Regardless of the method used to identify the floodway, the floodway shall not include those lands that can reasonably be expected to be protected from flood waters by flood control devices maintained by or maintained under license from the federal government, the state, or a political subdivision of the state;

(c) "Ordinary high water mark" on all lakes, streams, and tidal water is that mark that will be found by examining the bed and banks and ascertaining where the presence and action of waters are so common and usual, and so long continued in all ordinary years, as to mark upon the soil a character distinct from that of the abutting upland, in respect to vegetation as that condition exists on June 1, 1971, as it may naturally change thereafter, or as it may change thereafter in accordance with permits issued by a local government or the department: PROVIDED, That in any area where the ordinary high water mark cannot be found, the ordinary high water mark adjoining salt water shall be the line of mean higher high tide and the ordinary high water mark adjoining fresh water shall be the line of mean high water;

(d) "Shorelands" or "shoreland areas" means 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; the same to be designated as to location by the department of ecology.

(i) Any county or city may determine that portion of a one-hundred-year-flood plain to be included in its master program as long as such portion includes, as a minimum, the floodway and the adjacent land extending landward two hundred feet therefrom.

(ii) Any city or county may also include in its master program land necessary for buffers for critical areas, as defined in chapter 36.70A RCW, that occur within shorelines of the state, provided that forest practices regulated under chapter 76.09 RCW, except conversions to nonforestland use, on lands subject to the provisions of this subsection (2)(d)(ii) are not subject to additional regulations under this chapter;

Intent—Retroactive application—Effective date—2010 c 107: See notes following RCW 36.70A.480.

Finding—Intent—2003 c 321: "(1) The legislature finds that the final decision and order in Everett Shorelines Coalition v. City of Everett and Washington State Department of Ecology, Case No. 02-3-0009c, issued on January 9, 2003, by the central Puget Sound growth management hearings board was a case of first impression interpreting the addition of the shoreline management act into the growth management act, and that the board considered the appeal and issued its final order and decision without the benefit of shorelines guidelines to provide guidance on the implementation of the shoreline management act and the adoption of shoreline master programs.

(2) This act is intended to affirm the legislature's intent that:

(a) The shoreline management act be read, interpreted, applied, and implemented as a whole consistent with decisions of the shoreline[s] hearings board and Washington courts prior to the decision of the central Puget Sound growth management hearings board in Everett Shorelines Coalition v. City of Everett and Washington State Department of Ecology;

(b) The goals of the growth management act, including the goals and policies of the shoreline management act, set forth in RCW 36.70A.020 and included in RCW 36.70A.020 by RCW 36.70A.480, continue to be listed without an order of priority; and

(c) Shorelines of statewide significance may include critical areas as defined by RCW 36.70A.030(5), but that shorelines of statewide significance are not critical areas simply because they are shorelines of statewide significance.

(3) The legislature intends that critical areas within the jurisdiction of the shoreline management act shall be governed by the shoreline management act and that critical areas outside the jurisdiction of the shoreline management act shall be governed by the growth management act. The legislature further intends that the quality of information currently required by the shoreline management act to be applied to the protection of critical areas within shorelines of the state shall not be limited or changed by the provisions of the growth management act." [ 2003 c 321 s 1.]

Finding—Intent—2002 c 230: "The legislature finds that the dollar threshold for what constitutes substantial development under the shoreline management act has not been changed since 1986. The legislature recognizes that the effects of inflation have brought in many activities under the jurisdiction of chapter 90.58 RCW that would have been exempted under its original provisions. It is the intent of the legislature to modify the current dollar threshold for what constitutes substantial development under the shoreline management act, and to have this threshold readjusted on a five-year basis." [ 2002 c 230 s 1.]

Effective date—1995 c 255: See RCW 17.26.901.

Severability—1986 c 292: "If any provision of this act or its application to any person or circumstance is held invalid, the remainder of the act or the application of the provision to other persons or circumstances is not affected." [ 1986 c 292 s 5.]

Intent—1980 c 2; 1979 ex.s. c 84: "The legislature finds that high tides and hurricane force winds on February 13, 1979, caused conditions resulting in the catastrophic destruction of the Hood Canal bridge on state route 104, a state highway on the federal-aid system; and, as a consequence, the state of Washington has sustained a sudden and complete failure of a major segment of highway system with a disastrous impact on transportation services between the counties of Washington's Olympic peninsula and the remainder of the state. The governor has by proclamation found that these conditions constitute an emergency. To minimize the economic loss and hardship to residents of the Puget Sound and Olympic peninsula regions, it is the intent of 1979 ex.s. c 84 to authorize the department of transportation to undertake immediately all necessary actions to restore interim transportation services across Hood Canal and Puget Sound and upon the Kitsap and Olympic peninsulas and to design and reconstruct a permanent bridge at the site of the original Hood Canal bridge. The department of transportation is directed to proceed with such actions in an environmentally responsible manner that would meet the substantive objectives of the state environmental policy act and the shorelines management act, and shall consult with the department of ecology in the planning process. The exemptions from the state environmental policy act and the shorelines management act contained in RCW 43.21C.032 and 90.58.030 are intended to approve and ratify the timely actions of the department of transportation taken and to be taken to restore interim transportation services and to reconstruct a permanent Hood Canal bridge without procedural delays." [ 1980 c 2 s 1; 1979 ex.s. c 84 s 1.]
