The project is located north of McCauley Lane, South of Buena Vista Way, and between Valley and Monroe streets in the city of Carlsbad, San Diego County, California (Attachment 1). The project includes Assessor's Parcel Number (APN) 156- 220-0 I and is located in Section 31 (Township 11 South, Range 4 West) and Section 6 (Township 12 South, Range 4 West) on the USGS 7.5-minute San Luis Rey, California topographic quadrangle map (Attachment 2). The Yada Family Farm Subdivision Project included the construction of 12 detached, single-family homes, an access road and cul-de-sac (Yada P lace), and associated improvements and utilities on 3.79 acres of the 4.57-acre property (Attachment 3). Cultural Resources: The subj ect property was previously surveyed on November 29, 2015 by ASM Affiliates for the presence of cultural resources (Castells 2016). The fie ld investigation included an intensive pedestrian survey of the project, a Native American Heritage Commission Sacred Lands File search, and a records search from the South Coastal Information Center at San Diego State Un iversity. No cultura l resources were identified within the subject property as a result of the 2015 investigation. 1-+010 fbwa_y Road, Suite A, fbwa_y, CA 92o6+; Phone (858) 679-8218 or ('/51) 681-9950; l'i>x (858) 679-9896; www.bfsa-ca.com ~U5incM office, 1+678 ibex Court, San Diego, CA 92129; Phone (858) +8+-0915; rax (858) +8+-0988 Brian F. Smilh and As.wdalcx. /11,,. -Pagl! 2 Geology and Paleontology: Geologically, the project is underlain by Pleistocene "older paralic deposits" that overlie the 120,000-year-old Nestor Terrace equivalent. Paralic deposits include any of a variety of sediments deposited in a coastal or near-coastal depositional environment and they may, or may not, be fossiliferous. These are labeled as Qop2-4 on Attachment 4 ( after Kennedy and Tan 2005 [Geologic map of the Oceanside 30' x 60' quadrangle, California: California Geological Survey, Regional Geologic Map Series, 1: 100,000 scale, Map no. 2, sheet 1]). Pleistocene marine sediments (i.e., paralic deposits) along the San Diego County coast are typically assigned a High paleontological sensitivity (cf Demere and Walsh 1993 [Paleontological Resources, County of San Diego]; Stephenson et al. 2009 [County of San Diego, Guidelines for Deten;nining Significance, Paleontological Resources]), which typically requires that any earth- disturbing activities affecting them would require paleontological monitoring. Monitoring and Results: The Yada Family Farm Subdivision Project has been used agriculturally since at least the 1930s, and therefore, the surface of the site had been cleared and disked prior to grading. Archaeological and paleontological monitoring of the project were conducted from September 24 to October 12, 2018. Monitoring consisted of closely observing areas being excavated by earthmoving equipment. No fossils or fossiliferous sediments of any sort were observed during monitoring, nor were any observed in the sidewalls of the cuts or in any of the temporary spoil or stockpiles generated during these activities. Similarly, no cultural resources of any sort were observed dming monitoring. Based upon this investigation, no significant archaeological or paleontological resources are regarded as having been either lost or otherwise adversely affected by grading and earthmoving activities concomitant with site preparation for the Yada Family Farm Subdivision Project. The City of Carlsbad's mitigation requirements for archaeological and paleontological monitoring are considered to have been satisfactorily completed. Thank you for the opportunity to provide archaeological and paleontological services on this project. If you have any questions, please feel free to contact us at our Poway office.
