Ahead of any purchase around Beaver, pull up the Boone County flood zone map: a mapped flood zone changes insurance, permits and resale. This Boone County guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the Boone County Beacon site.
Where the Boone County flood zone map lives
On ground around Madrid, flood zones come from FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. Vacant ground around Berkley can still be found: pan from the closest town then click the parcel area.
Getting to the right map
Your first stop is the Boone County Beacon site; it covers each tax parcel from Boxholm to Coal Valley. If the land is near Beaver, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. If the land is near Madrid, the record panel normally shows the owner of record, assessed acreage, the parcel number and sometimes recent sales.
When a parcel crosses a boundary
The county borders Dallas County, Greene County, Hamilton County, Polk County, and Story County, all with their own assessor records for land near Jordan. Ground near Angus that runs to the line can show up in two county records, so look at the adjacent map before you assume the acreage. Out toward Fraser, our state page links each bordering county map across Iowa.
On site with the map
Most viewers work in a phone browser, useful out on a road near Centerville, so load it before you lose signal. A saved image of the lot near Madrid and its lines is a good backup.
Sections, lots and bearings
Iowa uses the Public Land Survey System, so rural legal descriptions near Beaver cite section, township and range. Each section is nominally a mile square, about 640 acres, and a township holds 36 of them, though real sections near Beaver vary in size. Write down the legal description for the tract near Fraser before you request a deed or survey.
Zones on the Boone County flood zone map
If you're looking near Madrid, any A or V zone are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. For acreage around Madrid, minimal risk is not no risk: FEMA notes that floods happen outside mapped zones too.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so open the Boone County Beacon site next to see exactly which lot near Logansport you're looking at.
Limits of the parcel data
The acreage figure is a tax-roll number; only a licensed surveyor can set the real lines for a parcel near Angus. With a lot near Fraser, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Getting your bearings
Boone serves as the county seat, home to the main records offices. You'll also find Beaver, Berkley, Boxholm, and Fraser. Roughly 26,590 people call Boone County home (Census Bureau estimate, 2023) spread over roughly 570 square miles. The county was formed in 1846, which matters when you trace an old farm's title for land near Logansport.
Questions to ask before you buy
For a parcel near Jordan, ask the seller for any Elevation Certificate before closing; getting a quote early avoids surprises.
What a flood zone means for a buyer
For a parcel near Luther, get the Elevation Certificate if one exists: it compares the building to the BFE. Building or adding on near Fraser in a mapped zone usually means extra permit review; call the permitting office early.
Water near Madrid
Low-lying fields near Berkley may not have detailed mapping, so look for water marks and debris lines. Wet ground around Berkley is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Recorded documents worth pulling
For acreage around Angus, the map is an index, not the title: recorded deeds, plats and easements for parcels in the county are kept by the County Recorder. With a lot near Logansport, bring the book and page from the tax record so staff can find the deed fast.
Offices that can help
Anything recorded against property around Beaver are with the County Recorder, sometimes only in person. Questions about what you can build around Berkley go to planning, building or health offices, and the answer depends on jurisdiction.
