Buying Land in Grundy County: Growth Pressure, Ag-Preservation Zoning, and the Dresden Plant

A zoning code that says, in writing, it exists to preserve farmland

It's worth taking seriously that Grundy County's Unified Development Code states its own purpose as promoting the continuation of agriculture as the predominant land use in the unincorporated county -- this isn't incidental language buried in a preamble, it's the operative policy the county's Land Use Department applies when it reviews a rezoning request. In practice, that means a request to rezone agricultural land to residential or commercial use in unincorporated Grundy County should be expected to face real scrutiny, particularly for parcels not adjacent to an existing municipality or subdivision, rather than being treated as a routine administrative approval.

For a buyer, that cuts in your favor if you're purchasing farmland specifically to keep farming it or to hold as agricultural land: the county's own stated policy supports the durability of that use and, by extension, some insulation from unwanted adjacent rezoning. It cuts the other way if you're speculating on future residential or commercial conversion of a specific parcel -- don't assume rezoning approval will be easy just because nearby land in another township has already converted.

Real subdivision growth at the edges, inside a county built around farmland preservation

Grundy County sits roughly an hour southwest of downtown Chicago, inside the metro area's broader footprint, and that proximity has produced genuine subdivision development amid the county's corn and soybean fields -- not a hypothetical risk, but a documented pattern. Wauponsee Township alone contains several named subdivisions carved out of what was previously farmland: the Bradley Subdivision, Claypool Woods, Gaslight Village, and the Lori-Sue Subdivision. Morris, the county seat, is the focal point of this growth, with a population of 14,163 at the 2020 census within a county total of 52,533.

The practical takeaway: a parcel's current zoning and its neighborhood's current land-use character are not necessarily a reliable guide to what a nearby parcel looked like ten years ago, or what a similarly situated parcel might look like ten years from now, especially near Morris or an existing subdivision boundary. Before buying, ask the Land Use Department directly about (a) any pending rezoning applications within a mile or two of your target parcel, (b) whether the parcel is within any municipality's annexation-planning area, and (c) the parcel's own zoning history. A parcel deep in a township with no adjacent development pressure is a different proposition than one abutting an existing subdivision or a municipal boundary, even if both are currently zoned Agricultural.

The Dresden Generating Station: a tax anchor today, an open question over the long horizon

Dresden Generating Station -- a 953-acre nuclear plant site near Morris, at the head of the Illinois River where the Des Plaines and Kankakee Rivers meet -- is the first privately financed nuclear power plant built in the United States, with two operating General Electric boiling-water reactors (Dresden 2 & 3, online since 1970) each producing roughly 867 megawatts for the Chicago and northern Illinois grid. It's also one of the largest single taxpayers in the county: reporting puts its annual property-tax contribution at roughly $25-26.5 million, and it directly employs 700-plus people with an annual payroll of roughly $74 million, most of whom live in Grundy and neighboring Will Counties.

For land near the plant, that scale matters in two directions. In the near term, Dresden's tax contribution is a real, current benefit that helps fund county and school-district services -- a factor worth weighing alongside property tax rates when comparing Grundy County land to a similarly priced parcel elsewhere. Over a longer horizon, though, the plant's eventual retirement is a live enough question that the Grundy County Board itself took it up: a 2020 resolution in support of nuclear power explicitly raised the prospect of a phased-in property-tax step-down and the creation of a community advisory panel to plan decommissioning and "future use" of the plant's acreage, should it eventually close. Dresden's operating reactors have no publicly announced retirement date as of this writing, so this is a long-horizon consideration rather than an imminent one -- but a buyer evaluating land in the plant's immediate vicinity, or a buyer relying heavily on the county's current tax base and services level, should be aware the county itself has flagged this as a real planning question.

Separately, Grundy County's own Emergency Management department maintains a dedicated nuclear-preparedness page, reflecting its role in the offsite emergency planning that surrounds any operating US nuclear plant -- generally structured around a roughly 10-mile plume-exposure planning zone and a roughly 50-mile ingestion-pathway zone under the standard Nuclear Regulatory Commission framework. This is a normal, nationwide feature of living near any nuclear plant rather than something unique to Dresden, but it's worth understanding if you're evaluating a parcel close to the site -- ask the county's Emergency Management office what current planning-zone participation (siren coverage, potassium iodide distribution, evacuation-route planning) actually looks like for a specific address.
