(See Appendix A for reference maps and Appendix B for photos of the Property.) Property Setting& Location The area is in a rural part of western San Joaquin County about two miles east of Tracy. This area is in agricultural use,principally to raise row or grain crops and. The Property consists of 7 agricultural parcels that are contiguous, and have a total area of about 724 acres. The parcels are zoned AG-40. The Property occupies portions of Sections 9 and 10 of T3S, R6E, MDB&M. It is situated on the south side of Linne Road between Koster and Kasson Roads (see maps in Appendix A). The Property is served by a septic sewage system and a domestic water well situated near a farm building complex on parcel 38. The Banta Carbona Irrigation provides irrigation water. Stormwater is drained internally. Several pole-mounted utility transformers are on the Property. These appear to be the property of the electric utility company, PG&E. Physical Description In general, the Property consists of a large tract of fallow agricultural land. It apparently has been used to raise hay, row or grain crops. Irrigation pipelines provide irrigation water from the Banta-Carbona Irrigation District. Numerous standpipes provide evidence of the irrigation system. There are three drainage ponds on the Property. These are intended to collect excess irrigation water or stormwater runoff where a system of pumps permits recycling of the water to the fields. The fields are accessible by gravel and dirt roads around the periphery and several roads transect the land. (N�oed soil, stressed vegetation, unusual odors, or other evidence suggestive of a ous waste was noted on the Property except a small area near one of the drainage ponds which is marked by scattered yellow sulfur pellets lying on a dirt access road. Building Complex There is a single farm-building complex situated near the center of the Property. It includes two residences, and a residential garage. These appeared occupied and were not entered. Just west of the main house is an old pump house. It appears to have originally enclosed a domestic water well but today only a galvanized pressure tank lies within. The outdoor area around the residential buildings is landscaped. The existing domestic well some distance south of the pump house appears to be a replacement well. Near the new well is a large garage or equipment shed and an attached pole shed that also appears to have been intended to house equipment. At this time the building is entirely empty. South of this shed is a small Quonset but that is empty, but signage indicates it was 2937 Veneman Ave.,#B240 Geo-Phase Environmental Inc. Phone: (209)569-0293 Modesto,CA 95356 Fax: (209)569-0295
