13-2-I CONSTRUCTION SUBJECT TO GEOLOGIC, FLOOD, OR OTHER NATURAL HAZARD: STATUTORY AUTHORIZATION, FINDINGS OF FACT, PURPOSE AND METHODS

SECTION A. STATUTORY AUTHORIZATION SECTION B. FINDINGS OF FACT 1. The flood hazard areas of Erda are subject to periodic inundation which results in loss of life and property, health and safety hazards, disruption of commerce and governmental services, and extraordinary public expenditures for flood protection and relief, all of which adversely affect the public health, safety, and general welfare. 2. These flood losses are created by the cumulative effect of obstructions in floodplains which cause an increase in flood heights and velocities, and by the occupancy of flood hazard areas by uses vulnerable to floods and hazardous to other lands because they are inadequately elevated, flood-proofed, or otherwise protected from flood damage. SECTION C. STATEMENT OF PURPOSE It is the purpose of this ordinance to promote the public health, safety, and general welfare and to minimize public and private losses due to flood conditions in specific areas by provisions designed to: 1. Protect human life and health; 2. Minimize expenditure of public money for costly flood control projects; 3. Minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public; 4. Minimize prolonged business interruptions; 5. Minimize damage to public facilities and utilities such as water and gas mains, electric, telephone and sewer lines, streets, and bridges located in floodplains; 6. 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; and 7. Insure that potential buyers are notified that property is in a flood area. SECTION D. METHODS OF REDUCING FLOOD LOSSES In order to accomplish its purposes, this ordinance uses the following methods: 1. Restrict or prohibit uses that are dangerous to health, safety, or property in times of flood, or cause excessive increases in flood heights or velocities; 2. Require that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction; 3. Control the alteration of natural floodplains, stream channels, and natural protective barriers, which are involved in the accommodation of flood waters; 4. Control filling, grading, dredging, and other development which may increase flood damage; and 5. Prevent or regulate the construction of flood barriers which will unnaturally divert flood waters, or which may increase flood hazards to other lands.
