Weighing a property around Ainsworth? The Brown County flood zone map tells you whether FEMA puts it in a high-risk zone, and it costs nothing to check. This county guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the county gWorks map around Ainsworth.
Where the Brown County flood zone map lives
With a lot near Johnstown, the official source is FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. Vacant ground around Niobrara National Scenic River can still be found: search the nearest road then click the parcel area.
Opening the official parcel viewer
Your first stop is the Brown County gWorks map; it includes each tax parcel around Ainsworth and Long Pine. If you only know roughly where the land is, follow the nearest road on the aerial until the lines appear, then click inside the one you want, for land near Niobrara National Scenic River included. With a lot near Johnstown, write down the parcel ID before closing the panel; every clerk in the county asks for it first.
Before you lean on the lines
For a tract near Ainsworth, the acreage figure is an estimate; just a licensed surveyor can set the real boundary on the ground. For a tract near Johnstown, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
Beyond the mapped zones
Creeks and ditches near Johnstown aren't always studied in detail, so walk the land after rain. Marshy spots near Long Pine can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
Offices that can help
If the acreage or value on a parcel near Ainsworth looks off are handled by the County Assessor, which maintains the tax roll. Zoning, permits and septic questions near Ainsworth are for the local planning and health departments, and the answer depends on jurisdiction.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Niobrara National Scenic River, though signal can drop in rural spots. A screenshot of the parcel near Long Pine with its ID helps when you meet an owner or agent.
Reading A, AE and X
Zone AE carries a published BFE, which plain A zones lack; builders around Niobrara National Scenic River design to it. For a tract near Ainsworth, a shaded X area marks moderate flood hazard, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Getting your bearings
Ainsworth holds the county offices, home to the main records offices. Other places on the map include Long Pine, Johnstown, and Niobrara National Scenic River. About 2,853 people call Brown County home (Census Bureau estimate, 2023) across about 1,221 square miles. Brown County was formed in 1883, which matters when you trace an old farm's title. Features like Niobrara National Scenic River make handy reference points on the map.
Where the recorded documents are
Before you sign anything, request the recorded deed through the Register of Deeds; the parcel line is a drawing of it, which applies near Ainsworth as much as anywhere. If the land is near Long Pine, older tracts in the county may go back through many deeds, and a title company is worth hiring on a real sale.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so check the Brown County gWorks map too to see exactly which lot near Ainsworth you're looking at.
Insurance, lenders and building
For land near Ainsworth, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. New construction in a floodplain near Long Pine often needs a floodplain permit; ask the local floodplain administrator before you plan.
Legal descriptions in Nebraska
Nebraska is laid out under the Public Land Survey System, which means a tract near Ainsworth is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Johnstown odd-sized. Keep the legal description for land near Long Pine when you talk to a surveyor.
Questions to ask before you buy
Out toward Johnstown, request whether the home has flooded before closing; getting a quote early avoids surprises.

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.
