dry land and irrigated farmed,particularly in pasture, vineyards, orchards and row crops for the Ir last several decades. Surrounding irrigation is provided from irrigation wells and the Central San Joaquin Irrigation District. Currently, there is an on-site irrigation well as denoted on the A.P.N. Map. There has been_discussion of usin this well for domestic purposes to serve the proposed new residence on the homesite parcel. Storm drainage flows from east of the homesite parcel to the south. Flood determination should be made by a licensed surveyor for determination of the proper house pad.and well elevation, if applicable. STANDARD PUBLIC ENVIRONMENTAL °RECORD SOURCES County, State and Federal environmental records were reviewed for sites which may have impacted the subject property. The databases accessed did not indicate a problem or potential problem with the subject site. Potential environmental impact from other facilities, whether commercial and/or residential within a one mile proximity to the subject site is unknown at this - time. It is conceivable that there may be groundwater impact at present or in the future, -particularly from nitrate due to agricultural inputs. As referenced, the subject property has been owned by the Van Vuren family for the past 51 years. The prior owner(s) is unknown. Since the operation and ownership of the subject property is well documented, previous property ownerships were not investigated:- There are two primary sources of information`which document and define past land use, although they are sometimes difficult to interpret. The first is the use of aerial photographs. Aerial photographs of the subject area in the 1970's from USDA Soil Maps illustrate the existing farm buildings such as the dairy barn near the southwest corner and center of the subject property. The second source of information can be found on USGS maps. A 1952 (Photo-revised 1968 and 1994)USGS quadrangle map for this area shows four;structures. There has been no photo revision of this USGS map since 1994. INFORMATION FROM SITE RECONNAISSANCE AND INTERVIEWS The following information was obtained visually and/or through an interview with Mr. Van _ Vuren on June 29, 2001: The subject property contains'no underground storage tanks (USTs) and apparently never has. There are two above ground storage tanks (ASTs) containing gasoline and one diesel AST. The two gas tanks are over soil and the diesel tank is over asphalt. There is also a propane tank used for heating and cooking. On-site, conventional septic systems with tanks and leachfield areas serves the residential and dairy barn structures. As noted on the attached Soil Survey map,'the subject property is composed of only one soil type: Hollenbeck silty clay (#173). Effluent percolation is expected to be slower in the silty clay soil where the residential structure is to be located. An intermittent hardpan stratum also exists. It is unknown at this time as to what type of septic system design will be installed, but it is assumed to be amleachfield with sumps or preferably seepage pits. vaffey Ag Research
