1. Review all permit applications to determine that the special flood hazard area development permit requirements of this chapter have been satisfied.

2. Review all special flood hazard area development permit applications to determine that all necessary permits have been obtained from those governmental agencies from which approval is required by federal or state law, including Section 404 of the Federal Water Pollution Control Act Amendments of 1972, 33 U.S.C. 1334.

3. Review all special flood hazard area development permits to determine if the proposed development is located in the floodway. If located in the floodway, assure that the encroachment provisions of MMC 14.01.150 are met.

4. Review all permit applications to determine whether proposed building sites will be reasonably safe from flooding. If a proposed building site is in an area of special flood hazard, all new construction and substantial improvements shall (a) be designed (or modified) and adequately anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy, (b) be constructed with materials resistant to flood damage, (c) be constructed by methods and practices that minimize flood damage, and (d) be constructed with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.

5. Review subdivision proposals and other new development, including manufactured home parks or subdivisions, to determine whether such proposals will be reasonably safe from flooding. If a subdivision proposal or other proposed new development is in an area of special flood hazard, any such proposals shall be reviewed to assure that (a) all such proposals are consistent with the need to minimize flood damage within the area of special flood hazard, (b) all public utilities and facilities, such as sewer, gas, electrical, and water systems, are located and constructed to minimize or eliminate flood damage, and (c) adequate drainage is provided to reduce exposure to flood hazards.

6. Notify FEMA when annexations occur in the special flood hazard area.

1. Where base flood elevation data is provided through the flood insurance study or required as in subsection (B) of this section, obtain and record the actual elevation (in relation to mean sea level) of the lowest floor (including basement) of all new or substantially improved structures, and whether or not the structure contains a basement.

2. For all new or substantially improved floodproofed structures:

3. Certification required by the encroachment provisions found at MMC 14.01.150.

4. Records of all variance actions, including justification for their issuance.

5. Improvement and damage calculations.

6. Maintain for public inspection all records pertaining to the provisions of this chapter.

1. The floodplain manager shall notify adjacent communities and the Department of Ecology prior to any alteration or relocation of a watercourse, and submit evidence of such notification to the Federal Insurance Administration.

2. Assure that the flood carrying capacity within the altered or relocated portion of any watercourse is maintained.

1. If a project will alter the BFE or boundaries of the SFHA, then the project proponent shall provide the community with engineering documentation and analysis regarding the proposed change. If the change to the BFE or boundaries of the SFHA would normally require a letter of map change, then the project proponent shall initiate, and receive approval of, a conditional letter of map revision (CLOMR) prior to approval of the development permit. The project shall be constructed in a manner consistent with the approved CLOMR.

2. If a CLOMR application is made, then the project proponent shall also supply the full CLOMR documentation package to the floodplain administrator to be attached to the floodplain development permit, including all required property owner notifications.
