Weighing a property around Marquette? The Hamilton County flood zone map tells you whether FEMA puts it in a high-risk zone, and it costs nothing to check. Covered here for Hamilton County: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Hamilton County gWorks map.
Where the Hamilton County flood zone map lives
For a parcel near Hampton, flood zones come from FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. A tract near Hordville without an address can still be found: zoom in from the nearest road and click the spot.
Getting to the right map
Your first stop is the Hamilton County gWorks map; it maps each assessed parcel in the county, Overland included. Without an address in hand, follow the nearest road on the aerial and click the parcel itself, and that holds around Hampton too. If you're looking near Phillips, write down the parcel ID from that panel; each office in the county asks for it first.
Low spots and local drainage
Creeks and ditches near Overland may not have detailed mapping, so look for water marks and debris lines. Wetlands near Stockham can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Reading A, AE and X
For a tract near Giltner, zones beginning with A or V are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. For a parcel near Giltner, a shaded X area is moderate risk, roughly the 100- to 500-year range; unshaded X is minimal risk.
Matching the zone to the lot lines
FEMA doesn't draw property lines, so open the Hamilton County gWorks map next to see exactly which lot near Hordville you're looking at.
A word on accuracy
For acreage around Phillips, listed acreage is an assessed number; just a licensed surveyor sets the real corners on the ground. Owner names and values update on a schedule, so a fresh transfer around Platte River may not show yet.
The paper trail behind a parcel
For anything that matters, get the recorded deed from the Register of Deeds; the viewer just points to it, and that holds around Hordville too. Inherited tracts near Phillips may go back through many deeds, and a title company can sort it out on a real sale.
Places you'll see on the map
Aurora is the county seat, which is where the courthouse records live. You'll also find Giltner, Hampton, Hordville, and Marquette, each with its own cluster of lots. Roughly 9,537 people live in the county (Census estimate, 2023) on roughly 542 square miles around Phillips. Hamilton County was organized in 1867, so old deeds can run back a long way. Features like Platte River help you orient on the aerial.
Which office to call
If the acreage or value on a parcel near Hordville looks off are handled by the County Assessor, the office behind the parcel record. Zoning, permits and septic questions near Hampton need the planning or permitting office, town or county, depending on location.
What a flood zone means for a buyer
If a building sits in a Special Flood Hazard Area and the loan is federally backed or regulated, flood insurance is generally required where the community participates in the National Flood Insurance Program, for land near Platte River included. Building or adding on near Overland in a mapped zone can trigger elevation rules; call the permitting office early.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Giltner, so load it before you lose signal. A saved image of the lot near Marquette and its lines is a good backup.
How land is described here
Nebraska uses the Public Land Survey System, which means a tract near Marquette is described by section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Hordville vary in size. Copy the legal description from the record for the parcel near Phillips before you request a deed or survey.
A short flood checklist
On ground around Marquette, ask the listing agent whether the home has flooded before closing; getting a quote early keeps the budget honest.
Frequently asked
How do I check the flood zone for an address in Hamilton County?
FEMA's free map shows the zone for any spot near Giltner, which takes a couple of minutes.
How do I get a property removed from a flood zone for land near Phillips?
It depends, but you can ask FEMA for a LOMA if surveyed elevations show the building near Platte River is above the BFE; it starts with an elevation survey.
What is the difference between Zone A and AE for land near Phillips?
Short answer: an AE zone has a 1% annual chance of flooding and a base flood elevation, so builders near Stockham design to that elevation.
Is Zone X safe from flooding near Stockham?
In most cases, Zone X near Marquette means moderate (shaded) or minimal (unshaded) mapped risk; many owners near Stockham buy coverage anyway.
Where do I ask about an assessment near Phillips?
For a tract near Marquette, the County Assessor handles values and the tax roll, and the Register of Deeds keeps deeds.

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.
