Reading the zones on a Lawrence County flood map
On the FIRM covering Lawrence County, zones that start with A or V are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. Where a Lawrence County tract displays Zone AE, there's a base flood elevation to compare a building against; in Zone A there isn't one. Shaded Zone X around Ethridge is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded Zone X near Lawrenceburg is minimal risk.
Low ground and small streams around Ethridge
A creek near Lawrenceburg that displays no detailed zone can still flood; FEMA says moderate- and low-risk areas still carry risk.
Flood insurance and building rules in Lawrence County
The zone displays up again when a loan on a house near Lawrenceburg is underwritten. When a structure near Lawrenceburg is mapped in a high-risk zone and carries a federally backed mortgage, a flood policy becomes a loan condition; that applies where the local government around Lawrenceburg is in the National Flood Insurance Program. For a Lawrence County home in shaded or unshaded X, coverage is optional, although some lenders require it anyway. If a building near Lawrenceburg sits above the flood line, a Letter of Map Amendment request is the formal route, supported by elevation data from a licensed surveyor. Adding on to a house near Lawrenceburg inside the zone frequently requires a permit and an elevation check; the county floodplain administrator can say what applies.
