The Washington State Shoreline Management Act (also referred to in this document as SMA or the Act) was passed by the legislature in 1971 and adopted by a vote of Washington’s citizens in a 1972 referendum (RCW 90.58). The goal of the Shoreline Management Act is "to prevent the inherent harm in an uncoordinated and piecemeal development of the state’s shorelines." The Act also recognizes that "shorelines are among the most valuable and fragile" of the state’s resources.
The Act provides for the management and protection of the state’s shoreline resources by requiring planning for their reasonable and appropriate use. The area regulated under the Act includes lands within two hundred (200) feet of designated shorelines as well as certain wetlands, river deltas, floodways and floodplains associated with such shorelines.
The SMA establishes a balance of authority between local and state governments. Cities and counties have the primary review responsibility for development along their shorelines, and the state (through the Washington State Department of Ecology) has authority to review local master programs and local shoreline development permit decisions.
