A. As defined by the Shoreline Management Act (SMA) of 1971, “shorelines of the state” include certain waters plus their associated “shorelands.”

In the town of South Prairie, “shorelines of the state” include rivers and streams whose mean annual flow is 20 cubic feet per second (cfs) or greater.

“Shorelands” are minimally defined by the SMA as:

…those lands extending landward for two hundred feet in all directions as measured on a horizontal plane from the ordinary high-water mark; floodways and contiguous floodplain areas landward two hundred feet from such floodways; and all wetlands and river deltas associated with the streams, lakes, and tidal waters which are subject to the provisions of this chapter… (RCW 90.58.030)

B. Shoreline jurisdiction for the town of South Prairie consists of South Prairie Creek and its associated floodway, up to 200 feet of floodway-contiguous floodplain, and associated wetlands, and is shown on the maps included in Appendix A of this chapter. The maps only approximately identify or depict the lateral extent of shoreline jurisdiction. The actual lateral extent of the shoreline jurisdiction shall be determined on a case-by-case basis based on the location of the ordinary high-water mark (OHWM), floodway, floodplain, and presence of associated wetlands. In South Prairie, shoreline jurisdiction extends to land necessary for buffers to protect critical areas, pursuant to RCW 90.58.030(2)(d)(ii). Depictions of the shoreline jurisdiction are shown in Appendix D of this chapter.

C. In circumstances where shoreline jurisdiction does not include an entire parcel, only that portion of the parcel and any use, activity, or development on that portion of the parcel is subject to this shoreline master program. However, if a structure is situated on the border of shoreline jurisdiction, the entire structure is subject to this shoreline master program. The other portions of the parcel are still subject to all town planning and zoning ordinances. Town planning shall include concurrency planning with this SMP. [Ord. 580 Att. A § 3.1, 2019.]
