§ 109-16. U-1 Unclassified District.

The intent of the U-1 district is to guide development in the identified floodplain and floodway areas so as to lessen the potential for damage and destruction to both private and public property, to lessen public expenditures for flood relief and flood control projects, and to promote and protect the public health and safety.

One-family dwellings.

(3)

Special provisions. No structure (temporary or permanent, principal or accessory), fill, deposit, obstruction, storage of materials or equipment, channel alterations, or other uses shall be permitted which, acting alone or in combination with existing or proposed uses adversely affects the efficiency of the floodway or unduly increases flood heights. For any such use which may cause or affect the above, as determined by either the administrator, the commission or the council, a review shall be conducted by the state department of natural resources to determine if the efficiency and capacity of the floodway is adversely affected or unduly restricted of if flood heights are unduly increased.

(4)

Standard and requirements.

a.

The state department of natural resources shall establish floor elevations, encroachment limits, floodproofing methods, and other such controls as may be necessary in order to ensure compliance with the above provisions. The council will ensure that such controls, where necessary, will be established and followed.

b.

The administrator, the commission, or the council may require the proponent for development to submit a statement from the county soil and water conservation district as to the composition of the soils in the vicinity of the site, and from the county department of health as to the capability of the land to handle the proposed septic waste system.

(5)

Height regulations. Any building hereafter erected or structurally altered may be erected to any height not in conflict with other existing or future resolutions of the council.
