Buying Land in Pierce County, Wisconsin

Pierce County, seat Ellsworth, sits in Wisconsin's far western corner at the confluence of the St. Croix and Mississippi Rivers -- close enough to the Twin Cities to be part of its official metro area, and shaped by dairy farmland under real conversion pressure. Zoning here follows the standard county pattern almost everywhere except the Town of River Falls, and the county's stretch of the St. Croix River carries its own distinct federal-scenic-riverway zoning layer on top of the state's usual shoreland rules.

County Zoning Covers 16 of 17 Towns -- River Falls Opted Out in 1998

Case-by-case / verify locally

Pierce County's Land Management Department administers general zoning across the county's unincorporated towns, and this covers essentially all of them -- Clifton, Diamond Bluff, Ellsworth, El Paso, Gilman, Hartland, Isabelle, Maiden Rock, Martell, Oak Grove, Rock Elm, Salem, Spring Lake, Trenton, Trimbelle, and Union all use Pierce County zoning. The one confirmed exception is the Town of River Falls, which adopted the county's 1972 comprehensive zoning ordinance but formally withdrew from it in 1998 and has administered its own separate town zoning code ever since. If your target parcel is in or near the Town of River Falls, confirm directly with the town rather than assuming county zoning maps or districts apply.

The Lower St. Croix Riverway Adds NR 118 Rules Along the River

Case-by-case / verify locally

Pierce County's entire St. Croix River frontage (down to the Mississippi confluence at Prescott) sits within the Riverway's Lower segment, which is regulated through Wisconsin Administrative Code NR 118 -- a local-zoning-based standard with a much larger structure setback (200 feet from the bluffline in the conservation management zone, versus the standard statewide NR 115 baseline of 75 feet) than most Wisconsin shoreland. See our dedicated zoning page for how this differs from the federally-owned/easement-based Upper segment covered on this project's Burnett County page.

A Twin Cities Exurb With Real Farmland-Conversion Pressure

Case-by-case / verify locally

Pierce County is one of only two Wisconsin counties (with St. Croix County) formally included in the Minneapolis-St. Paul-Bloomington, MN-WI Metropolitan Statistical Area, and it's roughly an hour's drive from the Twin Cities. Over three-quarters of the county's land is assessed for agricultural use, but the county's own farmland preservation planning documents describe a clear trend toward fewer dairy farms, a split toward more small and very large farms, and continued conversion of agricultural land to residential use -- worth factoring in if you're evaluating land for its long-term rural character versus its subdivision potential.

Zoning: county-administered almost everywhere, except the Town of River Falls

Pierce County Land Management (414 W. Main St., Ellsworth, WI 54011; (715) 273-6746 / (715) 273-6747) administers the county's general zoning, along with the county's floodplain, shoreland, wetland, subdivision, and St. Croix Riverway ordinances, and serves as the County Land Information (GIS) Office. This covers essentially all 17 of the county's towns under a single zoning-map and district system, which is a comparatively clean pattern relative to some other Wisconsin counties in this project.

The one confirmed exception is the Town of River Falls, in the county's northeast corner near the City of River Falls (itself straddling Pierce and St. Croix Counties, and home to UW-River Falls). The Town of River Falls adopted the county's revised 1972 comprehensive zoning ordinance, but its own published comprehensive-plan documents state that the town formally withdrew from county zoning in 1998 and has administered its own zoning code independently since. If a target parcel sits in that town, confirm zoning, permitted uses, and setbacks directly with the Town of River Falls rather than the county -- and don't confuse the town with the separately-incorporated City of River Falls, which runs its own municipal zoning as well.

The Lower St. Croix Riverway: a distinct federal-standard overlay along the river

Pierce County's entire stretch of the St. Croix River -- from the county line down to the river's confluence with the Mississippi at Prescott -- falls within the St. Croix National Scenic Riverway's Lower segment, the portion of the Riverway that Wisconsin and Minnesota manage primarily through local zoning ordinances built to Wisconsin Administrative Code NR 118's minimum standards, rather than through direct federal land ownership. Pierce County Land Management explicitly lists 'St. Croix Riverway' among the ordinances it administers, alongside floodplain, shoreland, wetland, and subdivision review.

This is a meaningfully different regulatory model from the Riverway's Upper segment (covered by this project's Burnett County page), where the National Park Service controls land directly through fee ownership and recorded scenic easements. See our dedicated zoning page for the practical difference this makes -- including NR 118's larger structure setbacks in the conservation management zone (200 feet from the bluffline, well beyond the standard statewide NR 115 baseline of 75 feet) -- before assuming standard shoreland-zoning rules are the only overlay on a St. Croix-adjacent Pierce County parcel.

A Twin Cities exurb built on dairy farmland, under real conversion pressure

Pierce County is one of only two Wisconsin counties -- alongside neighboring St. Croix County -- formally included in the Minneapolis-St. Paul-Bloomington, MN-WI Metropolitan Statistical Area, reflecting how many county residents commute to the Twin Cities, roughly an hour away. Agricultural land dominates the landscape (over three-quarters of the county's land is assessed for agricultural use), and the county participates in Wisconsin's Working Lands farmland preservation program, which lets qualifying landowners claim an annual state income-tax credit in exchange for meeting soil-and-water conservation standards.

At the same time, the county's own planning documents describe a clear trend: fewer dairy farms, a growing split between small hobby-scale parcels and very large operations, and continued conversion of farmland to residential use as Twin Cities-driven demand pushes west. If you're evaluating agricultural or semi-rural land here, factor in both directions -- Farmland Preservation Program enrollment (with its tax benefit and its land-use commitment) on one hand, and genuine, ongoing residential-conversion pressure on the other.

The Kinnickinnic River: a live dam-removal project worth knowing about

The Kinnickinnic River (the 'Kinni'), a Class I trout stream that flows through the City of River Falls before joining the St. Croix, currently has two dams -- Powell Dam and Junction Falls Dam -- that create the Lake George and Lake Louise impoundments in town. In April 2026, the U.S. Army Corps of Engineers, St. Paul District approved a feasibility report and Finding of No Significant Impact recommending both dams be removed to restore roughly 1.5 miles of natural river channel, lower water temperatures, and improve trout habitat; the project was moving into design and implementation as of this research pass, not yet completed. If you're evaluating land along the Kinni corridor in or near River Falls, this is worth tracking directly with the City of River Falls and the project's sponsors, since a dam-removal project of this scale can change adjacent water levels, flood mapping, and shoreline character over time.

Ellsworth itself is known statewide as the 'Cheese Curd Capital of Wisconsin,' home to the Ellsworth Cooperative Creamery -- a dairy cooperative with roots to 1903 that sources milk from patron farm families across Wisconsin and Minnesota and produces roughly 180,000 pounds of cheese curds a day. It's a useful marker of just how central dairy farming remains to the county's identity and economy, even amid the residential-conversion pressure described above.

Septic, GIS, records, and other departments to know

POWTS (septic) sanitary permits and site evaluations run through Pierce County Land Management under the statewide SPS 383 standard, the same office that handles zoning and shoreland review. The Register of Deeds ((715) 273-6748) holds recorded deeds, easements, and plats; the Treasurer ((715) 273-6743) handles property tax payment; and the Land Conservation Department ((715) 273-6763) works on soil, water, and conservation programs separate from zoning administration.

UW-Madison Division of Extension's Pierce County office (Courthouse Annex, 432 West Main, Ellsworth, WI 54011; (715) 273-6781) supports the county's agricultural sector, and the County Highway Department ((715) 273-5096) handles county road and access questions.

What we could and couldn't confirm

Direct WebFetch access to co.pierce.wi.us and cms5.revize.com (the county's document host) was blocked by a network egress restriction throughout this research pass, so this page relies on search-indexed excerpts rather than a full verbatim read of the current zoning ordinance text or a complete, current town-by-town confirmation. The Town of River Falls' 1998 withdrawal from county zoning is drawn from the town's own published comprehensive-plan document, treated as a reliable primary source, but this research pass found no equivalent documented exception for any other Pierce County town -- the absence of a found record is not the same as a confirmed, current, town-by-town status check, so confirm directly for any specific parcel. The Minneapolis-St. Paul-Bloomington MSA membership claim (Pierce and St. Croix Counties only, among Wisconsin counties) and the farmland-conversion trend are drawn from regional economic-development and the county's own farmland-preservation planning sources. The Kinnickinnic River dam-removal project was in the design/implementation phase, not completed, as of this research pass (April 2026 USACE approval) -- its ultimate effect on adjacent water levels and shoreline is not yet known and should not be assumed either way for a specific parcel.

Verify directly with: Pierce County Land Management ((715) 273-6746) for zoning, septic, and shoreland/Riverway questions on any parcel outside the Town of River Falls, the Town of River Falls directly for parcels within it, and the City of River Falls or the Kinnickinnic dam-removal project sponsors for the current status of that restoration project
