The purpose of the Stormwater Program is to efficiently utilize available assessment funding to reduce pollution of the storm water as it enters into our creeks and the bay, and to maintain public storm drain facilities. The program's activities are managed in accordance with National Pollution Discharge Elimination System (NPDES) Permit requirements enforced by the San Francisco Regional Water Quality Control Board and include performing field inspections (storm drain system, creeks, illicit connections), conducting educational and outreach activities (informational presentations, attending public events, coordination of storm drain stenciling), performing storm drain cleaning, regularly sweeping streets, and implementing new development/redevelopment stormwater controls.

New development

In February 2003, the San Francisco Bay Regional Water Quality Control Boards revised Provision “C.3” of the City's National Pollutant Discharge Elimination System (NPDES) permit governing discharges from the city's storm drain systems. The new permit provision is being implemented in phases beginning in 2004 through 2006.

The new “C.3” requirements are separate from-and in addition to-existing requirements for erosion and sediment control and for pollution prevention measures during construction.

New development and significant redevelopment project site designs should minimize the area of new roofs, pavements, and other impervious surfaces. Where feasible, pervious surfaces should be implemented so that stormwater runoff can percolate to the underlying soil. Stormwater runoff from impervious areas must be captured and treated before draining into the City's stormwater system and eventually into the Bay. The new permit regulations specify ways to calculate the required size and designs of appropriate stormwater treatment devices.

Projects may also be required to detain or infiltrate runoff so that peak flows and durations match pre-project conditions.

In addition, project applicants must prepare plans and execute agreements to insure that the stormwater treatment devices are operated and maintained in perpetuity.
