It is the purpose of this chapter to protect and preserve the rights, privileges and property of the City and its residents and to preserve and improve the peace, safety, health, welfare and comfort and convenience of its residents by minimizing flood losses with provisions designed to:
1. Reserve sufficient flood plain area for the conveyance of flood flows so that flood heights and velocities will not be increased substantially.
2. Restrict or prohibit uses which are dangerous to health, safety, or property in times of flood or which cause excessive increases in flood heights or velocities.
3. Require that uses vulnerable to floods, including public utilities which serve such uses, be protected against flood damage at the time of initial construction or substantial improvement.
4. Protect individuals from buying lands which may not be suited for intended purposes because of flood hazard.
5. Assure that eligibility is maintained for property owners in the community to purchase flood insurance through the National Flood Insurance Program.
