Weighing a property around Eddyville? Checking the Ottumwa flood zone map reveals whether it sits in a FEMA flood zone, and no account is needed. Covered here for Ottumwa: locating a parcel on FEMA's map, reading the zone codes, and pairing it with the Wapello County Beacon site.
The Ottumwa flood zone map: start here
Start with FEMA's Flood Map Service Center: search an address around Eldon, then open the map view for that panel. Rural land near Eddyville with no street number can still be found: zoom in from the nearest road and click the spot.
The viewer Wapello County publishes
Begin with the Wapello County Beacon site; it maps every tax parcel from Agency to Chillicothe. Without an address in hand, pan along the nearest road until the lines appear, then click inside the one you want, whether the land is near Chillicothe or elsewhere in the county. If the land is near Blakesburg, the record panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
A word on accuracy
Parcel lines are drawn for taxes, not surveyed, so a tree line near Kirkville often sits several feet off the line on screen. For a parcel near Kirkville, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Low spots and local drainage
Low-lying fields near Eddyville aren't always studied in detail, so ask neighbors about past flooding. Wetlands near Chillicothe can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
Getting your bearings
Ottumwa is the county seat, where most land records are kept. Smaller places on the map include Agency, Chillicothe, Kirkville, and Blakesburg. Roughly 35,166 people live in Wapello County (Census Bureau estimate, 2023) on roughly 432 square miles. Wapello County was formed in 1843, so old deeds can run back a long way.
Which office to call
Deeds, mortgages and recorded plats for land near Agency sit in the index kept by the County Recorder, sometimes only in person. Building or septic questions for a lot near Kirkville need the planning or permitting office, and the answer depends on jurisdiction.
Legal descriptions in Iowa

Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Chillicothe vary in size. Copy the legal description from the record for the parcel near Blakesburg for any title or survey request.
Ottumwa, IA: the basics
Ottumwa is part of Wapello County, Iowa, so its parcels are on the county's map. As the county seat, Ottumwa hosts the courthouse, which puts the County Recorder close by. For a parcel near Eldon, city or town hall handles things like zoning, permits and utilities for lots inside the boundary, and the county still keeps the parcel and deed records. Lots just outside the town limits out by Eddyville usually follows county rules rather than the town's.
Decoding the flood zone labels
On ground around Kirkville, 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 Kirkville, a low-risk label isn't a guarantee: FEMA notes that many claims come from moderate- and low-risk areas.
Recorded documents worth pulling
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Eddyville sit with the County Recorder. If you're looking near Kirkville, have ready the instrument number shown in the record panel so staff can find the deed fast.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so pair it with the Wapello County Beacon site to see exactly which lot near Agency you're looking at.
A short flood checklist
Request whether the home has flooded on the property near Blakesburg; an insurance quote early avoids surprises.
Insurance, lenders and building
For a structure inside an A or V zone and the loan is federally backed or regulated, the lender will require flood insurance where the community participates in the National Flood Insurance Program, whether the land is near Agency or elsewhere in the county. Building or adding on near Agency in a mapped zone can trigger elevation rules; check with the county or town building office before you plan.
