The department of ecology shall adopt rules concerning the floodplain management activities of a county, city, or town that are adequate to protect or preclude flood damage to structures, works, and improvements, including the restriction of land uses within a river's meander belt or floodway to only flood-compatible uses. Whenever the department has approved county, city, and town floodplain management activities, as a condition of receiving an allocation of funds under this chapter, each revision to the floodplain management activities must be approved by the department of ecology, in consultation with the department of fish and wildlife.
No participation with a county or other municipal corporation for flood control maintenance projects may occur unless the county engineer of the county within which the flood control maintenance project is located certifies that a comprehensive flood control management plan has been completed and adopted by the appropriate local authority, or is being prepared for all portions of the river basin or other area, within which the project is located in that county, that are subject to flooding with a frequency of one hundred years or less.
