Project CAP Consistency Checklist

Climate Action Plan Consistency Review Checklist Project #________ Development Services | 1 Civic Center Drive | San Marcos, CA 92069 | (760) 744-1050 | www.san-marcos.net

CLIMATE ACTION PLAN CONSISTENCY REVIEW CHECKLISTINTRODUCTIONThe City of San Marcos (City) adopted an updated Climate Action Plan (CAP) in .The CAP outlines strategies and measures that the City will undertake to achieve its proportional share of State greenhouse gas (GHG) emissions reduction targets. The purpose of the CAP Consistency Checklist (Checklist), in conjunction with the CAP, is to provide a streamlined review process for all proposed development projects that are subject to discretionary review and/or trigger environmental review pursuant to the California Environmental Quality Act (CEQA).Analysis of GHG emissions and potential climate change impacts from new development is required under CEQA. The City’s CAP is aqualified greenhouse gas (GHG) emissions reduction plan in accordance with State CEQA Guidelines Section 15183.5. Pursuant to CEQA Guidelines Sections 15064(h)(3), 15130(d), and 15183(b),a project’s incrementalcontribution to a cumulative GHG emissions effect may be determined not to be cumulatively considerable if it complies with the requirements of a CAP.The purpose of this Checklist is to implement GHG reduction measures from the CAP that apply to new discretionary development projects. New development would demonstrate consistency with relevant CAP strategiesand would not conflict with the City’s ability toachieve the identified GHG reduction targets through implementation of applicable measures. Projects that are consistent with the CAP, as determined through the use of this Checklist, may rely on the CAP for the cumulative impact analysis of GHG emissions.Projects that are not consistent with the CAP must prepare a comprehensive project-specific analysis of GHG emissions, including quantification of existing and projected GHG emissions and incorporation of the measures in this Checklist to the extent feasible. Cumulative GHG impacts would be significant for any project that is not consistent with the CAP.This Checklist may be updated periodically to incorporate new GHG reduction techniques or to comply with later amendments to the CAP or local, State, or federal law. Comprehensive updates to this Checklist will be coordinated with each CAP update. Administrative updates to the Checklist may occur regularly, as necessary for the purpose of keeping the Checklist up-to-date and implementable. Updates to the CAP Checklist associated with an update to the City’s CAP wouldalso require City Council approval and shall comply with CEQA. 19-0061

Development Services | 1 Civic Center Drive | San Marcos, CA 92069 | (760) 744-1050 | www.san-marcos.net APPLICABILITY AND PROCEDURES This Checklist is required only for discretionary projects1 that are subject to and not exempt from CEQA. Projects that are exempt from CEQA are deemed to be consistent with the City’s CAP, and no further review is necessary, with the exception of a Class 32 “In-Fill Development Projects” categorical exemption (State CEQA Guidelines Section 15332), for which projects are required to demonstrate consistency with the CAP through this Checklist. General procedures for Checklist compliance and review are described below. Specific guidance is also provided under each of the questions under Steps 1 and 2 of the Checklist. ▪ The City’s Development Services - Planning Division reviews development applications and makes determinations regarding environmental review requirements under CEQA. ▪ The specific applicable requirements outlined in the Checklist shall be required as conditions of project approval. ▪ The project must provide written documentation and supporting evidence that demonstrate how the proposed project would implement each applicable Checklist requirement described herein to the satisfaction of the Planning Division. ▪ If a question in the Checklist is deemed not applicable (N/A) to a project, written documentation and evidence supporting that conclusion shall be provided to the satisfaction of the Planning Division. Each Checklist question provides the scenario(s) where checking N/A may be acceptable. If a measure is deemed not applicable for reasons other than those outlined in each question, supporting evidence will need to be provided and would be subject to Planning Division approval. A project may be determined to be inconsistent with the CAP if the N/A response is deemed to be not supported by credible evidence. ▪ Development projects requiring discretionary review that cannot demonstrate consistency with the CAP using this Checklist shall prepare a separate, project-level GHG analysis as part of the CEQA document prepared for the project. 1 In this context, a project is any action that meets the definition of a “Project” in Section 15378 of the State CEQA Guidelines.

IM 19-0061 Las Posas Arco - Service Station, Car Wash & Drive Thru200 N Las Posas Road, APN 219-122-03-00Ahmad Ghaderi, A & S Engineering, Inc. 1.6 acres5,000 sf food mart; 3,000 sf car wash; 6,192 sf gas station canopy with nine fueling stationsBill VostiRincon [email protected] project would include development of a 5,000 square foot food mart with a drive thru, a 2,000 square foot car wash (with 1,000 square foot equipment room), and a 6,192 square foot gas station canopy with nine fuel dispensing stations (i.e., 18 fuel pumps). A total of 59 parking spaces would be provided in parking lot spaces with three being an electric vehicle (EV) charging space, one being a vanpool EV parking space, and two being future clean air parking spaces. Three of the 59 parking spaces would also be designated as accessible parking spaces. The proposed project would be developed on a currently vacant parcel of land with a current land use designation of MU3. The MU3 zone does not permit gas station, car wash, or food mart uses; instead, the zone is intended for job-based mixed-use developments. Job-based mixed-use developments include commercial retail, business support services, offices, government uses, and restaurants. Therefore, the development of the project would require a General Plan Amendment and Rezone to Commercial to allow for these uses 661-250-9300. [email protected]

Development Services | 1 Civic Center Drive | San Marcos, CA 92069 | (760) 744-1050 | www.san-marcos.net STEP 1: LAND USE CONSISTENCY The first step in this section evaluates a project’s GHG emissions consistent with the City’s Guidance to Demonstrating Consistency with the City of San Marcos Climate Action Plan: For Discretionary Projects Subject to CEQA (Guidance Document). New discretionary development projects subject to CEQA review that emit fewer than 500 metric tons of carbon dioxide equivalent (MTCO2e) annually would not contribute considerably to cumulative climate change impacts as stated in the City’s Guidance Document, and therefore, would be considered consistent with the CAP and associated emissions projections. For projects that are subject to CAP consistency review, the next step in determining consistency is to assess the project’s consistency with the growth projections used in the development of the CAP. This section allows the city to determine a project’s consistency with the land use assumptions used in the CAP.

Development Services | 1 Civic Center Drive | San Marcos, CA 92069 | (760) 744-1050 | www.san-marcos.net Step 1: Land Use Consistency Checklist Item (Check the appropriate box and provide an explanation and supporting documentation for your answer) Yes No 1. The size and type of projects listed below would emit fewer than 500 MTCO2e per year. Based on this threshold, does the proposed project exceed these characteristics? ▪ Single Family Housing: 36 dwelling units ▪ Multi-Family Housing: 55 dwelling units ▪ Office: 43,000 square feet ▪ Commercial Space: 20,000 square feet ▪ Regional Shopping Center: 18,000 square feet ▪ Hotel: 37 rooms ▪ Restaurant (Sit-Down): 6,500 square feet ▪ Restaurant (Drive-Thru, High Turnover): 2,400 square feet ▪ General Light Industrial: 58,000 square feet ▪ University: 263 students ▪ Mixed-Use: See Guidance to Demonstrating Consistency memorandum for methods to estimate mixed-use development thresholds ▪ Other: For project types not listed in this section the need for GHG analysis and mitigation will be made on a project-specific basis, considering the 500 MTCO2e per year screening threshold. If “Yes”, proceed to Question 2 of Step 1. If “No”, in accordance with the City’s CAP screening criteria, the project’s GHG impact is less than significant and is not subject to the measures of the CAP. ☐ ☐

2. Is the proposed project consistent with the City’s existing General Plan land use designation? If “Yes”, proceed to Step 2. If “No”, proceed to Question 3 of Step 1 ☐ ☐ 3. For projects not consistent with the existing General Plan land use designation, does the project include a General Plan Amendment that would generate GHG emissions equal to or less than estimated emissions generated under the existing designation? If “Yes”, proceed to Step 2 and provide estimated project emissions under both existing and proposed designation(s) for comparison. If “No”, the project’s GHG impact is potentially significant, and a GHG analysis must be prepared in accordance with the City’s Guidance Document and applicable CEQA guidelines. The project must incorporate each of the measures identified in Step 2 to mitigate cumulative GHG emissions impacts, along with other mitigation measures as necessary based on a project specific GHG analysis.. Proceed and complete a project specific GHG analysis, and Step 2 of the Checklist. ☐ ☐

Development Services | 1 Civic Center Drive | San Marcos, CA 92069 | (760) 744-1050 | www.san-marcos.net STEP 2: CAP MEASURES CONSISTENCY The second step of CAP consistency review is to evaluate a project’s consistency with the applicable strategies and measures of the CAP. Each Checklist item is associated with a specific GHG reduction measure in the City’s CAP. “N/A” should only be checked based on the direction provided in each Checklist Item question. All projects for which the measure is applicable must demonstrate that they would implement measures consistent with the Checklist Item, or fully substantiate how the item would be infeasible for project implementation. “N/A” responses are subject to Planning Division review and approval. If “No” is provided as a response to a question, the project would be determined to be inconsistent with the CAP and result in a significant GHG impact.

The project would include 59 on-site parking spaces; five percent of this amount would equate to three spaces. The project would comply with this requirement by providing three electric vehicle charging stations parking spaces which are proposed to be Level 2.This measure would not be applicable to the project because the project does not propose any intersection or roadway segment improvements

Development Services | 1 Civic Center Drive | San Marcos, CA 92069 | (760) 744-1050 | www.san-marcos.net Step 2: CAP Measures Consistency Checklist Item (Check the appropriate box and provide an explanation for your answer. Please use additional sheets if necessary) Yes No N/A 3. Transportation Demand Management (Measure T-9) Multi-Family Residential and Non-Residential: Will the project develop and implement a TDM plan that includes, at a minimum, all of the TDM strategies listed below? ☐ Provide discounted monthly transit pass or provide at least 25 percent transit fare subsidy to residents/employees. ☐ Provide designated car-share, carpool, vanpool, and/or park-and-ride parking spaces.2 ☐ Provide pedestrian connections between all internal uses and to all existing or planned external streets around the project site(s). ☐ Provide secure bicycle parking spaces or bicycle racks, showers, and clothes lockers. ☐ Encourage telecommuting for employees (allow one telecommute day per week or compressed work weeks) or provide a telecommute work center with common office space and equipment available to residents. -or- Would the project implement and monitor for four (4) years a TDM program that demonstrates an alternative transportation (i.e. carpool, public transit, bicycle, walk, telecommute) mode share of at least 29 percent 3 for all residents? Check “N/A” if the project is a single-family residential project or is not subject to the City’s TDM Ordinance. ☐ ☐ ☐
Please state which measure option the project for which the project would comply and substantiate how the project satisfies question 3: _________________________________ 2 The designated number of car-share, carpool, vanpool, and/or park-and-ride parking spaces provided at a rate equal to or greater than CALGreen minimum requirements. 3 Measure T-10 requires projects to increase alternative mode share by seven percent. The baseline mode share for alternative transportation (i.e. carpool, public transit, bicycle, walk, and telecommute) is 22 percent based on 2010 Census Data. This measure was developed based on a 1-2% application rate. Thus 1-2% of the total tenant-occupants are subject to comply. If the 1-2% application rate results in less than 1 tenant-occupant then this measure would not be applicable. The project is anticipated to have approximately 20 employees. 1-2% of 20 employees would represent less than half an employee. Therefore, measures such as providing discounted transit passes or bicycle spaces would not see adoption of at least one employee. The project does provide a vanpool parking space and pedestrian connections to external streets. In addition, a retail type use is not coherent with telecommuting.

This measure would not be applicable because the project only proposes non-residential uses.

Introduction

Biological Resources Assessment 1
1 Introduction
This report provides information pertaining to the existing biological resources observed by Rincon Consultants Inc. (Rincon) for the Las Posas project located within the City of San Marcos (City). The purpose of this report is to document the existing conditions of the project site, provide a determination of the resources present or potentially present at the site and assess potential mitigation options.

1.1 Project Location
The project site is located in the City of San Marcos within northern San Diego County (Figure 1).

The approximately 1.65-acre site is located southwest of the intersection of West Mission Road and North Las Posas Road and is identified as Assessor Parcel Number (APN) 219-122-03-00 (Figure 2).

The project site can be found on the San Marcos U.S. Geologic Survey (USGS) 7.5-minute topographic quadrangle in Township 12 South, Range 3 West, in the northwest quarter of Section 10 (Figure 3).

1.2 Project Description
The project includes a 5,000 square foot (sf) food mart, 2,000 sf car wash (with 1,000 sf equipment room), and 6,232 sf gas station canopy with nine fuel dispensing pumps.

1.3 Local Policies
The San Diego Association of Governments (SANDAG) North County Multiple Habitat Conservation Program (MHCP) is a comprehensive, multi-jurisdictional planning program designed to create, manage, and monitor an ecosystem preserve in northwestern San Diego County intended to protect viable populations of native plant and animal species and their habitat while accommodating economic development and quality of life for San Diego residents. The MHCP encompasses the cities of Carlsbad, Encinitas, Escondido, Oceanside, San Marcos, Solana Beach, and Vista. Its goal is to conserve approximately 19,000 acres of habitat, of which roughly 8,800 acres (46%) are already in public ownership, and contribute toward the habitat preserve system for the protection of more than 80 rare, threatened, or endangered species.

The City of San Marcos began preparing a draft of the City Subarea Plan of the MHCP in December 1999. Although the Subarea Plan has not yet been approved by the United States Fish and Wildlife Service (USFWS) and California Department of Fish and Wildlife (CDFW), the plan is a component of the adopted MHCP, and is currently being used as a guide for open space design and A & S Engineering

preservation within the City. Volume I of the Final MHCP provides a framework for city subarea plans. Though the San Marcos Subarea Plan is currently in draft form, the MHCP is used as a reference for conservation planning purposes. The Plan has identified certain areas, known as focused planning areas (FPAs), which have parcel-level preserve goals which would contribute to achieving local and regional conservation. The FPAs are represented by a combination of “hardline” preserves, indicating lands that will be conserved and managed for biological resources, and “softline” planning areas, within which preserve areas will ultimately be delineated based on further data and planning. The property does not fall within a “hardline” or “softline” area.

1.4 Surrounding Land Uses and Setting
The project site is completely surrounded by existing commercial development and heavily travelled paved roadways. The site is immediately south of West Mission Road and west of North Las Posas Road. The Inland Rail Trail runs parallel to the northern border of the site and several commercial businesses are adjacent to the western and southern borders of the site.

6 2 Methodology
Biological conditions within the project site were evaluated by confirming applicable biological regulations, policies, and standards; reviewing biological literature and querying available databases pertinent to the project site and vicinity; and conducting a reconnaissance-level biological survey of the project site. The methods employed are described in detail below. The findings and opinions conveyed in this report are based on this methodology.

Biological Resources Assessment 7

2.2 Reconnaissance Survey
Rincon Biologist Christian Nordal conducted a field survey on October 7, 2020 to document the existing conditions of the project site. All accessible portions of the project site were covered on foot. Inaccessible adjacent areas were surveyed using binoculars. Vegetation communities were mapped, and the wildlife and plants observed were noted. Site photographs from the survey are provided in Appendix A.

2.2.1 Vegetation Communities
Vegetation classification was based on the classification systems provided in the Draft Vegetation Communities of San Diego County (Oberbauer et al. 2008) to provide consistency with the MHCP; and modified as appropriate to reflect the existing site conditions. Where applicable, vegetation communities were further classified using A Manual of California Vegetation, Second Edition (Sawyer et al. 2009) to better identify the species composition and provide consistency with CDFW’s preference. Sensitive vegetation community ranking is based on MHCP habitat groups (SANDAG 2003). In addition, special status vegetation communities are ranked globally (G) and sub-nationally (S) 1 through 5 (NatureServe's 2014).

2.2.2 Flora
All plant species observed within the project site were noted, and plants that could not be identified in the field were identified later using taxonomic keys (Baldwin et al. 2012). The reconnaissance survey included a directed search for special status plants that would have been apparent at the time of the survey.

2.2.3 Fauna
Animal species observed directly or detected from calls, tracks, scat, nests, or other sign were documented. Zoological nomenclature for birds is in accordance with the California Birds Records Committee (CBRC) Official California Checklist (CBRC 2020); for mammals using Mammals of the World (Wilson and Reeder 2005); and for amphibians and reptiles using Society for the Study of Amphibians and Reptiles’ (SSAR) Checklist of the Standard English & Scientific Names of Amphibians & Reptiles (SSAR 2017).

2.2.4 Survey Limitations
The survey was conducted outside of the typical blooming period for most common and special status plant species. Additionally, the biological survey was conducted during the fall; therefore, potentially occurring overwintering species, spring migrants and certain breeding birds may not have been observed. As the survey was performed during the day, identification of nocturnal animals was limited to sign if present on site. The potential presence of special status species is based on a literature review, existing site conditions and a general biological field survey to assess habitat suitability.

2.3 Special Status Species Assessments
Local, state, and federal agencies regulate special status species and may require an assessment of their presence or potential presence to be conducted prior to the approval of proposed A & S Engineering
200 North Las Posas Road Project

8 development on a property. Assessments for the potential occurrence of special status species are based upon known ranges, habitat preferences for the species, species occurrence records from the CNDDB, species occurrence records from other sites in the vicinity of the project site, previous reports for the project site, and the results of surveys of the project site. The potential for each special status species to occur in the project site was evaluated according to the following criteria:
▪ No Potential. Habitat on and adjacent to the project site is clearly unsuitable for the species requirements (foraging, breeding, cover, substrate, elevation, hydrology, plant community, project site history, disturbance regime); for plants, the species has no recorded occurrences within 10 miles of the project site indicating that the project site may be outside of the range of the species (e.g., the species is known from coastal sage scrub, but only along the coastal margin); or, the species is conspicuous and would have certainly been identified on site if present (e.g., oak trees). The reconnaissance survey did not detect the species.
▪ Low Potential. The species is not likely to be found on the project site. Few of the habitat components meeting the species requirements are present, and/or the majority of habitat on and adjacent to the project site is unsuitable or of very poor quality, and/or there are no recent records of the species within five miles of the project. ▪ Moderate Potential. Some of the habitat components meeting the species requirements are present, and/or only some of the habitat on or adjacent to the project site is unsuitable.

The species has a moderate probability of being found on the project site. ▪ High Potential. All of the habitat components meeting the species requirements are present and/or most of the habitat on or adjacent to the project site is highly suitable. The species has a high probability of being found on the project site. ▪ Present. Species is observed on the project site or has been recorded (e.g., CNDDB, other reports) on the project site recently (within the last 5 years).

For the purpose of this report, special status species are those plants and animals listed, proposed for listing, or candidates for listing as Threatened or Endangered by the USFWS under the federal Endangered Species Act (ESA); those listed as Threatened, Endangered, or Rare by the CDFW under the California Endangered Species Act (CESA) or the Native Plant Protection Act; those designated as Fully Protected species by the state; those recognized as Species of Special Concern (SSC) by the CDFW; Covered Species identified in the MHCP; and regulations and plants occurring on lists 1 and 2 of the CNPS California Rare Plant Rank (CRPR) system per the following definitions:
▪ CRPR 1A = Plants presumed extirpated in California and either rare or extinct elsewhere; ▪ CRPR 1B = Plants rare, threatened, or endangered in California and elsewhere; ▪ CRPR 2A = Plants presumed extirpated in California but common elsewhere; and ▪ CRPR 2B = Plants rare, threatened, or endangered in California but more common elsewhere.

Additionally, CNPS assigns the following threat codes:
▪ 0.1 - Seriously threatened in California (over 80% of occurrences threatened/high degree and immediacy of threat);
▪ 0.2 - Moderately threatened in California (20-80% occurrences threatened/moderate degree and immediacy of threat); and
Methodology

Biological Resources Assessment 9
▪ 0.3 - Not very threatened in California (<20% of occurrences threatened/low degree and immediacy of threat or no current threats known).

Special status species and vegetation communities are also ranked globally (G) and sub-nationally (S) 1 through 5 based on NatureServe's (2014) methodologies:
▪ G1 or S1: Critically Imperiled Globally or Subnationally (state) ▪ G2 or S2: Imperiled Globally or Subnationally (state) ▪ G3 or S3: Vulnerable to extirpation or extinction Globally or Subnationally (state) ▪ G5 or S5: Secure Globally or Subnationally (state)
▪ ?: Inexact Numeric Rank
▪ T: Infraspecific Taxon (subspecies, varieties, and other designations below the level of species) ▪ Q: Questionable taxonomy that may reduce conservation priority A & S Engineering
200 North Las Posas Road Project

10 3 Existing Conditions

3.1 Topography and Soils
The project site consists of a graded lot surrounded by commercial development. The site is relatively flat, with elevation ranging from 570 feet above mean sea level (AMSL) at the northern boundary of the project site to 566 feet at the southwestern corner of the project site. The site is bordered by three concrete-lined v-ditches that are approximately three feet wide which border the site along the entire length of the western and southern boundaries. The v-ditch along the eastern boundary begins at the southeastern corner and continues approximately 26 feet to the north. The v-ditches direct ephemeral stormwater to a culvert in the southeast corner of the site which conveys stormwater under Las Posas Road. Stormwater flowing from the properties north of the site originates from a culvert under West Mission Road into the v-ditch on the site’s western border.

One soil type has been identified on the project site: Placentia sandy loam, 2 to 9 percent slopes (PeC) (Figure 4). The following is the official soil series description (NRCS 2020).

3.1.1 Placentia Series
Placentia sandy loam, 2 to 9 percent slopes, is mapped underlying the entire project site. The Placentia series are found on nearly level to moderately sloping sites as well as on fans and terraces.

The soils formed in alluvium from granite and other rocks of similar composition and texture.

Placentia series soils are well or moderately well drained, with slow to rapid runoff and very slow permeability. Placentia sandy loam, 2 to 9 percent slopes, has been classified as a hydric soil (NRCS 2020).

3.2 Vegetation Communities and Land Cover
A list of plant species observed on site is available in Appendix B. One land cover type was identified on the project site: disturbed land (Figure 5). Based on a review of aerial photography, the site was previously developed and has been regularly bladed since at least 1994. Current site observations from the October 2020 reconnaissance survey also indicated evidence of recent blading. As such, vegetation is limited to disturbance-adapted species and primarily consisted of shortpod mustard (Hirschfeldia incana) and telegraph weed (Heterotheca grandiflora). The v-ditches bordering the site are void of vegetation on the south and east and are overgrown with ruderal vegetation and a small tamarisk (Tamarix ramosissima) thicket on the west.

3.3 Common Wildlife
A list of the wildlife species observed during the reconnaissance survey is provided in Appendix B.

Common species observed within or adjacent to the site include house finch (Haemorhous mexicanus), Anna’s hummingbird (Calypte anna), western kingbird (Tyrannus verticalis), and mourning dove (Zenaida macroura). One common reptile, western fence lizard (Sceloporus occidentalis) and two common mammals, California ground squirrel (Otospermophilus beecheyi) and desert cottontail (Sylvilagus audubonii), were observed within the project site.

Special Status Biological Resources

Biological Resources Assessment 13
4 Special Status Biological Resources
This section evaluates the potential for the project site to support special status biological resources. Appendix C provides the complete list of all special status resources with records in the CNDDB and CNPS within a one-mile radius of the project site and within the USGS topographic quadrangle query for the project site.

4.1 Sensitive Plant Communities
No sensitive plant communities were observed on site. The project site is mapped as disturbed land which falls within the City’s “Other” habitat group and type (City of San Marcos 2001) and is considered Group F habitat per the MHCP (SANDAG 2003).

4.2 Special Status Plant Species
No special status plant species were observed on the project site during the survey. Many of the species with recorded occurrences near the project site are associated with habitats not found on the project site, including species associated with chaparral, coastal scrub, and vernal pools, which are not present on site. In addition, the project site has been previously developed and is heavily disturbed. Therefore, no special status plant species have potential to occur.

4.3 Special Status Wildlife Species
No special status wildlife species were observed on the project site during the survey. Many of the species with recorded occurrences in the project site vicinity are associated with habitats not found on the project site, such as coastal sage scrub. In addition, the project site is heavily disturbed and surrounded by existing development which further limits the suitability for wildlife species.

Therefore, no special status wildlife species have potential to occur.

Habitat within and adjacent to the project site has the potential to support native nesting birds protected by California Fish and Game Code (CFGC) 3503 and the federal Migratory Bird Treaty Act (MBTA).

4.4 Jurisdictional Waters and Wetlands
No vernal pools or wetlands were identified within the project site. Three concrete v-ditches border the project site to the east, west, and south and convey stormflows through a culvert which travels under Los Posas Road and into the municipal stormdrain system. The concrete v-ditches are ephemeral and do not support riparian vegetation. Therefore, they do not meet the definition of waters of the U.S. nor streambeds and thus, are not anticipated to be regulated by the U.S. Army Corps of Engineers or CDFW. Although the ditches are artificial and concrete lined, and do not support significant aquatic resource functions, the San Diego Regional Water Quality Control Board (RWQCB) may elect to assert jurisdiction over these features as waters of the State pursuant to the Porter-Cologne Water Quality Control Act.

A & S Engineering
200 North Las Posas Road Project

14 4.5 Wildlife Movement Corridors
Wildlife movement corridors are defined as sites that connect suitable wildlife habitat sites in a region otherwise fragmented by rugged terrain, changes in vegetation, or human disturbance.

Natural features such as canyon drainages, ridgelines, and sites with vegetation cover provide corridors for wildlife travel.

The project site and vicinity are not identified as being within a wildlife corridor based on Figure 4-2 of the City of San Marcos General Plan (2013). The project site is also not within or adjacent to a Biological Core and Linkage Area (BCLA) as illustrated in Figure 2-3 of the MHCP (AMEC Earth & Environmental, Inc., et al. 2003a, 2003b). Finally, the project is not within or adjacent to an essential connectivity site or natural landscape block as identified by the California Essential Habitat Connectivity Project (Spencer et al. 2010).

The project site does not provide suitable habitat for special status species found in the vicinity and is surrounded on all sides by commercial development and heavily travelled roadways. Therefore, the site does not occur within a wildlife movement corridor.

4.6 Local Policies and Conservation Plans
The project site occurs within the SANDAG North County MHCP area. The site is not located within a BCLA or vegetation or ecological community listed in the MHCP for conservation.

Potential Impacts and Recommended Actions

Biological Resources Assessment 15
5 Potential Impacts and Recommended
Actions

5.1 Sensitive Vegetation Communities
No sensitive vegetation communities are present on site. The project would impact approximately

1.65 acres of disturbed land which falls under Group F. The MHCP dictates no mitigation for this habitat is required within or outside of an FPA. Therefore, no further actions are required.

5.2 Special Status Plants
No special status plant species have the potential to occur on the project site. Although most species would not have been detectable during the reconnaissance survey, habitat on site is unsuitable for special status plant species documented within the project site vicinity. No impacts to special status plants would occur and no further actions are recommended.

5.3 Special Status Wildlife
No special status wildlife were detected during the reconnaissance survey. The proposed project would impact disturbed land which is surrounded by existing development and is unsuitable for special status wildlife. No impacts to special status wildlife would occur.

Habitat within and adjacent to the project site has the potential to support nesting birds species protected by CFGC Sections 3503 and 3503.5, and the MBTA. If initial ground disturbance and vegetation trimming or removal is required during the nesting bird season, the following mitigation measure will be implemented:

BIO-1 Nesting Birds and Raptors Survey
If any construction or staging activities are conducted between February 1 and September 15, a qualified biologist shall conduct a nesting bird survey no more than three days prior to the start of such activities to identify nesting birds within the project site and a 300-foot buffer around the project site (500 feet for raptors). If any nests are found, their locations shall be flagged and an appropriate avoidance buffer, ranging in size from 25 to 50 feet for song birds, and up to 500 feet for raptors depending upon the species and the proposed work activity, shall be determined and demarcated by a qualified biologist with bright orange construction fencing or other suitable flagging. Active nests shall be monitored at a minimum of once per week until it has been determined that the nest is no longer being used by either the young or adults. No disturbance shall occur within this buffer until the qualified biologist confirms that breeding/nesting is completed, and all the young have fledged. If project activities must occur within the buffer, they shall be conducted at the discretion of the qualified biologist and with monitoring and management to ensure that nesting success is not jeopardized. If no nesting birds are observed during the survey, then no further actions shall be necessary.

A & S Engineering
200 North Las Posas Road Project

16 5.4 Jurisdictional Waters and Wetlands
No vernal pools, wetlands, or riparian resources were identified within the project site and the project has been designed to avoid the concrete v-ditches bordering the site. Therefore, no direct impacts to these resources would occur. Erosion control best management practices (BMPs), such as straw wattles, should be installed along the edges of the ditches during construction to prevent discharge of sediment or other materials into the ditches.

5.5 Wildlife Movement Corridors
The project site is not within or adjacent to a wildlife movement corridor, BCLA or an essential connectivity site or natural landscape block and is surrounded by existing development. No impacts to wildlife movement corridors would occur and no further actions are recommended.

5.6 Local Policies and Conservation Plans
The project site is not within a BCLA or vegetation or ecological community listed in the MHCP for conservation. No impacts to resources protected by the MHCP would occur and no further actions are recommended.

Limitations, Assumptions, and Use Reliance

Biological Resources Assessment 17
6 Limitations, Assumptions, and Use
Reliance
This Biological Resources Assessment has been performed in accordance with professionally accepted biological investigation practices conducted at this time and in this geographic area. The biological investigation is limited by the scope of work performed. The biological survey is limited also by the environmental conditions present at the time of the survey. In addition, general biological (or protocol) surveys do not guarantee that the organisms are not present and will not be discovered in the future within the site. In particular, mobile wildlife species could occupy the site on a transient basis, or re-establish populations in the future. Our field studies were based on current industry practices, which change over time and may not be applicable in the future. No other guarantees or warranties, expressed or implied, are provided. The findings and opinions conveyed in this report are based on findings derived from site reconnaissance, review of CNDDB RareFind5, and specified historical and literature sources. Standard data sources relied upon during the completion of this report, such as the CNDDB, may vary with regard to accuracy and completeness. In particular, the CNDDB is compiled from research and observations reported to CDFW that may or may not have been the result of comprehensive or site-specific field surveys.

Although Rincon believes the data sources are reasonably reliable, Rincon cannot and does not guarantee the authenticity or reliability of the data sources it has used. Additionally, pursuant to our contract, the data sources reviewed included only those that are practically reviewable without the need for extraordinary research and analysis.

Executive Summary

Cultural Resources Assessment (Confidential) 1
Executive Summary
A & S Engineering retained Rincon Consultants, Inc. (Rincon) on behalf of the City of San Marcos (City) to conduct a cultural resources study in support of a general plan amendment for the 200 North Las Posas Road Project (project), in the city of San Marcos, San Diego County, California.

The project proposes to develop a 5,000-square foot food mart, 2,000-square foot car wash, and 6,232-square foot gas station canopy with nine fueling dispensing pumps. The current land use designation is Mixed-Use (Nonresidential) (MU-3). A general plan amendment would be required to change the current land use designation of MU-3 to the proposed land use designation of Commercial (C). The study was completed in accordance with the requirements of the California Environmental Quality Act (CEQA) and applicable local guidelines and regulations. The City is the CEQA lead agency for the project. Rincon’s scope of work for the study included a cultural resources records search, Native American outreach, field survey, and an assessment of potential, project- related impacts to cultural resources.

The background research and field survey concluded no known archaeological resources or built environment resources are present at the project site. However, four prehistoric resources are located within 0.5 mile of the project site. Two of these resources, P-37-005581 (located approximately 0.25 mile north of the project site) and P-37-005633 (located approximately 500 feet east of the project site) are prehistoric village sites with dense artifact deposits; the latter site contains human remains. A review of soils studies and historical aerial imagery indicate the presence of alluvial soils and minimal past ground disturbance on the project site. Both factors increase the likelihood of encountering intact buried archaeological deposits during project-related ground disturbance. Based on the results of the cultural resources assessment, Rincon recommends a finding of less than significant impact to historical and archaeological resources with mitigation incorporated under CEQA.

Due to the overall sensitivity of the project area, Rincon recommends completion of Worker’s Environmental Awareness Training (WEAP) prior to the start of ground disturbance for the project and that archaeological and Native American monitoring take place during initial project-related ground disturbance. A mitigation measure for the unanticipated discovery of cultural resources during project development as a best management practice is also provided. The project is required to adhere to regulations regarding the unanticipated discovery of human remains, detailed below.

Worker’s Environmental Awareness Program
A qualified archaeologist should be retained to conduct WEAP training on archaeological sensitivity for all construction personnel prior to the commencement of any ground-disturbing activities. The archaeologist should meet or exceed the Secretary of Interior’s Professional Qualification Standards for archaeology (National Park Service [NPS] 1983). Archaeological sensitivity training should include a description of the types of cultural material that may be encountered, cultural sensitivity issues, regulatory issues, and the proper protocol for treatment of the materials in the event of a find.

2 qualified archaeologist and Native American consultant. Archaeological monitoring should be performed under the direction of an archaeologist meeting the Secretary of the Interior’s Professional Qualification Standards for archaeology (NPS 1983). Native American monitoring should be provided by a locally affiliated tribal member. Monitors will have the authority to halt and redirect work should any archaeological resources be identified during project-related activities. If archaeological resources are encountered during ground-disturbing activities, work in the immediate area must halt and the find should be evaluated for listing in the California Register of Historical Resources (CRHR). Once initial project-related, ground disturbing activities are completed, archaeological or Native American monitoring or both may be reduced or halted at the discretion of the monitors, in consultation with the lead agency, as warranted by conditions that merit such reduction or suspension.

Unanticipated Discovery of Cultural Resources
If archaeological resources are encountered during ground-disturbing activities, work in the immediate area should be halted and an archaeologist meeting the Secretary of the Interior’s Professional Qualification Standards for archaeology (NPS 1983) should be contacted immediately to evaluate the find. If necessary, the evaluation may require preparation of a treatment plan and archaeological testing for CRHR. If the discovery proves to be CRHR eligible and cannot be avoided by the project, additional work, such as data recovery excavation, may be warranted to mitigate any significant impacts to historical resources.

Human Remains
The discovery of human remains is always a possibility during ground-disturbing activities. If human remains are found, the state of California Health and Safety Code Section 7050.5 states that no further disturbance shall occur until the county coroner makes a determination of origin and disposition pursuant to Public Resources Code Section 5097.98. In the event of an unanticipated discovery of human remains, the county coroner must be notified immediately. If the human remains are determined to be prehistoric, the coroner will notify the Native American Heritage Commission, which will determine and notify a most likely descendant, who shall complete the inspection of the site and provide recommendations for treatment to the landowner within 48 hours of being granted access.

Introduction

Cultural Resources Assessment (Confidential) 3
1 Introduction
A & S Engineering (A & S) retained Rincon Consultants, Inc. (Rincon) on behalf of the City of San Marcos (City) to conduct a cultural resources study in support of a general plan amendment for the 200 North Las Posas Road Project (project), in the city of San Marcos, San Diego County, California (Figure 1). The purpose of this report is to document the tasks Rincon conducted, specifically, a cultural resources records search, Native American outreach, field survey, and an assessment of potential project-related impacts to cultural resources. The study was completed in accordance with the requirements of the California Environmental Quality Act (CEQA) and applicable local guidelines and regulations. The City is the CEQA lead agency for the current project Project Location and Description
The 1.65-acre project site is located at the southwest corner of North Las Posas Road and West Mission Road, in the west central portion of San Marcos, approximately 0.3 mile north of State Route 78. The project site is identified as Assessor’s Parcel Number 219-122-0300, and is depicted on Township 12S, Range 03W, Section 10 of the United States Geological Survey San Marcos CA 7.5- minute quadrangle.

The project site is undeveloped (Figure 2) and consists of sparse patches of exposed soil with dense grasses. Adjacent land uses include commercial developments to the north, south, east, and west, with residential development in the project vicinity to the north and west.

The proposed development entails a 5,000-square foot food mart, 2,000-square foot car wash, and 6,232-square foot gas station canopy with nine fueling dispensing pumps. The current land use designation is Mixed-Use (Nonresidential) (MU-3). A general plan amendment would be required to change the current land use designation of MU-3 to the proposed land use designation of Commercial (C).

Regulatory Setting
California Environmental Quality Act
CEQA requires a lead agency to determine whether a project may have a significant effect on historical resources (Public Resource Code [PRC] Section 21084.1) or tribal cultural resources (PRC Section 21074[a][1][A]-[B]). An historical resource is one listed or determined to be eligible for listing in the California Register of Historical Resources (CRHR); a resource included in a local register of historical resources; or an object, building, structure, site, area, place, record, or manuscript that a lead agency determines to be historically significant (CEQA Guidelines, Section 15064.5[a][1-3]).

6 If it can be demonstrated that a project will cause damage to a unique archaeological resource, the lead agency may require reasonable efforts be made to allow any or all resources to be preserved in place or left in an undisturbed state. To the extent that resources cannot be left undisturbed, mitigation measures are required (PRC Section 21083.2[a], [b]).

PRC Section 21083.2(g) defines a unique archaeological resource as an artifact, object, or site about which it can be clearly demonstrated that, without merely adding to the current body of knowledge, there is a high probability that it meets any of the following criteria:
1) Contains information needed to answer important scientific research questions and that there is a demonstrable public interest in that information 2) Has a special and particular quality such as being the oldest of its type or the best available example of its type
3) Is directly associated with a scientifically recognized important prehistoric or historic event or person
Senate Bill 18
Enacted on March 1, 2005, California Senate Bill 18 (SB 18) (California Government Code Sections 65352.3 and 65352.4) requires cities and counties to notify and consult with California Native American tribal groups and individuals regarding proposed local land use planning decisions for the purpose of protecting traditional tribal cultural places (sacred sites), prior to adopting or amending a General Plan or designating land as open space. Tribal groups or individuals have 90 days to request consultation following the initial contact.

Assembly Bill 52
On July 1, 2015, California Assembly Bill 52 (AB 52) was enacted and expanded CEQA by defining a new resource category called tribal cultural resources (TCR). AB 52 establishes that “a project with an effect that may cause a substantial adverse change in the significance of a TCR is a project that may have a significant effect on the environment” (PRC Section 21084.2). AB 52 further states that the lead agency shall establish measures to avoid impacts that would alter the significant characteristics of a TCR, when feasible (PRC Section 21084.3).

PRC Section 21074(a)(1)(A) and (B) defines TCRs as “sites, features, places, cultural landscapes, sacred places, and objects with cultural value to a California Native American tribe” and requires that they meet either of the following criteria:
1) Listed or eligible for listing in the CRHR, or in a local register of historical resources, as defined in PRC Section 5020.1(k)
2) A resource determined by the lead agency, in its discretion and supported by substantial evidence, to be significant pursuant to criteria set forth in subdivision (c) of PRC Section 5024.1. In applying these criteria, the lead agency shall consider the significance of the resource to a California Native American tribe
AB 52 also establishes a formal consultation process for California tribes regarding TCRs that must be completed before a CEQA document can be certified. Under AB 52, lead agencies are required to “begin consultation with a California Native American tribe that is traditionally and culturally affiliated with the geographic area of the proposed project.” Native American tribes to be included in the process are those that have requested notice of projects proposed under the jurisdiction of the lead agency.

Natural and Cultural Setting

2 Natural and Cultural Setting
Natural Setting
The project site is in San Marcos in northern San Diego County, approximately nine miles east of the Pacific Ocean and in the Carlsbad watershed. The project site is relatively flat with elevation ranging from 565 to 570 feet above mean sea level. Vegetation on the project site includes non-native grassland and sparse patches of sage brush scrub.

Geology and Soils
According to published geologic mapping, the project site is located in the Peninsular Ranges geomorphic province of southern California and is underlain by Mesozoic-age granitic and other intrusive crystalline rocks (United States Geologic Survey 1949). One soil series, Placentia sandy loam, has been documented within the project site (Bowman 1973). All soils within the project site are Placentia sandy loam, which generally lay on alluvial fans and terraces and consist of alluvium derived from granitoid. A typical profile of Placentia Series soils features sandy loam from 0 to 13 inches, sandy clay from 13 to 34 inches, and sandy clay loam from 34 to 63 inches (U.S. Department of Agriculture 2020).

Because of the episodic nature of alluvial sedimentation, the sudden burial of artifacts is possible, and alluvial soils have an increased likelihood of containing buried archaeological deposits (Waters 1992; Borejaza et al. 2014).

Paleoenvironment
Since the onset of the Holocene era approximately 10,000 years ago, environmental conditions have changed, rapidly influencing the distribution of flora and fauna in the region. These changes in paleoenvironmental conditions likely influenced the cultural groups who occupied the San Diego region throughout the prehistoric period.

Fast paced sea level rise during the transition from the terminal Pleistocene to the early Holocene caused the paleo-coastal landscape to transform significantly, shifting the shoreline eastward and inundating valley floors (Byrd 1996). Sea levels during this time rose by approximately 100 feet, creating steep and narrow bays (Byrd 1996). Prehistoric settlement of the San Diego River Valley is documented as early as 7000 years ago, with prehistoric groups seeking resources beyond those found in coastal areas (Gallegos 1992).

Palynological studies conducted near Las Pulgas Canyon in north San Diego County, indicate that considerable changes in local plant communities have occurred over the last 4000 years. These changes tend to be associated with a gradual transition from a wetter climate to a much drier climate (Anderson 1996). Since the arrival of Europeans in southern California, an influx of non- native species occurred that replaced many indigenous plant communities.

Changes to the paleoenvironment during the Holocene influenced the regional availability of flora and fauna available to prehistoric groups. Ongoing archaeological research actively explores the relationship between resource availability and human adaptive responses (Arnold 2001; Gallegos 2002; Raab and Larson 1997; Redman 1999). This research suggests that as resource availability began to fluctuate, some groups may have migrated from the coast to the interior, settling in the A & S Engineering
200 North Las Posas Road Project

10 inland valleys and mountain areas. Seasonal availability of resources also likely influenced settlement patterns in San Diego County.

Cultural Setting
The cultural setting for the project is presented broadly in three overviews: prehistoric, ethnographic, and historic. The prehistoric and historic overviews describe human occupation before and after European contact. The ethnographic overview provides a synchronic “snapshot” of traditional Native American culture.

Prehistory
The project site lies in what is generally described as California’s Southern Bight (Byrd and Raab 2007). This region extends from the Mexican border to Santa Monica and includes Orange and San Diego counties, western Riverside County, and the Southern Channel Islands. At European contact, the region was occupied by the Tongva, Juaneño, Luiseño, Cupeño, and Kumeyaay (Ipai and Tipai).

For the purposes of this study, the prehistoric cultural chronology for the Southern Bight is presented following Byrd and Raab (2007), who divide the chronology into the Early (9600- 5600 BCE), Middle (5600-1650 BCE), and Late (1650 BCE- 1769 CE) Holocene.

Early Holocene (ca. 9600-5600 BCE)
Evidence of Paleo-Indian occupation of southern California remains very limited. Approximately 75 sites on the southern and central California coast are known that date to 7500 years before present (BP Erlandson and Colten 1991). The earliest accepted dates for human occupation of the California coast are from the Northern Channel Islands, off the Santa Barbara coast. Daisy Cave, on San Miguel Island, dates to as early as 9600 BCE (Erlandson et al. 1996). At the Arlington Springs site on Santa Rosa Island human remains yielded a date of approximately 10,000 BCE (Johnson et al. 2002). San Diego and Orange counties and the Southern Channel Islands have not produced dates as early as these. However, radiocarbon evidence has dated early occupation of the coastal region between circa (ca.) 8000 and 7000 BCE (Byrd and Raab 2007).

Traditional models describe California’s first inhabitants as big-game hunters roaming North America during the end of the last Ice Age. As the Ice Age ended, warmer and drier climatic conditions are thought to have created wide-spread cultural responses. The pluvial lakes and streams in the desert interior began to wane and cultures dependent on these water sources migrated to areas with moister conditions, such as the southern California coast (Byrd and Raab 2007).

The San Dieguito Complex is a well-defined cultural response to these changing climatic conditions in the southern California coastal region and was originally named for the cultural sequence in western San Diego County (Rogers 1929, 1939). Leaf-shaped points and knives, crescents, and scrapers characterize the artifact assemblages throughout the region (Byrd and Raab 2007). San Dieguito sites generally show evidence of the hunting of various animals, including birds, and gathering of plant resources (Moratto 2004).

Middle Holocene (ca. 5600–1650 BCE)
The Middle Holocene is generally viewed as a time of cultural transition. During this time, the cultural adaptations of the Early Holocene gradually altered. Use of milling stone tools began to Natural and Cultural Setting

appear across most of central and southern California around 6000-5000 BCE, indicating a focus on the collection and processing of hard-shelled seeds. Environmental changes in the Southern Bight are thought to have been the key factor in these changing adaptations (Byrd and Raab 2007).

Occupation patterns indicated semi-sedentary populations focused on the bays and estuaries of San Diego and Orange counties, with shellfish and plant resources as the most important dietary components (Warren 1968). In the San Diego area, this adaptive strategy is known as the La Jolla complex.

Around 4,000 years ago, extensive estuarine silting began to cause a decline in shellfish and, thus, a depopulation of the coastal zone. Settlement shifted to river valleys, and resource exploitation focused on hunting small game and gathering plant resources (Warren 1968; Byrd and Raab 2007).

Late Holocene (ca. 1650 BCE – 1769 CE)
The Late Holocene witnessed numerous cultural adaptations. The bow and arrow were adopted sometime after 500 CE, and ceramics appeared in the area ca. 1000 CE. Populations were sustained by food surpluses, especially acorns (Kroeber 1925; Byrd and Raab 2007). Other exploited food resources include shellfish, fish, small terrestrial mammals, and small-seeded plants. Settlement patterns of the Late Holocene are characterized by large residential camps linked to smaller specialized camps for resource procurement (Byrd and Raab 2007).

Ethnographic Overview
The Luiseño occupied territory along the coast between Aliso Creek and Agua Hedionda Creek that extended inland to Santiago Peak in the north and the east side of Palomar Mountain in the south, including Lake Elsinore and the Valley of San Jose (Bean and Shipek 1978). The population of the Luiseño prior to the arrival of Europeans is believed to be approximately 3500 (O’Neil 2002).

The Luiseño language belongs to the Cupan group of the Takic subfamily of languages (previously known as Southern California Shoshonean), along with their northern and eastern neighbors, the Gabrielino and Cahuilla (Bean and Shipek 1978). The Takic subfamily is part of the Uto-Aztecan language family and its origins lie in the Great Basin (Driver 1969). The language of their southern neighbors, the Ipai, is part of the Yuman family of languages, which is related to languages spoken throughout the southwest. Linguistic studies suggest that Takic-speaking immigrants from the Great Basin displaced Hokan speakers sometime after 500 BCE. Unsurprisingly, the Luiseño cultural practices were like those of other Takic language speakers, though they also had some things in common with their Ipai neighbors.

Luiseño social structure was more rigid than other Takic-speaking groups, possibly in part because of a higher population density. They were strongly patrilineal and resided in permanent villages of between a few dozen to several hundred people, each of which was politically independent and claimed its own territory, including seasonal camps. In the smaller villages, most residents belonged to a single lineage; in the larger settlements one lineage dominated, but families of many clans were present. Ties between villages were maintained through various economic, religious, and social networks (Bean and Shipek 1978).

Father Boscana, a priest at Mission San Juan Capistrano, recorded his observations of the indigenous peoples in “Chinigchinich,” a work that Kroeber described as “the most intensive and best written account of the customs and religion of any group of California Indians in the mission days” (Kroeber 1925). Kroeber further describes the Juaneño as having well-developed religious, ritualistic, and social customs, with the center of the Luiseño religion being Chinigchinich, the last of a series of A & S Engineering
200 North Las Posas Road Project

12 heroic mythological figures. The heroes were originally from the stars and the sagas told of how they formed Luiseño religious beliefs. Initiation rites during puberty were practiced for both boys and girls, including a hallucinogenic journey in search of a spirit guide for boys and days of fasting in a heated pit for girls. Luiseño cremated and buried their dead.

Plant foods were by far the largest part of the traditional diet, with acorns representing the most important staple item (Bean and Shipek 1978). In part because of this, villages were located near reliable water sources, as large quantities of water were necessary to process acorn products. The Luiseño ate a wide variety of other plant foods, including grasses, seeds, cactus fruits, yucca, bulbs, roots, tubers, mushrooms, and other items. The Luiseño also hunted and trapped game animals such as deer, rabbit, and birds. The sea was a very important source of protein, possibly providing up to 60 percent of the diet for coastal villages (White 1962). The Luiseño caught sea mammals and fish, and gathered shellfish such as abalone, mussels, clams, and scallops.

Historic Overview
The post-Contact history of California is generally divided into three periods: the Spanish period (1769–1822), the Mexican period (1822–1848), and the American period (1848–present). These historical periods are described below.

Spanish Period (1769–1822)
Juan Rodriguez Cabrillo in 1542 led the first European expedition to observe what is now called southern California. That year, he landed on Point Loma, approximately 20 miles from the proposed project site. For more than 200 years, Cabrillo and other Spanish, Portuguese, British, and Russian explorers sailed the Alta (upper) California coast and made limited inland expeditions, but they did not establish permanent settlements (Bean 1968; Rolle 2003).

Gaspar de Portolá and Franciscan Father Junipero Serra established the first Spanish settlement in Alta California at Mission San Diego de Alcalá in 1769. This was the first of 21 missions erected by the Spanish between 1769 and 1823. The Mission San Diego de Alcalá and its associated presidio were initially built near the Kumeyaay village of Cosoy, near the present site of Old Town. However, the water supply at this location was lacking and the soil was not very fertile. Thus, the mission was moved in 1774 to its present location, near the Kumeyaay village of Nipaguay (City of San Diego 2006; Mission San Diego 2013). In 1789, Father Fermin Francisco de Lasuen founded Mission San Luis Rey de Francia, approximately 12 miles from the proposed project site. The missions were responsible for developing relationships with local Native American groups and converting the population to Christianity (Engelhardt 1927a). Diseases brought by Europeans greatly reduced the Native American population.

During the Mission period, Spain deeded ranchos to prominent citizens and soldiers, though very few in comparison to those deeded during the Mexican Period. Presidio commandants were given the authority to grant house lots and garden plots to soldiers, and sometime after 1800, soldiers and their families began to move towards the base of Presidio Hill to receive land grants from the presidio commandants (City of San Diego 2006). To manage and expand their herds of cattle on these large ranchos, colonists enlisted the labor of the surrounding Native American population (Engelhardt 1927b).

Mexican Period (1822–1848)
The Mexican period commenced when news of the success of the Mexican Revolution (1810-1821) against the Spanish crown reached California in 1822. This period was an era of extensive interior land grant development and exploration by American fur trappers west of the Sierra Nevada Mountains. The California missions declined in power and were ultimately secularized in 1834. By 1835, the presidio and Mission San Diego de Alcalá had been abandoned and lay in ruins (City of San Diego 2006). News of secularization reached Mission San Luis Rey in 1835 and it came under the control of secular administrators, many of whom gained title to mission lands (Hebert 1961; Mission San Luis Rey 2014). Pío and Andrés Pico gained ownership of Rancho Santa Margarita y las Flores after secularization, a property that is adjacent to the project site on the northwest (Hebert 1961).

The Mexican government recognized the newly established Pueblo of San Diego in 1834. The pueblo did not fare as well as other California towns during the Mexican period. Secularization of the missions caused increased hostilities by Native Americans against the Californios living in San Diego County during the late 1830s. Attacks on outlying ranchos and an unstable political and economic climate caused the pueblo’s population to drop from approximately 500 to 150 permanent residents by 1840. In 1838, San Diego was demoted from pueblo status and made a sub-prefecture of the Los Angeles Pueblo (City of San Diego 2006).

American Period (1848–Present)
The American period in San Diego County began as early as 1846 when the United States (U.S.) military occupied San Diego and effectively ended Californio resistance in 1847. The American government assumed formal control of Alta California with the signing of the Treaty of Guadalupe Hidalgo in 1848, in which the U.S. agreed to pay Mexico $15 million for the territory that included California, Nevada, Utah, and parts of Colorado, Arizona, New Mexico, and Wyoming.

During the early American period, cattle ranches dominated much of Southern California, although droughts and population growth resulted in farming and urban professions supplanting ranching through the late nineteenth century. After the U.S. took control of San Diego in 1846, the political and economic situation stabilized, and population increased. The discovery of gold in northern California in 1848 led to the California Gold Rush, which resulted in a massive population increase (Guinn 1977). By 1853, the population of California exceeded 300,000. Thousands of settlers and immigrants continued to pour into the state, particularly after the completion of the transcontinental railroad in 1869. By the 1880s, the railroads had established networks throughout southern California, resulting in fast and affordable shipment of goods, as well as means to transport new residents (Dumke 1944).

San Diego County
San Diego County was organized formally in February of 1850 and grew slowly during the 1860s. The mid-1800s saw the urbanization of San Diego thanks to the development and promotion of the area by Alonzo Horton, who offered free lots to anyone who would build a house worth $500. The Santa Fe Railroad began construction in 1880, with the first trains arriving in 1882. After several population booms, San Diego reached 35,000 residents in 1888. The population later fell to 17,000 in 1890 because of a real estate market crash (City of San Diego 2006).

The twentieth century brought further development to San Diego. John D. Spreckels launched a major building campaign to modernize the city during the first two decades of the 20th century.

Summer cottage retreats began to develop in the seaside communities of Ocean Beach and La Jolla.

A & S Engineering
200 North Las Posas Road Project

14 Improvements in public transportation allowed development to spread to the areas of University Heights, Greater North Park, and Mission Hills. In 1915, the Panama-California Exposition was held in San Diego in celebration of the opening of the Panama Canal (City of San Diego 2006).

During the 1920s, San Diego’s population grew from 74,683 to 147,897, due to the Panama- California Exposition and efforts to attract the U.S. Navy to the city. The naval and military presence provided the population and economy that allowed the city further development (City of San Diego 2006). San Diego County continues to be an important military center, and as one of the largest metropolitan areas in California, San Diego County is a popular vacation destination known for its beaches, mild climate, and urban events.

City of San Marcos
The project site is in San Marcos. In 1875, Gustavus French Merriam relocated his family from Kansas to southern California, purchasing 160 acres, on which he established an apiary and vineyard (Carroll 1975). Within a few years, the area surrounding the Merriam homestead – the first in the area – began attracting European immigrants. In 1887, the San Marcos Land Company purchased much of the surrounding land to partition into tracts available for purchase by an increasing number of families looking to move into the area. The early growth of San Marcos was aided, in large part, by its proximity to the Santa Fe Railroad Line. By 1896, the burgeoning town had a post office, school, blacksmith, and railroad depot (Carroll 1975).

Throughout the early twentieth century, San Marcos was an agriculturally driven community, with many of its residents involved in farm-related work. By 1956, 2500 residents lived in San Marcos and in 1963 the community was officially incorporated as a city. The population of San Marcos steadily expanded from 17,479 in 1980 to over 63,900 in 2018. San Marcos has continued to grow from a farming community serving the greater San Diego area to a city featuring commercial centers, a large business district, recreational activities, and an extensive higher education community with four college and university campuses (City of San Marcos 2018).

Background Research

Cultural Resources Assessment (Confidential) 15
3 Background Research
Background research for this cultural resources assessment included a records search, review of historical maps and aerial photographs, and Native American outreach. A summary of findings of each of these efforts is provided below.

California Historical Resources Information System
Staff from the SCIC at San Diego State University completed an in-house records search of the California Historical Resources Information System on September 18, 2020. The purpose of the records search was to identify previously recorded cultural resources, and previously conducted cultural resources studies at the project site and within a 0.5-mile radius. Rincon also reviewed the National Register of Historic Places (NRHP), the CRHR, the California Historical Landmarks list, the California Points of Historical Interest list, Built Environment Resources Directory, and the Archaeological Determination of Eligibility list.

Previous Studies
The SCIC records search identified 29 previous cultural resource studies conducted within a 0.5-mile radius of the project site (Appendix A). Of these, four encompassed portions of the project site.

These consist of one cultural resources technical report, one draft environmental impact report, one cultural resources monitoring report, and one cultural resources records search and literature review. None of these reports discuss details related to the six cultural resources recorded within

0.5-mile of the project site that are not documented in the resource records explained further in Section 3.1.2, below.

Previously Recorded Resources
The SCIC records search identified six cultural resources previously recorded within a 0.5-mile radius of the project site (Table 1), none of which are within the project site. The cultural resources consist of four prehistoric sites, one historic-era refuse scatter associated with the remnants of a residence, and one historic-era road alignment. Descriptions of the four prehistoric sites (P-37-005581, P-37- 005584, P-37-005633, and P-37-008815) are provided below.

P-37-005581
Located approximately 0.25-mile northeast or the current project site, resource P-37-005581 was initially recorded in 1978 by Gary Varner, who first documented the site as 20 bedrock grinding slicks with a sparse scatter of debitage. A 2005 data recovery program conducted by Philip de Barros further defined the resource as a habitation site that specialized in the production and use of adzes for woodworking. Artifacts recovered by de Barros include manos, metates, a steatite net sinker, hammerstones, flake and biface blanks, and preforms, projectile points, ceramics, biface fragments, adzes, two ceramic tobacco pipe fragments, and abundant debitage including adze re-sharpening flakes. Site chronology was assessed through obsidian hydration, which placed occupation of the site from between 3,730 to 3,160 years BP and through radiocarbon date and temporally diagnostic artifacts, which placed occupation at the site to around 1100 BP. Subsequent testing by Becker in 2009 established an approximate 1,000 square meter boundary for the site. Becker also recommended P-37-005581 as not eligible for the CRHR. However, it was recommended that archaeological and Native American monitors be present during any ground disturbance within the recorded boundary of the site.

In 2019, Helix Environmental Planning and the Rincon Band of Luiseño Indians conducted monitoring of construction within the recorded boundary of the site. Several more prehistoric artifacts were observed during monitoring, including three granitic manos, three cobbles that were possibly ground, two metavolcanic flaked tools, three metavolcanic debitage fragments, one quartz debitage fragment, and six fire-affected granitic rocks.

P-37-005584
Recorded in 1977 by Randy Franklin, resource P-37-005584 consists of one grinding slick in a boulder outcrop on a small knoll with an adjacent artifact scatter comprised of felsite flakes, hammerstone, and core fragments. The resource is located approximately 500 feet northeast of the project site.

P-37-005633
Located approximately 500 feet east of the current project site and directly south of the North County Transit District Sprinter Rail Line, resource P-37-005633 was first recorded by Randy Franklin in 1977 as seven milling slicks spread along 25 square meters of bedrock outcrop. In 1990, Gallegos Background Research

and Pigniolo tested the site and encountered a historic component consisting of early domestic refuse.

In 2002, Gallegos & Associates conducted a data recovery program that consisted of 67 hand dug units and 11 mechanically excavated trenches. The 67 units produced 93 biface/projectile points, two battered implements, two cores, 13,360 debitage, 15 manos, 5 metate fragments, 14 groundstone fragments, two shaped stones, one steatite pendant, 59 ceramic fragments, one baked clay object, one Olivella shell bead, five bone tools, 264 grams of faunal, 125 grams of shell and 201 historic artifacts. The 11 trenches produced one projectile point, two manos, two metate fragments, and one milling implement. Overall, 14 milling features with 35 elements (22 slicks, 9 saucers, and 4 cupules) were identified. Gallegos characterized P-37-005633 as a habitation site also employed as a stone tool production and food processing center.

Site chronology was addressed through the radiocarbon dating of five samples of shell, which placed occupation of the site from between 850 to 330 BP. Human remains were recovered at the site and were given to Mark Mojado of the San Luis Rey Band of Mission Indians for reburial. The site was recommended as eligible for nomination for listing in the NRHP.

P-37-008815
Recorded in 1981 by Linda Roth, resource P-37-008815 consists of a flake scatter comprised of five basalt and quartzite flakes located on a low knoll approximately 0.5-mile northeast of the project site.

Historical Imagery Review
Rincon also reviewed available historical aerial photographs and topographic maps to determine past land use within the project area (NETRonline 2020). Aerial imagery from 1938 and 1947 depict the project area as undeveloped with patches of grass and a stand of trees along the northern border of the project site. Aerial photographs from 1953 indicate the trees were cleared and a building was constructed in their former location between 1947 and 1953. Historical newspaper advertisements establish that the building was used as an auction house during the 1970s (Newspapers.com 2020). No further development of the project area is evident from aerial imagery until 1980, when aerial photographs depict the addition of a paved lot south of the building within the project site. Aerial imagery from 1993 through 1996 indicate the southern portion of the lot was used to store several shipping containers, trailers, and/or other small structures. The building, paved lot, and various other structures are no longer evident in aerial imagery from 2005. Aerial imagery from 2005 through 2016 depict the project site as vacant with elements of the property’s previous development no longer present.

Native American Outreach
Rincon contacted the Native American Heritage Commission (NAHC) on September 18, 2020, to request a Sacred Lands File search of the project site and a 0.5-mile radius surrounding it. As part of this request, Rincon asked the NAHC to provide a list of Native American groups and/or individuals culturally affiliated with the area who may have knowledge of cultural resources within the project site. These letters are for information gathering purposes only and do not constitute formal consultation under SB 18 of 2005 or AB 52 of 2015. The City will conduct separate consultation under SB 18 and AB 52.

200 North Las Posas Road Project

18 The NAHC responded on September 30, 2020 stating negative results and provided a list of Native American tribes who may have knowledge of cultural resources in the project area. 30 Native American contacts were provided by the NAHC as possibly having information regarding the project site. Rincon prepared letters to each of the NAHC-listed contacts, requesting they contact Rincon if they know of any Native American cultural resources within or immediately adjacent to the project area. Due to the COVID-19 epidemic and statewide closure of offices, the letters were sent via email on October 1, 2020.

On October 4, 2020, Clint Linton responded on behalf of the Iipay Nation of Santa Isabel, stating that he is not aware of any cultural resources within the project site and defers consultation to the San Luis Rey Band of Mission Indians. On October 12, 2020, Shasta Gaughen responded on behalf of the Pala Band of Mission Indians, stating that the project site is outside of the boundaries of what the tribe considers its Traditional Use Area (TUA). Because of the project site’s proximity to the tribe’s TUA, Ms. Gaughen requests that any documentation of newly identified cultural resources be provided to the tribe. On October 16, 2020, Cheryl Madrigal responded on behalf of the Rincon Band of Luiseño Indians (Band), stating that the project site is within Luiseño territory, within the Band’s specific area of historic interest, and that the Band has knowledge of cultural resources within 1.0 mile of the project area. Furthermore, the Band requests formal government-to- government consultation with the lead agency to further learn about the project and potential impacts to cultural resources.

Rincon forwarded the response letters from the Rincon Band of Luiseño Indians and the Pala Band of Mission Indians to A & S to be sent to the City. As of the submission of the report, no other responses have been received from Rincon’s letters sent on October 1, 2020.

Field Survey

Cultural Resources Assessment (Confidential) 19
4 Field Survey
Methods
On September 30, 2020, Rincon Archaeologist Rachel Bilchak performed a field survey of the project site. Ms. Bilchak carefully examined areas for artifacts (e.g., flaked stone tools, tool-making debris, stone milling tools, ceramics, fire-affected rock), ecofacts (marine shell and bone), soil discoloration potentially indicative of the presence of a cultural midden, soil depressions, and features indicative of the former presence of structures or buildings (e.g., standing exterior walls, postholes, foundations) or historic debris (e.g., metal, glass, ceramics). Ground disturbances such as burrows and drainages were also visually inspected. Transect spacing throughout the exposed surfaces of the project site was no more than 15 meters. Ms. Bilchak documented the field survey using field notes and digital photographs. Copies of both are maintained at Rincon’s Carlsbad office.

Results
There was low ground visibility (approximately 10 percent) during the survey due to ankle high grass throughout most of the project area (Figure 3). The south, west, and north borders of the project site contain waist high weeds and vegetation (Figure 4 and Figure 5). Modern trash was also scattered throughout. Ground disturbance, likely from ground squirrels, is evident in the southwest quadrant of the project site. Here, and elsewhere on the project site, exposed soil consists of medium brown sandy loam, typically intermixed with gravel (Figure 6). The south and west borders of the project area slope downward at an approximately 60-degree angle (Figure 7). Aside from sparse scatters of brick fragments, no sign of the property’s previous development was evident. No cultural resources were identified during the survey.

Findings and Recommendations

Cultural Resources Assessment (Confidential) 23
5 Findings and Recommendations
The current study included a cultural resources records search, Native American outreach, and field survey. The background research and field survey concluded no known prehistoric archaeological resources or built environment resources are within the project site. However, four prehistoric resources are located within 0.5-mile of the project site. Two of these resources, P-37-005581 (located approximately 0.25-mile north of the project site) and P-37-005633 (located approximately 500 feet east of the project site) are prehistoric village sites with dense artifact deposits, and the latter site contains human remains. A review of soils studies and historical aerial imagery indicate the presence of alluvial soils and minimal past ground disturbance within the project site. Both factors increase the likelihood of encountering intact buried archaeological deposits during project- related ground disturbance. Based on the results of the cultural resources assessment, Rincon recommends a finding of less than significant impact to historical and archaeological resources with mitigation incorporated under CEQA.

Due to the overall sensitivity of the project area, Rincon recommends completion of Worker’s Environmental Awareness Program (WEAP) training prior to the start of ground disturbance for the project and archaeological and Native American monitoring take place during initial project related ground disturbance. Additional recommendations have been made in the event an unanticipated discovery is made or human remains are encountered during the project.

Additional recommendations have been made in the event an unanticipated discovery of cultural resources during project development as a best management practice. The project is also required to adhere to regulations regarding the unanticipated discovery of human remains, detailed below.

Worker’s Environmental Awareness Training
A qualified archaeologist should be retained to conduct WEAP training on archaeological sensitivity for all construction personnel prior to the commencement of any ground-disturbing activities. The archaeologist should meet or exceed the Secretary of Interior’s Professional Qualification Standards for archaeology (NPS 1983). Archaeological sensitivity training should include a description of the types of cultural material that may be encountered, cultural sensitivity issues, regulatory issues, and the proper protocol for treatment of the materials in the event of a find.

Archaeological and Native American Monitoring
Rincon recommends archaeological and Native American monitoring during initial project-related, ground-disturbing activities (e.g., grubbing and grading). A qualified archaeologist and Native American consultant should conduct this monitoring. Archaeological monitoring should be performed under the direction of an archaeologist meeting the Secretary of the Interior’s Professional Qualification Standards for archaeology (NPS 1983). A locally affiliated tribal member should provide Native American monitoring. Monitors will have the authority to halt and redirect work should any archaeological resources be identified during project-related activities. If archaeological resources are encountered during ground-disturbing activities, work in the immediate area must halt and the find should be evaluated for listing in the California Register of Historical Resources (CRHR) and National Register of Historic Places (NRHP). Once initial project- related, ground disturbing activities are completed, archaeological or Native American monitoring A & S Engineering

24 or both may be reduced or halted at the discretion of the monitors, in consultation with the lead agency, as warranted by conditions that merit such reduction or suspension.
