Gravel and Limerock Driveways in Callahan, FL
A gravel or limerock driveway on flat, sandy ground near Callahan, Hilliard and Bryceville comes down to water. It has to cross the roadside ditch with the right permit and pipe, sit high enough to stay firm when the water table rises, and use rock that holds up on sand. This guide follows the drive from the road to the house: who permits the connection, why Nassau County wants concrete where your drive meets its road, the culvert, the bed, the rock, Sunshine 811 and published national costs.
First, whose road is it?
Each road owner permits its own connections: Nassau County for a county road, the Florida Department of Transportation for a state highway, and the town for a street inside Callahan or Hilliard. Not sure which you have? Ask the county or FDOT before anything is scheduled.
Know where the road's land ends, too. Nassau County's right-of-way FAQ warns that "Some residents do not understand that the public right of way extends into what they consider to be their private property." It puts typical residential rights-of-way at about 50 to 60 feet and arterials at over 100. Your title company can confirm the easements on your parcel.
On a Nassau County road
The same FAQ is direct: "All driveway and/or drainage connections to and/or across public right-of-way shall require a permit." For a rock drive, that means:
- The county sizes the pipe. The County Engineer or a designee decides the culvert's size and invert depth.
- The connection is concrete. "Driveway connections shall be constructed with a minimum of six (6) inches of reinforced concrete," at 3,000 psi. "Swale driveways may be allowed, if approved by the County Engineer or their designee," and where no pipe is needed, the drive must follow the existing flow line of the roadside swale.
- The clock runs. A permit covers up to 12 months of work, or 18 with prior written approval; after that, it's a new application and fees.
- Where to apply. At 96161 Nassau Place in Yulee or through the county's online Development Services application, which posts the fees.
So on a county road, the permitted connection is concrete and your limerock or gravel starts behind it. Ask the county where that connection ends on your lot, and make sure the quote covers both.
On a state highway
FDOT takes driveway connections to state highways on its Driveway/Connection Application for All Categories, Form 850-040-15 (rule 14-96.005), filed through its One-Stop Permitting site or on paper from the local area Maintenance Engineer. For Nassau County that's FDOT's Jacksonville Operations office, 2198 Edison Avenue, (904) 360-5200. The application asks for the "location and type of drainage features existing and proposed within the right of way" and isn't accepted without its fee, so ask the office which category and fee fit your drive.
Inside Hilliard or Callahan
Hilliard's code (Sec. 42-31) bars culvert pipe in a public right-of-way without a permit; Town Hall is (904) 845-3555. In the Town of Callahan, ask the Building and Zoning Administrator, (904) 879-3801. Tree rules in both towns are in the permits guide.
The culvert
The invert depth is the height of the bottom of the pipe, and the county sets it so the ditch keeps draining past your drive. Hold the quote to the permit: pipe diameter and length, material, how the ends are finished, how the fill around it is compacted, and who buys the pipe.
The bed: flat sand, hardpan, high water
Much of this land is flat sand with a water table that sits high for part of the year, often over a dark hardpan layer. A drive built at yard level sits in that water when it's up. Settle these before the rock is ordered:
- How far above the surrounding ground will the bed be raised, and with what fill?
- Where will the drive's own runoff go, and does that keep it off the septic area?
- Are pine stumps and palmetto roots coming out of the path? Mulched roots left under a driveway base decay, and the drive settles over them.
- Is fabric going under the rock, how thick is the packed rock, and what happens to the schedule if the ground is soaked?
Two more checks before the route is staked. The FWC's gopher tortoise FAQ says no permit is needed "if all gopher tortoise burrows are avoided by 25 feet in all directions." And a drive across a cypress dome or other wetland is a state permit question; rule 62-330.020 also counts more than 4,000 square feet of impervious and semi-impervious surface used by vehicles, which a 10-foot-wide drive passes once it runs longer than 400 feet. Ask the St. Johns River Water Management District, (904) 730-6270, whether yours counts.
Limerock, crushed concrete, shell or stone
Limerock was written right into FDOT's road specifications. A 2016 report for FDOT notes the department "recently changed its specification language eliminating the use of the word 'limerock' from Section 911," its base rock specification.
Crushed concrete is used for road base here too: the same report says recycled concrete aggregate "is used beneficially as a road base material" in Florida, and FDOT's recycled materials list puts it under Section 911. The report also flagged high-pH water leaching from it as harmful to aluminized storm water pipe, so if the culvert will be aluminized metal, raise that with the County Engineer.
Shell and stone are sold for drives too. Bob Vila's guide (updated July 2022) priced crushed clamshells at about $50 a ton, and HomeServe (October 2025) lists #57 crushed stone at $120 to $255 a ton. On a county road, any of them stops where the concrete connection begins.
Call Sunshine 811 before the ditch is cut
Trenching the crossing and cutting the bed are both excavation. Florida law (§ 556.105, F.S.) requires notice at least 2 full business days ahead, and a locate stays valid for 30 calendar days. The single-family owner's exemption (§ 556.108) only reaches 10 inches deep, well short of a culvert trench. Call 811 or (800) 432-4770.
What a rock driveway costs
HomeServe's October 2025 guide prices a 100-foot gravel drive put in by a pro at $4,000 to $6,000, and expects regrading and fresh material every one to three years. Inch Calculator (updated August 2023) puts the usual price at $1 to $3 a square foot, with most owners paying around $2,000 for one 100 feet long and 10 feet wide.
Neither covers the county's concrete connection, the culvert, fill to lift the bed off low ground, stump removal or permit fees. They're national yardsticks, not west Nassau prices. Go by the written price you get once a contractor has walked your drive's path from the road.
Driveway questions
Can the limerock run right up to the pavement on a county road?
Not under the county's FAQ, which calls for reinforced concrete in the connection. Ask the County Engineer whether a swale driveway is allowed on your road.
Who decides the culvert size, the contractor or the county?
On a county road, the County Engineer. On a state highway, FDOT reviews the drainage on its application. In Hilliard, the town permits the pipe.
Does a field or timber road entrance need a county permit?
The county's FAQ doesn't list an exception for farm or timber entrances, so ask Nassau County before cutting one in. Forestry road crossings over creeks or wetlands also have a state notice; see clearing after logging.
When should a drive on low ground be built?
When the water table is down and the ditch is dry or low. Ask how rain days and soaked ground affect the price.
