INTRODUCTION Landmark Lathrop Group, L.L.C. is proposing the excavation of mineral resources (sand) from a portion of a 162-acre parcel (APN No. 241-030-03) located southeast of the Interstate 5 and Highway 120 interchange in San Joaquin County, California. A separate parcel map application has been filed with the County that will create two parcels from the 162-acre parcel: one of±70-acres and one of±92- acres. The proposed quarry will be located on the 70-acre parcel and will encompass approximately 60- acres of which 19-acres will be excavated to a minimum depth of approximately 14 feet below the existing grade with the remaining 41 acres excavated to a depth of 11 feet below the existing grade. Side slopes into the quarry will be 4:1 or flatter. Stockpiles of topsoil and overburden will be placed on both the 70-acre and 92-acre parcels. After completion of the mineral extraction, the property will be reclaimed for agricultural uses (Alfalfa). This application supersedes a previous pre-application submitted for the quarry in February 2000. The previous application proposed a greater depth of excavation and a reclamation plan consisting of a golf course and aqua range. Many of the comments on the pre-application made by the reviewing agencies were directed towards the potential impacts to the groundwater and/or other impacts as a result of the envisioned public use. As suggested by the County, the Use Permit application has been separated from the quarry application. This application, therefore, significantly simplifies the proposed quarry operation and reclamation plan by reducing the quarry excavation depth to above the shallow groundwater elevation and reclaiming the property to agricultural use. The General Plan designation for the property is OSRC (Open Space and Resource Conservation). The property is zoned AG40 with a mineral resource overlay of MRZ-2. The recovery of mineral resources is consistent with this zoning designation. DESCRIPTION OF ENVIRONMENTAL SETTING GENERAL Figure 1 shows the relationship of public roadways with the site. Public access to the property is provided via County maintained Madruga Road. Madruga Road intersects with Guthmiller Road immediately adjacent to the State Route 120/ Guthmiller-Yosemite Blvd Interchange. As also shown in Figure 1, the subject parcel is bounded by State Route 120 to the north, Union Pacific Railroad to the south, the San Joaquin River and undeveloped parcels to the west and industrially zoned and developed parcels to the east. The property is presently being used as an almond orchard. This orchard is approaching the end of its economic 20-year life cycle and is slated for removal. There are several large electrical transmission towers and lines located to the south of the quarry site. There is an existing irrigation well located near the northern portion of the western property line. GEOLOGY AND SEISMICITY Neil O. Anderson and Associates prepared a Soil and Mineral Classification Investigation in August of 1996. A copy of this investigation is contained in Appendix A of this application. As stated in the investigation, a majority of the property lies within Mineral Resource Zone 2. Surficial deposits of minerals are Holocene in age (0 to 11,000 years) and consist of undivided alluvial-flood plain deposits of sand, silt and clay. A contact exists on the site between the Holocene deposits and older Pleistocene 'r materials of the Modesto Formation. This formation is composed of fluvial (river) deposits of silt and Surface Mining Application Page 1 Landmark Lathrop, L.L.C.
