Shoreline Master Programs

Shoreline Master Programs (SMPs) are local land-use policies and regulations that guide use of Washington shorelines. SMPs apply to both public and private uses for Washington's more than 28,000 miles of lake, stream, wetland, and marine shorelines. They protect natural resources for future generations, provide for public access to public waters and shores, and plan for water-dependent uses.

We review and approve SMPs for local governments and provide guidance and technical assistance to help governments develop their SMPs. We work with local governments to help create and update these SMPs to ensure they comply with the state Shoreline Management Act and state Shoreline Master Program Guidelines. More than 260 cities and counties have SMPs. They are an important tool for wise management of these precious and valuable areas.

Managing the use and development of state shorelines is important. It helps preserve what people in Washington value while protecting life and property. Sharing and caring for state and local shorelines is everyone’s responsibility.
