(a) The purpose of these provisions is to prevent the loss of property and life, the creation of health and safety hazards, the disruption of commerce and governmental services, the extraordinary and unnecessary expenditure of public funds for flood protection and relief, and the impairment of the tax base by:
(1) Regulating uses, activities, and development that, acting alone or in combination with other existing or future uses, activities, and development, will cause unacceptable increases in flood heights, velocities and frequencies.
(2) Restricting or prohibiting certain uses, activity and development from locating within areas subject to flooding.
(3) Requiring all those uses, activities and developments that do occur in flood- prone areas to be protected and/or floodproofed against flooding and flood damage.
(4) Protecting individuals from buying lands and structures which are unsuited for intended purposes because of flood hazards.
(b) These provisions shall apply to all lands within the jurisdiction of the City and shown as being located within the boundaries of the designated flood plain districts as defined on the National Flood Insurance Program (NFIP) maps and which are considered as a part of the official Zoning Map.
(c) No structure or land shall hereafter be used and no structure shall be located, relocated, constructed, reconstructed, enlarged or structurally altered except in full compliance with the terms and provisions of this article and any other applicable ordinances and regulations which apply to uses within the jurisdiction of this article.
(d) The degree of flood protection sought by the provisions of this article is considered reasonable for regulatory purposes and is based on acceptable engineering methods of study. Larger floods may occur on rare occasions. Flood heights may be increased by man-made or natural causes, such as ice jams and bridge openings restricted by debris. This article does not imply that areas outside the flood plain districts or that land uses permitted within such districts will be free from flooding or flood damages.
(e) This article shall not create liability on the part of the City or any officer or employee thereof for any flood damages that result from reliance on this article or any administrative decision lawfully made thereunder.
