The Growth Management Act (GMA) requires that an adopted Comprehensive Plan shall be subject to continuing review and evaluation and that any amendment or revision to the Comprehensive Plan conform to the requirements of Chapter 36.70A RCW, and that any change to development regulations or official controls is consistent with and implement the Comprehensive Plan (RCW 36.70A.130(2)). Additionally, RCW 36.70A.130(2) specifically requires that the County establish procedures whereby proposed amendments or revisions of the Comprehensive Plan are considered by the County Council no more frequently than once every year except that amendments may be considered more frequently under the following circumstances: (1) the initial adoption of a subarea plan; (2) adoption or amendment of a shoreline master program; and (3) the amendment of the capital facilities element. Proposals must also be considered by the County Council concurrently so the cumulative effect of the various proposals can be ascertained. However, Plan amendments that conform to the GMA may be adopted whenever an emergency exists or to resolve an appeal of the comprehensive plan with a growth management hearings board or the court. RCW 36.70A.120 further requires that the County shall perform its activities and make capital budget decisions in conformity with the Comprehensive Plan.
