Nacimiento Water Project Image

The new 45-mile pipeline that delivers water from Lake Nacimiento to communities throughout San Luis Obispo County needed to pass a rigorous environmental and permitting process. The total project cost—including design, construction, environmental permitting, and right-of-way—was estimated at $176 million, the largest project the County has undertaken to date.

Working collaboratively with the client, local agencies, and a construction inspection team, ESA performed focused surveys for special-status plants and wildlife, conducted a thorough constraints and opportunities analysis, prepared supplemental environmental documentation under CEQA and NEPA, and developed specialized mitigation plans.

In coordination with project engineers, our team worked to minimize or avoid impacts to biological and cultural resources. We also participated in the preparation of environmental planning sheets corresponding to the construction drawings, visually representing all applicable environmental mitigations and permit conditions.

ESA worked to successfully negotiate agreements and secure permits and authorizations from the U.S. Corps of Engineers, California National Guard, and the State Historical Preservation Office. We prepared the Section 106 Technical Report, archeological testing plan, the archeological recovery and date treatment plan, and the Memorandum of Agreement between the Corps, California National Guard, and State Historic Preservation Office.
