Buying Land in Pulaski County, Illinois
Pulaski County, seat Mound City, sits at Illinois's southern tip -- one of only 17 Illinois counties governed by a commission rather than a system of townships. It borders the Cache River's Ramsar-recognized wetlands and has real, documented 2011 flood history. Here is what that means for anyone evaluating land here.
Government and zoning: one of 17 counties with no townships, and a real documentation gap
Pulaski County is one of only 17 Illinois counties -- alongside Alexander, Calhoun, Edwards, Hardin, Johnson, Massac, Menard, Monroe, Morgan, Perry, Pope, Randolph, Scott, Union, Wabash, and Williamson -- that operate under a commission form of government with no townships at all. A three-member County Board handles both the legislative and executive functions townships would otherwise split off in the other 85 Illinois counties. The county itself was carved out of Alexander and Johnson Counties in 1843; its original seat, Caledonia, was replaced by Mound City in 1868.
Where this page has to be more candid than most: this research pass could not locate a dated, currently posted Pulaski County zoning ordinance or confirm a specific zoning-administrator title, unlike neighboring Randolph County, which has a well-documented Land Resource Management office. If you're evaluating a specific unincorporated Pulaski County parcel, treat this as a call-first situation -- confirm current zoning status, any permitted-use restrictions, and building-permit requirements directly with the County Clerk's office at the Mound City courthouse rather than relying on an assumption either way. Land inside Mound City, Mounds, Ullin, or any other incorporated municipality falls under that municipality's own zoning authority instead.
The Cache River wetlands: a border, not a burden, but worth checking directly
Part of Pulaski County borders one of the most ecologically significant wetland systems in the Midwest: the Cache River State Natural Area, a remnant bald cypress-tupelo swamp recognized in 1996 as a Ramsar Convention 'Wetland of International Importance' -- reportedly only the 19th U.S. wetland to receive that designation. The natural area's protected units (Little Black Slough, Lower Cache River Swamps, and Glass Hill) span Johnson, Massac, and Pulaski Counties together, rather than sitting entirely within any one of them.
Because this project already covers that same wetland system in depth on a standalone Johnson County page, this hub treats it as important context rather than repeating that page's material here. If you're looking at land anywhere near the Cache River in Pulaski County, read that page for what a Ramsar designation and state natural area boundary do -- and don't -- mean for a nearby private parcel, and get a site-specific wetland delineation before assuming where a boundary actually falls.
Flood history: the 2011 Len Small Levee breach and Main Ditch
Pulaski County has real, documented flood-control history tied to its position near the Ohio-Mississippi confluence. On May 2, 2011, during a historic regional flood, the privately maintained Len Small Levee failed; Ohio River floodwater pushed through the breach and into Main Ditch, and combined with a rain-swollen Cache River and an already-saturated internal drainage network to flood parts of Massac, Pulaski, and Alexander Counties as far west as Olive Branch and Horseshoe Lake. Locally, advocates reportedly pushed FEMA -- while it was remapping Pulaski County's flood zones -- to survey Main Ditch specifically and build it into the county's flood model, a Pulaski-specific detail distinct from the broader regional flood story.
None of this means land here is uninsurable, but it does mean flood-zone due diligence isn't optional for a parcel anywhere near the Cache River, Main Ditch, or the Ohio River bottoms. Check current FEMA Flood Insurance Rate Maps for the specific parcel, and ask the county directly about any levee-district coverage and its current maintenance status.
A rural, lower-income county: what that can mean for land and infrastructure
Pulaski County's population was 5,193 at the 2020 Census and has continued declining since. Per capita income (roughly $18,400 in recent Census Bureau estimates) runs well below state and national averages, and both unemployment and child poverty rates rank above state and national norms; poverty is especially pronounced in the city of Mounds. For a land buyer, this context is worth keeping in mind less as a warning and more as a reason to verify rather than assume: confirm current utility hookups, road-maintenance responsibility, and neighboring-parcel occupancy directly for any specific property rather than relying on an older listing description or aerial photo.
Septic, assessor, and recorder contacts
Pulaski County does not run its own health department -- environmental health services, including private sewage disposal (septic) permitting and private water-supply inspections, run through the Southern Seven Health Department, a regional multi-county agency headquartered right in Pulaski County (Ullin), also serving Alexander, Hardin, Johnson, Massac, Pope, and Union Counties under the statewide IDPH Title 77 Part 905 framework.
County-level records offices are consolidated at the courthouse in Mound City (500 Illinois Ave.): the Chief County Assessment Officer handles property valuation, and the County Clerk & Recorder's office handles recorded deeds, easements, plats, and GIS/property mapping requests for a specific parcel.
Who to Call Before Buying Land in Pulaski County
