(1) Development regulations under the act are specific controls placed on development or land use activities by a county or city. Development regulations must be consistent with and implement comprehensive plans adopted pursuant to the act.

"Implement" in this context has a more affirmative meaning than merely "consistent." See WAC 365-196-210. "Implement" connotes not only a lack of conflict but also a sufficient scope to fully carry out the goals, policies, standards and directions contained in the comprehensive plan.

(2) When a county first becomes subject to the full planning requirements of RCW 36.70A.040, it must adopt development regulations designating interim urban growth areas as outlined under RCW 36.70A.110(5). The legislature specifically provided that the designation of interim urban growth areas shall be in the form of development regulations. Such interim designations shall generally precede the adoption of comprehensive plans.
