The Director of Seattle Public Utilities is proposing rule DWW-430.1, Flow Control Requirements for Projects in Identified Public Combined Sewer Basins. The proposed draft and map exhibit for the SODO/Waterfront Basin are available on the project documents page. Written comments are due on or before May 14, 2015. See more on how to comment on the get involved page.
We will also host a public meeting on June 10, from 4:00 – 6:00 p.m. about the 2016 Stormwater Code and Manual Update.
In May 2014, we published the Draft 2015 City of Seattle Stormwater Manual, Volumes 1 through 5, and the appendices. They are available for your review on the project documents page.
Originally, we anticipated making all the changes at one time in 2015, as we had stated in handouts and at various public meetings throughout 2014. However, the Washington State Department of Ecology (Ecology) was delayed in sending their comments to us on our draft proposal. We received over 150 separate comments from Ecology in February 2015 that we're still addressing. Therefore, we are postponing most of our proposed Stormwater Code changes until January 2016.
In the meantime, in April 2015, the City Council and Mayor approved to revise three sections of the 2009 Stormwater Code (SMC 22.800-22.808) proposed to be effective by May 24, 2015. These changes are not the focus of Ecology's review. The changes are:
We will incorporate all other changes into our proposed 2016 Stormwater Code and Manual update, which will be effective in January 2016. Our new rules will replace the current Stormwater code and Directors' Rules, which are administered jointly by us and SPU.
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 2012 Stormwater Manual and will address the following topics:
