Weighing a property around Linwood? The Basehor flood zone map tells you whether it sits in a FEMA flood zone, and no account is needed. In this Basehor guide: finding the address on FEMA's map, reading the zone codes, and confirming the outline on the county map.
Getting started with the Basehor flood zone map
Flood zones come from FEMA's Flood Map Service Center: type an address near Lansing, and choose the dynamic map. Vacant ground around Bonner Springs can still be found: zoom in from the nearest road and click inside the land.
The viewer Leavenworth County publishes
Go first to the ORKA parcel viewer; it maps every tax parcel around Tonganoxie and Linwood. For a home near De Soto, put in a street address, an owner's name or a parcel number, then pick the result to center the map on it. Near Bonner Springs, the record panel normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
A short flood checklist
Ask the listing agent about past flood claims for the house near Linwood; an insurance quote early avoids surprises.
Places you'll see on the map
Leavenworth holds the county offices, home to the main records offices. You'll also find Bonner Springs, Lansing, Tonganoxie, and Linwood, each with its own cluster of lots. About 83,518 people call Leavenworth County home (Census estimate, 2023) spread over some 463 square miles. Leavenworth County was formed in 1855, and some chains of title near Linwood are long.
Where Basehor fits in
Basehor sits in Leavenworth County, Kansas, which means parcel data comes from the county. Closer to Linwood, the municipality handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Land beyond the city limits toward Lansing usually answers to county rules instead.
Reading A, AE and X
An AE label carries a published BFE, while plain Zone A does not; surveyors near Leavenworth use that number. For land near Leavenworth, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Next door to Leavenworth County
Leavenworth County touches Atchison County, Douglas County, Jefferson County, Johnson County, and Wyandotte County, all with their own assessor records. Ground near De Soto that runs to the line can be split in two county records, so check the neighboring map before you assume the acreage. For a home near Lansing, the Platbookmapper state page lists every bordering county map across Kansas.
Use the county map alongside FEMA
If only part of a parcel near Leavenworth is shaded, what matters is where the building sits.
A word on accuracy
Listed acreage is an estimate; only a licensed surveyor can set the real lines for a parcel near Linwood. Near Linwood, records update in batches, so a deed recorded last month can take weeks to appear.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Bonner Springs, but coverage can be spotty out of town. A printout of the tract near De Soto helps when you meet an owner or agent.
The paper trail behind a parcel
The map is an index, not the title: recorded deeds, plats and easements for land near Leavenworth are kept by the Register of Deeds. Out toward Lansing, have ready the document number from the tax record so staff can find the deed fast.
Which office to call
For assessment questions about property around Lansing belong with the County Appraiser, the office behind the parcel record. Questions about what you can build around Linwood go to planning, building or health offices, and the answer depends on jurisdiction.
What a flood zone means for a buyer
Out toward Tonganoxie, ask for an Elevation Certificate: it compares the building to the BFE. New construction in a floodplain near Lansing often needs a floodplain permit; check with the county or town building office before you plan.
Water near Leavenworth
Low-lying fields near Tonganoxie may not have detailed mapping, so ask neighbors about past flooding. Marshy spots near Leavenworth can limit building too; the National Wetlands Inventory mapper shows mapped wetlands.
