1 KLE/NF..MIN <br /> "M.1..Fighfblufiuu <br /> 8 GROUNDWATER <br /> ' Groundwater was encountered at a depth of about 30 feet below existing site grade in a boring <br /> drilled for a geotechnical investigation prepared by Kleinfelder at the site in October 2015. Lines <br /> ' of Equal Depth to Groundwater contour maps (2011 to 2015) published online by the California <br /> Department of Water Resources (DWR) show groundwater levels in the project area ranging from <br /> about 20 to 25 feet below ground surface. Lines of Equal Elevation of Groundwater contour maps <br /> ' (2011 to 2015) published online by DWR show the groundwater gradient in the project area is <br /> generally to the north to northeast. Local gradient variations may occur due to well usage. <br /> ' The existing concentrations of nitrate as NO3 in the groundwater at the site are unknown because <br /> a water supply well is not located within the parcel. Groundwater is not currently used at the site, <br /> nor is it anticipated to be used in the near future for existing or proposed facilities within the parcel. <br /> ' We do not know of any existing and/or potential groundwater contamination issues in the project <br /> vicinity. There are no existing dairies adjacent to the property. Other septic tank/leach field <br /> ' systems in the project area are probably the largest contributors of nitrogen to groundwater in the <br /> project vicinity. <br /> 1 <br /> ' 20162869.001A/ST0161138644 Page 8 of 15 April 19, 2016 <br /> ©2016 Kleinfelder <br /> 1 <br />
