Before you buy or build near Cushing, look at the Woodbury County flood zone map: the zone on that map shapes insurance, permits and resale. What this county guide covers: finding the address on FEMA's map, decoding A, AE and X, and pairing it with the county Beacon site, at least around Sioux City.
Getting started with the Woodbury County flood zone map
For a parcel near Discord, flood zones come from FEMA's Flood Map Service Center: enter the street address, and choose the dynamic map. Rural land near Correctionville with no street number is still easy to locate: search the nearest road and click the spot.
The viewer Woodbury County publishes
Your first stop is the Woodbury County Beacon site; it includes every tax parcel in the county, Bronson included. When a rural tract has no street number, pan along the nearest road and click the parcel itself, whether the land is near Cushing or elsewhere in the county. For a home near Anthon, copy the parcel ID before closing the panel; every records desk in the county uses it to find the file.
Beyond the mapped zones
Low-lying fields near Dodds may not have detailed mapping, so look for water marks and debris lines. Wet ground around Cushing is a separate issue from flood zones; check the National Wetlands Inventory mapper for a first look.
Places you'll see on the map
Sioux City holds the county offices, which is where the courthouse records live. You'll also find Anthon, Bronson, Correctionville, and Cushing, where town lots give way to larger tracts. Around 105,951 people live in the county (Census Bureau estimate, 2023) across roughly 873 square miles, especially near Danbury.
What the zone letters mean
Zone AE carries a published BFE, while plain Zone A does not; builders around Dodds design to it. Out toward Discord, a low-risk label isn't a guarantee: according to FEMA, many claims come from moderate- and low-risk areas.
Reading the legal description
Iowa is laid out under the Public Land Survey System, which means a tract near Hornick 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 sections near Climbing Hill can be irregular. Copy the legal description from the record for the parcel near Discord before you request a deed or survey.
Which office to call
Questions about value or the owner field for land near Grange belong with the County Assessor, which maintains the tax roll. Building or septic questions for a lot near Discord are for the local planning and health departments, and the answer depends on jurisdiction.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so pair it with the Woodbury County Beacon site to confirm you have the right parcel near Climbing Hill.
What to request from a seller
Closer to German City, request about past flood claims before closing; an insurance quote early keeps the budget honest.
Next door to the county, especially near Anthon.
Woodbury County touches Cherokee County, Crawford County, Ida County, Monona County, and Plymouth County, all with their own assessor records. A tract near the line by Hornick can show up across two assessors' files, so open the adjacent map as well. Near Danbury, our state page links every bordering county map for Iowa.
Insurance, lenders and building
Closer to Grange, get the Elevation Certificate if one exists: it compares the building to the BFE. Building or adding on near Dodds in a mapped zone often needs a floodplain permit; call the permitting office early.
Limits of the parcel data
For property near Discord, the acreage figure is an estimate; only a licensed surveyor can set the real boundary on the ground. Near Correctionville, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Taking the map into the field
Most viewers work in a phone browser, handy when you're parked on a road near Discord, though signal can drop in rural spots. A saved image of the lot near Bronson and its lines is a good backup.
Backing up the map with records
Before you sign anything, request the recorded deed through the County Recorder; the viewer just points to it, for land near Climbing Hill included. Out toward Hornick, bring the document number shown in the record panel to skip a name search.
Quick answers
Is flood insurance mandatory near Bronson?
For a parcel near Dodds, it's typically required only for structures in high-risk zones with federally backed loans, in communities that take part in the NFIP.
Is AE a high-risk flood zone in Woodbury County?
Usually, both are high-risk zones, but only AE has a base flood elevation, which shapes building rules near Sioux City.
Is Zone X safe from flooding near Hornick?
Closer to Sioux City, shaded X is moderate risk and unshaded X is minimal risk, and floods still happen outside high-risk zones.
Does the county parcel map show flood zones near Anthon?
Generally, a flood layer may appear in the Woodbury County Beacon site layer list, though it can lag behind FEMA's current panels.
Why do offices ask for the parcel ID for land near Cushing?
Every office uses it to pull the same file for land near Hornick; you'll see it in the viewer and on tax statements.
