Tomato town with red rock
Jacksonville started as Gum Creek in 1847 and was renamed in 1850 for blacksmith-postmaster Jackson Smith and Dr. William Jackson. It became famous for shipping tomatoes and still holds Tomato Fest in June. The Tomato Bowl stadium was built by the WPA during the Depression from the red iron-ore rock found in these hills. Lake Jacksonville, finished in 1957 at about 1,320 acres, sits southwest of town, and Jacksonville College is near downtown.
Mid-century and older houses on hills
Census estimates for 2020–2024 put the median Jacksonville home at 1980. About half were built before 1980, about 25% before 1960, and about 19% since 2000. The older neighborhoods near downtown have many frame homes on piers. Later subdivisions and the homes around Lake Jacksonville are mostly slab, often on sloped lots.
The ground
That red rock is a clue. Cherokee County's uplands carry iron-rich sandy and clay-loam soils, and USDA data list Sacul, a clayey, moderately well-drained series, as the county's most common soil. As tabulated by FoundationSoils.com in October 2026, the data show well under 1% expansive clay inside Jacksonville itself, but about 20% of the ground with a high water table, double Tyler's share. Expansive clay covers about 14% of Cherokee County overall, so homes outside the city limits can sit on more active ground.
The hills make water the main factor. Common problems:
- Downhill settlement on cut-and-fill lots, where the fill side of the house drops over time.
- Groundwater moving downslope on top of clay layers, keeping crawl spaces and slab edges wet. A French drain across the uphill side often helps.
- Older pier-and-beam houses drifting out of level as piers and shims age. That's house leveling after any structural repair.
Buying in Jacksonville
With a mix of older homes and hillside lots, a pre-purchase foundation inspection with an elevation survey is a smart step, especially for lake-area homes and older frame houses. If a past repair shows up, ask for the warranty paperwork and the pier map.
Jacksonville questions
Is Jacksonville's soil clay?
Inside the city, USDA data show very little expansive clay, but the hills carry iron-rich clay loams and about 20% of mapped ground has a high water table. Outside town, Cherokee County has more active clay, about 14% countywide.
Do hillside homes in Jacksonville settle more?
They're more prone to settlement on the downhill or fill side, and to water moving under the house from uphill. Good drainage and an elevation survey help sort out what's happening.
Do you cover Lake Jacksonville homes?
Yes. We take requests from Jacksonville, the Lake Jacksonville area and nearby Cherokee County.
