The Draft IS/MND concluded that the project could result in potentially significant impacts to Biological Resources, Cultural PLANNING COMMISSION RESOLUTION 7572 Resources, Geology/Soils (paleontological resources), and Tribal Cultural Resources and that all the potentially significant impacts of the project can be avoided or reduced to a level less than significant with implementation of mitigation measures; and WHEREAS, the city provided notice of the availability of the Draft IS/MND and its intent to adopt an IS/MND to and sought comments from all interested individuals and agencies on the Draft IS/MND as required by CEQA: x Publishing “Notice of Intent to Adopt a Mitigated Negative Declaration” in the San Diego Union Tribune newspaper on Oct. 24, 2025. x Submitting a notice to the County Clerk of the County of San Diego and the State Clearinghouse (State Clearinghouse No. 2025100975) for posting. x Providing copies of the notice to individuals and organizations that previously submitted written requests for the notice. x Posting of the notice and Draft IS/MND on the City of Carlsbad Planning Department webpage; and WHEREAS, the Draft IS/MND was issued for a 30-day public review period, which began on Oct. 24, 2025, and ended on Nov. 24, 2025, in conformance with Public Resources Code section 21091(b) and CEQA Guidelines sections 15072 and 15105(b). The city received six comment letters from a public agency, resident, organizations, and a tribal government on the Draft IS/MND during the public review period. A Response to Comments (RTC) document was prepared and responds to all the comment letters received on the Draft IS/MND. The Draft IS/MND, together with the RTC, are collectively referred to herein as the Final IS/MND, State Clearinghouse No. 2025100975 (Attachment “A”); and WHEREAS, upon approving a project for which an IS/MND is adopted, the Lead Agency must also adopt a Mitigation, Monitoring or Reporting Program (MMRP) pursuant to Public Resources Code Section 21081.6 and CEQA Guidelines Section 15074(d); and WHEREAS, the City duly noticed a public hearing of the El Camino Real Widening Project, Arenal Road to La Costa Avenue, on March 18, 2026, to consider recommending adoption of the Final IS/MND and MMRP, and recommending approval of the project. Evidence was submitted to and considered by the Planning Commission, including, without limitation: x Written information including all application materials and other written and graphical information posted on the project website. x Oral testimony from city staff, interested parties, and the public. x The Planning Commission staff report, dated March 18, 2026, which along with its attachments, is incorporated herein by this reference as though fully set forth herein. x Additional information submitted during the public hearing; and WHEREAS, CEQA Guidelines section 15074(b) states that prior to approving a project, the Lead Agency must consider the proposed IS/MND together with any comments received during the public review process; and WHEREAS, the Record of Proceedings upon which the Planning Commission bases its decision includes, but is not limited to: (1) the Final IS/MND and the appendices and technical reports cited in and/or relied upon in preparing the Final IS/MND and MMRP; (2) the staff reports, city files and records and other documents, prepared for and/or submitted to the city relating to the Final IS/MND, MMRP, and the project itself; (3) the evidence, facts, findings and other determinations set forth in herein; (4) the General Plan and the Carlsbad Municipal Code; (5) all designs, plans, studies, data and correspondence submitted to the city in connection with the Final IS/MND, the MMRP, and the project itself; (6) all documentary and oral evidence received at public workshops, meetings, or hearings or submitted to the city during the comment period relating to the Final IS/MND and MMRP and/or elsewhere during the course of the review of the project itself; (7) all other matters of common knowledge to the to the city, including, but not limited to, city, state, and federal laws, policies, rules, regulations, reports, records and projections related to development within the city and its surrounding areas. NOW, THEREFORE, BE IT RESOLVED by the Planning Commission of the City of Carlsbad as follows: 1. Record and Basis for Action. The Planning Commission has considered the full record before it, which includes the Record of Proceedings. Furthermore, the recitals set forth above are found to be true and correct and material to this resolution and are incorporated herein by reference. 2. The IS prepared for the project identifies potentially significant effects on the environment, but (a) revisions in the project plans or proposals made by, or agreed to by, the applicant before the proposed IS/MND were released for public review would avoid the effects or mitigate the effects to a point where clearly no significant effect on the environment would occur, and (b) there is no substantial evidence, in light of the whole record before the Lead Agency, that the project as reviewed may have a significant effect on the environment. 3. A Final IS/MND has been prepared in compliance with all requirements contained in CEQA, the CEQA Guidelines, and the Carlsbad Municipal Code. 4. In determining whether the proposed project has a significant effect on the environment, the Planning Commission is able to base its decision on substantial evidence and has complied with Public Resources Code Section 21082.2. Mitigation measures were developed to reduce potential impacts to biological resources, cultural resources, geology/soils (paleontological resources), noise, and tribal cultural resources. The Developer has agreed to implement all mitigation measures identified in the Final IS/MND in order to reduce all potentially significant environmental impacts to a less-than-significant level, in accordance with the MMRP (Attachment “A”). Mitigation measures incorporated as part of the project’s conditions of approval reduce impacts to a level less than significant, therefore an IS/MND is appropriate for adoption. The Planning Commission hereby finds that after considering the public comments received and the evidence and testimony before it, that the Final IS/MND reflects the independent judgement of the city as the Lead Agency. The IS/MND, inclusive of the RTC, has been prepared in accordance and full compliance with CEQA and CEQA Guidelines, has been made available and circulated for review and comment by interested members of the public and relevant agencies as required by law, and has been presented to, reviewed and considered by this Planning Commission prior to the decision on the project. Therefore, the Planning Commission does hereby find that on the basis of the whole record before it, that there is no substantial evidence that the project, as revised and conditioned, will have a significant effect on the environment. The Planning Commission adopts the Final IS/MND, which includes the MMRP (Attachment “A”), as the valid environmental review for this project. The Planning Commission further finds that the Record of Proceedings has been completed in compliance with CEQA and the State CEQA Guidelines, and that the findings related to the Final IS/MND, taken together, reflect the independent judgment of the Planning Commission. 5. The custodian of the documents and other materials which constitute the record of proceedings upon which this decision is based in the Office of the City Clerk of the City of Carlsbad, 1200 Carlsbad Village Drive, Carlsbad, CA 92008. BE IT FURTHER RESOLVED that the Planning Commission directs the Director of Community Development to file the notice of determination required by Public Resources Code Section 21152(a) within five days after project approval. NOTICE TO DEVELOPER An appeal of this decision to the City Council must be filed with the City Clerk at 1200 Carlsbad Village Drive, Carlsbad, California, 92008, within ten (10) calendar days of the date of the Planning Commission’s decision. Pursuant to Carlsbad Municipal Code Chapter 21.54, section 21.54.150, the appeal must be in writing and state the reason(s) for the appeal.

Because regional air quality standards have been established for these criteria pollutants to protect the public with a margin of safety from adverse health impacts due to exposure to air pollution, these trigger levels can also be used to assess project emissions and inform the project’s impacts to regional air quality and health risks under CEQA. These thresholds are also consistent with the air quality significance thresholds used in the City of Carlsbad General Plan Update EIR (September 2015). 2 As the SDAPCD screening level thresholds in Rule 20.2 do not include a threshold for VOC emissions, ĐŽŶƐŝƐƚĞŶƚǁŝƚŚŽƵŶƚǇŐƵŝĚĂŶĐĞ͕ƚŚĞVOC threshold is based on the significance thresholds recommended by ƚŚĞDŽŶƚĞƌĞǇĂǇhŶŝĨŝĞĚŝƌWŽůůƵƚŝŽŶŽŶƚƌŽůŝƐƚƌŝĐƚĨŽƌƚŚĞEŽƌƚŚĞŶƚƌĂůŽĂƐƚŝƌĂƐŝŶ͕ǁŚŝĐŚŚĂƐƐŝŵŝůĂƌ ĨĞĚĞƌĂůĂŶĚƐƚĂƚĞĂƚƚĂŝŶŵĞŶƚƐƚĂƚƵƐĂƐƚŚĞ^ĨŽƌŽǌŽŶĞ͘ AFFECTED ENVIRONMENT dŚĞƉƌŽƉŽƐĞĚƉƌŽũĞĐƚŝƐǁŝƚŚŝŶƚŚĞ^͘dŚĞ^ŝŶĐůƵĚĞƐũƵƌŝƐĚŝĐƚŝŽŶƐǁŝƚŚŝŶ^ĂŶŝĞŐŽŽƵŶƚǇ͘ŝƌ ƋƵĂůŝƚǇƌĞŐƵůĂƚŝŽŶŝŶƚŚĞ^ŝƐĂĚŵŝŶŝƐƚĞƌĞĚďǇ^W͘ /ŶĚŝǀŝĚƵĂůĂŝƌƉŽůůƵƚĂŶƚƐĂƚĐĞƌƚĂŝŶĐŽŶĐĞŶƚƌĂƚŝŽŶƐŵĂǇĂĚǀĞƌƐĞůǇĂĨĨĞĐƚŚƵŵĂŶŽƌĂŶŝŵĂůŚĞĂůƚŚ͕ƌĞĚƵĐĞ ǀŝƐŝďŝůŝƚǇ͕ĚĂŵĂŐĞƉƌŽƉĞƌƚǇ͕ĂŶĚƌĞĚƵĐĞƚŚĞƉƌŽĚƵĐƚŝǀŝƚǇŽƌǀŝŐŽƌŽĨĐƌŽƉƐĂŶĚŶĂƚƵƌĂůǀĞŐĞƚĂƚŝŽŶ͘^ŝǆĂŝƌ ƉŽůůƵƚĂŶƚƐŚĂǀĞďĞĞŶŝĚĞŶƚŝĨŝĞĚďǇƚŚĞh͘^͘PA and the CZ ĂƐďĞŝŶŐŽĨĐŽŶĐĞƌŶ͕ďŽƚŚŽŶĂŶĂƚŝŽŶǁŝĚĞ ĂŶĚƐƚĂƚĞǁŝĚĞůĞǀĞů͗ŽǌŽŶĞ1͖K͖EK2͖^K2͖ůĞĂĚ͖ĂŶĚƉĂƌƚŝĐƵůĂƚĞŵĂƚƚĞƌ;WDͿ͕ǁŚŝĐŚŝƐƐƵďĚŝǀŝĚĞĚŝŶƚŽƚǁŽ ĐůĂƐƐĞƐďĂƐĞĚŽŶƉĂƌƚŝĐůĞƐŝǌĞ͗WD10͖ĂŶĚWD2.5͘ĞĐĂƵƐĞƚŚĞĂŝƌƋƵĂůŝƚǇƐƚĂŶĚĂƌĚƐĨŽƌƚŚĞƐĞĂŝƌƉŽůůƵƚĂŶƚƐ are regulated using human and environment health-based criteria, they are commonly referred to as ĐƌŝƚĞƌŝĂĂŝƌƉŽůůƵƚĂŶƚƐ͘ IMPACT ANALYSIS a)ŽŶĨůŝĐƚǁŝƚŚŽƌŽďƐƚƌƵĐƚŝŵƉůĞŵĞŶƚĂƚŝŽŶŽĨƚŚĞĂƉƉůŝĐĂďůĞĂŝƌƋƵĂůŝƚǇƉůĂŶ͍ >ĞƐƐƚŚĂŶ^ŝŐŶŝĨŝĐĂŶƚ/ŵƉĂĐƚ͗ dŚĞƉĞƌŝŽĚŝĐǀŝŽůĂƚŝŽŶƐŽĨEY^ĂŶĚY^ŝŶƚŚĞ^͕ƉĂƌƚŝĐƵůĂƌůǇĨŽƌ ŽǌŽŶĞŝŶŝŶůĂŶĚĨŽŽƚŚŝůůĂƌĞĂƐ͕ƌĞƋƵŝƌĞƚŚĂƚĂƉůĂŶďĞĚĞǀĞůŽƉĞĚŽƵƚůŝŶŝŶŐƚŚĞƉŽůůƵƚŝŽŶĐŽŶƚƌŽůƐƚŚĂƚǁŝůů ďĞƵŶĚĞƌƚĂŬĞŶƚŽŝŵƉƌŽǀĞĂŝƌƋƵĂůŝƚǇ͘/Ŷ^ĂŶŝĞŐŽŽƵŶƚǇ͕ƚŚŝƐĂƚƚĂŝŶŵĞŶƚ ƉůĂŶŶŝŶŐƉƌŽĐĞƐƐŝƐĞŵďŽĚŝĞĚ 1 KǌŽŶĞŝƐŶŽƚĞŵŝƚƚĞĚĚŝƌĞĐƚůǇŝŶƚŽƚŚĞĂŝƌ͕ďƵƚŝƐĨŽƌŵĞĚƚŚƌŽƵŐŚĂƐĞƌŝĞƐŽĨƌĞĂĐƚŝŽŶƐŝŶǀŽůǀŝŶŐǀŽůĂƚŝůĞŽƌŐĂŶŝĐĐŽŵƉŽƵŶĚƐ ;sKƐͿĂŶĚŽǆŝĚĞƐŽĨŶŝƚƌŽŐĞŶ;EKXͿŝŶƚŚĞƉƌĞƐĞŶĐĞŽĨƐƵŶůŝŐŚƚ͘sKƐĂŶĚEKX ĂƌĞƌĞĨĞƌƌĞĚƚŽĂƐ͞ŽǌŽŶĞƉƌĞĐƵƌƐŽƌƐ͘͟ĞĐĂƵƐĞ ŽǌŽŶĞŝƐŶŽƚĚŝƌĞĐƚůǇĞŵŝƚƚĞĚ͕ĂŝƌƋƵĂůŝƚǇƌĞŐƵůĂƚŝŽŶƐĨŽĐƵƐŽŶƌĞĚƵĐŝŶŐƚŚĞŽǌŽŶĞƉƌĞĐƵƌƐŽƌƐ͕sKƐĂŶĚEKX.

Maintain consistency between the General Plan and Title 21 of the Carlsbad Municipal Code (Zoning Ordinance and Map) General Plan Land Use Policy 2-P.2. When uncertainty exists regarding the precise boundary of the various land use designations identified on the Land Use Map, such boundaries shall be interpreted as follows: xWhere boundaries appear to follow the centerline of a street or highway, ownership boundary lines, or topographic features such as valleys, ridgelines, or top/bottom of bluffs/slopes then the boundaries shall be interpreted to follow the lines/features they appear to follow. xWhere boundaries appear to reflect environmental and resource management considerations, boundaries shall be interpreted in a manner which is consistent with the considerations that the boundary reflects. General Plan Land Use Policy 2-P.4. Update the city’s LCP to be consistent with the General Plan. Work with the California Coastal Commission to gain permitting authority for all areas of the city in the Coastal Zone. General Plan Land Use Policy 2-P.40. Establish development standards that will preserve natural features and characteristics, especially those within coastal, hillside and natural habitat areas. General Plan Land Use Policy 2-P.42. Ensure that development on hillsides, where permitted pursuant to the hillside development regulations of the Zoning Ordinance, is designed to preserve and/or enhance the visual quality of the pre-existing topography.

Maintain an integrated open space classification system that accommodates conservation, resource production, recreation, and aesthetic needs. General Plan Open Space, Conservation, and Recreation Policy 4-P.4. Provide public access to open space areas where consistent with applicable access restrictions per the Habitat Management Plan, easements, deeds, etc. When natural open lands are privately held, acquire or negotiate for public access if the land could be used for unprogrammed recreational uses. Public access shall not be provided where sensitive resources may be threatened or damaged, where public health and safety may be compromised or where access would interfere with the managed production of resources, such as agriculture. General Plan Open Space, Conservation, and Recreation Policy 4-P.6. Require that adjustment of the boundaries of any open space area shown on the Land Use Map be allowed only if all of the following criteria are met: xThe proposed open space area is equal to or greater than the area depicted on the Land Use Map; and xThe proposed open space area is of environmental quality equal to or greater than that depicted on the Land Use Map; and xThe proposed open space area is contiguous or within close proximity to open space shown on the Land Use Map. The City Council may also adjust the boundary of any open space area shown on the Land Use Map if it finds that the adjustment is necessary to mitigate a sensitive environmental area that is impacted by development, provided the open space boundary modification preserves open space at a 2 to 1 ratio (proposed acreage to existing acreage) and is within close proximity to the original area of open space.

However, environmental analysis shall be performed for all proposed public right-of-way improvements, and if determined that there are significant adverse impacts to the value of the open space system, those impacts shall be mitigated. The adjustment of open space boundaries shall not result in the exchange of environmentally constrained lands that are designated open space on the Land Use Map for lands that are not environmentally constrained. General Plan Open Space, Conservation, and Recreation Policy 4-P.9. Maintain and implement the city’s HMP, including the requirement that all development projects comply with the HMP and related documents. Require assessments of biological resources prior to approval of any development on sites with sensitive habitat, as depicted in Figure 4-3. General Plan Open Space, Conservation, and Recreation Policy 4-P.14. Assure that development or grading on hillsides (if allowed) relates to the slope of the land in order to preserve the integrity and appearance of natural hillsides and other landforms wherever possible. General Plan Open Space, Conservation, and Recreation Policy 4-P.16. Coordinate the implementation and planning of the city’s Habitat Management Plan with the North County Multi-Species Habitat Conservation Plan. General Plan Open Space, Conservation, and Recreation Policy 4-P.19. Require a city permit for any grading, grubbing, or clearing of vegetation in undeveloped areas, with appropriate penalties for violations. General Plan Open Space, Conservation, and Recreation Policy 4-P.36. Assure that, where feasible, developments near or adjacent to bodies of water provide open space that has public access to and views of the water.

The purpose of this report is to present the results of this delineation. Note that findings herein regarding WOTUS within the proposed project are considered “potential” WOTUS; only USACE can make the official jurisdictional determination. Under contract with the City, AECOM is providing City decision makers with information on aquatic resources that could potentially be impacted from future development of the proposed project. A formal jurisdictional delineation (JD) was conducted within the proposed project area and an approximate 550-foot buffer, collectively referred to as the Biological Study Area (BSA), of the proposed project with a specific focus on the bridge spanning Encinitas Creek at the eastern edge of Batiquitos Lagoon. PROPOSED PROJECT SETTING/LOCATION The proposed project is located within the City right-of-way along El Camino Real from Arenal Road south to La Costa Avenue (Figures 1 and 2a through 2c; see Appendix A for all figures referenced herein). The proposed project is bounded by residential and commercial development to the north, east, and south, and Batiquitos Lagoon State Marine Conservation Area to the west. The elevation for the majority of the BSA ranges between sea level and approximately 100 feet above mean sea level. To access the proposed project from Interstate 5, take La Costa Avenue east to El Camino Real. The center point of the bridge is located at Latitude 33.088004 and Longitude -117.269159. REGULATORY SETTING Wetland and non-wetland waters (e.g., streams, rivers, ephemeral drainages) and associated riparian corridors occurring within California may be regulated under federal and state laws. The following section summarizes the federal and state statutes and regulations pertaining to the JD conducted for the BSA. FEDERAL Under the Clean Water Act (CWA) Section 404, USACE regulates the discharge of dredged or fill material into any aquatic feature that meets the current definition of WOTUS as defined in 33 Code of Federal Regulations (CFR) 328. El Camino Real Widening Project Jursidictional Delineation Report AECOM 2 AAmendments to the 2023 Rule On August 29, 2023, the United States Environmental Protection Agency (USEPA) and Department of the Army (the agencies) issued a final rule, to amend the final “Revised Definition of ‘Waters of the United States’” rule, published in the Federal Register on January 18, 2023. This final rule conforms the definition of “waters of the United States” to the U.S. Supreme Court’s May 25, 2023, decision in the case of Sackett v. Environmental Protection Agency. Parts of the January 2023 Rule are invalid under the Supreme Court’s interpretation of the CWA in the Sackett decision. Therefore, the agencies have amended key aspects of the regulatory text to conform it to the Court’s decision. The conforming rule, “Revised Definition of ‘Waters of the United States’; Conforming, ” as published in the Federal Register became effective on September 8, 2023. Per §328.3 Definitions (F5) (a)(1- 5) Waters of the U.S. (a)(1) - Traditional Navigable Waters, Territorial Seas, Interstate Waters (a)(2) - Impoundments (a)(3) - Tributaries (a)(4) - Adjacent Wetlands to (1) TNW, Territorial Seas, Interstate Waters, or (2) relatively permanent impoundment or tributary with continuous surface connection to those waters (a)(5) - Intrastate Lake or Pond not identified in A.1-4 that is a relatively permanent, standing or continuously flowing body of water Jurisdictional waters must now be rrelatively permanent wwaters (RPW) and must connect to downstream A1 waters (Traditional Navigable Waters (TNWs), Territorial Seas, Interstate Waters). These waters encompass only relatively permanent, standing, or continuously flowing bodies of water, such as streams, oceans, rivers, and lakes. These waters do not necessarily exclude streams, rivers, or lakes that might dry up in extraordinary circumstances, such as drought or seasonal rivers, which contain continuous flow during some months of the year but no flow during the dry months. Ephemeral drainages are likely no longer considered jurisdictional, whereas intermittent drainages would likely be jurisdictional. The new definition of aadjacent wetlands no longer includes “bordering, continuous, or neighboring.” Wetlands must have a continuous surface connection to other jurisdictional WOTUS. Wetlands lacking such a surface connection to WOTUS, including isolated wetlands (e.g., vernal pools, prairie potholes), are likely no longer considered jurisdictional. Seasonal wetlands 1 Sources: USEPA 2023e (September 8, 2023); USEPA and USACE 2023c (September 8, 2023); Federal Register/Vol. 88, No. 173/Friday, September 8, 2023/Rules and Regulations/Final Rule/p61964-61969 2 Source: USEPA 2023a (Redline Version, dated August 14, 2023). 3 Sources: USEPA 2023c; USEPA and USACE 2023b (January 18, 2023), Federal Register / Vol. 88, No. 11 / Wednesday, January 18, 2023 / Rules and Regulations/Final Rule/p3004-3144; USACE and USEPA 2023a (effective March 20, 2023) 4 Source: USEPA 2023d 5 33 CFR part 328 (Regulations); Authority: 33 U.S. C 1251 et seq. (Clean Water Act) El Camino Real Widening Project Jursidictional Delineation Report AECOM 3 with a continuous surface connection to an RPW for at least part of the year may be considered WOTUS, pending agency guidance. STATE Under Section 401 of the CWA and in accordance with the 1969 Porter-Cologne Water Quality Control Act, the RWQCB regulates the discharges of wastes, which include discharges of dredged or fill material, which may affect the quality of WOTS. WOTS include all natural wetlands and some, but not all, artificial wetlands, as well as other non-wetland features, including the oceans, lakes, and rivers. On April 2, 2019, the Water Boards (i.e., the State Water Resources Control Board and all nine RWQCBs) adopted their State Wetland Definition and Procedures for Discharges of Dredged or Fill Material to Waters of the State. This policy is the first part of the “Wetland Riparian Area Protection Policy” that defines what constitutes a wetland and how wetlands should be delineated and protected in the state (SWRCB 2019). The Procedures became effective May 28, 2020. For the purposes of this analysis, the extent of WOTS subject to the authority of RWQCB was considered to include all WOTUS, as discussed above. Under California Fish and Game Code (CFGC) Sections 1600–1616, CDFW regulates activities that would (1) substantially divert or obstruct the natural flow of a stream; (2) substantially change the bed, channel, or banks of a stream, or use any material from the bed, channel, or banks; or (3) dispose of debris or waste materials where it may pass into a stream. In practice, CDFW extends its jurisdictional limit and assertion to the top of a bank of a stream, the bank of a lake, or outer edge of the riparian vegetation, whichever is wider. Where freshwater streams flow into the ocean, CDFW usually extends its jurisdictional limit and assertion over the lagoon habitat. The proposed project occurs within the California coastal zone. Wetlands found in the “coastal zone” are regulated under the California Coastal Act and the federal Coastal Zone Management Act and are within jurisdiction of the CCC. The CCC defines wetlands as habitats that only need to meet one of the three USACE wetland criteria (presence of hydrophytic vegetation, wetland hydrology, or hydric soil). Where a municipality has a CCC-approved Local Coastal Program (LCP), permitting authority is held by the municipality rather than the CCC. However, the CCC has the right to appeal any action that is permitted administratively located within 100 feet of a CCC- jurisdictional wetland. The City of Carlsbad has a CCC-approved LCP (City of Carlsbad 1997, as amended 2019). At the time of writing this report, the City was in the process of updating its LCP; however, the LCP had not yet been finalized and approved by the CCC. The majority of the BSA is located in the City’s LCP; however, portions occurring in Batiquitos Lagoon proper have retained jurisdiction by the CCC. METHODOLOGY The jurisdictional waters delineation included two components: desktop review and field assessment. DESKTOP METHODS Prior to the field investigation, a desktop review was conducted to determine the existing conditions and historical uses of the proposed project site and the surrounding area. The following resources and previous studies were utilized: El Camino Real Widening Project Jursidictional Delineation Report AECOM 4 xNatural Resources Conservation Service Soil Survey Mapping (USDA-NRCS 2024) xHydric soils: Hydric Soils – Criteria and 2014 State List for California (USDA-NRCS 2014); Field Indicators of Hydric Soils in the United States, version 8.2 (USDA-NRCS 2018) xNational Wetlands Inventory (NWI) (USFWS 2024) xWatershed Boundary Dataset accessed via WATERS GeoViewer (USEPA 2024 ) xNational Hydrography Dataset (NHD) accessed via WATERS GeoViewer (USGS 2024) xHistorical Aerial Imagery (1994–2021) (Google 2024) xWetland (WETS) Climate Tables (NOAA 2019) xSan Diego Basin Plan (SDRWQCB 2018) FIELD ASSESSMENT METHODS On April 2, 2021, AECOM biologists Alexandra Fowler and Anthony Greco conducted a JD within the BSA. A follow-up JD was conducted on February 19 and 22, 2024, by AECOM biologists Aaron Andrews and Natasha Foti. The purpose of the 2024 follow-up JD was to confirm or refine, where needed, the 2021 mapping, which was conducted using a coarser mapping scale relative to the scale of project features. Aquatic features that meet the definition of WOTUS or WOTS include both wetlands and non- wetland waters. To be considered a wetland, all three parameters (wetland hydrology, hydric soils, and dominance of wetland vegetation) outlined in the 2008 USACE Arid West Supplement must be met (USACE 2008). Non-wetland waters were assessed to determine whether they meet the definition of an (a)(1)-(a)(4) WOTUS in 33 CFR 328. USACE defines non-wetland waters based on the presence of an ordinary high water mark.6 The aquatic features in the BSA have a continuous surface connection to Batiquitos Lagoon and therefore the Pacific Ocean. The delineation and vegetation classification were conducted in accordance with the guidance and reference documents listed below: xA Field Guide to the Identification of the Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United States (Lichvar and McColley 2008) xUpdated Datasheet for the Identification of the Ordinary High Water Mark (OHWM) in the Arid West Region of the Western United States (Curtis and Lichvar 2010) xCorps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987) xRegional Supplement to the Corps of Engineers Wetland Delineation Manual: Arid West Region (Version 2.0) (USACE 2008) xField Indicators of Hydric Soils in the United States, version 8.2 (USDA-NRCS 2018) Federal regulations (33 CFR Part 328.3(e)) define the "ordinary high water mark" as "that line on the shore established by the fluctuations of water and indicated by physical characteristics such as a clear, natural line impressed on the bank, shelving, changes in the character of soil, destruction of terrestrial vegetation, the presence of litter and debris, or other appropriate means that consider the characteristics of the surrounding areas.” El Camino Real Widening Project Jursidictional Delineation Report AECOM 5 xNational Wetland Plant List Indicator Rating Definitions. (Lichvar et al. 2018) xDraft Vegetation Communities of San Diego County (Oberbauer et al. 2008) Three wetland sample points were taken during the 2021 JD west of the bridge and El Camino Real. Three paired sample points (six total) were taken during the 2024 JD. During both surveys, three-parameter wetlands were observed in the area north of San Marcos Creek. Wetland waters boundaries were mapped based upon the species composition change and delineated along the same approximate elevation throughout the wetland. Data sheets for each sample point from 2021 and 2024 are included in Appendix B. An Apple IPAD, Arrow 1 Trimble unit (<1 meter accuracy), and the ESRI Collector application (ESRI 2024) were used to collect data to map the boundaries of the aquatic resources present. Mapped polygons were visually adjusted, as needed, to match the resources as seen on the aerial imagery, the photogrammetric topographic data, and in the field. RESULTS The results of the desktop analyses and vegetation surveys conducted for the BSA, and results of the jurisdictional delineation are presented below. HYDROLOGY The proposed project is located within the San Luis Rey-Escondido watershed (HUC 18070303) within the San Marcos Hydrologic Area. Figure 3 shows the location of the proposed project within these watersheds. The proposed project spans open water of San Marcos Creek near the terminus into Batiquitos Lagoon. Encinitas Creek also terminates into Batiquitos Lagoon in the southeast portion of the BSA (see Figures 6a through 6c). Historic Google Earth satellite imagery taken since 1993 shows open water in San Marcos Creek within the BSA. Batiquitos Lagoon and San Marcos Creek are included in the CWA Section 303(d) list of waterbodies impaired by DDE (dichlorodiphenyldichloroethylene, toxicity, benthic community effects, indicator bacteria, phosphorus, and selenium. Per the San Diego Basin Plan, the beneficial uses for the San Marcos Creek watershed include municipal and domestic water supply (MUN), agriculture supply (AGR), water contact recreation (REC1), noncontact water recreation (REC2), warm freshwater habitat (WARM), and wildlife habitat (WILD) (SDRWQCB 2018). The National Wetland Inventory shows a mosaic of aquatic features within the BSA (USFWS 2024) including tidal flats, estuarine and marine wetland, estuarine and marine deepwater habitat, freshwater emergent wetland, and freshwater forested/shrub wetland. The Antecedent Precipitation Tool (APT) was used to display rainfall conditions within the Study Area (see Graphic 1 below) (Gutenson 2023; Gutenson et al. 2023). Per data sourced from the National Oceanic and Atmospheric Administration, the APT indicated that the field visit was conducted during a period of “Normal Conditions” for the time of year, and the overall climatic conditions for the region are “Wet Season.” El Camino Real Widening Project Jursidictional Delineation Report AECOM 6 GGraphic 1. APT graph of the BSA for February 19, 2024. Note the determination that the aquatic resource delineation was completed in “normal conditions.” Location for the APT graph was Batiquitos Lagoon. El Camino Real Widening Project Jursidictional Delineation Report AECOM 7 SOILS Based on the Natural Resources Conservation Service Web Soil Survey (USDA-NRCS 2024), soils mapped within the BSA include Tidal flats; Placentia sandy loam, thick surface, 2 to 9 percent slopes; Salinas clay loam, 0 to 2 percent slopes; Huerhuero loam, 15 to 30 percent slopes; and Huerhuero-Urban land complex, 2 to 9 percent slopes (Figure 4). One of these soils, tidal flats, is considered hydric. VEGETATION The BSA consists of a variety of vegetation communities and cover types, as seen in Figures 5A through 5C. As previously noted, vegetation was classified in accordance with the City Habitat Management Plan (City of Carlsbad 2004), based on Preliminary Descriptions of the Terrestrial Natural Communities of California (Holland 1986). Seven different vegetation classifications were identified on the site. Riparian, wetland, and native upland vegetation communities found within the BSA are considered sensitive by the City. Wetland-riparian vegetation communities observed within the BSA include coastal brackish marsh, southern coastal salt marsh, southern willow scrub, southern arroyo willow riparian forest, nonnative riparian, and open water. Upland vegetation communities observed within the BSA include Diegan coastal sage scrub, coastal form. Other cover types observed within the BSA include developed/landscape/ornamental, and disturbed habitat. See Section 5.1 of the Biological Technical Report (AECOM 2024) for the proposed project for a detailed description of the vegetation communities within the BSA.

The channel exhibits deep, incised banks characterized by a 60-foot-wide OHWM and a 60- to 90-foot-wide streambed. The El Camino Real bridge marks the boundary of the coastal zone, which means the western portion of San Marcos Creek is inside the coastal zone, while the eastern portion is outside. Within this eastern portion, disturbed riparian habitat occurs along the southern banks. This habitat contains a mixture of upland and aquatic species, dominated by willow (Salix sp.; FACW 7), mulefat (Baccharis salicifolia; FAC), and black mustard (Hirschfeldia incana). No vegetation grows underneath the bridge. Additionally, stingrays were observed in the open water habitat near the bridge during the 2021 field surveys. San Marcos Creek empties into Batiquitos Lagoon, which in turn leads to the Pacific Ocean. Due to the surface connection/relatively permanent nature of the channel, as well as connection to the Pacific Ocean, San Marcos Creek is considered likely USACE-, RWQCB-, and CDFW-jurisdictional, as well CCC- jurisdictional within the coastal zone. CDFW-only streambeds and riparian habitat are also present as part of the creek. 7 An indicator status reflects the likelihood that a particular plant occurs in a wetland. The five indicator statuses are: Obligate (OBL) plants which always occurs in standing water or saturated soils, Facultative Wet (FACW) plants which nearly always occur in standing water or saturated soils, Facultative (FAC) plants which are equally likely to occur in wetland or upland environments, Facultative Upland (FACU) plants that typically occur in upland, non- wetland habitats, and Upland (UPL) plants that almost never occur in water of saturated soils. El Camino Real Widening Project Jursidictional Delineation Report AECOM 9 BBatiquitos Lagoon Batiquitos Lagoon occurs in the western portion of the BSA and is hydrologically connected to San Marcos Creek to the east, Encinitas Creek to the south, and the Pacific Ocean to the west. The lagoon is tidally influenced; however, the portion of the lagoon within the BSA is above the high tide line and lacks consistent wetland hydrology, therefore indicating the feature is nontidal within the BSA. Three wetland sample points were taken during the 2021 JD, and six sample points, both wetland and upland, were taken during the 2024 JD. During both surveys, three- parameter wetlands were observed in the area north of San Marcos Creek. Dominant vegetation species included pickleweed (Salicornia pacifica; OBL), and alkali heath (Frankenia salina; FACW). Soil investigations within these wetlands revealed hydric soil indicators in the form of depleted matrix (see Appendix B – Datasheets). Hydrology indicators included a high water table and saturation. Therefore, the portion of Batiquitos Lagoon meets the three-parameter wetland criteria and is likely USACE-, CDFW-, RWQCB-, and CCC-jurisdictional. South of San Marcos Creek within Batiquitos Lagoon, the landscape is significantly more disturbed with a mixture of upland and aquatic plants dominated by saltgrass (Distichlis spicata; FAC), alkali heath, and brome grasses (Bromus sp.) The 2024 sample points revealed one- and two-parameter wetlands throughout the area, but a lack of wetland hydrology indicators prevented the three parameter-wetland criteria from being met. Note that one of the sample points taken in 2021 (SP 1 in Appendix B) determined the presence of a three-parameter wetland; however, the 2021 JD was conducted with a more high-level approach. The 2024 results are assumed more reliable as they represent a more refined version of the 2021 JD. Therefore, the portion of Batiquitos Lagoon located south of San Marcos Creek was determined to be likely CDFW-, RWQCB-, and CCC- jurisdictional, and likely USACE-non-jurisdictional. Batiquitos lagoon consists of a matrix of saltmarsh vegetation communities, freshwater marsh vegetation communities, and open water input channels. Several disturbed, upland areas were also observed within Batiquitos Lagoon. These areas were dominated by upland invasives including black mustard and wild radish (Raphinus sativus). A sample point was taken within this habitat (see SP 3.2 in Appendix B) and none of the three-parameter wetland criteria were met. The southern portion of the BSA contains Encinitas Creek, which flows south to north where it terminates into Batiquitos Lagoon. The habitat surrounding Encinitas Creek contains a mosaic of emergent wetlands, riparian forest, and riparian scrub habitats. Waters of the U.S. San Marcos Creek, and the portion of Batiquitos Lagoon located north of San Marcos Creek (including final acreages and types) delineated within the BSA are considered potential WOTUS prior to a formal jurisdictional determination performed by USACE/USEPA. The final JD issued by USACE may remove portions of delineated waters from being considered as jurisdictional and/or may include additional waters not initially considered as jurisdictional during the field delineation (and thus not included in this Aquatic Resource Delineation Report (ARDR). WOTUS, as described in Table 1 and Figures 6a through 6c, include wetland waters (18.282 acres; Figures 6a through 6c), and non-wetland waters (1.626 acres; Figures 6a through 6c) within Batiquitos Lagoon and San Marcos Creek. El Camino Real Widening Project Jursidictional Delineation Report AECOM 10 WWaters of the State RWQCB-regulated waters within the BSA include the same WOTUS acreages noted above, plus the portion of Batiquitos Lagoon located south of San Marcos Creek (4.294 acres; Figures 6a through 6c). CDFW-regulated waters within the BSA also include all areas of WOTUS and WOTS. Additional CDFW-regulated waters include the streambed and bank, as well as additional riparian habitat. In the BSA, these CDFW-regulated waters include the riparian wetland waters adjacent to Batiquitos Lagoon (14.716 acres; Figures 6a through 6c), the bank of San Marcos Creek (0.587 acres; Figures 6a through 6c), and disturbed/bare ground within Batiquitos Lagoon (0.259 acres; Figures 6a through 6c). CCC-regulated waters include tidally and non-tidally influenced waters, and wetland waters that meet one wetland perimeter in the coastal zone. El Camino Real marks the boundary of the coastal zone; therefore, all waters and wetland waters in the coastal zone boundary (34.463 acres; Figures 6a through 6c) are under jurisdiction of the CCC. Jurisdictional Determination Within the BSA, San Marcos Creek, Encinitas Creek, and Batiquitos Lagoon meet the definition of WOTUS and are likely to be regulated under the CWA by USACE and RWQCB as traditional navigable waters. The portion of Batiquitos Lagoon (west of El Camino Real) north of San Marcos Creek meets the definition of a wetland WOTUS and is likely to be regulated under the CWA by USACE and RWQCB as adjacent wetlands. The BSA also contains potentially jurisdictional streambeds that are likely to be regulated under the CFGC, in addition to the open waters and wetlands noted above. The areas of the BSA west of the coastal zone boundary are regulated by the CCC and/or the City of Carlsbad through its LCP. DISCUSSION Development constraints and opportunities for the proposed project site are being considered by the City. Regulations, processes, and agency authorizations that may be required prior to development of the site are discussed below. The applicable process will depend on the proposed development design. CWA SECTION 404 AUTHORIZATION The delineation and analysis presented herein indicate that “potential” WOTUS are present within the BSA. Proposed discharges of fill into WOTUS would require authorization by USACE. Therefore, if proposed development of the proposed project would result in unavoidable impacts to WOTUS, a Nationwide Permit (NWP) (likely NWP 14-Linear Transportation Projects; or an Individual Permit) may be required. El Camino Real Widening Project Jursidictional Delineation Report AECOM 11 CWA SECTION 401 WATER QUALITY CERTIFICATION Proposed discharges to the aquatic resources within the BSA that are regulated under the CWA would require a companion Water Quality Certification (WQC) issued by the RWQCB. If proposed impacts qualify for authorization via an NWP, then an individual WQC would need to be obtained unless the applicable NWP has been pre-certified by the State of California. RHA SECTION 10 AUTHORIZATION Much of the lagoon area experiences tidal action. Therefore, this ARDR considers the tidal area to meet the definition of Navigable Waters (e.g., Rivers and Harbors Act [RHA] Section 10 Waters [33 CFR 329.4]). As noted previously, the portion of the lagoon within the BSA is above the high tide line and some areas lack consistent wetland hydrology indicating nontidal conditions. Proposed work in or over navigable WOTUS, e.g., the proposed pedestrian bridges over Section 10 waters, would require authorization under the RHA. Because NWP 14 authorizes activities under CWA Section 404 (described above) and RHA Section 10, RHA evaluation will be assessed by USACE through the NWP process. CDFW STREAMBED ALTERATION AGREEMENT Proposed impacts to CDFW 1602 jurisdiction within the BSA will likely require a Streambed Alteration Agreement from CDFW. COASTAL DEVELOPMENT PERMIT Because the proposed project is partially within a CCC-retained jurisdiction area and in a CCC- appealable area, a Coastal Development Permit (CDP) from both the CCC and the City may be required. Alternatively, the City may request a CDP from the CCC for the entire proposed project. CONCLUSION Any impacts to aquatic resources within the BSA will likely require USACE and RWQCB authorizations under the CWA, a Streambed Alteration Agreement with CDFW, and a CDP from the CCC and City.

Were there any recent extreme events (floods or drought)? Step 2 Site conditions during field assessment First look for changes in channel shape, depositional and erosional features, and changes in vegetation and sediment type, size, density, and distribution. Make note of natural or man-made disturbances that would affect flow and channel form, such as bridges, riprap, landslides, rockfalls etc. Step 3 Check the boxes next to the indicators used to identify the location of the OHWM. OHWM is at a transition point, therefore some indicators that are used to determine location may be just below and above the OHWM. From the drop-down menu next to each indicator, select the appropriate location of the indicator by selecting either just below `b', at `x', or just above `a' the OHWM. OHWM. Go to page 2 to describe overall rationale for location of OHWM, write any additional observations, and to attach a photo log.
