Statutory Authorization The Legislature of the State of Florida has In Chapter 125, Florida Statutes, delegated the responsibility to local governmental units to adopt regulations designed to promote the public health, safety, and general welfare of its citizenry. SECTION 2. Findincjs of Fact (I) The flood hazard areas of CoIller County are subject to periodic Inundation whlch could result in loss of life, pro- 1 party damage, health, and safety hazards, disruption of com- merce and governmental services, extraordinary public expen- ditures for flood protection and roller, and Impairment of the tax base, all of which could adversely affect the public health, safety and general welfare. (2) These flood losses are caused by the cumulative effect of obstructions In flood plains causing Increases In flood heights and velocities, and by the occupancy in flood hazard areas by structures vulnerable to floods or hazardous to other lands whlch are inadequately elevated, floodproofed, or otherwise inadequately protected from flood damages. SECTION 3. Statement of Purpose It is the purpose o1' this ordinance to promote [h~ public health, safety and general welfare and to mlnlmlze public and private losses due to flood conditions In specific areas by provisions designed: (I) To protect human llfe and health. (2i To minimize expenditure of public money for costly and envi- ronmentally unsound flood control projects. (3) To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at tho expense of the general public; (4)To minimize prolonged business Interruptions; (5) To mlnlmlze damage to public facllltles and utilities such as water and gas malns, electric, telephone and sewer lines, streets and bridges located In areas of speclal flood hazard; (6) To help maintain a stable tax base by providing for the sound use and development of flood-prone areas In such a manner as to minimize future flood blight areas; (7) To insure to the greatest degree possible that potential home buyers are notified that property is in an area of special flood hazard; and~ (8) To Insure that those, who occupy the areas of' special flood hazard assume responsibilites for their actions. SECTION 4: Methods of Reduclnc~ Flood Losses / In orc~er to accomplish its purposes~ thls ordinance includes meth- ods and provisions for: (1) Restricting or prohibiting uses whlch are dangerous to health, safety, and property due to wateP or erosion hazards, or which result In damaging ~ncreases in erosion or In flood heights or velocities; (2) Requiring that uses vulnerable to flood$~ Including facilities which serve such uses, be p~-otectad against flood damage at the time of initial construction; (3) Controlling the alteration of natural flood plains; stream channels, and natural protectlve barriers, which help accom- modate or channel flood waters; (4) Controlling fllllng, gradlng, dredging, and other development which may increase flood damage; and~ (5) Preventing or regulating the constructlon of flood barriers which will unnaturally divert flood waters or which may increase flood hazards in other areas.
