Jurisdictions with a state- certified local coastal program can authorize development consistent with the plan on behalf of the California Coastal Commission. This transfer of permit authority from the Coastal Commission to the City of Carlsbad simplifies the review process and saves applicants and the city substantial costs and time in approving public and private development projects. The city’s current Local Coastal Program was certified by the state in the 1980s and, while amendments have been made to the document over time, the city’s Local Coastal Program has not been comprehensively updated since its initial adoption. Oct. 12, 2021 Item #7 Page 1 of 428 The city began a comprehensive update to its Local Coastal Program in 2014 so that it would be consistent with the pending update of the city’s General Plan and address new land use and environmental challenges, such as sea level rise. After substantial study and public engagement, the updated program is now being presented before the City Council for its consideration. Some of the key policy changes in the document address the following topics: • Sea level rise hazards • Scenic and visual resources • Lower-cost visitor accommodations and timeshares • Zoning on the power plant and strawberry field sites • Policy inconsistencies related to the Poinsettia Shores Master Plan and Planning Area F • This staff report provides a general overview of staff’s approach to the comprehensive update and summarizes the need and reasons for these key policy changes. The draft Local Coastal Program can be found in Exhibit 3. Discussion Background The effort to update Carlsbad’s Local Coastal Program was initiated for multiple reasons, including the needs to address new guidance from the Coastal Commission on topics such as sea level rise, update policies that have become obsolete over time, and combine the six existing land use plans in the Local Coastal Program into a single land use plan. Additionally, in September 2015, the City Council approved a comprehensive update to the city’s General Plan, which includes a policy (2- P.2) that requires the program to be updated consistent with the General Plan. In November and December 2014, the Coastal Commission and the California Ocean Protection Council awarded the city two grants totaling $228,000 to fund a sea level rise vulnerability analysis and partially fund a comprehensive update to the city’s Local Coastal Program. In October 2015, the City Council approved a professional services agreement with a consulting firm, Michael Baker International, to prepare the sea level rise analysis and comprehensive Local Coastal Program update. Local Coastal Program update approach Given the scope of work described above, this update does not include a reevaluation of the land uses in the Coastal Zone,1 but instead relies on the land use planning done for the update of 2015 General Plan. The General Plan included the development of the Carlsbad Community Vision, as well as analysis of the future use of vacant and underdeveloped lands throughout the city. These efforts resulted in the “preferred land use plan” recommended by a 19-member citizens advisory committee, the Planning Commission and approved by the City Council. Although over five years have passed since the General Plan was adopted, it remains relevant and applicable to this update. 1 The Coastal Zone, established in 1977, demarks the area under the authority of the Coastal Commission, as outlined in the California Coastal Act. Coastal Zone in Carlsbad Oct. 12, 2021 Item #7 Page 2 of 428 The land use policies in both documents are intended to guide development for at least 20 years. (The time horizon of the General Plan is the year 2035 as stated in General Plan Section 1.4). Long- range, comprehensive land use planning efforts are not conducted on a regular basis and require significant time and resources. On occasion, however, in between comprehensive updates, the city may decide there is a need to reevaluate land use policies for a specific site or area and initiate a site or area-specific planning effort. The scope of work for the Local Coastal Program update does not reevaluate the land use for any site, except in the context of updating the program’s existing land use policies to make them consistent with the General Plan approved, after extensive outreach, in 2015. (Additional information on the update of the Local Coastal Program can be found in the Planning Commission staff report (Exhibit 5). Community engagement The process of updating the Local Coastal Program engaged the community through several stages that covered many critical components of the update. The public input gathered provided a foundation for the update. Public outreach efforts included: • Extensive community participation effort conducted for the 2015 General Plan update o About 8,000 community members directly participated in activities such as workshops, community survey, and other public meetings, including a 19-member citizens advisory committee. • Community engagement conducted for the preparation of the City of Carlsbad Sea Level Rise Vulnerability Assessment o Two community workshops:  May 2016 – Background on sea level rise science, the regional perspective on sea level rise and also how sea level rise may specifically affect Carlsbad. Local Coastal Program update process introduced. (125 attendees)  October 2016 – Discussed sea level rise adaptation strategies and answered questions (60 attendees) o Outreach to affected property owners  June and September 2016 – Owners of property vulnerable to sea level rise were invited to share their concerns regarding sea level rise, how their properties have been impacted by recent storm events, what specific infrastructure and assets are of concern, and whether they have any plans to respond to sea level rise. More than 15 stakeholder interviews were held with interest groups and non-residential property owners, including public agencies, utilities and non-profit groups, and a survey was mailed to about 700 owners of residentially property. (250 completed surveys were returned) o Informational presentations to various community groups • Local Coastal Program outreach and engagement o Public workshop  October 2019 – Draft Local Coastal Program Land Use Plan introduced, community invited to review and comment on the draft plan. (83 attendees) Oct. 12, 2021 Item #7 Page 3 of 428 o Informational presentations  Staff presentations provided to various community groups, such as the Carlsbad Chamber of Commerce, Agua Hedionda Lagoon Foundation, Batiquitos Lagoon Foundation and the Beach Preservation Committee. • Email updates, social media o Social media and e-newsletters were used to let the community know about available information and opportunities to provide input, such as when the draft Local Coastal Program was available for public review and when public meetings were scheduled. (About 2,000 people have signed up for email updates) • Public hearings o Dec. 2, 2020, Jan. 6, 2021 and Jan. 13, 2021 – Planning Commission public hearing on the Local Coastal Program update. Over 14,000 postcards were mailed notifying all property owners in the Coastal Zone of the hearing date, time and how to participate. A similar postcard was mailed to all Coastal Zone property owners with information about the City Council’s public hearing on the draft plan. • Written public comments o The city received over 60 letters and emails from the community commenting on the draft Land Use Plan, not including the several thousand letters, emails and petitions requesting a Ponto park. o Comments received before the Dec. 2, 2020 Planning Commission hearing are addressed in the Planning Commission staff report (Exhibit 5), which divides the comments into two categories:  Comments regarding parks and open space in southwest Carlsbad, particularly on Ponto Planning Area F (Attachments 5 and 7 of staff report)  Comments regarding all other topics (Attachment 6) o Comment letters received before, during and after the December 2020 and January 2021 Planning Commission hearing are provided in Exhibit 11. Key policy changes The following sections provide an overview of the key policy changes that are being proposed as part of the Local Coastal Program update. (Additional information can be found in Exhibit 5.) Sea-level rise hazards As part of its work to develop sea-level rise policies, the city needed to identify areas of Carlsbad that are vulnerable to sea level rise hazards, such as flooding, inundation and bluff erosion, and develop policies to guide development within those vulnerable areas. Following the development and review of the Carlsbad Sea Level Rise Vulnerability Assessment (Appendix B of the draft Local Coastal Program Land Use Plan), along with Coastal Commission guidance, new sea level rise hazard policies have been developed and included in draft Local Coastal Program Land Use Plan Chapter 7 (LCP-7-P.7 – LCP-7-P.36). The guidance includes: o Requirements for sea level rise hazard analysis o Criteria on the siting of new development o Shoreline armoring Oct. 12, 2021 Item #7 Page 4 of 428 o Moving development away from hazards However, the draft policies do not fully align with Coastal Commission staff recommendations regarding certain sea-level rise policies, as detailed in the Coastal Commission issues section below. Scenic and Visual Resources Section 30251 of the state Coastal Act requires that new development be located and designed in a manner that protects views to and along the ocean and other scenic coastal areas, that new development minimize the alteration of natural landforms and that development is located and designed to be visually compatible with the character of surrounding areas. The city’s existing Local Coastal Program has some policies that address the protection of scenic and visual resources. The draft policies in Local Coastal Program Land Use Plan Chapter 5 (LCP-5-P.22 to LCP-5-P.32) include clearer direction on how to protect scenic resources and public views of scenic coastal areas, consistent with the Coastal Act and Coastal Commission guidance. Lower-cost visitor accommodations The program’s draft Land Use Plan includes new policies (LCP-3-P.18 to LCP-3-P.21) that provide a definition of “lower-cost” overnight accommodations and encourage both the protection and development of lower-cost visitor accommodations (LCP-3-P.14 and LCP-3- P.19). However, these draft policies do not fully align with Coastal Commission staff recommendations regarding the protection and provision of lower-cost visitor accommodations, as detailed below. Timeshares The Coastal Commission views timeshares and other limited-use overnight accommodations – such as condo-hotels and fractional ownership hotels – as residential uses rather than visitor-serving uses because they are not entirely available to the general public, available only to their owners. Therefore, the Coastal Commission does not support development of timeshares on land designated for visitor commercial uses, unless public access is ensured. The draft plan includes a policy (LCP-3-P.17) that would prohibit new timeshares or other limited-use overnight accommodations on land designated as Visitor Commercial (VC) on the land use map. During public review of the draft Land Use Plan, the topic of timeshares – or the potential prohibition of such uses – generated several comments objecting to a prohibition of timeshares. In response to public comments, staff recommend a revised policy that would permit timeshares subject to certain criteria, such as having a minimum number of units available to the general public, being run like a hotel and limiting the number of days that someone can stay. While Coastal Commission staff have not reviewed and commented on this revised policy, the Coastal Commission has approved this approach in other jurisdictions. Power plant and strawberry fields – land use and zoning designations As part of the 2015 General Plan update, the City Council approved changes to the land use and zoning map designations for the power plant and strawberry fields to designate the sites with the Visitor Commercial (VC ) land use and the Commercial Tourist (CT) zoning. Oct. 12, 2021 Item #7 Page 5 of 428 However, the Coastal Commission deferred its decision on these land use and zoning changes until the city provided more information on the need for visitor commercial uses. (See Exhibit 5 for more information about the proposed map changes and need for visitor commercial uses.) Staff recommend a modification to the land use/zoning map changes recommended by the Planning Commission on the San Diego Gas & Electric service center adjacent to the power plant site, as detailed in the section below titled Recommended modifications following Planning Commission approval. Poinsettia Shores Master Plan Planning Area F Poinsettia Shores Master Plan Planning Area F, an undeveloped area on the northeast corner of Carlsbad Boulevard and Avenida Encinas, is designated for residential and commercial use on the Local Coastal Program’s land use and zoning maps. The residential and commercial map designations were approved by the City Council in 2015 as part of the General Plan update, and subsequently approved by the Coastal Commission. Existing Local Coastal Program policy A.10, which relates to the West Batiquitos Lagoon/Sammis Properties segment, an area that includes Planning Area F, was not updated in 2015 and is inconsistent with the city’s residential and commercial land use and zoning map designations for the area. The proposed draft Local Coastal Program includes an update to policy A.10 to be consistent with the residential/commercial designations approved in 2015 (see draft LCP policy LCP-2-P.20.A). The topic that generated the majority of the public comments on the draft Local Coastal Program Land Use Plan is a request for a public park, “Ponto park,” to be developed on Planning Area F. On Jan. 26 and July 13, 2021, the City Council received informational staff reports on the topics of the allowed and planned land use of the site, the inconsistencies that need to be addressed, and the opportunities for open space and recreation in that area of the city. (Exhibits 9 and 10) Planning Commission Public hearing The Planning Commission held a public hearing that stretched over three dates, Dec. 2, 2020, Jan. 6, 2021 and Jan. 13, 2021, to consider the Local Coastal Program update. The following is a summary of the public comments read into the record during this hearing, which was held virtually due to the pandemic: • Over 200 people had their comments in support of a Ponto park read at the hearing. • A request for further community input on sea level rise management, protection of coastal habitats and accommodating recreational opportunities. • Concerns about impacts to existing neighborhoods and infrastructure. • A request to prioritize the use of non-chemical products for all city-owned spaces. • Request for more specificity on what may be prohibited for home maintenance. • Request for the scientific source material in sea level rise regulations. Oct. 12, 2021 Item #7 Page 6 of 428 • An attorney, speaking on behalf of the owner of Ponto Planning Area F, stated the Ponto site provides an opportunity for affordable housing and that the owner opposes downzoning of the site for open space or a park. • A request to change the description of the Agua Hedionda South Shore trail. • Support for the redevelopment of the Encina Power Station site as commercial space with small town and beach community values. Recommendation Following public comment, deliberation and discussion (Exhibits 6, 7 and 8), the Planning Commission unanimously recommended approval of the draft plan with revisions. Attachment A of Exhibit 1 identifies all of the recommended revisions to the draft plan and specifies whether each revision originated in response to public comments, or from staff or the Planning Commission. The revisions include the following: • Revising draft policy LCP-2-P.16.C to address the design of future redevelopment of the Encina Power Station site • Revising draft policy LCP-2-P.20.A to no longer require a future amendment to the Poinsettia Shores Master Plan, because an amendment to the master plan is now included as part of the Local Coastal Program update (Exhibit 2, Attachment B) • Adding a policy to Chapter 3 that requires the city to consider opportunities to create recreation areas as part of Carlsbad Boulevard realignment • Removing the discussion in Chapter 3 that describes the demand for visitor accommodations • Revising and deleting draft policies (LCP-3-P.14, 19, 20 and 21) that address lower-cost visitor accommodations, as described in the Coastal Commission issues section below • Replacing a policy that prohibits timeshares (LCP-3-P.17) with a policy that allows them, with certain criteria • Revising sea level rise hazard policies (LCP-7-P.8, 16, 21, and 22) to clarify what they are applicable to Modifications recommended following Planning Commission approval San Diego Gas & Electric Service Center – Local Coastal Program Land Use and Zoning On July 20, 2021, the City Council authorized staff to work with Brookfield Properties, NRG Energy and San Diego Gas & Electric on the possible relocation of SDG&E’s North Coast Service Center from its current location near the northeast corner of Carlsbad Boulevard and Cannon Road to a portion of the city-owned parking lot properties at The Shoppes at Carlsbad mall. This would help facilitate the transfer of the service center’s current site to the City of Carlsbad (Exhibit 12). As described above, the draft Local Coastal Program includes a proposal to change the land use and zoning map designations for the power plant site and the proposed map changes include the current SDG&E service center site. Because the outcome of the relocation effort may affect the ultimate land uses on the current SDG&E service center site, staff recommend that the city exclude the proposed Local Coastal Program land use and zoning Oct. 12, 2021 Item #7 Page 7 of 428 map changes from this update. Land use and zoning can be changed on the site as part of a future development proposal on the SDG&E site. (See Exhibit 13 for graphics showing the recommended revision to the Local Coastal Program land use and zoning maps.) This recommendation is included in the draft resolution and ordinance (Exhibits 1 and 2). Description of Carlsbad Boulevard Realignment The Planning Commission’s recommended revisions to the Local Coastal Program land use plan (Exhibit 1, Attachment A) includes adding information that describes potential opportunities that may result from realignment of Carlsbad Boulevard, including creation of additional recreation areas. On Sept. 14 and Sept. 21, 2021, the City Council received reports and provided direction on how to involve the community in creating a vision and guiding principles for the future of south Carlsbad Boulevard. To ensure that the Local Coastal Program does not conflict with the yet-to-be determined community vision for Carlsbad Boulevard, staff recommend revising the Planning Commission’s recommendation to be more general in the description of recreation opportunities, as shown below. • Add the following at end of the “Public Parks, Other Recreation Facilities, and Golf Courses” section (end of page 3-7 of draft Local Coastal Program Land Use Plan): The southbound lanes of Carlsbad Boulevard may be realigned with a shift to the east, which would provide an opportunity to create additional recreation areas (e.g., parks and other recreation facilities and amenities), and area for the state campground to expand or retreat inland to that could better adapt to sea level rise impacts. Sea level rise impacts are discussed further in Chapter 7, Coastal Hazards. • Add the following policy after draft policy LCP-3-P.13: Consider, as part of the evaluation of realigning the southern lanes of Carlsbad Boulevard inland, opportunities to create additional recreation areas (e.g., parks and other recreation facilities and amenities), and for the state campground to expand or retreat inland. Coastal Commission issues The draft Local Coastal Program Land Use Plan was drafted in consultation with local Coastal Commission staff and based on Coastal Commission guidance for local coastal program updates. Coastal Commission staff offered comments during the drafting process and most of their comments were addressed and are reflected in the draft Local Coastal Program Land Use Plan. There are, however, some specific issues that city staff and Coastal Commission staff do not agree on, the most significant of which are related to sea level rise hazard policies and lower-cost visitor accommodations policies. Additional information on these issues can be found in the Planning Commission staff report (Exhibit 5). Sea level rise policies Coastal Act Section 30235 allows construction of seawalls and other shoreline protective devices only when needed to protect “existing structures” and coastal dependent uses. The Coastal Act does not define “existing.” Coastal Commission staff recommends that the city define “existing,” in the context of Section 30235, as structures that existed prior to January 1, 1977 – the date the Coastal Act became effective. Today, there are about 100 structures, including residential and commercial uses, located on property fronting the ocean shoreline. Of those existing structures, Oct. 12, 2021 Item #7 Page 8 of 428 about 40 are estimated to have been constructed prior to 1977. Carlsbad Boulevard also existed prior to 1977. City staff recommends that “existing,” in the context of Coastal Act 30235, be defined using the date that the Local Coastal Program Land Use Plan is certified by the Coastal Commission. This is similar to how the city applies its new rules and regulations on new development and will allow for some flexibility in the ability to consider options to protect existing structures. Lower-cost visitor accommodations policies Coastal Act Section 30213 states that “lower cost visitor and recreational facilities shall be protected, encouraged, and, where feasible, provided…” To implement this Coastal Act section, Coastal Commission staff recommend that the city: protect existing low cost accommodations by prohibiting the loss of such units, unless mitigating the loss at a 1:1 ratio; require new hotel development to include 25% of the total rooms at a low cost rate or pay an in-lieu fee for 25% of the total units. The draft Local Coastal Program Land Use Plan includes a draft policy (LCP-3-P.21) that requires new development that results in a loss of existing lower-cost accommodations to mitigate the loss at a 1:1 ratio. However, after further consideration and in response to public comments, staff recommends deleting policy LCP-3-P.21 and revising other lower-cost accommodations policies (Exhibit 1, Attachment A) because: • The Coastal Act does not specify a minimum required number of lower-cost accommodations • An in-lieu fee program has not been analyzed and may conflict with the state’s Mitigation Fee Act, which sets rules on how local agency can impose and set various fees as a condition of approval of development projects • Based on the number of accommodations in Carlsbad, including lower-cost accommodations, it may be difficult to justify the need to mitigate the loss or lack of new lower-cost accommodations. Options Staff offer the following options for the City Council’s consideration: Option 1: Approve the proposed Local Coastal Program update, as recommended by the Planning Commission and staff, including updated policies that reflect residential and commercial use in Planning Area F of the Poinsettia Shores Master Plan. Pros • Achieves all objectives of the Local Coastal Program update (consistency with Coastal Act, Coastal Commission guidance and General Plan) Cons • Does not offer the City Council more time, if needed, to consider land use options for Planning Area F of the Poinsettia Shores Master Plan Oct. 12, 2021 Item #7 Page 9 of 428 Option 2: Approve the proposed Local Coastal Program update, as recommended by the Planning Commission, excluding changes to existing policies relative to Planning Area F of the Poinsettia Shores Master Plan. Pros • Achieves most objectives of the Local Coastal Program update; allows City Council more time to consider land use options for Planning Area F of the Poinsettia Shores Master Plan Cons • Does not achieve consistency with General Plan or Local Coastal Program on Planning Area F of the Poinsettia Shores Master Plan. • Local Coastal Program policy will remain inconsistent with Local Coastal Program and General Plan land use maps Option 3: Approve the proposed Local Coastal Program update with additional revisions added to the Planning Commission-recommended revisions to the draft Land Use Plan. Pros • Same as described in Options 1 and 2 • City Council could address concerns with the draft Local Coastal Program Land Use Plan not addressed by Planning Commission’s recommended revisions Cons • Same as described for Options 1 and 2 • Additional revisions to the draft plan may raise other concerns to be considered. Option 4: Take no action and request staff to return at a later date to allow more time for City Council consideration. Pros • Gives the City Council additional time to consider the item and to request additional information, if needed Cons • Delays approval of the Local Coastal Program update Option 5: Deny the draft Local Coastal Program Land Use Plan Pros • None identified by staff Cons • Existing Local Coastal Program policies would remain in effect and would remain inconsistent with Coastal Commission guidance and the General Plan, and would not adequately address important topics, such as sea level rise. • Future development would be impacted by uncertain and inconsistent land use policy, and lack of adequate policies that guide protection of coastal resources, such as policies that address scenic resources, water quality, and sea level rise hazards. • Grant funding expended for plan development, would result in lost work. Any effort to update the plan in the future would likely require a project restart, with additional consultant and staffing resources. Oct. 12, 2021 Item #7 Page 10 of 428 Staff and the Planning Commission recommend Option 1, approving the proposed Local Coastal Program update, as recommended by the Planning Commission and staff, including updated policies that reflect residential and commercial use in Planning Area F of the Poinsettia Shores Master Plan. Fiscal Analysis Adopting the recommended policies and standards do not have any impact on the fiscal year 2021-22 budget and current staff and funding resources are sufficient. However, in certain cases the city's implementation of the policies will require future funding, as listed below. Implementation of other associated policies may also result in future fiscal requirements, which are not listed below. Resource and fiscal impacts of policy requirements Requirement Frequency Estimated cost Funding source1 Update sea level rise vulnerability assessment Every 10 years2 $120,000 General Fund Develop, implement sea level rise hazard – shoreline development standards TBD 03 General Fund Prepare, maintain coastal armoring database Ongoing 03 General Fund Total future funding required $120,000 1 The city will make a concerted effort to seek other funding opportunities such as grant funding, but future grant opportunities aren’t known at this time. 2 The most recent Sea Level Rise Vulnerability Assessment was completed in 2017. 3 No additional costs are expected as current resources are expected to complete the tasks. Next Steps After adoption of the resolution and ordinance, staff will submit the Local Coastal Program update to the California Coastal Commission for review and approval. It is anticipated that the commission’s staff will identify areas of concerns with the Land Use Plan, not limited to just the comments they provided during the drafting of the plan. City staff will work with Coastal Commission staff to resolve any areas of concern before the Local Coastal Program is presented to the Coastal Commission at a public hearing. Any revisions to the city’s Local Coastal Program that the Coastal Commission approves during its public hearing process will be brought back to the City Council as suggested modifications. The City Council will be able to approve or reject the suggested modifications; however, they would need to be approved by the City Council before the Local Coastal Program is certified by the Coastal Commission and effective for use in the city. Environmental Evaluation (CEQA) The draft Local Coastal Program Land Use Plan, land use and zoning maps, Poinsettia Shores Master Plan and Village and Barrio Master Plan constitute, in part, the Carlsbad Local Coastal Program. In keeping with the California Environmental Quality Act, (Public Resources Code section 21000) and its implementing regulations (the CEQA Guidelines), and Article 14 of the California Code of Regulations section 15000, the proposed project is statutorily exempt because CEQA does not apply to activities and approvals by a local government as necessary for the preparation and Oct. 12, 2021 Item #7 Page 11 of 428 adoption of a local coastal program pursuant to the California Coastal Act (Public Resources Code Section 30000 et seq.). As provided by Public Resources Code section 21080.9 and CEQA Guidelines section 15265, the burden of CEQA compliance for local coastal programs is shifted from the city to the California Coastal Commission. Any Coastal Commission action to certify the draft Local Coastal Program Land Use Plan would meet the requirements of CEQA in accordance with CEQA Guidelines section 15251(f). Public Notification A notice for this public hearing was mailed to interested parties and all property owners in the Carlsbad Coastal Zone. This item was noticed in accordance with the Ralph M. Brown Act and available for viewing at least 72 hours prior to the meeting. Exhibits 1. City Council resolution A. Revisions to Draft Local Coastal Program Land Use Plan dated September 2019 B.

RECOMMENDED REVISIONS: DRAFT CHAPTER 1 - INTRODUCTION P Revise the last paragraph of Section 1.2, as follows: The Carlsbad Local Coastal Program Land Use Plan and General Plan both provide policies that guide the physical development of Carlsbad’s Coastal Zone; however, the General Plan is not a component of the Local Coastal Program. While they are two separate documents, some of the descriptive text and some of the policies are the same. Detailed discussion of Coastal Act requirements and goals is included only in this Local Coastal Program Land Use Plan, while issues that are not directly relevant to the Coastal Act are covered by the General Plan. If the policies of the General Plan conflict with the policies of this Local Coastal Program Land Use Plan, the policies of this Local Coastal Program Land Use Plan shall apply. RECOMMENDED REVISIONS: DRAFT CHAPTER 2 – LAND USE S Update Figure 2-1 Land Use Map, as necessary, to reflect any approved land use designation changes not reflected on the draft figure. P Revise the description of the Cannon Road Open Space Farming and Public Use Corridor (first paragraph on page 2-21 of draft Local Coastal Program Land Use Plan), as follows: Following voter approval of Proposition D, the city conducted a public planning process that occurred from November 2007 through June 2008, which resulted in the report titled “Creating a Community Vision for the Cannon Road Agriculture and Open Space (Prop D) Lands Final Report September 23, 2008.” This community vision was used to create City Council adopted the Cannon Road Agricultural/ and Open Space Zone, which establishes the permitted uses and standards for the corridor. to implement the proposition. In 2017, the Coastal Commission approved the Cannon Road Agricultural/Open Space Zone as part of the Local Coastal Program Implementation Plan (implementing the Open Space land use designation). However, the Coastal Commission’s approval applied the zone only to the area of the corridor located south of Cannon Road. To fully implement Proposition D, the city will need to seek Coastal Commission approval to apply the Cannon Road Agricultural/ Open Space Zone to the area of the corridor located north of Cannon Road. The new zone will become effective when the associated Local Coastal Program amendment is approved by the California Coastal Commission.

By RECOMMENDED REVISIONS: DRAFT CHAPTER 2 – LAND USE, CONT. PC Revise Figure 3-2 to add the existing Visitor Serving Commercial Site on the north shore of Agua Hedionda Lagoon: Oct. 12, 2021 Item #7 Page 21 of 428 Page 6 Revisions are recommended by staff (S) and Planning Commission (PC) and in response to public comment (P) Rec. By RECOMMENDED REVISIONS: DRAFT CHAPTER 3 – RECREATION AND VISITOR-SERVING USES, CONT. PC Delete the “Demand for Visitor Accommodations” section on pages 3-12 and 3-13: Demand for Visitor Accommodations The 2017 Carlsbad Visitor Profile (from San Diego Tourism Authority) shows that over a 12-year period, from 2005 to 2017, the number of visitors to Carlsbad increased a total of 50.8 percent, an average annual increase of 4.4 percent (this information accounts for a decrease in number of visitors during the years of economic recession, 2008 – 2009). The overall increase in the number of visitors (some of which are day visitors, and some are overnight visitors) results in an increased demand for hotel rooms or other overnight accommodations. A report titled, “Tourism Economics San Diego Travel Forecast July 2018” (prepared for San Diego Tourism Authority), forecasts the annual increase in hotel room demand in San Diego through the year 2023. The local Carlsbad tourism agency, Visit Carlsbad, utilizes this report to forecast hotel demand in Carlsbad. According to the report, hotel demand is estimated to increase approximately 2 percent each year from 2019 to 2023. Applying the forecasted demand to Carlsbad compared to the number of existing hotel rooms in Carlsbad, as stated above, an additional 500 hotel rooms would be needed in Carlsbad (approximately 100 additional rooms per year from 2019 to 2023) to meet the forecasted annual 2-percent increase in hotel demand (assuming the existing number of hotel rooms meets the current demand). However, by 2023, more than 500 hotel rooms may be needed in Carlsbad due to existing unmet demand. Based on hotel data for the years 2012 to 2017, there is a high level of consistent room night demand and unmet seasonal demand, which results in the loss of overnight visitors to non-Carlsbad hotel markets (i.e., the demand for hotel rooms exceeds the supply of hotel rooms in Carlsbad, particularly in the high tourist season). Also, from 2012 to 2017, hotel demand increase in Carlsbad was consistent with the increase in supply over that five-year period, which indicates unmet hotel demand in the market. Hotel occupancy in Carlsbad also indicates a demand for more hotel rooms. From April 2017 to March 2018, occupancy rates in Carlsbad ranged from a monthly average of 65 percent to 90 percent. Eighty to 90 percent average monthly occupancy levels occurred in April, June, July, and August 2017, and March 2018; these 80- to 90-percent occupancy levels suggest that there is a significant opportunity for new hotels to accommodate unmet hotel demand during those high demand months. To accommodate the existing and future demand for more hotel rooms, the city should identify and designate land where new hotels and other visitor-serving uses can be developed. The actual number of additional rooms that are ultimately built in the city will depend on future market conditions and the amount of land designated for hotel uses.

By RECOMMENDED REVISIONS: DRAFT CHAPTER 3 – RECREATION AND VISITOR-SERVING USES, CONT. P Revise draft policy LCP-3-P.12, as follows: LCP-3-P.12 Work with the California Department of Parks and Recreation to enhance public access and recreation, public access, visitor-commercial services, and activity in along the Carlsbad Boulevard coastal corridor. Principal objectives should be to create additional recreational opportunities, public waterfront amenities and services (e.g., restrooms and showers), including as well as modernization and expansion of the campgrounds to serve as lower-cost visitor and recreational facilities; improve coastal access for all; conserve coastal resources; and enhance public safety, including addressing threats to the campground from bluff erosion P Add the following policy after draft policy LCP-3-P.13: Consider, as part of the evaluation of realigning the southern lanes of Carlsbad Boulevard inland, opportunities to create additional recreation areas (e.g., parks and other recreation facilities and amenities), and for the state campground to expand or retreat inland. S Revise draft policy LCP-3-P.14 and delete draft policies LCP-3-P.19, LCP-3-P.20 and LCP-3-P.21, as follows: LCP-3-P.14 Protect, encourage, and, where feasible, provide for development of new (and retention of existing) lower-cost visitor overnight accommodations and recreation facilities, such as through regulatory incentives (e.g., development standards modifications). Consider amenities that reduce the cost of stay when evaluating the affordability of any new or redeveloped overnight visitor accommodations; and encourage and support developments that provide public recreational opportunities within the Coastal Zone [related to Coastal Act Section 30213]. … LCP-3-P.19 Encourage development of lower-cost overnight accommodations, such as through regulatory incentives (e.g., development standards modifications). LCP-3-P.20 Require new development and redevelopment proposals, which propose to remove, replace, or remodel existing accommodations, to provide data from Smith Travel Research that identifies whether the accommodations to be removed, replaced, or remodeled are “lower- cost” as defined by policy LCP-3-P.18. The data from Smith Travel Research shall be the most recent available at the time of development application submittal. LCP-3-P.21 Require new development and redevelopment proposals that propose to remove, replace, or remodel existing “lower-cost” accommodations to mitigate the loss of any existing “lower- cost” accommodations with new lower-cost visitor accommodations at a 1:1 ratio and be subject to the following: A. Mitigation shall prioritize providing for lower-cost overnight accommodations on-site, where possible. B. If providing lower-cost overnight accommodations on-site is not feasible, according to a feasibility analysis submitted by the applicant and accepted by the city, then 1:1 replacement off-site within the Carlsbad Coastal Zone shall be required. These off-site overnight accommodations shall be completed and ready for use prior to occupancy of the new development.

By RECOMMENDED REVISIONS: DRAFT CHAPTER 4 – COASTAL ACCESS, CONT. P Add the following to the end of draft Section 4.4 (end of page 4-30 of draft Local Coastal Program Land Use Plan): Reduce Parking Demand In addition to providing off-street and on-street public parking spaces, implementing methods to reduce parking demand will assist in providing public access to the coast. One method to reduce parking demand is transportation demand management (TDM). TDM consists of strategies to reduce the demand for the single-occupant vehicle. Common TDM strategies include carpool programs, car-sharing and bike-sharing programs, flexible work hours, telecommute provisions, shuttle services to nearby transit stations, installation of bicycle facilities (lockers, racks, lanes, showers at employment areas, etc.), or other measures that would reduce the demand to drive; thereby, reducing the demand for parking. P Revise policy 4-P.26, as follows: LCP-4-P.26 Ensure that the design, location, construction, and operation of trails and bikeways avoids or minimizes adverse impacts to coastal resources, including sensitive habitats and species, and agriculture. For example, the design and operation of the future trails on the north side of Cannon Road, south of Agua Hedionda Lagoon (as shown on Figure 4-2), shall avoid or minimize impacts to the existing agriculture on the property. S Revise draft policy 4-P.37, as follows LCP-P.37 Identify opportunities to provide additional public parking near beach areas. P Add the following policies (to follow draft policy LCP-4-P.40): Support transportation demand management (TDM) strategies to reduce parking demand related to single-occupancy vehicle trips and to promote walking, biking, transit use, carpooling, etc. Apply the Village and Barrio Master Plan for additional policies and provisions related to parking management strategies in the master plan area. Oct. 12, 2021 Item #7 Page 25 of 428 Page 10 Revisions are recommended by staff (S) and Planning Commission (PC) and in response to public comment (P) Rec. By RECOMMENDED REVISIONS: DRAFT CHAPTER 5 – AGRICULTURAL, CULTURAL AND SCENIC RESOURCES P Revise the second paragraph of the description of “Coastal Act Section 30171.5 – Statutory Program” on page 5-7 of draft Local Coastal Program Land Use Plan, as follows: The statutory program requires payment of a fee to mitigate the conversion of agricultural lands and specifies that the fee can be used only for restoration of Batiquitos Lagoon, an interpretive center at Buena Vista Lagoon, access to public beaches, and other projects that enhance the use of natural resources, including open field cultivated floriculture (refer to Section 5.1 for the full text of Coastal Act Section 30171.5). PC Add the follow paragraph at the end of page 5-26: While not listed as Historic Resources, there are many cultural resources that add to the charm and character of the Village and Barrio area, some of those include: Twin Inns, the structures in McGee Park, the Pizza Port building, the Army Navy Academy, and the bungalows throughout the area, just to name a few. P Revise policies LCP-5-P.2 and 5-P.3, as follows: LCP-5-P.2 Recognize the important value of agriculture and Ssupport the continuation of existing agriculture by minimizing conflicts with urban uses; such as by requiring new adjacent development to utilize buffers, vegetation, and other site design features that minimize impacts on the agricultural use; and by requiring farm operators to utilize methods to prevent dust and pesticide impacts on adjacent uses [related to Coastal Act Section 30241]. LCP-5-P.3 Support and encourage the continuation of agriculture within the Cannon Road Open Space, Farming and Public Use Corridor, and other areas by utilizing methods and resources to reduce the financial burdens on agricultural land, not only to prevent premature development but also to encourage its continued use for agricultural purposes. For example, consider construction of public facility improvements, such as drainage improvements, which are designed to support the continuation of agriculture. P Revise policy LCP-5-P.17, as follows: LCP-5-P.17 Ensure that the determination of the significance of cultural or tribal cultural resources, and the development and implementation of any appropriate treatment measures and procedures, is conducted by a qualified archaeologist and, in the case of tribal cultural resources, in consultation with interestedculturally- and geographically-affiliated California Native American Tribes. All Native American human remains and associated grave goods shall be returned to their most likely descendent and repatriated. The final disposition of tribal cultural resources not directly associated with Native American graves shall be negotiated during consultation with interested Tribes in accordance with the California Environmental Quality Act, Public Resources Code Section 21084.3, and any other applicable laws and regulations.

Oct. 12, 2021 Item #7 Page 27 of 428 Page 12 Revisions are recommended by staff (S) and Planning Commission (PC) and in response to public comment (P) Rec. By RECOMMENDED REVISIONS: DRAFT CHAPTER 6 – ENVIRONMENTALLY SENSITIVE HABITAT AREAS AND WATER QUALITY P Add the following at the end of Section 6.2 on page 6-14 of draft Local Coastal Program Land Use Plan: Impacts of Beach Grooming on Beach Ecosystem “Beach wrack” is an important part of the marine ecosystem. “Beach wrack” refers to the mounds of seaweed and other loose organic material that is brought ashore and accumulates by the natural processes of tides and waves. While these mounds may appear to beach visitors as unsightly debris, wrack is an important nutrient source for the beach ecosystem, in that it provides micro-habitat for a variety of organisms, supports the prey of many marine and terrestrial invertebrates and shorebirds, and contributes to the establishment of coastal strand and incipient dune habitat. Regular grooming of sandy beaches can destroy the wrack and degrade the near shore habitat. Research has shown that groomed beaches have lower invertebrate species richness, abundance and biomass and supports fewer birds in absolute numbers and species diversity. Beach grooming can negatively impact sensitive shorebird species, such as the western snowy plover and the California least tern, that forage and nest on the open beach. The western snowy plover establishes nests just above the wrack line in the upper beach and coastal strand zone. These nests are very exposed and vulnerable to disturbance and predation. The California least tern breeds on exposed tidal flats, beaches and bays of the Pacific Ocean and is vulnerable to predators, natural disasters and human disturbance. Beach grooming not only removes potential plover and tern nest material, but can also flatten the subtle topographic depressions that these birds use to nest in. Beach grooming can also negatively impact California grunion, which are a species of fish with a very unique mating ritual. Grunion come ashore in the spring and summer to reproduce during particularly high night-time tides. Female grunion dig their tails into the sand and lay their eggs. For the next ten days or so grunion eggs remain buried in the sand until the next high tide when the eggs hatch and young grunion are washed out to sea. If beach grooming occurs while grunion eggs are buried, all the eggs may be destroyed. PC On Page 6-15, revise the first paragraph of the “Surface Water Quality” section, as follows: Surface Water Quality Impacts to the Carlsbad hydrologic unit include surface water quality degradation, sewage spills, sedimentation, habitat degradation and loss, invasive species, and eutrophication (i.e., excessive nutrients in a body of water, usually resulting from runoff from land, which causes a dense growth of plant life and death of animal life from lack of oxygen). Pollutant conditions in the Carlsbad hydrologic unit include bacterial indicators, eutrophic conditions, nutrients, sediments, sulfates, nitrates, and phosphates. The sources of these pollutants are varied and include urban runoff, agricultural runoff, sewage spills, livestock/domestic animals, and other natural sources. Key water quality issues in the city’s principal surface water bodies are described below. The water quality issues described below are addressed through regional programs that focus on improving existing water quality conditions.

By RECOMMENDED REVISIONS: DRAFT CHAPTER 6 – ENVIRONMENTALLY SENSITIVE HABITAT AREAS AND WATER QUALITY P Revise the first paragraph of the description of Buena Vista Lagoon starting on page 6-15 of draft Local Coastal Program Land Use Plan, as follows: Buena Vista Lagoon is a 220-acre freshwater lagoon managed as an ecological reserve by the California Department of Fish and Wildlife. The principal water quality issues in the watershed relate to tThe lagoon, which is identified on the 2012 California 2014-2016 Clean Water Act (CWA) Section 303(d) lList of Impaired Waters for as impaired due to the presence of pollutants (nutrients, indicator bacteria, sediment toxicity, and sedimentation/siltation). Waters on the Section 303(d) list are those that do not meet water quality standards and parameters for pollutants. Buena Vista Creek, which feeds into the lagoon, is also listed as impaired for sediment toxicity, benthic community effects, bifenthrin, and selenium. The City of Vista has installed a series of check dams and a detention basin to assist in the removal of sediments traveling through Buena Vista Creek. P Revise the last paragraph of the description of Buena Vista Lagoon on page 6-16 of draft Local Coastal Program Land Use Plan, as follows: In July 2012, the San Diego Association of Governments (SANDAG) began an environmental review process for the Buena Vista Lagoon Enhancement Project, which includeds evaluation of three enhancement alternatives (freshwater, saltwater, and a saltwater/freshwater hybrid regime) and a no project alternative. In July 2019On May 22, 2020, SANDAG, adopted a resolution to accept the saltwater alternative, which will allow the Buena Vista Lagoon to connect directly with ocean waters to flush out sediments. property owners and other stakeholders agreed to pursue a modified hybrid saltwater enhancement option. P Revise the first paragraph of the description of Agua Hedionda Lagoon on page 6-16 of draft Local Coastal Program Land Use Plan, as follows: Agua Hedionda Lagoon encompasses three interconnected lagoons, divided by Interstate 5 and a railroad bridge. The Agua Hedionda Ecological Reserve was acquired in 2000 by the California Department of Fish and Wildlife and consists of 186 acres of wetland at the eastern end of the lagoon. Although Agua Hedionda Lagoon is not listed as impaired on the California 2014-2016 CWA Section 303(d) List of Impaired Waters for toxicity., Sources are listed as unknown. Agua Hedionda Creek, which feeds into the lagoon, is listed as impaired on the 2012 California 2014- 2016 Clean Water ActCWA Section 303(d) List of Impaired Waters list as impaired for benthic community effects, indicator bacteria, enterococcus, fecal coliform,malathion manganese, bifenthrin, chlorpyrifos, cypermethrin, phosphorus, selenium, total dissolved solids, total nitrogen as N, and toxicity.

PC Add “Environmentally Sensitive Habitat Area (ESHA)” policy: Ensure large scale beach maintenance activities avoid adverse impacts to the beach ecosystem, including beach wrack and near shore habitat during the spring/summer nesting season (April- August). Organized beach grooming should be avoided to the extent feasible, but would be allowed to decrease impacts of flying insect populations and large beach displacement areas on beachgoers. Alternative beach maintenance activities, such as manual beach cleaning, should be restricted when sensitive species are present on the beach (e.g., grunion, western snowy plover and least tern); when sensitive species are present, limit beach maintenance to areas located more than 10 feet landward of the beach wrack habitat line or mean high tide line, whichever is farthest landward. P Add the following “Marine and Coastal Water Quality” policy, as follows: Support the Buena Vista Lagoon Enhancement Project and enter into a project agreement with San Diego Association of Governments (SANDAG), the City of Oceanside, the California Department of Fish and Wildlife, and other affected property owners.

aquaculture facilities; priority Oceanfront land that is suitable for coastal dependent aquaculture shall be protected for that use, and proposals for aquaculture facilities located on those sites shall be given priority, except over other coastal dependent developments or uses. Section 30250 Location; existing developed area (a) New residential, commercial, or industrial development, except as otherwise provided in this division, shall be located within, contiguous with, or in close proximity to, existing developed areas able to accommodate it or, where such areas are not able to accommodate it, in other areas with adequate public services and where it will not have significant adverse effects, either individually or cumulatively, on coastal resources. In addition, land divisions, other than leases for agricultural uses, outside existing developed areas shall be permitted only where 50 percent of the usable parcels in the area have been developed and the created parcels would be no smaller than the average size of surrounding parcels. (b) Where feasible, new hazardous industrial development shall be located away from existing developed areas. (c) Visitor-serving facilities that cannot feasibly be located in existing developed areas shall be located in existing isolated developments or at selected points of attraction for visitors. Section 30254 Public works facilities New or expanded public works facilities shall be designed and limited to accommodate needs generated by development or uses permitted consistent with the provisions of this division; provided, however, that it is the intent of the Legislature that State Highway Route 1 in rural areas of the coastal zone remain a scenic two-lane road. Special districts shall not be formed or expanded except where assessment for, and provision of, the service would not induce new development inconsistent with this division. Where existing or planned public works facilities can accommodate only a limited amount of new development, services to coastal-dependent land use, essential public services and basic industries vital to the economic health of the region, state, or nation, public recreation, commercial recreation, and visitor-serving land uses shall not be precluded by other development. Section 30255 Priority of coastal-dependent developments Coastal-dependent developments shall have priority over other developments on or near the shoreline. Except as provided elsewhere in this division, coastal-dependent developments shall not be sited in a wetland. When appropriate, coastal-related developments should be accommodated within reasonable proximity to the coastal- dependent uses they support. Oct. 12, 2021 Item #7 Page 92 of 428 PUBLIC REVIEW DRAFT 2019 2-4 Section 30260 Location or expansion [industrial development] Coastal-dependent industrial facilities shall be encouraged to locate or expand within existing sites and shall be permitted reasonable long-term growth where consistent with this division. However, where new or expanded coastal-dependent industrial facilities cannot feasibly be accommodated consistent with other policies of this division, they may nonetheless be permitted in accordance with this section and Sections 30261 and 30262 if (1) alternative locations are infeasible or more environmentally damaging; (2) to do otherwise would adversely affect the public welfare; and (3) adverse environmental effects are mitigated to the maximum extent feasible. Section 30264 Thermal electric generating plants Notwithstanding any other provision of this division except subdivisions (b) and (c) of Section 30413, new or expanded thermal electric generating plants may be constructed in the coastal zone if the proposed coastal site has been determined by the State Energy Resources Conservation and Development Commission to have greater relative merit pursuant to the provisions of Section 25516.1 than available alternative sites and related facilities for an applicant’s service area which have been determined to be acceptable pursuant to the provisions of Section 25516.

The commission shall not: (1) require that overnight room rentals be fixed at an amount certain for any privately owned and operated hotel, motel, or other similar visitor-serving facility located on either public or private lands; or (2) establish or approve any method for the identification of low or moderate income persons for the purpose of determining eligibility for overnight room rentals in any such facilities. Section 30220 Protection of certain water-oriented activities Coastal areas suited for water-oriented recreational activities that cannot readily be provided at inland water areas shall be protected for such uses. Section 30221 Oceanfront land; protection for recreational use and development Oceanfront land suitable for recreational use shall be protected for recreational use and development unless present and foreseeable future demand for public or commercial recreational activities that could be accommodated on the property is already adequately provided for in the area. Section 30222 Private lands; priority of development purposes The use of private lands suitable for visitor-serving commercial recreational facilities designed to enhance public opportunities for coastal recreation shall have priority over private residential, general industrial, or general commercial development, but not over agriculture or coastal-dependent industry. Section 30223 Upland areas Upland areas necessary to support coastal recreational uses shall be reserved for such uses, where feasible. Section 30224 Recreational boating use; encouragement; facilities Increased recreational boating use of coastal waters shall be encouraged, in accordance with this division, by developing dry storage areas, increasing public launching facilities, providing additional berthing space in existing harbors, limiting non-water-dependent land uses that congest access corridors and preclude boating support facilities, providing harbors of refuge, and by providing for new boating facilities in natural harbors, new protected water areas, and in areas dredged from dry land. Section 30234 Commercial fishing and recreational boating facilities Facilities serving the commercial fishing and recreational boating industries shall be protected and, where feasible, upgraded. Existing commercial fishing and recreational boating harbor space shall not be reduced unless the demand for those facilities no longer exists or adequate substitute space has been provided. Proposed recreational boating facilities shall, where feasible, be designed and located in such a fashion as not to interfere with the needs of the commercial fishing industry.

Section 30211 Development not to interfere with access Development shall not interfere with the public's right of access to the sea where acquired through use or legislative authorization, including, but not limited to, the use of dry sand and rocky coastal beaches to the first line of terrestrial vegetation. Section 30212 New development projects (a) Public access from the nearest public roadway to the shoreline and along the coast shall be provided in new development projects except where: (1) it is inconsistent with public safety, military security needs, or the protection of fragile coastal resources, (2) adequate access exists nearby, or, (3) agriculture would be adversely affected. Dedicated accessway shall not be required to be opened to public use until a public agency or private association agrees to accept responsibility for maintenance and liability of the accessway. (b) For purposes of this section [Article 2 of the Coastal Act], "new development" does not include: (1) Replacement of any structure pursuant to the provisions of subdivision (g) of Section 30610. (2) The demolition and reconstruction of a single-family residence; provided, that the reconstructed residence shall not exceed either the floor area, height or bulk of the former structure by more than 10 percent, and that the reconstructed residence shall be sited in the same location on the affected property as the former structure. (3) Improvements to any structure which do not change the intensity of its use, which do not increase either the floor area, height, or bulk of the structure by more than 10 percent, which do not block or impede public access, and which do not result in a seaward encroachment by the structure. (4) The reconstruction or repair of any seawall; provided, however, that the reconstructed or repaired seawall is not a seaward of the location of the former structure. (5) Any repair or maintenance activity for which the commission has determined, pursuant to Section 30610, that a coastal development permit will be required unless the commission determines that the activity will have an adverse impact on lateral public access along the beach. As used in this subdivision "bulk" means total interior cubic volume as measured from the exterior surface of the structure. (c) Nothing in this division shall restrict public access nor shall it excuse the performance of duties and responsibilities of public agencies which are required by Sections 66478.1 to 66478.14, inclusive, of the Government Code and by Section 4 of Article X of the California Constitution. Section 30212.5 Public facilities; distribution Wherever appropriate and feasible, public facilities, including parking areas or facilities, shall be distributed throughout an area so as to mitigate against the impacts, social and otherwise, of overcrowding or overuse by the public of any single area. Oct. 12, 2021 Item #7 Page 142 of 428 PUBLIC REVIEW DRAFT 2019 4-4 Section 30214 Implementation of public access policies; legislative intent (a) The public access policies of this article [Article 2 of the Coastal Act] shall be implemented in a manner that takes into account the need to regulate the time, place, and manner of public access depending on the facts and circumstances in each case including, but not limited to, the following: (1) Topographic and geologic site characteristics. (2) The capacity of the site to sustain use and at what level of intensity. (3) The appropriateness of limiting public access to the right to pass and repass depending on such factors as the fragility of the natural resources in the area and the proximity of the access area to adjacent residential uses. (4) The need to provide for the management of access areas so as to protect the privacy of adjacent property owners and to protect the aesthetic values of the area by providing for the collection of litter. (b) It is the intent of the Legislature that the public access policies of this article [Article 2 of the Coastal Act] be carried out in a reasonable manner that considers the equities and that balances the rights of the individual property owner with the public's constitutional right of access pursuant to Section 4 of Article X of the California Constitution. Nothing in this section or any amendment thereto shall be construed as a limitation on the rights guaranteed to the public under Section 4 of Article X of the California Constitution. (c) In carrying out the public access policies of this article [Article 2 of the Coastal Act], the commission and any other responsible public agency shall consider and encourage the utilization of innovative access management techniques, including, but not limited to, agreements with private organizations which would minimize management costs and encourage the use of volunteer programs. Section 30252(1) to (5) Maintenance and enhancement of public access The location and amount of new development should maintain and enhance public access to the coast by (1) facilitating the provision or extension of transit service, (2) providing commercial facilities within or adjoining residential development or in other areas that will minimize the use of coastal access roads, (3) providing nonautomobile circulation within the development, (4) providing adequate parking facilities or providing substitute means of serving the development with public transportation, (5) assuring the potential for public transit for high intensity uses such as high-rise office buildings… Oct. 12, 2021 Item #7 Page 143 of 428 CARLSBAD LOCAL COASTAL PROGRAM LAND USE PLAN 4-5 4.2 Vertical and Lateral Pedestrian Coastal Access Vertical Pedestrian Access to the Coast Lateral Pedestrian Access along the Coast Oct. 12, 2021 Item #7 Page 144 of 428 PUBLIC REVIEW DRAFT 2019 4-6 Oct. 12, 2021 Item #7 Page 145 of 428 J¶J¶J¶J¶J¶J¶J¶J¶J¶J¶J¶J¶J¶J¶J¶J¶J¶J¶J¶City ofOceanside ?©!"^$ J¶¶¶Aqua Hedion da La goon BuenaVista Lagoon J¶¶¶¶¶ ¶ ¶¶¶ CHINQ U A PIN AV EADAMS ST MARRON RD TAMA R A CK AVE C A RLSBAD V ILLA G ED R PARKDRMAGN O L IA AVEJEFFERSON STOCE AN S T CARL S B ADB L V DSource: Michael Baker International, 2016;

Section 30171.5 City of Carlsbad; local coastal program; mitigation fee for development on non-prime agricultural lands; priorities (a) The amount of the mitigation fee for development on nonprime agricultural lands in the coastal zone in the City of Carlsbad that lie outside of the areas described in subdivision (f) of Section 30170 and subdivision (b) of Section 30171 shall be determined in the applicable segment of the local coastal program of the City of Carlsbad, but shall not be less than five thousand dollars ($5,000), nor more than ten thousand dollars ($10,000), per acre. All mitigation fees collected under this section shall be deposited in the State Coastal Conservancy Fund. (b) All mitigation fees collected pursuant to this section are hereby appropriated to, and shall be expended by, the State Coastal Conservancy in the following order of priority: (1) Restoration of natural resources and wildlife habitat in Batiquitos Lagoon. (2) Development of an interpretive center at Buena Vista Lagoon. (3) Provision of access to public beaches in the City of Carlsbad. (4) Any other project or activity benefiting or enhancing the use of natural resources, including open field cultivated floriculture, in the coastal zone in the City of Carlsbad that is provided for in the local coastal program of the City of Carlsbad. (c) The State Coastal Conservancy may establish a special account in the State Coastal Conservancy Fund and deposit mitigation fees collected pursuant to this section in the special account. Any interest accruing on that money in the special account shall be expended pursuant to subdivision (b). (d) Not less than 50 percent of collected and bonded mitigation fees shall be expended for the purpose specified in paragraph (1) of subdivision (b). (e) Other than to mitigate the agricultural conversion impacts for which they are collected, none of the mitigation fees collected pursuant to this section shall be used for elements of a project which cause that project to be in compliance with this division or to mitigate a project which would otherwise be inconsistent with this division. When reviewing a potential project for consistency with this subdivision, the State Coastal Conservancy shall consult with the commission. Oct. 12, 2021 Item #7 Page 186 of 428 PUBLIC REVIEW DRAFT 2019 5-4 Section 30241 Prime agricultural land; maintenance in agricultural production The maximum amount of prime agricultural land shall be maintained in agricultural production to assure the protection of the areas’ agricultural economy, and conflicts shall be minimized between agricultural and urban land uses through all of the following: (a) By establishing stable boundaries separating urban and rural areas, including, where necessary, clearly defined buffer areas to minimize conflicts between agricultural and urban land uses. (b) By limiting conversions of agricultural lands around the periphery of urban areas to the lands where the viability of existing agricultural use is already severely limited by conflicts with urban uses or where the conversion of the lands would complete a logical and viable neighborhood and contribute to the establishment of a stable limit to urban development. (c) By permitting the conversion of agricultural land surrounded by urban uses where the conversion of the land would be consistent with Section 30250. (d) By developing available lands not suited for agriculture prior to the conversion of agricultural lands. (e) By assuring public service and facility expansions and nonagricultural development do not impair agricultural viability either through increased assessment costs or degraded air and water quality. (f) By assuring that all divisions of prime agricultural lands, except those conversions approved pursuant to subdivision (b), and all development adjacent to prime agricultural lands shall not diminish the productivity of such prime agricultural lands. Section 30241.5 Agricultural land; determination of viability of uses; economic feasibility evaluation (a) If the viability of existing agricultural uses is an issue pursuant to subdivision (b) of Section 30241 as to any local coastal program or amendment to any certified local coastal program submitted for review and approval under this division, the determination of "viability" shall include, but not be limited to, consideration of an economic feasibility evaluation containing at least both of the following elements: (1) An analysis of the gross revenue from the agricultural products grown in the area for the five years immediately preceding the date of the filing of a proposed local coastal program or an amendment to any local coastal program. (2) An analysis of the operational expenses, excluding the cost of land, associated with the production of the agricultural products grown in the area for the five years immediately preceding the date of the filing of a proposed local coastal program or an amendment to any local coastal program. For purposes of this subdivision, "area" means a geographic area of sufficient size to provide an accurate evaluation of the economic feasibility of agricultural uses for those lands included in the local coastal program or in the proposed amendment to a certified local coastal program. (b) The economic feasibility evaluation required by subdivision (a) shall be submitted to the commission, by the local government, as part of its submittal of a local coastal program or an amendment to any local coastal program. If the local government determines that it does not have the staff with the necessary expertise to conduct the economic feasibility evaluation, the evaluation may be conducted under agreement with the local government by a consultant selected jointly by local government and the executive director of the commission. Oct. 12, 2021 Item #7 Page 187 of 428 CARLSBAD LOCAL COASTAL PROGRAM LAND USE PLAN 5-5 Section 30242 Lands suitable for agricultural use; conversion All other lands suitable for agricultural use shall not be converted to nonagricultural uses unless (l) continued or renewed agricultural use is not feasible, or (2) such conversion would preserve prime agricultural land or concentrate development consistent with Section 30250. Any such permitted conversion shall be compatible with continued agricultural use on surrounding lands. Section 30244 Archaeological or paleontological resources Where development would adversely impact archaeological or paleontological resources as identified by the State Historic Preservation Officer, reasonable mitigation measures shall be required. Section 30251 Scenic and visual qualities The scenic and visual qualities of coastal areas shall be considered and protected as a resource of public importance.

Section 30121 Wetland "Wetland" means lands within the coastal zone which may be covered periodically or permanently with shallow water and include saltwater marshes, freshwater marshes, open or closed brackish water marshes, swamps, mudflats, and fens. Section 30230 Marine resources; maintenance Marine resources shall be maintained, enhanced, and where feasible, restored. Special protection shall be given to areas and species of special biological or economic significance. Uses of the marine environment shall be carried out in a manner that will sustain the biological productivity of coastal waters and that will maintain healthy populations of all species of marine organisms adequate for long-term commercial, recreational, scientific, and educational purposes. Section 30231 Biological productivity; water quality The biological productivity and the quality of coastal waters, streams, wetlands, estuaries, and lakes appropriate to maintain optimum populations of marine organisms and for the protection of human health shall be maintained and, where feasible, restored through, among other means, minimizing adverse effects of waste water discharges and entrainment, controlling runoff, preventing depletion of ground water supplies and substantial interference with surface waterflow, encouraging waste water reclamation, maintaining natural vegetation buffer areas that protect riparian habitats, and minimizing alteration of natural streams. Section 30233 Diking, filling or dredging; continued movement of sediment and nutrients (a) The diking, filling, or dredging of open coastal waters, wetlands, estuaries, and lakes shall be permitted in accordance with other applicable provisions of this division, where there is no feasible less environmentally damaging alternative, and where feasible mitigation measures have been provided to minimize adverse environmental effects, and shall be limited to the following: (1) New or expanded port, energy, and coastal-dependent industrial facilities, including commercial fishing facilities. (2) Maintaining existing, or restoring previously dredged, depths in existing navigational channels, turning basins, vessel berthing and mooring areas, and boat launching ramps. (3) In open coastal waters, other than wetlands, including streams, estuaries, and lakes, new or expanded boating facilities and the placement of structural pilings for public recreational piers that provide public access and recreational opportunities. (4) Incidental public service purposes, including but not limited to, burying cables and pipes or inspection of piers and maintenance of existing intake and outfall lines. Oct. 12, 2021 Item #7 Page 232 of 428 PUBLIC REVIEW DRAFT 2019 6-4 (5) Mineral extraction, including sand for restoring beaches, except in environmentally sensitive areas. (6) Restoration purposes. (7) Nature study, aquaculture, or similar resource dependent activities. b) Dredging and spoils disposal shall be planned and carried out to avoid significant disruption to marine and wildlife habitats and water circulation. Dredge spoils suitable for beach replenishment should be transported for these purposes to appropriate beaches or into suitable longshore current systems. c) In addition to the other provisions of this section, diking, filling, or dredging in existing estuaries and wetlands shall maintain or enhance the functional capacity of the wetland or estuary. Any alteration of coastal wetlands identified by the Department of Fish and Game, including, but not limited to, the 19 coastal wetlands identified in its report entitled, "Acquisition Priorities for the Coastal Wetlands of California", shall be limited to very minor incidental public facilities, restorative measures, nature study, commercial fishing facilities in Bodega Bay, and development in already developed parts of south San Diego Bay, if otherwise in accordance with this division. For the purposes of this section, "commercial fishing facilities in Bodega Bay" means that not less than 80 percent of all boating facilities proposed to be developed or improved, where the improvement would create additional berths in Bodega Bay, shall be designed and used for commercial fishing activities. d) Erosion control and flood control facilities constructed on watercourses can impede the movement of sediment and nutrients that would otherwise be carried by storm runoff into coastal waters. To facilitate the continued delivery of these sediments to the littoral zone, whenever feasible, the material removed from these facilities may be placed at appropriate points on the shoreline in accordance with other applicable provisions of this division, where feasible mitigation measures have been provided to minimize adverse environmental effects. Aspects that shall be considered before issuing a coastal development permit for these purposes are the method of placement, time of year of placement, and sensitivity of the placement area. Section 30240 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. Section 30250(a) Location; existing developed area (a) New residential, commercial, or industrial development, except as otherwise provided in this division, shall be located within, contiguous with, or in close proximity to, existing developed areas able to accommodate it or, where such areas are not able to accommodate it, in other areas with adequate public services and where it will not have significant adverse effects, either individually or cumulatively, on coastal resources. In addition, land divisions, other than leases for agricultural uses, outside existing 37 developed areas shall be permitted only where 50 percent of the usable parcels in the area have been developed and the created parcels would be no smaller than the average size of surrounding parcels.

Existing marine structures causing water stagnation contributing to pollution problems and fishkills should be phased out or upgraded where feasible. Section 30236, Water supply and flood control Channelizations, dams, or other substantial alterations of rivers and streams shall incorporate the best mitigation measures feasible, and be limited to (l) necessary water supply projects, (2) flood control projects where no other method for protecting existing structures in the flood plain is feasible and where such protection is necessary for public safety or to protect existing development, or (3) developments where the primary function is the improvement of fish and wildlife habitat. Section 30253, Minimization of adverse impacts New development shall do all of the following: (a) Minimize risks to life and property in areas of high geologic, flood, and fire hazard. (b) Assure stability and structural integrity, and neither create nor contribute significantly to erosion, geologic instability, or destruction of the site or surrounding area or in any way require the construction of protective devices that would substantially alter natural landforms along bluffs and cliffs. (c) Be consistent with requirements imposed by an air pollution control district or the State Air Resources Board as to each particular development. (d) Minimize energy consumption and vehicle miles traveled. (e) Where appropriate, protect special communities and neighborhoods that, because of their unique characteristics, are popular visitor destination points for recreational uses.

The reactive approach involves emergency response, attempts to maintain the status-quo, and respond to impacts caused by episodic storm events and other sea level rise impacts. This approach will likely fail to anticipate and prevent or mitigate long-term consequences of sea level rise and may result in significant financial costs, as well as adverse impacts to coastal resources, development, and the city’s economy. Protect Protection strategies employ some sort of engineered structure or other measure to protect or floodproof development (or other coastal resources) in its current location without changes to the development or resources themselves. Protection strategies can be further divided into “hard” and “soft” defensive measures. Examples of a hard approach would be to construct a seawall or revetment, while a soft approach may be to nourish beaches with sand or build sand dunes. Although the California Coastal Act allows for potential protection strategies for existing development, it also directs that new development be sited and designed to avoid hazards and not require future protection that may alter a natural shoreline. Accommodate Accommodation strategies employ methods that modify existing or design new developments or infrastructure in a manner that decreases hazard risks and, therefore, increases the resiliency of the development/infrastructure to the impacts of sea level rise. These accommodation strategies include actions such as elevating structures, retrofitting or using materials to increase the strength of development/infrastructure such as: the ability to handle additional wave impacts; building structures that can easily be moved and relocated; using additional setback distances to account for acceleration of erosion; and clustering development in less vulnerable areas. Retreat Retreat strategies relocate or remove existing development out of hazard areas and limit the construction of new development in vulnerable areas.

Land Use Maps Amend the City of Carlsbad Local Coastal Program – Coastal Land Use Maps to include the North Coast Corridor Public Works Plan/Transportation and Resource Enhancement Program (NCC PWP/TREP) Project Overlay Map and Project Overlay Improvements Map. Amend the City of Carlsbad Habitat Management Plan (HMP) Map/s to include the North Coast Corridor Public Works Plan/Transportation and Resource Enhancement Program (NCC PWP/TREP) HMP Map Changes. 1.1 North Coast Corridor PWP/TREP Overlay Land Use Plan Map The City of Carlsbad Local Coastal Program Land Use Maps and Circulation Element illustrate the Local Coastal Program land use designation for each property. The land use designation denotes the type, density and intensity of development and uses that may be permitted for each property, consistent with applicable Local Coastal Program policies. In addition to the land use designations included in the certified Land Use Maps, an overlay is applied to those land areas within the City of Carlsbad as identified on the NCC PWP/TREP Project Overlay Map (Map 1). The NCC PWP/TREP Project Overlay provides the applicable standard of review for the NCC PWP/TREP, which, if approved, will authorize the development, operation, and maintenance of specific rail, highway, transit, bicycle, pedestrian, community and resource enhancement projects defined therein. The goals of the NCC PWP/TREP are to improve and maintain regional mobility and access to coastal resources in the North Coast Corridor, to implement a program to protect, restore, and enhance sensitive coastal resources along the North Coast Corridor and to mitigate potential resource impacts caused by implementation of the transportation and community enhancement projects. The City of Carlsbad Local Coastal Program NCC Project Overlay Improvements Map (Map 2) identifies those specific rail, highway, transit, bicycle, pedestrian, community and resource enhancement projects envisioned to occur within the jurisdictional boundaries of the City of Carlsbad pursuant to the NCC PWP/TREP. The City of Carlsbad Habitat Management Plan (HMP) Map Changes (Map 3) identify project impacts and the addition of new HMP Hardline Preserve area to offset those impacts, as well as technical map corrections required to remove HMP Hardline Preserve currently located within Caltrans/LOSSAN right of ways that are not subject to the HMP. In areas within the NCC Project Overlay Map where the Local Coastal Program land use designation currently does not allow for transportation and restoration related uses, these uses would now be identified as an allowable use, with the portions of the NCC PWP/TREP that are incorporated into the overlay serving as the standard of review for all proposed development that is outside of the Coastal Commission’s retained jurisdiction and not handled solely through federal consistency review. If the NCC PWP/TREP is approved, subsequent regulatory reviews shall be processed under the framework and guidance provided within the NCC PWP/TREP. 2. North Coast Corridor PWP/TREP Overlay Project Components and Land Use Plan Policies 2.1 Pursuant to Senate Bill (SB) 468, the NCC Project is defined as a 27-mile long series of projects within the coastal zone that includes improvements to a segment of I-5 and the Los Angeles-San Diego-San Luis Obispo (LOSSAN) rail corridor. The NCC PWP/TREP includes 27-miles of regional mobility, community and resource Oct. 12, 2021 Item #7 Page 323 of 428 Appendix A City of Carlsbad A2 Local Coastal Program enhancement projects planned in Northern San Diego County, a portion of which are located within, or partially within, the City of Carlsbad (“City”) coastal zone. The NCC Public Works Plan (“PWP”) is integrated, within a single document, with the NCC Transportation and Resource Enhancement Program (“TREP”), which collectively provide the coastal policy framework under which the City, Coastal Commission, and other affected agencies and interested parties can evaluate overall NCC PWP/TREP benefits and potential impacts to coastal zone resources, phased implementation, mitigation measures, and feasible alternatives in the context of the City’s local coastal program, the California Coastal Act, regional mobility plans and coastal resource enhancement goals. The TREP provides the basis for Coastal Commission federal consistency review and informs conflict resolution to ensure the overall NCC PWP/TREP is consistent with applicable California Coastal Management Program/Coastal Act policies. Chapter 3 policies of the Coastal Act provide the standard of review for the federal consistency review and, pursuant to the TREP, rail projects, will be evaluated on a case-by-case basis to determine whether the Coastal Commission’s review of those projects will be limited to the federal consistency review process only. In addition to providing an overall summary of the NCC projects for purposes of Coastal Act review, the PWP also provides authorization for future development and guidance for future coastal development permitting of other development within the NCC Project Overlay area and informs how the Coastal Commission may resolve any conflicts between Coastal Act policies. The PWP incorporates projects (including highway projects, rail projects other than those subject to the federal consistency review process only, and community and resource enhancement projects) that are both subject to coastal development permit and/or local coastal program requirements and that are located outside the areas of the Commission’s retained jurisdiction. Following Coastal Commission approval of the PWP, project-specific Notice of Impending Developments (NOIDs) provide the mechanism by which the project proponent will bring forward specific projects for Coastal Commission review (except for those projects occurring within areas of the Coastal Commission’s original jurisdiction and rail projects subject to the federal consistency review process only). The approved PWP provides the standard of review for those specific NCC Project NOIDs, as applicable. 2.2 The NCC PWP/TREP includes public works projects that: 1) will meet the public needs of an area greater than that included in the City’s certified local coastal program area, and 2) which were not anticipated when the local coastal program was certified by the California Coastal Commission. The policies, development/design strategies and implementation measures of the NCC PWP/TREP are intended to efficiently plan and implement the corridor projects located in the City of Carlsbad coastal zone as integral elements of the NCC Project, all of which are necessary to implement a balanced, integrated approach to maintain and improve regional mobility as well as enhancement and continued use and enjoyment of coastal resources, while addressing potential unavoidable and minimized project impacts and/or conflicts with the coastal resources planning and management policies of the City’s local coastal program and California Coastal Act. The policies and implementation measures of the NCC PWP/TREP provide the applicable standard of review for implementation of projects to be reviewed and approved pursuant to the PWP. The policies and design/development strategies of the NCC PWP/TREP will serve as guidance for Coastal Commission review of rail projects, evaluated on a case-by-case basis to determine whether the Coastal Commission’s review of those projects will be limited to the federal consistency review process only, and provides guidance for obtaining federal consistency for those identified rail projects, as applicable. The NCC PWP/TREP will also serve as guidance for Coastal Commission review of projects located within the Coastal Commission’s retained Oct. 12, 2021 Item #7 Page 324 of 428 Appendix A City of Carlsbad A3 Local Coastal Program jurisdiction pursuant to § 30519, which will be subject to separate coastal development permits reviewed by the Coastal Commission. 2.3 The NCC PWP/TREP is comprised of various elements including transportation infrastructure improvements as well as community and resource enhancement projects that in their totality would result in significant benefits to the Coastal Zone. The PWP/TREP provides the mechanism to ensure that the various specific project types included within the NCC Project Overlay are implemented in such a manner that maximum benefits to sensitive resources are achieved while impacts are avoided and/or minimized to the greatest extent feasible. The following components are included within the NCC Project Overlay. 2.3.1 Highway Improvements. The NCC PWP/TREP includes Interstate Highway 5 improvements that consist of an 8+4 highway design that provides eight general purpose lanes and four managed lanes along with other associated highway improvements, including but not limited to, interchanges, direct access ramps, auxiliary lanes, signage, and other safety and maintenance elements. These improvements would improve public access through the NCC PWP/TREP area while also enhancing carpool and public transit usage, and result in decreased vehicle hours traveled and energy consumption. 2.3.2 Mass Transit Improvements. The NCC PWP/TREP includes carefully phased improvements to the LOSSAN rail corridor that would result in the double-tracking of the rail corridor, as well as other operational and station improvements. The NCC Project also includes road and intersection improvements that would facilitate the introduction of enhanced bus service along the Coast Highway. These improvements would result in enhanced mass transit opportunities through the corridor and result in improved public access while minimizing energy consumption. 2.3.3 Non-motorized Transportation and Community Enhancements. The NCC PWP/TREP establishes a 27 mile-long North Coast Corridor bikeway, and includes concurrent construction of primary segments of the bikeway within the I-5 right-of-way, that would provide a new connected north-south accessway for bicyclists and pedestrians through the corridor. The NCC PWP/TREP also includes other path and trail linkages and community enhancements designed to provide enhanced connectivity between all travel modes within the NCC PWP/TREP area, including segments of the Coastal Rail Trail located within the LOSSAN right-of-way. These improvements would result in enhanced public access opportunities while at the same time reducing energy consumption and vehicle miles traveled. 2.3.4 Restoration Enhancements. The NCC PWP/TREP includes significant restoration enhancement with specific projects located within coastal lagoon systems throughout the NCC Coastal Zone. Specific projects include: A.Habitat establishment, restoration, enhancement and preservation for upland ESHA and wetland resource impacts B.Optimized bridge projects (lagoon bridge lengthening along the I-5 and LOSSAN rail corridors) designed to improve lagoon system function and values and facilitate large-scale lagoon restoration C.Endowment that is intended to increase the capacity for long-term management of the Los Peñasquitos and Batiquitos Lagoons inlet maintenance projects and/or other significant resources in the corridor, and support stewardship of these resources in perpetuity D.Funding for large-scale lagoon restoration programs for San Elijo Lagoon and/or Buena Vista Lagoon This suite of restoration enhancements would result in important biological and hydrological improvements to sensitive coastal resources. Oct. 12, 2021 Item #7 Page 325 of 428 Appendix A City of Carlsbad A4 Local Coastal Program 2.4 The NCC PWP/TREP includes detailed procedural and implementation requirements related to the phasing of specific project construction. These linkages within the PWP/TREP are intended to ensure that the infrastructure components do not outpace the necessary resource and community enhancement components of the NCC PWP/TREP. The PWP/TREP includes project phasing that links the various specific project types encapsulated within the NCC Project in such a manner to provide maximum benefits for the coastal resources within the NCC PWP/TREP area while at the same time achieving the transportation goals for the NCC corridor. These phasing requirements relate both to the successful completion of resource enhancement projects as well as demonstrated interconnectivity between transportation systems. The PWP/TREP Phasing Plan and Implementation Framework is divided into short, mid, and long term project phases; and, in order for a specific project to be initiated, all of the components of the prior phase must be completed, as defined in the PWP/TREP, before the subject project can be initiated. Project shifts between phases may be allowed if they would not result in impacts to coastal resources that were not accounted for in this LCP and NCC PWP/TREP and would result in equivalent or greater multi-modal and coastal access improvements as compared to the PWP/TREP Phasing Plan and Implementation Framework approved by the Coastal Commission. Amendments to the NCC PWP to authorize such project shifts are therefore permitted if they are in conformance with Section 2.5 of the NCC Overlay. 2.5 The NCC PWP project scope and resource protection policies, design/development strategies, and implementation measures may require amendment by Caltrans, SANDAG and the Coastal Commission to address modified project designs, changes in available project funding and/or phasing needs, to incorporate new, high priority resource enhancement opportunities, and/or to address changed site conditions and resource protection requirements within the NCC Project Overlay area. The NCC PWP, as may be amended from time- to-time, shall continue to provide the standard of review for implementation of projects reviewed and approved pursuant to the PWP/TREP. Amendment of the NCC PWP that would not result in conflicts with the policies contained within the NCC Project Overlay would not require future amendment to the City’s Local Coastal Program. Although the following list is not exhaustive, these changes to the NCC PWP would trigger the need for an amendment to the City’s Local Coastal Program: A.The addition of new projects not consistent with NCC Project Overlay Policy 2.3, or that involve significant impacts to coastal resources not considered in the original PWP or not addressed by PWP policies, development/design strategies and implementation measures. B.Alteration of resource protection policies or mitigation ratio standards within the NCC PWP inconsistent with the policies contained within the NCC Project Overlay C.Project shifts between phases that would result in reduced multi-modal performance and coastal access, or without necessary mitigation or coordination between other transportation modes as compared to the PWP/TREP Phasing Plan and Implementation Framework approved by the Coastal Commission, or project shifts that would result in significant unmitigated impacts to coastal resources not considered in the original PWP or not addressed by PWP policies, development/design strategies and implementation measures.. 2.6 Rail, highway, bicycle, pedestrian, community and resource enhancement projects, as defined within and permitted by the NCC PWP are permitted uses on lands subject to the NCC Project Overlay, and shall be permitted to be constructed, opened, operated and maintained for intended public use or benefit pursuant to the PWP and NOID, as provided in Sections 30605 and 30606 of the Coastal Act. All projects specifically defined Oct. 12, 2021 Item #7 Page 326 of 428 Appendix A City of Carlsbad A5 Local Coastal Program within and permitted by the NCC PWP, upon approval by the Coastal Commission are herein incorporated by reference. 2.7 Specific rail projects not handled solely through federal consistency review and conceptual highway, bike and pedestrian enhancement components of the PWP may be altered through future PWP amendments and then ultimately authorized by subsequent NOIDs, or SANDAG/Caltrans may, in consultation with the City and Coastal Commission, choose to submit a coastal development permit application to the City for these projects, in which case the standard of review will be the City’s certified Local Coastal Program. 3. North Coast Corridor PWP/TREP Coastal Resource Protection Policies If the Commission approves the NCC PWP all projects and programs as defined within and undertaken pursuant to that document within the City of Carlsbad shall conform to the following resource protection policies: 3.1 Coastal Access and Recreation 3.1.1 Maximum public access to coastal and inland recreational resources in the North Coast Corridor shall be protected, and where feasible, enhanced, consistent with public safety needs and sensitive coastal resource protection policies of the NCC PWP/TREP (prepared by Caltrans/SANDAG and dated August 13, 2014). Any future amendment of the original PWP shall not decrease the level of public access improvements guaranteed by the policies in the NCC PWP/TREP such that the project as a whole would no longer be, on balance, most protective of significant coastal resources. 3.2 Energy Conservation and Emissions Reduction 3.2.1 New transportation and associated community and resource enhancement projects in the North Coast Corridor shall seek to minimize increases in energy consumption, vehicle hours traveled and person hours of travel, and be consistent with San Diego County Air Pollution Control District and California Air Resources Board requirements. Where North Coast Corridor development may potentially increase energy consumption or be inconsistent with air pollution requirements, feasible mitigation measures shall be required and implemented consistent with the policies of the NCC PWP/TREP (prepared by Caltrans/SANDAG and dated August 13, 2014). Any future amendment of the original PWP shall not decrease the energy conservation and emissions reduction improvements guaranteed by the policies in the NCC Corridor PWP/TREP such that the project as a whole would no longer be, on balance, most protective of significant coastal resources. 3.3 Transit and Smart Growth 3.3.1 Measures to improve public access to beaches and recreation areas through the use of transit and alternative means of transportation in the North Coast Corridor shall be developed in coordination with the Coastal Commission, City, Caltrans, SANDAG and any other appropriate transit providers, and may include, where determined feasible and consistent with the policies of the NCC PWP/TREP (prepared by Caltrans/SANDAG dated August 13, 2014): A.Provision of parking facilities for bicycles, motorcycles and transit vehicles at recreation areas and transit stations; B.Development of park-and-ride or other staging facilities at points along Interstate Highway Route 5; C.Construction of road and intersection improvements to Interstate Highway Route 5 and arterial streets Oct. 12, 2021 Item #7 Page 327 of 428 Appendix A City of Carlsbad A6 Local Coastal Program to facilitate bus travel; D.Installing or improving bicycle and pedestrian overpasses and/or undercrossings along State Highway Route 5 and the LOSSAN rail corridor where determined feasible; and, E.Providing bicycle and pedestrian facilities and routes that connect with public transit centers, thereby promoting access to and use of carpooling and other public transit opportunities. Any future amendment of the original PWP shall not decrease improvements that support and facilitate mass transit, other alternative means of transportation and smart growth guaranteed by the policies in the NCC PWP/TREP such that the project as a whole would no longer be, on balance, most protective of significant coastal resources. 3.4 Marine Resources: Water Quality and Wetlands 3.4.1 North Coast Corridor transportation and community enhancement projects shall be sited and designed such that marine resources are maintained, enhanced, and, where feasible, restored. North Coast Corridor water quality shall be restored by minimizing wastewater discharges, controlling runoff, preventing depletion of groundwater supplies and substantial interference with surface water flow, encouraging wastewater reclamation, maintaining natural vegetation buffer areas, and minimizing alteration of natural watercourses, where feasible. North Coast Corridor transportation and community enhancement projects shall be planned and designed to protect and, where feasible, enhance water quality of the North Coast Corridor’s lagoons, streams, and smaller watershed drainages which support open water, wetland, and riparian habitats, consistent with the policies of the NCC PWP/TREP (prepared by Caltrans/SANDAG dated August 13, 2014). Where otherwise approvable new development may potentially result in negative impacts to open coastal waters, wetlands, and estuaries, appropriate mitigation measures shall be required and implemented. North Coast Corridor project development in and adjacent to open water, wetland and riparian habitats shall be limited to the uses specified in Sections 30233 and 30236 of the Coastal Act, as applicable, and/or uses specifically defined within and permitted by the NCC Project Overlay. Any future amendment of the original PWP shall not decrease the level of water quality improvements or protection of wetlands guaranteed by the policies in the NCC PWP/TREP such that the project as a whole would no longer be, on balance, most protective of significant coastal resources. 3.5 Environmentally Sensitive Habitat Areas (ESHA) 3.5.1 North Coast Corridor transportation and community enhancement projects shall be sited and designed to ensure that ESHAs are protected against any significant disruption of habitat values, and development in areas adjacent to ESHAs shall be sited and designed to prevent impacts that would significantly degrade those areas, and be compatible with the continuance of those habitat and recreation areas, consistent with the policies of the NCC PWP/TREP (prepared by Caltrans/SANDAG dated August 13, 2014). Where otherwise approvable new development may potentially result in negative impacts to ESHAs and other sensitive coastal habitats, appropriate mitigation measures shall be required and implemented. North Coast Corridor project development in and adjacent to ESHAs shall be limited to the uses specified in Section 30240 of the Coastal Act and/or uses specifically defined within and permitted by the NCC Project Overlay. Any future amendment of the original PWP shall not decrease the level of protection of ESHA guaranteed by the policies in the NCC PWP/TREP such that the project as a whole would no longer be, on balance, most protective of significant coastal resources. Oct. 12, 2021 Item #7 Page 328 of 428 Appendix A City of Carlsbad A7 Local Coastal Program 3.6 Agricultural Resources 3.6.1 North Coast Corridor transportation, community and resource enhancement projects shall minimize impacts to agricultural resources consistent with the policies of the NCC PWP/TREP (as prepared by Caltrans/SANDAG dated August 13, 2014). Where otherwise approvable new development may potentially convert agricultural uses to non-agricultural uses, appropriate mitigation measures shall be required and implemented. North Coast Corridor project development in areas containing significant agricultural resources shall be limited to the uses and circumstances specified in Sections 30241, 30241.5 and 30242 of the Coastal Act and/or uses specifically defined within and permitted by the NCC Project Overlay. Any future amendment of the original PWP shall not decrease the level of protection of agricultural resources guaranteed by the policies in the NCC PWP/TREP that the project as a whole would no longer be, on balance, most protective of significant coastal resources. 3.7 Archaeological and Paleontological Resources 3.7.1 Transportation, community and resource enhancement projects in the North Coast Corridor shall strive to protect and minimize impacts to archaeological and paleontological resources. Where North Coast Corridor projects may potentially adversely impact archaeological or paleontological resources, appropriate mitigation measures shall be required and implemented consistent with the policies of the NCC PWP/TREP (as prepared by Caltrans/SANDAG and dated). Any future amendment of the original PWP shall not decrease the level of protection of archaeological and paleontological resources guaranteed by the policies in the NCC PWP/TREP such that the project as a whole would no longer be, on balance, most protective of significant coastal resources. 3.8 Coastal Visual Resources 3.8.1 North Coast Corridor project development shall be sited and designed in a manner that avoids and minimizes negative impacts to visual resources and protects, to the extent feasible, scenic public views to significant coastal resources, including views of the ocean and coastline, coastal lagoons and river valleys, and significant open space areas. North Coast Corridor project development shall be sited and designed to be compatible with existing development and surrounding areas such that potential impacts of grading, operational activities, community enhancement improvements and direct lighting on public views outside of the transportation facilities are limited to the greatest extent feasible. North Coast Corridor project development shall be planned to be consistent with the visual resource protection policies of the NCC PWP/TREP (as prepared by Caltrans/SANDAG and dated August 13, 2014). Any future amendment of the original PWP shall not decrease the level of protection of coastal visual resources guaranteed by the policies in the NCC PWP/TREP such that the project as a whole would no longer be, on balance, most protective of significant coastal resources. 3.8.2 In scenic public view areas in the North Coast Corridor, roadway improvements, including culverts, retaining walls, bridges or overpasses shall be designed and constructed to protect public views and avoid or minimize visual impacts and to blend in with the natural setting as viewed from adjoining public view points, to the extent feasible. 3.9 Conflict Resolution 3.9.1 The NCC Project Overlay authorizes development that, in isolation, is recognized to be inconsistent with the Oct. 12, 2021 Item #7 Page 329 of 428 Appendix A City of Carlsbad A8 Local Coastal Program Chapter 3 policies of the Coastal Act. However, denial of the project would result in Coastal Zone effects that are inconsistent with other Chapter 3 policies. The project as a whole resolves these conflicts in a manner that is most protective of significant coastal resources. Due to the fact that the NCC PWP/TREP raises conflicts between Coastal Act policies, and the recognition of the Coastal Act’s conflict resolution process as it pertains to this project in Streets and Highways Code section 103(f)(2), conflict resolution, including under Coastal Act section 30007.5, may be used to resolve conflicts between coastal resources protection policies with respect to the PWP/TREP. The conflict resolution provisions relied upon by the Coastal Commission in reviewing the NCC PWP/TREP provide support and rationale as to why the coastal resource protection policies of the NCC Project Overlay could be considered consistent with the Coastal Act, on balance, despite inconsistencies with individual Chapter 3 policies. 3.10 Precedential Effect of Overlay Where there are conflicts between the policies set forth in the NCC PWP/TREP, as may be amended by Caltrans, SANDAG and the Coastal Commission from time-to-time, and those set forth in any other element of the City’s certified Local Coastal Program, General Plan, zoning or any other ordinance, the policies of the NCC Project Overlay and the policies, design/development strategies, and implementation measures of the NCC PWP/TREP shall take precedence for any project and/or use included in the NCC PWP/TREP as approved by the Coastal Commission for the North Coast Corridor except in cases where an amendment to the NCC Project Overlay would be required as previously described above in NCC Overlay Policy 2.5 .

INTRODUCTION There is broad agreement in the scientific community that the earth is predicted to warm and that sea levels will rise as a result of the thermal expansion of water and increased contributions from melting glaciers (Coastal and Ocean Working Group of the California Climate Action Team (CO-CAT) 2013; California Coastal Commission 2015). Though there is consensus among the scientific community on these concepts, the timing and severity of sea level rise is relatively uncertain and is dependent on region- specific conditions. The uncertainty in the sea level rise projections is a result of future global emissions of carbon dioxide (a function of future social behavior) and the non-linear response of the ocean to warmer temperatures and contributions from land-based ice sources. Thus, planning for sea level rise must consider high and low estimates of sea level rise. Planning for a range of potential future conditions provides the City of Carlsbad with the tools to make current and future planning decisions that allow the city’s resources to adapt to changing conditions. This vulnerability assessment presents a Carlsbad-specific sea level rise analysis to support an update to the city’s Local Coastal Program and Zoning Ordinance. The assessment evaluates the degree to which important community assets are susceptible to, and unable to, accommodate adverse effects of projected sea level rise. The assessment identifies the assets that are likely to be impacted and the causes and components of each asset’s vulnerability. This document is considered “living” as it is to be updated as the best available science changes and modeling improves. The study area was divided into four shoreline and three lagoon planning areas, which were incorporated into three larger planning zones for the purposes of discussion. These planning zones are shown in Figure 1 and are described as follows: ❖ Planning Zone 1 – Includes one shoreline and one lagoon planning area in the northern portion of Carlsbad, as follows: ➢ The Village Shoreline – Approximately 1.4 miles of shoreline from the northern city boundary to Tamarack Avenue. From north to south, the sandy shoreline is backed by a low-lying residential area that transitions to a higher-relief, beach-front roadway (Carlsbad Boulevard). Approximately 80% of this portion of shoreline is armored with various coastal structures (i.e., rip rap, revetments and seawalls). ➢ Buena Vista Lagoon – Includes the southern shore of the lagoon within Carlsbad city limits (approximately 5.3 miles of shoreline). Land uses adjacent to this portion of the lagoon include residential, commercial and open space. None of this lagoon’s shoreline within the City of Carlsbad is armored. The lagoon is primarily a freshwater system due to a weir system that controls tidal flushing at its outlet. The San Diego Association of Governments (SANDAG) is currently considering the restoration of this lagoon. Alternatives being considered include removal of this weir system to allow for increased tidal flow into the lagoon. This assessment evaluates sea level rise for the years 2050 and 2100, as described below in Section 3; for year 2050 this assessment assumed the weir system remains in place as it exists and is still functioning as designed. The removal of the weir system in the near term would not significantly change the lagoon’s vulnerability to sea level rise. By year 2100 this assessment concludes that the sea level will overwash the weir, if still in place in year 2100. This vulnerability assessment will be periodically updated, and if the weir is removed in the future, the lagoon’s vulnerability to sea level rise can be reevaluated. Oct. 12, 2021 Item #7 Page 341 of 428 Sea Level Rise Vulnerability Assessment December 2017 2 ❖ Planning Zone 2 – Includes two shoreline and one lagoon planning area in the central portion of Carlsbad, as follows: ➢ Tamarack/ Warm Waters Shoreline - Approximately 1 mile of shoreline from Tamarack Avenue to the northern boundary of the Terramar neighborhood. This shoreline area consists of sandy beach backed by a coastal roadway (Carlsbad Boulevard) and pedestrian promenade. Approximately 71% of this shoreline is armored, with gunite, vertical seawalls, jetties, revetments and rip rap. Two jetty systems (four total structures) exist along this shoreline to control the mouth of the Agua Hedionda Lagoon and water-cooled effluent from the Encina Power Station. The power station’s water effluent control structures are referred to as the “warm water jetties” and include a short groin on the downdrift side of these features to control erosion. In the near future, the Encina Power Station (a water-cooled facility) will be replaced by an air-cooled, gas-fired, peaker plant that will not require seawater for cooling. The Carlsbad Seawater Desalination Plant will use the Encina Power Station water intake/discharge system once Encina Power Station begins this conversion. ➢ Terramar/Palomar Shoreline – Approximately 1.4 miles of shoreline from the northern boundary of the Terramar neighborhood to Las Encinas Creek. The area consists of a bluff-top residential community (Terramar) to the north and transitions to a beach-front roadway (Carlsbad Boulevard) to the south. Bluffs along this portion of shoreline are mostly moderate to high-relief bluffs with the exception of its lowest point at the mouth of Las Encinas Creek. Approximately 15% of this portion of shoreline, primarily the bluffs in the northern portion (in the vicinity of Terramar) is armored with gunite, seawalls and revetments protecting Carlsbad Boulevard and residential homes at Terramar. ➢ Agua Hedionda Lagoon – Includes approximately 6.3 miles of lagoon shoreline, as well as lagoon waters and adjacent lands, which includes the 186-acre Agua Hedionda Lagoon Ecological Reserve, owned by the State of California and managed by the California Department of Fish & Wildlife. The lagoon is used for commercial and recreational purposes. Land uses adjacent to the lagoon include residential, open space, agriculture, commercial, as well as the power station and desalination plant. Approximately 37% of the lagoon shoreline is armored, primarily with rock revetments to stabilize inlet channels. ❖ Planning Zone 3 - Includes one shoreline and one lagoon planning area in the southern portion of Carlsbad, as follows: ➢ Southern Shoreline – Approximately 2.4 miles of shoreline from Las Encinas Creek to the southern city boundary at South Carlsbad State Beach. The shoreline generally consists of narrow sandy beaches backed by moderate to high relief bluffs. The bluff tops are developed with camping facilities owned and operated by the State of California Department of Parks and Recreation. This portion of shoreline also includes the mouth of the Batiquitos Lagoon, which is controlled by a jetty system. Approximately 9% of this portion of shoreline is armored, primarily with rock revetment at Las Encinas Creek and scattered rip rap within the State Parks. ➢ Batiquitos Lagoon - Includes approximately 7.4 miles of lagoon shoreline, as well as the lagoon waters and all adjacent lands. The lagoon was previously restored and is a nature preserve. Lands surrounding the lagoon have high-relief and are developed with residential, commercial and open space uses. Approximately 11% of the lagoon shoreline is armored, primarily with rock revetments in the vicinity of inlets and bridges.

SCOPE OF WORK As part of a contract with the City of Carlsbad to conduct analysis of sea level rise and to update the city’s Local Coastal Program and Zoning Ordinance, Moffatt & Nichol and Revell Coastal, as sub-consultants to Michael Baker International, are conducting the following services for the city: 1. Analysis and mapping of sea level rise hazards – Utilize Coastal Storm Modeling System (CoSMoS) 3.0 results to map sea level rise hazards for two future planning horizons (2050 and 2100). 2. Risk assessment – Determine and prioritize the relative risks to assets within each of the planning areas based on potential consequences and likelihood of impacts. Develop adaptation strategies to minimize risks from hazards and to protect coastal resources. 3. Stakeholder and agency coordination – Attend community stakeholder and technical workshops, public hearings, and coastal commission meetings to support the Local Coastal Program and Zoning Ordinance updates. This vulnerability assessment will inform the development of sea level rise adaptation strategies, as well as the update to the city’s Local Coastal Program and Zoning Ordinance. Oct. 12, 2021 Item #7 Page 344 of 428 Sea Level Rise Vulnerability Assessment December 2017 5 3. COASTAL HAZARD MAPPING This section summarizes how coastal hazards were mapped in this vulnerability assessment. See Attachment A for more detailed information on data inputs, assumptions and limitations. Carlsbad’s exposure to future rates of sea level rise was determined using preliminary results from the CoSMoS 3.0 model. CoSMoS is a multi-agency effort led by the U.S. Geological Survey (USGS) to make detailed predictions (meter scale) of coastal flooding and erosion based on existing and future climate scenarios for southern California. The modeling effort depicts coastal flooding, shoreline change and bluff response to a composite, 100-year wave event in combination with various rates of sea level rise and baseline water levels (i.e., high tide, storm surge, sea level anomaly and river discharge). The results from four CoSMoS sea level rise scenarios (i.e., 0.5 meters [m], 1.0 m, 1.5 m and 2.0 m) were made available in the preliminary (Phase I) CoSMoS data release in November 2015. The CoSMoS 0.5-m and 2.0-m sea level rise scenarios roughly align with the projected high sea level rise from the 2012 National Research Council’s report for the 2050 and 2100 planning horizons. Therefore, these sea level rise scenario results were used as the basis for this vulnerability analysis. A comparison of the National Research Council’s 2012 sea level rise projections for the planning horizons compared to the CoSMoS scenarios used is shown in Table 1. Table 1: Comparison of Sea Level Rise Scenarios Year 2012 National Research Council Sea Level Rise Projections CoSMoS 3.0 Sea Level Rise Scenario Difference (CoSMoS vs. 2012 National Research Council – High SLR) (ft) Projection (ft) Uncertainty (ft, +/-) Low Range (ft) High Range (ft) 2050 0.9 0.3 0.4 2.0 0.5 m (1.6 ft) 0.4 2100 3.1 0.8 1.5 5.5 2.0 m (6.6 ft) 1.1 CoSMoS provides projections of shoreline erosion, coastal flooding and bluff erosion in the city. These results were used to represent inundation, coastal flood and bluff hazard zones. In addition to these hazards, a fluvial flood hazard zone was developed by Moffatt & Nichol to more accurately depict areas subject to future river floods. The hazard zones used in this analysis are described as follows: ❖ Inundation Hazard Zone – Sea level rise will result in the migration of existing coastal and lagoon shorelines in the landward direction. The inundation hazard zone is an area that will be subject to daily wetting and drying associated with tides. For beaches, CoSMoS future mean sea level (located at a beach elevation of 2.9 feet, MLLW) shoreline positions were used as a proxy for the future inundation hazard zone. For the lagoons, an elevation of mean higher high water (5.3 feet, MLLW) was used as a proxy for the future inundation hazard zone. The inundation hazard zone, shown on the coastal hazard maps in this assessment, represents the future shoreline position or the beach position at future high tide. The inundation hazard zone does not reflect potential wave run up with storm impacts, which could add to water level and increase flooding. The flood hazard zone, described below, reflects areas vulnerable to flooding. ❖ Bluff Hazard Zone – Rising sea levels may result in the increased erosion of coastal bluffs due to more frequent exposure to wave attack. Coastal bluff erosion may be gradual or may be episodic with a more significant loss related to a storm event. CoSMoS bluff erosion projections were used to represent the bluff hazard zone for the two planning horizons. Oct. 12, 2021 Item #7 Page 345 of 428 Sea Level Rise Vulnerability Assessment December 2017 6 ❖ Flood Hazard Zone – Includes coastal and lagoon zones, described as follows: ➢ Coastal – coastal flooding events are typically short in duration (i.e., hours) and occur episodically in association with extreme wave events (e.g., 100-year return period event). These events, in combination with high tides represent the coastal flood hazard zone. CoSMoS flooding limits were used to represent the coastal flood hazard zone for the two planning horizons. ➢ Fluvial (lagoon) – sea level rise has the potential to result in higher water levels in the city’s lagoons during significant precipitation events (i.e., 100-year return period river flood). Moffatt & Nichol found that CoSMoS underestimates the potential fluvial flood limits within the city. A revised fluvial flood hazard zone was generated based on the results of existing numerical models of the lagoons within the city. Oct. 12, 2021 Item #7 Page 346 of 428 Sea Level Rise Vulnerability Assessment December 2017 7 4. VULNERABILITY AND RISK ASSESSMENT METHODS Methodology for assessing vulnerability and risk were based on the following guidelines developed to assist with adaptation planning efforts aimed at preparing for the effects of climate change and sea level rise: ❖ California Coastal Commission Sea Level Rise Policy Guidance adopted by the California Coastal Commission, August 12, 2015. ❖ Preparing for Climate Change: A Guidebook for Local, Regional, and State Governments, published by ICLEI-Local Governments for Sustainability (Snover, A.K. et al. 2007). ❖ California Adaptation Planning Guide, Planning for Adaptive Communities prepared by CalEMA, now known as CalOES, and the California Natural Resources Agency (CalEMA 2012). A vulnerability assessment was performed to identify impacts that sea level rise and coastal hazards, as described in Section 3, may have on existing resources and assets within the city. Vulnerability was assessed as a function of an asset’s exposure, sensitivity, and adaptive capacity. A numerical rating system was used to develop an overall vulnerability score for each asset category at the 2050 and 2100 time horizons. The definition of these terms and the rating system used are described in Table 2. A vulnerability rating of low (score of 3-4), moderate (score of 5-7), or high (score of 8-9) was assigned for each asset category based on the sum of ratings for exposure, sensitivity and adaptive capacity. While the vulnerability assessment was performed to identify impacts from sea level rise, a risk assessment was performed to evaluate the magnitude of these impacts and likelihood of occurrence. The risk assessment was performed qualitatively to help the city manage risk related to sea level rise in their planning and decision-making process. Assessment of risk can be subjective and is not intended to establish priorities for future planning. Oct. 12, 2021 Item #7 Page 347 of 428 Sea Level Rise Vulnerability Assessment December 2017 8 Table 2: Vulnerability Rating System Exposure is the degree to which an asset or resource is susceptible to coastal hazards such as flooding, inundation and bluff erosion for a given sea level rise scenario. The mapped hazard zones, shown in Section 5 and Attachment B were used to rate the level of exposure to a given asset or category. Category Rating Explanation Exposure Low (1) Asset or resource partially exposed to flooding, inundation or bluff erosion. Moderate (2) Asset or resource moderately exposed to flooding, inundation or bluff erosion. High (3) The majority of the asset or resource is exposed to flooding, inundation or bluff erosion. Sensitivity is the degree to which the function of an asset or resource would be impaired (i.e., weakened, compromised or damaged) by the impacts of sea level rise. Example: Carlsbad Boulevard in the vicinity of Tamarack Beach has a high sensitivity to sea level rise because even minor flooding can cause significant disruption in service. Category Rating Explanation Sensitivity Low (1) Asset or resource is not affected or minimally affected by coastal hazards at a given sea level rise scenario. Moderate (2) A moderately sensitive asset or resource may experience minor damage or temporary service interruption due to coastal hazard impacts, but can recover relatively easily. High (3) A highly sensitive asset or resource would experience major damage or long-term service interruptions due to coastal hazard impacts, requiring significant effort to restore/rebuild to original condition. Adaptive capacity is the inherent ability of an asset or resource to adjust to sea level rise impacts without the need for significant intervention or modification. Example: Some wetland habitat has a high adaptive capacity due to their ability to naturally migrate landward and upward with rising water levels provided adequate space exists. Category Rating Explanation Adaptive Capacity High (1) Asset or resource can easily be adapted or has the ability and conditions to adapt naturally. Moderate (2) Asset or resource can be adapted with minor additional effort. Low (3) Asset or resource has limited ability to adapt without significant changes. The following vulnerability assessment evaluates exposure, sensitivity, and adaptive capacity for different asset categories in each of the three planning zones. The assessment includes evaluation of shoreline area vulnerabilities, as well as lagoon vulnerabilities. Sea level rise impacts within the shoreline planning areas are discussed in terms of inundation (area of future daily tidal influence as a result of beach erosion), flooding (as a result of wave run-up associated with extreme waves), and bluff erosion. Additionally, inland waters at the Buena Vista, Agua Hedionda, and Batiquitos Lagoons were evaluated for inundation (shoreline position change as a result of daily tidal inundation) and fluvial flooding (from extreme precipitation events) as a result of sea level rise. In order to assess the vulnerability in each planning zone, assets were sorted into defined categories. These asset categories and general vulnerability assumptions are described below: ❖ Beaches – The exposure of sandy beaches to sea level rise impacts is high with anticipated erosional impacts with any sea level rise scenario. In a natural setting, beaches can be thought to have a high adaptive capacity because they will naturally adjust to a rising sea level if adequate sand exists in the system. However, the adaptive capacity of beaches can be low in areas where beaches are backed by coastal structures or development or where insufficient sand exists in the system. Continuation of sand bypassing projects, such as the Oceanside Harbor and Agua Hedionda projects, are important in restoring littoral transport of sand to beaches downdrift of these sediment blocking features. Continuation of episodic beach nourishment projects will also be important to offset regional sediment deficits. Oct. 12, 2021 Item #7 Page 348 of 428 Sea Level Rise Vulnerability Assessment December 2017 9 ❖ Public Access Ways – Public access ways consist of vertical access ways to and lateral access ways along the beach and lagoons. A city GIS data layer was used to identify these vertical and lateral public access ways. ❖ State Parks – Numerous state park facilities exist along the city’s shoreline and consist of public day- use parking lots and campgrounds. State park facilities are recognized as important assets to the city in terms of economic and recreation value. The state park facilities also provide an important low cost visitor-serving amenity with prime access to coastal resources. Though economic impacts to the physical structures (i.e., asphalt paving, restrooms and some utilities) within the affected state parks would be relatively low, loss of these amenities would be significant since space for these features to move inland is not available. ❖ Parcels - Parcels evaluated for sea level rise impacts include privately held lots of various land uses or zoning. Current city zoning data was used to categorize the parcels into their respective zones. Parcels generally have a low adaptive capacity and high sensitivity though these ratings can be affected by the life expectancy of the development, the permit history and the physical condition of any shoreline protective device that may exist. Additionally, the adaptive capacity of buildings could potentially be moderate for some parcels with finished floors on an elevated building pad. Note that impacts to parcels may not necessarily represent impacts to the physical buildings on that parcel. ❖ Critical Infrastructure (i.e., water/sewer/electrical utilities) – Critical infrastructure includes facilities necessary to run the city effectively and efficiently since loss of water, sewer or power would significantly disrupt quality of life for residents. This infrastructure typically has a high sensitivity and low adaptive capacity. ❖ Transportation Infrastructure (roadways, bike/pedestrian paths, trails) – Roadways are generally highly sensitive to flooding hazards as even minor amounts of flooding on roads can cause significant traffic delays and potentially disrupt emergency service vehicles and evacuation routes. Maintenance and repair requirements may also increase after significant flooding and erosion events (similar to the bluff erosion repair work occurring along Carlsbad Boulevard at Las Encinas Creek). Roadways typically have a low adaptive capacity in that significant costs are associated with relocation or raising of these structures. ❖ Environmentally Sensitive Lands – Environmentally sensitive lands include wetlands, riparian areas, coastal prairies, woodlands and forests, and other natural resources in the coastal zone. These lands can have a high adaptive capacity in areas where adequate space exists for them to naturally shift landward to a rising sea level. Steep topography and existing development in the coastal zone present challenges for the landward migration of many of these lands in the City of Carlsbad. Thus, these areas are generally described as having a low adaptive capacity in the city. A particular asset’s exposure to sea level rise was characterized in terms of hazard type and quantity of assets impacted for each planning horizon. Some resources impacted by sea level rise are difficult to quantify; thus, a qualitative analysis is provided below to generally describe how these assets may be affected by sea level rise. These resources include visual resources, cultural resources, saltwater intrusion into groundwater resources and lifeguard services. These resources are described below: Oct. 12, 2021 Item #7 Page 349 of 428 Sea Level Rise Vulnerability Assessment December 2017 10 ❖ Visual Resources – Visual resources in the city include views of the beaches, bluffs, and the Pacific Ocean. Sea level rise is not anticipated to affect the existing viewing opportunities of the bluffs and ocean in the city, however, beaches may be impacted as a result of accelerated erosion if no management actions are taken to mitigate these impacts (e.g., beach nourishment). Without such actions, beaches would become narrower and beach views would be impacted. Views of the ocean may also be impacted if coastal structures are built to protect assets from sea level rise or if structures are raised in height to accommodate sea level rise. Design standards in designated scenic areas can be implemented to protect visual resources while minimizing hazards. ❖ Cultural (historical, archaeological and paleontological) Resources – Exposure of historical sites to coastal hazards can lead to irreplaceable loss of cultural heritage. Identified historical sites in the City of Carlsbad were determined to not be at risk to sea level rise hazards through year 2100. Archaeological and paleontological resources in the city may be vulnerable to sea level rise hazards. Maps of these resources are not made publicly available for their protection. New development requires a site-specific evaluation of potential sea level rise impacts to these resources. Monitoring programs and plans may be imposed on new development where artifacts may be vulnerable to sea level rise. Additionally, consultation with Native American tribes and State Historic Preservation Officer (SHPO) would be required if cultural resources are found to be at risk to sea level rise on a new development site. ❖ Saltwater Intrusion – As sea levels rise, saltwater migrates inland through the soil and underground pathways into groundwater resources. Research suggests that sea level rise is likely to degrade fresh groundwater resources in certain areas. The degree of impact will vary due to local hydrogeological conditions. Unconfined aquifers are generally found to be the most vulnerable to saltwater intrusion from sea level rise. Groundwater use is limited and not widespread for potable or irrigation purposes in the City of Carlsbad. Thus, potential saltwater intrusion impacts because of sea level rise is not considered significant. ❖ Lifeguard Services – Lifeguard services in the city are predominately managed by State Parks, and most lifeguard facilities in the city are temporary and seasonal. Some lifeguard facilities are fixed in permanent locations and others are mobile. Those that are temporary and mobile are moved to different locations on the beach seasonally. Lifeguard facilities may be impacted by sea level rise as a result of accelerated beach erosion if no management actions are taken to mitigate these impacts (e.g., beach nourishment). Without such actions, beaches would become narrower and lifeguard facilities, especially those in locations with bluff backed beaches without area to retreat, may need to be relocated.

VULNERABILITY AND RISK ASSESSMENT Results of the vulnerability assessment are discussed by planning zone in this section. Shoreline protective devices were considered in different ways for the various hazard zones in the CoSMoS model. A summary of how these structures were considered in the modeling is provided below. A more detailed description of these assumptions and limitations is provided in Attachment A. ❖ Inundation Hazard Zone (Coastal) – This zone represents the results from the CoSMoS shoreline erosion model. This model included coastal structures (rip rap, revetments and seawalls) and coastal infrastructure as a non-erodible layer. Thus, shoreline erosion stops once the beach erodes to the point where it encounters the coastal structure or infrastructure. This assumes the structure serves to protect upland assets from frequent wave attack, which may not be the case in all areas. Thus, inundation hazards may be understated in some areas where this non-erodible layer was set. A more detailed analysis of structures approached by this hazard zone may be warranted in some areas. ❖ Inundation Hazard Zone (Lagoon) – Shoreline protection structures are not included in the modeling of this hazard zone. However, since this lagoon area is a tidal system (no wave driven flooding and erosion), these results are not anticipated to be greatly affected by the lack of these structures. ❖ Bluff Hazard Zone – The CoSMoS model did not include bluff shoreline protection structures in the city. Examples of bluff protection structures that were excluded include coastal structures (seawalls, revetments, riprap) and bluff stabilization treatments that exist in the community of Terramar. The CoSMoS model states that coastal structures were not included if the armoring was low enough to be easily overwashed. Determination as to whether armoring was easily overwashed was subjective and was determined by the USGS. Not accounting for these bluff protection structures in the city likely overestimates bluff erosion hazards in areas. ❖ Flood Hazard Zone (Coastal) – Coastal structures were implicitly captured in the CoSMoS model when structures were large enough (e.g., revetments in the Village Planning Area) to be captured in the topographic data set used for the regional study. Small scale features, such as vertical seawalls along Carlsbad Boulevard in the Tamarack Planning Area, were not captured in the model due to the resolution of the topographic data used. Coastal flooding limits are likely overstated in areas where these small scale coastal structures were not captured. A more detailed analysis of this structure would be needed to more accurately define the flood hazard zone in these areas. ❖ Flood Hazard Zone (Lagoon) – Shoreline protection structures are not included in the modeling of this hazard zone. However, since this a tidal system (no wave driven flooding and erosion), these results are not anticipated to be greatly affected by the lack of these structures. Year 2050 and 2100 results are presented and discussed in this section. For simplicity, vulnerability graphics are provided in this section for year 2050 only; vulnerability graphics for year 2100 are included in Attachment B. 5.1. PLANNING ZONE 1 Planning Zone 1 includes the Village Shoreline and Buena Vista Lagoon planning areas. Assets within this zone are vulnerable to inundation, flooding and bluff erosion in the 2050 and 2100 planning horizons. A summary of the vulnerability assessment rating is provided in Table 3. A discussion of the vulnerability and risk assessment is also provided for each asset category.

Beaches Approximately 6 acres of beach area is projected to be impacted by inundation/erosion by year 2050. Beaches are exposed to any rise in sea levels (high exposure) but will continue to provide recreation and storm protection benefits during this time horizon (low sensitivity). Beaches are formed by natural processes and have the ability to adapt to rising sea levels, assuming sufficient sand supplies exist and there is adequate space for the beach to migrate landward. However, the adaptive capacity of beaches is low in areas where beaches are backed by coastal structures or development or where insufficient sand exists in the system. This is the case in this planning area. Development backed beaches are common in southern California and in much of the City of Carlsbad. Thus, the overall vulnerability rating for beaches is moderate for year 2050. This vulnerability poses a moderate risk to the city because there is a high likelihood of beach loss occurring due to sea level rise. Oct. 12, 2021 Item #7 Page 352 of 428 Sea Level Rise Vulnerability Assessment December 2017 13 Vulnerability is rated high for beaches in the 2100 horizon due to the significant erosion expected as the beaches are squeezed between rising sea levels and coastal development. This vulnerability poses a high risk to the city as increased beach erosion will reduce the natural barrier to storm waves and reduce opportunity for beach access and recreation. There are also economic costs associated with such impacts; beach visitation from both in-town and out-of-town guests results in economic benefits to city businesses (e.g., retail, restaurants, hotel). 5.1.2. Public Access Ways Coastal flooding and erosion has the potential to impact vertical (access to) and lateral (access along) beach access ways in the city. For example, erosion of the beach may create a large scarp (or drop off) at the end of a beach access stairway. Wave forces during large surf may also physically damage stairways making them impassable temporarily. A total of 15 vertical beach access ways exist within Planning Zone 1. Most of these beach access ways (i.e., 13) were determined to be potentially impacted by coastal flooding by year 2050. All 15 were found to be vulnerable to flooding and erosion by year 2100. Lateral beach access ways in this planning area include existing trails in the vicinity of Hosp Grove Park and along Carlsbad Boulevard. Approximately 1 mile of existing trails were found to be vulnerable by year 2050. Approximately 2 miles of existing trails were vulnerable by year 2100. The vulnerability of trails in both planning horizons was found to be moderate, owing mostly to the relatively high adaptive capacity of these assets. Beach access ways can generally accommodate flooding and can typically be repaired relatively easily. Similarly, lagoon trails can accommodate some level of flooding and can be relocated when maintenance costs become too high. 5.1.3. Parcels Portions of parcels, where buildings are located, along the northern portion of the Village Planning Area and Buena Vista Lagoon may be exposed to flooding during an extreme event in year 2050. However, the majority of buildings themselves do not appear flooded in this scenario and are fronted by shore protection in the form of a revetment or seawall (low exposure). Parcels were assigned a vulnerability rating of moderate since development is typically sensitive to episodic flooding with little adaptive capacity. This vulnerability poses a moderate risk to parcel owners due to the high consequence of flooding impacts on parcel usage and value. The likelihood of occurrence of this type of impact is relatively low and would only be expected during extreme storm events. Vulnerability of parcels is rated high for the 2100 scenario due to the increased exposure and sensitivity of parcels to flooding, inundation and bluff erosion during an extreme storm event. This poses a high risk to parcel owners due to the higher consequence of damage under the storm scenario evaluated for the 2100 planning horizon. 5.1.4. Critical Infrastructure There were no impacts to parcels identified as critical infrastructure for the 2050 planning horizon. A portion of a sewer pump station parcel was found to be exposed to flooding by the 2100-time horizon. This asset has sensitive electrical components and could fail should flooding of the facility occur. The pump station was assigned a moderate vulnerability since the pump station itself was not shown to be exposed to flooding. Thus, the likelihood of flooding is low and may only be expected during extreme storm events (greater than 100-year return period events). However, the flooding of the pump station has the potential Oct. 12, 2021 Item #7 Page 353 of 428 Sea Level Rise Vulnerability Assessment December 2017 14 to result in sewer spills and service interruptions. There are storm drains and culverts within Planning Zone 1, however, these facilities are not considered critical infrastructure for the purposes of this assessment (for more information refer to Appendix A, section 3.5.7). 5.1.5. Transportation Infrastructure Carlsbad Boulevard provides a vital north-south connection and will be partially exposed to flooding and bluff erosion during extreme storms in the 2050 planning horizon. Flooding exposure is localized to the Carlsbad Boulevard crossing of Buena Vista Lagoon in an area that has historically experienced flooding. Bluff erosion potential is identified along the southern portion of the Village Planning Area from about Pine Avenue to Tamarack Avenue. The bluff hazard assumes that the seawall in this area fails or is overwhelmed; thus, allowing erosion to continue landward of this feature. Although Carlsbad Boulevard is only partially exposed, the asset was assigned a moderate vulnerability in 2050 because of high sensitivity to flooding (temporary service interruptions) and low adaptive capacity. This is considered a high vulnerability in 2100 because of the vital north-south connection provided by Carlsbad Boulevard (high consequence). Vulnerability is considered high for the 2100 planning horizon as the exposure of Carlsbad Boulevard increases. The risk of this impact remains high for the 2100 planning horizon due to service interruptions or road closures that can result in traffic delays, emergency service delays and loss of evacuation routes. Damage to Carlsbad Boulevard in 2100 would also likely result in higher repair costs. 5.1.6. Environmentally Sensitive Lands Environmentally sensitive lands (e.g., lagoon, surrounding open lands, etc.) in the Buena Vista Lagoon area are exposed to increased tidal inundation as a result of sea level rise in year 2100 only because of the presence of the inlet weir structure. The weir elevation restricts tidal exchange through year 2050 planning horizon. Assuming no change to the existing condition, the weir becomes overwhelmed by year 2100 sea levels. Therefore, conditions within the lagoon remain unchanged/unaffected (no exposure and low sensitivity) by sea levels in the 2050 planning horizon. The vulnerability of environmentally sensitive lands to sea level rise in 2050 is low. By 2100, the lagoon would become subject to tides exposing environmentally sensitive lands to daily inundation (high exposure). These assets are highly sensitive to this exposure as wetland hydrology may be altered by the rising freshwater-saltwater interface (CalEMA and CNRA 2014) and intertidal and subtidal ecosystems may be affected by changes in water depth and sunlight penetration. Due to the steep topography and development along the lagoon, the ability for flora and fauna to adapt by migrating vertically and/or horizontally may be limited (low adaptive capacity). The vulnerability to environmentally sensitive lands in year 2100 is high. The vulnerability poses a high risk to the environmental resources in the city because impacts to environmentally sensitive lands are likely to occur and may adversely affect the density and diversity of these resources (high consequence). Risk of this vulnerability remains high as the consequence to density and diversity of environmental resources are significant.

PLANNING ZONE 2 Planning Zone 2 consists of two shoreline planning areas (Tamarack/Warm Water Shoreline and Terramar/ Palomar Shoreline) and the Agua Hedionda Lagoon. Assets within this zone are vulnerable to inundation, coastal flooding and bluff erosion in the 2050 and 2100 planning horizons. A summary of the vulnerability assessment rating is provided in Table 4. A discussion of the vulnerability and risk assessment is also provided for each asset category.

Beaches Approximately seven acres of beach area is projected to be impacted by inundation/erosion in 2050. As stated above, beaches are exposed to any rise in sea levels (high exposure) but will continue to provide recreation and storm protection benefits during this time horizon (low sensitivity). Beaches in this planning zone are backed by coastal structures and development; thus, have a low adaptive capacity. The overall vulnerability rating for beaches is moderate for 2050. This impact poses a moderate risk to the city because there is a high likelihood of beach loss occurring due to sea level rise, but low consequence to overall beach function based on shoreline change results from the CoSMoS 3.0 model. Oct. 12, 2021 Item #7 Page 357 of 428 Sea Level Rise Vulnerability Assessment December 2017 18 Vulnerability is rated high for the 2100 horizon due to the significant erosion expected as the beaches are squeezed between rising sea levels and bluffs or coastal structures. This vulnerability poses a high risk to the city as increased beach erosion will reduce the natural barrier to storm waves and reduce opportunity for beach access and recreation. There are also economic costs associated with such impacts; beach visitation from both in-town and out-of-town guests results in economic benefits to city businesses (e.g., retail, restaurants, hotel). 5.2.2. Public Access Ways A total of 12 vertical beach access ways exist within Planning Zone 2. A total of seven of these beach access ways were determined to be potentially impacted by coastal flooding by year 2050. All 12 were found to be vulnerable to flooding and inundation by year 2100. Lateral beach access ways in this planning area include trails along Agua Hedionda Lagoon and along Carlsbad Boulevard. Approximately 4,000 feet of existing trails were found to be vulnerable to flooding by year 2050. Approximately 15,000 feet of existing trails were vulnerable to flooding by year 2100. The vulnerability of existing trails in both planning horizons was found to be moderate, owing mostly to the relatively high adaptive capacity of these assets. Beach access ways can generally accommodate flooding and can typically be repaired relatively easily. Similarly, existing lagoon trails can accommodate some level of flooding and can be relocated when maintenance costs become too high. 5.2.3. State Parks The Tamarack State Beach parking lot becomes partially exposed to flooding during extreme storm events by 2050. The shoreline position/Inundation Hazard Zone is well seaward of the parking lot (i.e., wide sandy beach) in this scenario. State Park lands in the southern Terramar Planning Area are exposed to bluff erosion in 2050. The sensitivity of State Park lands varies in this planning area. The Tamarack State Beach parking lot has a low sensitivity and high adaptive capacity since it can tolerate episodic flooding during extreme storms while remaining functional at other times. The overall vulnerability rating for State Park lands is considered moderate due to the varied levels of sensitivity and adaptive capacity. This vulnerability poses a relatively low risk in 2050 since the consequence of episodic flooding/erosion during extreme storms will have a limited effect on access and recreational opportunities within the State Park. Exposure to flooding increases in year 2100 and complete flooding of the Tamarack State Beach parking lot can be expected during extreme storms events. The shoreline position/Inundation Hazard Zone has eroded to the existing revetment in this area by this time; thus, no beach exists in this scenario. Since shoreline erosion is projected to stop at the existing revetment line (set as non-erodible in the CoSMoS model), no erosion of the bluff landward of the parking lot occurs. Exposure to bluff erosion in the southern Terramar planning zone also increases. The overall vulnerability rating for state park lands will increase in 2100 but is still considered moderate. This vulnerability poses a moderate risk in 2100 since the consequence of more frequent flooding and erosion could result in permanent impacts to recreational opportunities within the state park. 5.2.4. Parcels A number of residential parcels in the vicinity of Terramar Point were determined to be exposed to bluff erosion hazards in the 2050 sea level rise scenario. Portions of parcels along the northern shoreline of Agua Hedionda Lagoon may also be exposed to flooding during an extreme event in year 2050 (moderate exposure). Parcels were assigned a vulnerability rating of moderate since development is typically sensitive to episodic flooding with little adaptive capacity. This vulnerability poses a moderate risk to Oct. 12, 2021 Item #7 Page 358 of 428 Sea Level Rise Vulnerability Assessment December 2017 19 parcel owners due to the high consequence of flooding impacts on parcel usage and value. The likelihood of occurrence of this type of impact is relatively low and would only be expected during extreme storm events. Vulnerability of parcels is rated high for the 2100 scenario due to the increased exposure and sensitivity of parcels to flooding and bluff erosion during an extreme storm event. Residential parcels along Terramar Point and the northern shoreline of Agua Hedionda Lagoon were found to be highly exposed to coastal hazards in 2100. The Hubbs Sea World Research Institute, the Carlsbad AquaFarm and the YMCA facility are also impacted as flood and tidal waters encroach onto these parcels. This poses a high risk to property owners due to the higher consequence of damage and disruption of operations during the 2100 planning horizon. 5.2.5. Critical Infrastructure There were no impacts to parcels identified as critical infrastructure for the 2050 planning horizon. The Encina Power Station and the desalination plant parcels were identified as being partially exposed to fluvial flooding from Agua Hedionda Lagoon as a result of sea level rise in 2100. The Encina Power Station and the desalination plant appear minimally impacted (low sensitivity) as the flooding does not appear to encroach onto critical facilities. However, confirmation of the future uses of the intake/discharge system relative to flood risks is needed to fully understand this vulnerability. Note that the Encina Power Station is scheduled to be demolished by 2020; thus, the vulnerability of this existing facility is negligible. The existing power station will be replaced with a new facility (Carlsbad Energy Center Project) that uses peaker plant technology; the new facility will be located between the railroad and Interstate 5. The Agua Hedionda Sewer Lift Station and future Carlsbad Energy Center Project (both located between the railroad and Interstate-5) are outside the coastal hazards mapped for the 2050 and 2100 scenarios. However, a project-specific sea level rise analysis may be warranted for these projects depending on specific components being proposed. Critical infrastructure was assigned a moderate vulnerability due to the low adaptive capacity and uncertainty regarding future uses of the intake/discharge system. There are storm drains and culverts within Planning Zone 2, however, these facilities are not considered critical infrastructure for the purposes of this assessment (for more information refer to Appendix A, section 3.5.7). 5.2.6. Transportation Infrastructure Approximately 4,229 linear feet of Carlsbad Boulevard within Planning Zone 2 is exposed to bluff erosion hazards during the 2050 scenario (high exposure). Carlsbad Boulevard provides a vital north-south linkage within the city; thus, its sensitivity to sea level rise is high. The adaptive capacity of the road is low since raising or relocating it may be challenging. This is considered a high-risk vulnerability because of the vital north-south connection provided by Carlsbad Boulevard (high consequence). Vulnerability remains high for the 2100 planning horizon as 15,326 linear feet of Carlsbad Boulevard are exposed to bluff erosion and flooding during an extreme storm event. The risk of this vulnerability remains high for the 2100 planning horizon due to service interruptions or road closures that can result in traffic delays, emergency service delays and loss of evacuation routes. Damage to infrastructure due to hazards identified in 2100 may result in major infrastructure repair or relocation costs. Oct. 12, 2021 Item #7 Page 359 of 428 Sea Level Rise Vulnerability Assessment December 2017 20 5.2.7. Environmentally Sensitive Lands Environmentally sensitive lands (e.g., lagoon, surrounding open lands, etc.) in the Agua Hedionda Lagoon area are exposed to increased tidal inundation and flooding with any rise in sea levels (high exposure). These assets are moderately sensitive to this exposure as wetland hydrology may be altered by the rising freshwater-saltwater interface (CalEMA and CNRA 2014) and intertidal and subtidal ecosystems may be affected by changes in water depth and sunlight penetration. Due to the steep topography and development along the Agua Hedionda Lagoon, the ability for flora and fauna to adapt by migrating vertically and/or horizontally may be limited (low adaptive capacity). This high vulnerability poses a high risk to the environmental resources in the city because impacts to environmentally sensitive lands are likely to occur and may adversely affect the density and diversity of these resources (high consequence). A high vulnerability rating was also assigned for the 2100 time horizon as adaptive capacity remains limited. However, despite the large increase in sea level rise between 2050 and 2100, the overall impacted acreage increased by less than 10%. Risk of this vulnerability remains high as the consequence to density and diversity of environmental resources are significant.

PLANNING ZONE 3 Planning Zone 3 consists of the Southern Shoreline Planning Area and the Batiquitos Lagoon. Assets within this zone are vulnerable to inundation, coastal flooding and bluff erosion in both planning horizons (2050 and 2100). A summary of the vulnerability assessment rating is provided in Table 5. A discussion of the vulnerability and risk assessment is also provided for each asset category.

Beaches Approximately 14 acres of beach area is projected to be impacted by inundation/erosion in 2050. Beaches are exposed to any rise in sea levels (high exposure) but will continue to provide recreation and storm protection benefits during this time horizon (low sensitivity). Beaches in this planning area are backed by unarmored coastal bluffs. Sand derived from the natural erosion of the bluff as sea levels rise may be adequate to sustain beach widths, thus, beaches in this reach were assumed to have a moderate adaptive capacity. The overall vulnerability rating for beaches is moderate for 2050. This impact poses a moderate Oct. 12, 2021 Item #7 Page 364 of 428 Sea Level Rise Vulnerability Assessment December 2017 25 risk to the city because there is a moderate likelihood of beach loss occurring due to sea level rise, but low consequence to overall beach function based on shoreline change results from the CoSMoS 3.0 model. Vulnerability is rated moderate for the 2100 horizon due to the significant amount of erosion expected as the beaches are squeezed between rising sea levels and bluffs. Assuming the bluffs are unarmored in the future, sand derived from bluff erosion may sustain some level of beaches in this planning area. A complete loss of beaches poses a high risk to the city as the natural barrier from storm waves is lost as well as a reduction in beach access, recreation and the economic benefits the beaches provide. 5.3.2. Public Access Ways A total of 10 vertical beach access ways exist within Planning Zone 3. Six of these beach access ways were determined to be potentially impacted by coastal flooding by year 2050. All 10 were found to be vulnerable to flooding and inundation by year 2100. Lateral beach access ways in this planning area include trails along Batiquitos Lagoon and along Carlsbad Boulevard. Approximately 5,000 feet of existing trails were found to be vulnerable by year 2050. Approximately 14,000 feet of existing trails were vulnerable by year 2100. The vulnerability of existing trails in both planning horizons was found to be moderate, owing mostly to the relatively high adaptive capacity of these assets. Beach access ways can generally accommodate flooding and can typically be repaired relatively easily. Similarly, existing lagoon trails can accommodate some level of flooding and can be relocated when maintenance costs become too high. 5.3.3. State Parks A majority of the South Carlsbad State Beach day-use facilities and campgrounds (separated into four parcels) were determined to be exposed to bluff erosion by the 2050 sea level rise scenario (moderate exposure). This resource is considered to have a high sensitivity since bluff erosion could significantly impair usage of the facilities. Though economic impacts to the physical structures within South Carlsbad State Beach would be relatively low, the loss of this park would be significant since adequate space for the park to move inland is not available (low adaptive capacity). State parks was assigned a high vulnerability in the 2050 planning horizon. State park facilities are recognized as important assets to the city in terms of economic and recreation value as well as providing low-cost visitor serving amenities. This vulnerability poses a high risk to coastal access, recreation, and tourism opportunities in this planning area. In 2100, bluff erosion of South Carlsbad State Beach day-use facilities and campgrounds become more severe and the South Ponto State Beach day-use area becomes exposed to coastal flooding during extreme events. The sensitivity of the South Ponto day-use area is low because impacts to usage will be temporary and no major damage to facilities would be anticipated. Vulnerability and risk to State Parks remains high by 2100 due to the impacts to South Carlsbad State Beach in combination with flooding impacts to South Ponto. 5.3.4. Parcels Portions of privately held parcels within Batiquitos Lagoon may be exposed to flooding during an extreme event by year 2050 (low exposure). These parcels include undeveloped lands and a golf course on the north side of the lagoon. No buildings are flooded under this scenario; thus, sensitivity is considered low. Adequate space seems to exist to accommodate sea level rise (high adaptive capacity). Overall vulnerability is considered low. Due to the relatively minor consequence and low likelihood of occurrence the risk of this vulnerability is also low. Oct. 12, 2021 Item #7 Page 365 of 428 Sea Level Rise Vulnerability Assessment December 2017 26 A total of 55 parcels were found to be impacted by year 2100. These parcels are open space, planned communities and transportation corridors. Impacted open space and planned communities are undeveloped (i.e., buildings not present), thus, vulnerability and risk to these land uses and function are considered low. Impacted transportation corridor parcels are owned by the North County Transit District. The rail line is elevated on a dike and bridged over the lagoon. Impacts to these parcels are not considered significant. 5.3.5. Critical Infrastructure No critical infrastructure is identified as vulnerable in the 2050 or 2100 years in Planning Zone 3. There are storm drains and culverts within Planning Zone 3, however, these facilities are not considered critical infrastructure for the purposes of this assessment (for more information refer to Appendix A, section 3.5.7). 5.3.6. Transportation Infrastructure Southbound Carlsbad Boulevard is exposed to bluff erosion in the vicinity of its intersection with Avenida Encinas and near Las Encinas Creek (low exposure). Bluff erosion recently resulted in emergency shore protection work along Carlsbad Boulevard in the vicinity of Las Encinas Creek. The sensitivity is high since bluff erosion hazards could significantly impact usage of transportation infrastructure. Right of way does appear available on the landward side of the southbound roadway at Las Encinas Creek. However, modifying the roadway alignment would result in significant costs (low adaptive capacity). The overall vulnerability is considered moderate at the 2050 time horizon. Damage to the southbound lanes of Carlsbad Boulevard poses a high risk due to the potential service interruptions and associated repair costs along this vital north-south connection (high consequence). Approximately 11,280 linear feet of transportation infrastructure may be exposed to bluff erosion and flooding by the 2100 scenario. This includes both northbound and southbound lanes of Carlsbad Boulevard in the vicinity of Las Encinas Creek and Batiquitos Lagoon, La Costa Avenue along the south side of Batiquitos Lagoon, and a private road within North Ponto State Beach Campgrounds. The sensitivity of all roadway segments is high because of the significant disruption to transportation circulation during these events. It is not likely that temporary flooding events will result in the need for major repairs to the roadway, but repairs due to bluff erosion could be significant. The adaptive capacity of these roadways is low since raising or relocating them would be costly. Damage to Carlsbad Boulevard from bluff erosion and flooding poses a high risk due to the potential service interruptions and associated repair costs along these routes (high consequence). 5.3.7. Environmentally Sensitive Lands Environmentally sensitive lands (e.g., lagoon, surrounding open lands, etc.) in the Batiquitos Lagoon are exposed to increased tidal inundation with any rise in sea levels (high exposure). These assets are moderately sensitive to this exposure as wetland hydrology may be altered by the rising freshwater- saltwater interface (CalEMA and CNRA 2014) and intertidal and subtidal ecosystems may be affected by changes in water depth and sunlight penetration. Due to the topography and development conditions in Batiquitos Lagoon, it is anticipated that most flora and fauna may be able to adapt by migrating vertically and/or horizontally, keeping pace with the rate of sea level rise up to 2050 (moderate adaptive capacity). The overall vulnerability of environmentally sensitive lands is moderate in 2050. The vulnerability poses a high risk to the environmental resources in the city because impacts to environmentally sensitive lands are likely to occur and may adversely affect the density and diversity of these resources (high consequence). Oct. 12, 2021 Item #7 Page 366 of 428 Sea Level Rise Vulnerability Assessment December 2017 27 Due to the steep topography and development along the lagoon, the ability for flora and fauna to adapt by migrating vertically and/or horizontally may be limited in 2100 (low adaptive capacity). Thus, a high vulnerability rating was assigned for the 2100 horizon. Despite the large increase in sea level rise between 2050 and 2100, the overall impacted acreage increased by only 6%. Risk of this vulnerability remains high as the consequence to density and diversity of environmental resources is significant.

ADAPTING TO SEA LEVEL RISE Adaptation to sea level rise, and other results of climate change, involves taking appropriate actions to prevent or minimize the adverse effects of climate-induced impacts. Adaptation planning involves a range of policies, programmatic measures and specific engineered projects that can be taken in advance of the potential impacts, or reactively, depending on the degree of preparedness, the willingness to tolerate risk, financial capacity and political acceptability. Effective adaptation planning will improve community resilience to natural disasters and climate change. Adaptation strategies, according to Coastal Commission Sea Level Rise Policy guidance (CCC 2015), generally fall into four main categories: do nothing, protect, accommodate and retreat. These strategies are generally described Section 6.1 below. When considering which strategy (or combination of strategies) is most appropriate in a particular circumstance, it is important to consider the associated secondary impacts (e.g., loss of beach resulting from the use of seawalls) and trade-offs (i.e., who/what will benefit and who/what will be adversely impacted?). Sections 6.2 and 6.3 describe the secondary impacts and trade-offs associated with the various adaptation approaches. The adaptation strategies that may be most effective in Carlsbad are then presented in Section 6.4. Many of the adaptation strategies described below can be integrated into Local Coastal Program policies and implemented through zoning regulations. 6.1. ADAPTATION STRATEGIES 6.1.1. The Do Nothing Approach Choosing to “do nothing” or following a policy of “non-intervention” can be considered an adaptive response. Doing nothing results in the need to react when sea level rise impacts occur. The reactive approach involves emergency response, attempts to maintain the status-quo and respond to impacts caused by episodic storm events and other sea level rise impacts. Reactive efforts can be more costly than other adaptation strategies, and the clean-up post disaster is often lacking in vision and leads to reconstruction of the same types of non-resilience strategies. 6.1.2. The Protection Approach Protection strategies employ some sort of engineered structure or other measure to protect or flood- proof development (or other coastal resources) in its current location without changes to the development or resources themselves. Protection strategies can be further divided into “hard” and “soft” defensive measures. Examples of a hard approach would be to construct a seawall or revetment, while a soft approach may be to nourish beaches with sand or build sand dunes. Although the California Coastal Act allows for potential protection strategies for “existing development” (i.e., development that was in existence when the Coastal Act was enacted in 1976), it also directs that new development (i.e., development after 1976) be sited and designed to avoid hazards and not require future protection that may alter a natural shoreline. When issuing a permit to allow a hard protective structure, such as a seawall, for the purpose of protecting a building or other improvement, the Coastal Commission has imposed conditions that identify when a building/improvement no longer requires protection or encroaches onto state tidelands, then the hard protective structure must be removed. Currently, much of the coastline of Carlsbad is armored with seawalls, revetment or rip rap. Documenting the age, height, condition, and permit conditions of both protective structures and the development they were built to protect will be important to determine the remaining life expectancy of protective Oct. 12, 2021 Item #7 Page 370 of 428 Sea Level Rise Vulnerability Assessment December 2017 31 structures, and the longer-term viability of maintaining these structures in a regulatory sense. Additional engineering work, including increasing the elevation of existing protective devices, and maintenance will likely be required in the future to ensure the structure effectively protects against the impacts of sea level rise. When evaluating whether or not the protection approach is an appropriate adaptation strategy, it is important to evaluate the long-term viability of protective structures and any potential impacts to coastal resources that could result if protective structures are maintained in place (see Section 6.2 for more information related to secondary impacts). It is critical to also understand the possible impacts to coastal resources that could manifest over time if protective structures are maintained in place. Passive erosion of the beach as a result of a coastal structure is one of the most significant to consider. Understanding how fast these impacts could occur, the magnitude of those impacts, and the efficacy of any measures that could mitigate those impacts is critical for determining whether – and for how long – the protection approach is appropriate for use in the city and, therefore, what policy and development standards should be included in the Local Coastal Program. Given the negative impacts of hard protective structures (as described in Section 6.2), more attention is being focused on the implementation and resulting effectiveness of soft solutions. Soft options, sometimes called living shorelines or natural infrastructure, include sediment management to reduce erosion by building wider beaches (beach nourishment) and higher sand dunes, as well as cobble placement. These soft solutions tend to mimic natural processes and can help lessen erosion and flooding while also providing habitat, water filtration and recreational opportunities. The effectiveness of soft solutions to mitigate the impacts of sea level rise is the topic of ongoing research and pilot projects. Generally, these solutions are found to be effective for shoreline protection when applied at appropriate areas. More study would be needed to determine the effectiveness of soft solutions to address sea level rise vulnerabilities in Carlsbad. 6.1.3. The Accommodation Approach Accommodation strategies employ methods that modify existing or design new developments or infrastructure in a manner that decreases hazard risks and, therefore, increases the resiliency of the development/infrastructure to the impacts of sea level rise. On an individual project scale, these accommodation strategies include actions such as elevating structures, retrofitting or using materials to increase the strength of development/infrastructure such as: the ability to handle additional wave impacts; building structures that can easily be moved and relocated; or using additional setback distances to account for acceleration of erosion. On a community scale, accommodation strategies include appropriate land use designations, zoning regulations or other measures that require the above types of actions; as well as strategies such as clustering development in less vulnerable areas or requiring mitigation actions to protect natural areas. 6.1.4. The Retreat Approach Retreat strategies relocate or remove existing development out of hazard areas and limit the construction of new development in vulnerable areas. These strategies include creating land use policies and zoning regulations that encourage building in less hazardous areas and the gradual removal and relocation of existing development as it becomes threatened or damaged. There are a variety of mechanisms to implement this approach including: acquisition and buy-out programs, transfer of development rights programs and removal of structures where the right to protection was waived (i.e., via permit condition). Oct. 12, 2021 Item #7 Page 371 of 428 Sea Level Rise Vulnerability Assessment December 2017 32 Other retreat strategies include use of conservation easements or rolling easements that limit or prohibit development in order to allow coastal erosion processes to occur into upland property; as well as hazard overlay zones that require all properties within the zone assume the risk of being in a hazardous environment, and identify triggers indicating when development needs to be relocated. 6.2. SECONDARY IMPACTS Almost all adaptation strategies have secondary impacts associated with them. Some of these are minor issues, such as short-term habitat impacts following removal of infrastructure or undergrounding of overhead power lines. Other strategies can be difficult and expensive, such as the burial of beaches under rocks following construction of revetments, or a retrofit to a critical infrastructure component. Another example of secondary impacts is the potential impacts to visual resources associated with adaptation strategies that elevate buildings or armor coastal bluffs to protect against elevated levels of flooding. The following information describes some of common secondary impacts that may result from sea level rise adaptation strategies. 6.2.1. Secondary Impacts of Doing Nothing Doing nothing can be thought of an adaptive response and one that can result in secondary impacts. Initial costs are low for this strategy; however, the long-term costs of maintenance of existing coastal structures and emergency repair of vulnerable coastal infrastructure (i.e., roadways) can be costly. Therefore, an analysis of long-term maintenance and emergency repair of existing and future vulnerable areas should be considered. Note that this analysis should include more frequent maintenance and emergency repairs over time to account for sea level rise. Coastal resources can also be impacted by doing nothing as a result of beaches and environmentally sensitive lands being squeezed between rising water levels and coastal infrastructure. Areas where these resources will change significantly or be lost by doing nothing should be considered in the long-term. The loss of beach may also lead to the loss of “towel” and recreation space, decrease in tourism, loss of beach habitat and loss of storm protection. Adopting a “do nothing” approach may limit future adaptation strategies that require long term planning for the development of funding mechanisms. 6.2.2. Secondary Impacts of Protection Strategies 6.2.2.1. Soft Protection Strategies The impacts of soft protection solutions, such as sediment management through beach nourishment and sand dunes, are generally limited to cost, as the maintenance costs of soft protection solutions can be higher than hard protective solutions. Sediment management can be costly, and ongoing sand supplies for large projects have become scarcer, which has resulted in high construction costs. Secondary impacts from sediment management vary depending on the volume, frequency and method of placing, but typically include impacts to sandy beach ecosystems, temporary recreational impacts and rocky intertidal habitat impacts. Oct. 12, 2021 Item #7 Page 372 of 428 Sea Level Rise Vulnerability Assessment December 2017 33 6.2.2.2. Hard Protection Strategies The inevitable impacts associated with hard protective solutions are commonly described within the context of the following impact categories: ❖ Placement loss – Wherever a hard structure is built, there is a footprint of the structure. The footprint of this structure results in a loss of coastal area known as placement loss. This inevitable impact can reduce the usable beach for recreation or habitat purposes. For example, a 10-foot high revetment constructed at a 2:1 slope can occupy 20 feet of usable beach for only the sloping portion of the structure. A vertical seawall or sheet pile groin typically has a smaller placement loss than a revetment or rubble mound groin. ❖ Passive erosion – Wherever a hard structure is built along a shoreline undergoing long-term net erosion, the shoreline will eventually migrate landward to (and potentially beyond) the structure. The effect of this migration will be the gradual loss of beach in front of the seawall or revetment as the water deepens and the shore face moves landward. While structures may be temporarily saved, the public beach is lost. This process of passive erosion is a generally agreed-upon result of fixing the position of the shoreline on an otherwise eroding stretch of coast, and is independent of the type of seawall constructed. Passive erosion may impact recreational beach area, as well as beach habitat area. While beach nourishment may protect the recreational value of the beach, it may not mitigate the impacts to the value and function of beach habitat. Excessive passive erosion may impact the beach profile such that shallow areas required to create breaking waves for surfing are lost. ❖ Limits on beach access – Depending on the type of structure, impacts to beach access vary. Typically, vertical beach access (ability to get to the beach) can be impacted unless there are special features integrated into the engineering design; however, as passive erosion occurs (see above), lateral (along) beach access is usually impacted. ❖ Active erosion – Refers to the interrelationship between wall and beach whereby, due to wave reflection, wave scouring, "end effects" and other coastal processes, the wall may increase the rate of loss of beach in front of the structure, and escalate the erosion rates along adjacent unarmored sections of the coast. Active erosion is typically site-specific and dependent on sand input, wave climate, specific design characteristics and other local factors. ❖ Ecological impacts – Scientific studies have documented a loss of ecosystem services, loss of habitat and reduction in biodiversity when seawall-impacted beaches were compared to natural beaches. As described above, hard protective solutions can adversely affect a wide range of coastal resources and uses, and by doing so, may conflict with the policies of the California Coastal Act, as follows: ❖ Hard protective solutions can impede or degrade public access and recreation along the shoreline by occupying beach area or tidelands and by reducing shoreline sand supply. Protecting the back of the beach with a protective structure, such as a seawall, ultimately leads to the loss of the beach as coastal erosion from sea level rise continues on adjacent unarmored sections. Where there is a protective structure the beach may drown and be lost; in contrast, where there is no hard protective structure, bluff erosion will continue and add sand supply to the beach. ❖ Hard protective solutions can also fill coastal waters or tidelands and harm marine resources and biological productivity. Oct. 12, 2021 Item #7 Page 373 of 428 Sea Level Rise Vulnerability Assessment December 2017 34 ❖ Hard protective solutions can prevent the inland migration of intertidal and beach species during large wave events. This disruption will prevent intertidal habitats, saltmarshes, beaches and other low-lying habitats from advancing landward as sea levels rise over the long-term. ❖ Hard protective solutions can degrade the scenic quality of coastal areas and alter natural landforms. The visual impact of hard protective structures and the aesthetic degradation that results from the loss of beach can have adverse economic and fiscal impacts on the local economy tied to reduced tourism and community character changes. Recent trends in coastal armoring permitting by the Coastal Commission have been to tie the coastal armoring to the structure it is required to protect, and identifying when that subject structure either no longer requires the protection or encroaches onto State tidelands. At which time, the coastal armoring is to be removed. 6.2.3. Secondary Impacts of Accommodation Strategies The primary secondary impact associated with the accommodation strategy is that it can result in impacts to visual resources and community character. Raising a building to allow for a floodable first floor can result in ocean and beach views from other portions of the city being lost. Similarly, raising coastal infrastructure or a coastal structure can impact visual resources to the public and eventually result in a change in the character of a city. Accommodation alone is not always protective of evolving coastal resources. For example, a coastal building that is raised to avoid being damaged by a future coastal storm does not protect the sandy beach. The beach will erode as sea levels rise underneath the coastal building. The beach condition underneath the building has limited function recreationally and ecologically at this state. Thus, the fate of adjacent coastal resources should be considered when considering accommodation strategies. 6.2.4. Secondary Impacts of Retreat Strategies Many communities have relied on setbacks in an effort to reduce hazard risk, and some are currently experimenting with establishing setback lines that are based on modeled predictions of the future coastline location. Setbacks alone are potentially insufficient protection and create a false sense of security because they may eventually lead to structures being at risk due to the uncertainty in the modeled predictions of the future coastline. Therefore, to be most effective at minimizing hazard risks, it is important to consider other elements of retreat, such as requiring movable foundations or identifying locations for transfer of development. Further, establishing clear triggers for action, such as relocation of development, could work in conjunction with regulatory setback policies. Finally, development located in hazardous areas should assume the risk of being located in a hazardous environment, and waive the right to any future shoreline armoring. Another example of secondary impacts from retreat strategies is cost; for example, the use of public acquisition and buy-out programs can be very costly for local, state and/or federal agencies. However, these costs should be compared against the construction and maintenance of hard engineered solutions and other adaptation approaches over the long-term. Oct. 12, 2021 Item #7 Page 374 of 428 Sea Level Rise Vulnerability Assessment December 2017 35 6.2.5. Maladaptation Adaptation measures that reduce the ability of people and communities to deal with and respond to climate change over time are called maladaptation. Maladaptation has several characteristics that help identify when it is occurring: 1) It creates a more rigid system that lead property owners and communities into a false sense of security (i.e., should one of these strategies fail, the consequences could be severe); 2) it increases greenhouse gas emissions; and 3) it reduces incentives to adapt. 6.3. UNDERSTANDING TRADEOFFS There are trade-offs associated with the various adaptation strategies, particularly in terms of “who” benefits from the adaptation strategy. For example, with hard protection strategies, like seawalls, the private property owner takes the greatest benefit through protection of their existing structures; however, as described in Section 6.2, hard protective solutions have negative impacts. The Coastal Commission has addressed these negative impacts through the use of in-lieu fees assessed for the loss of recreational beach area and sand supply. The Coastal Commission is also attempting to develop a means to calculate the replacement value of the sandy beach ecosystem. For any segment of eroding shoreline, the choice of which adaptation option to implement is affected by multiple interested parties, advisers and decision-makers, such as: ❖ Property owners; ❖ The public (i.e., community members and visitors of the beach); ❖ Experts and consultants (such as civil engineers and geologists); ❖ Government regulators, permitting and compliance officials; ❖ Special interest groups such as chambers of commerce, or non-government organizations (e.g., environmental groups, social justice); and ❖ Policy-makers or lawmakers. The motivations and constraints of the different interested parties, advisers and decision-makers vary depending on their relation to the property, their knowledge of different types of shoreline protection options, their stewardship responsibilities, their professional interests, regulatory framework, legal precedence, and local preferences. Thus, often the choice of adaptation strategy involves conflict and tension between private versus public benefits. For example, proponents of shoreline protection are usually property owners driven by a desire to preserve upland area and value or by a desire to protect, create, or restore recreational opportunities that a beach may provide. They seek an outcome that will protect and maximize their uses of the shoreline and their investment. Also, the existence of shoreline protection may reduce property insurance costs, which is another reason property owners may support construction of shoreline protection structures. Regarding private interests, a key consideration is the Public Trust Doctrine (“public trust”). Public trust ensures that the government holds title to resources for public use, such as coastal shoreline areas between the high and low tide lines (tidelands). The government is the trustee of tidelands and nearshore waters for the benefit of the public and maintains this stewardship responsibility even though some of these areas may be privately owned. The public trust has implications for all decisions regarding shoreline erosion control options that inevitably produce an impact on public trust lands. The options to benefit public trust interests vary and may also conflict. For example, some erosion control options, such as wetland creation and “living Oct. 12, 2021 Item #7 Page 375 of 428 Sea Level Rise Vulnerability Assessment December 2017 36 shorelines,” may impede the public trust interest of navigation while enhancing other public interests such as environmental quality and fishery habitat. Other erosion control options, such as breakwaters and jetties, may degrade the quality of nearshore environments (e.g., reduce their quality as fish habitat), but maintain navigation. If protecting natural shorelines, wetlands, and beaches is a priority in an area, then some erosion control options, such as vertical seawalls, may not be feasible. In other areas, protection of private or public infrastructure interests might be paramount and lead to erosion control options that conflict with conservation of natural areas. An additional issue that often complicates the subject of trade-offs is public access. Not only does common law recognize the riparian right of access to navigable waters, it also guarantees the public’s right to navigate on waters. This latter concept may create obstacles for adaptation strategies that interfere unreasonably with the public’s access to navigable waters, as well as the public navigation interest. Erosion control options, such as beach creation, may also create new opportunities for public access to the fringes of navigable waters. Sea level rise adaptation strategies may also result in conflicts and trade-offs when applying the Coastal Act to a proposed adaptation strategy. Coastal Act Section 30235 allows for the construction of shoreline protection, such as a seawall, when it is necessary to protect “existing structures” (i.e., existing when the Coastal Act was enacted in 1976) or public beaches from erosion. However, the construction of shoreline armoring may cause impacts that are inconsistent with other Coastal Act requirements; for example, Coastal Act Section 30253 prohibits new development from in any way requiring “the construction of protective devices that would substantially alter natural landforms along bluffs and cliffs.” Shoreline protective devices can also conflict with other coastal resources and uses that the Coastal Act protects, such as public access and recreation along the shoreline. 6.4. POTENTIAL ADAPTATION STRATEGIES FOR CARLSBAD 6.4.1. Adaptation Policy Strategies Chapter 7 of the Coastal Commission’s Sea Level Rise Policy Guidance describes many sea level rise adaptation alternatives. Of those, the list below represents adaptation strategies that can be considered in Carlsbad, but does not specify if a particular strategy should be applied or when and where a strategy could be implemented. As part of the city’s Local Coastal Program update, policies and regulations will be created to implement adaptation strategies that address the vulnerabilities identified in this study. When developing policies and regulations, and when determining the appropriate adaptation to implement in a given circumstance/point in time, consideration should be given to the long-term effectiveness of a particular adaptation strategy, as well as and the economic, ecological, and other potential costs/impacts. Also, when considering appropriate adaptation in a given circumstance/point in time, the assumptions and limitations of this vulnerability assessment should be considered. For example, the potential for under or over estimation of hazards may influence the geographic extent and/or timing of implementation of certain adaptation strategies. Key assumptions in this assessment, such as protective devices will not fail, should be evaluated and contingency plans developed, if applicable. If a limitation of the assessment restricts the understanding of the geographic extent of hazards, such as the removal of the weir at Buena Vista Lagoon, then the area or hazard may warrant further study as part of a future planning effort. Oct. 12, 2021 Item #7 Page 376 of 428 Sea Level Rise Vulnerability Assessment December 2017 37 Additionally, some projects will be subject to additional site specific analysis of potential sea level rise and coastal hazard impacts. Future development projects may require site specific analysis to incorporate changed conditions or to reflect the best available science regarding sea level rise and coastal hazard impacts. Based on the findings of this study, it is recommended that the city consider the following adaptation policy strategies: 1. Continue to participate in regional beach nourishment projects. Beach nourishment has been found to be an adequate approach to keep pace with low levels of sea level rise (Flick and Ewing 2009). Beach nourishment requires placement of sand from a source outside of the littoral zone; thus, providing a new source of sand to the system. Beach nourishment opportunities should continue to be pursued within Carlsbad. Continued participation and coordination with the SANDAG regional beach nourishment program should be included, as regional actions tend to provide for larger project opportunities. 2. Continue existing sand bypassing program. The beaches in Carlsbad, especially those adjacent to infrastructure (such as portions of Carlsbad Boulevard) and/or residential development, have a low adaptive capacity. Continued sand bypassing and beach nourishment projects improve the adaptive capacity rating of these beaches. Continuation of sand bypassing activities from Oceanside Harbor, which presently occur annually, is important. The city should support the continuation of this dredge bypass program. 3. Continue to implement local opportunistic sand management plan. Presently, the city has multiple sources of beach quality sand and other sediments available from local sources. It is suggested that the city continue to implement its opportunistic sand use program that identifies appropriate sediment characteristics and locations for placing the sediment to achieve the maximum benefit to recreational resources and coastal dependent uses along the city waterfront. Currently there are two routine sources of sediment in the city - Agua Hedionda Lagoon that produces 200 - 400 thousand cubic yards, on a 2-3 year cycle and Batiquitos Lagoon - that produce 50-100 thousand cubic yards, on a 4-5-year cycle. In addition, future development or restoration projects may produce additional sediment, such as the Buena Vista Lagoon restoration project. 4. Consider constructing winter berm or dune system. Residential properties in the Village Planning Area may consider a winter berm or dune system fronting their properties to provide protection during extreme events. A winter berm would protect the homes from wave run-up vulnerabilities from winter storms and could be lowered in the summer to allow for unimpeded recreational uses. A dune would be a more persistent, year-round feature that would offer similar protection. Further analysis would be needed to determine if adequate space exists and to properly size this feature. Assuming a winter berm or dune system were technically feasible and could be approved consistent with the Coastal Act on the beach fronting the Village Planning Area, a beach-wide approach would be more appropriate than implementing these on a private, per parcel basis. A geologic hazard abatement district could be established as a potential funding mechanism. The percentage share could be based on the proportional contributions made by each landowner to the construction costs. The costs could be shared based on the proportion of land frontage, or some other arrangement agreed by the landowners submitting the development application. Oct. 12, 2021 Item #7 Page 377 of 428 Sea Level Rise Vulnerability Assessment December 2017 38 5. Consider landward relocation of public assets. Consideration should be given to landward relocation of development or infrastructure in areas where adequate space exists. Carlsbad Boulevard in the vicinity of Las Encinas Creek is an example of a potential landward relocation opportunity. Consideration of landward relocation should take place at the time of planned capital improvements or after repetitive emergency repairs. The landward relocation analysis should consider the cost to maintain or protect the asset and the associated secondary impacts of doing so, versus the cost to relocate over the asset’s design life. The analysis should also consider the coastal resource and economic impact as well as the potential value of added recreational opportunities that could result from such relocation. 6. Adopt hazard overlay zones. This strategy would identify areas that are vulnerable to a set of specific hazards. Within each hazard zone, there could be a restriction on the types of development (e.g., residential), a basis for setback lines, or triggers for site-specific technical analyses or studies (e.g., geologic report triggers, slope stability analysis). 7. Require site-specific coastal hazard reports. For properties located in a coastal hazard overlay zone, this strategy would require a coastal development permit application to include a site- specific coastal hazard investigation that evaluates the exposure of the property to existing and future coastal hazards. 8. Management of prioritized existing hard shoreline protection. This strategy would employ hard protection only if allowable and if no feasible less damaging alternative exists. In some cases, caissons and pilings may also be considered hard shoreline protective devices. Under current law, shoreline protection for existing structures in danger from erosion may be allowed if coastal resource impacts are avoided or minimized and fully mitigated where unavoidable. On intensely developed, urbanized shorelines, if the removal of armoring would put existing development (in existence when the Coastal Act was enacted in 1976) at risk and not otherwise result in significant protection or enhancement of coastal resources, it may be appropriate to allow properly designed shoreline armoring to remain for the foreseeable future, subject to conditions that provide for potential future removal in coordination with surrounding development. 9. Real estate disclosures for coastal hazards. This strategy would require that upon any real estate transaction, buyers of properties in a coastal hazard overlay zone are made aware of the potential hazards to their property. This disclosure informs buyers that they may face such hazards as erosion, coastal flooding, inundation, wildfire, or flooding as a result of climate-induced impacts, such as sea level rise. It is important to note that disclosures for earthquake hazards and creek flooding already exists if a property is required to carry flood insurance. 10. Building and zoning code revisions. This approach would involve incorporating flexibility into development codes to help adapt to changes in climate. This could include limiting development in flood-prone areas, increasing building heights, using movable foundations, or requiring materials and foundations that are resistant to hazards such as fires or extreme wind. Updating height restrictions by freeboard elevation (i.e., difference in elevation between the water surface and the crest or floor of a structure), which would allow buildings to be raised for flood protection purposes, and revising the grading ordinance to reflect sea level rise projections are two examples. Structural adaptation is the modification of the design, construction, and placement of structures sited in or near coastal hazardous areas to improve their durability and/or facilitate their eventual retreat, relocation, or removal. This is often done through the elevation of structures, specific site placement, and innovative foundation construction. Oct. 12, 2021 Item #7 Page 378 of 428 Sea Level Rise Vulnerability Assessment December 2017 39 11. Develop rolling easements along the oceanfront or lagoon edge. The term “rolling easement” refers to a policy or policies intended to allow coastal lands and habitats, including beaches and wetlands, to migrate landward over time as the mean high tide line and public trust boundary moves inland with sea level rise. Such policies often restrict the use of shoreline protective structures, limit new development, and encourage the removal of structures that are seaward (or become seaward over time) of a designated boundary. This boundary may be designated based on such variables as the mean high tide line, dune vegetation line, bluff edge, or other dynamic line or legal requirement. In some cases, implementation of this can be through a permit condition (such as the “no future seawall” limitation) or purchased (such as purchasing the land between the MHW boundary and the dune vegetation line plus 5 additional feet in the landward direction so the easement can adjust with sea level rise). 12. Fee simple acquisition. This approach is the purchase of vacant or developed land in order to prevent or remove property from the danger of coastal hazards such as erosion or flooding. One such example of this adaptation strategy is to purchase properties at risk and to demolish structures and restore habitats and physical processes, as has been done in Pacifica, California. A hybridized version of this adaptation strategy may be a public acquisition program in which an entity purchases the hazardous property and then leases the land back to the previous landowner with the deed restriction and understanding that when the structure or parcel is damaged that the lease may expire. 13. Require special considerations for critical infrastructure and facilities. Addressing sea level rise impacts to critical facilities and infrastructure (e.g., roads, bridges, water, sewer facilities, etc.) will likely be more complex than for other resources and may require greater amounts of planning time, impacts analyses, public input, and funding. To address these complexities, the city could establish measures that require continued function of critical infrastructure, or the basic facilities, service, networks, and systems needed for the functioning of a community. Programs and measures within a Local Coastal Program could include identification of critical infrastructure that is vulnerable to sea level rise hazards, establishment of a plan for managed relocation of at-risk facilities, and/or other measures to ensure functional continuity of the critical services provided by infrastructure at risk from sea level rise and extreme storms. Repair and maintenance, elevation or spot-repair of key components, or fortification of structures where consistent with the California Coastal Act may be implemented through coastal development permits. 14. Limit redevelopment or upgrades to existing legal non-conforming structures in at-risk locations. The city could develop and enforce policies and regulations that define non-conforming development in coastal hazard zones and place limits on expansion, redevelopment, or upgrades to legal non-conforming structures. These may require redevelopment proposals to comply with requirements for new development, including regulations that minimize sea level rise hazards; also, deed restrictions or other mechanisms could be required to notify existing and future property owners about such limitations. 15. Continue to monitor beaches. The city’s existing beach monitoring program provides a long-term record of beach width change in Carlsbad. It is recommended that this program be continued into the future to track local beach response to sea level rise. As part of this program, it is also recommended that storm events be documented through photographs and field notes. This documentation will assist in validation of the numerical modeling results and to track the frequency of these events. Oct. 12, 2021 Item #7 Page 379 of 428 Sea Level Rise Vulnerability Assessment December 2017 40 16. Periodically update this Sea Level Rise Vulnerability Assessment. Update this assessment when significant changes in climate science or coastal hazard mapping methods occur. Addenda to this document could be an approach to capture these updates. 17. Develop a coastal armoring database and action plan. The city could create a database of the status and condition of existing armoring in the city. The database can build off the GIS database developed for this study and should be compatible with the redesigned coastal armoring database developed by the California Coastal Commission. A coastal armoring database will provide the city to with an inventory of the age, type and condition of coastal structures in the city as well as similar information about the structure or asset the armoring serves to protect. This data is important for future decision making and implementation of future Local Coastal Program policies related to sea level rise adaptation. 18. Revise development setbacks. Existing building setback requirements should be revised to account for accelerated erosion caused by increasing sea levels and hours of wave attack, as well as a factor of safety distance that is related to the erosion mechanism (e.g., dune erosion versus cliff erosion). The setback should factor in the life expectancy of the proposed development or redevelopment. For example, in a bluff-backed shoreline, where historic failures have shown to be capable of a 30-foot failure, the setback should include accelerated erosion rates in addition to a failure distance that could occur at the end of the development’s life expectancy. 19. Develop a repetitive loss program. One way to implement managed retreat would be to develop a repetitive loss program that could include the following strategies in response to requests to repair property damaged by sea level rise related storm damage: 1) permit the first request to repair storm damage; 2) when a property is damaged a second time, permit the repairs and apply zoning limitations or a zone change that precludes future development/improvements on the property or the portion of the property that is vulnerable to sea level rise impacts; and 3) when a property is damaged a third time, repairs would not be permitted unless it is demonstrated that the repairs will remove the structure/property from future hazard. 20. Identify triggers to shift implementation to different adaptation strategies. Over time, the city may implement all or most of the potential adaptation strategies, likely in the following order: protect, accommodate, and retreat. Given the uncertainty in timing and severity of impacts, it is important to identify triggers, which once reached, will commence planning and implementation actions for the next set of adaptation strategies. Triggers can vary widely, but generally fall into four categories: a. By sea level rise elevation or rate of sea level rise observable at tide gages. b. By time, such as upon closure of the once through cooling power plants. c. By exposure, such as how frequently Carlsbad Boulevard is closed to travel due to wave action. d. By damages, such as a structure needs to be removed once it is damaged by more than 50% or has multiple insurance claims for flood damages. To be effective, these triggers should be implemented through specific measurable metrics with clear direction on what should happen once a threshold is triggered. Oct. 12, 2021 Item #7 Page 380 of 428 Sea Level Rise Vulnerability Assessment December 2017 41 Carlsbad Boulevard is an example of an asset vulnerable to sea level rise in different locations along the roadway, and it may be necessary to implement different adaptation strategies over time. The following describes the areas of the roadway that may become vulnerable to sea level rise over time: • The far northern stretch of the road that crosses Buena Vista Lagoon; to adapt raising that portion of the roadway above the level of vulnerability may be necessary. • Portions of the road in Planning Zones 1 and 2; to adapt, additional coastal armoring with raised seawalls may be appropriate to protect the road. • Portions of the road in the southern shoreline area of Planning Zone 3; to adapt construction of a dune restoration or cobble berm may be an appropriate strategy. 6.4.2. Adaptation Project Strategies This section generally describes the types of adaptation projects that would be effective in minimizing coastal hazards within geographic areas that are vulnerable to sea level rise, which include Carlsbad’s low- lying beaches, low-lying estuaries, and the bluff-backed shoreline segments. 6.4.2.1. Low-Lying Beaches Low-lying beaches are exposed to coastal hazards related to wave flooding, coastal erosion, stormwater coastal confluences (rainfall runoff trapped by high tides and sea level rise), and eventually tidal inundation. Carlsbad’s low-lying beaches are predominately within the northern portion of the Village Planning Area. To adapt to these coastal hazards, the following types of adaptation projects are likely to be most effective and are listed in order of soft strategies to hard strategies: ❖ Managed retreat (soft) o Landward relocation of public assets o Hazard overlay zones o Real estate disclosures o Rolling easements o Fee simple acquisition o Limit redevelopment/upgrades o Repetitive loss program ❖ Sand retention with nourishment (soft) o Regional beach nourishment o Sand bypassing o Sand management plan o Winter berm or dune ❖ Dune restoration (soft) ❖ Elevating structures (hard) ❖ Beach nourishment (soft) ❖ Coastal armoring (hard) Oct. 12, 2021 Item #7 Page 381 of 428 Sea Level Rise Vulnerability Assessment December 2017 42 6.4.2.2. Low-Lying Estuaries Low-lying estuaries are exposed to coastal hazards of stormwater confluences (rainfall runoff trapped by high tides and sea level rise) and increasing tidal inundation. These areas include Buena Vista Lagoon, Aqua Hedionda Lagoon and Batiquitos Lagoon. To adapt to these coastal hazards, the following types of projects are likely to be most effective and are listed in order of soft strategies to hard strategies: ❖ Managed retreat (soft) o Landward relocation of public assets o Hazard overlay zones o Real estate disclosures o Rolling easements o Fee simple acquisition o Limit redevelopment/upgrades o Repetitive loss program ❖ Dune or wetland restoration (soft) ❖ Elevating structures (hard) ❖ Coastal armoring (hard) 6.4.2.3. Bluff-Backed Shoreline Most of the Carlsbad shoreline is bluff-backed, which includes much of Terramar and the Southern Planning Areas. In bluff-backed shoreline reaches, the physical processes causing the vulnerabilities are largely due to wave velocity, erosion of the bluffs, some minor coastal flooding along low lying bluffs, and acceleration of bluff erosion in the future as sea levels rise. Of particular concern, bluff-backed shoreline segments provide public access, as well as state park campgrounds. To adapt to the coastal hazards in the bluff-backed shoreline reaches, the following types of projects are likely to be the most effective and are listed in order of soft strategies to hard strategies: ❖ Managed retreat (soft) o Landward relocation of public assets o Hazard overlay zones o Real estate disclosures o Rolling easements o Fee simple acquisition o Limit redevelopment/upgrades o Repetitive loss program ❖ Movable foundation (soft/hard hybrid) ❖ Coastal armoring (hard) 6.4.3. Adaptation Strategy Costs The monetary and non-monetary costs associated with the various adaptation strategies should be considered when developing adaptation policies and regulations. An example of non-monetary costs is the loss of san supply and recreation opportunities that may result from the construction of hard protective structures. The monetary cost to construct and maintain hard protective structures can be significant, and consideration of the initial construction and periodic maintenance costs should be evaluated over time to develop life-cycle cost of a coastal armoring strategy. When planning for sea level rise, the life-cycle cost to protect should be compared to the cost of the asset being protected or cost to relocate that asset. As an example of construction and maintenance costs, the rough order of magnitude costs (in 2017 dollars) of common protection strategies are provided in Table 6.

CONCLUSIONS AND RECOMMENDATIONS The purpose of this vulnerability assessment was to identify assets and planning areas at risk to future rates of sea level rise within Carlsbad. The study considered vulnerabilities to flooding, inundation and bluff erosion as a result of two sea level rise scenarios (2050 and 2100) as predicted by preliminary results from CoSMoS 3.0 and supplemental fluvial flooding zones generated by Moffatt & Nichol. Although the scientific community has identified that ocean levels will rise in the future, there remains uncertainty regarding the timing and magnitude of these future conditions. Appendix A includes more information on how each assumption or limitation of the model may result in under or over estimations of hazards. The results of the vulnerability assessment are summarized in Table 7. Table 7: City-Wide Sea Level Rise Vulnerability Summary Asset Category Horizon Impacted Assets Overall Vulnerability Rating (Low - High) Beaches 2050 27 acres Moderate 2100 146 acres High Public Access Ways 2050 26 beach access ways 2.6 miles of lateral access ways Moderate 2100 37 beach access ways 7.3 miles of lateral access ways Moderate State Parks 2050 6 Parcels Moderate - High 2100 6 Parcels Moderate - High Parcels 2050 564 Parcels Moderate 2100 657 Parcels High Critical Infrastructure 2050 0 Parcels Low 2100 8 Parcels Moderate Transportation 2050 1.6 miles High 2100 5.8 miles High Environmentally Sensitive Lands 2050 1,088 acres Moderate 2100 1,164 acres High The results of the vulnerability assessment, as based on the USGS CoSMoS 3.0 modeling outputs, are described by asset type below: ❖ Beaches – Beach erosion impacts do not appear significant until year 2100. Carlsbad beaches were found to lose 146 acres of shoreline by this time horizon. The loss of beach results in numerous adverse impacts, including reduction of beach “towel space” or recreational area for visitors and residents, reduction of coastal public access, loss of coastal habitat and ecological value, and impacts to the beach’s ability to function as a natural storm buffer. In addition, the loss of beaches has been found to result in direct and indirect economic impacts; direct impacts are a byproduct of the protection that they provide to coastal infrastructure; and indirect impacts are a result of a reduction in visitation from residents and visitors, which would then impact visitor-serving businesses. The overall vulnerability of beaches by year 2050 is considered moderate. Oct. 12, 2021 Item #7 Page 384 of 428 Sea Level Rise Vulnerability Assessment December 2017 45 ❖ Public Access Ways – Coastal flooding and erosion has the potential to impact vertical (access to) and lateral (access along) beach access ways in the city. A total of 37 vertical beach access ways exist in the city. All of these access ways were determined to be vulnerable to flooding and inundation by year 2100. About three quarters of these access ways were vulnerable to flooding during the 2050 time horizon. About 7 miles of lateral access ways (trails) were found to be vulnerable by year 2100. The public access ways exist along the beach and lagoons in the city. About 2.5 miles of trails are vulnerable to flooding in the 2050 time horizon. The overall vulnerability of public access ways in year 2050 was determined to be moderate. ❖ State Parks – Though state parks are not owned or operated by the city, they provide a valuable asset to the city by providing recreation and a low-cost visitor serving amenity. State parks are most at risk in Planning Zones 2 and 3 where beaches, campgrounds (South Carlsbad and Ponto) and day-use parking facilities are within coastal hazard zones. The primary coastal hazard is bluff erosion, which may result in the loss or partial loss of campsites and day use facilities. The overall vulnerability to this asset by year 2050 is considered moderate-high. ❖ Parcels – The majority of the parcels at risk are in Planning Zones 1 and 2, where 515 parcels were found to be impacted by the 2050 sea level rise scenario. The parcels that are at risk to flooding and bluff erosion are located on coastal and lagoon-front properties in these planning zones. The most parcels at risk are in Planning Zone 2, where 451 parcels were found to be at risk by 2100. The overall vulnerability to this asset by year 2050 is considered moderate. ❖ Critical Infrastructure – Critical infrastructure was found to be at risk to sea level rise in Planning Zones 1 and 2. Critical infrastructure was limited to sewer pump stations and the commercial uses adjacent to the Agua Hedionda Lagoon. The overall vulnerability to these assets by year 2100 is considered moderate. The overall vulnerability to this asset by year 2050 is considered low due to no parcels being impacted. ❖ Transportation – Transportation infrastructure in all planning zones was found to be at risk to flooding and bluff erosion by year 2050. Carlsbad Boulevard was determined to be the most vulnerable due to the critical north-south linkage it provides; however, La Costa Avenue, Jefferson Street, and private roads within state parks campgrounds were also found to be vulnerable. The overall vulnerability to this asset by year 2050 is considered high. ❖ Environmentally Sensitive Lands – Environmentally sensitive lands include wetlands, riparian areas, coastal prairies, woodlands and forests, and other natural resources in the coastal zone. Planning Zone 3 had the most environmentally sensitive lands at risk to flooding with a total of 606 acres at risk by year 2100. Due to the steep topography and development along much of the lagoon shorelines in Carlsbad, the ability for flora and fauna to naturally adapt by migrating vertically and/or horizontally may be limited. The overall vulnerability to this asset by year 2050 is considered moderate. Oct. 12, 2021 Item #7 Page 385 of 428 Sea Level Rise Vulnerability Assessment December 2017 46 To address identified vulnerabilities, the adaptation measures described in this report provide a range of available options for the city to consider in the development of its Local Coastal Program update. These potential adaptation options are as follows: ❖ Continue to participate in Regional Beach Nourishment Projects ❖ Continuation of Sand Bypassing Program ❖ Continue to implement local opportunistic sand management plan ❖ Construct winter berm or dune system ❖ Landward relocation of public assets ❖ Adopt Hazard Overlay Zones ❖ Require site-specific coastal hazard reports ❖ Management of prioritized existing hard shoreline protection ❖ Real estate disclosures for coastal hazards ❖ Building and zone code revisions ❖ Develop rolling easements along the oceanfront bluff edge ❖ Fee simple acquisition of vulnerable properties ❖ Require special considerations for critical infrastructure and facilities ❖ Limit redevelopment or upgrades to existing legal non-conforming structures in at-risk locations ❖ Continue to monitor beaches ❖ Periodically update Vulnerability Assessment ❖ Develop a coastal armoring database and action plan ❖ Revise development setbacks ❖ Develop a repetitive loss program ❖ Identify triggers to shift implementation to different adaptation strategies. Triggers may include sea level elevation, time, exposure or damage. Generally, the shoreline areas in Carlsbad that are vulnerable to sea level rise include: low lying beaches, low lying estuaries, and bluff-backed shoreline. Current and future coastal hazard vulnerabilities to these shoreline segments vary and, likewise, the most effective adaptation responses differ. The following types of adaptation responses are the most effective for the respective shoreline type and are listed in order of “soft” to “hard” strategies: ❖ Low lying beaches ➢ Managed retreat ➢ Dune restoration ➢ Beach nourishment ➢ Sand retention with nourishment ➢ Elevating structures ➢ Coastal armoring ❖ Low lying estuaries ➢ Managed retreat ➢ Dune or wetland restoration ➢ Elevating structures ➢ Coastal armoring ❖ Bluff-backed shoreline ➢ Managed retreat ➢ Movable foundation ➢ Coastal armoring Oct. 12, 2021 Item #7 Page 386 of 428 Sea Level Rise Vulnerability Assessment December 2017 47 8.

SEA LEVEL RISE SCIENCE AND PROJECTIONS Sea levels are projected to rise in the coming decades as a result of increased global temperatures associated with climate change (Intergovernmental Panel on Climate Change 2013). When discussing sea level rise (and when reviewing sea level rise projections), it is important to distinguish the differences between global and local sea level rise rates. Global sea level rise rates disregard local effects such as tectonics (i.e., land uplift/subsidence), water temperatures, and wind stress patterns that can act to subdue or amplify the global sea level rise rates. Local (or relative) sea level rise refers to the observed changes in sea level relative to the shoreline in a specific region and takes into account these local factors. It should be noted that guidance related to sea level rise evolves as new science is released. The most relevant science and guidance from the international, federal, and state levels at the time of this report is summarized in this section. 1.1. STATE GUIDANCE The 2012 National Research Council report titled “Sea-Level Rise for the Coasts of California, Oregon, and Washington: Past, Present, and Future,” is considered the best available science for California (CCC 2015, CO-CAT 2013). Thus, both state guidance documents utilize the sea level rise projections from the National Research Council’s report. The National Research Council is a conglomerate of scientists and research organizations that act as an advisory group for government agencies. 1.1.1. California Coastal Commission Sea Level Rise Policy Guidance (CCC 2015) The document states that the best available science should be utilized when incorporating sea level rise into planning documents or when applying for a coastal development permit. As stated above, the 2012 National Research Council’s report is generally considered as the best available science for the region at the time of this report. The 2012 National Research Council’s report predicts a 0.9-ft increase of relative sea level rise (i.e., relative rise of the ocean water level compared to land) by 2050 and a 3.1-ft increase by 2100 in the City (Table 1). These projections are described as being applicable to all areas south of Cape Mendocino in the study. The sea level rise projection values in Table 1 indicate the mean and uncertainty (i.e., standard deviation) for a specific IPCC future greenhouse gas emission scenarios (i.e., A1B). The A1B scenario represents a world of rapid economic growth and a balanced use of fossil and non-fossil energy sources. The sea level rise ranges in Table 1 represent the means for the B1 (low greenhouse gas emission scenario) and A1FI (high greenhouse gas emission scenario). Note that the certainty in projections decrease with time, as indicated by the increasing uncertainty values. Table 1: Sea Level Rise Projections for Los Angeles Region Year Projected Sea Level Rise (ft.) Projection Uncertainty (ft., +/-) Low Range (ft.) High Range (ft.) 2030 0.5 0.2 0.2 1.0 2050 0.9 0.3 0.4 2.0 2100 3.1 0.8 1.5 5.5 (Source: National Research Council 2012) Oct. 12, 2021 Item #7 Page 389 of 428 Sea Level Rise Vulnerability Assessment December 2017 A-3 1.1.2. State of California Sea-level Rise Guidance Document (CO-CAT 2013) A state sea level rise guidance document, titled “State of California Sea-Level Rise Guidance Document (Interim Guidance)” (CO-CAT 2013), was originally released in October 2010 and re-released/updated in March 2013 to provide guidance to state agencies for incorporation of sea level rise projections into project planning and decision making. The document recommended use of the ranges of sea level rise presented in the 2012 National Research Council’s report as a starting place. CO-CAT recommends that specific project design sea level rise scenario ranges should then be based on agency- and context-specific considerations of risk tolerance and adaptive capacity of the affected assets. The Ocean Protection Council intends to update the state sea level rise guidance in early 2018 to reflect new research on sea level rise projections. This vulnerability assessment will be periodically updated and the guidance in effect at the time of the update will be utilized. 2. COASTAL SETTING 2.1. WATER LEVELS The nearest, long-term sea level record in proximity to the study area is the La Jolla tide gage (Station 9410230) operated by the National Oceanic and Atmospheric Administration (NOAA). The gage is located on the Scripps Pier, which has been collecting data since 1924. These data are applicable to the San Diego region open-ocean coastline and are summarized in Table 2. Table 2: Water Levels in La Jolla (1983-2001 Tidal Epoch) Description Datum Elevation (ft MLLW) Highest Observed Water Level (1/11/2005 5:00:00 PM) Maximum 7.66 Highest Astronomical Tide HAT 7.14 Mean Higher-High Water MHHW 5.32 Mean High Water MHW 4.60 Mean Sea Level MSL 2.73 Mean Low Water MLW 0.90 Mean Lower-Low Water MLLW 0.00 North American Vertical Datum of 1988 NAVD88 0.19 Lowest Astronomical Tide LAT -1.88 Lowest Observed Water Level (12/17/1933 11:36:00 PM) Minimum -2.87 (Source: NOAA 2015) 2.2. LITTORAL PROCESSES A littoral cell is a segment of shoreline in which sand is bounded or contained. The City is located within the Oceanside Littoral Cell, which extends from Dana Point Harbor to La Jolla, a distance of approximately 50 miles (Patsch and Griggs 2007). The cell’s shoreline consists of a narrow beach that is backed by seacliffs, bluffs, and mouths of coastal streams and rivers. Inputs to the Oceanside Littoral Cell include: fluvial sources (rivers), bluff erosion, gully and terrace erosion, and anthropogenic sources (i.e., beach nourishment). Natural sand loss occurs at sand sinks, which include the La Jolla and Scripps submarine canyons, lagoons, and offshore bars (Patsch and Griggs 2007). Oct. 12, 2021 Item #7 Page 390 of 428 Sea Level Rise Vulnerability Assessment December 2017 A-4 Human intervention has significantly influenced the coastal processes in the Oceanside Littoral Cell. The construction of coastal structures (i.e., jetties, seawalls, etc.) and inland flood control structures (i.e., dams) have reduced the amount of sand traveling along the coast and being delivered to the coast, respectively. In particular, the Oceanside Harbor jetty system effectively traps sand from naturally traveling from north to south. The harbor captures sand, which is dredged and placed on downdrift beaches. This is approximately equal to the net littoral drift from Oceanside Harbor to Scripps Submarine Canyon (Patsch and Griggs 2007). The City currently monitors the beaches by measuring beach profiles throughout the city at historic beach profile locations. Beaches have been monitored at 12 sites for 20 years. Data from the monitoring indicate that Carlsbad beaches are relatively stable, with seasonal shifts in beach width and gains associated with beach nourishment or bypassing projects. Specifically, North Carlsbad Beach is relatively stable due to the effects of periodic nourishment from the Regional Beach Sand Projects (RBSPs), and from more regular nourishment from maintenance dredging and bypassing in and around Agua Hedionda Lagoon. Beaches south of the Agua Hedionda Lagoon mouth (middle beach) vary, with stability from sand placed as part of the lagoon maintenance dredge material placed between the inlet jetties. Beaches south of Terramar Point through the Southern Planning Area are actively eroding, with periodic widening from San Diego Association of Governments (SANDAG) sand replenishment projects (see Section 2.4, below) followed by narrowing. Farthest to the south, the beaches on both sides of the Batiquitos Lagoon mouth are relatively wide due to the sand retention effects of the lagoon mouth jetties, from benefits of nourishment from initial 1995 lagoon restoration, and from on-going maintenance dredging of the lagoon since approximately 2005. 2.3. WAVES Waves act to carry sand in both the cross-shore and longshore directions and can also cause short- duration flooding events by causing dynamic increases in water levels. Thus, the wave climate (or long- term exposure of a coastline to incoming waves) and extreme wave events are important in understanding future sea level rise vulnerabilities. Offshore wave data was analyzed for Carlsbad from Wave Information Studies (WIS) Station 83105 from 1980 to 2011 (Figure 1). WIS, developed by the USACE, is an online database of estimated nearshore wave conditions covering U.S. coasts. The wave information is derived based on a database of collected wind measurements (a process known as wave “hindcasting”) and is calibrated by offshore wave buoys. The hindcast data provides a valuable source of decades-long nearshore wave data for coastlines in the U.S. Oct. 12, 2021 Item #7 Page 391 of 428 Sea Level Rise Vulnerability Assessment December 2017 A-5 Figure 1: Location of WIS Station 83105 2.3.1. Wave Climate The largest percentage (36%) of the waves approaching Carlsbad are from the west (270 degrees). The most frequent wave height is 1.5 to 3 ft., as shown in Figure 2. Wave periods were between 12 and 16 seconds with 14 to 15 seconds occurring the most frequently (Figure 3). 2.3.2. Extreme Waves The 50- and 100-year return period wave heights in Carlsbad are approximately 19.6 and 22 ft, respectively (Figure 3). The largest waves occur in the winter when northern hemisphere cyclonic storms generate powerful, long period waves. These waves can result in coastal erosion, flooding and bluff failures.

SHORELINE MANAGEMENT In addition to dredging projects along the Oceanside Littoral Cell coast, periodic beach nourishment projects have added to the sediment budget. The City of Carlsbad has actively participated in the Shoreline Preservation Working Group within SANDAG since its inception as the Shoreline Erosion Committee in 1991. SANDAG issued its Shoreline Preservation Strategy in the early 1990s that called for pilot beach nourishment projects to restore the region’s beaches (SANDAG 1993). The two RBSPs in the city were implemented as RBSP I in 2001 and RBSP II in 2012 that included sand placed at two beach locations along Carlsbad’s coastline. The city’s other sand management activities include coordinating with the sand bypassing by Encina Power Station at Agua Hedionda Lagoon. At the request of the city, the sand from the lagoon entrance is placed on the beach both north and south of the jetties. City leaders work through an appointed Beach Preservation Committee that makes recommendations regarding sand management. As mentioned above, the city has also participated in two RBSPs. One of the sites was located at North Carlsbad Beach, just south of the Buena Vista Lagoon mouth, and the other site was located at South Carlsbad North just north of the mouth of Las Encinas Creek. Sand from other placement sites adjacent to Carlsbad (i.e., Oceanside and Encinitas) also moved both up and down the coast to benefit the city. 2.5. SHORELINE ARMORING Shoreline armoring exists along much of the city’s coastline, though is concentrated along the north coastline. Armoring consists of seawalls, revetments, and rip rap, as shown in Figure 4. A shoreline armoring GIS shapefile was created for the city to inventory the presence and type of shoreline structures. This file was based on a prior shoreline armoring database created by the Coastal Commission in 2005 (Dare 2005). The database was revised to include proper structure type (where applicable) and improved to be spatially explicit. The Dare 2005 database was previously set to an arbitrary, straight offshore line in the city. This line was revised to represent the approximate location of coastal structures in the city. The legality, age, and state of repair of the structure was not detailed as part of this effort. Oct. 12, 2021 Item #7 Page 394 of 428 Sea Level Rise Vulnerability Assessment December 2017 A-8 Figure 4: Shoreline Armoring in Carlsbad Oct. 12, 2021 Item #7 Page 395 of 428 Sea Level Rise Vulnerability Assessment December 2017 A-9 3. COASTAL HAZARD MODELING AND MAPPING Carlsbad’s exposure to future rates of sea level rise was determined using preliminary results from the CoSMoS 3.0 model. CoSMoS is a multi-agency effort led by the U.S. Geological Survey (USGS) to make detailed predictions (meter scale) of coastal flooding and erosion based on existing and future climate scenarios for Southern California. The modeling effort depicts coastal flooding, shoreline change and bluff response to a composite, 100-year wave event in combination with various rates of sea level rise and baseline water levels (i.e., high tide, storm surge, sea level anomaly and river discharge). Details on the sea level rise scenarios selected and how the respective coastal hazards were mapped are provided in this section. 3.1. SEA LEVEL RISE SCENARIOS Years 2050 and 2100 were selected as planning horizons for this vulnerability assessment. The CoSMoS 0.5 m and 2 m sea level rise scenarios roughly align with the projected high sea level rise from the 2012 National Research Council’s report for the 2050 and 2100 planning horizons. Therefore, these sea level rise scenario results were used as the basis for this vulnerability analysis. The National Research Council’s high range projection is slightly higher (0.3 ft.) for year 2050 and slightly lower (1.1 ft.) for year 2100 compared to CoSMoS projections. Thus, the hazards predicted by CoSMoS projection for 2050 will be marginally less than hazards resulting from the National Research Council’s projection and the hazards for 2100 will be greater as predicted by CoSMoS projections compared to the National Research Council projections. A comparison of the National Research Council’s 2012 sea level rise projections for the planning horizons compared to the CoSMoS scenarios used is shown in Table 3. Table 3: Comparison of Sea Level Rise Scenarios Year 2012 National Research Council Sea Level Rise Projections CoSMoS 3.0 Sea Level Rise Scenario Difference (CoSMoS vs. 2012 National Research Council) (ft.) Projection (ft.) Uncertainty Low Range (ft.) High Range (ft.) (ft., +/-) 2050 0.9 0.3 0.4 2 0.5 m (1.7 ft.) 0.3 2100 3.1 0.8 1.5 5.5 2.0 m (6.6 ft.) 1.1 3.2. BLUFF EROSION Projections of coastal cliff-retreat rates (or cliff erosion rates) and positions for future sea level rise scenarios were made using numerical and statistical models based on field observations such as historical cliff retreat rate, submarine slope, coastal cliff height, and mean annual wave power (CoSMoS 2015). Bluff profile evolution models relate breaking-wave height and period to bluff erosion, and distribute erosion vertically over a tidal cycle. The above modeling approach was run assuming a bluff edge baseline established from the 2010 digital elevation model. Determining the bluff edge is a subjective process and spatial projections will depend on the interpretation of the bluff edge. The bluff hazard zone for each projection year was shown as the area between the baseline bluff positon and the projected bluff position for the 0.5 m and 2.0 m sea level rise scenarios. Bluff erosion rates are based on historical rates from the USGS National Assessment of Shoreline Change and assume that sea level rise does accelerate erosion. Figure 5 provides a schematic depicting the projected CoSMoS 3.0 bluff erosion results for various sea level rise scenarios (shown as blue to red polylines) and uncertainty limits for the 2.0 m scenario (shown as a light grey). Oct. 12, 2021 Item #7 Page 396 of 428 Sea Level Rise Vulnerability Assessment December 2017 A-10 Figure 5: CoSMoS Bluff Erosion Projections by 2100 (CoSMoS-COAST 2015) 3.3. COASTAL FLOODING The CoSMoS model is comprised of three tiers that transform the offshore wave climate to the shoreline and inland. Tier I contains two models: a hydrodynamics (motions and forces of fluids) flow model (Delft 3D) that computes tides, water level variations, flows, and currents; and a wave generation and propagation model (SWAN). Tier II refines the resolution of the model by segmenting the Southern California Bight (coastline from Point Conception to San Diego) area into 11 sections and incorporating fluvial discharge through the FLOW model to simulate flooding from elevated water (coastal and river) levels. Tier III uses the XBeach model to run hydrostatic, morphodynamic (water and beach interaction and resulting adjustments and changes) simulations. The resulting projected flood hazards mapped are areas vulnerable to coastal flooding due to storm surge, sea-level anomalies (e.g., higher water levels due to warm water temperatures or low atmospheric pressure), tide elevation, and wave run-up during the 2100 storm simulation in combinations with the maximum elevation of still-water level. 3.4. SHORELINE EROSION Projections of shoreline change as a result of future sea level rise scenarios were made using CoSMoS- COAST model (Figure 6). This shoreline model uses a series of global-to-local nested wave models (such as WaveWatch III and SWAN) forced with Global Climate Model (GCM) derived wind fields. Historical and projected time series of daily maximum wave height and corresponding wave period and direction from 1990 to 2100 force the shoreline model (CoSMoS-COAST 2015). Additionally, the CoSMoS-COAST model incorporates the following relevant processes in sediment transport: longshore transport and shoreline equilibrium equations; wave-driven cross-shore transport and resulting equilibrium beach profiles; and long-term beach profile changes due to sea level rise. Light detection and ranging (LIDAR) data is then used to adjust the model parameters in an effort to estimate the effects of unresolved processes, such as natural and anthropogenic (beach nourishment and bypassing) sediment supply.

MODEL LIMITATIONS The preliminary CoSMoS 3.0 release is a useful dataset for the first-order identification of future at-risk areas. The data is preliminary; therefore, is subject to revision prior to being finalized in 2017. However, even when the final CoSMoS product is released, due to the regional nature of the modeling exercise, city- scale details can be lost. Other limitations of the CoSMoS 3.0 data set are discussed in this section. 3.5.1. Topographic / Bathymetric Model Resolutions CoSMoS developed a seamless, topo-bathymetric digital elevation model combining land based topographic elevation data with below water bathymetric elevation data, which was based on bare-earth LIDAR data collected in 2009-2011 for the California Coastal Conservancy LIDAR Project, bathymetric LIDAR from 2009-2010 as well as acoustic multi- and single-beam data collected primarily between 2001 and 2013. Though this data was the best-available to the study team, some local-scale details in the city were lost in this data set (e.g., vertical seawalls). Oct. 12, 2021 Item #7 Page 398 of 428 Sea Level Rise Vulnerability Assessment December 2017 A-12 3.5.2. Bluff Erosion (Bluff Hazard Zone) The CoSMoS model makes regional assumptions using a uniform bluff substrate, meaning that the bluff is assumed to be made up entirely of the same sediment; thus, oversimplifies many bluffs in San Diego County that consist of multiple sediment layers of varying erosive tendencies, the degree of prediction provided by these assumptions is unknown. The modelers cited a sparsity of data on bluff substrate as the reason for this assumption. The model used the USGS National Shoreline Assessment study for data on historical bluff retreat. This study analyzed bluff change from about 1933 to 1998 and found that bluffs within the Oceanside region, which captures the City of Carlsbad, are retreating at an average rate of 0.7 ft. per year. The accuracy of these bluff erosion predictions is dependent on the deviation from the uniform bluff substrate assumed at each bluff location. These historic erosion rates which account for acceleration due to sea level rise, however may underestimate the effects of sea level rise on erosion over time. The model did not include shoreline protection structures in the city. Examples of bluff protection structures that were excluded include coastal structures (seawalls, revetments, riprap) and bluff stabilization treatments that exist in the community of Terramar. The model states that coastal structures were not included if the armoring was low enough to be easily overwashed. Determination as to whether armoring was easily overwashed was subjective and was determined by the USGS. Not accounting for these bluff protection structures in the city likely overestimates bluff erosion hazards in certain areas. CoSMoS 3.0 bluff erosion data includes uncertainty bands and, therefore, bluff hazards described in this vulnerability assessment could under- or over-estimate impacts. 3.5.3. Shoreline Erosion (Inundation Hazard Zone) The shoreline model includes a variable for long-term beach accretion or erosion based on an analysis of historical shoreline change. This variable represents sediment contributions from beach nourishment, bluff erosion and fluvial (river) contributions and was calculated through analysis of historical shoreline change dataset from 1970s to present. Based on coordination with the USGS, the long-term shoreline change variable included in the shoreline model for the city is 0.5 ft of shoreline gain per year on average. Historical averages of beach or bluff erosion does not account for accelerated erosion due to sea level rise. Fluvial conditions may also differ from historical norms as a result of climate change. Past rates of beach nourishment may not accurately represent beach management practices in the future. Beach nourishment rates and volumes have been decreasing over time in many areas in southern California because of funding and regulatory constraints for these types of projects. The shoreline model included coastal structures (rip rap, revetments and seawalls) and coastal infrastructure. Thus, shoreline erosion model results become invalid as the beach becomes fully eroded and possibly undermines coastal structures and infrastructure. Therefore, shoreline erosion is understated where the projected shoreline encounters a coastal structure or infrastructure. 3.5.4. Coastal Flooding (Flood Hazard Zone - Shoreline) Coastal flooding results were de-coupled with future shoreline position data. Thus, the coastal flooding results shown are based on today’s shoreline position instead of an eroded, future condition. This likely understates the flooding results and was recognized as a limitation in the preliminary data release. The future coastal flooding data will utilize the future shoreline position to then generate coastal flooding limits. Flooding limits are anticipated to be greater and extend more landward with the coupling of these analyses in the future release. Oct. 12, 2021 Item #7 Page 399 of 428 Sea Level Rise Vulnerability Assessment December 2017 A-13 The landward extent of coastal flood limits was based on the USGS, bare-earth DEM. Topographic features captured in this DEM effected the landward propagation of flooding. Coastal structures were implicitly captured in these results when these structures were large enough (revetments in the Village Planning Area). Small scale features, such as seawalls along Carlsbad Boulevard in the Tamarack Planning Area, were not captured in the DEM. Thus, coastal flooding limits are likely overstated in areas where small scale coastal structures were excluded from the modeling domain. 3.5.5. Lagoon Inundation (Inundation Hazard Zone) Areas in the lagoons subject to future daily tides were mapped using a DEM provided by city GIS staff. A mean higher high water vertical elevation of 5.3 feet (MLLW) was used to represent future, daily-high still water tidal elevations in the lagoons. The mean higher high water elevation was added to the projected sea level rise for each planning year (i.e., 2050 and 2100). Since the weir at Buena Vista Lagoon has a crest elevation of 7.89 feet (MLLW), it was found that this lagoon would only experience tidal inundation during the 2.0 m, year 2100 scenario. 3.5.6. Lagoon Flooding (Flood Hazard Zone - Lagoons) Moffatt & Nichol conducted a review of the CoSMoS model outputs with existing fluvial (river) models of the three lagoons in the city. Existing fluvial models of these lagoons were performed in connection with the North Coast Corridor project being led by SANDAG. Based on this review, Moffatt & Nichol found the following deficiencies in the CoSMoS 3.0 lagoon flooding model outputs: ❖ Coastal lagoons are included in the Tier II high resolution CoSMoS models; however, the lagoon bathymetry is derived from topo LIDAR. Thus, the lagoon area below the water surface is a simple flat surface that may not correctly represent the effects of tides and storms within the lagoon, this can lead to both under estimation and over estimation of hazards. ❖ CoSMoS is intended to model the 100-year storm from ocean conditions. The hydrograph (graphical representation of storm flow) is idealized and the peak flow included in the model is based on atmospheric pressure conditions that are produced during the coastal storms. The peak flow rate of the CoSMoS storm is about 10% of the FEMA 100-year fluvial discharge. The small storm used in the CoSMoS model underestimates the hazards that could exist during a 100-year fluvial storm with sea level rise conditions. ❖ Culverts or other manmade and natural underground pathways between coastal waters and land are not considered. This likely underestimates flooding hazards that may occur in areas connected to coastal waters by culverts and other manmade and natural conduits. Based on these deficiencies, Moffatt & Nichol developed a new data layer showing the limits of these lagoon flood hazards. Inundation hazard zones (areas subject to daily tides) were also mapped to show the migration of the lagoon shoreline landward. More detailed assessment of each of the findings per lagoon is provided in this section. Oct. 12, 2021 Item #7 Page 400 of 428 Sea Level Rise Vulnerability Assessment December 2017 A-14 3.5.6.1. BATIQUITOS LAGOON At Batiquitos Lagoon, CoSMoS results provide an adequate prediction scenario for a 100-year coastal storm and should be used for the nearshore area outside of the lagoon. The impacts of a 100-year fluvial storm are not included in the CoSMoS model, the small fluvial storm used in CoSMoS does not represent the effects of a 100-year fluvial storm in the lagoon during sea level rise conditions. The Moffatt & Nichol RMA-2 model results provide an adequate prediction scenario for the 100-year fluvial storm with sea level rise and should be used in the lagoon area for planning purposes. Batiquitos Lagoon and referenced basins are shown in Figure 7. A comparison of water surface elevations for the models reviewed are summarized in Table 4.

AGUA HEDIONDA LAGOON At Agua Hedionda, CoSMoS results provide an adequate prediction scenario for a 100-year coastal storm and should be used for the nearshore coastal area outside of the lagoon. The impacts of a 100-year fluvial storm are not included in the CoSMoS model, the small fluvial storm used in CoSMoS does not represent the effects of a 100-year fluvial storm in the lagoon during sea level rise condition. The Chang Hydraulic and Scour Studies for Proposed Interstate 5 Bridge Widening across Three Lagoons HEC-RAS model results adjusted by Moffatt & Nichol to account for sea level rise conditions under the 100-year fluvial storm provide a conservative prediction scenario and should be used in the lagoon area for planning purposes, additional fluvial modeling study is recommended if accurate results similar to that for Batiquitos Lagoon are desired. A comparison of model water surface elevations is shown in Table 5. Agua Hedionda Lagoon and referenced basins are shown in Figure 8.

BUENA VISTA LAGOON CoSMoS results provide an adequate prediction scenario for a 100-year coastal storm and should be used for the nearshore area outside of the lagoon. The impacts of a 100-year fluvial storm are not included in the CoSMoS model, the small fluvial storm used in CoSMoS does not represent the effects of a 100-year fluvial storm in the lagoon during sea level rise conditions. The two-dimensional Everest model results for current lagoon conditions from the Buena Vista Lagoon Enhancement Project DEIR provide an adequate prediction of water surface elevations for current sea level conditions with a 100-year fluvial storm and estimates for sea level rise conditions under the 100-year fluvial storm, these results should be used in the lagoon area for planning purposes.

Culverts and Storm Drain Systems The CoSMoS model currently does not include culverts, storm drain systems or other manmade and natural underground pathways between coastal waters and land. Thus, flooding limits may be understated in some areas. Increased water levels due to sea level rise, fluvial storms, coastal storms, high tides, and wave run-up can back into these conduits and result in flooding of upland areas into which these conduits drain. The potential for flooding of drainage areas connected to these systems is dependent on topography, conveyance invert elevations, slopes, backwater conditions, drainage structures, and other hydraulic factors. Increased tail water levels at the outlet of storm drain systems may cause flooding of low lying areas connected to these systems and flooding due to reduced drainage capacity of the system. Culverts intended to provide drainage during storm events could cause backwater flooding if the tail water levels are higher than the invert of the these structures. Culverts and storm drain systems that outlet into coastal lagoons or beach areas that could have potential backwater flow problems were identified using the city’s storm drain GIS database. Note that backwater flooding should not be expected for storm drains having functional flapgates. This data was not available at the time of this study. Storm water vulnerabilities as a result of tail water from future rates of sea level rise are summarized in Oct. 12, 2021 Item #7 Page 404 of 428 Sea Level Rise Vulnerability Assessment December 2017 A-18 Table 7 through Table 11. Culverts and storm drain systems could result in additional flooding not predicted by the CoSMoS model and additional study is recommended to validate the vulnerability of these storm drains.

Since the outcome of the relocation effort may affect the ultimate land uses on the current SDG&E service center site, staff recommends that the city exclude the LCP land use and zoning map changes, as recommended by the Planning Commission, from the LCP update. The graphics below compare the map revisions recommended by the Planning Commission (Graphic 1a and 1b) to the staff proposed revision on the SDG&E service center site (Graphic 2a and 2b).

Sea level rise impacts are discussed further in Chapter 7, Coastal Hazards. •Add the following policy after draft policy LCP-3-P.13: –Consider, as part of the evaluation of realigning the southern lanes of Carlsbad Boulevard inland, opportunities to create additional recreation areas (e.g., parks and other recreation facilities and amenities), and for the state campground to expand or retreat inland. Planning Area F Policy Planning Area F carries a Non-Residential Reserve (NRR) General Plan designation. Planning Area F is an “unplanned” area, for which land uses will be determined at a later date when more specific planning is carried out for areas west of the railroad right-of-way. A future Major Master Plan Amendment will be required prior to further development approvals for Planning Area F, and shall include an LCP Amendment with associated environmental review, if determined necessary. The intent of the NRR designation is not to limit the range of potential future uses entirely to non-residential, however, since the City's current general plan does not contain an “unplanned” designation, NRR was determined to be appropriate at this time. In the future, if the Local Coastal Program Amendment has not been processed, and the City develops an “unplanned” General Plan designation, then this site would likely be redesignated as “unplanned.” Future uses could include, but are not limited to: commercial, residential, office, and other uses, subject to future review and approval. As part of any future planning effort, the City and Developer must consider and document the need for the provision of lower cost visitor accommodations or recreational facilities (i.e. public park) on the west side of the railroad. {city of Carlsbad Property Days Inn Carlsbad Scandia Motel Motel 6 Carlsbad East Motel 6 Carlsbad South Ramada Carlsbad La Qu inta Inns & Suit es Carlsbad Legoland A rea Best Western Plus Beach View Lodge Canlsbad by the Sea Resort Holiday Inn Express & Suites Carlsbad Beach Carlsbad Inn Beach Resort Westin Carlsbad Resort & Spa Sheraton Hotel Carlsbad Resort & Spa West Inn & Suites @ Carlsbad Cape Rey Carlsbad, a Hilton Resort Legoland Castle Hotel Grand Pacific Palisades Resort Hyatt House San Diego Carlsbad Hilton Garden Inn Carlsbad Beach Ocean Palms Beach Resort Tamarack Beach Resort Legoland California Resort Hotel Beach Terrace In n Four Seasons Residence Club Aviara Park Hyatt Aviara Resort Total Hotel Rooms South Carlsbad State Beach Cam pground I Total Accommodations Source: Smith Travel Research, October 2018 Smith Travel Research Cost Scale Economy Economy Economy Economy Midscale Midscale Upper Midscale Upper Midscale Upper Midscale Upper Upscale Upper Upscale Upper Upscale Upper Upscale Upper Upscale Upscale Upscale Upscale Upscale Upscale Luxury Luxury Luxury Luxury Luxury Lower-Cost (per the average daily rate for "Economy" hotels) Rooms 45 20 140 162 121 110 41 '145 120 62 208 169 86 215 250 90 98 161 56 23 250 48 42 327 2,989 222 3,211 I {city of Carlsbad LEGEND Coastal Zone ~ City Limtt m Lagoon -+-Railroad ~ Coo.sral Viewshed D Paroel Subject lo Poli r;y LCP-5-P31 -Paroel Subject lo Policy LCP-5-P.32 Scenic Viewing Areas -Existing Public Trail - -Future Public Trail -Public Par11/Gathering Site -Public street/Freeway F IGURE 5-3B COASTAL V I EWS HE DS AND V IE W I NG AREAS {city of Carlsbad Visitor Commercial (VC) Visitor Commercia (VC)i ·h ~ ~ de, Jg -· r on ~, mte .ded to p. ovid.e ,, "tes · o co · e c · al use . th· 1t serve, ·the, · · a ·et ret· · s opp, · g~ enre -talll . entl . .nd r,ec e,af on .eeds of -r", "to ~ tou ·1 its,. and ·es ~ de t . {city of Carlsbad
