Lakeshore Ground in Harrison

Excavation contractors in Harrison work in a lakeside community with an unusual history. Harrison was the Hamilton County seat from 1840 until 1870. When TVA completed Chickamauga Dam in 1940, much of the town was flooded; foundations, roads and guard rails can still be seen around Harrison Bay. Today the CDP has 7,902 residents (2020), and roughly a fifth of its area is water.

Lake rules

Shoreline lots on Chickamauga Lake fall under TVA rules for grading, fill and docks. We check before any work near the water.

Old foundations

Remnants of the old town around Harrison Bay are a reminder that buried foundations and old fill can turn up in this area.

Parks and recreation

Harrison Bay State Park, a 1,200-acre TVA-built park from the 1930s, and Bear Trace golf course are here. Homes near them are mostly on larger lots with septic systems.

Soils near the lake

Low ground near the lake is softer and wetter. Pads there need firm subgrade, sometimes with stone and fabric. Upland lots are clay over limestone, with the usual sinkhole caution.

Larger lots

Most homes outside the old town core are on larger lots with septic systems and private drives.

Landfill traffic

The Hamilton County Landfill is in Harrison. Truck traffic on nearby roads is heavy at times, and we plan around it.

Planning near Harrison Bay
