Residents want alternatives studied in San Francisco aquifer plan

About 30 people braved the cold and rain Wednesday night to tell the San Francisco Planning Department what it should cover in an environmental study of a plan to pump millions of gallons of water per day from under the west side of the city.

The most common requests from speakers were for a clear explanation of alternatives to the Groundwater Supply Project, and for the city to lay out where an equivalent water supply would come from if the planned extraction of groundwater had to be interrupted or abandoned for any reason.

Joan Girardot asked planners to include clear alternatives to the GSP in the environmental study, including alternatives that would include not building the system at all. Girardot also asked for an assessment of the current state of the Westside Basin Aquifer, to act as a baseline reference against which to compare future impacts on the underground reservoir. In addition, she asked for the study to explain what measures the city would take to mitigate the inconvenience that neighborhood residents might experience during construction.

Dan Murphy of the Golden Gate Audubon Society asked planners to provide an “adaptive management plan” in case the pumping proved to have a negative effect on wildlife or the health of lakes connected to the aquifer.

The Planning Department will continue to collect written comments until Jan. 30.

City plans new network of wells on west side of San Francisco

San Francisco is planning a groundwater well system that would draw millions of gallons a day from new and enlarged wells on the west side of the city, mixing the water with existing supplies for residents of western San Francisco to drink.

The proposed project is part of the San Francisco Public Utilities Commission’s efforts to improve the safety and reliability of local water supplies.

Proposed Groundwater System Project

Six wells are planned as part of the project, from Lake Merced in the south to the northern edge of Golden Gate Park. Some new wells would be dug, while others would be modified to boost their pumping capacity. In addition, pipelines would be laid under neighborhood streets to get water from the wells to the recently renovated Sunset Reservoir at Ortega Street and 24th Avenue.

Neighborhood residents and businesses can weigh in on what kinds of environmental impacts the city should study before it launches the well project, starting tonight at a meeting in Golden Gate Park.

The Planning Department will hold a “scoping meeting” on the San Francisco Groundwater Supply Project at 7 p.m. Jan. 20 at the Golden Gate Park Senior Center, 6101 Fulton St. at 37th Avenue. People will be able to tell the city what subjects it should study in its environmental-impact report on the project and how deep its analysis should be.

The department also will accept comments from the public in writing at the meeting or via mail, fax or email through Jan. 30.

Written comments should be sent to by mail to the San Francisco Planning Department, Attn: Bill Wycko, Environmental Review Officer, San Francisco Groundwater Supply Project Scoping Comments, 1650 Mission St., Suite 400, San Francisco, CA 94103; by fax to (415) 558-6409; or by e-mail to jamie.dean@sfgov.org.
