Before an offer near Cumming, look at the West Des Moines flood zone map: FEMA's zone label affects insurance, building rules and resale. In this West Des Moines guide: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the Warren County Beacon site.
The West Des Moines flood zone map: start here
Start with FEMA's Flood Map Service Center: search an address around Martensdale, then open the map view for that panel. A tract near Des Moines without an address is still easy to locate: zoom in from the nearest road and click inside the land.
Pulling up a parcel
Your first stop is the Warren County Beacon site; it includes every tax parcel around Cumming and Spring Hill. When a rural tract has no street number, pan along the nearest road and click the parcel itself, whether the land is near Norwalk or elsewhere in the county. Near Bevington, a pop-up or side panel normally shows the owner of record, acreage on the tax roll, the parcel number and in many cases the last transfer.
Limits of the parcel data
The acreage figure is an assessed number; just a licensed surveyor sets the real lines for a parcel near Norwalk. Near Des Moines, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Questions to ask before you buy
Request for any Elevation Certificate for the house near Martensdale; an insurance quote early avoids surprises.
West Des Moines, IA: the basics
West Des Moines sits in Warren County, Iowa, and the county assessor maps its lots. If the land is near Martensdale, the municipality handles matters such as zoning, permits and utilities for lots inside the boundary, but the county runs assessment and recording. Land beyond the town limits near Martensdale often follows county rules, not municipal ones.
When a parcel crosses a boundary
Warren County borders Clarke County, Dallas County, Lucas County, Madison County, and Marion County, all with their own assessor records. Acreage along the edge near Martensdale can be split in two county records, so look at the neighboring map too. On ground around Martensdale, our state page links each bordering county map across Iowa.
Zones on the West Des Moines flood zone map
Near Cumming, any A or V zone are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any year. For a tract near Spring Hill, a shaded X area is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, means minimal mapped risk.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Martensdale, though signal can drop in rural spots. A printout of the tract near Martensdale helps when you meet an owner or agent.
Reading the legal description
Iowa uses the Public Land Survey System, which means a tract near Des Moines is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though corrections make some sections near Cumming odd-sized. Keep the legal description for land near Martensdale when you talk to a surveyor.
Use the county map alongside FEMA
FEMA doesn't draw property lines, so check the Warren County Beacon site too to confirm you have the right parcel near Cumming.
Insurance, lenders and building
With a lot near Bevington, an Elevation Certificate from a surveyor helps: it can change the insurance price a lot. Remodeling a house in a zone near Cumming often needs a floodplain permit; call the permitting office before you plan.
Low spots and local drainage
Creeks and ditches near Martensdale may not have detailed mapping, so look for water marks and debris lines. Wet ground around Cumming is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Deeds, plats and who keeps them
The map is an index, not the title: recorded deeds, plats and easements for land near Spring Hill are kept by the County Recorder. With a lot near Bevington, use the document number from the tax record to skip a name search.
Frequently asked
Does the county parcel map show flood zones for land near Cumming?
Usually, a flood layer may appear in the Warren County Beacon site layer list, though it can lag behind FEMA's current panels.
Is AE a high-risk flood zone near Martensdale?
Usually, both are high-risk zones, but only AE has a base flood elevation, so builders near Norwalk design to that elevation.
Is flood insurance mandatory near Bevington?
Generally, lenders generally require it for buildings near Bevington in a Special Flood Hazard Area when the loan is federally regulated or insured; outside those zones it's your call.
What is a base flood elevation near Cumming?
Good question; a BFE near Spring Hill tells builders how high the lowest floor should be, and an Elevation Certificate compares the building to it.
Who do I call about a parcel near Bevington?
The County Assessor handles values and the tax roll, and the County Recorder keeps deeds; planning offices cover zoning near Norwalk
