Ahead of any purchase around Bolan, pull up the Worth County flood zone map: FEMA's zone label affects insurance, permits and resale. Covered here for Worth County: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Worth County Beacon site.
Getting started with the Worth County flood zone map
If you'd rather pan and zoom, try the National Flood Hazard Layer viewer, where zone shading sits over a photo base, which applies near Joice as much as anywhere. A tract near Fertile without an address can still be found: pan from the closest town and click inside the land.
Getting to the right map
Begin with the Worth County Beacon site; it includes each assessed parcel in the county, Fertile included. Without an address in hand, pan along the nearest road and select the outline, and that holds around Northwood too. Out toward Hanlontown, the parcel card normally shows the owner of record, acreage on the tax roll, the parcel number and often a sale date.
Water near Manly
Low-lying fields near Fertile may not have detailed mapping, so ask neighbors about past flooding. Wet ground around Bolan is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Legal descriptions in Iowa
Iowa uses the Public Land Survey System, which means a tract near Hanlontown is described by 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 Manly vary in size. Write down the legal description for the tract near Grafton before you request a deed or survey.
Deeds, plats and who keeps them
Before you sign anything, pull the recorded deed through the County Recorder; the viewer just points to it, which applies near Northwood as much as anywhere. Out toward Kensett, bring the document number from the tax record to skip a name search.
Before you lean on the lines
For land near Fertile, the acreage figure is an estimate; only a licensed surveyor can set the real boundary on the ground. For a home near Bolan, records update in batches, so a deed recorded last month might lag behind.
When a parcel crosses a boundary
The county borders Cerro Gordo County, Hancock County, Mitchell County, Winnebago County, and Freeborn County, MN, and each of those keeps its own parcel map for land near Northwood. A tract near the line by Fertile can show up across two assessors' files, so look at the adjacent map as well. For a tract near Manly, the Platbookmapper state page lists every bordering county map across Iowa.
What to request from a seller
For property near Hanlontown, ask the seller about past flood claims before closing; getting a quote early avoids surprises.
Reading A, AE and X
Zone AE includes a base flood elevation (BFE), and an unnumbered A zone has none; builders around Manly design to it. For land near Grafton, a shaded X area marks moderate flood hazard, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Offices that can help
Deeds, mortgages and recorded plats for land near Grafton come from the County Recorder, often with an online index. Questions about what you can build around Northwood need the planning or permitting office, depending on whether the land is inside town limits.
Lining it up with the parcel map
FEMA doesn't draw property lines, so pair it with the Worth County Beacon site to confirm you have the right parcel near Fertile.
Worth County in a few facts
Northwood is the county seat, where most land records are kept. Other places on the map include Fertile, Grafton, Hanlontown, and Joice, where town lots give way to larger tracts. Roughly 7,297 people live in the county (Census Bureau estimate, 2023) on about 400 square miles for land near Northwood. The county dates to 1851, which matters when you trace an old farm's title around Joice.
Insurance, lenders and building
If the land is near Northwood, get the Elevation Certificate if one exists: it records the building's elevation against the base flood. Building or adding on near Kensett in a mapped zone often needs a floodplain permit; check with the county or town building office before you plan.
Quick answers
Why did my flood zone near Kensett change?
For acreage around Northwood, FEMA revises flood maps panel by panel as new studies finish; your community is notified before changes take effect.
How can I tell if a house near Grafton is in a flood zone?
Good question; search the address near Kensett on FEMA's Flood Map Service Center; no account is needed.
What is the difference between Zone A and AE for land near Bolan?
For a tract near Fertile, an AE zone has a 1% annual chance of flooding and a base flood elevation; unnumbered A zones don't list one.
Is Zone X safe from flooding in Worth County?
It depends, but Zone X near Joice means moderate (shaded) or minimal (unshaded) mapped risk; many owners buy coverage anyway.
Is the parcel map a survey around Fertile?
For property near Fertile, parcel lines are tax drawings, not surveys.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
