Getting oriented in Jackson County, TN
Gainesboro is the seat of Jackson County and the hub for its land records. Smaller places such as Dodson Branch, Center Grove, and Granville appear on the county map as little clusters of lots. Jackson County had an estimated 12,363 people in 2023 (Census Bureau), spread across about 309 square miles. Outside Center Grove, most of the county map is farm, ranch or timber ground with large, irregular tracts.
What the flood zone letters mean
For a lot in Dodson Branch, the label matters more than the color: A and V zones are Special Flood Hazard Areas, defined by a 1-percent annual chance of being flooded. Where a Jackson County tract displays Zone AE, there's a base flood elevation to compare a building against; in Zone A there is not one. Shaded Zone X around Dodson Branch is moderate risk, between the 1-percent and 0.2-percent annual chance lines. Unshaded Zone X near Gainesboro is minimal risk.

Low ground and small streams around Dodson Branch
Small streams and ditches near Dodson Branch may not be studied in detail, which is why it's worth walking the ground after a heavy rain.
Flood insurance and building rules in Jackson County
Here's why the zone matters at a closing in Dodson Branch. Where a building in Dodson Branch falls inside an A or V zone and carries a federally backed mortgage, flood insurance is mandatory under the Flood Disaster Protection Act, wherever the community joins the NFIP. For a county home in shaded or unshaded X, insurance is a choice, not a mandate; pricing a policy for land near Gainesboro is still worth a call. Where a structure near Dodson Branch looks higher than the shading suggests, the owner 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 Dodson Branch generally needs a floodplain permit, and the building office serving Gainesboro explains the steps.
