Buying Land in Pottawatomie County, Kansas

Pottawatomie County, seat Westmoreland, is a genuine growth story: Census data show it had the largest percentage population growth of any Kansas county from 2010 to 2020, driven by its shared border with Manhattan and its position on the corridor toward the Kansas City metro. The county runs real, active zoning through a Planning & Zoning Office and Unified Development Regulations -- though a live September 2026 case shows the county commission can, and does, override its own Planning Commission's rezoning recommendations. The county sits outside every one of Kansas's five Groundwater Management Districts.

Kansas's Fastest-Growing County, 2010-2020, and Still Climbing

Could not confirm

U.S. Census data show Pottawatomie County grew 17.3% between the 2010 and 2020 censuses (from 21,604 to 25,348 residents) -- the largest percentage population gain of any Kansas county over that decade. The county's own demographic estimate puts 2025 population at roughly 27,186, indicating the growth has continued rather than plateaued. Much of this pressure ties to Manhattan, which is the seat of neighboring Riley County but physically extends into Pottawatomie County, and to the county's position along the broader corridor linking the Manhattan area toward the Kansas City metro. For a land buyer, this means real and rising demand for rural acreage, subdivision, and rezoning activity in the county's Manhattan-adjacent townships -- a genuinely different dynamic than a static or declining rural county.

Real, Active Zoning -- But the County Commission Can Override Planning Staff

Case-by-case / verify locally

Pottawatomie County runs an actively administered zoning program through its Planning & Zoning Office (207 N. 1st St., Westmoreland; 785-457-3551), which implements the county's Unified Development Regulations and Comprehensive Plan. A county Planning Commission reviews rezoning and conditional-use requests and also serves as the county's Board of Zoning Appeals. This is a real, functioning system -- but it is not purely technical or automatic: in early September 2026, the Board of County Commissioners voted to override the Planning Commission's own recommendation and approved a rezoning from A1 (agricultural) to AB (ag-business) for a property on McDonald Road near Havensville. That's a useful, current reminder that final zoning decisions in Pottawatomie County rest with elected commissioners, not planning staff -- a neighboring parcel's zoning designation can shift by commission vote even against a planning recommendation.

Outside Every Kansas Groundwater Management District

Generally favorable

Pottawatomie County sits in northeast Kansas, outside the boundaries of all five of the state's Groundwater Management Districts, which cover only western and south-central Kansas over the Ogallala, Equus Beds, and Big Bend aquifer systems. Water rights for a Pottawatomie County parcel are administered directly by the Kansas Division of Water Resources under the state's standard prior-appropriation framework, without an added regional layer of GMD-set well-spacing or allocation rules.

A real growth corridor, with the demand pressure to prove it

Pottawatomie County's growth is not a marketing claim -- it shows up directly in Census figures. Between the 2010 and 2020 decennial censuses, the county's population rose 17.3%, from 21,604 to 25,348 residents, the largest percentage increase of any county in Kansas over that period. County demographic estimates put the 2025 population at roughly 27,186, suggesting the trend has kept running rather than flattening out after the last census. Much of the growth concentrates near Manhattan: while Manhattan itself is the seat of Riley County, the city physically extends across the county line into Pottawatomie County, and Pottawatomie's own growth is closely tied to Manhattan-area development and to the broader corridor connecting the Manhattan region toward the Kansas City metropolitan area further east.

For a land buyer, this is a genuinely different situation than the flatter, rural counties covered elsewhere on this site: real demand exists for rural-residential acreage, small-acreage subdivisions, and agricultural-to-commercial rezonings in Pottawatomie County's Manhattan-adjacent and corridor townships. That demand cuts both ways -- it can support land values, but it also means zoning and land-use decisions in the county carry real, current stakes rather than being a rarely-touched formality.

Zoning is real and active -- and county commissioners have the final word

Pottawatomie County administers genuine, active zoning for its unincorporated area through its Planning & Zoning Office in Westmoreland, which implements the county's Unified Development Regulations (its zoning code) and Comprehensive Plan. A county Planning Commission reviews proposed rezonings, conditional-use permits, and plats, and also functions as the county's Board of Zoning Appeals for variance requests -- a combined role similar to several other Kansas counties covered on this site.

What's worth flagging directly, because it's current rather than historical, is that Planning Commission recommendations are not the final word. In early September 2026, Pottawatomie County commissioners voted to override the Planning Commission's recommendation and approved a rezoning from A1 (agricultural) to AB (ag-business) for a parcel on McDonald Road near Havensville, allowing construction of an office and equipment storage yard on land the Planning Commission itself had not recommended for that change. This is a genuine, on-the-record example of the county's elected Board of Commissioners exercising its statutory authority to approve or reject a rezoning independent of the Planning Commission's recommendation. For a buyer near a parcel with a pending or contested rezoning request -- especially in the county's faster-growing townships -- this means outcomes are not fully predictable from the Planning Commission's staff-level recommendation alone; tracking the Board of County Commissioners' own agenda and decisions matters just as much.

What we could and couldn't confirm

Pottawatomie County's Planning & Zoning Office structure and Planning Commission/Board of Zoning Appeals role are drawn from the county's own published department pages. The September 2026 McDonald Road/Havensville rezoning override is drawn from two independent local news reports (News Radio KMAN and B104.7) published the same week. Population growth figures (17.3% growth 2010-2020, the largest of any Kansas county, and the 2025 estimate of roughly 27,186) are drawn from a Manhattan Mercury report on Census data and the county's own Demographics page. The county's exclusion from all five Groundwater Management Districts was confirmed against each GMD's own published member-county list via Kansas Department of Agriculture materials -- none list Pottawatomie County.
