The City of Seattle Stormwater Code and Manual became effective July 1, 2021. Please visit our Stormwater Code website as a great deal has changed with this update.
We know there will be a lot of questions about the changes, so we are hosting live question and answer sessions every Wednesday this August. These are small, informal sessions to answer any question that you have.
SDCI has also prepared online training materials that you can view at any time.
