This section is included in your selections.

A. The platting board shall deny permission to subdivide land within flood hazard areas unless the following requirements have been fulfilled:

1. Require that all new subdivision proposals and other proposed development (including proposals for manufactured home parks and subdivision) greater than 50 lots or five acres, whichever is the lesser, include within such proposals base flood elevation data.

2. Obtain, review and reasonably utilize any base flood elevation from a federal, state or other source, as criteria for requiring that new construction, substantial improvements or other development in zone A on the FHBM.

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

4. Notify, in riverine situations, adjacent communities and the State Coordinating Office prior to any alterations or relocated portions of any watercourse is maintained.

5. The land subdivision and associated development are consistent with the need to minimize flood damages.

6. All public utilities and facilities such as sewer, gas, electrical and water systems shall be located, elevated or constructed to minimize or eliminate flood damage.

7. Adequate drainage shall be provided to reduce the exposure of structures, utilities and facilities to flood hazards.

8. Evidence has been submitted that all necessary permits required by state or federal law have been applied for and granted. At a minimum, this includes the Alaska Department of Fish and Game, the Alaska Department of Natural Resources and the U.S. Army Corps of Engineers, Alaska District.

9. The preliminary and final plat shall include the ground elevation and the regulatory flood elevation, if available, at convenient reference points.

10. The flood hazard area, if identified, shall be labeled “flood hazard area” on preliminary and final plats. The fact that a lot is in the flood hazard area shall be disclosed in any contract to purchase, rent or lease the lot.

B. All new or replacement water supply systems and sanitary sewage systems, including on-site systems, shall be designed to minimize or eliminate infiltration of flood waters into the systems and discharges from the systems into flood waters.

C. All new or replacement public utilities such as gas, electric and telephone systems shall be designed or constructed to eliminate disruptions due to flooding and associated hazards.

D. In determining if the requirements of this section are fulfilled, the platting board shall consider the intent of this chapter and at least:

1. The danger of life and property due to the increased flood heights or velocities caused by subdivision fill, roads, structures and intended uses.

2. The danger that structures may be swept onto other lands or downstream to the injury of others.

3. The adequacy of proposed water supply and sanitation systems and the ability of these systems to prevent disease, contamination and unsanitary conditions under flood conditions.

4. The susceptibility of the proposed facility and its contents to flood damage and the effect of such damage on the individual owner.

5. The requirements of the subdivision for a waterfront location.

6. The availability of alternative locations not subject to flooding for the proposed subdivision and land uses.

7. The compatibility of the proposed uses with existing development and development anticipated in the foreseeable future.

8. The relationship of the proposed subdivision to the flood plain management program for the area.

9. The safety of access to the property for emergency vehicles in times of flood.

10. The expected heights, velocity, duration, rate of rise and sediment transport of the flood waters expected at the site.

11. The costs of providing governmental services during and after flood conditions, including maintenance and repair of public utilities and facilities such as sewer, gas, electrical and water systems and streets and bridges.

12. The installation of valves or controls on sanitary and storm drains which permit the drains to be closed to prevent backup of sewage and storm waters into buildings or structures. (Ord. 04-08-075)
