Excavation Contractor in Franklin, TN

Excavation and Dirt Work on Franklin's Limestone Ground

Williamson County sits where Middle Tennessee's Central Basin meets the Western Highland Rim. Downtown Franklin is about 643 feet above sea level. Hills close by, like Roper's Knob, top out near 1,000 feet. That range shows up in the digging.

The upland soils here formed over limestone. Soil surveys of Middle Tennessee's limestone uplands name Talbott, Mimosa, and Maury among the common series. Talbott runs only 20 to 40 inches down to bedrock. Mimosa goes deeper than 40 inches, but it is clayey and drains slowly.

For a footing, a pad, or a utility trench, depth to rock can change across one lot. Wet clay holds water and turns to mud under tracks. We size the excavator to the ground and use grade lasers to hold elevation. Along the Harpeth River bottoms the ground is softer, so the plan changes again.

Land Clearing and Site Prep for New Builds Around Franklin

Franklin has grown fast. The 2020 census counted 83,454 people in town, up from 12,407 in 1980. Williamson County has ranked among the top ten counties in the nation for new building permits. Two kinds of ground work come out of that growth.

One is subdivision work. Westhaven off Highway 96 West was planned for about 3,400 home sites. Fieldstone Farms covers more than 800 acres off Hillsboro Road. Ladd Park has been building south of downtown along the Harpeth since 2007. Berry Farms sits on about 600 acres by I-65.

The other pattern is acreage. West of town toward Leiper's Fork, houses go up on tracts of five acres and more. Those lots come wooded and sloped, with long driveways and septic instead of city sewer. We take trees and brush down, pull stumps with the excavator thumb, and move into building pads and grading.

Septic is its own step out in the county. Williamson County handles that permitting through its Department of Sewage Disposal Management. The application wants a soils map from a certified soil scientist. We clear the area and do the digging, and a licensed installer puts in the system.

Erosion Control and Drainage in the Harpeth River Watershed

The Harpeth River runs through downtown Franklin, and Sharp Branch runs beside and under the streets there. Spencer Creek and the West Harpeth feed the river around town. In May 2010 the Harpeth crested at 35.32 feet at Franklin, with 7.25 inches of rain on May 2 alone. FEMA and the Army Corps redrew the flood maps afterward.

Water shapes most of the ground work here. Clay slopes shed a hard rain instead of soaking it up, so bare dirt moves with it. In older parts of town that same clay leaves standing water in yards and against foundations. French drains and regrading the elevation move that water away from the house.

Inside the city, Franklin permits land disturbing work. Grading and stormwater permits apply past 10,000 square feet of disturbance. A stabilized construction entrance has to be in within 24 hours of grading. Sites get inspected weekly and again around a predicted quarter inch of rain.

Wilson Forestry and Excavating is an approved erosion control contractor with TDEC. On a Franklin site that means silt fence, rock check dams, stabilized entrances, and riprap at outlets. Seeding and matting hold the slopes that stay bare. The point of erosion control is keeping clay off the pavement and out of the creek.

Gravel Driveways and Getting Around Franklin

Franklin is laid out around a few main routes. Interstate 65 crosses the east side with four city exits. US 31 and US 431 meet downtown, and Columbia Avenue and Lewisburg Pike carry traffic south. Mack Hatcher Memorial Parkway loops the north and west sides, and Carothers Parkway runs the Cool Springs office corridor.

Off those routes the pikes run out into the county. Hillsboro Road, Del Rio Pike, Carters Creek Pike, and Southall Road head toward acreage and older homes. A place back there needs a real road before a house goes up. We cut the bed, build the base, then crown and ditch it so a gravel driveway sheds water.

Franklin is about an hour and a half of driving from Woodlawn. That puts it at the far edge of the ground we cover. We travel there for excavation and land work, and we plan it in longer stretches. Call or text (931) 572-8673 for a free estimate on a Franklin job.
