1% annual chance flood zone without base flood elevations
Zone A is a high-risk flood zone where FEMA has determined there is a 1% annual chance of flooding, but has not conducted detailed hydraulic analysis to determine Base Flood Elevations.
Zone A areas are typically in less-developed regions where detailed flood studies have not been performed. The risk is the same as Zone AE, but without the precision of established flood depths.
Without a BFE, building requirements may be more conservative, and insurance rating may use different methods.
Flood insurance is required. This is a Special Flood Hazard Area (SFHA).
No — Base Flood Elevations have not been determined for Zone A. An Elevation Certificate can help establish your property's flood risk more precisely.
