The elevation of the lowest floor, excluding the basement or crawlway,
shall be at or above the flood protection elevation on fill. The fill

The basement or crawlway floor may be placed at the regional flood
elevation if it is floodproofed to the flood protection elevation.
No basement or crawlway floor is allowed below the regional flood
elevation;

(4)
In developments where existing street or sewer line elevations make compliance with Subsection B(3) impractical, the Village of Kimberly may permit new development and substantial improvements where access roads are at or below the regional flood elevation, if:
(a)
The Village of Kimberly has written assurance from police, fire

bridges shall be designed to be compatible with comprehensive floodplain
development plans:
(1)
When failure of public utilities, streets and bridges would endanger public health or safety, or where such facilities are deemed essential, construction of and substantial improvements to such facilities may only be permitted if they are floodproofed in compliance with § 495-28 to the flood protection elevation; and
(2)
Minor roads or nonessential utilities may be constructed at lower

flood elevation.
