§ 38-72. General standards.

(a)

In all areas of special flood hazard, the following are required for all new construction and substantial improvements:

(1)

All new construction or substantial improvements shall 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;

(2)

All new construction or substantial improvements shall be constructed by methods and practices that minimize flood damage;

(3)

All new construction or substantial improvements shall be constructed with materials resistant to flood damage;

(4)

All new construction or substantial improvements shall be constructed with electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities that are designed and located to prevent water from entering or accumulating within the components during conditions of flooding;

(5)

All new and replacement water supply systems shall be designed to minimize or eliminate infiltration of floodwaters into the system;

(6)

New and replacement sanitary sewer systems shall be designed to minimize or eliminate infiltration of floodwaters into the system and discharge from the systems into floodwaters; and

(7)

Onsite waste disposal systems shall be located to avoid impairment to or contamination from them during flooding.

(b)

For the purposes of this article, all mixed-use structures are subject to the more stringent requirements of residential structures.

(c)

A substantial improvement or substantial damage to an existing structure triggers a requirement to bring the entire structure into full compliance with the provisions of this article. The existing structure, as well as any reconstruction, rehabilitation, addition, or other improvement, must meet the standards of new construction in this article.

(d)

Any improvement to an existing structure that is less than a substantial improvement requires the improvement, but not the existing structure, to be in full compliance with the provisions of this article.

(e)

Construction of basement foundations in any special flood hazard area is prohibited.

(f)

The placement of a manufactured home in the floodway is prohibited.
