Before you buy or build near Eddyville, look at the Lexington flood zone map: a mapped flood zone changes insurance, building rules and resale. This Lexington guide covers: locating a parcel on FEMA's map, reading the zone codes, and confirming the outline on the county map.
The Lexington flood zone map: start here
Start with FEMA's Flood Map Service Center: type an address near Gothenburg, and choose the dynamic map. A tract near Overton without an address is still easy to locate: pan from the closest town and click inside the land.
The free map to start with
The public parcel map for this area is the Dawson County gWorks map, and no login is needed to use it. If you're looking near Gothenburg, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. In and around Gothenburg, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Lexington and the county around it
Lexington sits in Dawson County, Nebraska, and the county assessor maps its lots. As the county seat, Lexington hosts the courthouse, so deeds and plats are filed in town. For a tract near Eddyville, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the town limits toward Gothenburg often follows county rules instead.
What the map can't tell you
Listed acreage is a tax-roll number; just a licensed surveyor can set the real lines for a parcel near Cozad. If the land is near Farnam, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Zones on the Lexington flood zone map
An AE label includes a base flood elevation (BFE), and an unnumbered A zone has none; builders around Gothenburg design to it. With a lot near Eddyville, minimal risk is not no risk: according to FEMA, floods happen outside mapped zones too.
Water near Gothenburg
Small streams around Eddyville aren't always studied in detail, so walk the land after rain. Wetlands near Overton can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Which office to call
If the acreage or value on a parcel near Cozad looks off belong with the County Assessor, since that office keeps the assessment data. Building or septic questions for a lot near Farnam go to planning, building or health offices, depending on whether the land is inside town limits.
Next door to Dawson County
Dawson County meets Buffalo County, Custer County, Frontier County, Gosper County, and Lincoln County, all with their own assessor records. Acreage along the edge near Farnam may show up across two assessors' files, so look at the neighboring map before you assume the acreage. In and around Cozad, the Platbookmapper state page links every bordering county map across Nebraska.
Questions to ask before you buy
Ask the seller about past flood claims on the property near Overton; an insurance quote early keeps the budget honest.
How land is described here
Nebraska uses the Public Land Survey System, which means a tract near Gothenburg is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though real sections near Eddyville vary in size. Write down the legal description for the tract near Farnam when you talk to a surveyor.
Parcel lines plus flood zones
FEMA's map shows zones but not ownership, so check the Dawson County gWorks map too to confirm you have the right parcel near Cozad.
Getting your bearings
Lexington is the county seat, which is where the courthouse records live. You'll also find Overton, Cozad, Sumner, and Eddyville, where town lots give way to larger tracts. Roughly 24,085 people live in Dawson County (Census estimate, 2023) on about 1,013 square miles.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Gothenburg are filed with the Register of Deeds. For a parcel near Cozad, have ready the book and page shown in the record panel so staff can find the deed fast.
Insurance, lenders and building
Around Cozad, get the Elevation Certificate if one exists: it can change the insurance price a lot. New construction in a floodplain near Cozad can trigger elevation rules; ask the local floodplain administrator early.
