k4 KLEINFELDER L will eventually have a winery and tasting room respectively. We understand that there are no existing septic systems on the property. Please see the attached site plan for the existing site layout. We understand that this study is being required by the San Joaquin County 6- Environmental Health Department(SJCEHD) as part of the proposed parcel split. ` 2. PRESENT AND PAST USE Based on information provided to us by Mr. Bokisch, we understand that the site has been and is currently being used for dryland cattle grazing. No other past site use is readily available. We understand that the 5-acre vineyard was installed in 2003. 3. SEPTIC PERMITS AND PERFORMANCE L There were no SJCEHD septic permits on file for the subject property or those parcels adjacent to the subject property. i According to Mr. Bokisch, there are no septic systems on the subject property and he has no knowledge of any repairs needed on septic systems in the immediate project area. Based on the lack of permits on file, either any existing unpermitted septic systems in the project area are tr performing well with no repairs required or there are few/no septic systems on the adjacent parcels. �- 4. GROUNDWATER During the time of our investigation, groundwater was not encountered. Lines of Equal Depth to Groundwater contour maps published in groundwater reports prepared by the San Joaquin County Flood Control and Water Conservation District show groundwater levels in the project area ranging from about 130 to 140 feet below ground surface from Spring 1981 to Spring 1999. The maps do not extend to the project site every year. Based on Equal Elevation of Groundwater maps, the general groundwater gradient is from east to west. Local gradient ` variations may be present due to well usage. Groundwater use at the site has been non-existent prior to vineyard installation. Future use L would include vineyard irrigation and residential use for the proposed single-family homes. We do not know of any existing and/or potential groundwater contamination issues in the L project vicinity. There are no existing gas stations or dairies adjacent to the property, although a set of railroad tracks have been removed along the northern boundary of the property. L Railroad tracks often had pipelines or utilities running adjacent to them in the railroad right-of- way, however we have no knowledge of whether any of these were present along these particular tracks. We understand that a surface and subsurface contamination report yielded no findings of significant contamination on the property.
