Closest available station to Site was selected. <br /> • Reduced Rainfall: For this method, rainfall levels from the closest rain station <br /> are multiplied by a percentage based on a reasonable assumption from the <br /> literature. Because the Hantzsche and Finnemore model utilized a value of <br /> approximately 75 percent rainfall as the rate of recharge from percolating waters <br /> in the Chico area, that value is applied to local rainfall in the project area. The <br /> San Joaquin County Environmental Health Department recommended this <br /> approach in 2017, with the understanding that it would better characterize <br /> recharge within the County (personal communication with Rodney Estrada, Lead <br /> REHS, January 6, 2017). <br /> As discussed above, the Lodi station (045032), the closest station to the Site, <br /> reports the average total annual precipitation from January 1893 through January <br /> 2015 to be 17.24 inches (Table 3). Assuming 75 percent of this precipitation <br /> percolates to the aquifer, the rate of recharge from percolating waters is <br /> calculated to be an average of 12.93 inches per year. <br /> LOGE 1903 Page 11 <br />
