Shoreline Master Program
What Is It?
The Shoreline Master Program (23.60A) regulates development on the City’s shorelines to:
- Protect shoreline ecosystems
- Respond to pollution discharges into bodies of water
- Encourage water-dependent uses
- Provide for maximum public use and enjoyment of the shorelines
- Preserve, enhance, and increase views of and access to the water
Our ordinance requires that you:
- Obtain a shoreline substantial development permit, or an exemption from that permit, 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 residence floating on water (learn about the Floating Residence verification process)
For emergency spill response: contact Department of Ecology’s 24-hour hotline at 1-800-OILS-911. To find out if the spill is also a shoreline violation, call (206) 615-0808.
For pollution discharges into lakes, creeks, and public storm drains: contact Seattle Public Utilities. To find out if the spill is also a shoreline violation, call (206) 615-0808.
