Before you buy or build near Keystone, pull up the Keith County flood zone map: the zone on that map shapes insurance, permits and resale. Covered here for the county: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the county gWorks map around Brule.
Getting started with the Keith County flood zone map
For a home near Lemoyne, flood zones come from FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. Vacant ground around Brule can still be found: zoom in from the nearest road and click the spot.
The viewer Keith County publishes
Begin with the Keith County gWorks map; it includes each assessed parcel around Roscoe and North Platte River. When a rural tract has no street number, pan along the nearest road and click the parcel itself, whether the land is near South Platte River or elsewhere in the county. For a home near Ogallala, the record panel normally shows the owner of record, assessed acreage, a parcel ID and often a sale date.
How land is described here
Nebraska is laid out under the Public Land Survey System, which means a tract near Brule is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Brule vary in size. Write down the legal description for the tract near Belmar when you talk to a surveyor.
The paper trail behind a parcel
If you're looking near Roscoe, the map is an index, not the title: deeds, subdivision plats and easements for parcels in the county are filed with the Register of Deeds. If you're looking near Belmar, have ready the document number shown in the record panel and the lookup takes minutes.
Zones on the Keith County flood zone map
For a parcel near Keystone, any A or V zone mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For acreage around Belmar, minimal risk is not no risk: according to FEMA, many claims come from moderate- and low-risk areas.
Which office to call
For assessment questions about property around Martin go to the County Assessor, since that office keeps the assessment data. Zoning, permits and septic questions near Paxton need the planning or permitting office, and the answer depends on jurisdiction.
Water near Lemoyne
Creeks and ditches near Belmar may not have detailed mapping, so look for water marks and debris lines. Wet ground around Lemoyne is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Land on the county line
Keith County touches Arthur County, Deuel County, Garden County, Lincoln County, and McPherson County; every one of them runs a separate parcel map. Ground near Belmar that runs to the line may be split in two county records, so check the adjacent map too. Out toward Ogallala, our state page links every bordering county map across Nebraska.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so check the Keith County gWorks map too to see exactly which lot near Paxton you're looking at.
Getting your bearings
Ogallala is the county seat, home to the main records offices. You'll also find Brule, Paxton, Belmar, and Keystone. Around 8,113 people live in Keith County (Census estimate, 2023) across some 1,062 square miles. The county dates to 1873, which matters when you trace an old farm's title around Lemoyne. Features like North Platte River and South Platte River make handy reference points on the map.
Before you lean on the lines
In and around North Platte River, listed acreage is an assessed number; only a licensed surveyor can set the real boundary on the ground. Closer to Keystone, records update in batches, so a deed recorded last month might lag behind.
A short flood checklist
On ground around Ogallala, ask the seller whether the home has flooded before closing; an insurance quote early avoids surprises.
What a flood zone means for a buyer
With a lot near Keystone, get the Elevation Certificate if one exists: it compares the building to the BFE. New construction in a floodplain near Belmar often needs a floodplain permit; call the permitting office before you plan.
Keith County: common questions
When is flood insurance required around South Platte River?
Short answer: lenders generally require it for buildings near Keystone in a Special Flood Hazard Area when the loan is federally regulated or insured; outside those zones it's your call.
Can I see flood zones on the county gWorks map near Belmar?
Good question; a flood layer may appear in the county gWorks map layer list, though it can lag behind FEMA's current panels, especially near Ogallala.
Where can I see the county flood zone map for free near Roscoe?
It depends, but search the address near South Platte River on FEMA's Flood Map Service Center, which takes a couple of minutes.
Is Zone X safe from flooding around Belmar?
Usually, shaded X is moderate risk and unshaded X is minimal risk; many owners near North Platte River buy coverage anyway.
Is there an app for the parcel map near North Platte River?
With a lot near Brule, no app is needed for most county viewers; screenshots help offline.

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.
