The official public review period for these documents was April 1 – May 16, 2020, but we are still interested in your comments.

The Department of Ecology is requiring Seattle to update our current codes with additional stormwater control regulations as a condition of our NPDES permit. To meet these requirements, we are revising our existing Stormwater Code (SMC 22.800-22.808) and the associated Stormwater Manual (Directors’ Rule 17-2017). These new rules will replace the current drainage control code and Directors’ Rules which are administered jointly by SDCI and Seattle Public Utilities.
