Stormwater Management

Stormwater Management

Santa Clara County manages stormwater through the National Pollutant Discharge Elimination System (NPDES), which in California, is overseen by Regional Water Quality Control Boards (RWQCBs). The San Francisco Bay RWQCB (Region 2) regulates waters discharging to San Francisco Bay, and The Central Coast RWQCB (Region 3) regulates waters discharging to the Monterey Bay.

Region 2: San Francisco Bay

The northern portion of the County drains to the San Francisco Bay and is under the jurisdiction of the San Francisco Bay Regional Water Quality Control Board. This portion of the County has been under a NPDES Municipal Stormwater Phase I Permit since 1990. The County of Santa Clara participates in the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) to address the many of the requirements of the Municipal Regional (Phase I) NPDES Permit.

​Region 3: Central Coast

The Southern portion of the County drains to the Pajaro River and Monterey Bay and is under the jurisdiction of the Central Coast Regional Water Quality Control Board. This portion of the County obtained a NPDES Municipal Stormwater Phase II permit in 2010. The County of Santa Clara works jointly with the City of Morgan Hill and the City of Gilroy to address the requirements.

The County of Santa Clara, the City of Morgan Hill and the City of Gilroy meet monthly to discuss the implementation of the Phase II permit. These meetings are held on the second Monday of each month at 10:00 in the morning at the City of Morgan Hill Public Works Department at 100 Edes Court Morgan Hill, CA. If you would like to receive more information about these monthly meetings please contact the Clean Water Program at (408) 282-3165.
