Wash. Rev. Code § 53.08.270
Before undertaking any such plan for the acquisition and operation of any park or recreational facility the proposed plan therefor shall be first submitted in writing to the director of the parks and recreation commission and to the governing body of any county or municipal park agency having jurisdiction in the area. The state director and/or such county or municipal park agency shall examine the port's proposed plan, and may disapprove such proposed plan if it is found to be in conflict with state or local park and recreation plans for the same area. If such proposed port plan is disapproved the port district shall not proceed further with such plan. If the state director or the governing body of the county or municipal agency does not respond in writing to the port within sixty days, it shall be deemed that approval has been granted.
