Where to see the official Pottawatomie County flood zone map
FEMA's official flood maps for Pottawatomie County are free at the FEMA Flood Map Service Center. If a tract around Emmett has no street number yet, search the nearest road and pan to it. On acreage outside Louisville, try FEMA's National Flood Hazard Layer viewer and reports the zone wherever you click near Louisville. Switch to the Pottawatomie County ArcGIS parcel map and track down the same tract around Emmett. The Pottawatomie County record gives the parcel number and legal description that an insurer or lender near Louisville may ask for.
Opening the Pottawatomie County parcel viewer
Pottawatomie County publishes its parcels on the Pottawatomie County ArcGIS parcel map, which runs on an Esri ArcGIS web map, free to use for a lot in Louisville or a tract around Manhattan. Click any Pottawatomie County parcel near Louisville to open its record: owner, parcel ID and assessed acreage are generally listed. Bookmark our Pottawatomie County page too; it tracks the official Kansas link if it moves and lists the maps around Louisville.
Reading the zones on a Pottawatomie County flood map
For a lot in Louisville, the label matters more than the color: A and V zones are Special Flood Hazard Areas, land with a 1-percent chance of flooding in any given year (the base or 100-year flood). A surveyor working near Louisville uses the base flood elevation printed for AE zones; unnumbered A zones don't have one. If a Pottawatomie County parcel shows shaded Zone X, it falls between the base flood and the 500-year flood. Clear, unshaded X near Louisville is outside the 500-year floodplain.
The lay of the land around Westmoreland
From Westmoreland, the seat of the county, the map spreads out to Belvue, Emmett, Havensville, and Louisville.

Pottawatomie County had an estimated 26,382 people in 2023 (Census Bureau), spread across about 841 square miles. Beyond the town lots in Havensville, expect big rural parcels across the county. Pottawatomie County was organized in 1857, so deeds for older farms near Olsburg can run back a long way.

Pottawatomie County land records

Insurance, permits and map changes
Insurance is the practical stake for a Pottawatomie County buyer. When a county home sits in a Special Flood Hazard Area and is financed by a regulated or federally insured lender, flood insurance is mandatory; that applies where the local government around Emmett is in the National Flood Insurance Program. In Zone X near Louisville, insurance is a choice, not a mandate, although some lenders require it anyway. If a building near Emmett sits above the flood line, FEMA's LOMA process allows a review, generally backed by an elevation certificate from a surveyor who works in the county. New construction in a Pottawatomie County Special Flood Hazard Area generally needs a floodplain permit; the Pottawatomie County floodplain administrator can say what applies.
Pottawatomie County, KS: common questions
What does BFE mean on the flood map for Westmoreland?
Near Belvue, it is the projected water surface in the base flood; elevation certificates in Pottawatomie County are measured against it.
Is my Westmoreland address in a flood zone?
Search the Westmoreland address on FEMA's Flood Map Service Center; the effective panel shows the zone, and the county parcel map confirms the tract.
Does a 100-year floodplain near Belvue flood only once a century?
No, ground around Westmoreland mapped that way faces a 1-percent annual chance, not a once-a-century schedule.
Where do I get an elevation certificate in Pottawatomie County?
A licensed surveyor or engineer prepares it, and the building office serving Westmoreland may already have one on file for newer construction.
Is there a floodplain layer in the Pottawatomie County ArcGIS parcel map?
Check the layer list in the Pottawatomie County ArcGIS parcel map; if Pottawatomie County includes a floodplain layer, confirm the zone on FEMA's map anyway.
