Before you buy or build near Alliance, look at the Box Butte County flood zone map: the zone on that map shapes insurance, permits and resale. What this Box Butte County guide covers: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Box Butte County parcel viewer.
The Box Butte County flood zone map: start here
For parcel-by-parcel detail, open the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, whether the land is near Letan or elsewhere in the county. A tract near Hemingford without an address is still easy to locate: zoom in from US Route 385 and click inside the land.
Opening the official parcel viewer
Your first stop is the Box Butte County parcel viewer; it covers every tax parcel around Nonpareil and Berea. If you only know roughly where the land is, follow US Route 385 on the aerial and select the outline, for land near Nonpareil included. With a lot near Berea, save the parcel ID before closing the panel; every office in the county asks for it first.
Box Butte County in a few facts
Alliance serves as the county seat, where most land records are kept. Other places on the map include Hemingford, Berea, Letan, and Nonpareil. Around 10,692 people call Box Butte County home (Census estimate, 2023) spread over some 1,075 square miles. The county was organized in 1886, so old deeds can run back a long way around Letan.
A short flood checklist
For property near Hemingford, ask the seller for any Elevation Certificate before closing; an insurance quote early keeps the budget honest.
Limits of the parcel data
Acreage on the record is an estimate; only a licensed surveyor establishes the real corners for a parcel near Berea. Closer to Berea, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Decoding the flood zone labels
For acreage around Letan, zones beginning with A or V are Special Flood Hazard Areas, meaning a 1% or greater chance of flooding each year. For a home near Berea, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Matching the zone to the lot lines
Where a floodplain cuts across acreage near Alliance, what matters is where the building sits.
Neighboring parcel maps
Box Butte County meets Dawes County, Morrill County, Scotts Bluff County, Sheridan County, and Sioux County, and each of those keeps its own parcel map. Ground near Nonpareil that runs to the line can be split across two assessors' files, so look at the adjacent map too. If the land is near Letan, the Platbookmapper state page links every neighboring county map for Nebraska.
Insurance, lenders and building
For a tract near Letan, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Building or adding on near Alliance in a mapped zone usually means extra permit review; call the permitting office early.
Which office to call
For assessment questions about property around Alliance are handled by the County Assessor, the office behind the parcel record. Building or septic questions for a lot near Berea need the planning or permitting office, and the answer depends on jurisdiction.
How land is described here
Nebraska uses the Public Land Survey System, so rural legal descriptions near Hemingford cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Berea odd-sized. Keep the legal description for land near Letan for any title or survey request.
Beyond the mapped zones
Low-lying fields near Alliance aren't always studied in detail, so ask neighbors about past flooding. Marshy spots near Nonpareil can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Taking the map into the field
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Nonpareil, but coverage can be spotty out of town. A saved image of the lot near Berea and its lines helps when you meet an owner or agent.
Quick answers

Out toward Letan, a Letter of Map Amendment (LOMA) from FEMA can remove a structure on naturally high ground, and lenders accept the result.
Do I need to worry about flooding in Zone X around Nonpareil?
Generally, X zones around Nonpareil are lower risk, not no risk; FEMA notes that a large share of claims come from these areas.
Where can I see the county flood zone map for free near Nonpareil?
Generally, look up the spot near Nonpareil in FEMA's National Flood Hazard Layer viewer; then confirm the parcel on the county viewer.
Will my lender require flood insurance near Letan?
For a home near Alliance, it's typically required only for structures in high-risk zones with federally backed loans; outside those zones it's your call.
