Project: Mint Plaza





Mint plaza

Location: San Francisco, California 

Sherwood’s work in converting the historic Old Mint in downtown San Francisco into a park and public plaza will set future development standards for green street design. Stormwater runoff from the plaza and surrounding rooftops is collected in a ‘rain garden’, and then filtered to a level far exceeding current City standards. Additional runoff is filtered through the plaza’s porous pavers into a grove of paper bark maples at the eastern end of the plaza, preventing virtually all plaza runoff from entering the City’s overloaded sewer system. By delaying, cleansing, and retaining runoff on site, these combined features work to protect the long-term health of the Bay, and propel San Francisco towards a more sustainable future.
