San Francisco Public Utilities Commission Water System Improvement Program

The San Francisco Public Utilities Commission (SFPUC) has been providing water supply to the California Bay Area for nearly 100 years and now serves more than 2.5 million customers. To address aging infrastructure, earthquake susceptibility, increasingly stringent water quality regulations, and projected deficits in dependable water supply, voters approved a $4.3 billion bond measure to fund a capital improvement program for the regional water system.

ESA prepared the program environmental impact report (PEIR) for the SFPUC's Water System Improvement Program (WSIP). WSIP would improve the service area water supply and delivery through the year 2030 with a number of system improvements, operational changes, and a supplemental water supply. The PEIR evaluates the environmental effects of the proposed changes in water supply, including growth-inducing impacts, as well as the general environmental effects of implementing proposed facility improvements through more than two dozen projects. ESA's team examined the potential effects of the WSIP on water and associated biological resources from the Sierra Nevada mountains to the Bay Area over a wide range of hydrologic conditions.

ESA prepared an award-winning eight-volume PEIR to provide a comprehensive analysis within the SFPUC's stringent schedule requirements. The Draft PEIR was completed within 18 months from receipt of the conceptual program description. This project received the National Environmental Excellence Award for Environmental Leadership by the National Association of Environmental Professionals and the first-ever Good Government Award for Planning and Infrastructure by the San Francisco Planning + Urban Research Association.
