Before an offer near Mound City, check the Campbell County flood zone map: a mapped flood zone changes insurance, building rules and resale. This Campbell County guide covers: finding the address on FEMA's map, reading the zone codes, and pairing it with the District III regional GIS map.
Getting started with the Campbell County flood zone map
For parcel-by-parcel detail, try the National Flood Hazard Layer viewer, which lets you click a spot and read its zone, whether the land is near Missouri River or elsewhere in the county. Vacant ground around Mound City is still easy to locate: pan from the closest town and click inside the land.
Getting to the right map
Lots and tracts near Vanderbilt Archeological Site are published on the District III regional GIS map, which opens without registering. When a rural tract has no street number, pan along the nearest road and click the parcel itself, and that holds around Vanderbilt Archeological Site too. If the land is near Artas, a pop-up or side panel normally shows the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Backing up the map with records
Before you sign anything, request the recorded deed through the Register of Deeds; the parcel map near Artas only summarizes it. For a parcel near Vanderbilt Archeological Site, use the document number from the tax record so staff can find the deed fast.

A quick look at the area
Mound City is the county seat, which is where the courthouse records live. You'll also find Herreid, Artas, Pollock, and Vanderbilt Archeological Site, where town lots give way to larger tracts. About 1,340 people live in Campbell County (Census estimate, 2023) across some 734 square miles. Places such as Missouri River help you orient on the aerial.
Use the county map alongside FEMA
FEMA's map shows zones but not ownership, so pair it with the District III regional GIS map to see exactly which lot near Vanderbilt Archeological Site you're looking at.
What to request from a seller
For a tract near Herreid, ask the seller for any Elevation Certificate before closing; getting a quote early avoids surprises.
Low spots and local drainage
Creeks and ditches near Pollock may not have detailed mapping, so walk the land after rain. Marshy spots near Vanderbilt Archeological Site can limit building too; check the National Wetlands Inventory mapper for a first look.
What the map can't tell you
If the land is near Mound City, the acreage figure is a tax-roll number; only a licensed surveyor sets the real boundary on the ground. Closer to Vanderbilt Archeological Site, owner names and values update on a schedule, so a deed recorded last month can take weeks to appear.
What a flood zone means for a buyer
If a building sits in a Special Flood Hazard Area and the loan is federally backed or regulated, mandatory purchase rules apply where the community participates in the National Flood Insurance Program, and that holds around Mound City too. Remodeling a house in a zone near Mound City often needs a floodplain permit; call the permitting office early.

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.
