Draft 2021 Stormwater Code and Manual Comments
Thank you to everyone that commented on the draft versions of the 2021 Stormwater Code and Manual. There were a lot of great comments that helped shape the Code and Manual updates. The comment periods are now closed. The final Code and Manual are now posted on the Project Documents page.
Public Meetings
We've held the following online public meetings to describe the proposed changes:
- Spring of 2020 (Completed): Prior to submittal of the Draft Stormwater Code and Manual to Ecology 2 online public meetings were held 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!
- November 12, 2020 (Completed): This meeting focused on changes to the Stormwater Code, Volume 1 of the Stormwater Manual, and Appendix B (Additional Submittal Requirements), and Appendix I (Landscape Management Plan and Integrated Pest Management). If you missed this meeting, watch the recording and take a look at the PowerPoint. Please note: the graphs of the Peak Flow Control Standard changes on pages 37 and 38 were incorrect in the meeting presentation and are corrected in the files posted here.
- January 28, 2021 (Completed): This meeting, associated with public review period #3, focused on changes to the full revised draft of the Stormwater Manual (all volumes and appendices) since the spring 2020 public review period. In addition, it covered associated changes to the Grading Code and introduced the new SPU public drainage system Director's Rule. If you missed this meeting, watch our recording and take a look at the PowerPoint. (Note: the PowerPoint presentation also includes topics covered in November.)
Important Note: during the public meeting, we were asked if the information on a SDCI preliminary assessment report would "vest" a project based on the information provided (e.g. approved point of discharge, flow control requirements, etc.). We would like to clarify that preliminary assessment reports or preliminary applications do not vest any projects to a certain code or director's rule. SDCI permit applications will not be vested to the 2016 Stormwater Code and associated rules unless there is a complete permit application (i.e. the full permit submittal is screened, accepted, and fees paid) prior to July 1, 2021.
