Shoreline Master Program

What Is It?
The Shoreline Master Program (23.60A) regulates development in the city’s shoreline environments to:
- Protect shoreline ecosystems
- Encourage water-dependent uses
- Provide for public access and enjoyment of the shorelines
- Preserve, and enhance, views of the water
Our ordinance requires that you:
- Obtain a shoreline substantial development permit, or a shoreline exemption, for any development in the Shoreline District
- Obtain a master use permit for any use or change of use in the Shoreline District
- Use best management practices in the shoreline to minimize and mitigate impacts on the aquatic environment
- Obtain and display a City-issued identification number for a floating residence (learn about the Floating Residence verification and registration process)

Recent Changes
We published a new Director's Rule (DR 9-2020), Verification of floating on-water residences, on July 30, 2020. The purpose of the Director's Rule is to clarify the application material required for verification of floating on-water residences and to establish an end date of September 30, 2020 for verification of any new floating on-water residences.
If you own a floating on-water residence that has not been verified, please fill out this Floating On-Water Residence Verification Form and follow the instructions in DR 9-2020 and Tip 229, Residential Use of a Floating Home, House Barge or Vessel.
We took public comments on the proposed new Director's Rule from June 22 through July 14, 2020. Notice of the proposed new Director's Rule was published in Seattle Services Portal on June 22, 2020. We responded by e-mail to those who provided comments.
