Before you buy or build near Annawan, check the Kewanee flood zone map: a mapped flood zone changes insurance, permits and resale. What this Kewanee guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Henry County WTH GIS map.
The Kewanee flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: search an address around Annawan, and choose the dynamic map. Vacant ground around Geneseo is still easy to locate: zoom in from Interstate 280 and click inside the land.
Opening the official parcel viewer
Go first to the Henry County WTH GIS map; it maps each assessed parcel in the county, Atkinson included. If you only know roughly where the land is, pan along Interstate 280 and select the outline. On ground around Bishop Hill, a pop-up or side panel typically gives the owner of record, assessed acreage, the parcel number and often a sale date.
What to request from a seller
Ask the seller about past flood claims for the house near Annawan; getting a quote early avoids surprises.
City limits and county records
Kewanee is part of Henry County, Illinois, so its parcels are on the county's map. If the land is near Galva, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, while the county keeps the tax map. Lots just outside the city limits near Galva often follows county rules, not municipal ones.
Sections, lots and bearings
Illinois uses the Public Land Survey System, which means a tract near Galva 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 Galva vary in size. Write down the legal description for the tract near Annawan when you talk to a surveyor.
Zones on the Kewanee flood zone map
For a parcel near Geneseo, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. For a tract near Bishop Hill, a low-risk label isn't a guarantee: FEMA notes that many claims come from moderate- and low-risk areas.
The paper trail behind a parcel
When the details count, get the recorded deed from the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Galva only summarizes it. Long-held tracts near Galva can go back through a long string of deeds, so a title company earns its fee on a real sale.
Water near Bishop Hill
Creeks and ditches near Annawan may not have detailed mapping, so ask neighbors about past flooding. Wet ground around Galva is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Limits of the parcel data
The acreage figure is a tax-roll number; just a licensed surveyor can set the real corners for a parcel near Annawan. For a home near Annawan, owner names and values update on a schedule, so a deed recorded last month may not show yet.
On site with the map
Most viewers work in a phone browser, which helps when you're standing on land near Geneseo, so load it before you lose signal. A printout of the tract near Geneseo is a good backup.
Lining it up with the parcel map
FEMA doesn't draw property lines, so open the Henry County WTH GIS map next to see exactly which lot near Annawan you're looking at.
Places you'll see on the map
Cambridge is the county seat, which is where the courthouse records live. Smaller places on the map include Galva, Bishop Hill, Annawan, and Atkinson. Around 48,448 people call Henry County home (Census Bureau estimate, 2023) on roughly 823 square miles. Henry County was formed in 1825, and some chains of title near Annawan are long.
Lenders and permits
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, flood insurance is generally required where the community participates in the National Flood Insurance Program, whether the land is near Atkinson or elsewhere in the county. Building or adding on near Geneseo in a mapped zone usually means extra permit review; call the permitting office early.
Kewanee: common questions
Is AE a high-risk flood zone in Kewanee?
Good question; an AE zone has a 1% annual chance of flooding and a base flood elevation, which shapes building rules near Bishop Hill.
What is a LOMA near Galva?
Short answer: FEMA's LOMA process is the usual route when a building near Atkinson sits above the base flood elevation; it starts with an elevation survey.
How do I check the flood zone for an address in Kewanee?
Look up the spot near Annawan in FEMA's National Flood Hazard Layer viewer, which takes a couple of minutes.
What is a base flood elevation in Kewanee?
Short answer: a BFE near Atkinson tells builders how high the lowest floor should be, and an Elevation Certificate compares the building to it.
Where do I ask about an assessment near Cambridge?
For land near Annawan, assessment goes to the Supervisor of Assessments, working with township assessors and deeds to the county Recorder of Deeds (in many counties the County Clerk and Recorder); planning offices cover zoning near Bishop Hill
