Ahead of any purchase around Cambridge, look at the Ames flood map: the zone on that map shapes insurance, permits and resale. In this Ames guide: finding the address on FEMA's map, reading the zone codes, and pairing it with the Story County Beacon site.
Checking the Ames flood map step by step
Start with FEMA's Flood Map Service Center: search an address around Cambridge, and choose the dynamic map. A tract near Huxley without an address can still be found: zoom in from US Route 69 then click the parcel area.
The viewer Story County publishes
Begin with the Story County Beacon site; it maps each assessed parcel from Slater to Nevada. Without an address in hand, zoom in from Cambridge and click the parcel itself. On ground around Huxley, the parcel card normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Places you'll see on the map
Nevada is the county seat, which is where the courthouse records live. Other places on the map include Gilbert, Kelley, and Huxley. Roughly 98,566 people call Story County home (Census estimate, 2023) on about 573 square miles. Story County dates to 1846, and some chains of title near Gilbert are long.
Sections, lots and bearings
Iowa is laid out under the Public Land Survey System, so deeds around Gilbert reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though sections near Gilbert can be irregular. Keep the legal description for land near Huxley for any title or survey request.
Questions to ask before you buy
Request about past flood claims on the property near Kelley; an insurance quote early keeps the budget honest.
Where the recorded documents are
Before you sign anything, request the recorded deed from the County Recorder; the parcel map near Huxley only summarizes it. Long-held tracts near Slater may trace back through several deeds, and a title company can sort it out if money is changing hands.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Kelley, but coverage can be spotty out of town. A screenshot of the parcel near Kelley with its ID is a good backup.
Water near Gilbert
Low-lying fields near Huxley aren't always studied in detail, so walk the land after rain. Marshy spots near Huxley can limit building too; check the National Wetlands Inventory mapper for a first look.
Neighboring parcel maps
Story County borders Boone County, Hamilton County, Hardin County, Jasper County, and Marshall County, and each of those keeps its own parcel map. Acreage along the edge near Gilbert may show up in two county records, so open the neighboring map as well. For property near Slater, the Platbookmapper state page links each bordering county map for Iowa.
City limits and county records
Ames lies within Story County, Iowa, which means parcel data comes from the county. Local government in Ames handles things like zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Lots just outside the city limits toward Slater often answers to county rules, not municipal ones.
What the map can't tell you
Tax maps are drawn for assessment, not surveyed, so the edge of a yard near Huxley can sit a few yards off the line on screen. For land near Huxley, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Reading A, AE and X
An AE label includes a base flood elevation (BFE), while plain Zone A does not; builders around Huxley design to it. For acreage around Kelley, shaded Zone X is moderate risk, between the 1% and 0.2% annual chance floods; plain X, or C on older maps, is minimal risk.
Lining it up with the parcel map
FEMA doesn't draw property lines, so open the Story County Beacon site next to see exactly which lot near Gilbert you're looking at.
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 where the community participates in the National Flood Insurance Program, and that holds around Huxley too. Remodeling a house in a zone near Nevada can trigger elevation rules; call the permitting office before you plan.
Questions about the Ames flood map
Do I need to worry about flooding in Zone X near Kelley?
Short answer: X zones around Gilbert are lower risk, not no risk, and floods still happen outside high-risk zones.
What is a LOMA near Kelley?
You can ask FEMA for a LOMA if surveyed elevations show the building near Cambridge is above the BFE, and lenders accept the result.
What is a base flood elevation for land near Huxley?
For most people, the BFE is printed in AE zones on FEMA's map; surveyors near Slater use it often.
Is AE a high-risk flood zone in Ames?
AE is a Special Flood Hazard Area with a published base flood elevation, so builders near Kelley design to that elevation.
How is land described in Iowa deeds near Slater?
