We are revising our existing Stormwater Code (SMC 22.800-22.808) and the associated Directors’ Rules. Our new rules will replace the current stormwater code and Directors' Rules, which are administered jointly by DPD and Seattle Public Utilities (SPU).
We just published Volumes 2, 4, and 5 and Appendices B and H of our Draft 2015 City of Seattle Stormwater Manual. They are available for your review on the Project Documents page. We want your feedback. Please visit the Get Involved page for information on how to provide comments. We'll accept comments through July 2014.

Our regulations will be equivalent to Ecology's 2012 Stormwater Manual and will address the following topics:
