Based on a review of the San Joaquin County Flood Control and Water Conservation <br /> District Groundwater Report, Lines of Equal Depth to Groundwater Spring and Fall 2015 to 2016, <br /> depth to groundwater was reported between approximately 80 to 100 feet. Based on a review of <br /> the sources, depth to groundwater is anticipated to be greater than 80 feet bgs. <br /> Responsive r Resourceful ■ Reliable 6 <br />
