Before an offer near Spring Hill, look at the Norwalk flood zone map: the zone on that map shapes insurance, building rules and resale. This Norwalk guide covers: locating a parcel on FEMA's map, decoding A, AE and X, and pairing it with the Warren County Beacon site.
Where the Norwalk flood zone map lives
The official source is FEMA's Flood Map Service Center: type an address near Martensdale, and choose the dynamic map. A tract near Cumming without an address can still be found: pan from the closest town then click the parcel area.
Opening the official parcel viewer
Go first to the Warren County Beacon site; it covers each assessed parcel in the county, Martensdale included. For property near Martensdale, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For acreage around Spring Hill, the parcel card typically gives the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
A word on accuracy
Listed acreage is a tax-roll number; just a licensed surveyor sets the real boundary for a parcel near Cumming. Closer to Martensdale, records update in batches, so a deed recorded last month can take weeks to appear.
What to request from a seller
Ask the listing agent whether the home has flooded on the property near Cumming; an insurance quote early avoids surprises.
Norwalk, IA: the basics
Norwalk lies within Warren County, Iowa, which means parcel data comes from the county. For a home near Cumming, 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 city limits out by Martensdale usually answers to county rules instead.
What the zone letters mean
For a home near Cumming, zones beginning with A or V mark the Special Flood Hazard Area, meaning a 1% or greater chance of flooding each year. Out toward Martensdale, minimal risk is not no risk: according to FEMA, many claims come from moderate- and low-risk areas.
Matching the zone to the lot lines
FEMA's map shows zones but not ownership, so check the Warren County Beacon site too to confirm you have the right parcel near West Des Moines.
What a flood zone means for a buyer
If a building sits in a Special Flood Hazard Area and a federally regulated lender is involved, flood insurance is generally required in communities in the NFIP, whether the land is near Bevington or elsewhere in the county. Building or adding on near Des Moines in a mapped zone can trigger elevation rules; ask the local floodplain administrator early.
Deeds, plats and who keeps them
Before you sign anything, get the recorded deed from the County Recorder; the parcel map near Spring Hill only summarizes it. For land near Bevington, have ready the book and page shown in the record panel so staff can find the deed fast.
Warren County in a few facts

Around 55,205 people call Warren County home (Census Bureau estimate, 2023) spread over some 570 square miles. Warren County was formed in 1846, and some chains of title near Spring Hill are long.
Water near Bevington
Low-lying fields near Martensdale aren't always studied in detail, so ask neighbors about past flooding. Wet ground around Bevington is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Land on the county line
Warren County borders Clarke County, Dallas County, Lucas County, Madison County, and Marion County; every one of them runs a separate parcel map. Acreage along the edge near Des Moines may show up in two county records, so check the adjacent map too. For a parcel near Martensdale, our state page lists each bordering county map for Iowa.
Sections, lots and bearings
Iowa is laid out under the Public Land Survey System, so rural legal descriptions near Martensdale cite section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Spring Hill can be irregular. Write down the legal description for the tract near Cumming when you talk to a surveyor.
Norwalk: common questions
What is a base flood elevation around Cumming?
Usually, a BFE near Cumming tells builders how high the lowest floor should be, and an Elevation Certificate compares the building to it.

What is a LOMA in Norwalk?
Short answer: FEMA's LOMA process is the usual route when a building near Cumming sits above the base flood elevation, and lenders accept the result.
Do I need to worry about flooding in Zone X for land near Cumming?
