Stormwater Requirements

Stormwater Pollution Prevention


Everywhere in the West Valley storm drains carry water from streets and yards to local creeks and on to San Francisco Bay - without wastewater treatment. Stormwater Pollution occurs when pollutants accumulate on streets and other surfaces and are washed off by rainfall or water. The pollutants flow into storm drains and from there directly into creeks and on to the Bay. Residents may contribute to stormwater pollution through regular everyday activities like driving and gardening. Commercial and industrial activities can also be sources of pollution.

Stormwater pollution is an important issue because it affects the health of local creeks and San Francisco Bay. Stormwater pollution reduces water quality.

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.
