Seattle’s stormwater code protects people, property and the environment by controlling how rain water runs off of streets, buildings, and parking lots. Stormwater is the main source for pollutants in our creeks, lakes, bays and other waterways.
Urban areas that collect stormwater runoff in municipal separate storm sewers and discharge it to surface waters must have a permit under the federal Clean Water Act. As part of Seattle’s permit, we are required to update our stormwater code and our regulations must be equivalent to Ecology’s NPDES 2012 Stormwater Manual.
To meet these requirements, we are revising our existing Stormwater Code (SMC 22.800-22.808) and the associated Directors’ Rules.
To review the initial draft stormwater regulations and/or participate in a survey, please visit our Stormwater Code & Rules Update website. This is an initial and informal review period. After receiving equivalency from Ecology, the final drafts will be available for formal public review and comments. We anticipate this to take place in winter 2015.
You can also submit comments and join the Stormwater Code listserv by sending an email to email@example.com. Comments will be accepted through July 2014.
