Shoreline Master Program Update

Shoreline Master Program
The City of Enumclaw (city) has developed its 1st Shoreline Master Program (SMP), as required under the Washington State Shoreline Management Act (SMA).
Shoreline Management Act
The SMA was adopted in 1972 “to prevent the inherent harm in an uncoordinated and piecemeal development of the state’s shorelines,” and has 3 broad policies:
  1. 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…”
  2. Protect shoreline natural resources, including “…the land and its vegetation and wildlife, and the water of the state and their aquatic life…”
  3. 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.”
Shoreline Jurisdiction
Under the Shoreline Management Act (WAC 173-18 and WAC 173-20), the shoreline jurisdiction includes uplands, which are 200 feet landward of the ordinary high water mark (OHWM) of waters that have been designated as shorelines of the state, and associated floodplains and wetlands, as defined below.

Shorelines of the State
All marine shorelines and shorelines of all other streams or rivers having a mean annual flow of 20 CFS or greater and lakes with a surface area 20 acres or greater.

Shorelands
  • Those lands extending landward for 200 ft. in all directions as measured on a horizontal plane from the OHWM
  • Floodways and contiguous floodplain areas landward 200 ft. from such floodways
  • All associated wetlands and river deltas
Associated Wetlands
Wetlands that are in proximity to and either influence or are influenced by tidal waters or a lake or stream subject to the SMA. These are typically identified as wetlands that physically extend into the shoreline jurisdiction, or wetlands that are functionally related to the shorelines of the state.

Shorelines of the State Present Within the City
Within the city and its associated Urban Growth Area (UGA), 2 streams are considered “shorelines of the state,” Boise Creek and Newaukum Creek. Both creeks begin in the Cascade foothills above the Enumclaw plateau. Newaukum Creek drains into the Green River, which is the largest tributary stream to the Duwamish River, the largest river in Watershed Resource Inventory Area (WRIA) 9. Boise Creek drains into the White River, which becomes the Puyallup River, and flows into Puget Sound in the City of Tacoma, WRIA 10.
