On-Site Septic Permit History Live Oak searched the septic system permits on file at the San Joaquin County Environmental Health Department for the Site address; no permits were identified. • Existing Septic Tank Usage in the Vicinity To estimate the existing septic system usage in the area, our office counted septic systems located within approximately one square mile surrounding the property. Aerial imagery from Google Earth was used. Each building cluster on the photograph was assumed to have one septic system. Using this method, it is estimated that 300 or more septic systems per square mile are present in the immediate vicinity of the Site. Closely-spaced County residential neighborhoods located to the north, west, and south of the Site were included in the estimate, though it is unclear whether all the houses utilize septic systems. The general area consists of residential neighborhoods and agricultural land. The Tracy Defense Distribution Depot is located approximately 1,000 feet to the northeast.
