Storm Water Requirements

Storm Water Pollution Prevention

As required by the Regional Water Quality Control Board, storm water management and pollution prevention measures are required for various types of projects. These measures manage water flows, improve the quality of storm water runoff, decrease flooding, protect the environment, and conserve water. Refer to Sunnyvale Municipal Code in Chapter 12.60.

Prior to issuance of building permits, projects that disturb over one acre or soil are required to file a Notice of Intent (NOI) and Storm Water Pollution Prevention Plan.

Note: New Low Impact Development (LID) requirements went into effect on December 1, 2011. Projects which did not recieve final discretionary approval by December 1, 2011 will be required to comply. Refer to the informational flyer prepared by the Santa Clara Valley Urban Runoff Pollution Prevention Program. The Storm Water Best Management Practices (BMP) Guidance Manual and Storm Water Data Sheet have been revised to reflect current changes.
