Dirt Work & Yard Grading in Sarasota, FL

Dirt work and yard grading come before almost every new lawn we seed in Sarasota. On ground this flat, an inch or two of fall makes the difference between water that drains and water that sits against the foundation for days after a storm. Our grading work ranges from fixing one low spot to land grading on an acre lot. The same crew also handles excavation and trenching for drainage lines, so a yard that needs a buried pipe or a regraded swale can be done in one job.

Fall away from the house

UF/IFAS recommends grading a lawn so it falls 1 to 2 percent away from the house, which works out to half a foot to a foot of drop over 50 feet. On many Sarasota lots, especially older ones and those where fill has settled, the yard is flat or slopes the wrong way. The result shows up in the wet season as standing water, soggy turf and sand washed onto patios. We shoot grades, set a target and move material so the yard sheds water toward the street, a swale or a pond.

Working with the swales

Sarasota County's code requires drainage swales to keep a longitudinal slope of at least 0.2 percent and limits lot side slopes to 4 horizontal to 1 vertical along property lines, with existing drainage maintained or improved. When we regrade a yard, we tie into the swale rather than fighting it and avoid pushing water onto a neighbor's lot. Where a swale has filled in or been flattened over time, we can reshape it and stabilize it with seed and mulch or blankets.

Wet in summer, dry in spring

The flatwoods sands common in the region can hold a high water table close to the surface for months in the wet season, then dry out deeply when it drops. Grading cannot change the water table, but it can keep surface water from pooling on top of it. In spots that stay wet no matter what, we may suggest a French drain or a different plant, rather than a lawn that will struggle every summer.

Topsoil and compost

Most Florida soils are sand-based with little organic matter, and UF/IFAS notes that soil around new homes is usually worse than natural ground because construction disturbs and compacts it. Before seeding, we often bring in compost or a sandy topsoil blend and work it into the top 6 inches. UF/IFAS suggests organic amendments at 3 to 6 cubic yards per 1,000 square feet and warns against going above about 6.5, because too much organic matter can settle as it breaks down. On sand with almost no silt or clay, tilling alone does not keep the soil loose for long, so the amendment is what makes the improvement last.

Compaction from construction

Heavy equipment packs soil more than 12 inches deep, and UF/IFAS notes the effect can last for years. Compacted ground holds less water, sheds more runoff and stops roots from going down. A quick test is to push a rod into moist soil by hand; if it will not go 6 inches, the ground needs to be ripped or tilled before seeding.

Fine grading for seed or sod

The last pass is fine grading: a smooth, firm surface with no low spots, rocks no bigger than a golf ball, and paving left level with or just above the finished soil. If the yard is getting sod, we leave room for the sod's thickness. If it is getting hydroseed, we leave the surface lightly roughened so the slurry grips. Get a free estimate
