Laguna Mountain Environmental conducted an archaeological survey on an approximately 15-acre study area, in the La Jolla Natural Open Space Park area on Mount Soledad above La Jolla in the City of San Diego. As part of the field survey, an archaeological and historical research program consisting of a cultural resources records search, literature review, and examination of historic maps was conducted. Laguna Mountain also conducted an archaeological testing program at site CA-SDI-20843 within the project impact area in order to evaluate the significance of this resource (Pigniolo 2014a). An archaeological and Native American monitoring program of geotechnical testing work for the La Jolla View Reservoir Project was also conducted. Monitoring occurred during bore hole augering at seven locations for the project. The cultural resource survey, testing, and monitoring studies were initially conducted in accordance with the California Environmental Quality Act and the City of San Diego Land Development Code and Historical Resources Guidelines. The City of San Diego will serve as lead agency for the project and local CEQA compliance. The project includes funding from the State Revolving Fund (SRF). The State Water Resources Control Board will serve as Lead Agency for Federal environmental review in accordance with the National Environmental Policy Act (NEPA) and compliance with Section 106 under the National Historic Preservation Act (NHPA). This current report consolidates earlier CEQA studies and provides information necessary for Section 106 compliance. Records Search - The records search was initially conducted at the South Coastal Information Center at San Diego State University on March 20, 2013. The record search was updated as part on September 14, 2015 for the CEQA document, and subsequently updated on October 22, 2018. The record search concluded that the project area had not been previously surveyed prior to the current studies, but that at least 216 cultural resource investigations have been conducted within one mile of the project area. One hundred and thirty cultural resources have been identified through previous research within the one-mile radius of the project. Two prehistoric cultural resources had been identified within or adjacent to the study area: P-37-029299 (CA-SDI-18740) and P-37-029797 (CA-SDI-19057). Both of these sites represent modern day redeposited prehistoric cultural material from other locations. Survey - The survey was conducted by Andrew R. Pigniolo, MA, on March 15, 2013. Mr. Gabe Kitchen of Red Tail Monitoring and Research, Inc. served as Native American monitor. Due to the steep slopes and dense brush, two survey methodologies were used. Most of the study area was surveyed in standard 10 to 15 m transect intervals.
