A decommissioned municipal reservoir provided not only an ideal location for a new 4.25-acre park with views of the Golden Gate Bridge and San Francisco Bay, but also an opportunity to ease demand on the city’s water supply.
Ramy Azar, project engineer for Sherwood Design Engineers, the project’s civil engineer, says the original plan to create a lawn atop the reservoir would have required 70,000 cu yd of imported fill to achieve the desired sloped grade. Incorporating a new stormwater collection, treatment and reuse system for non-potable uses, Azar says, “reduced required fill needs by more than half, while maintaining the reservoir’s historic use as a body for water collection.”
