OWNER: 925 Via Lido Soud, LLC PLANNER: Liz Westmoreland, Associate Planner 949-644-3234 or lwestmoreland@newportbeachca.gov LAND USE AND ZONING •General Plan Land Use Plan Category: RS-D (Single Unit Residential Detached) •Zoning District: R-1 (Single-Unit Residential) •Coastal Land Use Plan Category: RSD-C (Single Unit Residential Detached - (10.0 -19.9 DU/AC)) •Coastal Zoning District: R-1 (Single-Unit Residential) PROJECT SUMMARY The applicant requests a Coastal Development Permit to construct a new bulkhead within private property along the U.S. Bulkhead line at 925 Via Lido Soud, where there are currently no shoreline protective devices to protect existing development on the property. The proposed bulkhead coping would reach 8.75 feet North American Vertical Datum of 1988 (NAVD88) with a stem wall up to 13.5 feet (NAVD88) to match the height of adjacent bulkheads on either side. All work will be performed from the landside of the U.S. Bulkhead Line and all construction would occur from private property (i.e., the landside). The project also includes a grade determination to establish grade for the purposes of measuring height. The proposed grade determination would allow the subject property to construct improvements at a height consistent with the two adjacent properties. RECOMMENDATION 1)Conduct a public hearing; 2)Find this project exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15303 under Class 3 (New Construction or Conversion of Small Structures) of the CEQA Guidelines, California Code of Regulations, Title 14, Division 6, Chapter 3, because it has no potential to have a significant effect on the environment; and 1 925 Via Lido Soud, LLC. Bulkhead (PA2022-025) Zoning Administrator, June 30, 2022 Page 2 3) Adopt Draft Zoning Administrator Resolution No. _ approving Coastal Development Permit No. CD2022-009 and Staff Approval No. SA2022-004 (Attachment No. ZA 1). BACKGROUND Existing Conditions, Setting, and Permit Jurisdiction The property currently consists of one legal lot developed with a single-family residence and garage constructed in 1996. The existing development was issued a Coastal Development Waiver by California Coastal Commission in 1996 (W-5-95-282), which does not include conditions. The neighborhood is predominantly developed with one and two-story single- family residences and almost all of the properties on the south side of Lido Isle include bulkheads. The proposed project is located within the City of Newport Beach Permit Jurisdiction pursuant to the Post LCP Certification Permit and Appeal Jurisdiction Map (“Map”) and is within the Appeal Area of the California Coastal Commission. Pursuant to the Map, the California Coastal Commission retains jurisdiction within tidelands, submerged lands, and lands that are subject to the public trust or were subject to the public trust at any time. The proposed project is adjacent to, but not located within tidelands or lands that are subject to the public trust or were subject to the public trust at any time. The proposed bulkhead is contained entirely within private property and all construction would be conducted without the use of mechanized equipment on the water or sand. Additionally, the project is located outside of submerged lands, which is defined as the lands that lie below the line of mean low tide (from California Code of Regulations Section 13577). Therefore, the project is under the permit jurisdiction of the City of Newport Beach. Proposed Project The applicant requests a Coastal Development Permit to allow for a new bulkhead with a stem wall up to 13.5 feet (NAVD88), which is in line with adjacent bulkheads, reducing any visual impacts. The proposed bulkhead is a standard 8 inches wide, consistent with the footprint of bulkheads in the City. Specifically, construction would include installation of a protective device by utilizing Truline piles with cast-in-place concrete coping and connected with DYWIDAG tiebacks to new concrete deadmen. A staff approval for a grade determination is also requested to allow the subject property to construct improvements at a height consistent with the two adjacent properties following construction of the bulkhead. 2 925 Via Lido Soud, LLC. Bulkhead (PA2022-025) Zoning Administrator, June 30, 2022 Page 3 Off-site Improvements There is an existing glass fence that was inadvertently constructed beyond the private property line within public tidelands. The project is conditioned to require removal of the fence with oversight by the California Coastal Commission since that feature is within their jurisdiction. DISCUSSION Land Use The subject property is located in the R-1 Coastal Zoning District, which provides for single- unit residential development and their appurtenant facilities and is consistent with the City’s Coastal Land Use Plan (CLUP), General Plan, and Zoning Code. A coastal development permit is required and the property is not eligible for a waiver for de minimis development because the property is located in the Coastal Commission Appeal Area. Section 21.30.030 (Natural Landform and Shoreline Protection) Coastal Land Use Plan Policies within Chapter 2 including 2.8.3-6, 2.8.3-5, and 2.8.6-6 are implemented through Newport Beach Municipal Code (NBMC) Section 21.30.030. The project complies with NBMC Section 21.30.030 (Natural Landform and Shoreline Protection)” based on the following: a. In compliance with Subsection (C)(3)(a)(i), the property with an existing single- family residence and garage is not subject to recorded waivers of future protection, as the existing development was issued a Coastal Development Waiver by California Coastal Commission in 1996 (W-5-95-282), which does not include conditions. b. Subsection (C)(3)(a)(ii) requires that the construction of protective structures must be necessary to protect existing development from natural hazards and be located entirely within private property and not within State tidelands. For the purposes of this section, existing development is defined as a principal structure (e.g. residential dwelling, required garage, etc.). The proposed bulkhead is intended to protect the existing single-family residence and garage on-site as well as existing surrounding development including residences at 921 and 929 Via Lido Soud. c. Subsection(C)(3)(b) limits the enlargement and expansion of land areas related to the establishment of shoreline protective structures and prohibits the creation of new useable land areas. All of the land on the subject property is considered usable. As shown on the topographical survey prepared for the property, elevations within the front yard setback (along the water) vary from 10.38 to 12.45 feet (NAVD88), which is typical for new development in the coastal areas of the 3 925 Via Lido Soud, LLC. Bulkhead (PA2022-025) Zoning Administrator, June 30, 2022 Page 4 City. Any future design of a structure using fill would not create new useable land areas. d. Subsection(C)(3)(c) promotes the use of non-structural methods to protect structures, when feasible. Within the Newport Beach harbor, non-structural methods are not employed to protect the residential islands. Non-structural methods in this area are not feasible and cannot be carried out successfully, which is demonstrated by the universal use of bulkheads to maintain a system of harbor bulkheads. e. Subsection(C)(3)(d) contains several provisions related to the design and siting of protective structures such as bulkheads. The proposed bulkhead is located as far landward as possible to align with the neighboring bulkheads and fill a gap in the system of bulkheads. The bulkhead would not impact coastal resources nor access to recreational areas or State tidelands. There are no tidelands adjacent to the site and only a small area of sand off-site that does not connect with any recreational areas or public beaches in the vicinity. The bulkhead would not impact alteration of natural shoreline process, other than reducing the amount of erosion of soils on private property during high tide events. f. The harbor has been physically altered for more than 100 years to assure the public purpose of maintaining a navigable harbor and protecting the shoreline from erosion. The proposed bulkhead would link the existing bulkheads at 921 and 929 Via Lido Soud. Coastal Land Use Plan Policies within Chapter 2 including 2.8.3-6, 2.8.3-5, and 2.8.6-6 are implemented through NBMC Section 21.30.030. Wetlands The proposed bulkhead is not located within wetlands as defined in NBMC Section 21. 70 (Definitions). Wetlands require the presence of at least one characteristic of either (i) land that supports hydrophytes, (ii) undrained hydric soil, or (iii) non-soil substrate covered by water part of the year. The sane soil that surrounds Lido Isle and descends into Newport Harbor is sand that is covered and uncovered by the tides but supports no plants, does not exhibit undrained hydric soil, and is not a non-soil substrate. Thus, the subject location does not contain wetlands. 4 925 Via Lido Soud, LLC. Bulkhead (PA2022-025) Zoning Administrator, June 30, 2022 Page 5 Coastal Hazards A Coastal Hazards Analysis and Engineering Assessment of Need for New Bulkhead Report was prepared by Geosoils, Inc. dated March 11, 2022, for the project (Attachment 3). The report included a summary of the damage observed to the residential structures at and adjacent to the subject site. The report concludes that without a bulkhead at 925 Via Lido Soud (subject property), foundation displacement will eventually damage the structures to the point of foundation failure. Therefore, the proposed bulkhead is necessary to protect existing development from natural hazards. The report describes the property’s shoreline as an intertidal beach. However, there is no beach above the highest tide (i.e., there is no beach exposed when the tide is high). During a very low tide event some wet sand is exposed. The shoreline is generally at the bulkhead line as extended form the adjacent properties. As sea level rises, the shoreline will remain at the bulkhead. The current maximum bay water elevation is 7.7 (NAVD88) (North American Vertical Datum of 1988). The report analyzes future sea level rise scenarios assuming a 3.2-foot increase in the maximum water level (year 2100) over the next 75 years (i.e., the life of the structure). Therefore, the sea level is estimated to reach approximately 10.9 feet (NAVD88) (the likely range for sea level rise over 75-year design life of the structure based on low risk aversion estimates for sea level rise provided by the State of California, Sea Level Rise Guidance: 2018 Update). Without the proposed bulkhead, the rising sea levels will continue to distress the existing and neighboring properties and ultimately public facilities such as roads and utilities. On March 23, 2021, the City Council approved updated Waterfront Project Design Guidelines and Standards, Harbor Design Criteria Commercial & Residential Facilities. The guidelines require that any bulkhead structure permitted within the years 2021 through 2025 must have a minimum bulkhead elevation of 10.9 feet (NAVD88) with a design for adaptability elevation of 14.4 feet (NAVD88). The bulkhead is proposed with a stem wall at an elevation of 13.5 feet (NAVD88) and is designed to be able to accommodate an elevation of 14.4 feet (NAVD88) if needed in the future. Pursuant to NBMC Section 21.30.030(C)(3)(i)(iv), the property owner will be required to enter into an agreement with the City waiving any potential right to protection to address situations in the future in which the development is threatened with damage or destruction by coastal hazards (e.g., waves, erosion, and sea level rise). The Waiver of Future Protection is included as a condition of approval that will need to be satisfied prior to final building inspection. The property owner will also be required to acknowledge any hazards present at the site and unconditionally waive any claim to damage or liability against the decision authority, consistent with NBMC Section 21.30.015(D)(3)(c) – (General Site Planning and Development Standards - Waterfront Development). The Acknowledgement of Coastal Hazards is included as a condition of approval that will need to be satisfied prior to the issuance of building permits. 5 925 Via Lido Soud, LLC. Bulkhead (PA2022-025) Zoning Administrator, June 30, 2022 Page 6 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. Geotechnical investigations specifically addressing liquefaction are required to be reviewed and approved prior to the issuance of a building permit. 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. Water Quality The property is located adjacent to coastal waters. A Construction Erosion Control Plan was provided to implement temporary Best Management Practices (BMPs) during construction to minimize erosion and sedimentation and to minimize pollution of runoff and coastal waters derived by construction chemicals and materials. The project design also addresses water quality through the inclusion of a post-construction drainage system that includes drainage and percolation features designed to retain dry weather and minor rain event runoff on-site. Any water not retained on-site is directed to the City’s storm drain system. Public Access and Views The project site is not located adjacent to a coastal view road, public access way, or Coastal Viewpoint as identified in the Coastal Land Use Plan. The nearest coastal viewpoint is in Marina Park and is not visible from the site. The site is located on the bay, which provides views to boaters of Lido Isle. As currently developed, the existing property and other residences along Via Lido Soud are located within the view shed of the Bay. The subject property and adjacent properties also include residential piers which partially obstruct views of the system of bulkheads as viewed from the water. Additionally, the project does not contain any unique features that could degrade the visual quality of the coastal zone. The project site is located between the nearest public road and the sea or shoreline. Implementation Plan Section 21.30A.040 (Determination of Public Access/Recreation Impacts) requires that the provision of public access bear a reasonable relationship between the requirement and the project’s impact and be proportional to the impact. In this case, the project includes the construction of a new bulkhead to fill a gap in the existing system of bulkheads. The proposed design of the bulkhead is consistent with the existing neighborhood pattern of development and consistent with applicable development standards. Therefore, the project does not involve a change in land use, density or intensity that will result in increased demand on public access and recreation opportunities. Furthermore, the project is designed and sited within private property and outside of public tidelands so as not to block or impede existing public access opportunities. The public currently does not have access through the property to the water and the proposed bulkhead would not interfere with any established public access routes. The bulkhead would become part of the system of bulkheads that is essential to the operation of 6 925 Via Lido Soud, LLC. Bulkhead (PA2022-025) Zoning Administrator, June 30, 2022 Page 7 Newport Harbor, which is open to the public. Access to the water exists throughout Lido Isle and the closest vertical access point located along Via Lido Nord approximately 500 feet north where there is access to the water and a grassy area for the public. The project does not include any features that would obstruct access along these routes. The property is residentially zoned and is not suitable for aquaculture. The property is zoned for residential uses including single-family development that currently exists on the site. Grade Establishment The Applicant is constructing a new bulkhead along the front (bay) property line; however, the grades along the front setback area (waterfront) include depressed areas that are not representative of the prevailing grades on the two (2) adjoining properties. The surrounding properties have front yard elevations on the water of approximately 13.26 feet (NAVD88) at 929 Via Lido Soud and 13.74 to 13.92 feet (NAVD88) at 921 Via Lido Soud. This grade differential creates design constraints and unfairly restricts the heights of accessory structures below those of the neighboring properties. Both adjacent properties also have bulkheads that meet the minimum elevation standards of 10.9 feet (NAVD88) pursuant to the City of Newport Beach Waterfront Project Guidelines and Standards, Harbor Design Criteria Commercial and Residential Facilities. 921 Via Lido Soud has an existing bulkhead that reaches a height of 13.5 feet (NAVD88) and 929 Via Lido Soud has a bulkhead that is 13.38 feet (NAVD88) with additional wall height reaching 16.66 feet (NAVD88). Allowing a higher grade of 13.5 feet (NAVD88), which is an average elevation between the adjacent property’s front yards along the waterfront, would provide the property with a grade elevation that is compatible with those of the neighboring properties and equitable for the purposes of measuring heights of accessory structures and other features. ENVIRONMENTAL REVIEW This project is exempt from the California Environmental Quality Act (CEQA) pursuant to Section 15303 under Class 3 (New Construction or Conversion of Small Structures) of the CEQA Guidelines, California Code of Regulations, Title 14, Division 6, Chapter 3, because it has no potential to have a significant effect on the environment. Class 3 exempts the construction and location of limited numbers of new, small facilities or structures such as accessory (appurtenant structures) such as garages, patios, swimming pools, and fences. The proposed bulkhead is an accessory structure to the primary use of the property as a single-family residence and is therefore consistent with this exemption. There are no known exceptions listed in CEQA Guidelines Section 15300.2 that would invalidate the use of this exemption. The project location does not impact an environmental resource of hazardous or critical concern, does not result in cumulative 7 925 Via Lido Soud, LLC. Bulkhead (PA2022-025) Zoning Administrator, June 30, 2022 Page 8 impacts, does not have a significant effect on the environment due to unusual circumstances, does not damage scenic resources within a state scenic highway, is not a hazardous waste site, and is not identified as a historical resource. PUBLIC NOTICE Notice of this public hearing was published in the Daily Pilot, mailed to all owners and residential occupants of property within 300 feet of the boundaries of the site (excluding intervening rights-of-way and waterways), including the applicant, and posted on the subject property at least 10 days before the scheduled hearing, consistent with the provisions of the Municipal Code. Additionally, the item appeared on the agenda for this meeting, which was posted at City Hall and on the City website. APPEAL PERIOD: This action shall become final and effective 14 days following the date the Resolution is adopted unless within such time an appeal or call for review is filed with the Community Development Director in accordance with the provisions of Title 21 (Local Coastal Program Implementation Plan) of the Newport Beach Municipal Code. Final action taken by the City may be appealed to the Coastal Commission in compliance with Section 21.64.035 (Appeal to the Coastal Commission) of the City’s certified LCP and Title 14 California Code of Regulations, Sections 13111 through 13120, and Section 30603 of the Coastal Act.

SA2022-004 FOR A GRADE DETERMINATION TO CONSTRUCT A NEW BULKHEAD LOCATED AT 925 VIA LIDO SOUD (PA2022-025) THE ZONING ADMINISTRATOR OF THE CITY OF NEWPORT BEACH HEREBY FINDS AS FOLLOWS: SECTION 1. STATEMENT OF FACTS. 1. An application was filed by Sinclair Assciates Architects, Inc., with respect to property located at 925 Via Lido Soud, requesting approval of a coastal development permit and staff approval at the lot legally described as Lot 319 of Tract No. 907. 2. The applicant requests a Coastal Development Permit to construct a new bulkhead within private property along the U.S. Bulkhead line at 925 Via Lido Soud, where there are currently no shoreline protective devices to protect existing development on the property. The proposed bulkhead coping would reach 8.75 feet North American Vertical Datum of 1988 (NAVD88) with a stem wall up to 13.5 feet (NAVD88) to match the height of adjacent bulkheads on either side. All work will be performed from the landside of the U.S. Bulkhead Line and all construction would occur from private property (i.e., the landside). The project also includes a grade determination to establish grade for the purposes of measuring height. The proposed grade determination would allow the subject property to construct improvements at a height consistent with the two (2) adjacent properties. 3. The subject property is designated RS-D (Single Unit Residential Detached) by the General Plan Land Use Element and is located within the R-1 (Single-Unit Residential) Zoning District. 4. The subject property is located within the coastal zone. The Coastal Land Use Plan category is RSD-C (Single Unit Residential Detached - (10.0 - 19.9 DU/AC)) and it is located within the R-1 (Single-Unit Residential) Coastal Zone District. 5. The proposed project is located within the City of Newport Beach Permit Jurisdiction pursuant to the Post LCP Certification Permit and Appeal Jurisdiction Map (“Map”) and is within the Appeal Area of the California Coastal Commission. Pursuant to the Map, the California Coastal Commission retains jurisdiction within tidelands, submerged lands, and lands that are subject to the public trust or were subject to the public trust at any time. The proposed project is adjacent to, but not located within tidelands or lands that are subject to the public trust or were subject to the public trust at any time. The proposed bulkhead is contained entirely within private property and all construction would be conducted without the use of mechanized equipment on the water or sand. Additionally, the project is located outside of submerged lands, which is defined as the lands that lie below the line of mean low tide (from California Code of Regulations Section 13577). Therefore, the project is under the permit jurisdiction of the City of Newport Beach. 10 Zoning Administrator Resolution No. ZA2022-### Page 2 of 12 10-05-2021 6. A public hearing was held on June 30, 2022, online via Zoom. A notice of time, place and purpose of the hearing was given in accordance with the Newport Beach Municipal Code (NBMC). Evidence, both written and oral, was presented to, and considered by, the Zoning Administrator at this hearing. SECTION 2. CALIFORNIA ENVIRONMENTAL QUALITY ACT DETERMINATION. 1. This project is categorically exempt pursuant to Title 14 of the California Code of Regulations Section 15303, Division 6, Chapter 3, Guidelines for Implementation of the California Environmental Quality Act (CEQA) under Class 3 (New Construction or Conversion of Small Structures), because it has no potential to have a significant effect on the environment. 2. Class 3 exempts the construction and location of limited numbers of new, small facilities or structures such as accessory (appurtenant structures) such as garages, patios, swimming pools, and fences. The proposed bulkhead is an accessory structure to the primary use of the property as a single-family residence. 3. The exceptions to this categorical exemption under Section 15300.2 are not applicable. The project location does not impact an environmental resource of hazardous or critical concern, does not result in cumulative impacts, does not have a significant effect on the environment due to unusual circumstances, does not damage scenic resources within a state scenic highway, is not a hazardous waste site, and is not identified as a historical resource. SECTION 3. REQUIRED FINDINGS. In accordance with Section 21.52.015 (Coastal Development Permits, Findings and Decision) of the Newport Beach Municipal Code, 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. Coastal Land Use Plan Policies within Chapter 2 including 2.8.3-6, 2.8.3-5, and 2.8.6-6 are implemented through NBMC Section 21.30.030 (Natural Landform and Shoreline Protection). The project complies with NBMC Section 21.30.030 based on the following facts: a. In compliance with Subsection(C)(3)(a)(i), the property developed with a single- family residence and garage is not subject to recorded waivers of future protection, as the existing development was issued a Coastal Development Waiver by California Coastal Commission in 1996 (W-5-95-282), which does not include conditions. 11 Zoning Administrator Resolution No. ZA2022-### Page 3 of 12 10-05-2021 b.Subsection(C)(3)(a)(ii) requires that the construction of protective structures must be necessary to protect existing development from natural hazards and be located entirely within private property and not within State tidelands. For the purposes of this section, existing development is defined as a principal structure (e.g. residential dwelling, required garage, etc.). The proposed bulkhead is intended to protect the existing single-family residence and garage on-site as well as existing surrounding development including 921 and 929 Via Lido Soud. A Coastal Hazards Analysis and Engineering Assessment of Need for New Bulkhead Report was prepared for the project by Geosoils, Inc. dated March 11, 2022. The report included a summary of the damage observed to the residential structures at and adjacent to the subject site. The report concludes that without a bulkhead at 925 Via Lido Soud (subject property), foundation displacement will eventually damage the structures to the point of foundation failure. Therefore, the proposed bulkhead is necessary to protect existing development from natural hazards. c.Subsection(C)(3)(b) limits the enlargement and expansion of land areas related to the establishment of shoreline protective structures and prohibits the creation of new useable land areas. All of the land on the subject property is considered usable. As shown on the topographical survey prepared for the property, elevations within the front yard setback (along the water) vary from 10.38 to 12.45 feet (NAVD88), which is typical for new development in the coastal areas of the City. Any future design of a structure using fill would not create new useable land areas. d.Subsection(C)(3)(c) promotes the use of non-structural methods to protect structures, when feasible. Within the Newport Beach harbor, non-structural methods are not employed to protect the residential islands. Non-structural methods in this area are not feasible and cannot be carried out successfully, which is demonstrated by the universal use of bulkheads to maintain a system of harbor bulkheads. e.Subsection (C)(3)(d) contains several provisions related to the design and siting of protective structures such as bulkheads. The proposed bulkhead is located as far landward as possible to align with the neighboring bulkheads and fill a gap in the system of bulkheads. The bulkhead would not impact coastal resources (refer to Finding 2) nor access to recreational areas or State tidelands. There are no tidelands adjacent to the site and only a small area of sand off-site that does not connect with any recreational areas or public beaches in the vicinity. The bulkhead would not impact alteration of natural shoreline process, other than reducing the amount of erosion of soils on private property during high tide events. The bulkhead would reach an elevation of 13.5 feet (NAVD88) which is in line with adjacent bulkheads, reducing any visual impacts. Lastly, the bulkhead is a standard 8 inches wide consistent with the footprint of bulkheads in the City. 2.The harbor has been physically altered for more than 100 years to assure the public purpose of maintaining a navigable harbor and protecting the shoreline from erosion. The proposed bulkhead would link the existing bulkheads at 921 and 929 Via Lido Soud. 12 Zoning Administrator Resolution No. ZA2022-### Page 4 of 12 10-05-2021 The proposed bulkhead would fill in a gap in an otherwise continuous bulkhead system that surrounds most of Lido Isle that is not subject to a recorded waiver at this time. 3. The proposed bulkhead is not located within wetlands as defined in NBMC Section 21. 70 (Definitions). Wetlands require the presence of at least one (1)characteristic of either (i) land that supports hydrophytes, (ii) undrained hydric soil, or (iii) non-soil substrate covered by water part of the year. The sane soil that surrounds Lido Isle and descends into Newport Harbor is sand that is covered and uncovered by the tides but supports no plants, does not exhibit undrained hydric soil, and is not a non-soil substrate. Thus, the subject location does not contain wetlands. 4. The neighborhood is predominantly developed with residential uses that are protected by existing bulkheads. The proposed design of the bulkhead is consistent with the existing neighborhood pattern of development along the bay. 5. A Coastal Hazards Analysis and Engineering Assessment of Need for New Bulkhead Report was prepared by Geosoils, Inc. dated March 11, 2022, for the project. The report describes the property’s shoreline as an intertidal beach. However, there is no beach above the highest tide. During a very low tide event some wet sand is exposed. The shoreline is generally at the bulkhead line as extended form the adjacent properties. As sea level rises, the shoreline will remain at the bulkhead. The current maximum bay water elevation is 7.7 (NAVD88). The report analyzes future sea level rise scenarios assuming a 3.2-foot increase in the maximum water level (year 2100) over the next 75 years (i.e. the life of the structure). Therefore, the sea level is estimated to reach approximately 10.9 feet (NAVD88) (the likely range for sea level rise over 75-year design life of the structure based on low risk aversion estimates for sea level rise provided by the State of California, Sea Level Rise Guidance: 2018 Update). Without the proposed bulkhead, the rising sea levels will continue to distress the existing and neighboring properties and ultimately public facilities such as roads and utilities. Refer to Fact 1(b) above. 6. On March 23, 2021, the City Council approved updated Waterfront Project Design Guidelines and Standards, Harbor Design Criteria Commercial & Residential Facilities. The guidelines require that any bulkhead structure permitted within the years 2021 through 2025 must have a minimum bulkhead elevation of 10.9 feet (NAVD88) with a design for adaptability elevation of 14.4 feet (NAVD88). The bulkhead is proposed at an elevation of 13.5 feet (NAVD88) and is designed to be able to accommodate an elevation of 14.4 feet (NAVD88) if needed in the future. 7. Pursuant to NBMC Section 21.30.030(C)(3)(i)(iv), the property owner will be required to enter into an agreement with the City waiving any potential right to protection to address situations in the future in which the development is threatened with damage or destruction by coastal hazards (e.g., waves, erosion, and sea level rise). This requirement is included as a condition of approval that will need to be satisfied prior to final building permit inspection, respectively 8. The property owner will also be required to acknowledge any hazards present at the site and unconditionally waive any claim to damage or liability against the decision authority, 13 Zoning Administrator Resolution No. ZA2022-### Page 5 of 12 10-05-2021 consistent with NBMC Section 21.30.015(D)(3)(c) – (General Site Planning and Development Standards - Waterfront Development). This requirement is included as a condition of approval that will need to be satisfied prior to the issuance of building permits, respectively. 9. The proposed project is requesting a grade determination to establish grade for the front yard for the purpose of measuring new structures. With approval of the grade determination under Findings C and D, the proposed bulkhead would comply with all development standards such as maximum height of accessory structures (NBMC Section 21.30.040 Fences, Hedges, Walls, and Retaining Walls). 10. 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. Geotechnical investigations specifically addressing liquefaction are 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. 11. The property is located adjacent to coastal waters. A Construction Erosion Control Plan was provided to implement temporary Best Management Practices (BMPs) during construction to minimize erosion and sedimentation and to minimize pollution of runoff and coastal waters derived by construction chemicals and materials. The project design also addresses water quality through the inclusion of a post-construction drainage system that includes drainage and percolation features designed to retain dry weather and minor rain event runoff on-site. Any water not retained on-site is directed to the City’s storm drain system. 12. The project site is not located adjacent to a coastal view road, public access way, or Coastal Viewpoint as identified in the Coastal Land Use Plan. The nearest coastal viewpoint is in Marina Park and is not visible from the site. The site is located on the bay, which provides views to boaters of Lido Isle. As currently developed, the existing property and other residences along Via Lido Soud are located within the view shed of the Bay. However, the proposed bulkhead complies with all applicable Local Coastal Program (LCP) development standards and maintains a profile consistent with the existing neighborhood pattern of development along the Bay. The subject property and adjacent properties also include residential piers which partially obstruct views of the system of bulkheads as viewed from the water. Additionally, the project does not contain any unique features that could degrade the visual quality of the coastal zone. 14 Zoning Administrator Resolution No. ZA2022-### Page 6 of 12 10-05-2021 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. Fact in Support of Finding: 1. The project site is located between the nearest public road and the sea or shoreline. Implementation Plan Section 21.30A.040 (Determination of Public Access/Recreation Impacts) requires that the provision of public access bear a reasonable relationship between the requirement and the project’s impact and be proportional to the impact. In this case, the project includes the construction of a new bulkhead to fill a gap in the existing system of bulkheads. Therefore, the project does not involve a change in land use, density or intensity that will result in increased demand on public access and recreation opportunities. Furthermore, the project is designed and sited within private property and outside of public tidelands so as not to block or impede existing public access opportunities. 2. The public currently does not have access through the property to the water and the proposed bulkhead would not interfere with any established or planned public access routes. The bulkhead would become part of the system of bulkheads that is essential to the operation of Newport Harbor. Access to the water exists throughout Lido Isle and the closest vertical access point located along Via Lido Nord approximately 500 feet north where there is access to the water and a grassy area for the public. The project does not include any features that would obstruct access along these routes. The property is not suitable for aquaculture and is zoned for residential uses including single-family development that currently exists on the site. 3. There is an existing glass fence that was likely inadvertently constructed within public property and would be removed as part of the proposed project. Staff Approval for Grade Establishment In accordance with Section 20.30.050 (C) – (Grade Establishment) and 21.30.050 (C) – (Harbor and Bay Regulations) If the Director finds that the existing grade on the subject lot has been previously altered (e.g., contains retaining structures, property line walls, planters, or excavation/fill), or other conditions are present to the degree that the existing grade is not representative of the prevailing grades on adjoining lots and/or the general area and, therefore, is not appropriate for the purpose of establishing the grade of the subject lot, the Director may establish the grade that is reasonable and comparable with the grades of adjoining lots and that will not be detrimental or injurious to property and improvements on adjoining lots. In this case, the proposed bulkhead requires a coastal development permit, and the Zoning Administrator will review the grade determination findings for purposes of measuring height for improvements on the site. 15 Zoning Administrator Resolution No. ZA2022-### Page 7 of 12 10-05-2021 Finding: C. The existing grade on the subject lot has been previously altered (e.g., contains retaining structures, property line walls, planters, or excavation/fill), or other conditions are present to the degree that the existing grade is not representative of the prevailing grades on adjoining lots and/or the general area and, therefore, is not appropriate for the purpose of establishing the grade of the subject lot. Facts in Support of Finding: 1. The Applicant is constructing a new bulkhead along the front (bay) property line; however, the grades along the front setback area (waterfront) include depressed areas that are not representative of the prevailing grades on the two (2) adjoining properties. The two (2) adjacent properties are previously altered with bulkheads. This grade differential creates design constraints and unfairly restricts the heights of accessory structures below those of the neighboring properties. The surrounding properties have front yard elevations on the water of approximately 13.26 feet (NAVD88) at 929 Via Lido Soud and 13.74 to 13.92 feet (NAVD88) at 921 Via Lido Soud. An established grade of 13.5 feet (NAVD88) would be consistent with surrounding properties. 2. The building pad area is generally level and similar to adjacent properties, however, unlike adjacent properties the front of subject site gradually slopes to the water. The subject property is currently developed with a fence and a few stairs within the front yard setback along the waterfront. The existing residence along Via Lido Soud is at a similar grade elevation as the neighboring properties, approximately 13.42 to 14.16 feet (NAVD88). Near the patio of the single-family residence, the grade is approximately 13.95 and gradually slopes to as low as 9.21 feet along the waterfront property line near the wood steps leading to the pier. 3. Both adjacent properties also have bulkheads that meet the minimum elevation standards of 10.9 feet (NAVD88) pursuant to the City of Newport Beach Waterfront Project Guidelines and Standards, Harbor Design Criteria Commercial & Residential Facilities. 921 Via Lido Soud has an existing bulkhead that reaches a height of 13.5 feet (NAVD88) and 929 Via Lido Soud has a bulkhead that is 13.38 feet (NAVD88) with additional wall height reaching 16.66. The proposed bulkhead would provide adequate protection for existing development and allow for comparable measurement of height for improvements. Finding: D. The grade is reasonable and comparable with the grades of adjoining lots and will not be detrimental or injurious to property and improvements on adjoining lots. Fact in Support of Finding: 1. Allowing a higher grade of 13.5 feet (NAVD88), which is an average elevation between the adjacent property’s front yards along the waterfront (13.26 feet and 13.74 feet (NAVD88), respectively), would provide the property with a grade elevation that is 16 Zoning Administrator Resolution No. ZA2022-### Page 8 of 12 10-05-2021 compatible with those of the neighboring properties and equitable for the purposes of measuring heights of accessory structures and other features.

Olson RD Olson Development 520 Newport Center Drive, Suite 600 Newport Beach, CA 92660 SUBJECT: Coastal Hazard Analysis and Engineering Assessment of Need for a New Bulkhead at 925 Via Lido Soud, Newport Beach, CA. Dear Mr. Olson: In accordance with your request and authorization, GeoSoils, Inc. (GSI) is pleased to provide this discussion regarding the coastal hazards, including the impact of future sea level rise (SLR), at 925 Via Lido Soud and a summary of the damage observed to the residential structures at and adjacent to the subject site in support of a new bulkhead. The purpose of this report is to provide the project hazard and bulkhead justification information for your permit application typically requested by the City of Newport Beach and the California Coastal Commission (CCC). Our scope of work includes a review of the State of California Sea-Level Rise (SLR) Policy Guidance document (March 2018), a review of City of Newport Beach Municipal Code (NBMC) 21.30.15.E.2, a review of the proposed bulkhead plans, a site inspection, damage to the adjacent residences and other improvements, evaluation of the need for a bulkhead at the site to protect existing structures from erosion, and preparation of this letter report. INTRODUCTION & SITE INSPECTION The subject site is located on the southeast corner of Lido Isle, in Newport Beach. The site is developed with a single family residence. There is no bulkhead fronting the site, which creates a gap in the almost continuous bulkheads fronting all the other properties in this area of Lido Isle. Figure 1 shows a Bird’s Eye View of the site and adjacent properties downloaded from the internet. The site inspection was performed by the undersigned on January 12, 2022. The site inspection included observations of conditions along the back shoreline at the site, and conditions of the foundations and flat work on the adjacent properties 921 Via Lido Soud and 929 Via Lido Soud. 25 2 Figure 1. Subject site, 925 Via Lido Sound and adjacent properties. As noted above, Lido Island is generally protected by a seawall/bulkhead around its perimeter. Unlike the other 7 islands in Newport Harbor (Balboa, Little Balboa, Collins, Harbor, Bay, Linda, and Newport Islands) Lido Island bulkheads were not installed as a single continuous bulkhead. Rather, each property owner erected its own bulkhead subsequent to the subdivision of Lido Isle in the 1920’s. Generally, the bulkheads followed the Federally designated “bulkhead line”. INSPECTION OBSERVATIONS 929 Via Lido Soud The property line wall between the site and 929 Via Lido Soud is, for the most part, obscured by landscaping hedges. However, the bayward ~10 feet of the wall was experiencing water damage (staining and finish bubbling) from bay waters coming thru the gap in the shore protection. The saturation of the site soils due to bay water intrusion 26 3 weakens the sandy soils adjacent to the wall and the 929 Via Lido Soud residence foundation. Saturation is most prevalent in the periodic inundation of the sandy subsoils beneath the foundation at and during peak tides. The frequency and duration of such peak tides have increased over the past 100 years and can be expected to increase further in the future. The 929 Via Lido Soud residence has a basement, which was inspected. The corner of the residence foundation wall directly adjacent to the site and nearest the bay showed signs of ongoing distress. The foundation wall was cracked and the crack geometry was such that it appears that the corner is settling towards the bay and slightly towards the property. Figure 2 shows the crack directly in the residence foundation. The settlement is likely caused by lateral spreading of the site soils away from the foundation and towards the bay when they are periodically inundated by the bay waters. Figure 2. Foundation cracks at 929 Via Lido Soud due to soil movement. 27 4 921 Via Lido Soud The residence at 921 Via Lido Soud is showing signs of foundation displacement shown in the patio settlement at the shared property line with the site. Like on 929 Via Lido Soud, lateral spreading of the soils adjacent to the foundation and the patio. This result in settlement of the residence and settlement of the patio along with distressed (offset cracks) flat work. Figure 3 shows the foundation of 921 Via Lido Soud has settled about ½ inch as a result of the sandy soils on the site moving away from the foundation and towards the bay. As noted above, the frequency and duration of this adverse soil saturation is project to increase in the future. Figure 3. Settlement of the foundation closest to the site property line and the bay. Note the cracked and displaced tiles(flat work) in the fore ground. The return wall from the 921 Via Lido Soud bulkhead, along the site shared property line, is just a retaining wall with a traditional wall footing (not deepened). It is not designed like a bulkhead, which extends down several feet. The saturation of the site soils by bay water, and the lateral spreading of the soils adjacent to the return wall has resulted in the distress to both the patio flat work (differential cracks) and rotation of the return wall towards the site. Figure 4 shows this distress observed during the site inspection. 28 5 Figure 4. Bulkhead return wall at 921 Via Lido Soud rotation and damage in the form of settlement and cracking of the patio behind the bulkhead and adjacent to the return. 925 Via Lido Soud The intrusion of the bay waters onto the site has resulted in a bayward movement of sand. The soils next to the foundation of the adjacent residences become saturated and spread laterally away for the foundation due to the foundation loading. The innundation is evidence by the landscaping that was died from salt water. The sand on the site has moved bayward as shown in Figure 5. Over the 90+ years since the subdivision of Lido Isle for residential purposes, sea level rise has increased the duration and frequency of the soil saturation events, which lead to damage to the structures at 921, 925 and 929 Via Lido Soud. The Coastal Commission Sea Level Rise Guidance advises that this sea level rise will accelerate in the future, further increasing the duration and frequency of soil saturation. 29 6 Without a bulkhead at 925 Via Lido Soud, foundation displacement as described above will further damage the structures eventually to the point of foundation failure. Figure 5. Photograph showing the damaged areas at 921 Via Lido Sound and the site. HAZARD ANALYSIS There are three different potential shoreline hazards identified at this site: shoreline movement/erosion, waves and wave runup, and flooding. For ease of review, each of these hazards will be analyzed and discussed separately, followed by a summary of the analysis including conclusions and recommendations, as necessary. Shoreline Erosion Hazard The is an intertidal beach at the site. However, there is no beach above the highest tide. During an very low tide some wet sand is exposed (Figure 5). Due to the fact that the site is on a channel on the south side of Lido Island, the shoreline is located essentially at the bulkhead line as extend from the adjacent properties. The proposed project is to install a new bulkhead at the site. As sea level rises the shoreline will remain at the bulkhead. The proposed bulkhead meets the current City requirements with regards to the top of bulkhead 30 7 elevation and the ability to adapt to SLR. The bulkhead height can be increased without any bayward encroachment. The proposed bulkhead is designed such that shoreline erosion will not impact the site and the adjacent properties over the life of the development. Current Flooding Hazard The National Oceanographic and Atmospheric (NOAA) National Ocean Survey tidal data station closest to the site with a long tidal record (Everest International Consultants Inc. (EICI), 2011) is located at Los Angeles Harbor (Station 94106600). The tidal datum elevations are as follows: Mean High Water 4.55 feet Mean Tide Level (MSL) 2.62 feet Mean Low Water 0.74 feet NAVD88 0.0 feet Mean Lower Low Water -0.2 feet During storm conditions, the sea surface rises along the shoreline (super-elevation) and allows waves to break closer to the shoreline and runup on the beach. Super-elevation of the sea surface can be accounted for by: wave set-up, wind set-up and inverse barometer, wave group effects and El Niño sea level effects. The historical highest ocean water elevation at the Los Angeles Harbor Tide station is +7.72 feet NAVD88 on January 10, 2005. In addition, EICI reported that the elevation of 7.71 feet NAVD88 is the 1% water elevation. For this analysis the historical highest water elevation will be +7.7 feet NAVD88. Future Tide Levels Due to Sea Level Rise The November 2018 California Coastal Commission (CCC) SLR Guidance Update document recommends that a project designer determine the range of SLR using the “best available science.” The California Ocean Protection Council (COPC) adopted an update to the State’s Sea-Level Rise Guidance in March 2018 which the CCC has adopted in November 2018. These estimates are based upon a 2014 report entitled “Probabilistic 21st and 22nd century sea-level projections at a global network of tide-gauge sites” (Kopp el at, 2014). This update included SLR estimates and probabilities for Los Angeles Harbor, the closest SLR estimates to Newport Bay. The report provides SLR estimates based upon various carbon emission scenarios known as a “representative concentration pathway” or RCP. Figure 6 provides the March 2018 COPC data (from the Kopp et al 2014 report) with the latest SLR adopted estimates (in feet) and the probabilities of those estimate to meet or exceed the 1991-2009 mean. 31 8 Figure 6. Table from Kopp et al (2014) and COPC 2018, providing current SLR estimates and probabilities for the Los Angeles Harbor tide station. The CCC SLR Guidance (CCCSLRG) is based upon the California Ocean Protection Council (COPC) update to the State’s Sea-Level Rise Guidance in March 2018. These COPC estimates are based upon a 2014 report by Kopp, et al., 2014. The Kopp et al. paper used 2009 to 2012 SLR modeling by climate scientists for the probability analysis, which means the “best available science” used by the CCC is about 10 years old. The SLR models used as the basis for the COPC and CCCSLRG have been in place for over a couple decades. The accuracy of any model can be determined by comparing the measured SLR (real data) to the model predicted SLR (model prediction). If the model cannot predict, with any accuracy, what will happen in the past, it is very unlikely that the model will increase in accuracy when predicting SLR over the next 75 years. Simply put, if the model is not accurate now, it will be even less accurate in the future. The National Oceanic and Atmospheric Administration (NOAA) has been measuring SLR globally and at Los Angeles Harbor. The NOAA Los Angeles Harbor SLR rate is 1.03 mm/yr. The rate can be used to calculate a sea level rise of 30.9 mm (0.1 ft) over the last 22 years and next 8 years (Jan 2000 to Jan 2030), a period of 30 years. NOAA also provides the latest SLR model curves and tables for the Los Angeles Harbor NOAA Station. Figure 7 provides the SLR model curves and tables for Los Angeles Harbor. 32 9 Figure 7. Taken from the USACOE SLR curve calculator program. Looking at the table in Figure 7, the SLR base value in the year 2000 is 2.70 feet. Adding 0.1 feet to the base SLR value yields the value 2.8 for the year 2030. The model that most closely predicts the currently measured SLR is the NOAA 2017 Low Model. This NOAA model predicts about 1.5 feet of SLR in the year 2100. Examining Figure 6 for the year 2030 and 0.1 feet of SLR, the closest probability category is the lower limits of the “Likely Range.” The CCCSLRG document recommends that a project designer determine the range of SLR using the “best available science.” The information provided above is more current than the CCCSLRG. The checking of the models provides the “best available science” for SLR prediction and is required to be used. Currently, the SLR model that the CCC is “requiring” to be used for development is incorrect by a factor of about 4 as to the amount of the SLR in Los Angeles. Figure 6 illustrates that SLR in the year 2100 for the Likely Range, and considering the most onerous RCP (8.5), is 1.3 feet to 3.2 feet above the 1991-2009 mean. In addition, based upon this 2018 COPC SLR report, the 5% probability SLR for the project is estimated to be less than 4.1 feet and a 0.5% probability that SLR will be between 5 feet and 6 feet in the year 2097. This 0.5% SLR is based upon the interpolation of the low 33 10 estimates and the high estimates for 2090 and 2100, recognizing that the interpolation is exponential and not linear( (4.5 + 5.4)/2 = ~5 and (5.3 + 6.7)/2 = ~6 feet)). The design historical water elevation for Newport Bay is elevation +7.7 feet NAVD88. This actual high water record period includes the 1982-83 severe El Niño, and the 1997 El Niño events, and is therefore consistent with the methodology outlined in the CCCSLRG document. The “likely” sea level rise range for the proposed project is 1.3 feet to 3.2 feet with a lower probability (~5%) of SLR of about 4.0 feet. This SLR range would account for future extreme bay water levels in the range of 9 feet NAVD88 (7.7 feet NAVD88 + 1.3 feet SLR) and 10.9 feet NAVD88 (7.7 feet NAVD88 + 3.2 feet SLR). There is a 0.5% probability that bay water will meet or exceed 13.7 feet NAVD88 (7.7 feet NAVD88 + 6 feet SLR). The top of the proposed bulkhead is at elevation 13.13 feet NAVD88. As stated before, the present maximum historical water elevation at the site, including El Niño effects, is ~+7.7 feet NAVD88. Based upon the initial elevation of the bulkhead (+13.13 feet NAVD88), the extreme Lower Newport Bay water level will exceed the height of the bulkhead when SLR is 5.4 feet or greater. For the likely COPC SLR estimate range (high emissions) the bulkhead is safe from overtopping beyond the year 2110. For SLR greater than 5.4 feet the height of the bulkhead will need to be increased. For the 0.5% probability SLR case this may occur after the year 2090. It should be noted that, if the bay water is higher than the bulkhead, flooding will not occur constantly but rather only a few times a month, at the full moon and new moon, for a period of about 1 hour. The City of Newport Beach has recognized that in the future there will be a need to raise the elevation of the boardwalks and bulkheads around the Newport Bay. The City of Newport Beach Building Department (CNBBD) has a standard drawing, and a regional plan for rehabilitating and raising the bulkheads. Flooding from the bay and from the beach will result in flooding of the public roads in the Newport Beach area. Recent action by the City Council has raised the minimum bulkhead elevation for new development to be 10.9 feet NAVD88. In addition, the updated Waterfront Project Design Guidelines and Standards require that the bulkhead can be design to accommodate an increase in height to +14.4 feet NAVD88. Based upon our visual inspection and review of the bulkhead plans, the existing bulkhead system is capable of being extended in height to a least +14.4 feet NAVD88. Waves and Wave Runup The potential surface gravity waves (ocean swell) to arrive at this site is nil. Boat wakes and wind waves are the only possible waves that can reach the bulkhead fronting the site. Wave runup and overtopping of the proposed bulkhead at the site is calculated using the USACOE Automated Coastal Engineering System, ACES. ACES is an interactive computer-based design and analysis system in the field of coastal engineering. The methods to calculate wave runup and shore protection overtopping implemented within this ACES application are discussed in greater detail in the 2004 Coastal Engineering Manual. A 0.75-foot high wave was used in the ACES wave runup and overtopping analysis with a current maximum historical water level of +7.7 feet NAVD88 (no SLR) and the base of the proposed bulkhead at 0.5 feet NAVD88. This combination of wave and water level 34 11 represents an approximate 100-year recurrence interval oceanographic condition under current sea level. Table I below is the computed output from the ACES program for the wave runup analysis. TABLE I The calculated maximum wave runup under the current 100-year recurrence interval conditions is just about 0.8 feet above the historical 100-year water level, or about 8.5 feet NAVD88. This is currently well below the elevation of the proposed shore protection (+13.13 feet NAVD88). In the future, with more than 4.7 feet of SLR, boat wakes during the highest high tides may overtop the shore protection. As shown in the plans, the shore protection can be increased in height without any bayward encroachment. This is a SLR adaptation strategy as recommended in the CCCSLRG document. Tsunami Tsunami are waves generated by submarine earthquakes, landslides, or volcanic action. Lander, et al. (1993) discusses the frequency and magnitude of recorded or observed tsunami in the southern California area. James Houston (1980) predicts a tsunami of less than 5 feet for a 500-year recurrence interval for this area. Legg, et al. (2002) examined the potential tsunami wave runup in southern California. While this study is not specific to the site, it provides a first order analysis for the area. The Legg, et al. (2002) report determined a maximum open ocean tsunami height of less than 2 meters. The maximum tsunami runup in the Newport Beach open coast area is less than 1 meters in height. Any wave, including a tsunami, that approaches the site in will be refracted, modified, and reduced in height by the Newport jetties, and as it travels into the bay. Due to the infrequent nature and the relatively low 500-year recurrence interval tsunami wave height, and the elevation of the proposed improvements, the site is reasonably safe from tsunami hazards. 35 12 It should be noted that the site is mapped within the limits of the California Office of Emergency Services tsunami innundation map, Newport Beach Quadrangle (State of California, 2011). The tsunami inundation maps are very specific as to their use. Their use is for evacuation planning only. The limitation on the use of the maps is clearly stated in the PURPOSE OF THIS MAP on every quadrangle of California coastline. In addition, the following paragraph is taken from the CalOES Local Planning Guidance on Tsunami Response concerning the use of the tsunami inundation maps. Inundation projections and resulting planning maps are to be used for emergency planning purposes only. They are not based on a specific earthquake and tsunami. Areas actually inundated by a specific tsunami can vary from those predicted. The inundation maps are not a prediction of the performance, in an earthquake or tsunami, of any structure within or outside of the projected inundation area. The City of Newport Beach and County of Orange have clearly marked tsunami evacuation routes for the entire Newport Beach/Bay area. CITY OF NEWPORT BEACH INFORMATION Coastal Hazards Report (NBMC 21.30.15.E.2): i. A statement of the preparer’s qualifications; Mr. Skelly is Vice President and Principal Engineer for GeoSoils, Inc. (GSI). He has worked with GSI for several decades on numerous land development projects throughout California. Mr. Skelly has over 45 years experience in coastal engineering. Prior to joining the GSI team, he worked as a research engineer at the Center for Coastal Studies at Scripps Institution of Oceanography for 17 years. During his tenure at Scripps, Mr. Skelly worked on coastal erosion problems throughout the world. He has written numerous technical reports and published papers on these projects. He was a co-author of a major Coast of California Storm and Tidal Wave Study report. He has extensive experience with coastal processes in southern California. Mr. Skelly also performs wave shoring and uprush analysis for coastal development, and analyzes coastal processes, wave forces, water elevation, longshore transport of sand, and coastal erosion. ii. Identification of coastal hazards affecting the site; As stated in this hazard analysis, the typical coastal hazards to consider are shoreline erosion, flooding, and wave/wake impacts. There is no beach above the highest water fronting the site. Boat wakes and wind waves are too small, even with sea level rise (SLR), to overtop the proposed bulkhead. There is no potential coastal hazard of flooding provided adaptation strategies such as increasing the height of the bulkhead are implemented, if required in the future. 36 13 iii. An analysis of the following conditions: 1. A seasonally eroded beach combined with long-term (75 year) erosion factoring in sea level rise; There is no beach fronting the site. 2. High tide conditions, combined with long-term (75 year) projections for sea level rise; Using the likely CCC SLR estimate over the project 75-year design life, the SLR in the year ~2097 is 3.2 feet. There is a 0.5% probability that SLR could be 6 feet in the next 75 years. This is the design sea level rise range (3.2 feet to 6 feet) for the proposed project. This SLR would account for future extreme bay water level of 10.9 feet NAVD88 to 13.7 feet NAVD88. 3. Storm waves from a one hundred year event or storm that compares to the 1982/83 El Nino event; No ocean waves can reach the site. The analysis herein shows that boat wakes and wind waves will not impact the project. 4. An analysis of bluff stability; a quantitative slope stability analysis that shows either that the bluff currently possesses a factor of safety against sliding of all least 1.5 under static conditions, and 1.1 under seismic (pseudostatic conditions); or the distance from the bluff edge needed to achieve these factors of safety; and There is no bluff fronting the site. This condition does not occur at the site. 5. Demonstration that development will be sited such that it maintains a factor of safety against sliding of at least 1.5 under static conditions and 1.1 under seismic (pseudostatic) conditions for its economic life (generally 75 years). This generally means that that setback necessary to achieve a factor of safety of 1.5 (static) and 1.1 (pseudostatic) today must be added to the expected amount of bluff erosion over the economic life of the development (generally 75 years); There is no bluff fronting the site. There is no potential for sliding. This condition does not occur at the site. iv. On sites with an existing bulkhead, a determination as to whether the existing bulkhead can be removed and/or the existing or a replacement bulkhead is required to protect existing principal structures and adjacent development or public facilities on the site or in the surrounding areas; and 37 14 There is no existing bulkhead. The proposed bulkhead is necessary to protect the existing structure, the adjacent structures (921 & 929 Via Lido Soud), and the public facilities and infrastructure. v. Identification of necessary mitigation measures to address current hazardous conditions such as siting development away from hazardous areas and elevating the finished floor of structures to be at or above the base floor elevation including measures that may be required in the future to address increased erosion and flooding due to sea level rise such as waterproofing, flood shields, watertight doors, moveable floodwalls, partitions, water- resistive sealant devices, sandbagging and other similar flood-proofing techniques. The project is safe from the coastal hazard of flooding by the proposed initial elevation of the top of the bulkhead (13.13 feet NAVD88). To further adapt to SLR, the shore protection can be increased in height to above +14.4 feet NAVD88, in the future. It is important to point out that SLR will not impact this property alone. It will impact all of the Newport Bay low lying areas. The public streets throughout the Newport Beach coastal area, including Balboa Island and the Balboa Peninsula, will flood with lower SLR well before the residence floods. It is very likely that the community will soon adopt some of the SLR adaptation strategies that are currently being considered by the City of Newport Beach. These strategies involve raising, or adding/replacing the bulkheads, beaches and walkways that surround the bay, and waterproofing. These are a site specific adaptation strategies. ADDITIONAL INFORMATION The majority of Lido Isle is protected by private bulkheads. In the site area all of the residences are protected by bulkheads with the exception of the site. Other areas without a bulkhead proper are protected by retaining walls that exclude the bay waters. These areas include behind the public boardwalk on the north west side of the island and some street ends. These bulkheads and walls are essentially to prevent flooding of the island during King Tides. The City of Newport Beach produced a Public Trust Lands Sea Level Rise Vulnerability Assessment in 2019. Currently, the City is working on increasing the height of the city owned seawall around Balboa Island. Balboa Island street and residence elevations are a few feet lower than Lido Isle streets and residences. While the City may incorporate other sea level rise (SLR) adaptation strategies such as planned retreat and beach nourishment for other parts of the community, it appears that at this time the City is using the “hold the line” SLR adaptation strategy for the island communities. This makes sense for the 8 island communities within Newport Bay. On Lido Isle the bulkheads are privately owned so increasing them in height to adapt to SLR will not involve public money. The installation of a bulkhead/seawall at the site, paid by the property owner, is consistent with the overall City SLR resiliency efforts at this time. The site does not have a bulkhead. City policy encourages installation, maintenance and 38 15 improvement of bulkheads to protect structures. (See, City LUP Policy 2.8.6-5) Filling existing gaps in Lido Island bulkheads is essential to the protection of the residential structures and the public infrastructure (streets, utilities, storm drains) which have been constructed over the past 100 years. One of the important aspects of construction of a bulkhead at the subject site is that the work can be performed entirely from the private property. The work would take place well above the Mean High Tide. No equipment will need to be on public lands. The proposed new bulkhead is a “deadman” restrained pile design with a concrete cap top than can be adapted to SLR. The seawall is designed to protect the low lying portions of Lido Ilse behind it including public roads and infrastructure (utilities). CONCLUSIONS A new bulkhead/seawall is needed at the subject site to stop the ongoing and increasing distress to the adjacent residence foundations and other improvements (deck and patio). The damage to these adjacent residences is from lateral spreading of unconfined soils on the subject site. The proposed bulkhead is necessary to protect these existing structures threatened by natural hazards and is in alignment with the bulkheads on the adjacent properties. A new bulkhead will confine the site soils and stop the progression of the damage to the residence foundations. A new bulkhead will provide protection of Lido Isle in consideration of SLR and is consistent with the SLR adaptation strategy for Newport Bay island communities. Finally, the construction of the bulkhead will be entirely on and accomplished from private property. Based upon our review of the proposed plans the bulkhead meets the current requirements for new bulkheads in the City of Newport Beach. We appreciate this opportunity to be of service.

The topographic survey on handwritten page 46 indicates the it is built on a grade that is already at 13.8 feet elevation, which is higher than the top of the proposed bulkhead. Handwritten page 10, Section 1.2: “The proposed bulkhead coping would reach 8.75 feet North American Vertical Datum of 1988 (NAVD88) with a stem wall up to 13.5 feet (NAVD88) to match the height of adjacent bulkheads on either side.” Comment: I have trouble visualizing what this is attempting to describe, mostly because I don’t understand the use of the term “stem wall” – something I gather usually refers to a wall to which further (and taller) vertical structures are attached. I see the term used on handwritten page 45, but it doesn’t look like it is intended for anything further to be bolted to it. Is it regarded as a functional part of the bulkhead? Handwritten page 10, Section 1.5: “The proposed project is located within the City of Newport Beach Permit Jurisdiction pursuant to the Post LCP Certification Permit and Appeal Jurisdiction Map …” Comment: I am not sure the jurisdictional issue is a simple as presented. Some tidelands boundaries are actual while others may be adjudicated. The map appears to show the “permit jurisdiction” extending to the property line, and the City’s own Tidelands Survey appears to show the tidelands having the same extent. Handwritten page 11, Section 2.1: “This project is categorically exempt pursuant to Title 14 of the California Code of Regulations Section 15303, Division 6, Chapter 3, Guidelines for Implementation of the California Environmental Quality Act (CEQA) under Class 3 (New Construction or Conversion of Small Structures), because it has no potential to have a significant effect on the environment.” Comment: This CEQA finding is not obvious to me. I believe the Coastal Commission’s aversion to granting CDPs for new shoreline protective devices is based precisely on the assumption they will have significant long-term adverse impacts on the environment.

Do they have waivers? If so, wouldn’t adding a wall at 925 to protect them be in violation of the waivers? Handwritten page 12, Section 3.A.1.b: This statement of fact seems to confirm the purpose of the development is to protect the adjacent properties, not the subject one. It is good to see the Coastal Hazards Analysis and Engineering Assessment of Need for New Bulkhead Report included for review with the staff report. Handwritten page 12, Section 3.A.1.d: “Non-structural methods in this area are not feasible and cannot be carried out successfully, which is demonstrated by the universal use of bulkheads to maintain a system of harbor bulkheads.” Comment: I see no basis presented to support what seems a conclusory statement. Indeed, to the best of my knowledge bulkheads are not universal in Newport Harbor. For example, I don’t think there are any on some of the Bay Island properties facing this location. Handwritten page 12, Section 3.A.1.e: “There are no tidelands adjacent to the site and only a small area of sand off-site that does not connect with any recreational areas or public beaches in the vicinity.” Comment: This seems a strange statement. If there is a sand area beyond the property line, whether tidelands or not, is it not a public beach? Handwritten page 12, Section 3.A.1.e: “The bulkhead would not impact alteration of natural shoreline process, other than reducing the amount of erosion of soils on private property during high tide events.” Comment: Really? Isn’t the very purpose of a bulkhead to alter natural shoreline processes? Handwritten page 13, Section 3.A.3: “The sane sand soil that surrounds Lido Isle and descends into Newport Harbor is sand that is covered and uncovered by the tides but supports no plants, does not exhibit undrained hydric soil, and is not a non-soil substrate.” [?] Thus, the subject location does not contain wetlands.” Handwritten page 13, Section 3.A.5: “The report describes the property’s shoreline as an intertidal beach. However, there is no beach above the highest tide. During a very low tide event some wet sand is exposed. The shoreline is generally at the bulkhead line as extended form the adjacent properties.” Comment: This statement of “fact” is contradicted by at multiple pieces of evidence. First, the photo on handwritten page 30 appears to show a width of dry sandy beach between the glass wall and the wet sand. Second, the topographic survey on handwritten page 46 puts the Mean High Tide Line well beyond the property line where the bulkhead is proposed. Third, the bulkhead design drawing on handwritten page 45 puts both the Mean High Water and Mean Zoning Administrator - June 30, 2022 Item No. 2a Additional Materials Received 925 Via Lido Soud, LLC Bulkhead CDP_PA2022-025 June 30, 2021, ZA agenda Item 2 comments - Jim Mosher Page 3 of 3 Higher High Water levels well below the 8.0’ NAVD 88 mudline level of the base of the proposed wall, which is itself below the natural grade of 9.21’ feet at the property line shown on the topographic survey. Finally, from handwritten page 35, “the calculated maximum wave runup” is anticipated to reach only 8.5 feet NAVD 88. Handwritten page 14, Section 3.A.9: “With approval of the grade determination under Findings C and D, the proposed bulkhead would comply with all development standards such as maximum height of accessory structures (NBMC Section 21.30.040 Fences, Hedges, Walls, and Retaining Walls).” Comment: Does this imply that without the grade determination it would not? Handwritten page 14, Section 3.A.12: “… the project does not contain any unique features that could degrade the visual quality of the coastal zone.” Comment: Couldn’t a bulkhead degrade the visual quality of the coastal zone even if it isn’t unique? Handwritten page 16: The grade determination findings do not address why the adjacent lots are higher. Were they filled after construction of their bulkheads? Is that justification for ignoring the clear natural grade of this lot? Zoning Administrator - June 30, 2022 Item No. 2a Additional Materials Received 925 Via Lido Soud, LLC Bulkhead CDP_PA2022-025
