DISCLAIMER:

By clicking 'I AGREE', you understand the following information:

This application uses FEMA’s National Flood Hazard Layer (NFHL), a digital database that contains the flood hazard map information from FEMA’s National Flood Insurance Map.

The information contained was generated from GIS data maintained by different sources and agencies. Areas depicted by these digital products are approximate, and are not necessarily accurate to mapping, surveying or engineering standards. No portion of the information should be considered or used as a legal document. These digital products are for illustration purposes only, are not suitable for site-specific decision making, are subject to constant change, and may not be complete, accurate or current. Any specific coordinates may be in error by several hundred feet or more. A digital layer may have registration errors and not overlay with other data layers correctly.

Coconino County provides this information with the understanding that it is not guaranteed to be accurate, correct or complete. Conclusions drawn from this information are the responsibility of the user. Every effort has been made to ensure the accuracy, correctness and timeliness of the materials presented. However, the County assumes no liability for damages incurred directly or indirectly as a result of incomplete, incorrect or omitted information. The user of this information assumes all liability for their dependence on this information and assumes responsibility for the information.

Floodplain Definitions

Please see FEMA's website for complete definitions of flood zones and required insurance.

Floodway:

A "Regulatory Floodway" means the channel of a river or other watercourse and the adjacent land areas that must be reserved in order to discharge the base flood without cumulatively increasing the water surface elevation more than a designated height. Communities must regulate development in these floodways to ensure that there are no increases in upstream flood elevations. For streams and other watercourses where FEMA has provided Base Flood Elevations (BFEs), but no floodway has been designated, the community must review floodplain development on a case-by-case basis to ensure that increases in water surface elevations do not occur, or identify the need to adopt a floodway if adequate information is available.

Zone A:

Areas subject to inundation by the 1-percent-annual-chance flood event generally determined using approximate methodologies. Because detailed hydraulic analyses have not been performed, no Base Flood Elevations (BFEs) or flood depths are shown. Mandatory flood insurance purchase requirements and floodplain management standards apply.

Zone AE:

Areas subject to inundation by the 1-percent-annual-chance flood event determined by detailed methods. Base Flood Elevations (BFEs) are shown. Mandatory flood insurance purchase requirements and floodplain management standards apply.

Zone AH:

Areas subject to inundation by 1-percent-annual-chance shallow flooding (usually areas of ponding) where average depths are between one and three feet. Base Flood Elevations (BFEs) derived from detailed hydraulic analyses are shown in this zone. Mandatory flood insurance purchase requirements and floodplain 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. Average flood depths derived from detailed hydraulic analyses are shown in this zone. Mandatory flood insurance purchase requirements and floodplain management standards apply.
Some Zone AO have been designated in areas with high flood velocities such as alluvial fans and washes. Communities are encouraged to adopt more restrictive requirements for these areas.

Zone D:

The Zone D designation is used for areas where there are possible but undetermined flood hazards, as no analysis of flood hazards has been conducted. The designation of Zone D is also used when a community incorporates portions of another community’s area where no map has been prepared.

0.2 PCT ANNUAL CHANCE FLOOD HAZARD

Moderate flood hazard areas, labeled Zone B or Zone X (shaded) are also shown on the FIRM, and are the areas between the limits of the base flood and the 0.2-percent-annual-chance (or 500-year) flood.

Zone X

The areas of minimal flood hazard, which are the areas outside the Special Flood Hazard Area (SFHA) and higher than the elevation of the 0.2-percent-annual-chance flood, are labeled Zone C or Zone X (unshaded).
