�J Analysis Background The proposed site contains irrigated row crops such as corn, tomatoes, pumpkins, oats and alfalfa. The excavated material from the proposed site will be transported and processed at the applicant's existing quarry and processing facility(QX-91-3)which is located on the adjacent parcels north of the proposed project site. The processing facility was originally approved by the Planning Commission on July 18, 1991, as part of a quarry that would operate for a thirty (30)year period with an expiration date of July 28, 2021. On February 1, 2001'the Planning Commission approved a Revision of Approved Actions for QX-91-3. The Revision added eighteen (18)years with a new expiration date of 2039 and final reclamation by 2041. Excavation The quarry operation will consist of a combination of quarrying for the top soil (overburden) and dredging for the sand. The Reclamation and Site Plan submitted to the Community Development Department indicates `S that the maximum excavation depth will be 60 feet. The excavation will extend into the groundwater which is �Aofound 5 to 15 feet below ground surface. However, drinking water wells in the area obtain their water at depths greater than 100 feet as indicated by the California Regional Water Quality Control Board, Central Valiey Region findings Order No. 91-217. Therefore excavation will not affect drinking water. Excavation will not occur with 300 feet of the landside levee, or near any wetland, pond, stream, river or floodway, and there will be no in-stream mining on the site. Plant and Animals The Natural Diversity Database does not list any rare, endangered, or threatened species or habitat located on or near the site. The project site however, is subject to the San Joaquin County Multi-Species Habitat Conservation &Open Space Plan (SJMSCP) as determined by the San Joaquin Council of Governments , (SJCOG).The applicants have indicated that they will participate in the SJMSCP, which with satisfy the Fish and Wildlife Service and San Joaquin Council of Governments. Slopes/Contours The contour created by the excavation will be the final contour required in the Development Title. Cuts will not create interim slopes that need backfilling during reclamation. Slopes above the water table (the area out of the water) to the bottom of the excavation (area under the water)will not exceed 2 feet horizontal to 1 foot vertical. Final contour will be created as the excavation progresses. Slopes will be excavated to finish grade. Reclamation Reclamation will occur concurrently with the mining operation as a single phase as the final reclamation is the creation of a lake for aquaculture, and areas not in the process of excavation will remain under agricultural cultivation. Each year as more material is excavated less area will be farmed, and the lake will grow larger. Eventually only the setback areas as shown on the Reclamation Site Plan will remain available for crop farming. The final reclamation to aquaculture will be completed by stocking the lake with channel catfish or other marketable fish.
