Before you buy or build near Olsburg, look at the Manhattan flood zone map: a mapped flood zone changes insurance, permits and resale. Covered here for Manhattan: locating a parcel on FEMA's map, reading the zone codes, and matching it with the county parcel viewer.
The Manhattan flood zone map: start here
Flood zones come from FEMA's Flood Map Service Center: type an address near Louisville, and pick the FIRMette or map view. A tract near Belvue without an address can still be found: search the nearest road and click inside the land.
Getting to the right map
Begin with the Pottawatomie County ArcGIS parcel map; it covers every tax parcel from Westmoreland to St. George. For a parcel near Wamego, enter a street address, an owner's name or a parcel number, then pick the result to center the map on it. For land near Belvue, the parcel card usually lists the owner of record, assessed acreage, a parcel ID and sometimes recent sales.
Where Manhattan fits in
Manhattan is part of Pottawatomie County, Kansas, and the county assessor maps its lots. For a home near Westmoreland, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Land beyond the city limits toward Olsburg usually follows county rules rather than the town's.
Low spots and local drainage
Small streams around Belvue aren't always studied in detail, so look for water marks and debris lines. Wetlands near Olsburg can limit building even outside a flood zone; the National Wetlands Inventory mapper shows mapped wetlands.
When a parcel crosses a boundary
Pottawatomie County touches Jackson County, Marshall County, Nemaha County, Riley County, and Shawnee County; every one of them runs a separate parcel map. A tract near the line by Wamego can show up across two assessors' files, so open the neighboring map too. Around Wamego, our state page links every neighboring county map across Kansas.
Zones on the Manhattan flood zone map
Zone AE comes with a base flood elevation, which plain A zones lack; surveyors near Olsburg use that number. For a home near Wamego, a low-risk label isn't a guarantee: FEMA notes that floods happen outside mapped zones too.
Lining it up with the parcel map
FEMA's map shows zones but not ownership, so check the Pottawatomie County ArcGIS parcel map too for the outline of the tract near St. George.
Places you'll see on the map
Westmoreland serves as the county seat, home to the main records offices. Other places on the map include St. George, Wamego, Louisville, and Olsburg, where town lots give way to larger tracts. Roughly 26,382 people call Pottawatomie County home (Census estimate, 2023) across about 841 square miles. Pottawatomie County dates to 1857, and some chains of title near Belvue are long.
Field tips
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Wamego, but coverage can be spotty out of town. A screenshot of the parcel near St. George with its ID keeps working without signal.
Money questions tied to the zone
Around St. George, ask for an Elevation Certificate: it compares the building to the BFE. New construction in a floodplain near St. George can trigger elevation rules; check with the county or town building office early.
Getting answers from the right desk
Questions about value or the owner field for land near Olsburg belong with the County Appraiser, since that office keeps the assessment data. Questions about what you can build around Olsburg need the planning or permitting office, depending on whether the land is inside town limits.
A word on accuracy
Acreage on the record is a tax-roll number; only a licensed surveyor sets the real corners on land around Louisville. For acreage around Westmoreland, records update in batches, so a deed recorded last month might lag behind.
Recorded documents worth pulling
The map is an index, not the title: recorded deeds, plats and easements covering ground around Westmoreland are kept by the Register of Deeds. Long-held tracts near Belvue can go back through many deeds, and a title company earns its fee if money is changing hands.
A short flood checklist
Ask the seller whether the home has flooded on the property near Belvue; getting a quote early keeps the budget honest.

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.
