A. Land which contains areas within a regulatory floodplain or erosion hazard area shall not be platted for residential occupancy or building sites unless each lot contains a building site, either natural or manmade, which is not subject to flooding or erosion by the base flood.
B. Lots shall be configured so that encroachment into the regulatory floodplain and erosion hazard area is minimized. It is preferred that building sites and other development be located outside of the regulatory floodplain and erosion hazard area.
C. In regulatory floodplain areas where fill is to be used to raise the elevation of the building site, the building shall be located not less than ten feet landward from any edge of the fill, and protected from erosion in accordance with Section 16.26.040, unless a study/analysis prepared and sealed by an Arizona registered civil engineer demonstrates a lesser distance or the absence of erosion protection is acceptable. No fill shall be placed in any regulatory floodplain or floodway, nor shall any fill be placed where it diverts, retards or obstructs the flow of water to such an extent that it creates a danger or hazard to life or property.
D. Any dwelling unit built within a regulatory floodplain shall be constructed so as to place the elevation of the lowest floor of the dwelling unit at or above the regulatory flood elevation.
E. All building sites shall be graded and compacted to comply with FEMA regulations for fill and to comply with foundation elevation requirements under the international uniform building code, and shall be graded and compacted so that the top of any exterior foundation shall extend above the elevation of the street gutter at the point of discharge, or above the inlet of an approved drainage device, a minimum of twelve inches plus two percent for a minimum of twenty-five feet away from the foundation, but in no case should the finished floor elevation of habitable structures be below the regulatory flood elevation.
