The Zoning Administrator shall review all permit applications to determine whether proposed building sites will be reasonably safe from flooding and assure that all necessary permits have been received from those governmental agencies whose approval is required by federal or state law.
If a proposed building site is in a flood-prone area, all new construction and substantial improvements shall:
A. 
Be designed and 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 flood-resistant materials;
C. 
Be constructed by methods and practices that minimize flood damages; and
D. 
Have all mechanical and utility equipment elevated to or above the flood protection elevation.
If a subdivision or other proposed new development is in a flood-prone area:
A. 
Such proposed subdivision or other proposed new development shall be consistent with the need to minimize flood damage within the flood-prone area;
B. 
Public utilities and facilities such as sewer, gas, electrical, and water systems shall be located and constructed to minimize or eliminate flood damage; and
C. 
Adequate drainage shall be provided to reduce exposure to flood hazards.
All subdivision proposals (including manufactured home parks) shall include regional flood elevation and floodway data for any development that meets the "subdivision" definition of this chapter and all other requirements in § 226-7-3.
No floodplain development shall:
A. 
Obstruct flow, defined as development which blocks the conveyance of floodwaters by itself or with other development, causing any increase in the regional flood height; or
B. 
Cause any increase in the regional flood height due to floodplain storage area lost.
The Zoning Administrator shall deny permits if it is determined the proposed development will obstruct flow or cause any increase in the regional flood height, based on the officially adopted FIRM or other adopted map, unless the provisions of § 226-7-10 are met.
A. 
No land use permit to alter or relocate a watercourse in a mapped floodplain shall be issued until the Zoning Administrator has notified in writing all adjacent municipalities and the DNR and FEMA regional offices, and the applicant has secured all necessary state and federal permits. The standards of §§ 226-2-5 and 226-2-6 must be met and the flood-carrying capacity of any altered or relocated watercourse shall be maintained.
B. 
As soon as is practicable, but not later than six months after the date of the watercourse alteration or relocation and pursuant to § 226-7-10, the Village shall apply for a LOMR from FEMA. Any such alterations must be reviewed and approved by FEMA and the DNR through the letter of map change ("LOMC") process.
