SUMMARY This survey report documents Jones & Stokes' efforts to identify cultural resources within the proposed DeSilva Gates Construction sand and gravel mine site, located in southwestern San Joaquin County(Figure 1). This investigation was conducted in compliance with the California Environmental Quality Act(CEQA)requirements for inventory and evaluation of cultural resources. Additionally, local regulations regarding the treatment of cultural resources as outlined in the San Joaquin County General Plan(General Plan 1992)will ` be followed. San Joaquin County is the lead agency under CEQA. The tasks completed to accomplish the inventory and evaluation included prefield research, consultation with Native Americans and other interested parties, archival research, archaeological field surveys, and preparation of this report. No cultural resources were identified as a result of this study. PROJECT DESCRIPTION r The project area is located in southwestern San Joaquin County, south of the city of Tracy. The project area is approximately 220 acres and proposed operations on the site would include the installation and operation of a rock plant, asphalt and concrete batch plants, and a recycling plant. The total production of mined aggregate and overburden over the 40-year life of the project is estimated by DeSilva Gates to be 30 million tons. All overburden will be used for reclamation; an estimated 20-million tons of aggregate will be marketed. The average mine production of marketed material is estimated to be 750,000 tons annually. The project would be excavated and reclaimed in four phases using two pits—the South Pit(approximately 40-acres) v and the North Pit (approximately 115-acres). .. REGULATORY SETTING State Regulations California Environmental Quality Act CEQA requires that public or private projects financed or approved by public agencies assess the effects of the project on historical resources. Historical resources are defined as buildings, sites, structures, objects, or districts, each of which may have historical, architectural, archaeological, cultural, or scientific significance. CEQA requires that, if the project would result in an effect that may cause a substantial adverse change in the significance of a historical resource, alternative plans or mitigation measures must be considered; only significant historical resources need to be addressed, however. Therefore, before the development of mitigation DeSilva Gates Quarry Project,San Joaquin County Cultural Resources Inventory Report Community Development Department November 1005 1 AS 05-105 60
