Before you buy or build near Orum, check the Washington County flood zone map: FEMA's zone label affects insurance, permits and resale. This county guide covers: finding the address on FEMA's map, decoding A, AE and X, and confirming the outline on the county map, at least around Arlington.
Getting started with the Washington County flood zone map
For parcel-by-parcel detail, try the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, for land near Fort Calhoun included. Rural land near Spiker with no street number is still easy to locate: search the nearest road and click inside the land.
The viewer Washington County publishes
Property in and around Blair can be looked up on the Washington County Beacon site, free to use and open without a login. Closer to De Soto, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near Spiker, save the parcel ID from that panel; each clerk in the county uses it to find the file.
What the zone letters mean
For land near De Soto, A and V zones are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. On ground around Herman, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, means minimal mapped risk.
Limits of the parcel data
For a tract near Boyer Chute National Wildlife Refuge, listed acreage is an estimate; just a licensed surveyor establishes the real lines on the ground. For a tract near Blair, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Getting your bearings
Blair serves as the county seat, which is where the courthouse records live. Other places on the map include Fort Calhoun, Arlington, Herman, and Kennard, each with its own cluster of lots. Roughly 21,152 people call Washington County home (Census estimate, 2023) spread over roughly 390 square miles. The county dates to 1854, which matters when you trace an old farm's title around Kennard. Features like Missouri River and Boyer Chute National Wildlife Refuge help you orient on the aerial.
Legal descriptions in Nebraska
Nebraska is laid out under the Public Land Survey System, so rural legal descriptions near DeSoto National Wildlife Refuge cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though corrections make some sections near Boyer Chute National Wildlife Refuge odd-sized. Write down the legal description for the tract near Orum for any title or survey request.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so pair it with the Washington County Beacon site to confirm you have the right parcel near Nashville.
What to request from a seller
For a home near Orum, request for any Elevation Certificate before closing; an insurance quote early keeps the budget honest.
What a flood zone means for a buyer
For a structure inside an A or V zone and the loan is federally backed or regulated, the lender will require flood insurance where the community participates in the National Flood Insurance Program, whether the land is near Spiker or elsewhere in the county. New construction in a floodplain near Arlington usually means extra permit review; call the permitting office early.
Backing up the map with records
For land near Fort Calhoun, the map is an index, not the title: deeds, plats and easements for parcels in the county are filed with the Register of Deeds. For a home near Nashville, have ready the instrument number shown in the record panel and the lookup takes minutes.
Next door to Washington County
Washington County meets Harrison County, IA, Pottawattamie County, IA, Burt County, Dodge County, and Douglas County, and each of those keeps its own parcel map. Acreage along the edge near De Soto may be split in two county records, so open the adjacent map before you assume the acreage. For a tract near Fort Calhoun, the Platbookmapper state page lists each bordering county map for Nebraska.
Water near De Soto
Small streams around De Soto aren't always studied in detail, so walk the land after rain. Wet ground around Nashville is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Frequently asked
Why did my flood zone near Blair change?
Generally, a new study can move a zone line near Herman; your community is notified before changes take effect.

Generally, look up the spot near De Soto in FEMA's National Flood Hazard Layer viewer; no account is needed.
How do I save a parcel from the viewer near De Soto?
