(Appendix Q) 4.10.1 Environmental Setting The Project Site consists primarily of disturbed and vacant land. The topography of the Project Site is relatively flat, and slopes gently south towards Buena Vista Creek. Elevations range from 180 feet amsl to 220 feet amsl. The Project Site has been previously graded and crushed rock is present along the western boundary of the Project Site. No structures or roads exist onsite. The Project Site boundaries are bisected by Plaza Drive, bounded on the north by SR-78, to the east by the DMV facility and Thunder Drive, to the south by Buena Vista Creek and to the west by a shopping center. The Project Site is surrounded primarily by commercial and residential uses. The Project would be constructed in two (2) phases. The southern parcel, developed as Phase I, would provide a sales and administrative building, service building, private carwash, associated access drives, landscaped areas, presentation area, staging area, sales display area, and a customer and employee parking lot. The northern parcel would be developed as part of Phase II and would provide an additional sales display area. Site History Aerial Photographs and Historic Topographic Maps Historical uses of the Project Site were observed through aerial photographs of the Phase I Environmental Site Assessment (ESA) Report prepared by EnviroApplications, Inc. (Appendix B). Table 4.10-1 summarizes the series of photographs observed: Table 4.10-1 Aerial Photographs and Historic Uses Year Observations and Use 1928 The subject property and surrounding area appear to be open, hilly land in a rural, 1939 ranching setting. The currently existing roadways are not yet present. The subject 1946 property appears to be covered with brush and Buena Vista Creek is clearly visible to the 1953 south in its natural channel. CarMax Auto Superstore March 2021 Page 4.10-1 4.10 Hazards and Hazardous Materials The subject property still appears to be open, brush-covered land. State Route 78 has been constructed through the area to the north. Beyond the freeway further to the 1964 north are what appear to be a hospital campus and a drive-in movie theater. Thunder 1967 Drive (unpaved) is present along the eastern boundary of the subject property. By the 1970 time of the 1967 photo, the subject property and properties to the east appear to have been graded. The subject property appears to be vacant, graded land crossed by several trails. The homes in the residential neighborhood across Thunder Drive to the east have been 1979 constructed. Land along Buena Vista Creek to the south appears to have been graded to 1985 control flooding. The land to the west of the subject property is still vacant. By the 1985 photo the currently existing CA DMV facility is present to the east of the subject property. 1989 1990 1994 The subject and surrounding properties appear similar to the way they did during the 2005 reconnaissance visit for this ESA. 2009 2012 2016 Source: Phase I Environmental Site Assessment (Appendix B) Historic topographic U.S. Geological Survey (USGS) maps of the Project Site and surrounding area were analyzed and summarized in Table 4.10-2 below. No indicators of historic or current American Society of Testing and Materials (ASTM) recognized environmental conditions (RECs) were found. Table 4.10-2 Historic USGS Topographic Map Review Years Observations The subject property is depicted as vacant hillside land with SR-78 present to the north and 1996 Marron Canyon and Buena Vista Creek to the south. The surrounding area on the 1996 map is 2012 shaded pink, an indication of fully-developed land, with no features depicted.

Table 4.10-3 Historical Adjacent Property Uses Direction Summary of Historical Use North Originally open hillside land that became developed with the east-bound lanes of SR-78. East Originally open hillside land that became developed with, from north to south: the Oceanside DMV facility at 4005 Plaza Drive then Thunder Drive, followed by a residential neighborhood. South Always occupied by Buena Vista Creek, whose banks have undergone grading for flood control purposes. West Originally open hillside land that became developed with a large, multi-tenant shopping center with nearest address being 3841 Plaza Drive (a vacant shop for lease). Source: Phase I Environmental Site Assessment (Appendix B) Site Reconnaissance CarMax Auto Superstore March 2021 Page 4.10-2 4.10 Hazards and Hazardous Materials Site Reconnaissance Methodology A reconnaissance visit to the Project Site was conducted by EnviroApplications, Inc. on July 29, 2019 and the results are provided in the Phase Environmental Site Assessment Report (Appendix B). Methodology used to observe the subject property included the following: Traverse the central area of the subject property lots. Walk the reasonable accessible boundary areas of the subject property. Observe adjacent property areas from public thoroughfares. Hazardous Substances and Petroleum Products No hazardous substances or petroleum products; drums; strong pungent or noxious odors; pools of liquid, unidentified substance containers; or other observed evidence of hazardous substances or petroleum products were observed. Additionally, no underground storage tanks or aboveground storage tanks were observed. Exterior Observations No pits, ponds, or lagoons; stained soil or pavement; stressed vegetation; waste streams or waste collection areas; or solid waste disposal areas were observed onsite. No sources of wastewater; indication of storm water discharge; wells; septic systems; electrical power transmissions lines or other sources of elevated electromagnetic radiation were observed onsite. Two (2) mounds of fill soil located on the eastern portion of the property adjacent to Thunder Drive appear to consist of several hundred cubic yards of soil. While not qualifying as an ASTM REC, the mounds of fill soil were recommended for Phase II soil sampling and analysis to determine the source of the soil and its contents. The Summary of Berm Soil Sampling prepared by EnviroApplications, Inc. is provided as Appendix P. The results of the soil sampling are discussed below. No potential adverse environmental conditions were observed and no evidence of an ASTM REC or Historic REC (HREC) was observed on the Project Site based on the reconnaissance visit. Soil Sampling Results Following the initial reconnaissance visit, EnviroApllications, Inc. conducted a visit to collect soil samples from the mounds of fill soil located on the eastern portion of the property. Approximately 30 soil samples were collected from 10 locations at depths of approximately 1.5-, 3-, and 5-feet below the surface of the mounds. The 10 samples collected from the 3three-foot depth interval were submitted for laboratory analysis which screened for VOCs identified by U.S. EPA Method 8260B, including: Total Petroleum HydroCarbons (TPH) Extended Range by EPA Method 8015B, California Administrative Manual (CAM) 17 Metals by EPA Method 6010B, mercury by EPA Method 7471A, and organochlorine pesticides by EPA Method 8081A. Based on the results from these samples, the remaining 20 samples were not analyzed. VOCs, TPH in the gasoline fuel range (TPHg), and organochlorine pesticides were not detected in any of the soil samples collected. CarMax Auto Superstore March 2021 Page 4.10-3 4.10 Hazards and Hazardous Materials TPH in the diesel fuel range (TPHd) was detected in four of the samples collected, with detected concentrations ranging from 4.9 to 217.4 milligrams per kilogram (mg/kg). Total TPH was detected in eight of the soil samples collected, with concentrations detected ranging from 5.1 to 220 mg/kg. Concentrations of 12 of the 17 CAM metals were detected in the samples collected. Based on the results obtained, it was concluded that the mounds of fill soil are not considered a health risk for a commercial property with comparisons to the Department of Toxic Substances Control (DTSC) Screening Levels, and that the metal concentrations detected are within the range of typical elemental metal concentrations in soils of the western United States. Environmental Records Review A government agency database search report was obtained from Environmental Data Resources, Inc. (EDR) and found that the Project Site is not listed in the EDR Report nor do listings for nearby sites have the potential to impact the Project Site. The EDR Report did not indicate any oil or gas well sites located near the site and there are no existing or abandoned oil or gas wells or dry holes present on, or within a one-mile radius of the Project Site. A local and regional environmental records search was obtained for the Project Site and no records associated with the Project Site were found by the following agencies: DEH, OFD, Oceanside Building Department, Department of Toxic Substance Control, San Diego Water Board, SDAPCD and the Oceanside Water Utilities Department. The environmental records review did not result in an indication of a potential ASTM HREC or REC for the Project Site. Other Environmental Hazards Other environmental risks screened for in the search included lead-based paint, asbestos, flood zones, vapor encroachment, radon, dry cleaning operations, mold, and pesticides and other agricultural chemicals.
