The goal of the SDG is to protect and enhance the function of the sewer system and the quality of
receiving water by:
• managing stormwater runoff from development that would otherwise mobilize pollutants
and degrade local water quality;
• reducing stormwater run-off rates, volume, and nonpoint source pollution whenever
possible, through stormwater management controls, and
• ensuring that these management controls are safe and properly maintained.

Projects subject to the SDG submit a Stormwater Control Plan to demonstrate compliance with the
stormwater management requirements. To date, over 230 projects have complied or are in the
process of complying with the SDG – the 100 Final Approved Stormwater Control Plans indicates that
these approved projects are complete or under construction! Some fun facts:

Wastewater Enterprise's 100th Stormwater Control Plan Approved
By: Wastewater Enterprise 2/9/2016
The SFPUC’s Urban Watershed Management Program (UWMP) celebrated the signing of the 100th
Final Approved Stormwater Control Plan last week! Since January 2010, the UWMP has been
implementing the Stormwater Design Guidelines (SDG), which require new and redevelopment
projects that disturb more than 5,000 square feet of ground surface to manage their stormwater on-
site, using green infrastructure technologies such as rainwater harvesting, bioretention, or permeable
• When complete, these projects will manage stormwater from 156 acres – that’s roughly 62
• These projects are estimated to remove over 14 million gallons of stormwater from the
sewer system each year – that’s equivalent to 21 Olympic sized swimming pools!
