016 California Building Code or the standards of care established by the Structural Engineers Association of California. With respect to this hazard, the site is comparable to others in this general area in similar geologic settings. The grading specifications and guidelines outlined in Appendix C of the referenced report are in part, intended to mitigate seismic shaking. These guidelines conform to the industry standard of care and from a geotechnical standpoint, no additional measures are warranted. Based on our review of the "Seismic Zone Map," published by the California Department of Mines and Geology in conjunction with Special Publication 117, there are no earthquake landslide zones on or adjacent to the site. The proposed development shall be designed in accordance with seismic considerations contained in the 2016 CBC and the City of Newport Beach requirements. Based on Chapter 16 of the 2016 CBC and on Maps of Known Active Near - Source Zones in California and Adjacent Portions of Nevada (ASCE 7 Standard), the following parameters may be considered: 2016 CBC Seismic Design Parameters SITE ADDRESS: 215 Riverside Avenue, Newport Beach, CA Site Latitude (Decimal Degrees) 33.6219 Site Longitude (Decimal Degrees) -117.92365 Site Class Definition D Mapped Spectral Response Acceleration at 0,2s Period, Ss 1.700 g Mapped Spectral Response Acceleration at is Period, Si 0.627 g Short Period Site Coefficient at 0.2 Period, Fa 1.00 Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL 14 8. 1 November 5, 2018 21-246 Long Period Site Coefficient at is Period, Fv 1.50 Adjusted Spectral Response Acceleration at 0.2s Period, S,,rs 1.700 g Adjusted Spectral Response Acceleration at is Period, S,, 0.941 g Design Spectral Response Acceleration at 0.2s Period, Sps 1.133 g Design Spectral Response Acceleration at Is Period Soi 0.627 g In accordance with the USGS Design Maps, and assuming Site Class "D", the mean peak ground acceleration (PGAm) per USGS is 0.696 g. The stated PGAm is based on a 2% probability of exceedance in a 50 year span (see copies of the USGS Design Maps Detailed Report, Appendix D, herein). Other Geologic Hazards Other geologic hazards such as landsliding, or expansive soils, do not appear to be evident at the subject site. FINDINGS Subsurface Soils As encountered in our test borings, the site is underlain by, fill and native materials as follows: Fill A Fill soils were encountered in a depth of approximately 2% to 3 feet b.g, The fill soils consist generally of grayish brown, dry to damp, loose to medium dense, silty sand with clay and gravel. The expansion potential of the fill soils was tested (in accordance with ASTM D 4829) and is determined to be non -expansive (E.I. = 0) when exposed to an increase in moisture content. Based on the laboratory results dated October 16, 2018, the site maximum dry density is 119.0 pcf at an optimum moisture content of 10.5 % (per ASTM D 1557). The sulfate content of the on site soils were determined to be negligible, Class [SO]. The complete laboratory reports are presented in Appendix B, herein. Native - Terrace Deposits (Qtm) Underlying the fill materials are Quaternary -age terrace deposits as encountered in each of the test borings (B-1 through B-3 and CPT -1 Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No, SL148.1 November 5, 2018 21-247 through CPT -4) to the maximum depths explored (17 ft b.g.). The native soils consist generally of gray brown, dry to moist, medium dense, non- cemented, fine- to medium -grained, micaceous sand with silt layers which becomes less weathered with depth. Monterev Formation (Tm Though not encountered in any of the three hand-augered test borings, the terrace deposits on the subject site are underlain by deposits of the Miocene age Monterey Formation. Bedrock exposures are visible in the rear yard and park of the natural slopes ascending to Cliff Drive, This correlates with the high blow count data from our CPT probe advanced on October 26, 2018 (see continuous log in Appendix A, herein). Bedrock materials consist generally of marine siltstone and sandstone, siliceous and diatomaceous, and dense to very dense. The bedrock is moderately weathered becoming less weathered with depth. Based on the extrapolation of data and geologic maps (Figure 3 of the soils report), the geologic structure of the bedrock (bedding) dips at gentle angles (horizontal to 10 degrees) to the north and west. This structural orientation is considered to be neutral to favorable with respect to the gross stability of the rear and surrounding slopes underlain with bedrock. LIQUEFACTION ANALYSIS Per SP1 17A) Liquefaction of soils can be caused by strong vibratory motion in response to earthquakes. Both research and historical data indicate that loose, granular sandy soils are susceptible to liquefaction, while the stability of rock, gravels, clays, and silts are not significantly affected by vibratory motion. Liquefaction is generally known to occur only in saturated or near saturated granular soils. The site is underlain by fill/estuarine sands, old paralic deposits, and bedrock of the Monterey Formation. It is our understanding that the current City policy, has assigned a seismic settlement potential of one (1.0) inch in the upper ten feet, and three (3.0) inches for soil depths of ten to fifty feet. In the event settlement values exceed these threshold values, then additional analysis and/or additional mitigation is required. The CPT testing was performed in accordance with the "Standard Test Method for Performing Electronic Friction Cone and Piezocone Penetration Testing of Soils," (ASTM D5778-12). The seismically induced settlement for the proposed structure was evaluated based on the "Soil Liquefaction During Earthquakes" by Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL 148.1 November 5, 2018 9 21-248 I.M. ldriss and R.W. Boulanger, dated September 8, 2048. The analysis was provided by the 10 -feet deep 4 " diameter hand -auger borings, and a 50+ feet deep 1.7" diameter CPT probe advanced on October 26, 2018. The exploratory boring and probe locations are shown in the Plot Plan, Figure 2, herein. The soil borings were continuously logged by a certified engineering geologist of our firm. The computations and results of our Liquefaction Analysis, based on CPT blow counts of Boring CPT -1 are attached in Appendix E, herein. The seismically induced settlement analysis was evaluated based on methods published in the references Nos. "a" through "j" (see "Associated References", herein), The liquefaction and seismic settlement calculations indicate seismic settlement (includes dry and saturated sands) in the upper 50 feet is less than 2.0 inches and less than 1.0 inch in the upper 10 feet. Hence, shallow mitigation methods for liquefaction may be implemented per City Code Policy (No. CBC 1803.5.11- 2 last revised 71312014). Based on our liquefaction analysis, and in accordance with the City of Newport Beach Policy No. CBC "803.5.91-12 (NBMC, Charter 15), we recommend the following mitigative methods to minimize the effects of shallow liquefaction: 1. Tie all pad footings with grade beams. 2. All footings should be a minimum of 24 inches deep, below grade. 3. Continuous footings should be reinforced with two No. 5 rebar (two at the top and two at the bottom). 4. Concrete slabs cast against properly compacted fill materials shall be a minimum of 5 inches thick (actual) and reinforced with No. 4 rebar at 12 inches on center in both directions. The reinforcement shall be supported on chairs to insure positioning of the reinforcement at mid -center in the slab. 5. Dowel all footings to slabs with No. 4 /oars at 24 inches on center. The foundation specifications outlined above will act to decrease the potential settlement due to liquefaction and/or seismically induced lateral deformation to tolerable amounts. If the above specifications are incorporated, the proposed structure shall be stable and adequate for the intended uses and the proposed construction will not adversely impact the subject or adjacent properties.

CONCLUSIONS Based on our geotechnical study of the site, our review of available reports and literature and our experience, it is our opinion that the proposed improvements at the site are feasible from a geotechnical standpoint. There appear to be no significant geotechnical constraints on-site that cannot be mitigated by proper planning, design, and utilization of sound construction practices. The engineering properties of the soil and native materials, and the surface drainage offer favorable conditions for site re- development. RECOMMENDATIONS The following sections discuss the principle geotechnical concerns which should be considered for proper site re -development. Earthwork Grading and earthwork should be performed in accordance with the following recommendations and the General Earthwork and Grading Guidelines included in Appendix C. It is our understanding that the majority of grading will be limited to the re -grading of the building pad for the proposed construction. In general, it is anticipated that the removal of the upper 3 feet within the building footprint (slab -on -grade portion) will require removal and recompaction to prepare the site for construction. The removals should be accomplished so that all fill and backfill existing as part of the previous site use and demolition operations are removed. Where feasible, the limits of the pad fill shall be defined by a five (5) feet envelope encompassing the building footprint. Care should be taken to protect the adjacent property improvements. A minimum one foot thick fill blanket should be placed throughout the exterior improvements (approaches, hardscape, etc.). The fill blanket will be achieved by re -working (scarifying) the upper 12 inches of the existing grade. Water via a 2 -inch hose shall be vigorously induced during the pad grading operations. Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5, 2018 11 21-250 Site Preparation Prior to earthwork or construction operations, the site should be cleared of surface structures and subsurface obstructions and stripped of any vegetation in the areas proposed for development. Removed vegetation and debris should then be disposed of off-site. A minimum of 3 feet of the soils below existing grade will require removal and recompaction in the areas to receive building pad fill. Following removal, the excavated surface should be inspected by the soils engineer or his designated representative prior to the placement of any fill in footing trenches. Holes or pockets of undocumented fill resulting from removal of buried obstructions discovered during this inspection should be filled with suitable compacted fill. Fills The on-site soils are suitable for reuse as compacted fill, provided they are free of organic materials, debris, and materials larger than six (6) inches in diameter. After removal of any loose, compressible soils, all areas to receive fill and/or other surface improvements should be scarified to a minimum depth of 12 inches, brought to at least 2 percent over optimum moisture conditions and compacted to at least 90 percent relative compaction (based on ASTM: D 1557). If necessary, import soils for near -surface fills should be predominately granular, possess a very low expansion potential, and be approved by the geotechnical engineer. Lift thicknesses will be dependent on the size and type of equipment used. In general, fill should be placed in uniform lifts not exceeding 8 inches. Placement and compaction of fill should be in accordance with local grading ordinances under the observation and testing of the geotechnical consultant. We recommend that fill soils be placed at moisture contents at least 2 percent over optimum (based on ASTM: D 1557). We recommend that oversize materials (materials over 6 inches) should they be encountered, be stockpiled and removed from the site. Trench Backfill The on-site soils may be used as trench backfill provided they are screened of rock sizes over 6 inches in dimension and organic matter. Trench backfill should be compacted in uniform lifts (not exceeding 8 inches in compacted thickness) by mechanical means to at least 90 percent relative compaction (ASTM: D 1557). Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5, 2018 12 21-251 Geotechnical Parameters The following Geotechnical parameters may used in the design of the proposed structure (also, see "Liquefaction Analysis" section, above): Foundation Design Structures on properly compacted fill may be supported by conventional, continuous or isolated spread footings. All footings should be a minimum of 24 inches deep (measured in the field below lowest adjacent grade). Footing widths shall me an minimum 15 inches for interior cross beams and 18 inches for perimeter footings. As stated above, additionally, to further reduce the effects of the thin zones of potentially liquefiable soils, the building slab shall include 15" wide by 24" deep interior grade beams to be reinforced with two No. 5 rebars (two at the top and two at the bottom). The cross beam locations shall be determined by the structural engineer. At this depth (24 inches) footings founded in fill materials may be designed for an allowable bearing value of 2,400 and 2,500 psf (for dead -plus -live load) for continuous wall and isolated spread footings, respectively. These values may be increased by one-third for loads of short duration, including wind or seismic forces. Reinforcement requirements may be increased if recommended by the project structural engineer. In no case should they be decreased from the previous recommendations. Mat Foundation Design jOptioriaO Due to anticipated high tide waters and cohesionless sands during construction, a mat slab foundation system is a recommended option. Mat slabs founded in compacted fill or competent native materials may be designed for an allowable bearing value of 2,500 psf (tor dead -plus -live load). These values may be increased by one-third for loads of short duration, including wind or seismic forces. The actual design of the foundation and slabs should be completed by the structural engineer.

The slabs shall be doweled into the footings using No. 4 bars at 24 inches on center. The reinforcement shall be supported on chairs to insure positioning of the reinforcement at mid -center in the slab. Interior slabs shall be underlain by 2 inches of clean sand over a min. 15 mil thick, puncture -resistant plastic sheeting (e.g. "Stego Wrap"), with all taps sealed, over 4 inches of 3/ -inch gravel (see "Capillary Break" specifications, below). Some slab cracking due to shrinkage should be anticipated. The potential for the slab cracking may be reduced by careful control of water/cement ratios. The contractor should take appropriate curing precautions during the pouring of concrete in hot weather to minimize cracking of slabs. We recommend that a slipsheet (or equivalent) be utilized if crack -sensitive flooring is planned directly on concrete slabs. All slabs should be designed in accordance with structural considerations. Cement Type for Concrete in Contact with On -Site Earth Materials Concrete mix design should be based on sulfate testing with Section 1904.2 of the 2016 CBC. preliminary laboratory testing indicates the site soils possess negligible sulfate exposure. In the event import soils are used, the soils shall be tested for sulfate content and the associated recommendation shall be implemented as follows.

Settlement Utilizing the design recommendations presented herein, we anticipate that the majority of any post -grading settlement will occur during construction activities. We estimate that the total settlement for the proposed structure will be on the order of 1 inch. Differential settlement is not expected to exceed 1 inch in 30 feet. These settlement values are expected to be within tolerable limits for properly designed and constructed foundations. Lateral Load Resistance Footings founded in fill materials may be designed for a passive lateral bearing pressure of 250 pounds per square foot per foot of depth. A coefficient of friction against sliding between concrete and soil of 0.30 may be assumed. Capillary Break Below Interior Slabs In accordance with the 2016 California Green Building Standards Code Section 4.505.2.1, we provide the following building specification for the subject site (living area and garages slabs): Concrete building slabs shall be directly underlain by a min. 2 inches of clean/washed sand, underlain by a min. 15 mil -thick moisture barrier (e.g. "Stego Wrap"), with all laps sealed, underlain by 4 inches of 3/ -inch gravel. The above specification meets or exceeds the Section 4.505.2.1 requirement. We do not advise placing sand directly on the gravel layer as this would reverse the effects of vapor retardation (due to siltation of fines). A/C Pavement Subbase Asphaltic concrete (AC) and Class II rock base should conform to, and be placed in accordance with the latest revision of the California Department of Transportation Standard Specifications. We assume that Class II base with a minimum R -value of 78 will be used; as follows: Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5, 2018 15 21-254 RECOMMENDED MINIMUM DESIGN SECTIONS LOCATION DESIGN TRAFFIC ASPHALTIC CLASS II INDEX CONCRETE AGGREGATE BASE Car Traffic, Parking 4.0-5.0 3.5" 4,01- .0"Areas Areas Heavy Truck Traffic 5.0-6.0 4.5" 6.0" Aisles Trash Pads 5.0-6.0 6.0" (Concrete) 6.0" Truck Dock or 5.0-6.0 6.0" (Concrete) 6.0" Truck Pads The minimum section of 6 inches concrete over 6 inches Class 11 Base Material applies to the site approaches. If off-site (surrounding roadways) work is anticipated, the Minimum Design Section shall conform with either the County or Caltrans specifications, depending on jurisdiction. Prior to placing pavement sections, the subbase soil should have a relative compaction of at least 90 percent, based on ASTM: D 1557. We also recommend that the base course be compacted to a minimum of 95 percent relative compaction (based on ASTM: D 1557-13). If pavement areas are planned adjacent to landscaped areas, we recommend that the amount of irrigation be kept to a minimum to reduce the possible adverse effects of water on pavement subgrade. Retaining Wall Design Since the grading plan is not yet available, the limits of the retaining walls are not known at this time. However, based on the preliminary architectural renderings, all retaining and landscape wall footings will be embedded into competent native materials. The following equivalent fluid pressures may be used in the design of the site retaining walls assuming free draining conditions (select granular backfill): Equivalent Fluid Pressure Condition Level Active Pressures 40 pcf At -Rest Pressures 55 pcf For the soldier pile caisson locations along confined areas (side yards and slopes), the following recommended equivalent fluid pressures may be used in the site retaining wall design assuming backfill using on-site soils (based on triangular distribution): Propused 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5. 2018 16 21-255 Equivalent Fluid Pressure Condition Level Active Pressures 65 pcf At -Rest Pressures 90 pcf Depending on whether the wall is restrained (rigid) or unrestrained (free to deflect), an additional uniform lateral pressure equal to 50 or 33 percent, respectively, of the anticipated maximum surcharge load located within a distance equal to the height of the wall should be used in design. This office shall be contacted to provide additional recommendations if actual conditions are different than those assumed above. Lateral Pressure - New Retaining Walls founded in competent native materials A passive earth pressure of 300 pounds per square foot per foot of depth, to a maximum value of 3,000 pounds per square foot, may be used to determine lateral bearing resistance for footings founded in terrace deposits or bedrock. A coefficient of friction of 0.30 times the dead load forces may be used between concrete and the supporting soils to determine lateral sliding resistance. However, the lateral sliding resistance should not exceed one-half the dead load. An increase of one-third of the above values may also be used when designing for short duration wind and seismic forces. The above lateral resistance values are based on footing placed directly against competent native materials. In cases where footing sides are formed, all backfill placed against the footings should be compacted to at least 90 percent of the applicable maximum dry density value. Passive pressure is used to compute lateral soil resistance developed against lateral soil movement. Further, for sliding resistance, a friction coefficient of 0.30 may be used at the concrete and soil interface. These lateral and frictional resistance values represent ultimate values, so appropriate safety factors for wall design should be applied by the structural engineer. Settlement Utilizing the design recommendations presented herein, the total settlement of the building slabs/foundations is expected to be less than 1 inch. The differential settlement between adjacent footings is expected to be less than 1/4 inch over a horizontal span of 40 feet. It is anticipated that the majority of the footing settlements will occur during construction or shortly thereafter as building loads are applied. Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5, 2018 17 21-256 Retaininci Wall Backfill Material It is recommended that a minimum 2 -foot thick layer of free -draining granular material Mess than 5 % passing the No. 200 sieve) be placed against the back face of the retaining walls. This material should be approved by the geotechnical engineer. This layer of granular material should be separated from the adjacent soils using a suitable geotextile fabric. If the layer of free -draining material is not covered by an impermeable surface, such as a structure or pavement, a 12 -inch thick layer of a low permeability soil should be placed over the backfill to reduce surface water migration to the underlying soils. All retaining wall backfill should be placed and compacted under engineering controlled conditions in the necessary layer thickness to ensure a minimum in- place density of 90 percent of the maximum dry density as determined by the Modified Proctor test (ASTM D1557), Care should be taken to avoid over - compaction of the soils behind the retaining walls, and the use of heavy compaction equipment should be avoided. Retaining Wall Back Drains The retaining walls shall be provided with water proofing in accordance with the architects recommendations and be free draining. Back drains shall be installed to collect and divert migrating groundwater. As a minimum, the wall may be drained by placing a 4 -inch diameter pipe perforated (faced down) PVC Schedule 40 pipe or approved equivalent, located behind the base of the wall. The pipe shall be covered by %-inch crushed rock at a rate of not less than 2 sq. ft. per linear ft, of pipe surrounded in turn by geofabric such as Supac 4NP or equivalent. All wall backfili shalt be compacted to a minimum 90 percent relative compaction in accordance with ASTM D-1557. Wail back drains shall outlet separately and not be combined with area drains. This office shall be contacted to provide additional recommendations if actual conditions are different than those assumed above. During construction, drainage devices shall be inspected by a representative of EGA Consultants. SHORING INSTALLATION RECOMMENDATIONS Since the grading plan is not yet available, the limits of the retaining walls and associate shoring are not known at this time. However, based on our review of preliminary architectural renderings, we understand that permanent andlor temporary shoring is proposed along portions of the each side yard and the base of the ascending slope at the rear of the property. The approximate limits of the recommended caisson layout shall be presented when the building footprints and retaining walls have been Proposed 2 -Story Currunercial Uffice Denloprnent 215 Riverside Avenue, Ncwport Brash, CA Suits Report Project No SL149.1 November 5, 2018 1.8 21-257 determined. It is our understanding that the shoring will be designed having a combination of temporary and permanent shoring segments, based on the project locations and proposed elements. It is our understanding that the shoring system will consist of steel "H" beam soldier piles and either wood or steel sheet lagging. The steel "H" beam soldier piles should be installed within pre -drilled holes. The soldier piles should not be driven or vibrated into place due to the possible damage that could occur to nearby structures. Once a soldier pile boring is advanced to its recommended depth, a steel soldier pile should be place within the boring and the boring then backfilled. The borings should be backfilled with concrete up to the elevation of the excavation bottom. Above the excavation bottom, the borings may be filled with 2 -sack slurry. Due to the anticipated moderate exposure to sulfates, Type II cement should be used in the concrete. In addition, the maximum water -cement ratio should not exceed 0.50 and the minimum concrete compressive strength should not be less than 3,000 pounds per square inch. The drill holes for the steel "H" piles should be sufficiently large to allow concrete backfilling around piles to be performed as effectively as possible. Any voids left between the "H" pile and the sides of the holes are expected to reduce the lateral capacity of the soldier pile. In order to provide adequate space for concrete slurry backfilling, we recommend that the web height of the steel "H" pile be at least 10 inches from the diameter of the hole. The concrete and slurry should be placed into the soldier pile excavation from the bottom up using a pump and tremie pipe. The bottom of the tremie pipe should be kept at least 2 to 3 feet below the level of the rising concrete or slurry. The concrete should be thoroughly vibrated to remove any entrapped air. The soil and water mixture dispersed by the concrete and slurry should be pumped into a suitable disposal container. After the soldier piles have been placed, the excavation of the lower pads may begin. If concrete and slurry is used for backfill, these materials should be allowed to cure prior to lower excavations. Care should be taken to ensure that the lagging drops down as the excavation advances. Any gaps in the lagging could cause undermining of the adjacent structures. To prevent caving of the sidewalls, the lagging elements should be forced down either behind the soldier piles or at an appropriate place within the flanges of the "H" and through the existing soils. The slurry materials that were placed within the soldier pile borings may be broken an removed during the lagging process. The lagging elements should not be driven or vibrated into place due to the possible damage that could occur to nearby structures. It should be noted that the shoring should be designed for a minimum safety factor of 1.2 and that the lateral deformation of the ground surface should be controlled by structural design in order to protect the adjacent structures. The shoring should be designed to support the surcharge of any adjacent structures in addition to the earth Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5, 2018 19 21-258 pressures exerted by the native backfill soils. Recommended design values with respect to distribution of earth pressures on shoring elements are presented below. The contractor shall verify the locations of all existing underground utilities prior to commencing the drilling and excavating. Backfilt shall be of compacted spoils or slurry. No vibratory equipment or hammering shall be utilized in the shoring installation. Each caisson boring shall be a min. 24 -inches in diameter, embedded a min. 15 ft. into competent bedrock material. Based on this we assume caissons shall be a minimum 15 feet length at the near -street elevations, and staggered up to 30 feet along the rear row of caissons (all depths below lowest adjacent grade). Caissons may be designated for both end bearing and friction. Caissons may be designed for an allowable bearing capacity of 4,000 psf and a skin friction of 400 psf (neglect the upper 2 feet of old fill). The bearing value may be increased by 113 for wind and seismic forces. The point of fixity of 5 feet below finish grade shall be applied. Channel drains, miradrain, and bentonitic waterproofing shall be installed at each shoring bay (between every caisson). All drains shall be gravity -fed to a suitable outlet. The geotechnical consultant should be present during the excavation and shoring phases of the project to observe the soil conditions and make additional recommendations if necessary. Each borehole bottom shall be free of debris and approved by the geotechnical consultant. Active Earth Pressures For cantilever shoring beams, an active earth pressure (equivalent fluid pressure) of 40 pounds per cubic foot may be considered for the on-site fill and the native soils. It should be noted that under this condition, the movement of shoring H -beams are not restrained so that the soil internal strength can be fully mobilized. Active Pressure 40 pcf The active pressure may be approximated by a rectangular soil pressure distribution with the pressure per foot of width equal to 23H, where H is equal to the depth of the excavation being shored. At -Rest Earth Pressure If movement of the shoring, H -beams are restrained at the top, then an at -rest earth pressure of 55 pounds per cubic foot should be used in design. Proposed 2 -Story COMF]le[alal Otiicc Devclopnim 215 Rivcmide Annuc, Nmpart Bcach, CA soils Report Project No. SLI 48.1 Novcmbv 5, 2018 21-259 Passive Resistance A passive earth pressure increasing at a rate of 400 pounds per square foot per foot of width of a shoring H -beam, per foot of depth, to a maximum value of 4,000 pounds per square foot may be used to determine lateral resistance for H - beams. The passive resistance should be ignored for the upper 2 feet of the H - beams embedded below the lowest cut grade. Active Pressure: 40 pcf At -Rest Pressure: 55 pcf Seismic Earth Pressure and Kh In accordance with Section 1803.5.12 of the 2016 CBC, for design purposes, a seismic earth pressure of 20 pcf (equivalent fluid pressure) may be used for the retaining wall design. This pressure is additional to the static earth pressures and should be considered as the resultant force acting at 1/3 height of the retaining wall (reference: Mononobe-Okabe equation and Atik & Sitar). For complete listing of the resources used, please see Reference Nos. 12 through 15, herein. Assuming level backfill conditions with density of backfill a minimum 110 pcf, the seismic element coefficient Kh = 0.28 (reduction factor = 0.35). Spacingna d Depth of H -beams The minimum clear spacing between the H -beams should be three effective H - beam diameters, sidewall to sidewall. The maximum clear spacing between H - beams should not exceed five effective H -beam diameters, sidewall to sidewall. The embedment depths of the H -beams will likely vary depending on the retained height of the proposed shoring system along its alignment. The structural engineer should determine the final depths based on our recommendations presented herein. However, the H -beams should be embedded, at a minimum, five effective diameters into the underlying competent native deposits. The geotechnical consultant should be present during the excavation and shoring phases of the project to observe the soil conditions and make additional recommendations if necessary. Waterproofing If applicable, lower pad or basement wall/slabs shall be waterproofed in accordance with the 2016 CBC. Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5. 2018 21 21-260 The retaininglshotcrete walls shall be sealed and waterproofed using the miradrain and miraclay (i.e. Grace 3400) waterproofing system, or equivalent. Joint in the membrane shall be lapped and sealed in an approved manner. Protection board shall be used to protect the membrane during and after backfilling. Joints in wafts and floors, and between the wall and floor, and penetrations of the wall and floor shall be made watertight using suitable methods and materials (i.e. bentonite "WaterStops", or "Mira -Stop"). Exterior_Siabs-on-arade Hardsca e Concrete slabs cast against properly compacted fill materials shall be a minimum of 4 inches thick (actual) and reinforced with No. 3 rebar at 18 inches on center in both directions. The reinforcement shall be supported on chairs to insure positioning of the reinforcement at mid -center in the slab. Control joints should be provided at a maximum spacing of 8 feet on center in two directions for slabs and at B feet on center for sidewalks. Control joints are intended to direct cracking. Expansion or felt joints should be used at the interface of exterior slabs on grade and any fixed structures to permit relative movement. Some slab cracking due to shrinkage should be anticipated. The potential for the slab cracking may be reduced by careful control of water/cement ratios. The contractor should take appropriate curing precautions during the pouring of concrete in hot weather to minimize cracking of slabs. New Fences/Garden Walls New fences or garden wall footings, if any, should be founded a minimum of 18 - inches into approved firm materials. To reduce the potential for unsightly cracks due to expansion forces, we recommend inclusion of construction joints at 8 -ft to 15 -ft intervals. Surface Drainage Surface drainage shall be controlled at all times. Positive surface drainage should be provided to direct surface water away from structures and toward the street or suitable drainage facilities. Ponding of water should be avoided adjacent to the structures. Recommended minimum gradient is 2 percent for unpaved areas and one percent for concrete/paved areas. Roof gutter discharge should be directed away from the building areas through solid PVC pipes to suitable discharge points. Area drains should be provided for planter areas and drainage shall be directed away from the top of slopes.

An on site pre -grading meeting should be arranged between the soils engineer and the grading contractor prior to any construction. GEOTECHNICAL OBSERVATION AND TESTING DURING CONSTRUCTION We recommend that a qualified geotechnical consultant be retained to provide geotechnical engineering services, including geotechnical observation/testing, during the construction phase of the project. This is to verify the compliance with the design, specifications and or recommendations, and to allow design changes in the event that subsurface conditions differ from those anticipated. Geotechnical observations/testing should be performed at the following stages: • During ANY grading operations, including excavation, removal, filling, compaction, and backfilling, etc. • After excavations for footings/grade beams and/or drilling for soldier piles/caissons, if any to verify the adequacy of underlying materials. • After pre-soaking of new slab sub -grade earth materials and placement of capillary break, plastic membrane, prior to pouring concrete. • During backfill of drainage and utility line trenches, to verify proper compaction. • When/if any unusual geotechnical conditions are encountered. • Prior to slab pours to ensure proper subgrade compaction and moisture barriers. • During/after installation of water proofing for retaining/basement walls, if any prior to installation of sub-drain/backfilling. • During/after installation of retaining wall sub -drain, prior to backfilling. • During compaction of retaining wall backfill materials to verify proper compaction. • During backfill of drainage and utility line trenches, to verify proper compaction. • When/if any unusual geotechnical conditions are encountered. • Prior to slab pours to ensure proper subgrade compaction and moisture barriers Please schedule an inspection with the geotechnical consultant prior to the pouring of all interior and exterior slabs.

S-' 21-285 APPENDIX C GENERAL EARTHWORKS AND GRADING GUIDELINES 21-286 GENERAL EARTHWORK AND GRADING GUIDELINES GENERAL These guidelines present general procedures and requirements for grading and earthwork including preparation of areas to be filled, placement of fill, installation of subdrains, and excavations. The recommendations contained in the geotechnical report are a part of the earthwork and grading specifications and should supersede the provisions contained herein in the case of conflict. Evaluations performed by the consultant during the course of grading may result in new recommendations which could supersede these specifications or the recommendations of the geotechnical report. II. EARTHWORK OBSERVATION AND TESTING Prior to commencement of grading, a qualified geotechnical consultant should be employed for the purpose of observing earthwork procedures and testing the fills for conformance with the recommendations of the geotechnical report and these specifications. The consultant is to provide adequate testing and observation so that he may determine that the work was accomplished as specified. It should be the responsibility of the contractor to assist the consultant and keep him apprised of work schedules and changes so that the consultant may schedule his personnel accordingly. The contractor is to provide adequate equipment and methods to accomplish the work in accordance with applicable grading codes or agency ordinances, and these specifications. If in the opinion of the consultant, unsatisfactory conditions are resulting in a quality of work less than required in these specifications, the consultant may reject the work and recommend that construction be stopped until the conditions are rectified. Maximum dry density tests used to determine the degree of compaction should Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5, 2018 21-287 be performed in accordance with the American Society for Testing and Materials Test Method ASTM: D 1557. III. PREPARATION OF AREAS TO BE FILLED 1. Clearing and Grubbing: All brush, vegetation, and debris should be removed and otherwise disposed of, 2. Processing: The existing ground which is evaluated to be satisfactory for support of fill should be scarified to a minimum depth of 6 inches. Existing ground which is not satisfactory should be overexcavated as specified in the following section. Scarification should continue until the soils are broken down and free of large clay lumps or clods and until the working surface is reasonably uniform and free of uneven features which would inhibit uniform compaction. 3. Overexcavation: Soft, dry, spongy, or otherwise unsuitable ground, extending to such a depth that surface processing cannot adequately improve the condition, should be over excavated down to firm ground, approved by the consultant. 4. Moisture Conditioning: Over excavated and processed soils should be watered, dried -back, blended, and/or mixed, as necessary to attain a uniform moisture content near optimum. 5. Recompaction: Over excavated and processed soils which have been properly mixed and moisture -conditioned should be recompacted to a minimum relative compaction of 90 percent. 6. Benching: Where fills are to be placed on ground with slopes steeper than 5:1 (horizontal to vertical units), the ground should be benched. The lowest bench should be a minimum of 15 feet wide, and at least 2 feet deep, expose firm material, and be approved by the consultant. Other Proposed 2 -Story Commercial Office Development 215 Riverside Avenue. Newport Beach, CA Soils Report Project No. SL 148 1 Novembcr 5, 2018 2 benches should be excavated in firm material for a minimum width of 4 feet. Ground sloping flatter than 5:1 should be benched or otherwise over excavated when considered necessary by the consultant. 7. Approval: All areas to receive fill, including processed areas, removal areas, and toe -of -fill benches should be approved by the consultant prior to fill placement. IV, FILL MATERIAL 1. General: Material to be placed as fill should be free of organic matter and other deleterious substances, and should be approved by the consultant. Soils of poor gradation, expansion, or strength characteristics should be placed in areas designated by the consultant or mixed with other soils until suitable to serve as satisfactory fill material. 2. Oversize: Oversize material defined as rock, or other irreducible material with a maximum dimension greater than 12 inches, should not be buried or placed in fill, unless the location, materials, and disposal methods are specifically approved by the consultant. Oversize disposal operations should be such that nesting of oversize material does not occur, and such that the oversize material is completely surrounded by compacted or densified fill. Oversize material should not be placed within 10 feet vertically of finish grade or within the range of future utilities or underground construction, unless specifically approved by the consultant. 3. Import: If importing of fill material is necessary for grading, the import material should be approved by the geotechnical consultant. V. FILL PLACEMENT AND COMPACTION 1. Fill Lifts: Approved fill material should be placed in areas prepared to receive fill in near -horizontal layers not exceeding 6 inches in compacted Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5, 2018 3 21-289 thickness. The consultant may approve thicker lifts if testing indicates the grading procedures are such that adequate compaction is being achieved with lifts of greater thickness. Each layer shall be spread evenly and should be thoroughly mixed during spreading to attain uniformity of material and moisture in each layer, 2. Fill Moisture: Fill layers at a moisture content less than optimum should be watered and mixed, and wet fill layers should be aerated by scarification or blended with drier material. Moisture -conditioning and mixing of fill layers should continue until the fill material is at a uniform moisture content at or near optimum. 3. Comlaction of Fill: After each layer has been evenly spread, moisture - conditioned, and mixed, it should be uniformly compacted to not less than 90 percent of maximum dry density. Compaction equipment should be adequately sized and either specifically designed for soil compaction or of proven reliability, to efficiently achieve the specified degree of compaction. 4. Fill Slopes: Compacting of slopes should be accomplished, in addition to normal compacting procedures, by backrolling of slopes with sheepsfoot rollers at frequent increments of 2 to 3 feet in fill elevation gain, or by other methods producing satisfactory results. At the completion of grading, the relative compaction of the slope out to the slope face shall be at least 90 percent. 5. Compaction Testing: Field tests to check the fill moisture and degree of compaction will be performed by the consultant. The location and frequency of tests should be at the consultant's discretion. In general, the tests should be taken at an interval not exceeding 2 feet in vertical rise and/or 1,000 cubic yards of embankment. VI. SUBDRAIN INSTALLATION Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Reporl Project No SL148.1 November 5, 2018 4 21-290 Subdrain systems, if required, should be installed in approved ground and should not be changed or modified without the approval of the consultant, The consultant, however, may recommend and upon approval, direct changes in subdrain line, grade, or material. VII. EXCAVATION Excavations and cut slopes should be examined during grading, If directed by the consultant, further excavation or overexcavation and refilling of cut areas should be performed, and/or remedial grading of cut slopes performed. Where fill -over -cut slopes are to be graded, unless otherwise approved, the cut portion of the slope should be made and approved by the consultant prior to placement of materials for construction of the fill portion of the slope, Proposed 2 -Story Commercial Office Development 215 Riverside Avenue, Newport Beach, CA Soils Report Project No. SL148.1 November 5, 2018 21-291 APPENDIX D USGS Design Maps Detailed Report 21-292 ZUSGS Design Maps Summary Report User -Specified Input Report Title 215 Riverside Avenue, Newport Beach, CA Thu October 18, 2018 04:43:26 UTC Building Code Reference Document ASCE 7-10 Standard (which utilizes USGS hazard data available in 2008) Site Coordinates 33,62190N, 117.92365°W Site Soil Classification Site Class D - "Stiff Soil" Risk Category I/II/III 'Am Aur TOuhtain Vailaay �At 4)M(MEP.

MADE IN U.SA. Product Installation: Apply to Flintlastic SA NailBase, Flintlastic PlyBase and/or Flintlastic SA MidPly Application working with lengths of membrane appropriate for proper handling and the same installation SAI NT-GOBAI N procedure as described for Flintlastic SA MidPly. Overlap side laps 3" and end laps 6". 15 Years Selvage edge with release strip is provided on Flintlastic SA Cap; position roll with selvage SA Cap (FR) edge at the high side of the roof. Once the first cap sheet membrane length is in place, SA MidPly remove the top side lap to release film before overlapping the second length of Flintlastic SA 25 Years/ Cap. Stagger side laps of Flintlastic SA Cap a minimum of 18" from those of the underlying SA Cap (FR) Flintlastic SA MidPly and be certain end laps also are staggered minimum 36". At end laps (or any overlap onto mineral surface), use trowel grade FlintBond" modified bitumen adhesive uniformly in a'/s" to 1/8" layer wherever an overlap exists to ensure an adequate bond. Cut 6.14.2019 opposing corners of end laps diagonally to avoid "T" seam joints. Use a heavy, weighted roller JY to smooth and secure the membrane. Deck Preparation: CertainTeed recommends the use of Flintlastic SA NailBase in conjunction with all self -adhering membrane roof installations on nailable substrates. Non-nailable roof decks may receive direct application of Flintlastic SA PlyBase or Flintlastic SA MidPly followed by Flintlastic SA Cap, provided the deck is thoroughly primed using FlintPrime° SA. It should be noted that without the use of a nailable base sheet, the membrane may be difficult to remove if removal is ever warranted and certain UL listings for the product may not apply. Precautions: Flintlastic SA Cap must be applied as part of a self -adhered system. It is not intended for use with hot asphalt, cold adhesives or torch -down applications. Roof decks must be structurally sound, dry and smooth, and meet or exceed minimum requirements of the deck manufacturer, local code and CertainTeed. Don't attempt application if ice, snow, moisture or dew is present. Surface to be bonded to must be clean, dry and free from any dust or deterrent to adhesion. Ambient temperature must be 50°F or above. Don't attempt installation on roofs without adequate slope and drainage. Additional specifications and precautions are contained in the CertainTeed Commercial Roof Systems Specifications. Storage and Flintlastic SA rolls must be stored above ground indoors and protected from the elements. Handling Rolls that are improperly stored or have been on hand for prolonged periods of time may lose their tack.Do not attempt to install rolls that do not exhibit an adequate bond.

WHERE APPROPRIATE, SEDIMENT CONTROL BMPs SHALL BE IMPLEMENTED AT THE SITE PERIMETER, AT ALL OPERATIONAL STORM DRAIN INLETS, AND AT ALL NON-ACTIVE SLOPES, TO PROVIDE SUFFICIENT PROTECTION FROM STORMS. 2. WIND EROSION BMPs (DUST CONTROL) SHALL BE IMPLEMENTED AND MAINTAINED. 3. BMPs TO CONTROL OFF-SITE SEDIMENT TRACKING SHALL BE IMPLEMENTED AND MAINTAINED. 4. APPROPRIATE WASTE MANAGEMENT AND MATERIALS POLLUTION CONTROL BMPs SHALL BE IMPLEMENTED TO PREVENT THE CONTAMINATION OF STORM WATER BY WASTES AND CONSTRUCTION MATERIALS. 5. APPROPRIATE NON -STORM WATER BMPs SHALL BE IMPLEMENTED TO PREVENT THE CONTAMINATION OF STORM WATER FROM CONSTRUCTION ACTIVITIES. 6. ADEQUATE PHYSICAL OR VEGETATION EROSION CONTROL BMPs (TEMPORARY OR PERMANENT) SHALL BE INSTALLED AND ESTABLISHED AS SOON AS PRACTICAL FOR ALL COMPLETED SLOPES OR SLOPES IN NON-ACTIVE AREAS. THESE BMPs MUST BE MAINTAINED THROUGHOUT THE YEAR. IF A SELECTED BMP FAILS, IT MUST BE REPAIRED AND IMPROVED, OR REPLACED WITH AN ACCEPTABLE ALTERNATE AS SOON AS IT IS SAFE TO DO SO. THE FAILURE OF A BMP MAY INDICATE THAT THE BMP, AS INSTALLED, WAS NOT ADEQUATE FOR THE CIRCUMSTANCES IN WHICH IT WAS USED. REPAIRS OR REPLACEMENTS MUST RESULT IN A MORE ROBUST BMP, OR ADDITIONAL BMPs SHOULD BE INSTALLED TO PROVIDE ADEQUATE PROTECTION. 7. A DISTURBED AREA THAT IS NOT COMPLETED, BY THAT IS NOT BEING ACTIVELY GRADED (NON-ACTIVE AREA), SHALL BE FULLY PROTECTED FROM EROSION WITH TEMPORARY OR PERMANENT BMPs (EROSION AND SEDIMENT CONTROL). THE ABILITY TO DEPLOY STANDBY BMP MATERIALS IS NOT SUFFICIENT FOR THESE AREAS. EROSION AND SEDIMENT CONTROL BMPs MUST ACTUALLY BE DEPLOYED. THIS INCLUDES ALL BUILDING PADS, UNFINISHED ROADS, AND SLOPES. 8. SUFFICIENT MATERIALS NEEDED TO INSTALL STANDBY EROSION AND SEDIMENT CONTROL BMPs NECESSARY TO COMPLETELY PROTECT THE EXPOSED PORTIONS OF THE SITE FROM EROSION AND TO PREVENT SEDIMENT DISCHARGES SHALL BE STORED ON-SITE. AREAS THAT HAVE ALREADY BEEN PROTECTED FROM EROSION USING PERMANENT PHYSICAL STABILIZATION OR ESTABLISHED VEGETATION STABILIZATION BMPs ARE NOT CONSIDERED TO BE "EXPOSED" FOR PURPOSES OF THIS REQUIREMENT. 9. THERE SHALL BE A "WEATHER TRIGGERED" ACTION PLAN AND THE ABILITY TO DEPLOY STANDBY SEDIMENT CONTROL BMPs AS NEEDED TO COMPLETELY PROTECT THE EXPOSED PORTIONS OF THE SITE WITHIN 48 HOURS OF A PREDICTED STORM EVENT (A PREDICTED STORM IS DEFINED AS A FORECASTED, 50% CHANCE OF RAIN). 10. THE AMOUNT OF EXPOSED SOIL ALLOWED AT ONE TIME SHALL NOT EXCEED THAT WHICH CAN BE ADEQUATELY PROTECTED BY DEPLOYING STANDBY EROSION CONTROL AND SEDIMENT CONTROL BMPs PRIOR TO A PREDICTED RAINSTORM. NOTE THE LOCATION AND TYPE OF EROSION AND SEDIMENT CONTROL MEASURES TO BE USED WILL CHANGE DURING THE COURSE OF CONSTRUCTION. THE CONTRACTOR SHALL IMPLEMENT THE CONTROLS NECESSARY TO PREVENT NON-STORMWATER, SEDIMENT, AND CONTAMINATED RUNOFF DISCHARGES FROM THE SITE AT ALL TIMES.
