Jurisdictional Delineation Report ii Biological Technical Report CarMax Auto Superstore EXECUTIVE SUMMARY This Biological Technical Report (BTR) was prepared for the proposed CarMax Auto Superstore (proposed project) located in the City of Oceanside. It documents the existing biological conditions within and adjacent to the approximately 14.915-acre survey area (subsequently refered to as the ‘proposed project survey area’), which includes the approximately 10.981 acres within two undeveloped parcels (subsequently refered to as the ‘proposed project site’) and an approximately 3.935-acre, 50-foot survey buffer surrounding these parcels (subsequently refered to as the ’50-foot survey buffer”). The information provided in this report is based on the results of a general biological survey conducted on July 22, 2019; a focused jurisdictional delineation conducted on August 29, 2019; and subsequent focused surveys for sensitive plant species, fairy shrimp, coastal California gnatcatcher (Polioptila californica californica), and least Bell’s vireo (Vireo bellii pusillus).
