Before you buy or build near Clarkson, look at the Warren County flood zone map: a mapped flood zone changes insurance, building rules and resale. This Warren County guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Warren County Beacon site.
Where the Warren County flood zone map lives
For a more interactive look, use the National Flood Hazard Layer viewer, where zone shading sits over a photo base, whether the land is near Cumming or elsewhere in the county. Vacant ground around Des Moines can still be found: zoom in from the nearest road then click the parcel area.
Getting to the right map
Go first to the Warren County Beacon site; it covers each assessed parcel around Conger and Cumming. Without an address in hand, follow the nearest road on the aerial until the lines appear, then click inside the one you want, whether the land is near Hartford or elsewhere in the county. For a parcel near Des Moines, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and often a sale date.
How land is described here
Iowa is laid out under the Public Land Survey System, which means a tract near Cool is described by section, township and range. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though real sections near Des Moines vary in size. Keep the legal description for land near Des Moines for any title or survey request.
Deeds, plats and who keeps them
The map is an index, not the title: deeds, subdivision plats and easements for land near Hartford sit with the County Recorder. Long-held tracts around Ford may sit on several deeds, and a title company is worth hiring before a purchase.
What the zone letters mean
For a home near Clarkson, A and V zones are Special Flood Hazard Areas, which FEMA defines as a 1% annual chance of flooding. For a parcel near Des Moines, shaded Zone X is moderate risk, roughly the 100- to 500-year range; unshaded X means minimal mapped risk.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the Warren County Beacon site too for the outline of the tract near Bevington.
A short flood checklist
For a tract near Des Moines, request for any Elevation Certificate before closing; getting a quote early avoids surprises.
Low spots and local drainage
Creeks and ditches near Carlisle may not have detailed mapping, so look for water marks and debris lines. Wetlands near Des Moines can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
A quick look at the area
Indianola serves as the county seat, where most land records are kept. You'll also find Ackworth, Bevington, Carlisle, and Cumming, where town lots give way to larger tracts. About 55,205 people call Warren County home (Census estimate, 2023) on about 570 square miles. The county was formed in 1846, so old deeds can run back a long way around Carlisle.
Who handles what
If the acreage or value on a parcel near Conger looks off are handled by the County Assessor, the office behind the parcel record. Zoning, permits and septic questions near Cool go to planning, building or health offices, town or county, depending on location.
What a flood zone means for a buyer
Closer to Indianola, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. Building or adding on near Bevington in a mapped zone often needs a floodplain permit; call the permitting office before you plan.
A word on accuracy
With a lot near Carlisle, the acreage figure is an estimate; only a licensed surveyor can set the real lines on the ground. If you're looking near Clarkson, records update in batches, so a deed recorded last month can take weeks to appear.
Using it on a phone
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Ackworth, though signal can drop in rural spots. A screenshot of the parcel near Ackworth with its ID keeps working without signal.
Quick answers
What does an AE label mean for a lot near Des Moines?
In and around Ford, both are high-risk zones, but only AE has a base flood elevation; unnumbered A zones don't list one.
Does the county parcel map show flood zones around Des Moines?
Usually, a flood layer may appear in the Warren County Beacon site layer list, but FEMA's own map is the official source.
Is my property near Beech in a flood zone?
In most cases, FEMA's free map shows the zone for any spot near Beech; no account is needed.
What is a LOMA near Des Moines?
If the land is near Hartford, a Letter of Map Amendment (LOMA) from FEMA can remove a structure on naturally high ground; a surveyor's elevation data supports it.
Does the parcel map work on a phone around Beech?
With a lot near Hartford, most viewers run in a mobile browser; screenshots help offline.

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.
