35.05.080 Jurisdictional limits.
(1) The jurisdictional limits of this Program correspond to the following areas, which are defined in RCW 90.58.030 as shorelines of the State:
(a) All marine waters of the Strait of Juan de Fuca – the jurisdiction shall extend waterward from the ordinary high water mark to the State boundary with British Columbia; and
(b) All marine waters of the Pacific Ocean – the jurisdiction shall extend from the ordinary high water mark (excluding the area between the ordinary high water mark and extreme low water located in Olympic National Park) to the State boundary (the three-nautical-mile limit). The waters of the Pacific Ocean below (waterward of) the ordinary high water mark (except for the excluded areas in Olympic National Park), including designated marine sanctuaries and bedlands owned by the Washington State Department of Natural Resources, shall be subject to this Program even where the adjacent shorelands are under federal or Tribal ownership; and
(c) Reaches of rivers and streams where the mean annual flow is 20 cubic feet per second or greater; and
(d) Lakes and reservoirs 20 acres and larger in area; and
(e) Shorelands adjacent to the above water bodies subject to the provisions of this Program that include: those lands extending landward for 200 feet in all directions as measured on a horizontal plane from the ordinary high water mark; floodways and contiguous floodplain areas landward 200 feet from such floodways; all associated wetlands and river deltas; and the full extent of the mapped 100-year floodplain pursuant to RCW 90.58.030(2)(d)(i), as defined herein; and
(f) Shoreline jurisdiction also extends to all lands necessary for buffers to protect critical areas that are overlapping or otherwise coincident with the shoreline jurisdiction pursuant to RCW 90.58.030(2)(d)(ii).
(2) The portion of any individual parcel subject to shoreline jurisdiction shall be determined by the County on a case-by-case basis at the time shoreline development is proposed. The Administrator may require proponents of shoreline development proposals to provide site-specific information on the location or extent of the floodplain, the ordinary high water mark, and/or any associated wetlands or other critical areas to determine the extent of shoreline jurisdiction on a parcel-by-parcel basis.
(3) The County shall maintain a map, which shall be appended (see Exhibit A) to this Program, showing the general location and approximate extent of shorelines subject to this Program. The County shall also maintain a Geographic Information Systems database that depicts the coordinates for locating the upstream extent of shoreline jurisdiction (that is, the location where the mean annual stream flow is at least 20 cubic feet per second). The database shall also show the approximate location of the floodplain, floodway, wetlands, feeder bluffs, landslide hazard areas, channel migration zones and other features that may have a determinant effect on the jurisdictional boundaries of the Program. The database shall show features that have been identified by local, State and/or federal agencies using the best available information. The map and database shall be used for planning purposes only. The map and database shall be updated regularly as new information is made available and the public shall have access to the information upon request.
