Newcomb Avenue Project
Newcomb Avenue, now recognized as the greenest street in San Francisco, was completed in December 2011. The project replaced a nearly 100% impervious streetscape with LID elements, such as permeable pavement, sidewalk landscaping, trees, and stormwater planters.
- Improved water quality through treatment of stormwater by the project's block-long implementation of LID components
- Contribute to the understanding of LID BMP design effectiveness: The project tests the effectiveness of various BMPs and their ability to retain stormwater runoff.
- Serve as a model for future projects in the San Francisco Bay Area: Information gathered from ongoing monitoring of this project will inform future LID projects in San Francisco and other areas around the Bay. In order to comply with new stormwater permit provisions requiring implementation of LID to protect local streams, creeks and the Bay, municipalities need project relevant information to help determine what is cost-effective in their jurisdictions.
- Neighborhood renewal by street beautification: The project's amenities, including new plants and trees, traffic calming features, and sidewalk design will foster community pride.
