Flood Zone Information

Disclaimer and Appropriate Use 

The flood maps in the LIST-IT MLS System are based on the Q3 Digital Dataset from FEMA.  The colorization of the maps and the Flood Zone indication implied by the placement of real estate on the maps should not be interpreted as a Flood Certification or a replacement for a survey on the property. The maps should be used as a preliminary indication that flood exposure could be an issue which a purchaser of the real estate should weigh when making their decision.  For more information about this data click this link.

Flood Zone Definitions

Zone V: SFHAs along coasts subject to inundation by the 100-year flood with the additional hazards associated with storm waves. (Zone VE is used on new and some revised maps in place of Zones V1-30.)

Zone A: SFHAs subject to inundation by the 100-year flood. Because detailed hydraulic analyses have not been performed, no base flood elevations or depths are shown. Mandatory flood insurance purchase requirements apply.

Zones AE and A1-30: SFHAs subject to inundation by the 100-year flood determined in a Flood Insurance Study by detailed methods. Base flood elevations are shown within these zones. Mandatory flood insurance purchase requirements apply. (Zone AE is used on new and some revised maps in place of Zone A1-30.)

Zone AH: SFHAs subject to inundation by the 100-year shallow flooding (usually areas of ponding) where average depths are between one and three feet. Base flood elevations derived from detailed hydraulic analyses are shown in this zone. Mandatory flood insurance purchase requirements apply.

Zone AO: SFHAs subject to inundation by types of 100-year 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 requirements apply.

Zone A99: SFHAs subject to inundation by the 100-year flood which will be protected by a federal flood protection system when construction has reached specified statutory progress toward completion. No base flood elevations or depths are shown . Mandatory flood insurance purchase requirements apply.

Zones B,C, and X: These areas have been identified in the community flood insurance study as areas of moderate or minimal hazard from the principal source of flood in the area. However, buildings in these zones could be flooded by severe, concentrated rainfall coupled with inadequate local drainage systems. Local storm water drainage systems are not normally considered in the community's Flood Insurance Study. The failure of a local drainage system creates areas of high flood risk within these rate zones. Flood insurance is available in participating communities but is not required by regulation in these zones. (Zone X is used on new and some revised maps in place of Zones B and C.)

Zone D: Unstudied areas where flood hazards are undetermined but flooding is possible. No mandatory flood insurance purchase requirements apply, but coverage is available in participating communities.
