A.   Statutory Authority: The legislature of the state of Idaho by Idaho Code sections 46-1020 through 46-1024, authorized local government units to adopt a floodplain map and floodplain management ordinance that identifies floodplains and that sets forth minimum development requirements in floodplains that are designed to promote the public health, safety, and general welfare of its citizenry.
   B.   Statement Of Purpose: It is the purpose of this chapter 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.   Require that development that is vulnerable to floods, including structures and facilities necessary for the general health, safety and welfare of citizens, be protected against flood damage at the time of initial construction;
      2.   Restrict or prohibit uses which are dangerous to health, safety and property due to water or erosion hazards, or which increase flood heights, velocities, or erosion;
      3.   Control filling, grading, dredging and other development within the area of special flood hazard which may increase flood damage or erosion;
      4.   Prevent or regulate the construction of flood barriers that will unnaturally divert floodwaters or that may increase flood hazards to other lands;
      5.   Control the alteration of natural floodplains, stream channels, and natural protective barriers that help to store or channel floodwaters.
   C.   Objectives: The objectives of this chapter are to:
      1.   Protect human life, health and property;
      2.   Minimize damage to public facilities and utilities such as water purification and sewage treatment plants, water and gas mains, electric, telephone and sewer lines, streets and bridges located in floodplains;
      3.   Help maintain a stable tax base by providing for the sound use and development of flood prone areas;
      4.   Minimize expenditure of public money for costly flood control projects;
      5.   Minimize the need for rescue and emergency services associated with flooding and generally undertaken at the expense of the general public;
      6.   Minimize prolonged business interruptions.
   D.   Severability: If any provision of this chapter or its application to any person or circumstance is held invalid by a court of competent jurisdiction, the invalidity does not affect other provisions or applications of this chapter that can be given effect without the invalid provision or application, and to that end the provisions of this chapter are severable.
   E.   Repeal Of Conflicting Provisions: Upon enactment of this chapter all other ordinances or parts of ordinances in conflict herewith, are hereby repealed. All sections of the aforementioned ordinances repealed by this chapter shall remain in force as to the authorization and enforcement of said ordinances prior to the effective date hereof.
   F.   Warning And Disclaimer Of Liability: The degree of flood protection required by this chapter is considered reasonable for regulatory purposes and is based on scientific and engineering considerations. Larger floods can and will occur. Flood heights may be increased by manmade or natural causes. This chapter does not imply that land outside the special flood hazard areas or uses permitted within such areas will be free from flooding or flood damages. This chapter shall not create liability on the part of the city of Blackfoot or by any officer or employee thereof for flood damages that result from reliance on this chapter or an administrative decision lawfully made hereunder.
