On the FIRM covering Dorchester County, zones that start with A or V are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). Zone AE near Eldorado means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Land near Eldorado in shaded X (Zone B on older maps) falls between the base flood and the 500-year flood. Unshaded Zone X near Eldorado is minimal risk.

What a flood zone means for a Dorchester County buyer
Insurance is the practical stake for a Dorchester County buyer. Where a building in East New Market falls inside an A or V zone and secures a loan from a federally regulated or insured lender, flood insurance is mandatory, provided the community near East New Market takes part in the National Flood Insurance Program. Outside the A zones around Eldorado, coverage is optional; pricing a policy for land near Eldorado is still worth a call. Where a structure near East New Market looks higher than the shading suggests, the titleholder can ask FEMA for a Letter of Map Amendment (LOMA), generally backed by an elevation certificate from a surveyor who works in the county. Placing fill on low ground near East New Market frequently requires a permit and an elevation check; the county floodplain administrator can say what applies.
