What is a Shoreline Master Program (SMP)?

A SMP is a comprehensive shoreline land-use plan that:

•       Protects shoreline processes;

•       Promotes public access;

•       Accommodates all appropriate shoreline uses; and

•       Balances public and private interests.

What geographic area is covered by the SMP?

The SMP jurisdiction applies at minimum to the following shorelines of the state [RCW 90.58.030]:

•       All marine waters.

•       Segments of streams where the mean annual flow is more than 20 cubic feet per second.

•       Lakes and reservoirs 20 acres and greater in area.

•       Shorelands adjacent to these water bodies.  The minimum shoreline jurisdiction for shorelands is the greater of the following:

o    Lands extending landward 200 feet in all directions from the OHWM, including 200 feet in all directions from the OHWM at the 20 cubic feet per second point.  (Shoreline jurisdiction would extend above the 20 cubic feet per second point.)

o    The floodway plus the contiguous floodplain 200 feet landward of the floodway.

o    Associated wetlands and river deltas.
