The Chinatown Green Alley Project is a partnership between the SFPUC and San Francisco Public Works that will feature innovative green infrastructure technologies on Spofford Alley in the City’s historic Chinatown neighborhood. The project includes flow-through planters and streetscape features to naturally capture stormwater runoff before it enters the sewer system.  Green infrastructure uses the natural process of plants and soil to filter, clean, and infiltrate stormwater. During heavy rains, stormwater can overwhelm the City’s combined sewer system and contribute to neighborhood flooding and combined sewer discharges into the San Francisco Bay and Pacific Ocean. Green infrastructure not only helps clean and reduce the amount of stormwater in the sewer system, but also uses rainwater as a resource to provide multiple community benefits.

The Chinatown Green Alley is a part of the Sewer System Improvement Program (SSIP), a 20-year, multi-billion dollar citywide investment required to upgrade our aging sewer system.
