A. Statement of Purpose. It is the purpose of this chapter to promote the public health, safety, and general welfare, reduce the cost of flood insurance, and minimize public and private losses due to flood conditions in specific areas by provisions designed:

1. To protect human life and health;

2. To minimize expenditure of public money and costly flood control projects;

3. To minimize the need for rescue and relief efforts associated with flooding and generally undertaken at the expense of the general public;

4. To minimize prolonged business interruptions;

5. To minimize damage to public facilities and utilities such as water and gas main, electric, telephone and sewer lines, streets, and bridges located in areas of special flood hazard;

6. To help maintain a stable tax base by providing for the sound use and development of areas of special flood hazard to minimize future flood blight areas;

7. To help ensure that potential buyers are notified that property is in an area of special flood hazard; and

8. To help ensure that those who occupy areas of special flood hazard assume responsibility for their actions.

B. Methods of Reducing Flood Losses. In order to accomplish its purposes and to be consistent with the criteria set forth in Section 60 of the National Flood Insurance Program Regulations (NFIPR), this chapter includes methods and provisions for:

1. Restricting or prohibiting uses which are dangerous to health, safety, and property due to water or erosion hazards or which result in damaging increases in erosion or in flood heights or velocities;

2. Requiring that uses vulnerable to floods, including facilities which serve such uses, be protected against flood damage at the time of initial construction;

3. Controlling the alteration of natural flood plains, stream channels, and protective barriers that help accommodate or channel floodwaters;

4. Controlling filling, grading, dredging, and other development that may increase flood damage; and

5. Preventing or regulating the construction of flood barriers that unnaturally divert floodwaters or may increase flood hazards in other areas.
