The San Francisco Stormwater Design Guidelines (Guidelines) describe the requirements for stormwater management in San Francisco and give developers the tools to achieve compliance. The Guidelines were adopted by the San Francisco Public Utilities Commission on January 12, 2010. The Stormwater Management Ordinance is effective May 22, 2010.
Amendments to the 2010 Stormwater Design Guidelines:
The UWMP acknowledges that some projects subject to the Stormwater Management Ordinance have more challenging site conditions than others. With this in mind, we have developed the Modified Compliance Program to allow development projects with proven site challenges and limitations to modify the standard stormwater performance measures set by the SDG, therefore creating a more fair and flexible standard. The Modified Compliance Program:
- Applies only to projects in the Combined Sewer System (CSS)
- Evaluates site limitations including: high groundwater, shallow depth to bedrock, poorly infiltrating soils, contamination, and zero lot-line projects
- Assesses project potential for non-potable demand
- Modifies volume and peak rate reduction requirements based site-specific constraints
- Is not available for projects with already approved Preliminary or Final SCPs
- Modified Compliance Application (July 2014)
To have your project evaluated for Modified Compliance a completed Modified Compliance Application must be submitted to the SDG Review Team at email@example.com prior to submitting a Preliminary SCP.

The SDG Review Team suggests that each project schedule a pre-application meeting early during the planning and team building process. Early coordination with the SDG Review Team will minimize design challenges and project schedule delays.
In order to streamline the scheduling of pre-application meetings, the SDG Project Review Team is implementing open office hours that will be available exclusively for project proponents to schedule a 60 minute pre-application meeting. Henceforth, the SDG Project Review team will ONLY be available for Pre-Application meetings Tuesdays from 1-4pm and Thursdays 10am-1pm. Please contact the SDG Project Review Team at firstname.lastname@example.org
to schedule a meeting.
NEW! Annual Self-Certification Inspections
As outlined in the Guidelines, it is the responsibility of the property owner or a designated party to perform an Annual Self-Certification inspection of all stormwater Best Management Practices (BMPs) for constructed projects. These Self-Certifications are required to ensure proper maintenance is being performed and the functionality of BMPs is sustained.
The property owner or a designated party must complete and submit an Annual Self-Certification Checklist for each installed BMP type. Below you will find the Annual Self-Certification Checklist and the associated Instructions for each BMP type.
Submit completed Annual Self-Certification Checklists electronically to email@example.com
OR by mail to

Is my project in the Combined or Separate Sewer System?
The Stormwater Design Guidelines performance measure requirements vary depending on whether your project is located in an area served by the Combined Sewer or Separate Sewer. Use the map below to determine which type of sewer system your project is served by.
