Ahead of any purchase around Huxley, pull up the Story County flood zone map: FEMA's zone label affects insurance, permits and resale. Covered here for Story County: locating a parcel on FEMA's map, decoding A, AE and X, and confirming the outline on the county map.
Getting started with the Story County flood zone map
For a home near Cambridge, the official source is FEMA's Flood Map Service Center: enter the street address, then open the map view for that panel. Rural land near Colo with no street number can still be found: zoom in from US Route 69 and click inside the land.
Getting to the right map
Parcels around Fernald are published on the Story County Beacon site, a viewer that needs no account. If you only know roughly where the land is, pan along US Route 69 and select the outline, which applies near Colo as much as anywhere. For acreage around Cambridge, copy the parcel ID while you have it open; each office in the county asks for it first.
Zones on the Story County flood zone map
For a home near Cambridge, A and V zones mark the Special Flood Hazard Area, which FEMA defines as a 1% annual chance of flooding. In and around Cambridge, minimal risk is not no risk: FEMA notes that floods happen outside mapped zones too.
Low spots and local drainage
Creeks and ditches near Nevada aren't always studied in detail, so walk the land after rain. Wetlands near Nevada can limit building even outside a flood zone; check the National Wetlands Inventory mapper for a first look.
What to request from a seller
For land near Collins, ask the listing agent for any Elevation Certificate before closing; getting a quote early keeps the budget honest.
Which office to call
Questions about value or the owner field for land near Colo go to the County Assessor, since that office keeps the assessment data. Zoning, permits and septic questions near Huxley need the planning or permitting office, town or county, depending on location.
Lining it up with the parcel map
FEMA doesn't draw property lines, so pair it with the Story County Beacon site to see exactly which lot near Cambridge you're looking at.
Reading the legal description
Iowa is laid out under the Public Land Survey System, so deeds around Ames reference sections and townships. Each section is nominally a mile square, about 640 acres, with 36 sections to a township, though corrections make some sections near Fernald odd-sized. Write down the legal description for the tract near Huxley for any title or survey request.
Where the recorded documents are
Before you sign anything, request the recorded deed from the County Recorder; the parcel line is a drawing of it, for land near Fernald included. Closer to Cambridge, bring the instrument number from the tax record so staff can find the deed fast.
On site with the map
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Colo, but coverage can be spotty out of town. A printout of the tract near Colo keeps working without signal.
What the map can't tell you
For a parcel near Ontario, listed acreage is an estimate; only a licensed surveyor can set the real corners on the ground. If the land is near Gilbert, records update in batches, so a deed recorded last month may not show yet.
When a parcel crosses a boundary
The county touches Boone County, Hamilton County, Hardin County, Jasper County, and Marshall County; every one of them runs a separate parcel map, at least around Huxley. Ground near Cambridge that runs to the line can show up across two assessors' files, so look at the adjacent map too. On ground around Iowa Center, the Platbookmapper state page lists each neighboring county map for Iowa.
What a flood zone means for a buyer
In and around Colo, get the Elevation Certificate if one exists: it can change the insurance price a lot. Remodeling a house in a zone near Gilbert usually means extra permit review; call the permitting office before you plan.
Getting your bearings
Nevada holds the county offices, which is where the courthouse records live. Other places on the map include Ames, Cambridge, Collins, and Colo. Roughly 98,566 people call Story County home (Census estimate, 2023) on some 573 square miles. The county was formed in 1846, and some chains of title near Huxley are long.
Story County: common questions
How often are flood maps updated in Story County?
Short answer: zones near Cambridge can shift when FEMA updates a panel; check the effective date on the panel.
Is AE a high-risk flood zone near Fernald?
For acreage around Ames, an AE zone has a 1% annual chance of flooding and a base flood elevation; unnumbered A zones don't list one.
Why does the BFE matter near Collins?
If the land is near Ames, the BFE is printed in AE zones on FEMA's map; local rules may require building above it.
How do I check the flood zone for an address near Cambridge?
It depends, but look up the spot near Colo in FEMA's National Flood Hazard Layer viewer; no account is needed.
Is there a way to export the map for land near Huxley?
For acreage around Ontario, some viewers offer PDF export; downloads of raw data vary by county.
