Existing Septic Tank Usage in the Vicinity To estimate the septic system usage in the area, our office counted septic systems that exist within approximately one square mile surrounding the property. Air photo imagery from Google Earth was used. Each building cluster on the photo was assumed to have one septic system. Using this method, it is estimated that at least 275 septic systems per square mile are located in the immediate vicinity of the Site. The area north of the Site that is part of the City of Tracy is presumed to have municipal sewer service and was excluded from the count. The Site is located within a large residential neighborhood. Agricultural land and the Tracy Defense Depot are located approximately one-third of a mile east of the Site.
