Before you buy or build near Maitland, check the Holt County flood zone map: the zone on that map shapes insurance, permits and resale. Covered here for this county: finding the address on FEMA's map, reading the zone codes, and pairing it with the IntegrityGIS - Holt County, at least around Kings Grove.
Checking the Holt County flood zone map step by step
If you'd rather pan and zoom, open the National Flood Hazard Layer viewer, where zone shading sits over a photo base, for land near Kings Grove included. Rural land near Bigelow with no street number is still easy to locate: search the nearest road and click inside the land.
Getting to the right map
Begin with the IntegrityGIS - Holt County; it covers every tax parcel around Curzon and Craig. For a tract near Bigelow, enter a street address, an owner's name or a parcel number, and the viewer zooms to the match. For property near Oregon, save the parcel ID while you have it open; each records desk in the county will want it.
Decoding the flood zone labels
For land near Maitland, any A or V zone mark the Special Flood Hazard Area, land with a 1-percent chance of flooding in any year. If the land is near Craig, shaded Zone X marks moderate flood hazard, roughly the 100- to 500-year range; plain X, or C on older maps, is minimal risk.
Neighboring parcel maps
The county borders Doniphan County, KS, Andrew County, Atchison County, Nodaway County, and Nemaha County, NE, and each of those keeps its own parcel map for land near Corning. Ground near Maitland that runs to the line can show up across two assessors' files, so check the neighboring map before you assume the acreage. For property near Forbes, our state page lists every bordering county map across Missouri.
Offices that can help
Deeds, mortgages and recorded plats for land near Oregon come from the Recorder of Deeds, sometimes only in person. Zoning, permits and septic questions near Craig are for the local planning and health departments, town or county, depending on location.
Water near Forest City
Small streams around Curzon may not have detailed mapping, so walk the land after rain. Wet ground around New Point is a separate issue from flood zones; the National Wetlands Inventory mapper shows mapped wetlands.
Getting your bearings
Oregon serves as the county seat, where most land records are kept. You'll also find Craig, Forest City, Maitland, and Mound City, where town lots give way to larger tracts. Around 4,248 people call Holt County home (Census estimate, 2023) on about 463 square miles. The county dates to 1841, so old deeds can run back a long way for land near Forest City.
Parcel lines plus flood zones
FEMA doesn't draw property lines, so check the IntegrityGIS - Holt County too for the outline of the tract near Craig.
Legal descriptions in Missouri
Missouri uses the Public Land Survey System, so deeds around Corning reference sections and townships. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though real sections near Big Lake vary in size. Keep the legal description for land near Bigelow before you request a deed or survey.
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, the lender will require flood insurance where the community participates in the National Flood Insurance Program, and that holds around Kings Grove too. Building or adding on near Maitland in a mapped zone usually means extra permit review; call the permitting office early.
Backing up the map with records
The map is an index, not the title: deeds, subdivision plats and easements for land near Craig are kept by the Recorder of Deeds. For acreage around Forbes, have ready the instrument number from the tax record to skip a name search.
Questions to ask before you buy
On ground around Bigelow, request about past flood claims before closing; getting a quote early keeps the budget honest.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Mound City, though signal can drop in rural spots. A screenshot of the parcel near Big Lake with its ID keeps working without signal.
Questions about the Holt County flood zone map
When is flood insurance required near Oregon?
It depends, but for a building near Oregon in an A or V zone with a federally backed or regulated mortgage, it's generally required; elsewhere it's optional.
What is a LOMA around Kings Grove?
Short answer: FEMA's LOMA process is the usual route when a building near Maitland sits above the base flood elevation; a surveyor's elevation data supports it.
Can I see flood zones on the IntegrityGIS - Holt County?
It depends, but a flood layer may appear in the IntegrityGIS - Holt County layer list, but FEMA's own map is the official source.
Is my property near Curzon in a flood zone?
It depends, but FEMA's free map shows the zone for any spot near Kings Grove, which takes a couple of minutes.
Does the parcel map work on a phone near Corning?
Near Mound City, no app is needed for most county viewers; screenshots help offline.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
