Moderate-to low-risk areas are identified on the Flood Insurance Rate Maps (FIRMs) as:
Shaded Zone X- These properties are in moderate to the low-risk area. The risk is reduced in these areas but not eliminated.
Zone X- These properties are in an area of overall lower risk. High-risk areas are identified on the FIRMs as:
Zones AE, A, AH, AR, A99, or AO - These properties have at least a 26 percent chance of flooding over the life of a 30-year mortgage.
Zones VE or V - These properties also have at least a 26 percent chance of flooding over the life of a 30-year mortgage. In addition, these properties face hazards associated with coastal storm waves and storm surge.

A FIRM will generally show a community's base flood elevations, flood zones, and floodplain boundaries. As a property owner/renter, you can use this map to get a reliable indication of what flood zone you're in. The City of Corpus Christi joined the NFIP in 1970 and has undergone several FIRM revisions since. The latest community-wide FIRM revision was in 1992.
FEMA is currently completing the Nueces County Coastal Study, which is the most comprehensive study to date. As a result of this study, FIRMs will be revised to adjust the Base Flood Elevations (BFEs) and Special Flood Hazard Areas (SFHAs) within Nueces County.
