Where the Dayton flood zone map lives

City limits and county records
Dayton is part of Rhea County, Tennessee, which means parcel data comes from the county. Dayton is also the county seat, which puts the Register of Deeds close by. Closer to Spring City, the municipality handles things like zoning, permits and utilities within town limits, and the county still keeps the parcel and deed records. Lots just outside the town limits toward Spring City usually follows county rules instead.
Where the recorded documents are
Out toward Graysville, the map is an index, not the title: deeds, plats and easements for parcels in the county sit with the Register of Deeds. Older tracts around Graysville may sit on several deeds, and a title company can sort it out on a real sale.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Spring City, but coverage can be spotty out of town. A screenshot of the parcel near Graysville with its ID is a good backup.
Before you lean on the lines
The acreage figure is a tax-roll number; only a licensed surveyor establishes the real corners for a parcel near Spring City. For land near Graysville, records update in batches, so a deed recorded last month might lag behind.

Decoding the flood zone labels
Zone AE comes with a base flood elevation, and an unnumbered A zone has none; builders around Spring City design to it. Out toward Graysville, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so check the Tennessee Property Viewer too to see exactly which lot near Graysville you're looking at.
Low spots and local drainage
Low-lying fields near Graysville aren't always studied in detail, so walk the land after rain. Wet ground around Graysville is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
