(A) Development may not occur in the floodplain where alternative locations exist due to the inherent hazards and risks involved. Before a permit is issued, the applicant shall demonstrate that new structures cannot be located out of the floodplain and that encroachments onto the floodplain are minimized.
(B) In all areas of special flood hazard, the following provisions are required:
(1) All new construction and substantial improvements shall be:
(a) Anchored to prevent flotation, collapse or lateral movement of the structure;
(b) Constructed with flood-resistant materials and utility equipment resistant to flood damage; and
(c) Constructed by methods and practices that minimize flood damage.
(2) Electrical, ventilation, plumbing, heating and air conditioning equipment (including ductwork) and other service facilities shall be designed and located so as to prevent water from entering or accumulating within the components during conditions of flooding. This requirement does not preclude the installation of outdoor faucets for shower heads, sinks, hoses and the like, as long as cutoff devices and backflow devices are installed to prevent contamination to the service components and thereby minimizing any flood damage to the building;
(3) All new and replacement water supply systems shall be designed to minimize or eliminate the infiltration of flood waters into the system;
(4) New and replacement sanitary sewerage systems shall be designed to minimize or eliminate the infiltration of flood waters into the systems and discharges from the systems into the flood waters;
(5) On-site waste disposal systems shall be located and constructed to avoid impairment to them or contamination from them during flooding;
(6) Any alteration, repair, reconstruction or improvement to a structure which is in compliance with the provisions of this chapter shall meet the requirements of new construction as contained in this chapter. This includes post-FIRM development and structures;
(7) Non-conforming buildings or uses may not be enlarged, replaced or rebuilt unless such enlargement or reconstruction is accomplished in conformance with the provisions of this chapter; provided, however, nothing in this article shall prevent the repair, reconstruction or replacement of an existing building or structure located totally or partially within the floodway; provided that, the bulk of the building or structure below base flood elevation in the floodway is not increased; and, provided that, such repair, reconstruction or replacement meets all of other requirements of this chapter; and
(8) A building must meet the specific standards for floodplain construction outlined in § 20-63 of this chapter, as well as any applicable Americans with Disabilities Act (ADA), being 42 U.S.C. §§ 1201 et seq. requirements. The ADA is not justification for issuing a variance or otherwise waiving these requirements. Also, the cost of improvements required to meet the ADA provisions shall be included in the costs of the improvements for calculating substantial improvement.
