Shoreline Management Home

Washington’s Shoreline Management Act (SMA) was adopted by the public in a 1972 referendum “to prevent the inherent harm in an uncoordinated and piecemeal development of the state’s shorelines.” The SMA has three broad policies:

  • Encourage water-dependent uses: "uses shall be preferred which are consistent with control of pollution and prevention of damage to the natural environment, or are unique to or dependent upon use of the states' shorelines...”
  • Protect shoreline natural resources, including "...the land and its vegetation and wildlife, and the water of the state and their aquatic life..."
  • Promote public access: “the public’s opportunity to enjoy the physical and aesthetic qualities of natural shorelines of the state shall be preserved to the greatest extent feasible consistent with the overall best interest of the state and the people generally."

State-local partnership

The SMA is administered through a cooperative program between local governments and Ecology:

The Act places a strong emphasis on public participation in developing local shoreline programs and in the local permit process.

Shoreline Master Programs

Ecology's adoption of new shoreline master program (SMP) guidelines in 2003 initiated a new generation of shoreline planning in Washington. The guidelines were developed as part of a year-long negotiated settlement that also led to adoption of shoreline legislation (effective July 2003) that established a new schedule for updating SMPs, and a biennial appropriation of $2 million to fund local SMP development.

NEW! - 10/14/2009 Ecology has developed a set of “frequently asked questions” about shoreline master programs. We will be adding more information to our list to answer issues and other questions as local governments and Ecology move through the update process.  

Ecology administers an SMP Grants Program that provides funding for local jurisdictions to undertake comprehensive SMP updates. The next grant cycle will open in the spring of 2009.
