How Much Does Land Grading Cost in Connecticut?

National cost guides put land grading at $0.08 to $2.00 a square foot. Rough grading, where real soil moves, runs $1 to $2 in both guides. Regrading around a house runs $500 to $3,000 in one guide, and the average backyard runs $1,000 to $5,000. A full acre costs $15,800 to $44,535 in one guide and $17,400 to $43,600 in the other.

Those are market numbers, not our price list. All Star Wrecking does land grading in Monroe and across Fairfield County. We price each job after we look at the site. Your number moves with how much soil has to move and what sits under it.

What do national cost guides say land grading costs?

Two national cost guides publish these ranges. Both average the whole country, so treat each row as a starting point.

The first guide’s national average is $2,300. The second guide’s is $1,700, based on a 1,200 square foot lot at $1.40 a square foot. It puts a typical job at $770 to $3,000.

What is the difference between rough grading and finish grading?

Rough grading moves real soil. Both guides put it at $1 to $2 a square foot. It covers taking out a slope or shaping a yard so water drains off it.

Finish grading levels and smooths the top 1 to 3 inches. One guide puts it at $0.40 to $1.00 a square foot. On a 2,500 square foot backyard, that works out to $1,000 to $2,500. A rough grade on the same yard runs $2,500 to $5,000.

Land grading on a new house uses both. The soil goes back around the foundation, and the lot is rough graded. Once the house is up, the finish grade goes on, then topsoil and seed. The dig itself is covered in what a foundation dig costs in Connecticut.

How much does it cost to regrade a yard so water runs away from the house?

One national guide puts regrading at $500 to $1,000 for one side of a foundation. Grading all the way around the house runs $1,000 to $3,000. The second guide lists $835 to $3,000 for regrading around a foundation.

Connecticut’s state building code sets the target. Lots have to be graded to drain surface water away from foundation walls. The ground has to fall at least 6 inches within the first 10 feet, a 5 percent slope.

Backfill against a foundation can settle and leave a dip that holds water. Regrading cuts the high side down and fills the low side. Some lots have no room for the full fall, because of a lot line, a wall or a slope. There the code calls for drains or swales, and drain work is a drainage contractor’s job.

What drives the price of land grading in Fairfield County?

The ground comes first. One guide says rocky soil sits at the high end of its range. A common upland soil in Fairfield County formed in glacial till. A common ledge soil here has hard bedrock 10 to 20 inches down. Ledge and boulders slow every pass of the machine.

Slope adds work. One guide says a steep slope takes more digging and more fill dirt. The other says flat land costs less to grade than hills.

Access matters too. One guide says a city yard costs more to level than rural land, because of access and labor. A tight side yard adds time, and so does an old stone wall that stays. Trees, stumps and big rocks come out first, which one guide says adds to the cost. See what land clearing costs per acre.

Extra soil has to go somewhere. One guide says leftover dirt has to leave the site, and removal may be billed separately. Wet ground slows everything, since soil that will not hold a machine has to dry first. One guide names spring or fall, in dry weather, as the best time to regrade.

What do fill dirt, topsoil and grass seed cost?

Soil brought in is usually its own line. One guide says many grading contractors charge for fill dirt and topsoil separately.

The second guide’s fill price is the dirt alone, before anyone spreads it. Its topsoil price includes labor. One cubic yard of topsoil covers 81 square feet at 4 inches deep, the first guide says. A 2,000 square foot lawn takes about 25 cubic yards, or about $250 to $1,250 at the first guide’s prices.

Seed is the last step. We spread the topsoil and put grass seed down. Sod, plantings and irrigation are a landscaper’s work.

Do you need a permit to grade a yard in Connecticut?

Before a machine digs, a Call Before You Dig request goes in. Connecticut’s rules say anyone digging with power equipment calls the clearinghouse first.

Wetlands are the bigger question. Connecticut’s wetlands law counts filling and grading as depositing material. In a wetland or a watercourse, that takes a permit from the town inland wetlands agency. The state defines wetlands by soil type, so a dry-looking corner of a yard can still count. Watercourses include brooks and ponds.

Some town wetlands agencies also regulate work in the area around a wetland. A bigger job can also need an erosion and sediment control plan. State law has towns ask for one with a development application that disturbs more than half an acre, and a single-family house that is not part of a subdivision is exempt. We tell you what your town is likely to ask for before work starts.

How do you get a real number for your grading job?

The real number comes from your yard and the ground under it. All Star Wrecking is based in Monroe and grades yards and lots across Fairfield County with excavators.

On a new build, grading is the last step of site work, after the clearing and the dig. Regrading a driveway is its own job, covered under gravel driveways and in what a gravel driveway costs in Connecticut.
