The Wastewater Utility Planning Division (UPD) recently implemented the Stormwater Control Plan (SCP) Review Fee to support SCP review services. New projects that submit their first Preliminary SCP after July 1st 2018 will be required to pay the fee for each Preliminary and Final SCP. To calculate your SCP Review Fee amount go to the SCP Review Fee Form (also available on our website under the SCP Resources webpage).
The UPD has released a version update of the Combined Sewer System BMP Sizing Calculator for Quantity Control (Version 2.2). All new SMO Projects that are submitting their initial Preliminary SCP on or after April 1st, 2019 must use Version 2.2 (also available on our website under the SCP Resources webpage).

Managing stormwater, which may otherwise wash pollutants into our waterways or overwhelm our sewer system, is critical to protecting water quality, wildlife, and public health. Like many California municipal agencies, the SFPUC administers a stormwater management program developed in accordance with the Clean Water Act. Effective May 22, 2010 and updated in 2016, the San Francisco Stormwater Management Ordinance (SMO) requires new and redevelopment projects to manage stormwater using green infrastructure (i.e. stormwater controls or best management practices) and to maintain that green infrastructure for the lifetime of the project.
Stormwater Management at a Glance
To manage stormwater that may otherwise wash pollutants into San Francisco waterways or overwhelm the City’s sewer system, and protect water quality, wildlife, and public health.
Who Must Comply?

SMR Frequently Asked Questions
Urban Watershed Management Program
The Stormwater Management Requirements and Design Guidelines (SMR) outlines the mandatory requirements for managing post-construction stormwater runoff and provides guidance on how to incorporate green infrastructure into site design.
Do the requirements apply to my project?
The SMR applies to the following project types:
new and redevelopment projects that create and/or replace ≥5,000 square feet of impervious surface in the separate and combined sewer areas; and
new and redevelopment projects that create and/or replace 2,500-5,000 square feet of impervious surface in separate sewer areas.
Activities that create or replace impervious surface include, but are not limited to, the construction, modification, conversion, or alteration of any building or structure and the creation or replacement of outdoor impervious surfaces such as parking areas, driveways, or private street areas.
The SMR does not apply to the following activities:
- pavement maintenance activities such as top-layer asphalt grinding and repaving within the existing footprint;
- replacement of existing sidewalks and streets dedicated to and accepted by the City;
- interior remodeling projects;
- exterior wall surface replacement; or
- utility repair work requiring trenching or excavation with in-kind surface replacement.
