    Zone AE: Areas with a 1% annual chance of flooding and a 26% chance of flooding over the life of a 30-year mortgage. Flood event determined by detailed methods. Mandatory flood insurance purchase requirements and flood-plain management standards apply.

    Zone A: Areas with a 1% annual chance of flooding and a 26% chance of flooding over the life of a 30-year mortgage. Flood event generally determined using approximate methodologies. Mandatory flood insurance purchase requirements and flood-plain management standards apply.

    Zone AO: Areas subject to inundation by 1-percent-annual-chance shallow flooding (usually sheet flow on sloping terrain) where average depths are between one and three feet. Some Zone AO have been designated in areas with high flood velocities such as alluvial fans and washes.

    Flooding is the overflow of water onto lands that are normally dry, and is the most prevalent and destructive (on an annual basis) geologic hazard affecting the St. George – Hurricane metropolitan area. Damage from flooding includes inundation of land and property, erosion, deposition of sediment and debris, and the force of the water itself, which can damage property. The high flood hazard in the study area results from the complex interaction of the area’s rugged topography and seasonal weather patterns that del
