This report presents the results of a cultural and historical resource inventory conducted within the Area of Potential Effect (APE) for the proposed project. This study was completed in compliance with the California Environmental Quality Act (CEQA). The City of San Marcos is the lead agency for CEQA review. This study included a literature and records search, a pedestrian survey of the project APE, and recommendations for future work. No cultural resources had been previously recorded within the APE. No archaeological sites were identified within the project APE as a result of the pedestrian survey. The proposed project will not result in adverse impacts to known prehistoric or historical resources. K-8 Elementary School, Park Grading and Infrastructure Improvement Project v 1. Introduction 1. INTRODUCTION PROJECT DESCRIPTION The City of San Marcos (City) is the lead agency for the proposed grading and infrastructure construction to develop an approximately 15 acre rough graded pad for construction of a 1,500 student K-8 school site, grading of an approximately 35 acre active park site, and associated infrastructure improvements as described below. The project is located within the southwestern portion of the Heart of the City Specific Plan. The project site property is bounded by Twin Oaks Valley Road on the east, the previously reclaimed areas of Hanson to the north, undeveloped land on the west, and the Vallecitos Water District (VWD) reservoir (future South Lake Park) to the south, in the Barham/Discovery Hills neighborhood. The project site coincides with the southern portion of the former Hanson mining site. The eastern and northern portions of the site are disturbed from past aggregate mining activities and the remainder of the site is vegetated and undeveloped. School - Grading for a school pad is part of the proposed project. The San Marcos Unified School District will conduct a separate review under the California Environmental Quality Act to address the impacts of school construction and operation. Park – Grading of approximately 35 acres is proposed as a future active use park. The City will conduct a separate review under the California Environmental Quality Act to address the impacts of park construction and operation. Spillway/Trail – The proposed spillway modification will redirect the spillway from the future school pad. A trail linkage from South Lake Park to the school site will also be included. Roadway Improvements - The proposed project includes the extension of South Village Drive (600 lineal feet) west of Twin Oaks Valley, and an access road (875 lineal feet) located south of the school site to provide VWD maintenance access to Southlake, a public access and future parking lot to future South Lake Park, and a secondary public access to the new private road entry to the school. Grading – Two grading scenarios are considered for the project and are based upon the height of the proposed school pad. The lower school pad scenario will require approximately 912,000 cubic yards (cy) of cut, with future roads requiring approximately 530,000 cy of fill. The remaining 382,000 cy would be placed on the future park site. No offsite export or import will be required under this K-8 Elementary School, Park Grading and Infrastructure Improvement Project 1 1. Introduction scenario; however, there will be approximately 38,200 truck loads to move the material internally (assuming 10 cy capacity truck). The higher school pad scenario will require approximately 330,000 cy of cut with future roads requiring approximately 530,000 cy of fill. The remaining 200,000 cy will be come from the future park site. No offsite export or import will be required under this scenario; however, there will be approximately 20,000 truck trips to move the material internally. Due to the properties of the bedrock, a rock crusher will be used during the grading operation. The rock crusher will require a Conditional Use Permit. The purpose of the cultural resources survey was to aid in compliance with the California Environmental Quality Act (CEQA). STUDY METHODS This study included a literature and records search with the California Historical Resources Information System (CHRIS) and with the Sacred Lands File of the Native American Heritage Commission (NAHC), and a pedestrian survey of the project APE. The record search and survey was originally completed for the 163-acre Rancho Coronado project area in March 2012. The City of San Marcos has since subdivided the Rancho Coronado into two separate projects. This report
