Weighing a property around Home? Checking the Marshall County flood zone map reveals whether it sits in a FEMA flood zone, and the lookup is free. What this Marshall County guide covers: the free FEMA tools, what each zone label means, lender insurance rules and what a LOMA is.
Where the Marshall County flood zone map lives
For land near Bremen, the official source is FEMA's Flood Map Service Center: enter the street address, and pick the FIRMette or map view. Vacant ground around Bremen can still be found: search the nearest road then click the parcel area.
Where the parcel data lives
Go first to the ORKA parcel viewer; it maps every assessed parcel in the county, Blue Rapids included. Without an address in hand, pan along the nearest road and select the outline, which applies near Lillis as much as anywhere. For a home near Marysville, save the parcel ID before closing the panel; each clerk in the county uses it to find the file.
Next door to Marshall County
Marshall County borders Nemaha County, Pottawatomie County, Riley County, Washington County, and Gage County, NE, all with their own assessor records. A tract near the line by Summerfield can show up across two assessors' files, so open the neighboring map before you assume the acreage. If you're looking near Blue Rapids, the Platbookmapper state page links each neighboring county map for Kansas.
A quick look at the area
Marysville is the county seat, which is where the courthouse records live. You'll also find Axtell, Beattie, Blue Rapids, and Frankfort, each with its own cluster of lots. About 9,933 people live in Marshall County (Census estimate, 2023) spread over some 900 square miles. The county dates to 1855, and some chains of title near Herkimer are long.
Offices that can help
For assessment questions about property around Blue Rapids go to the County Appraiser, the office behind the parcel record. Building or septic questions for a lot near Herkimer need the planning or permitting office, town or county, depending on location.
How land is described here
Kansas follows the Public Land Survey System, which means a tract near Marysville 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 corrections make some sections near Frankfort odd-sized. Write down the legal description for the tract near Summerfield before you request a deed or survey.
Before you lean on the lines
Around Frankfort, listed acreage is an estimate; just a licensed surveyor establishes the real boundary on the ground. For a tract near Lillis, records update in batches, so a deed recorded last month can take weeks to appear.
What to request from a seller
With a lot near Oketo, ask the seller whether the home has flooded before closing; getting a quote early avoids surprises.
Zones on the Marshall County flood zone map
On ground around Blue Rapids, A and V zones mark the Special Flood Hazard Area, which FEMA defines as a 1% annual chance of flooding. On ground around Summerfield, minimal risk is not no risk: FEMA notes that many claims come from moderate- and low-risk areas.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so check the ORKA parcel viewer too to confirm you have the right parcel near Herkimer.
Where the recorded documents are
Before you sign anything, pull the recorded deed through the Register of Deeds; the viewer just points to it, and that holds around Blue Rapids too. For acreage around Bremen, use the document number from the tax record and the lookup takes minutes.
Water near Blue Rapids
Creeks and ditches near Axtell may not have detailed mapping, so look for water marks and debris lines. Wet ground around Beattie is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Insurance, lenders and building
If a building sits in a Special Flood Hazard Area and the loan is federally backed or regulated, mandatory purchase rules apply in communities in the NFIP, which applies near Home as much as anywhere. New construction in a floodplain near Beattie often needs a floodplain permit; check with the county or town building office before you plan.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Beattie, but coverage can be spotty out of town. A printout of the tract near Lillis keeps working without signal.
Questions about the Marshall County flood zone map
What is a LOMA in Marshall County?
FEMA's LOMA process is the usual route when a building near Blue Rapids sits above the base flood elevation, and lenders accept the result.
Do I need to worry about flooding in Zone X around Blue Rapids?
In most cases, Zone X near Home means moderate (shaded) or minimal (unshaded) mapped risk; many owners near Frankfort buy coverage anyway.
What is the difference between Zone A and AE around Blue Rapids?
Both are high-risk zones, but only AE has a base flood elevation, so builders near Oketo design to that elevation.
Where do I find the BFE for a lot near Bremen?
Out toward Summerfield, the BFE is printed in AE zones on FEMA's map; local rules may require building above it.
Is there a way to export the map for land near Summerfield?
For a home near Marietta, some viewers offer PDF export; downloads of raw data vary by county.
