We posted an addendum to the Stormwater Code and Rule Update SEPA Environmental Checklist on June 25, 2015. We identified a need to propose related revisions to the 2012 Seattle Building Code, the 2012 Seattle Residential Code, and those Seattle Municipal Code titles regulating land use and grading to incorporate the new ecology requirements. These proposed revisions relate largely to the timing of how the Stormwater Code and Rule Update would be imposed (generally referred to as "applicability.") In addition, we identified two additional proposed revisions in the Stormwater Code and Rule Update.
Our proposed 2016 Stormwater Code and Manual update is scheduled to be effective in January 2016. Our new rules will replace the current Stormwater Code and Directors' Rules, which are administered jointly by us and Seattle Public Utilities (SPU). For more information, visit our background page.
We hosted a public meeting on June 10 about the 2016 Stormwater Code and Manual Update. The meeting notes are available on our get involved page. The draft documents of the 2016 Stormwater Code and other project applicability code changes are available for your review on the project documents page.
Our official public comment period on the draft 2016 Stormwater Code ended on June 30, 2015. However, we will continue to take comments until we send final recommendations to the Mayor for transmittal to the City Council. There is more information on how to comment on our get involved page.
There will be other opportunities this summer to provide public comment on the draft 2016 Stormwater Manual. We will also hold a public meeting related to the 2016 Stormwater Manual later this year.
Our stormwater code protects people, property, and the environment by controlling how rain water runs off of streets, buildings, and parking lots. Stormwater runoff can cause flooding, landslides, and erosion that can damage our homes, businesses, and property. Stormwater runoff carries oil and grease, fertilizers, pesticides and other toxic chemicals to our creeks, lakes, bays, rivers, and other waterways.
Our regulations will be equivalent to Ecology's 2014 Stormwater Manual and will address the following topics:
