Stormwater Pollution Prevention

Stormwater Systems

Throughout the West Valley, storm drains carry water from streets and yards to local creeks and on to the San Francisco Bay - without wastewater treatment.

Stormwater pollution occurs when pollutants accumulate on streets or other surfaces, and they are washed off by rainfall or water. The pollutants flow into storm drains, then directly into creeks and on to the bay. Stormwater pollution reduces water quality and affects the health of local creeks and the bay.

Residents contribute to stormwater pollution through everyday activities, like driving and gardening. Commercial and industrial activities can also be sources of pollution.

Requirements for Development

Conditions of approval for development projects include the installation and maintenance of Best Management Practices (BMP's) for site design and storm water treatment, which must be designed per approved numeric sizing criteria. General guidance on the selection and implementation of BMP's and Storm Water Pollution Prevention Plans can be found on the California Storm Water Quality Association website and at the Santa Clara Urban Runoff Pollution Prevention Program website.
