Baker Beach Green Streets

SAN FRANCISCO, CA

< PROJECTS

The Baker Beach Green Street Project is one of eight Early Implementation Projects (EIPs) being constructed in San Francisco’s urban watersheds as part of the Sewer System Improvement Program. The primary objective of these projects is to demonstrate the efficacy of green infrastructure in reducing the peak flows and overall volume of stormwater that enter the city’s combined sewer system.

The Baker Beach project implements bioretention, infiltration galleries, and permeable pavement along a half mile of El Camino del Mar, Sea Cliff Avenue, and 25th Avenue North in the Sea Cliff neighborhood. The El Camino Del Mar project area consists of multi-functional green infrastructure nodes at three existing golf course path crossings and adds a new crossing and node in front of the Lands End Trailhead. Terraced bioretention bulbouts connected via subsurface infiltration galleries provide traffic calming and pedestrian safety while removing stormwater from the combined sewer system. Sea Cliff Avenue will be converted to permeable pavement for its full width between 25th and 26th Avenues, and a rain garden on Golden Gate National Recreation Area (GGNRA) land next to the 25th Avenue North cul-de-sac restores habitat with native plantings from the GGNRA nursery while adding management capacity to mitigate local CSDs and flooding.
