. . . 002257 preparedness plans, flood control works, and flood plain management regulations. Flood plain management regulations mean zoning ordinances, subdivision regulations, building codes, health regulations, special purpose ordinances (such as a flood plain ordinance, grading ordinance or erosion control ordinance), and other applications of police power. They provide standards for the purpose of flood damage prevention and reduction. There are no existing tribal flood plain management regulations to guide development with respect to flood damage prevention and reduction for the five Indian reservations bordering the Floodway. In addition, none of the five tribes presently participate in the National Flood Insurance Program. Adequate mapping of flood-prone areas does not exist for all the entire lands within the reservations. The National Flood Insurance Act of 1968, which created the National Flood Insurance Program, was enacted to provide previously unavailable flood insurance protection to property owners in flood-prone areas. For the state, county, city, or other political subdivision of a state, or any Indian Tribe to become fully eligible under the National Flood Insurance Program, it must have authority to adopt and enforce flood plain management regulations for areas within its jurisdiction and flood hazard mapping must have been completed for all jurisdictional lands. Furthermore, such entities must adopt and enforce flood plain management regulations that meet the federal flood plain management criteria of the program. These regulations must be legally enforceable and applied uniformly throughout the area of jurisdiction to all privately and publicly owned land within flood-prone and flood-related erosion-prone areas. They are to take precedence over less restrictive conflicting local laws, ordinances, or codes. The States of Arizona, California, and Nevada have developed model flood plain management regulations which meet the minimum requirements of the respective State statutes and the National Flood Insurance Act of 1968, as amended. These, together with handbooks and other guidance material, are intended to assist local entities in the development of their flood plain management regulations. RECOMMENDATION: It is recommended that the five Indian tribes, consistent with Section 15 of the Colorado River Floodway Protection Act, adopt flood plain management regulations. It is recommended further that (l) any adopted regulations meet "\TIII-4
