Executive Summary/Explanation & Analysis SANDAG is the Metropolitan Planning Organization for the San Diego region and plays a key role in the regional coordination of a variety of projects. The San Diego region has 19 jurisdictions, 10 of which are located in the coastal zone and collectively manage approximately 70 miles of coastline that can be accessed via transit, highways, roadways, and bicycle and pedestrian facilities. The Buena Vista Lagoon is currently a large freshwater feature that serves as a landmark and de facto boundary between the Cities of Oceanside and Carlsbad. It contains coastal wetland habitat used by a number of wildlife species. A majority of the lagoon is owned by the California Department of Fish & Wildlife and designated as a State Ecological Reserve. The lagoon’s four basins, divided by Carlsbad Boulevard, the railroad tracks, and the I-5 Freeway, are vegetated around the perimeter with open water in the middle. Pre-1940s, the lagoon was in a dynamic equilibrium between a tidally influenced saltwater system during dry conditions and a river-influenced freshwater system during wet weather conditions. The combination of these inputs resulted in the creation of extensive salt flat habitats covering approximately 75 percent of the lagoon. Historical records indicate that an additional 23 percent of lagoon area was composed of salt marsh habitat. In 1940, the lagoon was converted to a predominantly freshwater system as a result of the installation of a weir across the lagoon outlet that precluded saltwater from entering. The existing weir, built in 1972, spans approximately 50 feet, and maintains a minimum water level within the lagoon. Sedimentation from the watershed upstream of the lagoon has accumulated within the lagoon basins, leading to decreasing water depths and increasing nutrient levels. Additional influences from adjacent urbanization have affected water quality, including runoff June 5, 2025 Item #3 1 of 42 from adjacent roadways and development, as well as releases of sewage into the lagoon. Encroachment of nonnative vegetation into the open water basins of the lagoon has also been occurring, leading to water quality and vector issues as circulation decreased. In 1982, the cities of Carlsbad, Oceanside, and Vista created the Buena Vista Lagoon Joint Powers Committee. The initial focus of the Committee was grading and sedimentation control. In 2001, the Committee updated its focus to the development of a long-term management plan with the lagoon’s major property owner, the California Department of Fish & Wildlife (CDFW). In 2004, a feasibility study was conducted for a Buena Vista Lagoon enhancement project. This study projected that between 2030 and 2050, the lagoon was expected to become a vegetated freshwater marsh or riparian woodland-meadow. This transition could reduce coastal habitat biodiversity or eliminate saltwater marsh coastal wetland functions and values, and result in decreased water circulation, leading to concerns about vectors and water quality impairments. In July 2012, SANDAG became involved in enhancement efforts for the lagoon as a component of the North Coast Corridor Public Work Plan/Transportation and Resource Enhancement Program (PWP/TREP). That document was prepared to address comprehensive, system-wide transportation and transit improvements proposed by the California Department of Transportation and SANDAG within the north San Diego coastal corridor. The PWP/TREP identifies opportunities to improve ecological health and hydrological connectivity to enhance coastal resources and habitats within the corridor, including the lagoon enhancement project. Since 2012, SANDAG has compiled studies and initiated the design of the lagoon enhancement project. On Nov. 16, 2018, the final environmental impact report on the lagoon enhancement project was presented to the SANDAG Board of Directors for certification. At the request of the City of Carlsbad, a motion was approved to delay any action on the enhancement project to allow key residents and applicable agencies to reach a consensus on the designs alternative to be pursued. On June 6, 2019, SANDAG staff met with key property owners who presented a proposal for a modified saltwater alternative with additional legal terms and conditions. On Sept. 10, 2019, the City Council received a presentation from SANDAG staff on the status of the enhancement project (Exhibit 1). At the time, SANDAG staff were analyzing the engineering, environmental and legal aspects of the proposal for the modified saltwater alternative. On May 12, 2020, the City Council adopted a resolution approving a letter of support to the SANDAG Board of Directors for selection of the modified saltwater alternative and authorizing the City Manager to negotiate a project agreement with SANDAG, the City of Oceanside, the CDFW and certain property owners (Exhibit 2). On May 22, 2020, the SANDAG Board of Directors adopted a resolution accepting the modified saltwater alternative for the project. SANDAG continues to be responsible for the overall project management and updates the Buena Vista Lagoon Joint Powers Committee, staff from the Cities of Carlsbad and Oceanside, and representative residents on a quarterly basis. The most recent meetings of the Committee were held on Feb. 27 and May 22, 2025 (Exhibit 3). June 5, 2025 Item #3 2 of 42 On May 22, 2025, Beach Preservation Commission Chair Stark submitted a memorandum for distribution to fellow Commissioners regarding the Rue Des Chateaux (North) Beach, adjacent to the outlet of the Buena Vista Lagoon (Exhibit 4). Littoral Zone Nourishment Site Characteristics and Background There are two locations near the lagoon, Oceanside and North Carlsbad, where materials dredged from the lagoon during enhancement activities may be placed, depending upon grain size, which influences suitability for beach or nearshore placement. The Oceanside placement site includes both onshore and nearshore areas. The onshore Oceanside site is approximately 0.8 mile long and located north of the lagoon outlet. This onshore site consists of typically sandy beach between Wisconsin Street and Morse Street where riprap (large boulders) has been placed to protect beachfront residential structures. The placement site is not the currently permitted site specified under the existing Oceanside Beach Fill Program. The nearshore Oceanside site is under water with a bottom characterized by sand. The North Carlsbad placement site is an onshore site extending approximately 3,000 feet from immediately south of the lagoon outlet to Oak Street. The North Carlsbad placement site is a typically sandy beach backed by residences. The character of each placement site varies by season, tide, storm damage, and periodic beach nourishment activities. Both the Oceanside and North Carlsbad locations had sand placed directly on their shorelines as part of the 2001 and 2012 Regional Beach Sand Projects. Next Steps Staff will remain in communication with SANDAG staff regarding developments on the Buena Vista Lagoon Enhancement Project. Staff will also include an agenda item for the Commission on the project at a significant milestone, and invite SANDAG staff to the meeting to provide an updated presentation. Exhibits 1.

Recommended Action Receive a presentation from the San Diego Association of Governments (SAN DAG) regarding the Buena Vista Lagoon Enhancement Project (Project). Executive Summary Over many decades, the health of the Buena Vista lagoon has declined due to natural and anthropogenic impacts. Numerous federal, state and local agencies and organizations have cooperated in the past ir, an effort to gain consensus on a solution. In 2012, SAN DAG agreed to serve as the new lead agency for the environmental review process for the Project. The Project includes completing engineering studies and preparing an environmental impact report (EIR) to analyze possible approaches to the enhancement of the lagoon. A minimum of four alternatives were proposed for evaluation: three enhancement alternatives -freshwater, saltwater and a saltwater/freshwater hybrid regime; and a no project alternative. Through the EIR process, SAN DAG engaged federal and state agencies, the cities of Carlsbad and Oceanside, and the public in considering alternatives and potential solutions. SAN DAG will provide the city council with an overview of the project and an update on the EIR process and selection of a preferred alternative. Discussion Buena Vista Lagoon spans the boundary between the cities of Carlsbad and Oceanside. The lagoon encompasses approximately 220 acres, extending to the coastline from east of Interstate 5. The lagoon is ·downstream of the Buena Vista Creek, which drains approximately 20 square miles of the Buena Vista watershed into the Pacific Ocean. It is a freshwater lagoon, protected from almost all tidal influence by a beach berm and a physical barrier, known as a weir, located at the mouth of the lagoon. Several individuals and agencies own portions of the lagoon, including the California Department of Fish and Wildlife (CDFW), whose lands are designated as a state ecological reserve. The lagoon is surrounded by urban development and traversed by multiple transportation corridors, all of which have contributed to a continual degradation of the lagoon over time. The Project would enhance the lagoon to improve both its ecological and recreational values through implementation of one of a range of alternatives. Sept. 11, 2019 Item #11 Page 1 of 4 Exhibit 1 June 5, 2025 Item #3 4 of 42 In 2012, SAN DAG agreed to serve as the lead agency under the California Environmental Quality Act (CEQA) for the environmental review of the Project. In 2017, SANDAG prepared an EIR that equally analyzed saltwater, freshwater, saltwater/freshwater hybrid and no project alternatives; along with preliminary design for each alternative. The final EIR finds that each of the alternatives are superior to a no project alternative. While almost all stakeholders agree that something needs to be done, the various adjacent property owners, stakeholders and regulatory agencies have different views on the long-term vision for the lagoon. Some would like to see an open freshwater system, others look at the lagoon as a great opportunity to increase tidal flow and promote coastal saltmarsh habitat. The Project location and existing habitat distribution map is presented in Exhibit 1. SAN DAG staff has recommended the saltwater alternative as the preferred alternative because it wo~ld provide the largest benefits to improve water quality, reduce mosquito habitat and vector-borne mosquito diseases, reduce flooding, and support a healthier environment for native species. The federal and state agencies have indicated that the saltwater alternative is the only alternative that could serve as mitigation for future transportation projects. SAN DAG has also received significant comments from certain stakeholders requesting that the freshwater alternative be designated as the preferred alternative instead. During the Nov. 16, 2018 SAN DAG Board of Directors meeting and at the request of the Carlsbad City Council, a motion was approved to delay any action on the project for six months to allow residents to reach a consensus on the enhancement efforts. On June 6, 2019, SAN DAG staff met with the key property owners who presented a proposal for a modified saltwater alternative with additional legal terms and conditions. SAN DAG staff is in the process of analyzing the engineering, environmental and legal aspects of this proposal. SAN DAG staff anticipates returning to the SAN DAG Board of Directors with the analysis and a recommendation for their consideration in late fall/early winter 2019. SAN DAG has committed $800,000 in TransNet funds for the Buena Vista Lagoon environmental review process. Additionally, the cities of Oceanside and Carlsbad each contributed $100,000 toward the study. A budget amendment would be required to continue with project implementation to advance engineering design and obtain regulatory permits. Funding for implementation of a potential enhancement project will be explored after completion of the EIR process and selection of a preferred alternative by SAN DAG. According to SANDAG, advancement of the saltwater alternative to 65% design and obtaining all state and federal regulatory permits is estimated to cost approximately $4 million and would take approximately two to three years to complete, after funding is secured. Fiscal Analysis This item has no fiscal impact since it is an informational presentation. Next Steps SAN DAG Board of Directors will receive a presentation from their staff with an an engineering, environmental and legal aspects of a modified saltwater alternative and staff recommendation in late fall/early winter 2019. Sept. 11, 2019 Item #11 Page 2 of 4 Exhibit 1 June 5, 2025 Item #3 5 of 42 SAN DAG is expected to move forward with design of a preferred alternative for the Project, if and when the SAN DAG Board of Directors certifies the final EIR and approves the alternative as the project. This would include seeking necessary federal and state regulatory permits and funding for project delivery. Environmental Evaluation (CEQA) Receiving a presentation does not qualify as a "project" per State CEQA Guidelines Section 15378, as it does not result in a direct or reasonably foreseeable indirect physical change in the environment.

Executive Summary SAN DAG has completed the final environmental impact report for the Buena Vista Lagoon Enhancement Project. SAN DAG representatives will present an overview of the project alternatives they considered (freshwater, saltwater, hybrid, modified saltwater and no project), the reasons for identifying the modified saltwater alternative as the proposed project, and the recommended approach and next steps to advance the project. A resolution is presented to approve a letter of support for SANDAG's selection of the modified saltwater alternative and to authorize the negotiation of a project agreement for future approval by the City Council. Discussion The Buena Vista Lagoon is a freshwater lagoon located along Carlsbad's northern city limit. The lagoon encompasses about 220 acres, extending from the coastline to just east of Interstate 5. The lagoon is in a state of biological decline, and over the past decade numerous federal, state, and local agencies and organizations have tried to reach consensus on how to reverse this decline through a large-scale enhancement effort. The Buena Vista Lagoon Enhancement Project includes engineering studies and the preparation of an Environmental Impact Report to analyze possible approaches to the enhancement of the lagoon. In November 2018, the project's final environmental impact report was presented to the SAN DAG Board of Directors for certification. At the request of the City of Carlsbad, the Board approved a motion to delay any action on the project for six months to allow residents to reach May 12, 2020 Item #5 Page 1 of 5 Exhibit 2 June 5, 2025 Item #3 10 of 42 a consensus on the enhancement efforts. The proposed modified saltwater alternative represents the result of this effort. SANDAG has completed its engineering and environmental analyses, which can be found on the agency's website along with the final environmental impact report at keepsandiegomoving.com/buena_vista_lagoon_intro.aspx. On May 22, 2020, the SAN DAG Board of Directors is expected to consider approving the modified saltwater alternative as the proposed project and to certify the final environmental impact report. SAN DAG staff recommends that the board approve the alternative and the report, but with the condition that a master agreement be reached among certain property owners, the cities of Carlsbad and Oceanside, the California Department of Fish and Wildlife and SAN DAG before the final engineering work begins. This agreement would identify agreed upon terms, relinquish all prior easements and replace them with new easements prior to construction bid at no cost. Fiscal Analysis There is no direct fiscal impact to the city in receiving this report or in adopting the proposed resolution. Next Steps The SAN DAG Board of Directors will consider approving the modified saltwater alternative as the project and certifying the final environmental impact report on May 22, 2020. Upon City Council approval, staff will submit a letter of support for the modified saltwater alternative and negotiate a project agreement with SAN DAG, the City of Oceanside, the California Department of Fish and Wildlife and certain property owners for future approval by the City Council. Environmental Evaluation (CEQA) Pursuant to Public Resources Code Section 21065, this action of receiving an update on the Buena Vista Lagoon Enhancement Project does not constitute a "project" within the meaning of the California Environmental Quality Act in that it has no potential to cause either a direct physical change in the environment, or a reasonably foreseeable indirect physical change in the environment, and therefore does not require environmental review.

The proposed project will effectively reverse the ecological decline of this vital natural resource while reducing flood risks and improving water quality. The project will provide enhanced habitat for endangered species while diminishing the lagoon's suitability as a breeding grounds for mosquitos. Finally, as the result of a collaborative effort among project stakeholders, and given the project's consistency with the North Coast Corridor Public Works Plan and eligibility for use as mitigation for regional transportation infrastructure projects, the modified saltwater alternative is the best option for realizing the significant environmental benefits this project will bring to Carlsbad and the greater San Diego region. We thank you for your consideration and leadership in advancing this important project.

I am Allan Wanamaker I live at Jefferson Street, Carlsbad. I am against any salt water or mixed regime for the lagoon. I believe it should remain fresh water, as it is now. BV Lagoon is unique as a fresh water regime, supporting wildlife dependent on it. I believe major siltation will occur at the choke points if the mouth of the lagoon is opened, and constant maintenance will be required to maintain a mixed regime. I think this enhancement project is a horrendous waste of our money. Several lower cost alternatives are available, saving many millions of our dollars. Thank you for your consideration. Allan J.

ADJOURNMENT 2 June 5, 2025 Item #3 39 of 42 MEMORANDUM May 22, 2025 TO: Fellow Beach Preservation Commissioners FROM: Beach Preservation Commission Chair Lisa Stark RE: DEGRADATION OF RUE DES CHATEAUX BEACH AND PROPOSED SOLUTION Carlsbad’s Northernmost beach, Rue des Chateaux, is rapidly losing sand due to recent storm activity, causing erosion, sediment depletion and coastal retreat. This problem is seriously diminishing the public utility and enjoyment of this beach. See below photos. A large reef is developing near the slope supporting the Beach Villas, greatly limiting space for the public to access and enjoy this beach, endangering wildlife frequenting the beach, as well as creating problems for the lifeguards trying to monitor swimming and other water activities in the area. As stewards of our coastline, we must draw the City Council’s attention to the issue as soon as possible. Here are some suggestions: SANDAG and the Buena Vista Audobon Society are currently working on a project to restore the Buena Vista Lagoon that is currently in the design and permitting phase. However, they are seeking additional funds to implement the project, which we will hopefully get an update as to an execution and completion date at the June 2025 Beach Preservation Commission Meeting – the last one. Exhibit 4 June 5, 2025 Item #3 40 of 42 I am also aware of SANDAG’s RBP III, which promises to put 240,000 cubic yards of sand on the north Carlsbad beach. However, the preliminary process is only about 65% complete (per the spread sheet we asked staff to create), with no hope for any sand dump until 2027 at the earliest. I have been a Beach Commissioner for almost four years and am just now seeing some progress on replenishing sand on our beaches. I really appreciate Staff’s placing each project into a spreadsheet and regularly updating the sheet as projects progress. However, I feel that Rue de Chateaux has been somewhat ignored during the current replenishment phase. How can we express the urgency and importance of the project given the local state of this Beach? On a larger matter, and perhaps more importantly, we have all expressed concern about our efforts to retain the sand we put on our beaches every 4 years or so. We must express our interest in retaining this important resource, so it does not continue to diminish as our coast continues to evolve and erode due to sea level rise. We will now be operating under the broader category of Environmental Sustainability, but we still need to emphasize the importance of protecting our beaches and moving replenishment projects along and developing some plans to retain the sand we keep replenishing. The City Council needs to hear our concerns. To effectuate this, we could organize informational sessions/events to educate the community and try to get volunteer contributions to create a beach sustainability project. We could engage social media to request participation in the project to move it forward ASAP. We could write a letter to the interested parties showing our support to move the RBS project forward ASAP, request meetings with SANDAG and the Buena Vista Audubon Society to see how our community can begin efforts to retain the sand we lose every year. I did some research on sand retention efforts nationwide, and I personally admire Oceanside’s “Living Speed Bumps” project. It was well thought out and innovative, combining proven methods with site specific adjustments to ensure long-term effectiveness. Jaimie Timberlake explained that Oceanside looked at these 3 options: 1.Strategic Sand Retention Structures – such as installing small groins along the beach to stabilize the sand and reduce erosion. These groins would help naturally retain sand, increase beach usability and longevity. However, our City objected to this option for fear it would interfere with our beaches; Exhibit 4 June 5, 2025 Item #3 41 of 42 2.Offshore Reef – construct an artificial reef to mitigate wave energy and prevent further sand displacement. The reef would also serve as a habitat for marine species and contribute to ecological health 3.Dune restoration – plant native vegetation to create a natural barrier against erosion and enhance biodiversity, similar to what we are doing at the Ponto beach site. Oceanside has decided on a course of action to create “living speed bumps” and is moving forward. We could mimic Oceanside’s project in Carlsbad by working with coastal engineers, environmental scientists and local stakeholders to recommend a similar structural change to the Rue des Chateaux beach, and all of Carlsbad’s beaches, ensuring the design meets both environmental and community needs. This project would be smaller, so less expensive. Oceanside implemented their project in phases to minimize disruptions and assess effectiveness at each stage. We could establish a monitoring program to track the project’s impact and incorporate sustainable materials to align with environmental standards. Like Oceanside’s project, this solution will not only address the immediate sand loss but also improve coastal resilience, boost tourism, and support marine ecosystems, providing lasting benefits for our community. Let’s try to work with Oceanside to foster a better relationship between the cities! As Chair of the Carlsbad Beach Preservation Commission for the last meeting, I do not find it effective to do nothing to avoid sand depletion. Let’s at least share our concerns with our City Council and come up with some viable suggestions for a prompt solution.
