What the flood zone letters mean
On the FIRM covering Sumner 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 Goodlettsville means FEMA published a base flood elevation; plain Zone A means no detailed elevation was studied. Land near Goodlettsville in shaded X (Zone B on older maps) falls between the base flood and the 500-year flood. Unshaded Zone X near Goodlettsville is minimal risk.
Unmapped creeks in Sumner County
A low spot on a Sumner County tract outside any mapped zone can still flood; FEMA says moderate- and low-risk areas still carry risk.
Questions to ask before buying in Sumner County
Request any past flood claims history for a Sumner County property before closing; it tells you more than the map alone. Then call an insurance agent who writes policies around Gallatin and get a quote using the zone and the county parcel address.
Floodways and restudies near Mitchellville
When FEMA restudies streams in the county, preliminary maps are posted before they take effect, and a lot near Castalian Springs can move in or out of a zone. Floodways, shown as hatched areas on some panels, are the channel and nearby land that must stay open, and building there near Portland faces the strictest rules.
What a flood zone means for a Sumner County buyer
Here's why the zone matters at a closing in Hendersonville. When a structure near Goodlettsville sits in a Special Flood Hazard Area and secures a loan from a federally regulated or insured lender, flood insurance is mandatory, provided the community near Hendersonville takes part in the National Flood Insurance Program. Outside the A zones around Goodlettsville, federal rules do not require a policy, although some lenders require it anyway. When a county homesite is on a rise inside a mapped zone, a Letter of Map Amendment request is the formal route; a surveyor near Goodlettsville can supply the elevation data. Building or filling inside a mapped zone near Hendersonville typically needs a floodplain permit, so call the county or the town office in Hendersonville before work starts.
