Gravel Driveways in Maury County, TN
A gravel driveway in Maury County is two projects. One is approval at the road, which depends on whether the drive meets a state route, a county road, or a street in Columbia, Spring Hill, or Mount Pleasant. The other is a bed that stays firm on clay, chert, and limestone without sending its runoff into a sinkhole. Here's each in turn, plus the base rock Middle Tennessee quarries sell, Tennessee 811, and dated national prices.
Who approves the entrance
Whoever owns the road decides how a new drive ties into it, so find out which kind you're on before anyone prices a culvert. Offices and numbers checked October 2026.
| The drive meets... | Who to ask |
|---|---|
| A state route | TDOT. The county's building permit application lists 615-350-4300 for state roads. |
| A county road | Maury County Highway Department, 1210 Industrial Park Road, 931-375-6203. |
| A Columbia street | Columbia Development Services, 931-560-1560, under the city's engineering standards below. |
| A Spring Hill or Mount Pleasant street | Spring Hill Development Services, (931) 451-0904; Mount Pleasant City Hall, (931) 379-7717. |
Maury County's building permit application (revised June 6, 2025) puts it plainly: "On county roads, driveway connections must be approved by the Maury County Highway Department." For a new house, the same form asks for a TDEC septic permit and an address from the E911 Office (931-381-3190), so settle the entrance alongside them.
On a state route
TDOT's entrance permit page says a permit is needed before a driveway is built on state highway right-of-way, or an existing one is changed: "Property owners must obtain a permit from TDOT." For a home, it sends you to the local TDOT office; the main line is (615) 741-2848.
TDOT's application form (revised August 2017) has the owner take on "the entire cost of constructing and maintaining an approved driveway access" and build to TDOT's driveway manual. Its bond rule says "Residential applicants are exempt," the permit lapses if the drive isn't finished by the date on it, and its property-use boxes include "Single Family Residential/Farm."
Inside Columbia
Columbia's Engineering Standards and Specifications (September 12, 2024) shape what a gravel drive looks like where it meets a city street:
- A paved apron first. Asphalt or concrete to the edge of the right-of-way (concrete where there's curb and sidewalk), and "Where the remainder of driveways are un-paved surfaces, the apron shall be a minimum of thirty (30) feet in length." The gravel starts behind it.
- Grade limits. A residential drive can't be steeper than 10 percent inside the right-of-way, or 20 percent anywhere else.
- Culverts. "The minimum size for driveway culverts shall be fifteen (15) inches in diameter," with concrete or masonry headwalls and endwalls. Concrete, plastic, and metal pipe are all allowed, with reinforced concrete required where an entrance is heavily traveled or could flood the right-of-way or a building.
- Sinkholes. Roadways and structures "shall not be located within the extents of a sinkhole."
Development Services can tell you which permit or review covers your drive.
The pipe under the drive
Where the entrance crosses a roadside ditch, a culvert carries the ditch water underneath. The county's application gives no pipe size for county roads, so ask the Highway Department what diameter, material, and depth it wants, and whether anyone inspects the pipe before it's covered. Then check that the quote names that same pipe, its length, how the ends are finished, and who buys it.
Laying out the route: sinkholes and slope
Keep runoff away from sinkholes. A gravel drive gathers water and sends it somewhere through its ditches, turnouts, and culvert. TDEC's karst guidance regulates a sinkhole as a Class V injection well when development changes the water reaching it, including "directing stormwater to the subsurface by pipe or other conveyance towards the sinkhole." Point the drive's water anywhere but a sinkhole. Filling one escapes those rules only if it isn't otherwise regulated, and that turns on how the land is being developed, so ask the TDEC Columbia Environmental Field Office, (931) 380-3371, first.
Mind the steep ground. The county's 2026 zoning ordinance allows drives on slopes past 25 percent, but from 25 to 50 percent they need a geotechnical study, and none may cross a slope over 50 percent. On a hillside, call Maury County Building & Zoning, 931-375-3006, before the route is staked; the permits guide has the full slope rules.
What to ask for at the quarry
Ask around Middle Tennessee for driveway base and you'll likely hear "Grade D" or "pug." A Tennessee aggregate listing describes Grade D base pug as "a durable blend of crushed stone and stone dust" for road base and driveways. The name comes from road specs: Metro Nashville's base course section, built on TDOT Section 303, calls for "Class A aggregate grading D" and samples it at the pugmill where it's mixed. The fines are what let it pack hard.
The rock is only as good as what's under it. Ask the contractor:
- Will topsoil and soft, wet clay come out of the path, and how thick will the base be once it's compacted?
- How will the surface be crowned so water runs off the sides, and where does that water go next?
- If a limestone ledge turns up in the path, how does the price handle it?
- Will stumps in the path be dug out rather than ground? Roots left under a drive rot, and the surface sinks. Stump grinding and removal explains.
Tennessee 811 before the bed is cut
Cutting the bed, trenching for the culvert, and grading all move earth, which Tennessee's damage prevention rules count as excavation for homeowners and contractors alike. Give notice three to ten working days ahead by dialing 811 or calling 800-351-1111. The person running the machine needs their own ticket, and private lines such as a well line to the house may not be marked.
What a gravel drive costs
HomeServe's October 2025 cost guide puts a professionally installed gravel driveway at $1.25 to $3 per square foot nationally, with site preparation (grading, excavation, or clearing) at $700 to $2,500 and crusher run or road-base gravel at $24 to $34 a ton.
By those figures, a drive 10 feet wide and 300 feet long (3,000 square feet) would run about $3,750 to $9,000 before site prep. Clearing the route, pulling stumps, ledge rock, a culvert with headwalls, a paved city apron, and permit fees can push past that. These are national numbers, not Maury County prices. Budget from the price a contractor puts on paper after seeing the ground the drive will cross.
Gravel driveway questions
Does a farm gate off a county road need approval too?
The county's rule covers driveway connections on county roads and doesn't carve out farm entrances, so call the Highway Department, 931-375-6203, before cutting one in.
Who files for the entrance, the owner or the contractor?
TDOT says the property owner obtains its permit. For a county road or city street, ask that office who may apply, and put the answer in the agreement.
How deep should the gravel be?
Houzz's cost guide says gravel "needs to be poured four to six inches deep" to carry a car. A truck, camper, or loaded cattle trailer is a different load, so tell the contractor what will use the drive and ask what compacted depth the price includes.
How often does a gravel drive need work?
HomeServe says regrading and adding material typically happens every one to three years, with new rock at roughly $0.25 to $1 per square foot.
