Analysis Background In its application, the Landmark Lathrop Group indicated that a Minor Subdivision application has been submitted to the Community Development Department to subdivide the property to create a 70-acre parcel and a 92-acre parcel. However, at this time, no such application has been submitted to the County. Operational Characteristics Approximately three feet of topsoil will be removed and stockpiled adjacent to and south of the quarry site. After the excavation is completed, the topsoil will be replaced, and the site will be planted in alfalfa. Overburden will be stockpiled adjacent to the quarry site on the east and respread. This material will be for sale as general fill material and will be used for contouring the land prior to replacing the topsoil. Sand will be removed from the site as it is excavated. There are no plans for sand stockpiles. The sand will not be processed on the site. General Plan/Zoning The site is designated Open Space-Resource Conservation on the General Plan and is zoned AG-40. The State Division of Mines and Geology identifies the site as MRZ-2 Mineral Resources Zone. A quarry may be conditionally permitted in the AG-40 zone with an approved Quarry Excavation Permit if the area to be excavated is designated Resource Conservation and the State Mines and Geology Board has identified the area as construction aggregate deposits of regional significance. This site meets these requirements. City of Lathrop The City of Lathrop indicated that this project is consistent with the Lathrop General Plan designation of RCO (Resource Conservation/Extraction) for the mining of mineral resources. Screening and Landscaping Because State Route 120 is elevated well above the project site, screening of the site from State Route 120 is not practical. Screening the site from Madruga Road is not recommended because the only traffic on Madruga Road at that location will be quarry traffic. (This exception frorn the screening requirement is made pursuant to Section 9-1415.3(s) of the Development Title.) Reclamation Plan After the excavation is completed, the three feet of topsoil that was removed and stockpiled will be replaced, and the site will be planted with alfalfa. The maximum slope at the change of grade will be 4:1. Traffic Trucks will access and exit the site via Madruga Road and Guthmiller Road. From Guthmiller Road, trucks exiting the site will either enter State Route 120 or Yosemite Avenue. Omni Means prepared a traffic study dated January 4, 2001. Omni Means assumes that at least 90 percent of the traffic will be via State Route 120 rather than Yosemite Road. The traffic study estimated that the project will generate approximately 100 outbound and 100 inbound trucks per day. The study determined that the roads and intersections contain QX-00-1\Roorda San Joaquin County Page 3 Community Development
