Washington Sensible Shorelines Association

Who is WSSA?

Washington Sensible Shorelines Association was created in 2008 by citizens who wanted to make sure property owners were treated fairly under a Shoreline Master Program that Bellevue was in the process of revising in 2008.  WSSA advocates for a balance between the property owner’s rights, responsibilities, and evolving environmental regulations.

Our ongoing role, and the purpose of this website, is to keep shoreline property owners informed of shoreline issues as they arise, and of changes to regulatory policy pertaining to our shoreline areas.

About this website

Located on this website is information pertaining to the Washington State shorelines.  The menu located in the banner at the top of this page will guide you to research that will help you understand the implications of these regulations and assist you in making decisions regarding your property.

Why should you be interested?

Do you own property within 200 feet of the waterfront?  Under Washington State’s Shoreline Management Act, all cities with lakes larger than 1000 acres are required to update their Shoreline Master Program (SMP) every seven years. These regulations prescribe what you can and cannot do on your shoreline property. The most recent update of Bellevue’s SMP was finalized in 2018. WSSA is a resource for navigating the multi-agency shoreline programs, which will change over time and likely become more restrictive, not less.  Knowing this, are you interested?
