Before you buy or build near Basehor, check the Leavenworth flood zone map: FEMA's zone label affects insurance, permits and resale. What this Leavenworth guide covers: finding the address on FEMA's map, reading the zone codes, and matching it with the county parcel viewer.
The Leavenworth flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: type an address near Tonganoxie, and pick the FIRMette or map view. Vacant ground around De Soto is still easy to locate: zoom in from the nearest road then click the parcel area.
The free map to start with
Go first to the ORKA parcel viewer; it maps every assessed parcel from Tonganoxie to Easton. If you're looking near Basehor, type a street address, an owner's name or a parcel number, and the matching parcel lights up. For land near Basehor, a pop-up or side panel normally shows the owner of record, assessed acreage, a parcel ID and often a sale date.
A quick look at the area
Leavenworth serves as the county seat, home to the main records offices. Smaller places on the map include Lansing, Easton, Basehor, and Tonganoxie. Roughly 83,518 people live in Leavenworth County (Census Bureau estimate, 2023) spread over some 463 square miles. Leavenworth County was formed in 1855, so old deeds can run back a long way.
Legal descriptions in Kansas
Kansas follows the Public Land Survey System, so rural legal descriptions near Lansing cite section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Lansing vary in size. Keep the legal description for land near Easton when you talk to a surveyor.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Tonganoxie, so load it before you lose signal. A screenshot of the parcel near Basehor with its ID is a good backup.
City limits and county records
Leavenworth sits in Leavenworth County, Kansas, and the county assessor maps its lots. As the county seat, Leavenworth hosts the courthouse, so deeds and plats are filed in town. If you're looking near De Soto, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Lots just outside the city limits out by Lansing generally answers to county rules instead.
Zones on the Leavenworth flood zone map
An AE label comes with a base flood elevation, and an unnumbered A zone has none; surveyors near Lansing use that number. Around Basehor, a low-risk label isn't a guarantee: FEMA notes that many claims come from moderate- and low-risk areas.
Neighboring parcel maps
Leavenworth County touches Atchison County, Douglas County, Jefferson County, Johnson County, and Wyandotte County, and each of those keeps its own parcel map. Ground near Bonner Springs that runs to the line may show up in two county records, so check the adjacent map as well. On ground around De Soto, our state page links each bordering county map across Kansas.
Offices that can help
Anything recorded against property around De Soto sit in the index kept by the Register of Deeds, sometimes only in person. Building or septic questions for a lot near Lansing need the planning or permitting office, and the answer depends on jurisdiction.
Beyond the mapped zones
Low-lying fields near Lansing may not have detailed mapping, so ask neighbors about past flooding. Wetlands near Lansing can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Limits of the parcel data
Acreage on the record is an assessed number; only a licensed surveyor sets the real corners for a parcel near Bonner Springs. If you're looking near De Soto, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so pair it with the ORKA parcel viewer to confirm you have the right parcel near Easton.
Questions to ask before you buy
Ask the seller for any Elevation Certificate for the house near Lansing; getting a quote early keeps the budget honest.
What a flood zone means for a buyer
On ground around Tonganoxie, get the Elevation Certificate if one exists: it compares the building to the BFE. New construction in a floodplain near Easton can trigger elevation rules; call the permitting office early.
