The official public review period for these documents was April 1 – May 16, 2020, but we are still interested in your comments. Visit the get involved page to find the template and instructions for submitting your feedback. We will hold another official comment period in the Fall/Winter of 2020.

We recently held two online public meetings on April 26 and May 6, 2020. If you missed them, watch our recording of the April 26 meeting and take a look at the PowerPoint.

Our proposed 2021 Stormwater Code and Manual update is scheduled to be effective in July 2021. Our new rules will replace the current Stormwater Code and Directors’ Rules, which are administered jointly by SDCI and Seattle Public Utilities (SPU). For more information, visit our background page.

As part of this process, we will be holding public meetings during three separate timeframes:

  • Spring of 2020 – Prior to submittal of the Draft Stormwater Code and Manual to Ecology (Completed)
  • Fall Winter of 2020 – After Ecology comments are received on Draft Stormwater Code and Manual
  • Spring 2021 – City Council Public Meeting
