(1) For shorelines of the state, the goals and policies of the Shoreline Management Act as set forth under RCW 90.58.020 are added as one of the goals of this chapter as set forth under RCW 36.70A.020 without creating an order of priority among the fourteen goals. The goals and policies of a shoreline master program for a county or city approved under chapter 90.58 RCW shall be considered an element of the county or city's comprehensive plan. All other portions of the shoreline master program for a county or city adopted under chapter 90.58 RCW, including use regulations, shall be considered a part of the county or city's development regulations.

(2) The shoreline master program shall be adopted pursuant to the procedures under chapter 90.58 RCW rather than the goals, policies, and procedures set forth in chapter 36.70A RCW for the adoption of a comprehensive plan or development regulations.

(3)(a) The policies, goals, and provisions of chapter 90.58 RCW and applicable guidelines shall be the sole basis for determining compliance of a shoreline master program with chapter 36.70A RCW except as the shoreline master program is required to comply with the internal consistency provisions of RCW 36.70A.070, 36.70A.040(4), 35.63.125, and 35A.63.105.

(b) Except as otherwise provided in (c) of this subsection, development regulations adopted under chapter 36.70A RCW to protect critical areas within shorelines of the state apply within shorelines of the state until the department of ecology approves one of the following: A comprehensive master program update, as defined under RCW 90.58.030; a segment of a master program relating to critical areas, as provided under RCW 90.58.090; or a new or amended master program approved by the department of ecology on or after March 1, 2002, as provided under RCW 90.58.080. The adoption or update of development regulations to protect critical areas under chapter 36.70A RCW prior to department of ecology approval of a master program update as provided in this subsection is not a comprehensive or segment update to the master program.

(c)(i) Until the department of ecology approves a master program or segment of a master program as provided in (b) of this subsection, a use or structure legally located within shorelines of the state that was established or vested on or before the effective date of the local government's development regulations to protect critical areas may continue as a conforming use and may be redeveloped or modified if:

(A) The redevelopment or modification is consistent with the local government's master program; and

(B) The local government determines that the proposed redevelopment or modification will result in no net loss of shoreline ecological functions. The local government may waive this requirement if the redevelopment or modification is consistent with the master program and the local government's development regulations to protect critical areas.

(ii) For purposes of (c) of this subsection, an agricultural activity that does not expand the area being used for the agricultural activity is not a redevelopment or modification. "Agricultural activity," as used in (c) of this subsection, has the same meaning as defined under RCW 90.58.065.

(d) Upon department of ecology approval of a shoreline master program or critical area segment of a shoreline master program, critical areas within shorelines of the state are protected under chapter 90.58 RCW and are not subject to the procedural and substantive requirements of chapter 36.70A RCW, except as provided in subsection (6) of this section. Nothing in chapter 321, Laws of 2003 or the act is intended to affect whether or to what extent agricultural activities, as defined under RCW 90.58.065, are subject to chapter 36.70A RCW.

(e) The provisions under RCW 36.70A.172 shall not apply to the adoption or subsequent amendment of a local government's shoreline master program and shall not be used to determine compliance of a local government's shoreline master program with chapter 90.58 RCW and applicable guidelines. Nothing in this section; however, is intended to limit or change the quality of information to be applied in protecting critical areas within shorelines of the state, as required under chapter 90.58 RCW and applicable guidelines.

(4) Shoreline master programs shall provide a level of protection to critical areas located within shorelines of the state that assures no net loss of shoreline ecological functions necessary to sustain shoreline natural resources as defined by department of ecology guidelines adopted pursuant to RCW 90.58.060.

(5) Shorelines of the state shall not be considered critical areas under chapter 36.70A RCW except to the extent that specific areas located within shorelines of the state qualify for critical area designation based on the definition of critical areas provided under RCW 36.70A.030(5) and have been designated as such by a local government pursuant to RCW 36.70A.060(2).

(6) If a local jurisdiction's master program does not include land necessary for buffers for critical areas that occur within shorelines of the state, as authorized under RCW 90.58.030 (2)(f), then the local jurisdiction shall continue to regulate those critical areas and their required buffers pursuant to RCW 36.70A.060(2).

(7) County participation in the voluntary stewardship program does not change applicability of the Shoreline Management Act, or requirements of local shoreline master programs.

(a) As required by RCW 90.58.065, shoreline master programs shall not limit or modify existing and ongoing agricultural activities occurring on agricultural lands.

(b) Master programs shall include provisions addressing new agricultural activities on land not meeting the definition of agricultural land, conversion of agricultural lands to other uses, and other development on agricultural land that does not meet the definition of agricultural activities.
