Weighing a property around Pender? A quick look at the Thurston County flood zone map shows whether it sits in a FEMA flood zone, and the lookup is free. In this Thurston County guide: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Thurston County gWorks map.
The Thurston County flood zone map: start here
For a more interactive look, use the National Flood Hazard Layer viewer, which draws the zones over aerial imagery, whether the land is near Winnebago or elsewhere in the county. Rural land near Rosalie with no street number is still easy to locate: zoom in from the nearest road and click the spot.
Pulling up a parcel
Property in and around Macy can be looked up on the Thurston County gWorks map, a viewer that needs no account. When a rural tract has no street number, follow the nearest road on the aerial until the lines appear, then click inside the one you want, and that holds around Emerson too. With a lot near Missouri River, save the parcel ID while you have it open; each office in the county uses it to find the file.
The paper trail behind a parcel
For anything that matters, request the recorded deed from the Register of Deeds; the parcel line is a drawing of it, whether the land is near Walthill or elsewhere in the county. If the land is near Emerson, use the document number shown in the record panel so staff can find the deed fast.
Low spots and local drainage
Low-lying fields near Emerson may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Missouri River can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Reading A, AE and X
With a lot near Pender, any A or V zone are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. For a parcel near Macy, shaded Zone X is moderate risk, roughly the 100- to 500-year range; plain X, or C on older maps, means minimal mapped risk.
When a parcel crosses a boundary
The county borders Monona County, IA, Woodbury County, IA, Burt County, Cuming County, and Dakota County; every one of them runs a separate parcel map, especially near Missouri River. Acreage along the edge near Walthill may be split across two assessors' files, so look at the neighboring map before you assume the acreage. In and around Macy, our state page links each neighboring county map for Nebraska.
A word on accuracy
Around Rosalie, the acreage figure is an estimate; just a licensed surveyor can set the real corners on the ground. For land near Winnebago, records update in batches, so a deed recorded last month may not show yet.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so pair it with the Thurston County gWorks map to confirm you have the right parcel near Emerson.
How land is described here
Nebraska follows the Public Land Survey System, so rural legal descriptions near Winnebago cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Pender odd-sized. Keep the legal description for land near Winnebago before you request a deed or survey.
On site with the map
The parcel map usually runs in a mobile browser, useful out on a road near Rosalie, though signal can drop in rural spots. A screenshot of the parcel near Winnebago with its ID is a good backup.
Getting your bearings
Pender is the county seat, where most land records are kept. You'll also find Emerson, Rosalie, Walthill, and Winnebago, each with its own cluster of lots. About 6,557 people live in Thurston County (Census Bureau estimate, 2023) across roughly 394 square miles. The county was formed in 1889, and some chains of title near Pender are long. Features like Missouri River make handy reference points on the map.
What a flood zone means for a buyer
For property near Emerson, ask for an Elevation Certificate: it compares the building to the BFE. Building or adding on near Walthill in a mapped zone can trigger elevation rules; check with the county or town building office before you plan.
What to request from a seller
Ask the seller about past flood claims on the property near Emerson; getting a quote early avoids surprises.
Quick answers
What does Zone AE mean near Rosalie?
Short answer: AE is a Special Flood Hazard Area with a published base flood elevation, so builders near Macy design to that elevation.
Will my lender require flood insurance near Pender?
In and around Macy, it's typically required only for structures in high-risk zones with federally backed loans; elsewhere it's optional.
How often are flood maps updated around Pender?
In most cases, zones near Missouri River can shift when FEMA updates a panel; check the effective date on the panel.
What is a LOMA in Thurston County?
In most cases, FEMA's LOMA process is the usual route when a building near Emerson sits above the base flood elevation; it starts with an elevation survey.
Can I use the viewer in the field near Rosalie?
If the land is near Emerson, no app is needed for most county viewers, though rural signal can drop.

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.
