South San Joaquin County Water Supply Program Image

South San Joaquin Irrigation District's South County Water Supply Program is a series of phased projects designed to meet present and future water demands in California's Central Valley cities of Manteca, Escalon, Lathrop, and Tracy, as well as provide irrigation water for local agriculture. The $140 million water supply project in California's San Joaquin and Stanislaus counties is one of the program's phased projects designed to meet water supply needs.

ESA led the preparation of environmental documentation and permitting for the District's program. Our in-depth growth inducement analysis for the environmental impact report prevailed under litigation and set an early standard for growth inducement analyses for water supply projects. ESA collaborated with the design team in the development of several project components to minimize environmental impacts and streamline the permitting process. For example, potential environmental impacts and permitting requirements were significantly reduced by using a low-water control structure made of alternative construction materials; incorporating techniques that separate the raw water intake from recreational uses in the reservoir; and attaching the force main to a new pedestrian bridge to cross the San Joaquin River. ESA coordinated closely with state and federal agencies to obtain all required permits on time. We provided preconstruction surveys and construction monitoring, as well as cultural resources and hazardous materials investigations. The major water supply components of the program were constructed on time and within budget.

ESA worked collaboratively to reduce the environmental impacts and obtain required permits for a new $140 million complex water supply project to meet existing and future water demands for California's San Joaquin and Stanislaus counties.
