Weighing a property around Nelsonville? Checking the Athens County flood zone map reveals whether the lot falls inside a mapped floodplain, and it costs nothing to check. What this Athens County guide covers: the free FEMA tools, what each zone label means, when insurance is required and what a LOMA is.
Getting started with the Athens County flood zone map
For a more interactive look, open the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, for land near The Plains included. Rural land near Millfield with no street number can still be found: zoom in from the nearest road and click the spot.
Where the parcel data lives
Begin with the Athens County parcel viewer; it covers each assessed parcel in the county, Chauncey included. Without an address in hand, follow the nearest road on the aerial and select the outline, whether the land is near New Marshfield or elsewhere in the county. On ground around New Marshfield, save the parcel ID before closing the panel; every records desk in the county will want it.
A short flood checklist
For land near Hockingport, ask the listing agent for any Elevation Certificate before closing; an insurance quote early avoids surprises.
Zones on the Athens County flood zone map
For a home near Millfield, A and V zones mark the Special Flood Hazard Area, land with a 1-percent chance of flooding in any year. Around The Plains, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X is minimal risk.
Lining it up with the parcel map
FEMA doesn't draw property lines, so check the Athens County parcel viewer too to confirm you have the right parcel near Ohio River.
A word on accuracy
Acreage on the record is an assessed number; just a licensed surveyor can set the real corners on land around Nelsonville. For a tract near Nelsonville, records update in batches, so a deed recorded last month might lag behind.
Sections, lots and bearings
Older tracts around Chauncey are often described by metes and bounds, a series of courses and distances from a starting point. Platted lots around Millfield refer to a recorded plat, which is simpler to follow. Copy the legal description from the record for the parcel near Stewart for any title or survey request.
What a flood zone means for a buyer
For a structure inside an A or V zone and a federally regulated lender is involved, the lender will require flood insurance in communities in the NFIP, which applies near Amesville as much as anywhere. Building or adding on near Amesville in a mapped zone usually means extra permit review; ask the local floodplain administrator early.
On site with the map
Most viewers work in a phone browser, useful out on a road near Buchtel, though signal can drop in rural spots. A printout of the tract near Chauncey keeps working without signal.
Water near Stewart
Small streams around Millfield aren't always studied in detail, so look for water marks and debris lines. Wetlands near The Plains can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
