Weighing a property around Dunbar? A quick look at the Otoe County flood zone map shows whether FEMA puts it in a high-risk zone, and no account is needed. What this Otoe County guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and matching it with the county parcel viewer.
Getting started with the Otoe County flood zone map
If you'd rather pan and zoom, use the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, whether the land is near Woodland Hills or elsewhere in the county. Rural land near Syracuse with no street number is still easy to locate: zoom in from the nearest road and click the spot.
Where the parcel data lives
Go first to the Otoe County gWorks map; it covers every assessed parcel from Douglas to Nebraska City. Without an address in hand, follow the nearest road on the aerial and click the parcel itself, for land near Woodland Hills included. In and around Syracuse, copy the parcel ID from that panel; each office in the county will want it.
Decoding the flood zone labels
For a parcel near Syracuse, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. Out toward Dunbar, shaded Zone X marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
What to request from a seller
Out toward Lorton, ask the listing agent for any Elevation Certificate before closing; an insurance quote early avoids surprises.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so check the Otoe County gWorks map too to confirm you have the right parcel near Dunbar.
A quick look at the area
Nebraska City serves as the county seat, which is where the courthouse records live. You'll also find Syracuse, Burr, Douglas, and Dunbar, where town lots give way to larger tracts. Roughly 16,335 people call Otoe County home (Census Bureau estimate, 2023) across some 616 square miles. Otoe County was organized in 1855, so old deeds can run back a long way. Features like Missouri River make handy reference points on the map near Lorton.
Taking the map into the field
The parcel map usually runs in a mobile browser, useful out on a road near Dunbar, so load it before you lose signal. A saved image of the lot near Douglas and its lines is a good backup.
Water near Missouri River
Small streams around Lorton aren't always studied in detail, so look for water marks and debris lines. Marshy spots near Burr can limit building too; check the National Wetlands Inventory mapper for a first look.
Deeds, plats and who keeps them
When the details count, pull the recorded deed from the Register of Deeds; the parcel line is a drawing of it, and that holds around Douglas too. For land near Woodland Hills, have ready the book and page listed on the parcel record to skip a name search.
Offices that can help
Questions about value or the owner field for land near Lorton belong with the County Assessor, since that office keeps the assessment data. Zoning, permits and septic questions near Nebraska City need the planning or permitting office, depending on whether the land is inside town limits.
Limits of the parcel data
For land near Syracuse, listed acreage is an assessed number; just a licensed surveyor establishes the real boundary on the ground. For a tract near Syracuse, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Insurance, lenders and building
Closer to Burr, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Building or adding on near Douglas in a mapped zone can trigger elevation rules; check with the county or town building office before you plan.
Land on the county line
Otoe County touches Fremont County, IA, Atchison County, MO, Cass County, Gage County, and Johnson County; every one of them runs a separate parcel map. Acreage along the edge near Nebraska City can be split in two county records, so check the neighboring map too. For a tract near Woodland Hills, our state page links each neighboring county map across Nebraska.

In most cases, X zones around Missouri River are lower risk, not no risk, and floods still happen outside high-risk zones.
What is a base flood elevation for land near Burr?

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.
