Before you buy or build near Bradford, pull up the Chickasaw County flood zone map: a mapped flood zone changes insurance, permits and resale. This county guide covers: locating a parcel on FEMA's map, reading the zone codes, and matching it with the county parcel viewer for land near Ionia.
Checking the Chickasaw County flood zone map step by step
Start with FEMA's Flood Map Service Center: type an address near Fredericksburg, and choose the dynamic map. Vacant ground around Nashua can still be found: zoom in from US Route 218 and click the spot.
Where the parcel data lives
Go first to the Chickasaw County Beacon site; it maps each tax parcel around Bassett and Deerfield. When a rural tract has no street number, follow US Route 218 on the aerial and select the outline, whether the land is near Boyd or elsewhere in the county. Closer to New Hampton, copy the parcel ID from that panel; each office in the county asks for it first.
Zones on the Chickasaw County flood zone map
For land near Bassett, zones beginning with A or V are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For land near Deerfield, a shaded X area marks moderate flood hazard, between the 1% and 0.2% annual chance floods; unshaded X means minimal mapped risk.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so check the Chickasaw County Beacon site too to confirm you have the right parcel near Little Turkey.
Next door to the county, at least around Bassett.
The county meets Bremer County, Butler County, Fayette County, Floyd County, and Howard County, and each of those keeps its own parcel map for land near Little Turkey. A tract near the line by Lawler can be split in two county records, so look at the adjacent map as well. If you're looking near Little Turkey, our state page links each neighboring county map for Iowa.
Recorded documents worth pulling
Before you sign anything, pull the recorded deed from the County Recorder; the viewer just points to it, and that holds around Bradford too. For land near Fredericksburg, have ready the book and page from the tax record so staff can find the deed fast.
Places you'll see on the map
New Hampton is the county seat, where most land records are kept. Other places on the map include Alta Vista, Bassett, Fredericksburg, and Ionia, each with its own cluster of lots. Around 11,658 people call Chickasaw County home (Census estimate, 2023) spread over some 504 square miles. Chickasaw County dates to 1851, which matters when you trace an old farm's title.
Getting answers from the right desk
If the acreage or value on a parcel near Fredericksburg looks off are handled by the County Assessor, which maintains the tax roll. Building or septic questions for a lot near Alta Vista go to planning, building or health offices, depending on whether the land is inside town limits.
How land is described here
Iowa uses the Public Land Survey System, so rural legal descriptions near Bradford cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Alta Vista odd-sized. Keep the legal description for land near Jerico for any title or survey request.
A short flood checklist
In and around Boyd, ask the seller whether the home has flooded before closing; getting a quote early keeps the budget honest.
What a flood zone means for a buyer
For a home near Bassett, get the Elevation Certificate if one exists: it compares the building to the BFE. Building or adding on near Boyd in a mapped zone often needs a floodplain permit; check with the county or town building office early.
Beyond the mapped zones
Creeks and ditches near Deerfield aren't always studied in detail, so ask neighbors about past flooding. Wet ground around Little Turkey is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Limits of the parcel data
Closer to Jerico, listed acreage is an estimate; only a licensed surveyor establishes the real corners on the ground. Owner names and values update on a schedule, so a recent sale near Lawler may not show yet.
Quick answers
What is a LOMA around Lawler?
On ground around Bradford, a Letter of Map Amendment (LOMA) from FEMA can remove a structure on naturally high ground, and lenders accept the result.
How do I check the flood zone for an address near Deerfield?
For most people, look up the spot near Little Turkey in FEMA's National Flood Hazard Layer viewer, and the zone code appears on the map.
Do I need flood insurance around Fredericksburg?

Do I need to worry about flooding in Zone X in Chickasaw County?
X zones around Little Turkey are lower risk, not no risk; FEMA notes that a large share of claims come from these areas.
Who keeps deeds for property around Fredericksburg?
