Location: 676 Moss Street (APN 618-010-31) Environmental Notice: The Director of Development Services has reviewed the Tentative Map extension for compliance with the California Environmental Quality Act (“CEQA”) and has determined that Tentative Map PCS18-0006 was adequately covered and addressed, consistent with CEQA Guidelines section 15162, in previously adopted 2020 Mitigated Negative Declaration (IS18-0004; SCH #2020049053). Recommended Action Adopt a Resolution approving the requested two-year time extension to Tentative Map PCS18-0006. SUMMARY Pursuant to Chula Vista Municipal Code (“CVMC”) Section 18.12.190, Shopoff Realty Investments (“Applicant”), on behalf of SLF-Moss Street, LLC (“Owner”), is requesting a time extension of approved Tentative Subdivision Map PCS18-0006 for an additional two years commencing from December 8, 2023 and expiring December 8, 2025 (“Project”). HOUSING IMPACT STATEMENT The action of extending the Tentative Map will not result in the construction of any housing units. However, 141 for-sale, multi-family residential units will be added to the City when the Final Map is recorded, and development occurs consistent with applicable general and specific plans as specified in Government Code Section 65451. ENVIRONMENTAL REVIEW The Director of Development Services has reviewed the proposed activity for compliance with CEQA and has determined that the Tentative Map was adequately covered in previously adopted Mitigated Negative Declaration and Mitigation Monitoring & Reporting Program (IS18-0004; SCH #2020049053). Therefore, no further environmental review is required. Page 5 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda P a g e | 2 DISCUSSION On December 8, 2020, the City Council approved the construction of 141 for-sale, multi-family residential units on an approximately 6.94-acre site located at 676 Moss Street. As part of that action, the City Council approved a Design Review permit (DR18-0028), a Variance (ZAV18-0001), and a Tentative Map (PCS18- 0006; Resolution No. 2020-281); the entitlements and the Tentative Map were originally due to expire on December 8, 2023 Since receiving City Council approval in 2020, the Owner has worked diligently to process the various grading and improvement plans for the project. However, additional time is needed to complete the Tentative Map’s conditions of approval Granting a two-year extension would assist the Owner and support the construction of additional housing within the City. On September 21, 2023, the Owner submitted an extension request pursuant to CVMC Sections 19.14.260, 19.14.600, and 18.12.190, to extend the expiration of the entitlements and the Tentative Map for an additional two years commencing from December 8, 2023, and expiring on December 8, 2025. Pursuant to CVMC 19.14.260(E) and 19.14.600(E), the Director of Development Services has found the proposed action to be in substantial conformance with the approved permit, and thus has extended the expiration date of the entitlements to December 8, 2025. However, CVMC 18.12.190 requires action from the Planning Commission to extend a Tentative Map, with the procedure found in the Subdivision Map Act, specifically, in Government Code section 66452.6. Although the extension request was submitted to the City prior to the expiration dates of the permits and the map, which would normally initiate an automatic extension of the Tentative Map until the extension request is scheduled and brought before the Planning Commission for decision, subsection (e) of Government Code section 66452.6 provides that the extension only lasts for 60 days, “or until the application for the extension is approved, conditionally approved, or denied, whichever occurs first.” The 60th day following December 8, 2023, was February 6, 2024. The Planning Commission did not meet for the first three regular meetings following the application for extension and was unable to act on the application prior to February 6th, with no fault on the part of the Owner. It is therefore recommended that to avoid the inequitable, unjust, and unreasonable effect of the strict application of Government Code section 66452.6 on the Owner’s request, the application of the deadline in that section of the Subdivision Map Act should be waived by the Planning Commission. The Tentative Map remains consistent with the City’s General Plan, Zoning Ordinance, and all policies and standards that were in place at the time of the Tentative Map’s original approval. There have been no changes to the Tentative Map. CONCLUSION The Director of Development Services has determined that a noticed public hearing is not required since there have been no changes to the Tentative Subdivision Map. Therefore, Staff recommends that the Planning Commission approve the requested map extension. Page 6 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda P a g e | 3 DECISION-MAKER CONFLICT Staff has reviewed the property holdings of the Planning Commission members and has found no property holdings within 1,000 feet of the boundaries of the property which is the subject of this action. Consequently, this item does not present a disqualifying real property-related financial conflict of interest under California Code of Regulations Title 2, section 18702.2(a)(7) or (8), for purposes of the Political Reform Act (Cal. Gov’t Code §87100, et seq.). Staff is not independently aware and has not been informed by any Planning Commission member, of any other fact that may constitute a basis for a decision-maker conflict of interest in this matter. FISCAL IMPACT There are no current year or ongoing fiscal impacts to the General Fund or Development Servic es Fund as a result of this action. All costs incurred by processing this application are borne by the applicant. ATTACHMENTS 1. Location Map 2. Planning Commission Resolution 3.

Thus, no further environmental review is required. NOW THEREFORE BE IT RESOLVED that the Planning Commission hereby (1) finds that waiver of the strict application of California Government Code section 66452.6 (e) to the Page 9 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda PC Resolution No. 2024-04 Date 03/27/2024 Page 2 Tentative Map is approved to prevent an unwarranted hardship on the Owner, and (2) adopts the Resolution approving the Tentative Map time extension.

Location: 795 H Street (APN: 571-330-35) Environmental Notice: The proposed project qualifies for a Class 11 categorical exemption pursuant to Section 15311 (Accessory Structures) of the California Environmental Quality Act (“CEQA”) Guidelines. Recommended Action Adopt a resolution approving Planned Sign Program No. PSP23-0002 and issue a Coastal Development Permit for its implementation based on the findings and subject to the conditions contained therein. SUMMARY PSIP Wohl Bay Boulevard, LLC (“Applicant”) requests approval of a Planned Sign Program (“PSP”) consisting of tenant wall signs, building address wall signs, and a project identification monument sign (“Project”). The proposed Project is located on an 8.72-acre site at the northwest corner of H Street and Bay Boulevard (“Project Site”). HOUSING IMPACT STATEMENT The Project Site is located within the General Industrial (IG) zone of the Bayfront Specific Plan, which does not permit residential uses. No housing is proposed as part of this Project. ENVIRONMENTAL REVIEW The Director of Development Services has reviewed the proposed Project for compliance with CEQA and determined that the Project qualifies for a Class 11 categorical exemption pursuant to Section 15311 (Accessory Structures) of the CEQA Guidelines. Therefore, no further environmental review is required. DISCUSSION On May 3, 2023, the Applicant submitted a PSP application for the approval of five (5) signs to be located on an existing industrial site currently under redevelopment. Proposed signage includes two (2) tenant wall signs, two (2) building address wall signs, and one (1) project identification sign. The Project Site is located within the Bayfront Specific Plan, which governs and regulates land uses and development in the Chula Vista Page 21 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda P a g e | 2 coastal zone through the implementation of its Land Use Plan. The Bayfront Sign Program, an appendix to the Bayfront Specific Plan, authorizes the Planning Commission to make decisions regarding appropriateness of private signs, preserving the integrity of the Bayfront and encouraging creative sign design. All signs within the Bayfront Specific Plan are subject to the regulations in the Chula Vista Municipal Code (“CVMC”) and the specific plan unless modified by the provisions in the Bayfront Sign Program or a separate sign program approved by the Planning Commission. The Bayfront Sign Program includes a phasing plan to address changing business needs in different stages of Bayfront development. The interim phase includes the early period of Bayfront redevelopment; during this phase, sign regulations are more relaxed. However, when the Bayfront is sufficiently developed, the need for abundant signage will decrease because the Bayfront will have been established and can attract business traffic on its own. In the interim phase, the Bayfront Sign Program limits commercial uses adjacent to the freeway to two wall signs or one ground sign, with a total allowable sign area of 100 square feet. These signs are required to be removed by a specific date, at which time they must comply with final phase sign regulations. In the final phase, the Project Site will be limited to 50 square feet of total sign area, which can be split between the two street frontages. While the Bayfront Sign Program does not contain specific dates indicating when the interim phase begins or ends, Staff has concluded that the Bayfront Master Plan is in the early phases of development; therefore, the proposed Project falls within the interim phase of the Bayfront’s overall development schedule. Wall Signs The proposed sign program includes two 50-square foot tenant wall signs mounted on the existing building facade; one sign faces southward to H Street, and the other faces eastward to Bay Boulevard. The proposed wall signs comply with the maximum sign area allowed for commercial developments in the interim phase of the Bayfront Sign Program and are compatible with and proportionate to the architecture of the existing building. Project Identification Sign The proposed Project includes one project identification sign along H Street with a sign area of 40 square feet and a height of five (5) feet. Because the Bayfront Specific Plan limits the site to either two wall signs or one ground sign in the interim phase, this sign is a proposed deviation from the established standards. However, the proposed dimensions of the sign would otherwise comply with the standards outlined in the Bayfront Sign Program. The Planning Commission is authorized to allow an individual project to deviate from established standards if it believes the character of the Bayfront will be enhanced by its action. (CVMC Chapter 19.85, Appendix B – DESIGN REVIEW; Submittal and Review Procedures, par. 4.) (“Appendix B”) A proposed Project identification sign, displaying the name “Gateway at the Bay,” will be located at the driveway to the existing building located at 795 H Street. The sign aims to memorialize the history of the industrial era of Rohr Industries and combine it with a modern waterfront theme. Corten steel will form the vertical batten backdrop and provide support for the wave pattern. A natural color palette and a weather- resistant steel offering an age-old rustic look create a graphic identification that is consistent with the Bayfront theme and architecturally compatible with the existing building. Page 22 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda P a g e | 3 CONCLUSION Staff recommends that the Planning Commission approve the proposed Planned Sign Program, subject to the conditions contained in the resolution. The proposed Planned Sign Program generally complies with the applicable policies, guidelines, and design standards of the Bayfront Specific Plan and the CVMC. Where the Applicant proposes an additional project identification sign, Appendix B provides that the Planning Commission may allow deviations from the established guidelines to enhance the character of the Bayfront. Staff supports the Applicant’s request for the additional project identification sign. DECISION-MAKER CONFLICT Staff has reviewed the property holdings of the Planning Commission members and has found no property holdings within 1,000 feet of the boundaries of the subject property. Consequently, this item does not present a disqualifying real property-related financial conflict of interest under California Code of Regulations Title 2, section 18702.2(a)(7) or (8), for purposes of the Political Reform Act (Cal. Gov’t Code §87100, et seq.). Staff is not independently aware and has not been informed by any Planning Commission member of any other fact that may constitute a basis for a decision-maker conflict of interest in this matter. FISCAL IMPACT There are no current year or ongoing fiscal impacts to the General Fund or Development Services Fund resulting from this action. All costs incurred processing this application are borne by the Applicant. ATTACHMENTS 1. Location Map 2. Planned Sign Program PSP23-0002 3. Planning Commission Resolution 4.

The proposed Project, as conditioned, will enhance the character of the Bayfront and assist in creating a distinctive atmosphere for it. Page 24 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda PC Resolution March 27, 2024 Page 2 The intent of the Bayfront Specific Plan sign program is to establish a format for imaginative sign design appropriate for the Bayfront. The Bayfront Sign Program includes a phasing plan to address changing business needs in different stages of Bayfront development. The interim phase includes the early period of Bayfront redevelopment; during this phase, sign regulations are more relaxed. However, when the Bayfront is sufficiently developed, the need for abundant signage will decrease because the Bayfront will have been established and can attract business traffic on its own. Because business needs will change as the Bayfront develops, signage may be allowed more liberally in the interim stage of Bayfront’s development. The sign program (Chula Vista Municipal Code Chapter 19.85, Appendix B) also authorizes this commission to allow an individual project to deviate from established guidelines if the character of the Bayfront will be enhanced by its action. While the sign program would limit the proposed Project to two wall signs or one ground sign only, allowing both wall and ground signs will draw attention to the Bayfront from passersby along the adjacent Interstate 5 as well as from those within the Bayfront area itself. As one of the first redevelopments within the specific plan area, given its proximity to the specific plan area boundary, the proposed Project should be seen as the first step in attracting ground-level business activity to the Bayfront, and applies during the interim stage of the development of the Bayfront. Additional signage will signify to the greater community that the Bayfront is open to and for businesses. The proposed signs are generally consistent with the design guidelines and standards established by the Bayfront Specific Plan and the Chula Vista Municipal Code (“CVMC”) as they relate to size, height, illumination, spacing, orientation, and/or other non- communicative aspects of signs. The proposed gateway sign is, by necessity, much larger than the 50-square foot maximum sign area because it will serve as a primary identifier for the Project. The sign maintains a sense of scale relative to the Bayfront’s generally flat topography and will be integrated with the surrounding environment, featuring lighting that will be harmonious with the existing building’s architecture. 2. The proposed Project, as conditioned, is consistent with the design guidelines approved for the Chula Vista Bayfront Specific Plan. The proposed sign colors and materials create a graphic identification that is consistent and architecturally compatible with the existing industrial building. Because the Project is still subject to the dictates of the Chula Vista Local Coastal Program, the Project must be in accordance with the design guidelines of the Bayfront Specific Plan. This sign program’s design is symbolic to the business and represents both the Chula Vista Bayfront history and the working waterfront of industries and businesses dedicated to trade, recreation, commerce, and tourism along the San Diego Bay. BE IT FURTHER RESOLVED that the Planning Commission, based on the findings above, does hereby approve Planned Sign Program PSP23-0002 and issues a Coastal Development Permit for implementation of said program, subject to the following conditions: Page 25 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda PC Resolution March 27, 2024 Page 3 I.

GOAL AND OBJECTIVES Goal The goal of the Chula Vista Bayfront Sign Program is to control signs – eliminating those which are obtrusive and encouraging those that are creative and interesting while establishing a sense of place for the area. Objectives 1. To establish guidelines and criteria for all signs within the Chula Vista Bayfront Redevelopment Project area. 2. To establish a Planning Commission charged with the following tasks: (a) to make decisions regarding appropriateness of private signs; (b) to preserve the integrity of the Bayfront; and (c) to encourage creative sign design. 3. To encourage vitality within a development through the use of sign design. 4. To avoid the proliferation of private business signs along the freeway. 5. To incorporate into the design of public signs the elements of the bayfront logo. 6. To promote bayfront development progress, special events, and to identify, discreetly but effectively, new businesses coming into the area. 7. To assure equality in sign impact. 8. To establish “Bayfront” identity through a cooperative program with Caltrans. DESIGN REVIEW The City of Chula Vista’s Planning Commission shall review all parts of the bayfront project – the architecture, landscaping proposals, and each sign proposed for the area. This mechanism will ensure the regulation and control needed to create a distinctive atmosphere for the bayfront. Chula Vista Planning Commission – Appointed The Chula Vista Planning Commission has been appointed to function as the Planning Commission herein described and has been charged with the responsibility of interpreting and applying sign design guidelines contained in this document. The board is specically directed to encourage creative sign design and diversity. The City Council shall retain ultimate authority for fair and equitable application. Submittal and Review Procedures Submittal of a complete program of all desired signs shall be required for every development proposed within the bayfront. Sign plans should be submitted coincidentally with development plans scheduled for architectural review. The minimum submittal shall include a plot plan with property lines, building footprints, curb and center lines of adjacent streets, building and sign elevations, and location of each proposed sign. Each sign will be drawn to scale indicating colors, materials, typestyles, dimensions of lettering, copy areas, sign height and width, methods and intensity of lighting, and means of installation. The Planning Commission has established its own requirements and procedures for submittals and has the discretion to change these from time to time as it deems necessary. The Planning Commission also has the authority to allow an individual project to deviate from established guidelines if the character of the bayfront will be enhanced by its action. GUIDELINES: IN GENERAL Design Intent and Rationale This sign program strives to ensure that graphics in general, and each sign in particular, becomes a viable, integral part of the concept of Chula Vista bayfront redevelopment. The intent of this program is to establish a format for imaginative sign design which is appropriate for the bayfront. Every effort must be made to create graphic identications that are integral and consistent with the bayfront theme and with the architecture of each particular project. Graphic identications which are symbolic of the business or service rather than standard “letter copy” are encouraged, i.e., logo. The design of signing for a project within this area should consider using pictorial imagery in combination with well-considered typefaces, spacing, colors,and material. (Refer to Exhibit Two for rule of good sign design.) Two-Phase Program Because the needs of businesses in the bayfront will be different in its early stages and in the nal development, guidelines have been adopted to accommodate their needs during both these phases. During the interim phase (early in bayfront development), developments will receive liberal signing. Once the bayfront is sufciently developed, the need for abundant signing will be lessened because the bayfront’s identity will be established and will help to attract business trafc. A more “low-key” sign program has been adopted for the nal development phase. The Inuence of Bayfront Topography The general topography of the bayfront is at and open. The natural color of the area is muted. Therefore, signing must be discreet in order to avoid an overwhelming impact. A. Low-Key Sign Program These guidelines establish a sign program which is “low-key.” Signs are intended to be adequate for identication, but not for advertising. Harmony of materials, textures, forms, colors, scale, and feeling is intended for the Chula Vista Bayfront Redevelopment Project. The Necessity for Size Regulation Uniform sign parameters are created to ease competition among private interests. This assures more equal distribution of the right to identify a place of activity. 11.08.2023795 H STREET CHULA VISTA, CA SDG20-0037-00 3 PAGE BAYFRONT SIGN PROGRAM & CHULA VISTA SIGN CODEThis conceptual design is based upon a preliminary review of entitlement requirements and on unverified and possibly incomplete site and/or building information, and is intended merely to assist in exploring how the project might be developed. Signage shown is for illustrative purposes only and does not necessarily reflect municipal code compliance.Page 34 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Height Limitation The eight-foot height limitation proposed in this criteria is in accordance with the intent of the California Coastal Commission’s guidelines, and also maintains a sense of scale to bayfront topography and the intent of achieving a “low-key” sign program. Roof Signs Signs mounted on the roofs or mechanical penthouses of any building are prohibited. Such signs violate the intended bayfront scale and are not in keeping with a distinctive bayfront sign program. Ground Signs Encouraged Low ground signs are encouraged. They should be integrated with the landscape, complementary to the architecture, incorporated into retaining walls or other landscape features. The objective is to reduce visual clutter. Wall Signs Wall signs must be compatible with and proportionate to the architecture, and maintain harmony of materials and form. The purpose of these signs is to identify the business or private development; whole wall areas are not intended to be “read” as sign structures or sign backgrounds. Only one wall sign shall be visible at one time. Support Structure Support structures should be integral parts of entire sign design and have aesthetic as well as structural importance. Lighting Lighting methods should be considered a part of each sign. The intensity and color of light should be harmonious with the building architecture and sign design. In any lighted sign, the intensity should be no more than that required for nighttime reading, ashing/strobe light shall not be used. Signs must be modied after installation if lighting proves too intense. Guideline Jurisdiction The guidelines specied herein shall govern signs within the Chula Vista Bayfront Redevelopment Project. Since every possibility cannot be anticipated by this report, details which might be omitted shall be governed by the Chula Vista Zoning Ordinance. Where there is a conict between the Bayfront Redevelopment Sign Program and the Chula Vista Zoning Ordinance, the more restrictive regulation shall govern. Restrictions and Prohibited Signs The following signs shall be prohibited or restricted as noted: a. Pole signs. b. Flashing, oscillating, animated or moving signs, or signs with moving parts shall be prohibited. c. The use of uorescent-type paints is prohibited. d. Signs advertising goods shall be prohibited. e. All billboard signs shall be prohibited. f. Temporary signs, banners, sale notices, etc., shall be displayed behind the glass of the structure. The Planning Commission shall establish requirements and procedures for submittals. New Signs The sign owner shall be responsible for the fulllment of all requirements of these criteria. Conformance will be strictly enforced and nonconforming or unapproved signs or any part thereof shall be brought into conformance at the expense of the owner. Existing Signs Existing (nonconforming) signs shall be brought into conformance either: (1) when any change of land use occurs, or (2) by the nal development phase, or whichever occurs rst. Approvals for signs and their installation shall be obtained by the owner or his representative prior to installation. All signs shall be constructed, installed, and maintained in as-new condition at the owner’s expense. All current building and electrical codes shall govern the construction of signs. GUIDELINES: SPECIFIC Public Signs Public signs are those built and maintained by the city or other public agency through an adopted nancial plan. They are divided into subsections according to function and location. Private Signs Guidelines for private signs are organized according to location and project type. A somewhat more liberal criteria is established to serve business needs during the bayfront’s initial development phase. The signs approved in this phase are called “interim signs.” When the bayfront is substantially built out, interim signs must be replaced, modied, or removed entirely to comply with the more restrictive sign criteria established for the nal development phase. The redevelopment agency shall determine when this changeover will occur based on their appraisal of the bayfront’s progress. Developers submitting signs for approval for projects to be built close to the changeover date will be given the notice of complying with the nal- City of Chula Vista September 2012 Bayfront Specic Plan Amended on October 16, 2018 67 phase criteria or building interim signs which would be removed or modied at their expense in the near future. The rationale for this phased system is that when the bayfront development is beginning and a bayfront identity is being established, certain private projects will need additional signs to attract business. When the area nears completion and a bayfront identity is clearly established, the bayfront itself will attract business trafc. At this time, more restrictive sign criteria can be implemented. FINAL PHASE: ULTIMATE BAYFRONT DEVELOPMENT STATE Freeway Signs: Private signs which are oriented to the freeway shall not be allowed, except as provided during the interim phase. Corner Lots: The identication allowance for sign development on corner lots may be divided to provide for a sign on each frontage; however, the total allowance for both signs combined is not to exceed 50 square feet. Multi-tenant Buildings or Complexes: Ofce, retail-commercial, and industrial uses which are multi-tenant shall be allowed additional tenant identication signs: each tenant shall be allowed a maximum of three square feet on or adjacent to the entry door. These tenants signs shall be visible from on-site parking and/or pedestrian walkways, but not intended to be readable from public streets. Directional and Information Signs: These signs shall be allowed on a need basis. They shall be directional in nature and not intended as identication signs. Their maximum height shall be four feet with four square feet maximum copy area per side. Special Event Signs (Temporary): Special events such as grand openings shall be allowed temporary signs. Such signs shall have a limited life as determined by the Planning Commission. Construction Signs (Temporary): Signs for owners, contractors and subcontractors, architects, etc. for new projects under construction shall be subject to Planning Commission approval. Allowable Copy Area 1. Industrial and Ofce Uses: Industrial and ofce uses shall be allowed one identication sign per lot, visible from the internal street. Signs shall not exceed 40 square feet in height. Total sign area may include a directory or tenant listing if the project is multitenant. INTERIM PHASE: BAYFRONT DEVELOPMENT STAGE 1. Commercial Uses Adjacent to Freeway: Commercial businesses will require some identication from the freeway during the bayfront development period. Such uses with freeway exposure shall be allowed either wall or low-prole monument signs with name and/or logo Only during the bayfront development phase, and such signs shall have a specic date by which they must be removed. If the business logo is wellestablished as an identity mark, then use of logo alone is preferable. Each lot may have two wall signs or one ground sign only. No pole signs or roof signs are permitted. One wall sign shall be visible at a time. Maximum total copy area shall be 100 square feet. Ground signs may be double-faced or parallel to the roadway and are intended to be low-prole monument signs. 11.08.2023795 H STREET CHULA VISTA, CA SDG20-0037-00 4 PAGE BAYFRONT SIGN PROGRAM & CHULA VISTA SIGN CODEThis conceptual design is based upon a preliminary review of entitlement requirements and on unverified and possibly incomplete site and/or building information, and is intended merely to assist in exploring how the project might be developed.

Page 50 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda P a g e | 1 March 27, 2024 ITEM TITLE Amendments to the City of Chula Vista General Plan to Establish a Safety Element by Consolidating and Updating Safety Goals and Policies in Compliance with State Law. Location: Citywide Environmental Notice: Pursuant to State California Environmental Quality Act (“CEQA”) Guideline Section 15162, a subsequent Environmental Impact Report (“EIR”) or a Negative Declaration is not required for the update to the City’s Safety Element in that substantial changes are not proposed, the circumstances to which the General Plan was adopted have not changed, and no new information of substantial importance has arisen since the prior environmental documents have been certified. Furthermore, it has been determined that the proposed consolidation of safety goals and policies is exempt from the CEQA Guidelines pursuant to Sections 15060(c)(2) and 15061(b)(3) in that the proposed amendments which are primarily limited to policy modifications and updates in compliance with Government Code Section 65302(g)1 through 9 and are not anticipated to result in a direct or reasonably foreseeable indirect physical change in the environment, nor will the proposed changes have the potential for causing significant effect on the environment. Recommended Action To adopt a resolution recommending that the City Council establish a Safety Element within the General Plan in compliance with State Law SUMMARY Senate Bill 1035 (“SB 1035”) requires that a local jurisdiction update its Safety Element upon each revision of its Housing Element or Local Hazard Mitigation Plan. The City of Chula Vista updated its Housing Element in October 2022 and is now establishing a Safety Element in compliance with SB 1035. HOUSING IMPACT STATEMENT No housing units are proposed as part of this General Plan policy update. ENVIRONMENTAL REVIEW The Director of Development Services has reviewed the proposed Safety Element for compliance with the CEQA and determined that the Safety Element does not require a subsequent EIR or a Negative Declaration for the update to the City’s Safety Element in that substantial changes are not proposed, the circumstances to which the General Plan was adopted have not changed, and no new information of substantial importance Page 51 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda P a g e | 2 has arisen since the prior environmental documents have been certified. Furthermore, it has been determined that the proposed consolidation of safety goals and policies is exempt from the CEQA Guidelines pursuant to Sections 15060(c)(2) and 15061(b)(3) in that the proposed amendments which are primarily limited to policy modifications and updates in compliance with Government Code Section 65302(g)1 through 9 and are not anticipated to result in a direct or reasonably foreseeable indirect physical change in the environment, nor will the proposed changes have the potential for causing significant effect on the environment. Therefore, no further environmental review is required. BACKGROUND The City’s existing General Plan was approved in 2005 and included six elements: Land Use and Transportation; Economic Development; Housing; Public Facilities and Services; Environmental; and Growth Management. Goals and policies related to issues of safety were included within the Public Facilities and Services and Environmental Elements, which covered the following: Flooding and Erosion; Seismic and Geologic Instability; Wildfire; Climate Resiliency; Crime; Health Emergencies; and Hazardous Materials. This proposal would consolidate and update those goals and policies into a standalone Safety Element within the General Plan. In 2018, the Governor signed into law SB 1035. The law requires local jurisdictions to update their General Plan’s Safety Element upon each revision of the housing element, or local hazard mitigation plan, but not less than once every eight years. Each update is required to address new information relating to flood, fire hazards, climate adaptation and resiliency strategies applicable to the city or county that was not available during the previous version of the safety element. In addition to SB 1035, a number of other Assembly (AB) and Senate bills (SB) were approved that require amendments to the General Plan’s Safety Element as listed below: • Update flood-related information and strengthen flood protection measures (AB 162) • Local Hazard Mitigation Plan integration or incorporation by reference into the Safety Element (AB 2140) • Identification of evacuation routes and access to two or more evacuation routes for residential areas (SB 1241) • Consultation with Cal FIRE and the Department of Conservation on wildfire policies (SB 1241) • Analysis of evacuation routes to include the safety, viability, and capacity under a range of emergency scenarios (AB 747 and SB 99) Additionally, if the Safety Element is approved before June 1, 2024, the City becomes eligible to qualify for the Fire Risk Reduction Community List (“FRRCL”). The Fire Risk Reduction Community List, as mandated by PRC 4290.1, is a list of local agencies located in a very high fire hazard severity zone that meet best practices for local fire planning. Should the City be added to this list, it would allow the Fire Department increased qualification for grant opportunities and allow Chula Vista residents to potentially qualify for reduced fire insurance rates, and/or fire insurance rates that would not escalate. Page 52 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda P a g e | 3 DISCUSSION Public Outreach An online survey was designed and posted on the City’s website to request input from community members identifying hazards and other locally relevant safety issues, such as emergency response times, pandemics, hazardous materials spills, crime reduction, etc. The survey was provided in English and Spanish and was open for 4 weeks, from August 10, 2023 to September 7, 2023. A total of 95 surveys were completed from residents, visitors and people who work within the City. Participants cited severe weather and extreme heat as the most prevalent issues experienced in the City. A summary the completed surveys is included as Attachment 1. In addition to the public survey, staff held two community meetings to solicit feedback, one in the eastern part of the City and one in the western part. The meeting in the eastern portion of the City took place on September 27, 2023 at Montevalle Community Center and was lightly attended. The meeting on the western portion of the City was held in City Council Chambers on September 28, 2023, and was attended by four community members. Attendees at both meetings viewed the exhibits and discussed their experience with flooding, power outages, fire, etc. with staff and the City’s consultants, Michael Baker International. Staff listened and took all the comments into consideration when drafting the Safety Element. The Draft Safety Element was made available online for public review from March 4, 2024 through March 19, 2024. Staff received one response regarding implementation of Safety Element Action Items and additional fire fighting equipment. SB 1241 requires consultation with Cal FIRE and the Department of Conservation on wildfire policies to be included in the Safety Element. Staff submitted the Draft Safety Element to Cal Fire for informal review on February 22, 2024, and received confirmation from Cal Fire that it meets their standards. As such, Staff has submitted the Draft Safety Element for consideration to the Department of Forestry which will be considered at their April 9, 2024 meeting. Results of this meeting on April 9, 2024 will be incorporated into this item when presented to the City Council. Proposed Amendments The proposed amendments would consolidate and update goals and policies from several elements of the General Plan into a new standalone Safety Element (Attachment 2). The amendment would include four new Goals and the Policies necessary to implement them: • Goal SE 1.0: Minimize the potential for loss of life, injury, damage to property, economic and social dislocation, and unusual public expense due to natural hazards. The policies to implement this goal include those related to Flooding and Erosion, Seismic and Geologic Instability and Wildfire. • Goal SE 2.0: Minimize the potential for loss of life, injury, damage to property, economic and social dislocation, and unusual public expense due to human-made hazards. Page 53 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda P a g e | 4 The policies to implement this goal include those related to Crime, Health Emergencies and Hazardous Materials. • Goal SE 3.0: Ensure residents are thoroughly informed about hazards and emergency preparedness programs and procedures. The policy to implement this goal relates to promoting public safety awareness. • Goal SE 4.0: Ensure the City is well-prepared for an effective emergency response. The policies to implement this goal include those ensuring City permitting and approval processes allow for emergency preparedness, ensure that emergency preparedness planning is done collaboratively on a regular basis and includes City residents and businesses as part of the program. In addition to the proposed amendments, an Evacuation Route Capacity and Viability Study was prepared to understand the evacuation impacts under two scenarios: fire and dam inundation in compliance with AB 747 and SB 99 (Attachment 3). This document does not become part of the General Plan but rather informs the public and First Responders, as well as ensuring evacuation impacts are minimized. CONCLUSION Staff recommends that the Planning Commission recommend adoption of the Safety Element to the City Council. DECISION-MAKER CONFLICT Staff has reviewed the decision contemplated by this action and has determined that it is not site-specific and consequently, the real property holdings of the Planning Commission members do not create a disqualifying real property- related financial conflict of interest under the California Political Reform Act (Cal. Gov’ t. Code § 87100, et seq.). Staff is not independently aware and has not been informed by any Planning Commission member, of any other fact that may constitute a basis for a decision-maker conflict of interest in this matter. FISCAL IMPACT There are no current or ongoing fiscal impacts to the General Fund or Development Services Fund as a result of this action.

Black, AICP, Director of Development Services Page 55 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Chula Vista Community Engagement The Chula Vista Safety Element Update included community outreach through a community-wide survey and two identical workshops- one in the east and one in the west of the City. Several key stakeholders were involved in the project, including the Coastal Commission, San Diego County, Cal Fire, and the local Police and Fire Departments. These stakeholders play a significant role in ensuring that the safety element aligns with regulation and current planning efforts and meets the requirements of emergency response agencies. Below is the summary of community engagement. Survey Results Michael Baker International prepared and posted an online survey to get input from community members to identify hazards and other locally relevant safety issues, such as emergency response, pandemics, hazardous materials spills, and crime reduction. The survey launched in English and Spanish and was open for 4 weeks, August 10 to September 7, 2023. City Affiliation A total of 95 completed surveys were received. Of these respondents, 55.3 percent live in the City of Chula Vista, 64.9 percent work in the City, and 8.5 percent visit the City, but live and work elsewhere, as indicated in Figure 1. About 25.5 percent of respondents both live and work in the City. Figure 1: City Affiliation Live in Chula Vista Work in Chula Vista Visit Chula Vista, but live and work elsewhere 0.00% 20.00% 40.00% 60.00% 80.00% Do you: (Select all that apply) Page 56 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Disasters or Hazards Experienced The participants were asked which types of disasters or hazards their household has experienced while residing in, working in, or visiting Chula Vista, As shown in Figure 2, severe weather and extreme heat were the most prevalent hazards experienced in the City. Pandemics or epidemics were also experienced at a high rate, which is likely due to the pandemic COVID-19 which was a global pandemic experienced just a few years before the survey and was not a hazard specific only to the region. Many respondents have experienced more than one of these hazards. Figure 2: Disasters or Hazards Experienced Page 57 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Concern for Hazards As shown in Figure 3, there is very little concern by survey respondents for tornadoes or dam failure. Concern for wildfires, climate change, and drought were the most prevalenet, which is consistent with the hazards that have primarily affected residents of Chula Vista in recent years. Figure 3: Concern for Hazards Concern for Evacuation Also in regards to community concenr for hazard or disaster, Figure 4 illustrates that concern for evacuation due to disaster is present, but not extreme. In the instance of an evacuation, 98 percent of respondents have transportation in order to evacuate. Page 58 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Figure 4: Concern for Evacuation Hazard Notification Almost 80 percent of survey respondents indicated that in the instance of emergency in the City of Chula Vista, they would expect to be notified via AlertSanDiego, which is a telephone notification system. Many respondents also indicated that they receive notifications via television, radio, or the SD Emergency App, which includes text notifications. Social media websites like NextDoor and Twitter are not commonly used for this purpose. Figure 5: Hazard Notification Not concerned Somewhat concerned Concerned Very concerned Extremely concerned 0.00% 10.00% 20.00% 30.00% How concerned are you about evacuating in the event of a disaster? Page 59 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Household Emergency Supply Preparedness As noted in Figure 6, 77.4 percent of respondents have done some emergency preparation, with 63.4 percent of survey respondents being somewhat prepared to get along without electricity, gas, or water for one to five days, and 14 percent being very prepared. 23 percent of respondents are not at all prepared with emergency supplies. Figure 6: Household Emergency Supply Preparedness Steps to Prepare for a Local Hazard Event The most common steps the community has taken to prepare their household for potential local hazard events are installing smoke detectors and storing first aid kits. Very few respondents have taken more intensive measures such as completing medical alert registration, anchoring furniture, or completing Community Emergency Response Team (CERT) training. Figure 7: Steps to Prepare for a Local Hazard Event Not at all prepared Somewhat prepared Very prepared 0.00% 20.00% 40.00% 60.00% 80.00% How prepared is your household to get along without electricity, drinking water, or natural gas supply for one to five days? Page 60 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda In addition to taking measures to prepare the household for local hazards, about 62 percent of respondents have some sort of hazard-specific insurance. Insurance types range from earthquake insurance, flood insurance, fire insurance, and more. Figure 8: Hazard Insurance Suggestion on Community Program Respondents also suggested awareness and preparedness programs that they think the City should provide to promote resident actions to reduce exposure to the risks associated with hazards. Some suggested that the educational aspects for hazard preparedness could be included in a booth by the City at public events. Many respondents expressed specific concerns with wildfire and fire safety and evacuation during hazard events. Respondents believe there may not be enough firefighters to combat a wildfire if a major issue should exist. Additionally, a concern was raised about the need to clear out the canyons in order to prevent wildfires. In addition to fire preparedness, respondents expressed that it could be beneficial for both the fire and police departments to be prepared for active shooter situations. Respondents suggested that there is a need for training for involvement in active shooter situations, as well as medical training to prepare for an active shooter situation. No Not sure Earthquake insurance Flood insurance Fire insurance (in addition to standard home insurance) Other insurance (please specify) 0.00% 5.00% 10.00% 15.00% 20.00% 25.00% 30.00% 35.00% 40.00% Do you have hazard-specific insurance? Select all that apply. Page 61 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Community Workshops Two identical in-person community outreach meetings were facilitated by the City to solicit in-person input and educate the public about the Safety Element update process. These are listed below. • Meeting 1: September 27, 2023, Montevalle Recreation Center • Meeting 2: September 28, 2023, City Council Chambers The City created and distributed flyers in English and Spanish (see Figure 9). These were distributed via social media and posted on the City website. Figure 9: Flyers in English and Spanish The workshop provided information on Safety elements, the reason for the update, and hazard maps including faults, shake potential, liquefaction, landslides, wildfire, flood map, Dam inundation, Sea Level rise, and Tsunami. An interactive exercise was also organized using sticker dots for the participants to select the hazards that concerned them the most. Participants were also asked to provide suggestions on preparedness programs that they thought would be beneficial to Chula Vista residents. A presentation was done at the beginning of the workshop to provide information regarding Safety elements. Four participants attended meeting 1 and Meeting 2 was attended by nine participants.

The Safety Element is a mandatory chapter of a jurisdiction's General Plan, as required by California Government Code Section 65302, and addresses the need to protect citizens from risks associated with natural and man-made hazards. Natural hazards constitute natural phenomena and include naturally occurring events like geologic and seismic activity, wildfire, flooding, and drought. Conversely, man-made hazards are hazardous events that are caused by human activity. Man-made hazards may include hazardous materials spills, terrorism, sabotage, crime, and human-caused health crises or fires. These hazards have the potential to cause serious impacts on the City of Chula Vista and its residents. The Safety Element contains goals, policies, and actions to reduce the potential short- and long-term risk of death, injuries, property damage, economic damage, and social dislocation associated with hazards. The City's response to these issues will determine its success in maintaining and attracting residents and businesses. Chula Vista will address safety issues comprehensively to ensure an enjoyable, safe, and healthy environment for Chula Vista's residents, workforce, and visitors. 1.1. Relationship to Other Documents The Safety Element works jointly with other General Plan elements and planning documents and is implemented by several City departments through goals, policies, and implementation methods. The City’s Safety Element relates to nearly every General Plan element but most closely relates to the Land Use, Transportation, Environmental1, and Housing Elements of the City’s General Plan. Additionally, the Safety Element relates to other planning documents, including the Chula Vista Emergency Operations Plan (EOP), Multi-Jurisdictional Hazard Mitigation Plan (MJHMP), and Climate Action Plan. These plans are integrated in the Safety Element. The Land Use and Transportation Element provides a central framework for the General Plan and serves as a compass to guide the public, planners, decision-makers, and City staff on the desired pattern of development in Chula Vista. Development is closely linked to safety as it provides an opportunity to design and guide the growth of the City with hazards and safety in mind. 1.1.1. City’s General Plan Elements The Land Use and Transportation Element establishes the land use designations, intensity of development, and nature of development. The element reflects anticipated levels of development including critical facilities such as schools, city services, utilities, police and fire protection services, and so on. It is necessary to make sure, as much as possible, that these developments are in areas that are not in hazard zones or that the hazards are mitigated to ensure the safety of the structures and users. The Land Use and Transportation Element also evaluates the road system necessary to serve that development, as well as alternative forms of transportation available to move people and goods and to provide facilities that complement and enhance the nature of the surrounding neighborhood. Designation 1 Environmental Element Covers the requirements of Conservation Element per Office of Planning and Research Guidelines. Page 69 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 5 of and access to evacuation routes based on the Land Use and Transportation Element is studied as a part of the Safety Element. The Housing Element details the City’s eight-year strategy for the enhancement and preservation of the community; identifies strategies for expanding housing opportunities for the City’s various economic segments; and provides the official policy guidance for local decision-making related to housing. Similar to the Land Use and Transportation Element, the Housing Element is related to the Safety Element for the evaluation and mitigation of proposed development in any hazard zones. California Government Code Section 65302 requires the Safety Element to be updated every time a Housing Element is updated. The Environmental Element sets policies and describes the natural resources of within the City including land, water, and ecosystem services. Essentially, it focuses on sustainable land use, resource management, and environmental protection. These are directly related to climate resiliency policies of the Safety Element. 1.1.2. County’s Operational Area Emergency Operations Plan The San Diego County Operational Area (OA) was formed in the 1960's to assist all of the cities and the County in developing emergency plans, exercising those plans, developing Mutual Aid capabilities between jurisdictions and, in general, establishing relationships that would improve communications between jurisdictions and agencies. The OA consists of the County and all jurisdictions within the county. The San Diego County Operational Area Emergency Operations Plan (OA EOP) is for use by the County and all of the cities within the county to respond to major emergencies and disasters. It describes the roles and responsibilities of all county departments (including many city departments), and the relationship between the County and its departments and the jurisdictions within the county. The Cities are encouraged to adopt the OA EOP as their own, with modifications as appropriate for their city. The Plan is subject to update every four years by the Office of Emergency Services and the Unified Disaster Council of the Unified San Diego County Emergency Services Organization. 1.1.3. City’s Vista Emergency Operations Plan The City’s Emergency Operations Plan (EOP) was updated in July 2021 and addresses Emergency Preparedness (those activities supporting enduring operational readiness) and Emergency Response (those immediate and ongoing actions that lead the jurisdiction through an identified crisis or disaster event). The goal of this plan is to provide for a coordinated effective response to ensure the protection of life, property, resources, and the environment. The City of Chula Vista EOP is based on the County of San Diego Operational Area Emergency Operations Plan (OA EOP). It is designed to meet the needs of the City with respect to organizational structure and identified hazards. It is fully integrated into the Safety Element and may be found at this location: /https://pub-chulavista.escribemeetings.com/filestream.ashx?DocumentId=35655. 1.1.4. County’s Multi-Jurisdictional Hazard Mitigation Plan The City of Chula Vista is a jurisdictional partner in San Diego County’s Multi-Jurisdictional Hazard Mitigation Plan (MJHMP). The MJHMP identifies ways to minimize damage from natural and human- Page 70 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 6 caused disasters. The plan is a resource for hazard management, state and federal program requirements, local hazard mitigation capability, and inter-jurisdictional coordination. The County’s MJHMP was revised in 2023 to include recent hazards and mitigation measures. San Diego County received an achievement award from the National Association of Counties for the original MJHMP drafted in 2004. The 2023 MJHMP was crafted in accordance with the Disaster Mitigation Act of 2000 and followed the Federal Emergency Management Agency’s (FEMA) 2011 Local Hazard Mitigation Plan guidance. The MJHMP incorporates a process where hazards are identified and profiled, the people and facilities at risk are analyzed, and mitigation actions are developed to reduce or eliminate hazard risk. The implementation of these mitigation actions, which include both short- and long-term strategies, involves planning, policy changes, programs, projects, and other activities. The MJHMP is fully integrated into the Safety Element and may be found at this location: https://www.sandiegocounty.gov/oes/emergency_management/oes_jl_mitplan.html 1.1.5. Climate Action Plan Since 2000, Chula Vista has been implementing a “Climate Action Plan” to address the threat of climate change impacts to the local community. Greenhouse gas (GHG) emissions represent a unique hazard because until the City reaches its net-zero goal community-wide actions will contribute to an increase in the hazards they cause and will only be reduced by global GHG emissions reductions. The most recent plan is the 2017 Climate Action Plan (CAP). It includes ambitious new goals and policies to strengthen the City’s climate action efforts. Implementing the CAP facilitates achieving numerous community co-benefits such as utility savings, better air quality, reduced traffic congestion, local economic development, and improved quality of life. It brings together past City of Chula Vista climate plan efforts including the original Carbon Dioxide Reduction Plan (2000), the mitigation plan (2008), and the adaptation plan (2011), and an updated plan is expected to be released in 2024. The City regularly conducts greenhouse gas emission inventories to help guide the execution of the CAP as well as to monitor and evaluate the progress. The CAP is fully integrated into the Safety Element and may be found at this location: https://www.chulavistaca.gov/home/showdocument?id=15586. 1.1.6. Sustainable Communities Strategy The Sustainable Communities Strategy (SCS) was adopted in 2021 as a part of the San Diego Association of Governments (SANDAG) 2021 Regional Plan and is designed to help create more sustainable and livable communities within the San Diego region.2 The SCS in San Diego, like in other regions of California, is largely driven by the requirements of Senate Bill (SB) 375, which was passed in 2008. SB 375 mandates that regions in California develop strategies to reduce greenhouse gas emissions from the transportation sector by integrating transportation, land use, housing, and environmental planning in order to improve air quality and enhance the overall quality of life for residents. Local jurisdictions, including Chula Vista, have agreed to certify that their general plans are consistent with the SCS. 2 San Diego Association of Governments, 2021 Regional Plan, https://www.sandag.org/- /media/SANDAG/Documents/PDF/regional-plan/2021-regional-plan/final-2021-regional-plan/final-2021-regional- plan-flipbook.pdf.

Existing Conditions An analysis of existing conditions is one of the primary steps in the process of updating the City of Chula Vista’s Safety Element. An outline of information on existing conditions in the City and surrounding areas, as well as an analysis of factors that will impact the City's physical development, will inform the goals, policies, and actions of the Safety Element. The existing conditions analysis for each identified hazard includes identifying the location and extent of hazard areas that currently exist an d have historically occurred as well as identifying the capabilities of the City to mitigate or respond to each hazard. The goals, policies, and implementation plan laid out in this Safety Element are guided by the existing conditions related to each hazard and safety risk. The focus of the identified existing conditions is on mappable resources, trends, and concerns that will frame choices for the long -term physical development of the City. 2.1.1. Planning Area The Safety Element relates to the entire City of Chula Vista, which is in San Diego County. San Diego County is located in southwestern California, bordering the Pacific Ocean and Mexico. The City is located in the southwestern portion of San Diego County along the San Diego Bay. The City is bordered by National City in the northwest, the City of San Diego farther northwest, and unincorporated San Diego County in the north and east. To the south of the City is the City of San Diego, followed by the US-Mexico Border. Because certain disaster events, geologic features, and potential hazards relate to each other and transcend the City's boundaries, this Safety Element takes into account hazards that occur or originate in other jurisdictions when the potential impact of those hazards might impact the City. There are no military installations in Chula Vista and hence the impacts of hazards on military installations are not discussed in this document. 2.2. Geologic Hazards San Diego County has a geologically diverse composition of alluvial fans, mountains, rivers, and streams, and is located along the San Diego Bay and Tijuana River Basin. Much of the City is characterized by sedimentary and volcanic rock. To the west is the San Diego Bay where the coastline includes habitats such as a salt marsh, mudflats, and salt flats. To the east is a lake and open space reserve. Major geological features of San Diego County include the San Diego Bay and Pacific Ocean to the west, the Tijuana River to the south, and the Anza Borrego Desert to the east. An understanding of the geology and soil composition of a site is essential for new construction and redevelopment of land as it can impact the safety of the structures. Geologic hazards include seismic hazards, landslides, subsidence, and expansive soils. Seismic hazards can lead to fault rupture, ground shaking, and liquefaction. Seismic activity can also be a cause of landslides, subsidence, tsunamis, and seiches. Table 1 and Figure 1 show the geologic makeup of Chula Vista. Large portions of the City on the east of Interstate 805 are composed of marine sedimentary rocks with high shale content and can be prone to Page 73 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 9 landslides when they become saturated with water, leading to reduced cohe sion. The presence of weak or poorly cemented sedimentary layers can contribute to landslide susceptibility. The soils in Chula Vista vary, with sandy soils near the coast and more clay-rich soils inland.

Seismic Hazards 2.2.1.1. Fault Rupture Earthquake severity is typically categorized according to magnitude (a measure of the amount of energy released when a fault ruptures) and seismic intensity (a qualitative estimate of the damage caused by an earthquake at a given location). Because the amount of destruction generally decreases with distance from the epicenter (the point at the earth's surface directly above where the earthquake originated), earthquakes are assigned several intensities. The most commonly used seismic intensity scale is the Modified Mercalli Intensity (MMI) scale, which has 12 levels of damage. The higher the number, the greater the damage. The largest earthquake that can occur on a fault or fault segment is called the maximum credible (MCE) or characteristic earthquake. Depending on the planned use, lifetime, or importance of a facility, a maximum probable earthquake (MPE) is the earthquake most likely to occur in a specified period (such as 30 to 500 years). In general, the longer the period between earthquakes on a specific fault segment (recurrence interval), the larger the earthquake. The State of California, under the guidelines of the Alquist-Priolo Earthquake Fault Zoning Act of 1972, regulates the development of structures near active faults. The California Department of Conservation classifies faults according to the following criteria: • Holocene-Active Fault: A fault that has had surface displacement within Holocene time (the last 11,700 years); • Pre-Holocene Fault: A fault whose recency of past movement is older than 11,700 years and thus does not meet the criteria of Holocene-active fault as defined in the State Mining and Geology Board regulations. An earthquake or rupture along one of the many faults in the vicinity of the City could result in casualties and extensive property damage. The impacts of such a quake may also result from aftershocks and secondary effects such as fires, landslides, dam failure, liquefaction, and other threats to public health and safety. California is a seismically active area with numerous faults throughout the region (see Figure 2). The City is situated on the Pacific Ring of Fire, which is a region of intense tectonic activity that circles the Pacific Ocean. Hence, Chula Vista is at risk for earthquakes and other geologic hazards. However, there are no State- designated Alquist-Priolo Earthquake Fault Zones per Geological Survey within the City where surface fault rupture previously has occurred, or where local topographic, geological, and geotechnical conditions indicate a potential for permanent ground displacements such that mitigation by avoidance as stated in Public Resources Code Section 2621.5 would be required. The closest major fault system in the region is the Rose Canyon fault, approximately 14 miles northwest, and the Elsinore Fault on the east. Local faults also include the Sweetwater Fault and La Nacion Fault to the south of the City as shown in Figure 3. Rose Canyon Fault: The Rose Canyon Fault is an extension of the Los Angeles Newport-Inglewood Fault and is a right-lateral, strike-slip fault. The last major earthquake along the Rose Canyon Fault occurred in 1862 with a magnitude of 6. The earthquake caused minor damage to Old Town San Diego and resulted in a tsunami in San Diego Bay. Elsinore Fault: The Elsinore Fault extends for approximately 180 kilometers through Southern California. However, despite its size, it is one of the quietest faults in the region and is called a sleeping giant. It is known to be seismically active, and it has the potential to generate significant earthquakes. While it may not be as Page 76 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 12 well-known as other fault systems in California, it remains a source of concern for earthquake hazards in the region. It is a strike-slip fault, which means that it primarily exhibits horizontal movement along the fault plane. La Nacion Fault: The La Nacion Fault is situated to the east of San Diego Bay, within the broader Southern California region. It runs through the Tijuana River Valley to the south of the City and is made up of north- south oriented faults that dip to the west, appearing like a network of connected lines. These faults have moved the rocks of the Pliocene San Diego Formation by more than 60 meters over time. There has been no recent movement on these faults. Sweetwater Fault: The Sweetwater Fault is situated in the southern part of San Diego County, near Chula Vista and the Sweetwater Reservoir. It is part of the broader fault system in Southern California. The Sweetwater Fault is known to be a strike-slip fault. The Sweetwater Fault is considered one of the significant seismic hazards in the region and it has the potential to produce earthquakes that could impact local communities, including Chula Vista. 2.2.1.2. Ground Shaking Ground shaking is characterized by the physical movement of the land surface during earthquakes. This shaking can cause significant damage to buildings and impact the underlying soils. Strong ground shaking as a result of earthquakes can cause soils to compact, resulting in local or regional subsidence of the ground surface. During strong ground shaking, soils become more tightly packed due to the collapse of pore spaces, resulting in a reduction in the thickness of the soil column. This type of ground failure typically occurs in loose granular, cohesionless soils and can occur in either wet or dry conditions. Unconsolidated young alluvial deposits are especially susceptible to this hazard. Damage to structures can occur as a result of subsidence. Portions of the City may be susceptible to seismically induced settlement. The City of Chula Vista is not listed within a State-designated Alquist-Priolo Earthquake Fault Zone. The closest fault in the region is the Rose Canyon fault, approximately 14 miles northwest. San Diego County has a geologically diverse composition of alluvial fans, which may be susceptible to ground shaking. Shake Potential Figure 4 shows the shake potential in the City. It shows the relative intensity of ground shaking from anticipated future earthquakes. Percentage of gravity (% g) is a method for expressing acceleration, measured relative to gravity (g). Shaking potential at 150% of gravity would be 1.50 g's, perceived as severe ground shaking with moderate to heavy potential of damage on the Modified Mercalli Intensity scale. Based on the shake potential map, the strongest ground shaking that could occur in the City would be 1.35 to 1.75 g’s (135% to 175% of gravity), with higher shake potential in the most western areas of the City. For comparison purposes, the peak ground acceleration in a single direction measured during the 1994 Northridge earthquake was 1.82 g, moment magnitude 6.7—this was the highest ever instrumentally recorded in urban North America.3 3 Yegian, M. K., G. V. Ghahraman, G. Gazetas, P. Dakoulas, and N. Makris, “The Northridge Earthquake of 1994: Ground motions and Geo Technical Analysis,” Proceedings, 1995, Volume III, https://web.archive.org/web/20130506100941/http://www.coe.neu.edu/Depts/CIV/faculty/myegian/library/Thenorthridge%20Earthquake%2 0of%201994%20Ground%20Motions%20and%20Geotechnical%20Aspects.pdf. Page 77 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 13 These shake potential maps show the projected maximum capacity for ground shaking in the specific geography, based on conditions such as topography, soil types, groundwater location, etc. Areas around floodplains or shallow groundwater can experience more significant ground shaking, along with steep hillsides. 2.2.1.3. Liquefaction Seismic ground shaking of relatively loose, granular soils that are saturated or submerged can cause the soils to liquefy and temporarily behave as a dense fluid. Liquefaction is caused by a sudden temporary increase in pore water pressure due to seismic densification or other displacements of submerged granular soils. Liquefaction more often occurs in earthquake-prone areas underlain by young (i.e., Holocene age) alluvium where the groundwater table is higher than 50 feet below the ground surface. Chula Vista’s General Plan area is situated within seismically active Southern California. While no known Alquist-Priolo Earthquake Fault Zones or active faults (i.e., faults that exhibit evidence of ground displacement during the last 11,000 years) traverse Chula Vista, traces of the potentially active La Nacion Fault zone are known to cross the City in a generally north-south direction within the central portion of the City (refer to Figure 3). The greatest magnitude earthquake expected on the La Nacion fault is estimated to be 6.0. The nearest active faults are the Rose Canyon Fault, located approximately 14 miles northwest of the City, and the Coronado Bank fault, located approximately 30 miles from the City. Other active faults in the region are located more than 60 miles from the City. Strong vibrations due to earthquakes can cause liquefaction of certain soil types. Areas of Chula Vista in close proximity to San Diego Bay and the Sweetwater and Otay River Valley (refer to Figure 5) have shallow groundwater tables and poorly consolidated granular sediments potentially subject to seismically induced liquefaction. Seismic activity within the region can cause structures to fail, resulting in significant property damage, business disruptions, injuries, and even loss of life. Liquefaction-prone areas within the City are generally located along the coast of the San Diego Bay in the west, and surrounding the northern and southern boundaries of the City, as shown in Figure 5. These areas are classified as having liquefaction potential. In general, hazards associated with seismic activity include strong ground motion; ground surface rupture; liquefaction; and seismically induced settlement. Ground surface rupture is not considered likely to occur in the City’s General Plan area. Lurching or cracking of the ground surface as a result of nearby or distant seismic events is also considered unlikely.

Landslides A landslide is defined as the movement of a mass of rock, debris, or earth movement down a slope. Landslides are subdivided by the type of geologic material (bedrock, debris, or earth). Debris flows (commonly referred to as mudflows or mudslides) and rock falls are examples of common landslide types.4 Landslides can be initiated in slopes already on the verge of movement by rainfall, snowmelt, changes in water level, stream erosion, changes in groundwater, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors. Landslide susceptibility is defined as the likelihood of a landslide occurring in an area on the basis of local terrain conditions. Initiates are not taken into account when determining landslide susceptibility, as the cause of an area being susceptible to landslides is not the same as the cause of a landslide. While rainfall is not a cause of landslide susceptibility, it is a potential initiate of landslides. Average yearly rainfall in Chula Vista has been decreasing in recent years, however dry weather may lead to increased wildfire risk. Wildland fire risk zones have steep slopes and limited precipitation, Since Chula Vista receives limited precipitation, the potential for wildland fires represents a significant hazard within areas of the City. Per the California Department of Conservation, slopes are more susceptible to debris flow after wildfire. Therefore, landslide susceptibility may increase as a result of more frequent fires. Areas of known landslides, or areas generally susceptible to landsliding, within the General Plan area have been identified in Figure 6. The potential for earthquake-induced landsliding in hillside terrain is also present. Slopes steeper than 25 degrees (approximately 2:1) are potentially subject to instability. Such areas may be prone to hazards such as surficial failures; earthflows; debris flow; mudslides; rock falls; soil creep; and erosion. Failures of man-made slopes could also occur in some of the developed areas of the City. Planning for a safe community requires consideration of geologic hazards. Incorporating proper geotechnical engineering techniques in development projects can reduce the risks associated with geologic hazards to an acceptable level. The State Historical Building Code is a tool that is available to the City to ensure the reasonable safety of historically significant buildings from geologic hazards while facilitating the maintenance of the historical integrity of such buildings. Figure 6 shows the relative likelihood of deep-seated landsliding based on regional estimates of rock strength and steepness of slopes. On the most basic level, weak rocks and steep slopes are most likely to generate landslides. The map uses detailed information on the location of past landslides, the location and relative strength of rock units, and the steepness of the slope to estimate susceptibility to deep-seated landsliding. This landslide susceptibility map is intended to provide infrastructure owners, emergency planners, and the public with a general overview of where landslides are more likely to occur. However, it is essential to note that this map is not suitable for assessing the landslide risk at any particular location. The analysis of landslide susceptibility uses a combination of rock strength and slope data to create classes of landslide susceptibility from 0 (low) to 10 (high). These classes express the generalization that on very low 4 US Geological Survey, “What is a landslide and what causes one?” accessed October, 12, 2022, https://www.usgs.gov/faqs/what-landslide-and- what-causes-one. Page 83 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 19 slopes, landslide susceptibility is low even in weak materials and that landslide susceptibility increases with slope and in weak rocks. The landslide susceptibility matrix is based on Rock Strength and Slope Steepness.5 Areas underlain by shale and siltstone are more prone to landslides when compared to other bedrock geology, which is more prone to slow-developing, slump-type failure. The areas in the north and southeast portions of the City with steeper slopes are more vulnerable to landslides. Areas along Olympic Parkway and Telegraph Canyon Road also have higher susceptibility with a few parcels reaching a susceptibility of 10. Any development of areas in the higher landslide susceptibility areas will need a geological assessment to determine the mitigation measures appropriate for these areas. Engineering techniques such as constructing retaining walls or reinforced retaining structures, creating terraces, installing proper drainage systems, and using rock bolts to secure loose rocks or soil can be explored as mitigation measures. In addition, native vegetation with deep roots to bind the soil and reduce erosion as well as limiting development in high-risk landslide areas may be effective in preventing landslides. No indications of past landslides have been observed. 2.2.3. Subsidence Ground subsidence is the gradual settling or sinking of the ground surface with little or no horizontal movement. Most ground subsidence is anthropogenic (i.e., originating in human activity) and is usually associated with the extraction of oil, gas, or groundwater from below the ground surface in valleys filled with recent alluvium. Land subsidence can also occur during an earthquake because of offset along fault lines and as a result of settling and compacting of unconsolidated sediment from the shaking of an earthquake. The United States Geological Survey (USGS) documents areas of land subsidence throughout California, including historical and current subsidence. The USGS has not identified any regional subsidence as a result of groundwater pumping or oil extraction in the City of Chula Vista or surrounding communities.6 2.2.4. Expansive Soils Expansive soils are those that have the ability to expand or contract, changing in volume based on their moisture content. They are typically composed of a form of expansive clay mineral that readily absorbs water and swells, leading to an increase in volume when wet and contraction/shrinkage when dry. This shrink-swell process can cause fatigue and crack for infrastructure or foundations placed directly on or within expansive soils. Structural damage may result over a long period of time, making it difficult to estimate the severity of long-term impacts. Expansive soils are typically rich in clay minerals, particularly montmorillonite and smectite. These minerals have the ability to absorb water and expand, which is the primary reason for the soil's volume changes. Large portions of the City are composed of Diablo clay soil (refer to Figure 7), which is an expansive soil. The shrink-swell characteristic of expansive soils can create challenges for construction, foundations, and infrastructure in areas where Diablo clay or similar expansive soils are present. Proper engineering and construction techniques are required to mitigate the potential problems associated with these soils. 5California Geological Survey, Layer: Landslide Susceptibility Classes (ID: 0), accessed July 11, 2022, https://gis.conservation.ca.gov/server/rest/services/CGS/MS58_LandslideSusceptibility_Classes/MapServer/0. 6 US Geological Survey, “Areas of Land Subsidence in California,” accessed August 20,2023, https://ca.water.usgs.gov/land_subsidence/california- subsidence-areas.html.

Tsunamis and Seiches A tsunami is a wave or series of waves generated by a large and sudden upward movement of the ocean floor, usually the result of an earthquake below or near the ocean floor, underwater landslides, or volcanic activity. This sudden displacement and force create waves that radiate outward in all directions away from their source, sometimes crossing entire ocean basins. A tsunami wave conceivably could have adverse effects on the coastal areas of Chula Vista. However, because the City is adjacent to a relatively protected part of San Diego Bay, the potential for significant wave damage is considered low. A seiche is defined as a standing wave oscillation in an enclosed or semi-enclosed, shallow to a moderately shallow water body to the basin, such as a lake, reservoir, bay, or harbor, due to ground shaking, usually following an earthquake. Seiches continue in a pendulum fashion after the cessation of the originating force, which can be tidal action, wind action, or a seismic event. Seiches are often described by the period of the waves (how quickly the waves repeat themselves) since the period will often determine whether adjoining structures will be damaged. The period of a seiche varies depending on the dimensions of the basin. Whether the earthquake will create seiches depends upon a number of earthquake-specific parameters, including the earthquake location (a distant earthquake is more likely to generate a seiche, compared to a local earthquake), the style of fault rupture (e.g., dip-slip or strike-slip), and the configuration (length, width, and depth) of the basin. Due to the San Diego Bay being a mostly enclosed body, seiches do pose a potential threat to the City of Chula Vista along the San Diego Bay shoreline. In the unlikely event of the development of noticeable seiches, it is conceivable that local areas adjacent to the Otay Lakes and the San Diego Bay could be impacted by wave activity. However, seiches have not been historically documented in the area.

Fire Hazards 2.3.1. Wildland Fires A wildfire is defined as an unplanned and unwanted wildland fire, including unauthorized human-caused fires, escaped wildland fire use events, escaped prescribed fire projects, and all other wildland fires where the object is to extinguish the fire. Wildfire is a natural part of the California ecosystem, helping to clear brush and debris, and is a necessary part of various species' life cycles. Lightning, accidents, or arson can spark wildfires. Wildfires are becoming more frequent or intense with climate change. Although the City is not generally prone to wildfire hazards except in certain areas, regional wildfires may become an increasing threat with climate change. City has considered OPR's Fire Hazard Technical Advisory in preparation of this section. Human activity has changed the buffer zone between urbanized and undeveloped areas, known as the wildland-urban interface, where naturally fire-prone landscapes abut developed neighborhoods. The natural setting of a wildland-urban interface can make these areas highly desirable places to live, and many of these areas in California are now developed. This development has brought more people into wildfire-prone areas. The availability of fuel and increasing encroachment into the wildland-urban interface have made wildfires a common and dangerous hazard in California. Structural conditions that may affect fire control include the type and use of a structure, roof covering, surrounding landscaping, and exposure to the building. Once a fire has started, several conditions influence its behavior, including fuel topography, weather, drought, and development. Certain conditions must be present for significant interface fires to occur. The most common conditions include hot, dry, and windy weather, the inability of fire protection forces to contain or suppress the fire, the occurrence of multiple fires that overwhelm committed resources, and a large fuel load (dense vegetation). Wildland fire risk zones are areas that have steep slopes, limited precipitation, and plenty of available fuel, or combustible plant material. Brush management is required to be undertaken in the City in areas where urban development interfaces with open space, in order to reduce fire fuel loads and reduce potential fire hazards. Since Chula Vista receives limited precipitation, the potential for wildland fires represents a significant hazard within areas of the City. In 2003, the Cedar fire burned about 280,000 acres of land, about 10 percent of which was in the City of San Diego and led to the evacuation and burning of thousands of homes. It started 25 miles east of San Diego in the Cleveland National Forest and crossed into San Diego the next day. The Cedar fire burned for three days. The City of Chula Vista was largely avoided as the fire stopped at Otay Lakes. In 2007, the Harris, Witch Creek, and Guejito fires merged and burned about 200,000 acres and thousands of homes in San Diego County. Over 500,000 people were evacuated. The Harris fire entered the City of Chula Vista from the east and covered much of the same area as the Cedar fire had four years earlier. 2.3.2. Fire Hazard Severity Zones The California Department of Forestry and Fire Protection prepares wildfire hazard severity maps based on fuels, terrain, weather, and other relevant factors. These zones, referred to as Fire Hazard Severity Zones (FHSZ), define the application of various mitigation strategies and influence how people construct Page 89 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 25 buildings and protect property to reduce the risk associated with wildland fires. While FHSZ does not predict when or where a wildfire will occur, they do identify areas where wildfires may be more likely to occur or be more severe, based on factors such as fire history, existing and potential vegetation that can serve as fuel, predicted flame length, blowing embers, terrain, and typical fire weather for an area. Zones are designated in varying degrees from moderate, high, and very high. There are three types of responsibility areas in California: Local Responsibility Area (LRA), State Responsibility Area (SRA), or Federal Responsibility Area (FRA). LRAs are incorporated jurisdictions such as cities, urban regions, and agricultural lands where the local government is responsible for wildfire protection. SRAs are those for which the State of California is financially responsible for the prevention and suppression of wildfires. FRAs are lands for which the federal government has legal responsibility for providing fire protection. The City of Chula Vista has Very High Fire Hazard Severity Zones (VHFHSZ) in the eastern side of the city and a section in the south. There are also sections of SRA and FRA which are in the northeastern corner of Chula Vista. SRA is the responsibility of CAL FIRE and FRA lands are the responsibility of the U.S. Forest Service. In the City of Chula Vista, fire protection is provided by the Chula Vista Fire Department. Fire stations are dispersed throughout the City while police facilities are centered in headquarters located in downtown Chula Vista as shown in Figure 15. The Public Safety Services section provides more details on location and programs by fire department services in the City.

Flooding 2.4.1. Major Sources of Flooding Flooding occurs when a waterway (either natural or artificial drainage channel) receives more water than it is capable of conveying, causing the water level in the waterway to rise. Depending on how long these conditions last and the amount of runoff the waterway receives in proportion to its capacity, the rising water level may eventually overtop the waterway’s banks or any other boundaries to the drainage area, resulting in flooding. Floods often occur during heavy precipitation events, when the amount of rainwater exceeds the capacity of storm drains or flood control channels. Floods can also happen when infrastructure such as levees, dams, reservoirs, or culverts fail or when a section of drainage infrastructure fails, and water cannot be drained from an area quickly enough. These failures can be linked to precipitation events (e.g., when water erodes a levee, allowing water to escape and flood nearby areas) or can be a consequence of other emergency situations (e.g., a dam collapsing due to an earthquake). Flooding associated with heavy rainfall episodes, as well as dam failure, poses a significant hazard to people and property. Although much less likely to occur, tsunamis and seiches also represent potential flood hazards in portions of Chula Vista in proximity to the San Diego Bay and the Otay Lakes. Furthermore, flooding can result in costly damage to private and public property and infrastructure; by damaging roadways and creating unsafe driving conditions, flooding also impedes traffic and disrupts business operations. Climate change may lead to more frequent or intense storm events, and it is likely that flooding would have a more significant effect on the City. Increasing the capacity of the City's drainage infrastructure would make the City more resilient to weather events linked to climate change. During severe rain seasons, low-lying areas along the floodplains of the Sweetwater and Otay Rivers and several of their tributaries, including Telegraph Canyon Creek, Poggi Channel, Salt Creek, and Jamul (Dulzura) Creek, as well as certain drainage facilities, may experience flooding. Dams, levees, reservoirs, and drainage channels have been constructed to control the drainage of much of the watershed for the General Plan area, thereby reducing the potential for hazardous flooding of developed areas. FEMA has delineated inundation areas for 100- and 500-year floods. Areas designated to be within the flood zone are shown in Figure 10. Flood hazard areas identified on the Flood Insurance Rate Map (FIRM) are identified as Special Flood Hazard Areas (SFHA). SFHAs are defined as the area that will be inundated by the flood event having a 1 percent chance of being equaled or exceeded in any given year. The 1 percent annual chance flood is also referred to as the base flood or 100-year flood. SFHAs are labeled as Zone A, Zone AO, Zone AH, Zones A1-A30, Zone AE, Zone A99, Zone AR, Zone AR/AE, Zone AR/AO, Zone AR/A1-A30, Zone AR/A, Zone V, Zone VE, and Zones V1-V30. Moderate flood hazard areas, labeled Zone B or Zone X (shaded), are also shown on the FIRM and are the areas between the limits of the base flood and the 0.2 percent annual chance (or 500-year) flood. The areas of minimal flood hazard, which are the areas outside the SFHA and higher than the elevation of the 0.2 percent annual chance of flood, are labeled Zone C or Zone X (unshaded). The city allows construction in flood zones pursuant to Chapter 14.18 of the municipal code. Page 92 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 28 There are Zone A, and AE flood risk areas along San Diego Bay and on the northern and southern boundaries of the City. Areas at risk generally have low levels of development and include parks and open spaces. A Zone (A): This SFHA designation represents areas with a 1 percent annual chance of flooding, often referred to as the 100-year floodplain. It means that there is a 1 percent probability of a flood of this magnitude occurring in any given year. These areas typically have a higher risk of flooding and are subject to certain building and development restrictions, as well as requirements for flood insurance if a property owner has a federally backed mortgage. AO Zone (AO): The AO Zone is also an SFHA, but it is slightly different from the A Zone in that an AO Zone is an area that has a 1 percent annual chance of shallow flooding (typically with depths between 1 and 3 feet). These areas are also considered high risk, but the flooding is characterized by shallow depths rather than deep inundation. As with the A Zone, properties in the AO Zone may be subject to specific building and development regulations and requirements for flood insurance. AE Zone (AE): Similar to the A Zone, the AE Zone designates areas with a 1 percent annual chance of flooding, or the 100-year floodplain. The AE Zone is one of the most common flood zone designations. Properties within the AE Zone are subject to specific building and development regulations, including requirements for elevating structures above the base flood elevation to reduce flood risk. Property owners in AE Zones are also often required to have flood insurance if they hold federally backed mortgages. VE Zone: The VE Zone is a coastal high-hazard area that signifies a significant risk of flooding from a combination of wave action and storm surge. These areas are typically located along coastlines and are subject to increased vulnerability to flooding during hurricanes, tropical storms, and other coastal weather events. The VE designation is used to denote Velocity Zone, indicating that not only is flooding a concern, but also the speed and force of floodwaters, such as from waves and storm surges. Properties within VE Zones face specific building and development regulations, and they often require structures to be elevated on pilings or other appropriate foundations to mitigate the risk of damage from the combination of floodwaters and wave action.

Dam Inundation Dam failure is the uncontrolled release of impounded water from behind a dam. Flooding, earthquakes, blockages, landslides, lack of maintenance, improper operation, poor construction, vandalism, and terrorism can all cause dam infrastructure to fail. Dam failure causes downstream flooding of varying velocities that can result in loss of life and property. Several regional reservoirs and dams are located within and in the vicinity of Chula Vista. Of these, Sweetwater Dam, Savage Dam, and Lake Loveland have the potential to cause damage in the City if there is a breach. Savage Dam, built in 1919, is a 149-foot-high and 750-foot-wide dam. It is owned by City of San Diego and used for storing water for backup uses in the San Diego area. The Loveland Dam was built in 1945 and is owned and operated by the Sweetwater Authority; it is 203 feet high and 765 feet wide. In addition to its role in water supply, the Loveland Reservoir area offers recreational opportunities for the public. The surrounding lands are used for hiking, picnicking, birdwatching, and enjoying the natural beauty of the region. It is a popular spot for outdoor enthusiasts and nature lovers. The Sweetwater Dam was built in 1888 and is an important historical landmark in San Diego County. It is a 112-foot-high and 700-foot-wide dam. It is owned by the Sweetwater Authority and is part of their water supply system. It was built primarily to store and supply water for agricultural purposes and to support the growing population in the area. According to the California Department of Water Resources, Division of Safety of Dams (DSOD), the downstream hazard from Sweetwater Dam, Savage Dam, and Lake Loveland is classified as extremely high. The downstream hazard is based solely on potential downstream impacts to life and property should these dams fail when operating with a full reservoir and is expected to cause considerable loss of human life or result in an inundation area with a population of 1,000 or more. The DSOD also maintains a record of the condition assessment of the dams. According to a September 2022 report by DSOD, the condition assessment of Lake Loveland is satisfactory, meaning no existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines. The condition assessment for Sweetwater Dam is fair, meaning no existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. The risk may be in the range to take further action. The condition assessment for Savage Dam is poor, meaning a dam safety deficiency is recognized for normal operating conditions that may realistically occur. Remedial action is necessary. The classification of poor may also be used when uncertainties exist as to critical analysis parameters that identify a potential dam safety deficiency. Investigations and studies are necessary.7 Figure 11 depicts areas subject to flood inundation in the event of failure of the Sweetwater, Upper Otay, or Savage (Lower Otay) Dams. Dams typically fail due to overtopping by reservoir water during heavy rainfall episodes, structural damage, and earthquake-related hazards such as landsliding, ground shaking, and seiches. 7 California Department of Water Resources, Division of Safety of Dams, “Dams within Jurisdiction of the State of California: Dams Listed Alphabetically By County,” 2022, https://water.ca.gov/-/media/DWR-Website/Web- Pages/Programs/All-Programs/Division-of-Safety-of-Dams/Files/Publications/Dams-Within-Jurisdiction-of-the- State-of-California-Listed-Alphabetically-by-Name-September-2022.pdf.

Drainage System The City is located in the San Diego Bay watershed. A watershed, also known as a drainage basin or catchment area, is an area of land where all the water, including rainfall and runoff, drains into a common outlet, such as a river, lake, or ocean. The San Diego Bay watershed includes about 30 percent of San Diego County. The watershed includes Cities of Imperial Beach, Chula Vista, Coronado, La Mesa, Lemon Grove, National City, and San Diego, as well as unincorporated areas of San Diego County. The watershed supplies potable water and supports recreational activities. The San Diego Bay watershed is divided into Pueblo, Sweetwater, and Otay watersheds. Of these, the Sweetwater and Otay watersheds cover Chula Vista (refer to Figure 12). • Sweetwater River Watershed: The Sweetwater River is a prominent water body in the Chula Vista area. It flows through the City and has its headwaters in the mountains to the east. The Sweetwater River watershed includes the land area that drains into the river. The river and its watershed play a significant role in the region's water supply and ecology. • Otay River Watershed: The Otay River flows through the southern part of Chula Vista and serves as the boundary between the United States and Mexico for a portion of its course. The Otay River watershed includes the land area that drains into the Otay River. It is an important watercourse in the region. These watersheds are essential for managing stormwater, providing recreational opportunities, and maintaining water quality in the Chula Vista area. The City participates in San Diego County’s Project Clean Water and coordinates with other communities in the County on matters of clean water and stormwater.

Climate Change and Resilience Climate resilience is the capacity of communities to withstand, adapt to, and recover from the adverse impacts of climate change. Climate change is a phenomenon characterized by the long-term shifts in global temperature and weather patterns associated with the build-up of greenhouse gases in the atmosphere and the warming of the planet due to the greenhouse effect. Although climate change is global, its effects can be felt locally, and the response also can start locally. Local policies and actions can reduce greenhouse gas emissions from local sources and incorporate resilience and adaptation strategies into planning and development. Climate change can have widespread effects on temperature and weather patterns, creating conditions that may make storms more frequent or more intense, resulting in more intense rainfall and flooding. Climate change also contributes to sea level rise, intensifying coastal hazards. In many areas, climate change may increase the frequency and duration of droughts and create conditions that intensify wildfire vulnerability. 2.5.1. Climate Change The California Natural Resources Agency’s Cal-Adapt tool is an online platform designed to provide data, information, and resources related to climate change impacts in California. Table 2, created from the Cal- Adapt tool, shows the changes specific to Chula Vista. As shown, the number of extreme heat days, increase in annual maximum temperatures, and decrease in annual precipitation may be a cause of concern for the City. Table 2: Local Climate Change Snapshot Climate Change Factors Impacting the City Observed (1961- 1990) Mid-Century (2035-2064) Medium EmissionsA High EmissionsA Annual Average Maximum Temperature (°F) 71.0 - 71.7 72.6 – 76.0 73.1 – 76.5 Extreme Heat Days (days)B 2 – 4 5 – 16 6 – 20 Annual Precipitation (inches) 1.1 – 1.3 1.0 – 1.5 1.0 – 1.6 Annual Average Area Burned (acres)C 247.5 – 290.1 279.0 – 335.6 303.2 – 344.1 A.

Extreme Heat An extreme heat event occurs between April and October when the temperature is at or above the 98th Percentile for historic daily maximum temperatures in Chula Vista. An increase in extreme heat waves can increase the risk of heat stroke or dehydration. Extreme heat may strain water, power, and transportation Page 99 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 35 systems. Extreme heat can also have negative effects on infrastructure such as roadways and sidewalks, leading to deterioration and buckling. Additionally, the increased use of air conditioners used by extreme heat events can put strain on electrical systems and lead to emissions which effect lung function over time. 2.5.3. Sea Level Rise As the City of Chula Vista includes approximately 5 miles of coastline along the San Diego Bay, the City is potentially vulnerable to future sea level rise. The San Diego Bay receives water from Sweetwater River, Otay River, and Chollas Creek, and is connected to the Pacific Ocean. Sea level rise is a climate change- driven phenomenon of increasing the elevation of the ocean surface. According to the National Oceanic and Atmospheric Administration (NOAA), sea level rise at the regional level can deviate significantly from the globally averaged rate.8 Thus, effects are unique to specific coastal jurisdictions due to variations in topography and geography. Sea level rise projections and modeling referenced in Table 3 rely on the best available science as evaluated by the California Coastal Commission’s 2018 Sea Level Rise Policy Guidance and are supplemented by NOAA’s 2022 Sea Level Rise Technical Report. Figure 13 shows a scenario assuming 3 feet of sea level rise. In such a scenario, only a few segments of the Chula Vista coastal area will be inundated. These areas are currently undeveloped and are expected to remain so in the future. Table 3: California Coastal Commission Sea Level Rise (SLR) Projections YEAR Low Risk Aversion Medium-High Risk Aversion Upper limit of “likely range” ~17% probability SLR exceeds… 1-in-200 chance 0.5% probability SLR exceeds… 2050 1.2 feet 2.0 feet 2070 2.0 feet 3.6 feet 2090 3.0 feet 5.7 feet 2100 3.6 feet 7.0 feet NOTE: The California Coastal Commission and NOAA state available climate models and experiments do not extend beyond 2100. Both agencies acknowledge increased uncertainties regarding projections past 2100 and recommend caution if projections require utilization. Source: California Coastal Commission, Sea Level Rise Policy Guidance – Science Update, adopted November 2018. In addition, groundwater emergence which refers to the flooding or inundation caused by the emergence of groundwater at the land surface, is anticipated to accompany future sea level rise impacts. As sea levels rise, saltwater can intrude into groundwater aquifers that store fresh water. If the amount of saltwater intrusion is great enough, groundwater can be pushed to the surface.9 Specific vulnerabilities to a rising water table and groundwater emergence include dry weather flooding, deterioration of underground infrastructure such as water/sewer pipelines, extended earthquake liquefaction zones, and resurfacing any underground toxic contamination.10 8 National Ocean Service/National Oceanic and Atmospheric Administration, 2022 Sea Level Rise Technical Report, https://oceanservice.noaa.gov/hazards/sealevelrise/sealevelrise-tech-report-sections.html. 9 MIT Technology Review, Climate Change: How Groundwater caused by Climate Change could Devastate Coastal Communities, 2021, https://www.technologyreview.com/2021/12/13/1041309/climate-change-rising-groundwater-flooding/. 10 KQED, Groundwater Beneath Your Feet Is Rising With the Sea.

Resilience Resiliency in the face of climate change refers to the actions that can be taken to reduce the drivers of climate change and actions to mitigate the effects of climate change. This includes making our community is more resilient to impacts of climate change but also reducing those impacts by reducing GHG emissions and achieving the City’s net zero goal. Because climate change is a long-term phenomenon, it is important to adequately plan for its impacts. In order to mitigate the effects of intense storms, actions may include bolstering drainage capacities and flood control measures. With more frequent or intense storm events, it is likely that flooding would have a more significant effect on the City. Increasing the capacity of the City's drainage infrastructure would make the City more resilient to weather events linked to climate change. Climate change resiliency would also include measures to reduce vulnerability to droughts and wildfires. This may include water conservation and water supply management efforts to ensure the City is prepared in the event of a long-term drought. Diversifying the City's water supply by introducing and maintaining water sources that are less susceptible to drought or are more sustainable also accomplishes this goal. The City does not own or maintain any water supply. The City is dependent on 3 water agencies for its water supply. The City could implement conservation efforts but these efforts do not guarantee a reserve supply of water for the City during drought periods. Additionally, as wildfires become more frequent or intense with climate change, actions to mitigate the City's vulnerability may be warranted. Although the City is not generally prone to wildfire hazards, regional wildfires may become an increasing threat with climate change. 2.5.5. Vulnerability Assessment Summary The County’s MJHMP (2023) documents the hazards for the City of Chula Vista and provides a vulnerability assessment of these threats. Facilities that provide critical and essential services following a major emergency are of particular concern because these locations house staff and equipment necessary to provide important public safety, emergency response, and/or disaster recovery functions. Considering the critical facilities identified in Figure 14 and Figure 15 the climate-related threat that the structures are most vulnerable to is wildfire. Some structures located in the northern portion of the City are also vulnerable to flooding, dam inundation, and liquefaction. The critical facilities are also vulnerable to earthquakes. The secondary impacts of earthquakes could be magnified by climate change. Soils saturated by repetitive storms could fail prematurely during seismic activity due to the increased saturation. 2.5.6. Critical Facilities Critical facilities in a city are those essential structures, services, and resources that are vital for the well - being and functioning of the community, particularly during and after disasters or emergencies. These facilities are considered critical because their disruption or damage can have severe consequences for public safety, health, and the overall recovery of the community. Table 4 provides the list of various critical facilities as identified by the City’s Public Works department. Figure 14 and Figure 15 show the location of these critical facilities.

Drought Drought is defined as an extremely dry climatic period where the available water falls below a statistical average for a region. Drought is also defined by factors other than rainfall, including vegetation conditions, agricultural productivity, soil moisture, water levels in reservoirs, and streamflow. Droughts or water shortages are a gradual phenomenon, occurring over multiyear periods and increasing with the length of dry conditions. When precipitation is less than normal for a period of time, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth to water in wells increases. If dry weather persists and water supply problems develop, the dry period can become a drought. The term "drought" can have different meanings depending on how a water deficiency affects day-to-day activities. Drought is a complex natural hazard, which is reflected in the following four definitions commonly used to describe it: • Agricultural – Agricultural drought is defined principally in terms of naturally occurring soil moisture deficiencies relative to water demands of plant life, usually arid crops. • Hydrological – Hydrological drought is related to the effects of precipitation shortfalls on stream flows and reservoir, lake, and groundwater levels. • Meteorological – Meteorological drought is defined solely on the degree of dryness, expressed as a departure of actual precipitation from an expected average or normal amount based on monthly, seasonal, or annual time scales. • Regulatory (or socioeconomic) – Regulatory drought can occur when the availability of water is reduced due to the imposition of regulatory restrictions on the diversion and export of water out of a watershed to another area. Although the climate is a primary contributor to hydrological drought, other factors such as changes in land use (i.e., deforestation), land degradation, and the construction of dams can affect the hydrological characteristics of a region. Because regions are geographically interconnected by natural system s, the impact of meteorological drought may extend well beyond the borders of the precipitation-deficient area. Changes in land use upstream may alter hydrologic characteristics such as infiltration and runoff rates, resulting in more variable streamflow and a higher incidence of hydrologic drought downstream. Land use change is one way that human actions can alter the frequency of water shortage even when no change in precipitation has been observed. Droughts cause public health and safety impacts, as well as economic and environmental impacts. Public health and safety impacts are primarily associated with catastrophic wildfire risks and drinking water shortage risks for small water systems in rural areas and private residential wells. Examples of other impacts include costs to homeowners due to loss of residential landscaping, degradation of urban environments due to loss of landscaping, agricultural land fallowing, and associated job loss, degradation of fishery habitat, and tree mortality with damage to forest ecosystems. Drought conditions can also result in damage to older infrastructure that is located within dry soils with the potential to leak or break. Dead or dying vegetation poses a risk of falling and damaging structures and infrastructure systems. Climate change may increase vulnerability to droughts. Water conservation and water supply management efforts would help ensure the City is prepared in the event of a long-term drought. The City Page 108 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 44 could implement conservation efforts but these efforts do not guarantee a reserve supply of water for the City during drought periods. 2.6.1. Drought Severity Drought severity depends on numerous factors, including duration, intensity, and geographic extent, as well as regional water supply demands by humans, animals, and vegetation. The severity of drought can be aggravated by other climatic factors, such as prolonged high winds and low relative humidity. The magnitude of drought is usually measured in time and the severity of the hydrologic deficit. The US Drought Monitor is a map released weekly that indicates the portions of the United States that are experiencing drought and the severity of the drought based on five classifications: abnormally dry (D0), showing areas that may be going into or are coming out of drought, and four levels of drought: moderate (D1), severe (D2), extreme (D3), and exceptional (D4) (refer to Table 5). The Drought Monitor is not a forecast but looks backward, providing a weekly assessment of drought conditions based on how much precipitation did or did not fall. Because drought is a slow-moving hazard, it may take more than one good rainfall to end a drought, especially if an area has been in drought for a long time. Table 5: Drought Severity Classification Category Description Possible Impacts D0 Abnormally Dry Going into drought: short-term dryness slowing planting, growth of crops or pastures. Coming out of drought: some lingering water deficits; pastures or crops not fully recovered. D1 Moderate Drought Some damage to crops, pastures, streams, reservoirs, or wells is low. Some water shortages are developing or imminent; voluntary water-use restrictions are requested. D2 Severe Drought Crop or pasture losses likely; water shortages common; water restrictions imposed. D3 Extreme Drought Major crop/pasture losses; widespread water shortages or restrictions. D4 Exceptional Drought Exceptional and widespread crop/pasture losses; shortages of water in reservoirs, streams, and wells create water emergencies.

Based on a map released on September 21, 2023, 93.53 percent of California is not in drought compared to 0 percent at this same time last year. None of the areas are in the D2 to D4 categories compared to 94 percent a year ago. Only 6.5 percent fall into in the D0 and D1 categories (see Figure 16).11 11 US Drought Monitor accessed September 25, 2023, https://droughtmonitor.unl.edu/CurrentMap/StateDroughtMonitor.aspx?CA.

In a drought, all areas of Chula Vista will be affected. According to the US Drought Monitor, there is no extreme (D3) or exceptional drought (D4) in California . California has not seen D1/D0 only conditions since March 2020. California experienced 31 atmospheric rivers in water year (WY) 2023 through March, which delivered between 1.5 to 2 WYs' worth of precipitation in much of the state. The region has been extremely cool this WY, and in particular, much of the region in the last three months from the date of this writing, experienced temperatures 3–9 degrees below normal. This has helped to maintain the snowpack. The precipitation from December 2022 to March 2023 alleviated much of the precipitation deficit in the California central and south coast region. 2.6.2. California Drought History Drought has affected virtually every county in California, and California has experienced numerous severe droughts over the past century. FEMA declared one drought emergency for California in January 1977, and other drought emergency declarations have been declared by the state.12 According to the 2018 State Hazard Mitigation Plan, from 1972 to 2016, there were fifteen drought state emergency proclamations in California.13 The most severe drought on record began in 2012 and continued through 2017. On January 17, 2014, the governor of California declared a state drought emergency, and on April 1, 2015, the governor announced the first-ever mandatory 25 percent statewide water use reduction and a series of actions to help save water, increase enforcement to prevent wasteful water use, streamline the state's drought response, and invest in new technologies that would make California more drought resilient. At the time of the announcement, the volume of the Sierra Nevada snowpack was approximately 14 percent of normal. Despite multiple storms in February 2014, drought conditions persisted. By the end of May 2014, all of California was in a condition of "extreme" or "exceptional" drought. At the same time, the volume of the Sierra Nevada snowpack had decreased to less than 10 percent of normal, and water stored in Lake Oroville, the major reservoir for the State Water Project, was at 58 percent of normal.14 On April 7, 2017, the governor issued an executive order ending the drought emergency in most of California, including San Diego County.

California Department of Water Resources, California's Most Significant Droughts: Comparing Historical and Recent Conditions, 2015. 2.6.3. Water Supply Chula Vista residents receive their water supply for both drinking and emergency from three water districts, depending on their specific location within the City. The primary water agencies serving different parts of Chula Vista are: • Sweetwater Authority: Sweetwater Authority is the primary water agency that serves a significant portion of Chula Vista. It provides water to the western and central areas of the City, including much of the residential and commercial areas. Due to the lack of significant undeveloped land area within the boundaries of the Sweetwater Authority's service area, future increases in the demand for potable water will be associated with infill development and redevelopment projects. Water delivered to Sweetwater Authority consumers is obtained from a variety of sources. Approximately 70 percent of its water is from local water supplies, including the Sweetwater River and the San Diego Groundwater Formation. The remainder is obtained from imported water sources such as groundwater wells, local reservoirs, and imported water San Diego County Water Authority (CWA). • Otay Water District: The Otay Water District serves the eastern parts of Chula Vista, including areas near the Otay Lakes and eastern neighborhoods. It provides water to residents and businesses in this part of the City. Otay Water District also currently has one of the largest recycled water distribution systems in San Diego County. Water is recycled at the South Bay Water Reclamation Plant located in San Ysidro. All potable water comes from imported sources purchased from the San Diego CWA. • California-American Water: Certain parts of western Chula Vista receive water service from the California-American Water Company. Areas served by the Cal-American Water Company are presently built out and significant growth in water demand is not anticipated. Page 112 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 48 Figure 17: California American Water Service Area Map Page 113 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 49 The San Diego CWA generally imports 75–95 percent of this water from the Metropolitan Water District (MWD) of Southern California. Water imported to the region comes from two primary sources: the Colorado River, through the 240-mile Colorado River Aqueduct; and the State Water Project from Northern California, through the Sacramento-San Joaquin River Delta and the 444-mile California Aqueduct. These sources deliver water to the MWD, which then distributes water supplies to districts throughout the Southern California region, including the San Diego CWA. The CWA is composed of 23- member water agencies and water districts, including two that serve Chula Vista: the Otay Water District and Sweetwater Authority. A third water agency, Cal-American, also provides water to a small portion of the Chula Vista planning area but is not a member of the CWA. The three districts vary in size and age of infrastructure but are all expected to conform to the same quality and service standards established by the California Department of Public Health and the federal Clean Water Act. In addition to providing water supplies, these agencies provide emergency storage systems and implement conservation efforts. The California Water Code requires all urban water suppliers within the state to prepare urban water management plan(s) and update them every five years, in years ending in five or zero. The plans are to identify supply and demand, infrastructure, and funding. In accordance with state law, the CWA updated its Urban Water Management Plan (UWMP) in 2020. The 2020 UWMP identifies a diverse mix of water resources planned to be developed over the next 25 years to ensure that the region has enough water to meet its needs, including during drought periods. Chula Vista has adopted a landscape water conservation ordinance as required by state law and the California Department of Water Resources’ Water Efficient Landscape Ordinance. In addition, the City's Landscape Manual requires the use of recycled water to irrigate landscaped areas of residential, commercial, and industrial developments, as well as schools, parks, and golf courses, where recycled water is available. 2.7. Hazardous Materials A "hazardous material" is defined by California Health and Safety Code Section 25501 as "any material that, because of its quantity, concentration, or physical or chemical characteristics, poses a significant present or potential hazard to human health and safety or to the environment if released into the workplace or the environment." Improper handling of hazardous materials or waste may result in significant impacts on human health and the environment. Hazardous materials can be in the form of explosives, flammable and combustible substances, poisons, and radioactive materials. Hazardous materials accidents can occur during production, storage, transportation, use, or disposal. The impacts of a hazardous materials release can vary, depending on the type and amount of material released. Hazardous materials exposure can include the following effects: skin/eye irritation; difficulty breathing; headaches; nausea; behavior abnormalities; cancer; genetic mutations; physiological malfunctions (i.e., reproductive impairment, kidney failure); physical deformations; or birth defects. Many businesses and residents in the City use hazardous materials and generate some amount of hazardous waste. Common hazardous waste is generated from gasoline service stations, dry cleaners, automotive mechanics, auto body repair shops, machine shops, printers, photo processors, and agriculture. Page 114 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 50 2.7.1. Hazardous Materials Incidents Potential threats from hazardous materials exist where they are manufactured, stored, transported, or used due to the risk of spill and exposure to hazardous materials. The magnitude and severity of the hazard would be highly dependent on the type of spill, location, and the extent to which hazardous materials enter the water system. Hazardous materials can be flammable, radioactive, infectious, corrosive, toxic/poisonous, or otherwise reactive. Heavy rains or winds could spread hazardous materials over a larger geographical area and create challenging cleanup conditions. Hazardous materials are used in virtually every manufacturing operation by retailers, service industries, and homeowners in the City of Chula Vista. Operations known to handle hazardous materials in the City include gas stations, dry cleaners, medical facilities, commercial/retail businesses, and ro adway and railway transportation. Most hazardous materials operations are small-scale and pose a minimal risk; however, commercial transportation of hazardous materials via roadway or railway would potentially have significant impacts on the City during an incident, given the volumes of hazardous materials being transported. 2.7.2. Transportation of Hazardous Materials Transportation of hazardous materials/wastes is regulated by the California Code of Regulations Title 26. The US Department of Transportation (DOT) is the primary regulatory authority for the interstate transport of hazardous materials. The DOT establishes regulations for safe handling procedures (i.e., packaging, marking, labeling, and routing). Criteria also exist regarding personnel qualifications and training, inspection requirements, and equipment specifications. The California Highway Patrol (CHP) enforces regulations related to the intrastate transport of hazardous materials and hazardous wastes. The CHP and the California Department of Transportation (Caltrans) enforce federal and state regulations and respond to hazardous materials transportation emergencies. 2.7.3. Hazardous Materials Sites The State Water Resources Control Board (SWRCB) maintains a data management system called GeoTracker. Sites identified by GeoTracker are sites that impact or have the potential to impact water quality in jurisdictions statewide. These sites are required for cleanups, such as leaking underground storage tank (LUST) sites, Department of Defense sites, and cleanup program sites. GeoTracker also contains records for various unregulated projects as well as permitted facilities, including irrigated lands, oil and gas production, operating permitted underground storage tanks, and land disposal sites. A search of federal, state, and local databases identified numerous known and potentially contaminated sites within and immediately adjacent to Chula Vista. Known and potentially contaminated sites in Chula Vista are primarily associated with unauthorized releases of oil and hazardous substances (e.g., LUSTs); former solid and hazardous waste disposal and transfer sites; use, storage, and transport of hazardous materials; and hazardous waste generation. As identified by the SWRCB, 267 sites have been cleaned up in Chula Vista. In 2023, 27 sites were shown to have ongoing activities related to the previously known or suspected release of hazardous materials to soil and groundwater in Chula Vista. These sites and their statuses are identified in Figure 18. Page 115 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 51 Table 7 and Figure 18. In addition, EnviroStor is the Department of Toxic Substances Control's data management system for tracking cleanup, permitting, enforcement, and investigation efforts at hazardous waste facilities and sites with known contamination or sites where there may be reasons to investigate further. Of the 62 sites identified since 1990, 6 are active. These sites and their statuses are identified in Figure 18. Table 7 and Figure 18.

Siting Hazardous Waste Facilities Products as diverse as gasoline, paint, solvents, film-processing chemicals, household cleaning products, refrigerants, and radioactive substances are categorized as hazardous materials. After use, or processing, hazardous materials that remain are considered hazardous waste. Nearly all industry and businesses in Chula Vista generate some amount of hazardous waste. Hazardous waste is of concern in light of potential adverse public health and safety and environmental impacts that can result from the improper handling and disposal of such materials. Therefore, the appropriate siting of hazardous waste storage, collection, treatment, disposal and transfer facilities is important. Also important is the siting of such facilities in relatively close proximity to generation sources in order to facilitate proper and efficient disposal of hazardous waste and to reduce the transport of hazardous waste within the City. State law requires the mapping of “general areas” within which hazardous waste facilities might be established. Proposed hazardous waste facilities will be considered only if they are within the industrial Page 117 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 53 zoned general areas and meet specific siting, design, and operating criteria as established by the Chula Vista Zoning Code, and pursuant to siting criteria guidelines established by the City. 2.7.3.2. Siting and Managing Facilities The use, storage, and handling of hazardous materials and waste within Chula Vista are rigorously controlled by federal, state, and local regulations. The City uses a variety of tools to regulate facilities that use, store, and handle hazardous materials and waste in order to ensure compatibility with existing and planned surrounding land uses. The primary tools utilized by the City are zoning regulatio ns, environmental review of proposed developments in accordance with the California Environmental Quality Act, and the issuance of business licenses. As development and redevelopment in Chula Vista continue, the potential exists for facilities that use, store, and handle hazardous materials and waste to be sited in locations where such activities may be incompatible with existing and planned surrounding land uses. Through the use of appropriate tools, the City will ensure that facilities using, storing, and handling hazardous materials and waste will be appropriately sited and that the operation of such facilities will be regulated such that significant adverse effects to surrounding land uses will be avoided.

Household Hazardous Waste Program Chula Vista's household hazardous waste (HHW) program, designed to provide a means to safely collect , recycle, treat, and dispose of HHW, was implemented in 1997. Public education and awareness programs, including programs for school-aged children, support the recycling program and contribute to high participation rates. HHW includes used motor oil; latex and oil-based paints; used antifreeze; cleaning products; aerosol containers; dry cell and automotive batteries; pesticides and garden chemicals; and solvents. HHW generated by Chula Vista residents cannot be disposed of at the local and regional landfills serving the City and is, therefore, handled separately from non-hazardous solid waste. Chula Vista's current HHW program includes a temporary storage facility located at the City's John Lippitt Public Works Center on Maxwell Road. This facility was designed as a regional facility to accommodate waste from the South Bay area, including areas outside the City limits. The majority of the HHW collected at the City's facility is reused or recycled and thus diverted from landfill disposal. In addition to the City's HHW facility, the City provides free used motor oil and oil filter recycling through its hazardous waste collection. The City-has also advertised a pharmaceutical waste disposal sites, with location at the police department and various pharmacies. Source reduction, a form of diversion, is promoted through public education on alternatives to toxic products. In the absence of convenient and affordable HHW collection facilities and sufficient public education, the extent of improper HHW disposal would likely be great. The adverse impacts of improper HHW disposal to the environment and to public health and safety warrant significant efforts to facilitate proper disposal. Public education on alternatives to toxic products can yield a reduction of HHW sources and, in turn, a reduction in HHW generation; therefore, such efforts are also warranted. 2.8. Emergency Planning/Response Emergency planning and disaster response are key components in addressing the City's vulnerability to natural and human-caused hazards. A well-developed emergency planning strategy ensures that, in the event of a significant hazard event, the City of Chula Vista is prepared to efficiently respond and maintain the safety and well-being of its residents, buildings, infrastructure, and critical facilities. 2.8.1. Emergency Operations Plan The City of Chula Vista Emergency Operations Plan (EOP) was developed in accordance with following recommended guidance from the Federal Emergency Management Agency’s (FEMA) Comprehensive Preparedness Guide 101 Version 2.0. The EOP addresses the emergency response functions of local government departments, public officials, and other public and private organizations during emergencies/disasters. The plan was developed through a collaborative effort of City departments, including public safety agencies such as fire, law enforcement, and public works. These organizations play a vital role in responding to emergencies. The EOP applies to all persons participating in protection, prevention, mitigation, preparedness, response, and recovery efforts within the City. Furthermore, all stakeholders are encouraged to maintain their own procedures and actively participate in the training, exercises, and maintenance needed to support this plan. Page 120 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 56 The City of Chula Vista EOP is based on the County of San Diego Operational Area Emergency Operations Plan (OA EOP). It is designed to meet the needs of the City with respect to organizational structure and identified hazards. 2.8.2. Emergency Preparedness Program State regulations establish the Standardized Emergency Management System (SEMS). The system includes requirements for incident command systems; multi-agency coordination systems; mutual aid agreements; and the “operational area” concept. As an agency (municipality) with emergency response capability within the state, Chula Vista is required to use the SEMS system. Chula Vista provides for the preparation and execution of plans for the protection of persons and property within the City in the event of an emergency (Chula Vista Municipal Code, Chapter 2.14, Emergency Organization Department). The code requires coordination of the emergency functions of the City with other public agencies, corporations, and organizations. Federal law (Disaster Management Act 2000) requires that, in order to remain eligible for post-disaster FEMA funding, every jurisdiction in the United States must have an approved Hazard Mitigation Plan (HAZMIT plan) to address the management of, and response to, emergency situations. In addition, to be eligible for pre-disaster FEMA funding for use in hazard mitigation, each jurisdiction's approved HAZMIT plan must include the planned uses of those funds. The County of San Diego adopted its MJHMP in 2023, which included the City of Chula Vista. The plan was submitted to FEMA for approval in compliance with federal law. General Plan policies and standards tie new development and redevelopment to the provision of adequate public facilities and services, including police and fire protection. Due to the rolling terrain and varied topography, some new developments have winding streets and irregular layouts instead of the grid pattern found in older, traditional neighborhoods. Some design characteristics, such as narrow street widths, aim to create walkable communities, serve to establish an overall neighborly atmosphere, and tend to reduce traffic speeds. In mixed-use neighborhoods, density increases may result in taller buildings. The evolving urban form and the cumulative increase in development will affect emergency service response times as well as the equipment, facilities, and personnel needed for fire and police services. Crime Prevention Through Environmental Design (CPTED) is a method of incorporating design techniques into projects to help reduce the potential for crime. CPTED is used in the development of parks; residential and commercial projects; schools; transit stations; and parking lots to reduce the number of calls for service. The reduced call volume may favorably impact response times. CPTED includes the use of four primary strategies: • Providing natural access control into areas; • Improving natural surveillance (i.e., increasing “eyes on the street”); • Maintaining and managing a property to reduce crime and disorder; and • Using territorial reinforcement to distinguish private space from public space. 2.8.2.1. Emergency Response Program Page 121 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 57 A Citywide emergency response program provides the framework for responding to any type of emergency or disaster that might occur in Chula Vista. Accomplishing efficient emergency response involves coordination with other agencies regarding disaster preparedness; preparation and regular updates of the emergency operations plan; education of residents and businesses about the plan and about evacuation routes; and periodic training of City staff and other emergency response staff to effectively implement the plan. 2.8.2.2. Post-Emergency Response In the event of disasters and emergencies, a swift and efficient response minimizes injuries, casualties, and property damage. Planning post-disaster operations ensures the safety, health, and welfare of residents by allowing critical operations to continue as expeditiously and efficiently as possible following a catastrophic event. The post-disaster analysis will help the City improve safety plans and responses. 2.8.2.3. Exposure Control Plan Chula Vista Fire Department is updating the 2023 Exposure Control plan, which complies with Title 8, California Code of Regulations, Section 5193: Bloodborne Pathogens; Section 5199: Aerosol Transmissible Disease; Cal OSHA Tuberculosis Control Enforcement Guidelines and any such subsequent code or regulations aimed at reducing occupational exposure to potentially communicable pathogens. This plan: • Outlines and summarizes the requirements of the cited standards. • Evaluates routine tasks and procedures in the workplace that involves exposure to bloodborne, airborne and OPIM, identifies workers performing such tasks and uses a variety of methods to reduce risks. • Establishes field guidelines for pre-hospital care personnel, outline engineering and work practice controls, personal protective equipment, housekeeping procedures, and post-exposure evaluations to comply with the standard and communicate hazards to applicable personnel and assist in minimizing the risk of being exposed, contracting and/or spreading communicable disease. • Establishes guidelines for the management of fire department personnel, who in the line of duty, may be exposed to or contract a communicable disease. • Informs emergency responders of the risks of occupational exposure to blood/airborne pathogens and aerosol-transmissible diseases and how to reduce those risks. 2.8.3. Public Safety Services In the City of Chula Vista, fire protection and emergency medical services are provided by the Chula Vista Fire Department, and law enforcement services are provided by the Chula Vista Police Department. Fire stations are dispersed throughout the City, while police facilities are centered in headquarters in downtown Chula Vista. The current Fire Station Master Plan calls for 11 fire stations. The number and location of future fire stations, along with how they are equipped, may change. The City is currently developing the Bayfront property, which will call for the development of an additional fire station (number 12). Page 122 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 58 To maintain a high level of dependable, competent fire protection and emergency medical services for the City, several strategies will continue to be employed. The City will continue to use a growth-related service standard to help determine if public safety is adequately protected. Fire Department staffing and equipment will continue to be expanded, as needed, to meet the service standard and to minimize hazards to the firefighters and public, in conformance with changes to the updated Fire Station Master Plan. The Fire Department will continue to enhance its capabilities and staffing through mutual aid agreements with fire departments in the surrounding communities. Similar strategies also facilitate the provision of law enforcement services that meet the City's needs. The department will continue to monitor calls for service, analyze crime statistics and resident survey data, and make changes in staffing and patrols to reflect the growing community's needs. Effective fire protection and emergency medical and law enforcement services require two-way relationships with the community. Staff must understand the unique needs and condit ions in the community and the community must lend support to the various programs and efforts of the Police Department and Fire Department. The City encourages active participation by Fire and Police Departments in all facets of community life, including i nvolvement in area business and senior/youth activities. 2.8.3.1. Keeping Pace with Growth The City of Chula Vista has experienced significant residential growth over the last decade. The majority of new growth has occurred in the east, where continued relatively high growth is expected in the coming years, along with density increases in the west. Fire protection, emergency medical services, and police services will need to expand to match the demand brought on by this anticipated growth. While fire stations are located throughout the City, the Police Department maintains one police headquarters, located in the western portion of the City. If appropriate, the department could establish satellite storefront offices to provide a presence in other neighborhoods. 2.8.4. Evacuation Routes In the event of a significant emergency, clear routes are needed to ensure that emergency responders and supplies can be transported and that community members can be evacuated. Evacuation efforts depend on the severity and type of hazard incident that is occurring. In some cases, people may have a day or two to prepare, while other situations might call for an immediate evacuation. Evacuation routes include major roadways and thoroughfares intended to transport people from areas impacted by hazardous events to areas of safety. There may be occasions when a limited-scale evacuation is the appropriate response to an emergency situation. Under these circumstances, people should be evacuated to neighborhood and community schools, hospitals, and public facilities, where they could receive adequate care and treatment. In the event of a major disaster, where a large part of the City may require evacuation, the following circulation routes may be used and are depicted in Figure 19: • Interstate 5; Interstate 805; State Route 54; and State Route 125 • E, H, J and L Streets; Bonita Road; Telegraph Canyon Road; Olympic Parkway • Naples, Palomar and Main Streets; Orange Avenue Page 123 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 59 • Broadway; Fourth Avenue; Hilltop Drive; Oleander Avenue; Third Avenue; Melrose Avenue; Otay Lakes Road; and Heritage Road Evacuation routes effectively include all improved (paved) roads within the City. Unpaved roads may be used in an evacuation as a last resort but should not be relied on as a primary evacuation route. Local streets typically serve as direct access for adjacent residential and commercial development and while they are not designed to accommodate high traffic volumes, they serve limited development areas and are rarely required to handle traffic flows that would exceed their capacities, even under full evacuation conditions. For the purposes of evacuation planning, the designated evacuation route street network includes roadways that are classified as collectors and above including the following: 1. Freeways/Highways 2. Major Roadways 3. Gateway Streets 4. Urban Arterials 5. Commercial Boulevard 6. Neighborhood & Local Streets (in select areas) Designated evacuation routes are the most reliable roadway facilities for the following reasons: • These roads are designed to accommodate higher volumes of traffic in-line with their classifications. • Access controls are more stringent on roads of higher classification. • Intersection controls are designed to prioritize travel on roads of higher classification. • Roadway maintenance policies prioritize roads of higher classification. Primary evacuation routes are identified in Figure 19. Note that evacuation routes shown are to gateway exit points located at or near the City boundary. In addition, SR-125 is identified as an importation evacuation route, and while it is a toll road under emergency evacuation conditions it is presumed the evacuees would be able to access the highway without penalty or fees. Evacuation route vulnerability can be expressed from several perspectives. The most direct expression of route vulnerability deals with physical features along an evacuation route that can be damaged during emergency scenarios and cause the evacuation route to be disrupted and unusable. These physical features include: • Bridges (over rivers, creeks, and other drainage features) • Bridges (creating grade separated roadways) • Low points along the route that are prone to flooding • Route locations along steep natural slopes that are prone to landslides Page 124 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 60 Figure 19: Evacuation Routes Map Page 125 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda City of Chula Vista Safety Element City of Chula Vista 61 Figure 20 depicts physical features such as bridge structures along primary evacuation routes that may impede an evacuation if damaged at the time of an emergency which require an evacuation. The Vulnerability Assessment (separate cover) summarizes all of the critical facilities throughout. Evacuation route vulnerability can also be expressed in terms of vulnerability to residents where development areas are isolated and/or areas that have access to only one evacuation route. These areas are a concern and require additional advanced planning to address emergency scenarios where an evacuation is needed, and the single evacuation route may be blocked or damaged and cannot be used. Also shown in Figure 20 are those residential development areas (neighborhoods) that have only one access point to a primary evacuation route. These neighborhoods were identified after a thorough review of various City-wide maps and aerial photographs and include residential developments that may be access constrained during an evacuation. If a neighborhood takes direct access to another roadway and that roadway funnels to more than one designated evacuation route, it would not be considered vulnerable. Similarly, if a neighborhood does take direct access to a designated evacuation route with only one way in and out, this would be considered a vulnerable neighborhood. In an evacuation scenario, these neighborhoods could be exposed to an increased risk due to the lack of multiple egress opportunities and should be given earlier evacuation consideration.

Background Chula Vista (City) is currently undergoing an update to the Safety Element of the City’s General Plan as required by California Government Code Section 65302 to address the need to protect citizens from risks associated with natural and human-caused hazards. In parallel with the Safety Element, a Vulnerability Assessment is required to satisfy California Senate Bill (SB) 379 to identify risks climate changes poses to the local jurisdiction and the geographic areas at risk from climate change. The Vulnerability Assessment identifies specific natural hazards related to climate change and evaluates the City’s vulnerabilities accordingly. The Vulnerability Assessment considers physical threats to critical facilities within the City as well as physical threats to residential and non-residential structures. The vulnerability findings will then inform adaptation and resilience goals, policies, objectives, and implementation measures in the Safety Element Update. It should be noted that a Vulnerability Assessment was conducted by San Diego County as part of the Multi-Jurisdictional Hazard Mitigation Plan (MJHMP) and is included in the Safety Element for reference. Hazards that may require an evacuation declaration include wildfires, floods, hazardous materials exposure, geologic hazards, and seismic hazards. This Evacuation Routes Assessment address the evacuation planning for potential emergency scenarios. 1.2. Legislative Overview Under Assembly Bill (AB) 747 the City’s Safety Element needs to address evacuation planning for any emergency scenarios that would warrant an evacuation of populations within the affected areas. The evacuation planning is a component of the Safety Element (SE)). This requirement became effective as of January 1, 2022 and is required for the development of a new or updated SE. In addition, Senate Bill (SB) 99 also addresses local Safety Elements and emergency evacuation routes. This legislation requires the City to identify residential developments in hazard areas that do not have at least two emergency evacuation routes. AB 1409 includes additional requirements for the Safety Element be periodically reviewed and updated. It also requires that the SE include evacuation locations in the evacuation route planning. This Evacuation Routes Assessment report includes a capacity analysis that identifies evacuation routes and their capacity, safety, and viability under a range of emergency scenarios applicable to the local jurisdiction. This report contains important information that will serve as a resource to the Evacuation Coordinator, Emergency Manager, and emergency management support personnel to more quickly assess and plan mitigative actions for local hazard scenarios that may lead to the eventual need to order an emergency evacuation of all or a portion of populations within the City.

Designated Evacuation Zones Emergency evacuation zones for the City of Chula Vista have been developed at the County level as part of the San Diego County Zonehaven EVAC Evacuation Pre-Plan modeling program. These zones have been developed through close coordination with City staff and the Chula Vista Fire Department. Zonehaven creates online data driven smart zones that are reviewed, adjusted, and approved by local law, fire, and city staff. Zonehaven EVAC is a web-based application for first-responders to add evacuation pre-plan data and make operational decisions on changing the status of a zone during an ongoing incident. For the purposes of this evacuation assessment, multiple Zonehaven zones were aggregated into designated evacuation zones based on logical boundaries (typically following roadways) and similar access to evacuation routes for each of the hazard scenarios that have been considered. Only areas within the City that are considered to be at risk for these hazard scenarios are shown. Zonehaven maps and corresponding list of zones are included in Attachment A. As shown in Exhibit 2-1, the designated evacuation zones were categorized into two types, Fire Evacuation Zones (FEZ) and Dam Inundation Zones (DIZ). Additional assessment for these hazard scenarios is provided in Chapter 4.0. Exhibit 2-1 Evacuation Zones Page 144 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Evacuation Route Assessment 2-5 February 2024 Evacuation Route Capacity and Viability Study CITY OF CHULA VISTA 2.2. Evacuation Reception Centers Dependent upon the nature of a disaster, evacuees may have the option to evacuate to an evacuation reception center located in the immediate vicinity of the disaster. Chula Vista has pre-identified shelters throughout the City that have been vetted by the Red-Cross and can be used as long as individuals have been directed there by first responders and the shelter has not been damaged by a disaster. Dependent on the incident, one or more of these sites could be activated as a temporary evacuation point or an overnight shelter. City staff in coordination with the Red Cross would make the determination to activate as events unfold. These locations are identified in Table 2-1 and shown in Exhibit 2-2.

Evacuation Route Vulnerability Assessment Evacuation route vulnerability can be expressed from several perspectives. The most direct expression of route vulnerability deals with physical features along an evacuation route that can be damaged during emergency scenarios and cause the evacuation route to be disrupted and unusable. These physical features include:  Bridges (over rivers, creeks, and other drainage features)  Bridges (creating grade separated roadways)  Low points along the route that are prone to flooding  Route locations along steep natural slopes that are prone to landslides Exhibit 2-2 depicts physical features such as bridge structures along primary evacuation routes that may impede an evacuation if damaged at the time of an emergency which require an evacuation. The Vulnerability Assessment (separate cover) summarizes all of the critical facilities throughout. Table 2-2 below shows all of the bridges throughout the City, including those crossing the Ballona Creek and the Metro E (Expo) Line.

These areas are a concern and require additional advanced planning to address emergency scenarios where an evacuation is needed, and the single evacuation route may be blocked or damaged and cannot be used. Shown in Exhibit 2-3 and summarized in Table 2-3, are those residential development areas (neighborhoods) that have only one access point to a primary evacuation route. These neighborhoods were identified after a thorough review of various City-wide maps and aerial photographs and include residential developments that may be access constrained during an evacuation. If a neighborhood takes direct access to another roadway and that roadway funnels to more than one designated evacuation route, it would not be considered vulnerable. Similarly, if a neighborhood does take direct access to a designated evacuation route with only one way in and out, this would be considered a vulnerable neighborhood. In an evacuation scenario, these neighborhoods could be exposed to an increased risk due to the lack of multiple egress opportunities and should be given earlier evacuation consideration.

Designated Evacuation Routes Evacuation routes effectively include all improved (paved) roads within the City. Unpaved roads may be used in an evacuation as a last resort but should not be relied on as a primary evacuation route. Local streets typically serve as direct access for adjacent residential and commercial development and while they are not designed to accommodate high traffic volumes, they serve limited development areas and are rarely required to handle traffic flows that would exceed their capacities, even under full evacuation conditions. For the purposes of evacuation planning, the designated evacuation route street network includes roadways that are classified as collectors and above including the following: 1. Freeways/Highways 2. Major Roadways 3. Gateway Streets 4. Urban Arterials 5. Commercial Boulevard 6. Neighborhood & Local Streets (in select areas) Designated evacuation routes are the most reliable roadway facilities for the following reasons:  These roads are designed to accommodate higher volumes of traffic in-line with their classifications.  Access controls are more stringent on roads of higher classification.  Intersection controls are designed to prioritize travel on roads of higher classification.  Roadway maintenance policies prioritize roads of higher classification. Primary evacuation routes are identified in Exhibit 2-4. Note that evacuation routes shown are to gateway exit points located at or near the City boundary (refer Section 2.5). In addition, SR-125 is identified as a importation evacuation route, and while it is a toll road under emergency evacuation conditions it is presumed the evacuees would be able to access the highway without penalty or fees. Page 151 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Evacuation Route Assessment 2-12 February 2024 Evacuation Route Capacity and Viability Study CITY OF CHULA VISTA Exhibit 2-4: Primary Evacuation Routes 2.5. Evacuation Route Capacity While the City’s Circulation Element roadways are designed to serve two-way traffic, the designated of evacuation routes are assumed to use only one direction of travel in the outbound direction away from the hazard. Once the evacuation order has been made, the inbound direction is typically reserved for emergency management vehicles to transport personnel and equipment towards the hazard. The technical definition of the maximum capacity of a road is the maximum hourly rate at which vehicles can reasonably be expected to traverse a point during a given time period under prevailing roadway, traffic and control (free-flow) conditions. The capacity of an evacuation route considers the following factors:  Design characteristics of the roadway (i.e., lane width, shoulder width, horizontal and vertical alignment, presence of raised median)  Number of lanes in the outbound evacuation direction  Access control  Percent truck traffic Page 152 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Evacuation Route Assessment 2-13 February 2024 Evacuation Route Capacity and Viability Study CITY OF CHULA VISTA The maximum “free-flow” (uninterrupted flow) capacity of a roadway segment occurs at level of service (LOS) E when the vehicle speed and vehicle spacing is at its optimum level. Under the free-flow condition, the traffic demand is fully serviced, and the service volume increases as the traffic volume and density increase, until the service volume reaches the maximum LOS E capacity for the roadway segment. As traffic volumes and the resulting vehicle density increase beyond this "critical" value, the rate at which traffic can be serviced quickly drops below the maximum capacity. Therefore, to realistically represent traffic handling capacity during congested forced flow conditions (such as during an evacuation) it is necessary to apply a capacity reduction factor. A capacity reduction factor of 0.9 (10% reduction) has been applied based upon studies that identified a fall‐off in the maximum service flow rate (e.g., maximum capacity) when congestion occurs at “choke points” on a freeway segment. The estimated hourly vehicle capacities under forced flow evacuation conditions are summarized in Table 2-4 for each of the five designated evacuation route classifications. Table 2-4: Hourly Roadway Evacuation Capacity Classification No. Lanes (per direction) Capacity/Lane (vphpl) Reduction Factor Total Capacity (veh. in outbound direction) Diminished Capacity (1) (veh. per direction) Freeway 5 1,900 0.9 8,550 5,990 Prime Arterial 3 1,900 0.9 5,130 3,590 Major Street 3 1,900 0.9 5,130 3,590 Major Street 2 1,900 0.9 3,420 2,390 Gateway Street 2 1,900 0.9 3,420 2,390 Urban Arterial 2 1,900 0.9 3,420 2,390 Commercial Boulevard 2 1,900 0.9 3,420 2,390 Class I Collector 1 1,900 0.9 1,710 1,200 Downtown Promenade 1 1,900 0.9 1,710 1,200 Local Street 1 1,900 0.9 1,710 1,200 vphpl = Vehicles per Hour per Lane (1) Assumes 30% of the available capacity will be consumed by ambient/background (non-evacuation) traffic. It is important to note that the hourly evacuation capacity estimates shown in Table 2-3 may not be fully available to evacuating traffic during the early stages of an evacuation unless strict perimeter traffic control/access has been established before the evacuation order has been given. Depending on the time of day, conditions without positive perimeter traffic control could result in background (non-evacuation) traffic consuming between 25% and 30% of the available capacity during midday and non-peak periods. Peak period background traffic on some higher classification roadways (including those that access freeway interchanges) could represent between 70% and 100% of the available capacity. If an evacuation occurs during peak periods, perimeter traffic control will be more crucial and certain evacuation routes may not be available for use. Conversely, during late evening and early morning periods, available roadway capacity on non-freeway routes would be greater than 90% of the maximum capacity. At grade intersection controls at locations where two designated evacuation routes merge are also an important consideration during an evacuation. The approaches to at-grade intersections are where flow Page 153 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Evacuation Route Assessment 2-14 February 2024 Evacuation Route Capacity and Viability Study CITY OF CHULA VISTA can be “interrupted” by a control device or by turning or crossing traffic at the intersection. Due to the differences in the flow conditions at intersections, separate estimates of capacity must be made for these locations. In many instances, the approach to the intersection is widened through the addition of one or more lanes (turn bays), to compensate for the lower capacity of the approach caused by the interruption of traffic flow due to the intersection control device. Minor intersections are typically controlled by “stop” signs on the minor street approach(es) or at all intersection approaches if the streets serve similar traffic volumes. Arterial street intersections are typically controlled by traffic signals and the amount of green signal time is assigned to the intersection approaches based on the relative traffic volumes. During an evacuation, at‐grade intersections will likely become the first bottleneck locations once the evacuation is fully underway. During these conditions where traffic flows are concentrated in one direction and normal opposing traffic turning conflicts do not require signal intervention, traffic signals will not be able to efficiently manage the unique traffic demand pattern. This anticipated condition will result in the need to allocate right-of-way time to the respective competing traffic flows by imposing some form of proactive control. During evacuation conditions, control at the most critical intersections will often be provided by designated traffic control crews. In these cases, manual traffic control would supersede the normal stop sign or traffic signal control devices. 2.6. Distance & Travel Time to Evacuation Gateways As part of the evacuation route assessment, the most direct evacuation routing from the evacuation zones shown in Exhibit 2-1 to the closest primary evacuation gateways exiting the City was identified. City evacuation route gateways include the following:  Primary Gateways: o Gateway A – I-5 (North) o Gateway B – I-805 (North) o Gateway C – SR-125 (North)  Secondary Gateways: o Gateway D – I-5 (South) o Gateway E – I-805 (South) o Gateway F – SR-125 (South) The gateways have been separated into two categories: Primary Gateways (A,B & C) and Secondary Gateways (D, E, & F). While Secondary Gateways may be the closest for residents located in the southern parts of the City, most destinations are likely to be to the north, not the south. It should be noted that not all evacuation zones were assigned to each Gateway since individual gateways may not be a convenient or logical exit point for all zones. A centroid was placed at logical cross-streets approximately in the center of each zone (or sub-zone) as shown in Exhibit 2-5. Recommended evacuation traffic routing was then assigned from the centroid to the most convenient Gateway shown above. Page 154 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Evacuation Route Assessment 2-15 February 2024 Evacuation Route Capacity and Viability Study CITY OF CHULA VISTA Exhibit 2-5: Evacuation Zone Centroids & Gateways As a measure of evacuation vulnerability, travel time to each of the primary gateways was estimated for populations within each of the evacuation zones. To estimate the travel time from the centroid to the destination Gateway, the length of individual roadway segments, posted speed limits on each segment, and traffic control devices along the route (all-way stop, side-street stop, and traffic signal) were identified for each evacuation route. Travel time for each route segment was calculated based on the travel distance and posted speed. Typical intersection delay was estimated separately and was added to the segment travel time. An average delay factor of 20 seconds was used for each signalized intersection along the evacuation route. If an evacuation route passed through an unsignalized intersection, a delay factor of 10 seconds was applied if the routing passed through a stop-controlled approach. The sum of the individual roadway segment travel times and the total intersection delay were used to estimate the total travel time. A summary of the travel time estimates for each zone to the various Gateways is included in Attachment B. It is important to note that the estimated travel time is not an estimate of evacuation time, it is simply a calculation of uncongested, free-flow travel from the centroid of the evacuation zone to the assigned Gateway. As multiple zones are evacuated over time, the cumulative evacuation traffic will approach the Page 155 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Evacuation Route Assessment 2-16 February 2024 Evacuation Route Capacity and Viability Study CITY OF CHULA VISTA roadway capacity and may eventually exceed the available capacity of an evacuation route as they get closer to the evacuation Gateways. This results in congested conditions which would reduce the travel speed, and therefore increase the travel time to a Gateway. As mentioned above, the assignment of emergency response crews at key locations to control the flow of traffic would help to significantly reduce delay times. While the free-flow travel time does not represent the evacuation time, it does provide a relative measure of the evacuation zones that would be subject to longer evacuation times. An evacuation order should consider these more remote areas and they should be prioritized in the sequencing of evacuation notifications. The timing of evacuation notifications should consider the following factors that affect evacuation time: 1. Evacuee response time to evacuation notification (i.e. time for all evacuees to receive warning and time to prepare to leave home); 2. Estimated travel time to evacuation route gateway; and 3. Estimated added delay time due to evacuation route capacity constraints. If the critical roadway segment that will have the limiting capacity during an evacuation can be identified, the approximate evacuation time can be calculated by dividing the number of evacuating vehicles using the critical roadway segment by the outbound capacity of the critical roadway segment. The critical segment could be located close to the evacuation zone in cases where the evacuation is limited to one or two zones. In cases where multiple zones are evacuated at the same time, the critical roadway link will likely be closer to the evacuation route gateway where the accumulation of evacuating traffic is the greatest. Exhibit 2-6 through Exhibit 2-15 identify the designated evacuation route from the centroid of each evacuation zone to assigned Gateways throughout the City and summarize the travel times to individual Gateways. Exhibit 2-16 and Exhibit 2-17 shows the evacuation route to the nearest Gateway for each evacuation zone for the fire hazard and dam inundation scenarios.

During these conditions traffic signals and stop sign controls will not be able to efficiently and safely manage the evacuation traffic demand pattern. In order to maintain a safe and efficient traffic flow, it will be necessary to allocate right-of-way time to the respective competing evacuation traffic flows by imposing some form of proactive control. During evacuation conditions, manual control at the most critical intersections should be provided by designated traffic control personnel. Considering the designated evacuation routing for the City’s evacuation zones and the points where major evacuating traffic flows will be merging, it is recommended that manual traffic control be considered at the locations identified in Table 3-1 and shown in Exhibit 3-1. Exhibit 3-1: Manual Traffic Control Points The need for manual traffic control at these locations will be determined by the Evacuation Coordinator and Emergency Operations Manager. Locations that should have manual traffic control established will depend on the hazard scenario being addressed and the evacuation zones that are ordered to be evacuated. In most cases, the City’s Police Department would be responsible for providing the personnel needed for the manual traffic control function.

The two emergency scenarios include a potential fire hazard scenario and a potential dam inundation scenario. The following sections present a discussion of each emergency scenario along with the identification of corresponding evacuation procedures and recommendations for facilitating the evacuation in the event of a significant emergency. 4.1. Scenario 1 – Wildfire Hazard This scenario represents a potential fire hazard approaching from the east through the San Diego National Wildlife Refuge, Proctor Valley, and the Otay Open Space Preserve burning towards the City limits. As identified in the Vulnerability Assessment, portions of the City along the easterly and southerly boundaries are identified as very high hazard zones – see Attachment C. A wildfire in any of these zones could potentially spread into the City and threaten residential structures but are unlikely to immediately impact critical facilities. As shown in Table 4-1, facilities within the fire hazard zones include the several pump stations, the Chula Vista Transit Center, and the Fresnius Medical Care (Marina Bay).

The estimated number of personal vehicles is based on vehicle ownership data prepared by County of San Diego, Health and Human Services Agency, Public Health Services, Community Health Statistics Unit (2023) for the City of Chula Vista. Table 4-2: Fire Evacuation Zone Demographics Zone Estimated Number of Residences Estimated Number of Personal Vehicles FEZ-1 1688 3,020 FEZ-2 1122 2,007 FEZ-3 3001 5,369 FEZ-4 1711 3,061 FEZ-5 2083 3,726 FEZ-6 3520 6,297 FEZ-7 3278 5,864 FEZ-8 2489 4,453 FEZ-9 1670 2,988 FEZ-10 631 1,129 FEZ-11 1293 2,313 FEZ-12 1089 1,948 FEZ-13 1317 2,356 FEZ-14 915 1,637 FEZ-15 177 317 Total 25,984 46,485 If a fire hazard were to occur in the hills and open space to the east of the City, Evacuations Zones FEZ-6, FEZ-8, and FEZ-10 through FEZ-13 would potentially experience the highest risk since they are located along the City’s eastern boundary closest to the fire hazard. Residents in each of these zones should be directed to travel west, away from the fire hazard. As shown in the travel time assessment above, the closest gateway to these zones are along SR-125 toll road (Gateway C to the north and Gateway F to the south). However, depending on the nature, origin, and direction of a potential fire hazard, these gateways may lead them closer to the hazard and evacuees in this case should be directed to continue west toward other gateways. The estimated travel time from these zones to the closest gateways ranges from 5.75 minutes to approximately 12 minutes; however, as discussed in Section 1.2.6, these travel time estimates are not equivalent to evacuation times and should only be uses as a relative comparison for individual zones. If a fire hazard were to occur in the Otay River Basin to the south of the City, Evacuations Zones FEZ-2, FEZ-4, and FEZ-6 would potentially experience the highest risk since they are located along the City’s south eastern boundary closest to the fire hazards. While the closest gateways (Gateway E and Gateway F) show relatively fast travel times, these gateways would likely lead them closer to the hazard and residents should instead be advised to travel north towards Gateway B and Gateway C. Page 174 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Evacuation Route Assessment 4-3 February 2024 Evacuation Route Capacity and Viability Study CITY OF CHULA VISTA The evacuation routes serving these hazard zones, including Proctor Valley Road/East H Street, Otay Lakes Road / Telegraph Canyon Road, and Olympic Parkway are either 4-lane or 6-lanefacilities (two to three lanes in each direction) with a one-way outbound evacuation capacity of between 2,390 and 3,590 vehicles-per-hour (vph). In total, all fire hazard evacuation zones throughout the City have an estimate of 25,984 dwelling units, or approximately 46,485 vehicles that could potentially be evacuated due to a fire hazard. However, with the multiple evacuation route options available to residents, it is unlikely that each resident would take exactly the same route. Additionally, the staggered evacuation response by evacuating residents would also spread the evacuating traffic loading on the evacuation routes over time. Therefore, the available capacity of the roadway network is estimated to be sufficient for this hazard scenario. To avoid significant congestion, incremental evacuation of these zones should be considered if advanced warning of the fire hazard permits. In addition, while SR-125 is a toll road that charges a fee to use (typically via a transponder or license plate reader), under emergency conditions it is imperative that toll fee collection be suspended until the evacuation orders are lifted. This limits the level of conflicts residents would face during an evacuation and helps to disperse evacuation traffic loading throughout the evacuation route network. 4.2. Scenario 2 – Dam Inundation This scenario represents a potential failure at the Sweetwater Main Dam and Reservoir which lies approximately 1.5 miles to the north of the City limits. A failure at the dam could potentially inundate residential neighborhoods and critical facilities shown in Table 4-3. Dam inundation maps are provided in Attachment D. A failure at the Sweetwater Main Dam would follow the Sweetwater River through the Bonita Golf Club, Sweetwater Regional Park, Chula Vista Golf Course, the Sweetwater River Park before finally reaching the San Diego Bay. Within the City limits, the homes surrounding the Chula Vista Golf Course between Bonita Road and Sweetwater Road would experience the highest threat levels. The inundation maps show that flood waters flow downhill following lower elevations toward the San Diego Bay and would reach a maximum depth of more than 18 feet on average and potentially up to 42 feet. The maps show initial floodwaters would reach the Chula Vista Golf Course within 22 minutes with a maximum flood depth of 29 feet at it’s peak (within 41 minutes). Floodwaters would continue to flow towards San Diego Bay and reach the I-805 interchange in approximately 55 minutes with the sections of SR-54 at risk of being flooded. The Flood inundation maps show that water would likely flow along the SR- 54 under reach the I-5 interchange within 1 hour and 23 minutes. This flooding would likely impact the availability of evacuation routes and could hinder the efficient evacuation in the event of an emergency scenario. Evacuation routing should follow a path to higher ground (higher elevation) away from the flood zone (i.e., south). While the nearest gateway (Gateway B) to the evacuation zones show travel times between 3.5 minutes and 8.75 minutes, this could be potentially be impacted by the flood inundation hazard and evacuees should be directed toward other gateways via alternate routes. Page 175 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Evacuation Route Assessment 4-4 February 2024 Evacuation Route Capacity and Viability Study CITY OF CHULA VISTA It should also be noted that the SR-125, I-805, and I-5 freeways are elevated roadways and are not anticipated to be significantly impacted by floodwaters. However, the SR-54 roadway is at a lower elevation and would experience the highest threat of flood as it travels parallel to the Sweetwater River.

Zone DIZ-4 should be directed to head north outside of the City limits via Sweetwater Road towards Gateway B or Gateway C (nearest) and could potentially evacuate an estimated 177 dwelling units, or 317 vehicles. Sweetwater Road is a 2-lane facility (one lane in each direction) with a one-way outbound capacity of 1,200 vehicles-per-hour (vph). Zone DIZ-5 should be directed south on Otay Lakes Road, which is a 4-lane facility (two lanes in each direction) with a one-way outbound evacuation capacity of 2,390 vehicles-per-hour-per (vph). All of Zone DIZ-5 could potentially evacuate an estimated 513 dwelling units, or 918 vehicles, however only those residents north of Allen School Lane are shown to be at risk of flooding. It should be noted that the Willow Street Bridge connecting Bonita Road and Sweetwater Road over the river, while elevated, could be potentially at risk of flooding and should not be utilized. Similarly, Bonita Road runs parallel to the river and is also at risk of flooding and should not be utilized. With the multiple evacuation route options available to residents, it is unlikely that each resident would take exactly the same route.

Licensed Healthcare Facilities, Schools, Fire Stations and Law Enforcement Facilities from SanGIS, February, 2019. Highways are from CalTans, 2018 1. This map was developed for the benefit of local emergency managers and the California Governor's Office of EmergencyServices. The information shown is approximate and should be used as a guide for emergency response and preparation. 2. The inundation map meets all applicable state and federal standards and has been prepared in consideration of potentialdownstream hazards by a licensed civil engineer. 3. The results presented herein do not reflect the structural integrity of the dam and are not a statement of the dam's safety.The analysis presented is based on a hypothetical dam failure of Sweetwater Main Dam using 2D modeling software. 4. Cross Section Values:Distance from Dam and Stationing are reckoned from the centerline of Sweetwater Main Dam along the displayed Flow Path.Distance from Dam is in miles and Stationing is in feet (Stationing 12+34 = 1,234').Initial Wave Arrival Time, 1 Foot is the time to achieve 1 foot of water depth after initiation of the dam break.Time to Peak is the time to achieve the maximum water depth after initiation of the dam break. 2:00 0 500 1,000250Feet 0 0.125 0.25Miles 4. Cross Section Values continued:Peak Inundation Depth is the maximum water depth in feet.Peak Velocity is the maximum velocity in feet per second.Peak Discharge is an estimate of the maximum flow rate integrated over the entire cross section line in cubic feet per second.Peak Water Surface Elevation is the maximum water surface elevation in feet.Location Description indicates major roads that cross, or are near, the Flow Path at that cross section. 5. The values displayed in the table for each cross section are the maximum for that parameter along each cross section line, except for theInitial Wave Arrival Time, 1 Foot and Time to Peak which are the minimum for that parameter along each cross section line. 6. For other details refer to the supporting report "Sweetwater Main Dam Inundation Technical Study" February 2019. 7. Structures are shown in the aerial photo on the maps but may not clearly display all possible structures potentially within the inundation limits. 8. Map projection: State Plane, California Zone VI, Feet, North American Datum 1983. Border Tics display these coordinate values.All elevations are referenced to North American Vertical Datum 1988.

To avoid significant congestion, incremental evacuation of these zones could be considered if advanced warning of the flood hazard due to the dam breach permits. Given the distance to Sweetwater Dam and Reservoir, Inundation maps show that initial flood waters will reach the City in just less than 25 minutes. Given the time between the dam breach and flooding effects that would impact or make evacuation routes unusable, it will be critical to develop advance warning methods that would identify a likely breach of the dam so the preemptive evacuation order could be given. One such example would be an earthquake event that causes damage to the dam but does not immediately cause a dam breach. Under some emergency scenarios such as an earthquake that does cause immediate rupture or dam breach, it may not be possible or practical to declare a vehicle-based evacuation and a shelter in place order may be more appropriate. Page 210 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Attachment 4 RESOLUTION NO. 2024-06 RESOLUTION OF THE CITY OF CHULA VISTA PLANNING COMMISSION RECOMMENDING THAT THE CHULA VISTA CITY COUNCIL ADOPT A RESOLUTION TO ESTABLISH A SAFETY ELEMENT WITHIN THE GENERAL PLAN IN COMPLIANCE WITH STATE LAW WHEREAS, Senate Bill 1035 (“SB 1035”) requires that a local jurisdiction update its Safety Element upon each revision of its Housing Element or Local Hazard Mitigation Plan. The City of Chula Vista updated its Housing Element in October 2022 and is now establishing a Safety Element in compliance with SB 1035; and WHEREAS, the City’s existing General Plan was approved in 2005 and included six elements: Land Use and Transportation, Economic Development, Housing, Public Facilities and Services, Environmental, and Growth Management; and WHEREAS, goals and policies related to issues of safety were included within the Public Facilities and Services and Environmental Elements, which covered the following: Flooding and Erosion; Seismic and Geologic Instability; Wildfire; Climate Resiliency; Crime; Health Emergencies; and Hazardous Materials; and WHEREAS, the Safety Element would consolidate and update those goals and policies into a standalone Safety Element within the General Plan; and WHEREAS, the Director of Development Services has reviewed the proposed Safety Element for compliance with the California Environmental Quality Act (“CEQA”) and determined that the Safety Element does not require a subsequent EIR or a Negative Declaration for the update to the City’s Safety Element in that substantial changes are not proposed, the circumstances to which the General Plan was adopted have not changed, and no new information of substantial importance has arisen since the prior environmental documents have been certified. Furthermore, it has been determined that the proposed consolidation of safety goals and policies is exempt from the CEQA Guidelines pursuant to Sections 15060(c)(2) and 15061(b)(3) in that the proposed amendments which are primarily limited to policy modifications and updates in compliance with Government Code Section 65302(g)1 through 9 and are not anticipated to result in a direct or reasonably foreseeable indirect physical change in the environment, nor will the proposed changes have the potential for causing significant effect on the environment; and WHEREAS, City staff recommends that the Planning Commission recommend approval the proposed establishment of a Safety Element within the General Plan to the City Council; and WHEREAS, a hearing time and place was set by the Planning Commission to consider the General Plan Amendment and notice of said hearing, together with its purpose, was given by its publication in a newspaper of general circulation in the City, at least ten (10) days prior to the hearing; and Page 211 of 229 City of Chula Vista Planning Commission March 27, 2024 Agenda Planning Commission Resolution 2024-06 March 27, 2024 Page 2 WHEREAS, after review and consideration of the Staff Report and related materials for this matter, the Planning Commission held a duly noticed public hearing to consider said General Plan amendments on March 27, 2024 at 6pm in the Council Chambers, 276 Fourth Avenue, before the Planning Commission and the hearing was thereafter closed. NOW, THEREFORE, BE IT RESOLVED by the Planning Commission hereby recommends that the City Council of the City of Chula Vista adopt the proposed General Plan amendments to the Chula Vista General Plan to establish a Safety Element. BE IT FURTHER RESOLVED THAT that the Planning Commission hereby recommends that the City Council of the City of Chula Vista find that the proposed Project is in compliance with CEQA and has determined that the Safety Element does not require a subsequent EIR or a Negative Declaration for the update to the City’s Safety Element in that substantial changes are not proposed, the circumstances to which the General Plan was adopted have not changed, and no new information of substantial importance has arisen since the prior environmental documents have been certified.
