Executive Summary The Carlsbad Municipal Code 21.202.060 regulates the conversion of coastal agricultural property to urban uses. The municipal code allows the conversion of specific parcels located within the Coastal Zone only upon payment of a mitigation fee. Over time, the mitigation fees accumulate and are then made available as grants to organizations proposing coastal-focused improvement and restoration projects. The Batiquitos Lagoon Foundation has two projects that were approved in prior years and for several reasons have yet to be completed. This agenda item is to provide an overview of these two projects for the Agricultural Conversion Mitigation Fee (ACMF) Citizens Advisory Committee to consider recommendations to the City Council as applicable. Explanation & Analysis Below is a general description of two Batiquitos Lagoon Foundation projects with funding detail, followed by a more detailed discussion of each project. Batiquitos Lagoon Projects PROJECT NO PROJECT FUNDING STATUS AWARDED APPROPRIATED EXPENDED AGP 06-12 Batiquitos Lagoon Resiliency Plan $730,589 $124,995* $111,284 See below AGP 09-03 North Shore Trail $98,572 $98,572 $59,754 See below TOTALS $829,161 $223,567 $171,038 *Denotes a discrepancy with appropriation amounts for this project, as discussed below. AGRICULTURAL CONVERSION MITIGATION FEE CITIZENS ADVISORY COMMITTEE Jan. 31, 2024 Item #2 Page 1 of 153 AGP 06-12 – Lagoon Resiliency Plan The Batiquitos Lagoon Resiliency Plan project was envisioned to be a long-term plan to identify data gaps and develop climate change adaptation strategies. The project was to be completed in four phases: o Phase 1 – Scenario planning and data needs o Phase II – Data collection as needed o Phase III – Adaptation strategies o Phase IV – Final Report Original anticipated completion date 2019 The project was first approved by the ACMF Citizens Advisory Committee on Nov. 18, 2006. At the time, the Committee recommended that the City Council approve an award for the project of $780,589, of which $74,995 would be appropriated and made available to the Batiquitos Lagoon Foundation. Subsequently, on Nov. 13, 2007, the City Council approved Resolution No. 2008-050 which approved the grant award of $780,589 and appropriation of $74,995. On Nov. 29, 2016, the ACMF Committee approved another appropriation of $100,000 for AGP 06-12, followed by City Council approval on April 11, 2017, by Resolution No. 2017-061. Lastly, on Oct. 26, 2017, the ACMF Committee recommended that the total grant award for project AGP 06-12 be reduced by $50,000 to make additional funds available for other eligible projects. The City Council approved this funding reduction on Feb. 27, 2018, by Resolution No. 2018-025. It was later determined by city staff that the City Council approved reduction of $50,000 to this grant project was mistakenly reduced from the appropriation balance, and not the award balance. There has been no further ACMF Committee discussion or City Council action on this project since that time. Current status: -$111,284 expended; remaining appropriated balance of $13,711: o There is a discrepancy between award balance and appropriated balance. It was determined that the 2018 reduction in funding of $50,000 was mistakenly reduced from the appropriated funding, not the total award funding. -Phase I completed as of February 2020. -Established Water Quality Management Program: o First sampling collected January 2022. -Next steps include contracting with consulting firm for routine environmental sampling: o Expected costs $84,949, anticipated completion November 2024. o Ongoing sampling expected to cost $89,000 annually and to be completed from January 2025 – January 2030. Applicant Request: Batiquitos Lagoon Foundation is requesting that $84,949 be appropriated at this time to cover the costs of the environmental sampling through November 2024. Batiquitos Lagoon Foundation also requests that the award balance of AGP 06-12 be reduced by $35,287 and Jan. 31, 2024 Item #2 Page 2 of 153 added to project AGP 09-03, and that remaining award balance of AGP 06-12 remain reserved for the project. AGP 09-03 – North Shore Trail The Batiquitos Lagoon North Shore Trail project was envisioned to be a multi-phased project including planning and design, property acquisition, wetland restoration and invasive species removal, and trail building. The project was expected to begin in December 2009 and be fully completed in June 2012. The Batiquitos Lagoon North Shore Trail project was first approved by the ACMF Committee on June 15, 2009. At which time, the Committee recommended that the City Council approve an award for the project of $98,572, all of which would be appropriated and made available to the Batiquitos Lagoon Foundation. Subsequently on June 28, 2009, the City Council approved a grant award and appropriation of $98,572 to project AGP 09-03. There has been no further ACMF Committee discussion or City Council action since that time. Current status: - $59,754 expended; remaining appropriated balance of $38,818. -Invasive species removal and erosion control of trail are ongoing. -Efforts to acquire the property required to complete the trail segment have stalled, therefore a new trail segment is being proposed: o New trail (noted as “Trail Segment 12C” in City of Carlsbad Trails Master Plan) will connect public trail system east of I-5 with the public trail system west of I-5. CALTRANS has completed the design and plans are in the permitting process. o Batiquitos Lagoon Foundation is coordinating the implementation of a 225 ft trail that would connect the new I-5 trail and existing San Pacifico trail head. -Next steps are for Batiquitos to engage a design firm to complete a ‘shovel ready’ design for the 225 ft trail connection. The design work is expected cost $74,105 and anticipated completion is 10 months after contact execution. The total cost and timeframe for trail implementation is not known and is not part of this request. Applicant Request: Batiquitos Lagoon Foundation is requesting that the ACMF Committee consider the revised project, including an additional ACMF funding request of $35,287 for trail design. Batiquitos Lagoon Foundation proposes to reduce the award balance of project AGP 06-12 to support this request. The estimated cost and timeframe to complete the trail segment is unknown at this time. Batiquitos Lagoon Foundation is not requesting an additional ACMF fund award for that at this time, however, may request additional funds at a later date. Fiscal Analysis The ACMF program is a fully funded through mitigation fees and there is no fiscal impact on the city’s General Fund. The ACMF grant program operates on a reimbursement basis; therefore, grant recipients expend funds first and then submit reimbursement requests to the city. Funding for the projects described in this report have all been included and appropriated in the approved budget for the ACMF Fund. Should the Committee direct staff to take recommendations to the City Council to appropriate funds to the two projects discussed in this Jan. 31, 2024 Item #2 Page 3 of 153 report, there would be no fiscal impact as those funds are available in the ACMF budget and have been previously awarded. Should the Committee direct staff to take recommendations to the City Council to reduce award funding from the two projects discussed in this report, the Committee would need to provide direction to city staff as to the use of those funds. Environmental Evaluation The City Planner finds that adoption of a resolution modifying the funding for Batiquitos Lagoon Foundation ACMF-funded projects is exempt from environmental review under the California Environmental Quality Act under CEQA Guidelines section 15061(b)(3), because it can be seen with certainty that the project will have no significant negative impact on the environment.

Subject: Batiquitos Lagoon Sampling of the South Shore Area West of I-5 PURPOSE The Batiquitos Lagoon Foundation (BLF) requests environmental sampling of sediments within Batiquitos Lagoon (BL) at the site designated “the south shore area west of I-5 Freeway”. Historically, the surrounding terrestrial environment was dominated by agricultural lands that have progressively been converted to housing and commercial uses. As development expanded, stormwater capture infrastructure was expanded to collect and direct to discharge points within BL. Dedicated sediment collection on the south shore area west of I-5 Freeway using core samplers to determine the presence of legacy agriculture contamination has not been completed previously. This represents the first investigation of legacy contamination of sub-surface sediments. SCOPE OF WORK The scope of work was developed in consultation with Mr. David Hill and Dr. John Helly. Batiquitos Lagoon South Shore Area west of I-5 Freeway Miller Marine Science & Consulting, Inc. (MMSC) will collect five (5) sediment core samples from the Batiquitos Lagoon South Shore Area west of I-5 Freeway. A small area at each of the five (5) sampling stations will be cleared of vegetation by hand. MMSC will drive each core to attain either a 24-inch core sample or drive to resistance failure where the core could not penetrate the sediment any further. A new, chemically inert liner will be used in the core sampler for each station. After driving, the core will be removed from the ground and the liner pulled out. The liner ends will be capped to prevent any contamination or material loss. The liner will be labeled with the station identification corresponding to the data sheet. The liners will be kept in a vertical orientation and chilled in a custom rack through delivery to the analytical laboratory. The analytical laboratory will process the cores and collect a subsample approximately every six (6) inches from the core’s bottom achieving four (4) subsamples per core. In the event the core is less than 24 inches long, the subsampling will be revised and the core nearest the sediment surface will either be less than six (6) inches from the prior sample or no sediment surface subsample will be collected. A total of 20 samples (four subsamples per core) for laboratory analysis are planned. The laboratory’s standard turnaround time to generate testing results is currently 20 business days. In addition to the cores, surface sediments will be collected at each of the core sampling stations. A small area at each of the five (5) sampling stations will be cleared of vegetation by hand. A clean stainless-steel spoon will be inserted 5 cm into the sediment and used to scoop up sediments. The collected sediments will be placed into the laboratory provided sample jars and labeled. All jars will be placed in a cooler with ice to maintain a cool temperature until all sampling is complete. A total of 5 surface sediment samples for laboratory analysis are planned. The Exhibit 2 Jan. 31, 2024 Item #2 Page 8 of 153 Miller Marine Science & Consulting, Inc. 26895 Aliso Creek Road, Suite B-847, Aliso Viejo, CA 92656 562-714-0266, ericm@millermarinescience.com 2 laboratory’s standard turnaround time to generate testing results is currently 20 business days. Surface water will be collected from three stations along the shoreline of the south shore area west of I-5 Freeway proximate to the stations sampled in December 2021. The proposed sampling will occur from the shoreline and not from a boat. Surface water will be collected in clean sampling jars provided by the two laboratories that will be used to analyze the water for fecal indicator bacteria. If needed, a sterile van dorn bottle will be available to collect the water and dispense the collected water into the laboratory-provided sample bottles. These samples will be placed in a cooler on ice and transported to the two bacteria laboratories. One laboratory will quantify the bacteria forms (Total Coliform + E. Coli and Enterococcus) like what was done in December 2021. The second laboratory will conduct genetic microbial source tracking to determine if human- sourced fecal bacteria are present using the HF183 genetic marker. The HF183 marker is the current standard required by the Regional Water Quality Control Boards for bacteria microbial source tracking where human contributions are suspected. A total of nine water samples will be collected to support the specified bacteria tests. Quantification typically requires two bottles. Sampling Assumptions MMSC assumes the south shore area west of I-5 Freeway is accessible on foot pulling a wagon from nearby La Costa Ave. MMSC may meet with Mr. David Hill to confirm the entry points and walk the path to the sampling site during a reconnaissance visit prior to mobilizing all of the sampling equipment. The BLF will provide MMSC with all the access permissions needed including copies of the needed CA Department of Fish and Wildlife permit and their acknowledgment and acceptance of the notification. BLF also states that access to the south shore area west of I-5 Freeway is unrestricted and currently open. Additionally, the sampling site is an area of Batiquitos Lagoon a State-owned Ecological Research (Batiquitos Lagoon Ecological Reserve; BLER). Permission to access and obtain water and sediment samples has been granted to the BLF until December 31, 2024 by the California Department of Fish and Wildlife (Attachment 1). The BLF has advised MMSC that the access to the south shore area is along a natural occurring surface water runoff ravine draining to the lagoon. COST ESTIMATE Management, Field Sampling, Reporting = $13,700 Bacteria Testing = $4,725 Sediment Testing = $27,575 Total estimate = $46,000 This cost estimate is inclusive of mobilization, sediment sampling, and surface water sampling in the field inclusive of all sampling equipment described above, laboratory processing of the sediment cores, surface sediments, and water samples as described above, and a data report summarizing the final field methods and data results.

Jan. 31, 2024 Item #2 Page 17 of 153 INTRODUCTION The Batiquitos Lagoon Foundation (BLF) is concerned about the existing and future contamination of the Batiquitos Lagoon (BL) by both point and non-point source discharges into the lagoon. The area surrounding the BL was dominated by agricultural uses where pesticides and fertilizers, among other compounds, were used. Compounds used on the agricultural fields ran off into the lagoon because of irrigation and precipitation. Such runoff has established legacy contamination in the sediments. In recent decades, the area surrounding the BL has been developed to convert agricultural fields to housing and commercial uses. Stormwater management infrastructure came with development. Multiple stormwater drains have been installed along the BL shoreline using the BL as the stormwater receiving waters including a new 60-inch drain installed as part of the Leucadia Streetscape plan. The BLF contacted Miller Marine Science & Consulting, Inc. (MMSC) about surveying the sediments and water in the BL to establish a baseline as the new 60-inch storm drain begins operating. Study Question to be Investigated The primary question posed by the BLF to be addressed by the proposed sampling is to establish a baseline contamination level at ten sites within the BL. These sites represent areas that will receive discharge from the new 60-in storm drain as well as sites adjacent to the historic agricultural areas. The 60-in storm drain sites will establish a baseline for conditions during the dry season before any terrestrial deposits can accumulate. Sites near the agricultural lands will characterize the level of legacy contamination present in the BL. QUALITY ASSURANCE PROJECT PLAN Data quality is a cornerstone of science in support of regulatory decision making. Therefore, a Quality Assurance Project Plan (QAPP) is developed and will be used to ensure the final data products of the BL monitoring meet the highest standards and the goals to support any regulatory decisions that will follow. QAPP Purpose The QAPP is to ensure the work plans described below are followed. Should the need arise to adjust either plan after implementation, the necessary adjustments will be documented and reported through the project organizational structure (Figure 1). Jan. 31, 2024 Item #2 Page 18 of 153 QAPP Execution To ensure all phases of benthic monitoring are achieved to the highest quality possible, a benthic monitoring expert will be on site in the field and in the sorting laboratory to observe operations. In the field, the benthic monitoring team will maintain a checklist of operational events related to each sampling effort. Operational efforts for field or laboratory operations will include: •Benthic Sampling o All materials are present before sampling begins. Sediment grab, 2 stainless steel spoons (1 extra for redundancy), pre- labeled plastic sample bags, metric ruler, datasheets, and GPS. Water sampling equipment, e.g., Van Dorn bottle, and all laboratory- provide sample jars with required preservatives, as needed. Distilled Water used for cleaning equipment between sampling efforts; sediments and water. o Sampling is completed in accordance with the approved workplan. Especially noting the distance to target to ensure sampling is within 100 m of the target coordinates. Figure 1. Organization chart indicating the roles of each entity contributing to the effective execution of the sampling and analysis plan. The roles, responsibilities, and organization expected to complete the task are listed. Regulatory Agency Client: Represented by Point of Contact Mr. David Hill, BLF President Mr. Jeff Regan, and Technical Advisor Dr. John Helly Prime Consultant: Contracted by Permittee, oversees workplan execution, implements QAPP, assists with laboratory processing, prepares and presents final report to Permittee.

Errors will be corrected immediately and documented. The project manager will review the data submitted by the laboratory data manager and any questions will be addressed with the laboratory manager. o Reporting The report will be reviewed internally by the project management team with a draft final submitted for review to BLF. A final report incorporating comments and edits BLF will be prepared for submittal to any regulatory agency the BLF desires. SAMPLING PLAN Up to ten sampling stations will be occupied in the BL during both dry and wet season sampling (Figure 2). All ten stations will be occupied during the dry season sampling. Stations (Weston Property) S.3029.08738, S.3022.08808, and S.3020.08728 will be sampled only if runoff is observed during the wet season sampling. The remaining seven stations will be occupied during the wet season sampling. Jan. 31, 2024 Item #2 Page 20 of 153 Sediments will be collected from each station during both dry and wet season. Dry season sampling will capture the legacy contributions from seasons past. The wet season sediments will be sampled to assess the influx of new sediments that may have been deposited as a result of storm water discharge. Water will be collected at each station where enough water depth exists to safely sample without disturbing the bottom sediments. Water samples will be collected before sediment samples to avoid any contamination with sediments suspended by the sediment sampling effort. Figure 2. Batiquitos Lagoon water and sediment sampling stations proposed for dry season sampling. Water Sampling Methods •A clean, discrete-depth water grab, e.g., Van Dorn bottle, will be lowered to the approximate mid-depth of the station before being triggered to sample the water. •Sample water will be decanted into the laboratory-provided sample jars. o Ensuring any preservative needed in the jar is not splashed out of the jar. •Clean hands methods will be used for all bacteria sample collection to minimize any cross contamination. Jan. 31, 2024 Item #2 Page 21 of 153 o One sampling team member will handle the water sampling jar while wearing new, clean, disposable gloves. o The second sampling team member will record all information on the pre-printed data sheets. •Samples will be stored in accordance with laboratory requirements. o In an ice-cooled cooler or waterproof box without any temperature control depending on the sample. o Water samples will be delivered to the analytical lab within 6 hours of the first sample effort to meet bacteria testing holding time requirements. •Chemistry analysis will include those chemicals listed on Table 1. Sediment Sampling Methods Sampling will be completed in accordance with the BIGHT ’18 Sediment Quality Assessment Field Operations Manual (SCCWRP 2018). The protocol will be as follows: •Position the sampling vessel within 100 m of the designated sampling site coordinates. •A rust-free sediment grab will be used for all sampling. •Only acceptable grabs will be kept. Acceptable criteria are: o Acceptable per SCCWRP (2018) is defined as: An acceptable sample condition is characterized by an even surface with minimal disturbance and little or no leakage of the overlying water. o Sediment penetration of at least 5 cm. •Grabs will continue until sufficient sediment has been collected to support the required analyses. •Sediments will be visually inspected and characterized after sampling but before sample storage. o Sediment composition, smell, and color will be recorded. •Sediment characterization shipboard sample processing. o Samples will be taken from top 2 cm of the grab using a stainless-steel scoop. o Sediments will be transferred to 4-oz plastic container filled 80% of capacity. o Samples will be placed in cool state of approximately 4°C. Wet ice in the field and refrigerator in the laboratory achieves the needed cooling. o Chain of Custody documentation will be maintained to document the handling of the samples. Jan. 31, 2024 Item #2 Page 22 of 153 •Sediment chemistry shipboard sample processing. o Samples will be taken from top 2 cm of the grab and at least 1 cm away from the sides of the grab will be taken using a stainless-steel scoop. Scoops will be rinsed with site water and deionized water (in that order) in between stations to minimize cross-contamination o Sediments will be homogenized inside a new Teflon bag within a new, labeled food-grade bag lining a bucket to protect from cross contamination, should the Teflon bag break. The food-grade bag will be labeled with the station identification, sampling date, and sampling time. A gentle massaging of the sediments will continue for 3-5 minutes until the sample color and texture appears uniform. Chemistry analysis will include those chemicals listed on Table 1. Laboratory Processing All sampling will be completed in accordance with the requirements set forth by 40 CFR 136 or as augmented by the San Diego Regional Water Quality Control Board and/or California State Water Resources Control Board. Only ELAP-certified laboratories will be used. Each will provide DMR results to BLF or on behalf of BLF to all regulating agencies. DELIVERABLES MMSC will enter all the data into a MS-Excel spreadsheet. Tables will be compiled from the data and presented in a brief data report. The data report will include a complete detailing of the sampling effort, sample management, quality control compliance, and laboratory coordination. Where appropriate or available, the results for each analysis will be compared against regulatory thresholds implemented by the San Diego Regional Water Quality Control Board and the regional bay and estuary results from the most recent BIGHT Regional Monitoring effort.

Subject: Batiquitos Lagoon Sampling of the South Shore Area West of I-5 PURPOSE The Batiquitos Lagoon Foundation (BLF) contracted Miller Marine Science & Consulting, Inc. (MMSC) to sample water and sediments at multiple stations in the Bataquitos Lagoon in December 2021. The following proposal aims to repeat the sampling completed in 2021 and reported in January 2022. SCOPE OF WORK The scope of work represents a repeat of what was completed in 2021 and captured in the data report dated January 30, 2022 (attached as Attachment 1). Eight stations (Table 1) were sampled in 2021 and will be revisited under the proposed sampling effort. Water and sediments were collected at all stations except Station BL3. Station BL3 in Ponto Creek was not fully sampled for sediments and water in 2021. Both sediments and water will be collected at Station BL3 under the current proposal. The same chemical species will be tested for in water and sediment as detailed in the January 30, 2022 report. The water quality parameters will be measured at each station using a Eureka Manta multiprobe (or similar). These parameters will include water temperature, salinity, turbidity, dissolved oxygen, pH, and chrolophyll-a. Table 1.

Due to safety and access concerns, the MMSC team will not attempt to pass under the railroad trestle. The sampling days will be divided by the trestle with all stations west of the trestle sampled on one day and those stations east of the trestle sampled on a second day. This will allow the bacteria samples to be delivered to the analytical laboratory with the required holding time each day. The MMSC team will launch the inflatable fitted with a davit and sediment grab sampler in each area independently.

JANUARY 30, 2022 DATA REPORT AND APPENDICES Jan. 31, 2024 Item #2 Page 29 of 153 Data Report Date: January 30, 2022 Prepared For: Batiquitos Lagoon Foundation Prepared By: Miller Marine Science & Consulting, Inc. Subject: December 2021 Sampling Results PURPOSE The Batiquitos Lagoon Foundation (BLF) contracted Miller Marine Science & Consulting, Inc. (MMSC) to develop a sampling and analysis plan (SAP; Appendix 1) and implement that SAP. SAMPLING SUMMARY Eight out of 10 stations in Batquitos Lagoon and nearby Ponto Creek (Figure 1) were sampled on December 9, 2021 to asses potential sediment contamination due to historic agricultural use. The sampling event aimed to establish a baseline which would be used to compare sediment composition after future stormwater events. In addition to sediment, water samples were also collected at each site for bacterial and chemical analyses. Figure 1. Map of the ten sample sites in Batiquitos Lagoon. Jan. 31, 2024 Item #2 Page 30 of 153 Water Sampling Protocol At each of the ten stations, a Eureka Manta multiprobe was employed to calculate total depth (ft.), temperature (°F), salinity (ppt.), turbidity (NTU), dissolved oxygen (DO) (mg/l), pH, and chlorophyll a content (μg/l). Each of these parameters were recorded in one-foot increments until the bottom was reached. Upon completion of recording these data, a clean Van Dorn bottle was lowered to the approximate mid-depth to sample water at depth. The subsequent enclosed “water grab” was brought up to the surface and transferred to laboratory-provided sample jars (Table 1). Extreme care was taken to ensure no cross-contamination or spillage of chemicals and preservatives from sample jars. New disposable plastic gloves were used at each site during this process so that the samples, specifically the bacterial samples, contained no human-introduced bacteria. Multiple Van Dorn grabs were required at each station to sufficiently acquire enough seawater for each specified container. Upon collection all sample bottles were placed in a cooler on the boat and shortly thereafter transferred to a cooler onshore with ice to be delivered to the appropriate laboratory. All samples were delivered, and the analytical test started within the designated holding time. Table 1. List of laboratory-provided sample jars for seawater analyses at each site denoting bottle size, type, and preservative included, if any.

Sediment Sampling Protocol A single Van Veen grab sampler was used to collect sediment at each of the seven stations where sediment sampling occurred. A plastic ruler and stainless-steel spoon were both cleaned with DI water to limit cross-contamination. Only acceptable grabs were kept in accordance with the SCCWRP 2018 criteria: An acceptable sample condition is characterized by an even surface with minimal disturbance and little or no leakage of the overlying water. The ruler was used to measure the penetration depth, with a minimum penetration of 5 cm required for each sample. The stainless-steel spoon was used to transfer the sediment into the appropriate laboratory-provided Jan. 31, 2024 Item #2 Page 31 of 153 jar (Table 2). Sediment was only collected from the top 2 cm and 1 cm away from the sides of the Van Veen sampler. These boundaries insured the samples were not contacted by the Van Veen sampler. Grabs continued until enough sediment had been collected and the samples were homogenized by shaking their individual jars until the color and texture appeared uniform. Upon collection all sample jars were placed in a cooler on the boat and shortly thereafter transferred to a cooler onshore with ice to be delivered to the appropriate laboratory. All samples were delivered, and the analytical test started within the designated holding time. Table 2.

Water Quality Measurements – One station in Ponto Creek was sampled at the terminus to two discharges. The water temperature was 73ºF, salinity was 1.36 ppt, clarity was high with turbidity of 0.17 NTU, dissolved oxygen of 9.15 mg/L, pH of 7.96, and no chlorophyll-a detected. At least 7 crayfish (Cambarus sp.), an introduced crustacean related to rock lobster, were observed at the sampling site. Several small fish, likely introduced mosquitofish (Gambusia affinis) were also observed at the sampling station. In Batiquitos Lagoon, the water temperature averaged 60ºF with less than a 1ºF difference between the warmest and coolest temperatures recorded. Salinity averaged 33.5 ppt and ranged from 32.48 to 33.9, all within the expected salinity range common for tidally regulated seawater bodies in southern California. The waters were slightly turbid with an average turbidity of 1.9 NTU. The dissolved oxygen averaged 7.5 mg/L, while pH was slightly basic at 8.1. Chlorophyll-a concentrations were low in general. None of the sampled waters had fecal indicator bacteria levels in excess of designated Beneficial Use limits. The waters at Stations BL8 and BL10 along the Weston property had the highest relative fecal indicator bacteria (Enterococcus) levels with 96 and 99 MPN/100 ml, respectively. For comparison, the REC-1 (water contact recreation beneficial use) limit applicable to these saline waters is 110 MPN/100 ml Enterococcus. None of the samples collected in the first lagoon, Jan. 31, 2024 Item #2 Page 32 of 153 labeled the Vestibule, had concentrations exceeding 28 Enterococci MPN/100 ml. Because the Ponto Creek salinity was greater than 1 ppt, it must remain less than the Enterococcus limit of 110 MPN/100 ml, which it did with 46 MPN/100 ml. Chemistry Testing – Chemistry testing was completed on both water and sediments collected at all the stations inside the lagoon. Only water was collected for analysis at the Ponto Creek sampling site. The water was tested for multiple chemical species and compounds, but few were detected in samples from any of the stations (Appendix 2). In most cases, when a compound was detected, it was so in such low concentrations that it’s concentration could not be reliably reported. These reported values were J-flagged by the analytical laboratory. A J-flag indicates the compound was detected but not at a concentration high enough to be reliably reported. The values reported for any J-flagged compound represent an estimated value rather than a measured concentration. For the water, only calcium carbonate, nitrogen (total Kjeldahl nitrogen), and phosphorus were detected at most stations in reportable concentrations. Calcium carbonate and nitrogen concentrations were both higher in the lagoon that in Ponto Creek. There was minimal variation between the waters at each lagoon sampling station for these measurements. In comparison, phosphorus was higher in the Ponto Creek sample than any of the lagoon samples. Lastly, total dissolved and suspended solids were at lease an order of magnitude higher throughout the lagoon than they were in samples from Ponto Creek. None of the chemical concentrations were elevated to a level that can is considered hazardous or potentially hazardous. Where data exists, the reported Batiquitos Lagoon concentration was compared with an available Effects-Range-Median (ERM) concentration (Long et al. 1995). The ERMs are laboratory determined concentrations that pose either a human or environmental health risk. The Batiquitos Lagoon sampling results were also compared to the most recent Southern California Bight Regional Monitoring Program results (BIGHT ’18). As with the ERM, all Batiquitos Lagoon concentrations were less than was reported for the bay and estuary stratum in BIGHT ’18.

Jan. 31, 2024 Item #2 Page 37 of 153 INTRODUCTION The Batiquitos Lagoon Foundation (BLF) is concerned about the existing and future contamination of the Batiquitos Lagoon (BL) by both point and non-point source discharges into the lagoon. The area surrounding the BL was dominated by agricultural uses where pesticides and fertilizers, among other compounds, were used. Compounds used on the agricultural fields ran off into the lagoon because of irrigation and precipitation. Such runoff has established legacy contamination in the sediments. In recent decades, the area surrounding the BL has been developed to convert agricultural fields to housing and commercial uses. Stormwater management infrastructure came with development. Multiple stormwater drains have been installed along the BL shoreline using the BL as the stormwater receiving waters including a new 60-inch drain installed as part of the Leucadia Streetscape plan. The BLF contacted Miller Marine Science & Consulting, Inc. (MMSC) about surveying the sediments and water in the BL to establish a baseline as the new 60-inch storm drain begins operating. Study Question to be Investigated The primary question posed by the BLF to be addressed by the proposed sampling is to establish a baseline contamination level at ten sites within the BL. These sites represent areas that will receive discharge from the new 60-in storm drain as well as sites adjacent to the historic agricultural areas. The 60-in storm drain sites will establish a baseline for conditions during the dry season before any terrestrial deposits can accumulate. Sites near the agricultural lands will characterize the level of legacy contamination present in the BL. QUALITY ASSURANCE PROJECT PLAN Data quality is a cornerstone of science in support of regulatory decision making. Therefore, a Quality Assurance Project Plan (QAPP) is developed and will be used to ensure the final data products of the BL monitoring meet the highest standards and the goals to support any regulatory decisions that will follow. QAPP Purpose The QAPP is to ensure the work plans described below are followed. Should the need arise to adjust either plan after implementation, the necessary adjustments will be documented and reported through the project organizational structure (Figure 1). Jan. 31, 2024 Item #2 Page 38 of 153 QAPP Execution To ensure all phases of benthic monitoring are achieved to the highest quality possible, a benthic monitoring expert will be on site in the field and in the sorting laboratory to observe operations. In the field, the benthic monitoring team will maintain a checklist of operational events related to each sampling effort. Operational efforts for field or laboratory operations will include: • Benthic Sampling o All materials are present before sampling begins.  Sediment grab, 2 stainless steel spoons (1 extra for redundancy), pre- labeled plastic sample bags, metric ruler, datasheets, and GPS.  Water sampling equipment, e.g., Van Dorn bottle, and all laboratory- provide sample jars with required preservatives, as needed.  Distilled Water used for cleaning equipment between sampling efforts; sediments and water. o Sampling is completed in accordance with the approved workplan.  Especially noting the distance to target to ensure sampling is within 100 m of the target coordinates.

SAMPLING PLAN Up to ten sampling stations will be occupied in the BL during both dry and wet season sampling (Figure 2). All ten stations will be occupied during the dry season sampling. Stations S.3029.08738, S.3022.08808, and S.3020.08728 will be sampled only if runoff is observed during the wet season sampling. The remaining seven stations will be occupied during the wet season sampling. Jan. 31, 2024 Item #2 Page 40 of 153 Sediments will be collected from each station during both dry and wet season. Dry season sampling will capture the legacy contributions from seasons past. The wet season sediments will be sampled to assess the influx of new sediments that may have been deposited as a result of storm water discharge. Water will be collected at each station where enough water depth exists to safely sample without disturbing the bottom sediments. Water samples will be collected before sediment samples to avoid any contamination with sediments suspended by the sediment sampling effort. Figure 2. Batiquitos Lagoon water and sediment sampling stations proposed for dry season sampling. Water Sampling Methods • A clean, discrete-depth water grab, e.g., Van Dorn bottle, will be lowered to the approximate mid-depth of the station before being triggered to sample the water. • Sample water will be decanted into the laboratory-provided sample jars. o Ensuring any preservative needed in the jar is not splashed out of the jar. • Clean hands methods will be used for all bacteria sample collection to minimize any cross contamination. Jan. 31, 2024 Item #2 Page 41 of 153 o One sampling team member will handle the water sampling jar while wearing new, clean, disposable gloves. o The second sampling team member will record all information on the pre-printed data sheets. • Samples will be stored in accordance with laboratory requirements. o In an ice-cooled cooler or waterproof box without any temperature control depending on the sample. o Water samples will be delivered to the analytical lab within 6 hours of the first sample effort to meet bacteria testing holding time requirements. • Chemistry analysis will include those chemicals listed on Table 1. Sediment Sampling Methods Sampling will be completed in accordance with the BIGHT ’18 Sediment Quality Assessment Field Operations Manual (SCCWRP 2018). The protocol will be as follows: • Position the sampling vessel within 100 m of the designated sampling site coordinates. • A rust-free sediment grab will be used for all sampling. • Only acceptable grabs will be kept. Acceptable criteria are: o Acceptable per SCCWRP (2018) is defined as: An acceptable sample condition is characterized by an even surface with minimal disturbance and little or no leakage of the overlying water. o Sediment penetration of at least 5 cm. • Grabs will continue until sufficient sediment has been collected to support the required analyses. • Sediments will be visually inspected and characterized after sampling but before sample storage. o Sediment composition, smell, and color will be recorded. • Sediment characterization shipboard sample processing. o Samples will be taken from top 2 cm of the grab using a stainless-steel scoop. o Sediments will be transferred to 4-oz plastic container filled 80% of capacity. o Samples will be placed in cool state of approximately 4°C.  Wet ice in the field and refrigerator in the laboratory achieves the needed cooling. o Chain of Custody documentation will be maintained to document the handling of the samples. Jan. 31, 2024 Item #2 Page 42 of 153 • Sediment chemistry shipboard sample processing. o Samples will be taken from top 2 cm of the grab and at least 1 cm away from the sides of the grab will be taken using a stainless-steel scoop.  Scoops will be rinsed with site water and deionized water (in that order) in between stations to minimize cross-contamination o Sediments will be homogenized inside a new Teflon bag within a new, labeled food-grade bag lining a bucket to protect from cross contamination, should the Teflon bag break.  The food-grade bag will be labeled with the station identification, sampling date, and sampling time.  A gentle massaging of the sediments will continue for 3-5 minutes until the sample color and texture appears uniform.  Chemistry analysis will include those chemicals listed on Table 1. Laboratory Processing All sampling will be completed in accordance with the requirements set forth by 40 CFR 136 or as augmented by the San Diego Regional Water Quality Control Board and/or California State Water Resources Control Board. Only ELAP-certified laboratories will be used. Each will provide DMR results to BLF or on behalf of BLF to all regulating agencies. DELIVERABLES MMSC will enter all the data into a MS-Excel spreadsheet. Tables will be compiled from the data and presented in a brief data report. The data report will include a complete detailing of the sampling effort, sample management, quality control compliance, and laboratory coordination. Where appropriate or available, the results for each analysis will be compared against regulatory thresholds implemented by the San Diego Regional Water Quality Control Board and the regional bay and estuary results from the most recent BIGHT Regional Monitoring effort.
