The San Francisco's Public Utilities Commission's (SFPUC) Urban Watershed Management Program has completed the Open House series, which outlined the updates to the Stormwater Design Guidelines that are anticipated to become effective in Early 2016.
Click here to review the Open House presentation that contains information on the updates to the Stormwater Design Guidelines.
Below are a few of the major changes:
- A new name! The Stormwater Design Guidelines will be called the Stormwater Management Requirements (SMR) once the changes become effective in Early 2016.
- The threshold at which project must comply with the SMR has been redefined. In the 2010 Guidelines, projects disturbing 5,000 square feet or more of the ground surface were subject to the requirements. In the revision, the threshold for Large Projects has been revised to projects creating and/or replacing 5,000 square feet or more of impervious surface.
- Small Projects are regulated under the 2015 SMR. Small Projects are those that create and/or replace 2,500-5,000 square feet of impervious surface in the Separate Sewer Area ONLY. Projects of this size were not regulated in the 2010 Guidelines.
The San Francisco Public Utilities Commission’s (SFPUC) Urban Watershed Management Program (UWMP) has been working over the past year to implement regulatory-driven updates to the 2010 Stormwater Design Guidelines (Guidelines). We are pleased to present you with the Final Draft of the newly named Stormwater Management Requirements and Design Guidelines (SMR) and the associated appendices for your review. Some of the major changes include:
- The threshold at which projects must comply with the SMR has been redefined. In the 2010 Guidelines, projects disturbing 5,000 square feet or more of the ground surface were subject to the requirements. In the revision, projects creating and/or replacing 5,000 square feet or more of impervious surface are subject to the requirements.
- Small Projects are regulated in separate sewer areas under the 2015 SMR. Small Projects (those creating and/or replacing 2,500-5,000 square feet of impervious surface) must implement one or more Site Design Measure(s). Projects of this size were not regulated in the 2010 Guidelines.
The team would appreciate feedback on the technical content of the text, its general clarity, and the overall completeness of the document.

- Minimize impervious surfaces, which would allow more rainfall to soak into the ground
- Reduce the volume and intensity of storm water runoff, which would reduce flows that end up in the receiving waters
- Convey and treat storm water runoff using landscape features and other “green” systems to provide treatment to the pollutants in the runoff
