Project Documents

We just published these draft documents for the 2015 City of Seattle Stormwater Manual, and we are interested in your feedback. Please email your comments to stormwatercode@seattle.gov through July 2014.

The following documents outline the summary of changes we made to the volumes listed above. Our regulations must be equivalent to Ecology's NPDES 2012 Stormwater Manual.
