A. The Director shall notify adjacent jurisdictions and the state Department of Ecology or successor agency prior to any alteration or relocation of a water course, and submit evidence of such notification to FEMA.

B. Require that maintenance be provided within the altered or relocated portion of said water course so that the flood carrying capacity is not diminished. If the maintenance program does not call for cutting of native vegetation, the system shall be oversized at the time of construction to compensate for said vegetation growth or any other natural factor that may need future maintenance.

C. An applicant for a project that will alter or relocate a water course shall submit a request for a conditional letter of map revision (CLOMR) where required by FEMA. The City shall not grant any permit unless FEMA issues the CLOMR and the provisions of the letter are made a part of the permit requirements. [Ord. 726 § 2 (Exh. B), 2019.]
