Before you buy or build near Fort Calhoun, pull up the Blair flood zone map: FEMA's zone label affects insurance, permits and resale. This Blair guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the county Beacon site.
Getting started with the Blair flood zone map
The official source is FEMA's Flood Map Service Center: type an address near Herman, and choose the dynamic map. Rural land near Washington with no street number can still be found: zoom in from the nearest road and click the spot.
Where the parcel data lives
Your first stop is the Washington County Beacon site; it maps every assessed parcel around Fort Calhoun and Washington. Closer to Fort Calhoun, type a street address, an owner's name or a parcel number, and the matching parcel lights up. On ground around Fort Calhoun, write down the parcel ID before closing the panel; every records desk in the county will want it.
City limits and county records
Blair sits in Washington County, Nebraska, and the county assessor maps its lots. As the county seat, Blair hosts the courthouse, handy when you need recorded documents. Closer to Fort Calhoun, the municipality handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits near Arlington often falls under county rules instead.
Reading A, AE and X
On ground around Arlington, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For property near Fort Calhoun, a low-risk label isn't a guarantee: FEMA notes that many claims come from moderate- and low-risk areas.
Field tips
Most viewers work in a phone browser, useful out on a road near Kennard, so load it before you lose signal. A screenshot of the parcel near Kennard with its ID keeps working without signal.
Water near Washington
Low-lying fields near Kennard may not have detailed mapping, so ask neighbors about past flooding. Wet ground around Fort Calhoun is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
What to request from a seller
Ask the seller about past flood claims for the house near Fort Calhoun; an insurance quote early keeps the budget honest.
A word on accuracy
Acreage on the record is an assessed number; only a licensed surveyor sets the real lines on land around Herman. On ground around Washington, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so open the Washington County Beacon site next to confirm you have the right parcel near Arlington.
Lenders and permits
For land near Arlington, get the Elevation Certificate if one exists: it can change the insurance price a lot. Building or adding on near Fort Calhoun in a mapped zone often needs a floodplain permit; ask the local floodplain administrator early.
Washington County in a few facts
Blair serves as the county seat, home to the main records offices. Other places on the map include Kennard, Fort Calhoun, Herman, and Washington, where town lots give way to larger tracts. Roughly 21,152 people live in Washington County (Census Bureau estimate, 2023) on roughly 390 square miles. Washington County was organized in 1854, so old deeds can run back a long way. Features like Missouri River and Boyer Chute National Wildlife Refuge are easy to spot when you zoom out from Arlington.
Neighboring parcel maps
The county touches Harrison County, IA, Pottawattamie County, IA, Burt County, Dodge County, and Douglas County, and each of those keeps its own parcel map. A tract near the line by Fort Calhoun may be split in two county records, so look at the neighboring map as well. Near Washington, the Platbookmapper state page lists every bordering county map for Nebraska.
Offices that can help
If the acreage or value on a parcel near Herman looks off go to the County Assessor, the office behind the parcel record. Questions about what you can build around Herman need the planning or permitting office, depending on whether the land is inside town limits.
Quick answers
Can I see flood zones on the Washington County Beacon site?
Good question; a flood layer may appear in the Washington County Beacon site layer list, but FEMA's own map is the official source.
What is a LOMA for land near Fort Calhoun?
You can ask FEMA for a LOMA if surveyed elevations show the building near Herman is above the BFE; a surveyor's elevation data supports it.
How often are flood maps updated for land near Kennard?
Good question; zones near Herman can shift when FEMA updates a panel; your community is notified before changes take effect.
When is flood insurance required for land near Arlington?
Short answer: lenders generally require it for buildings near Herman in a Special Flood Hazard Area when the loan is federally regulated or insured; outside those zones it's your call.
Is the parcel map a survey in Blair?
No; boundary questions near Fort Calhoun need a licensed surveyor; a survey sets the real corners

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
