What Is Land Clearing? Methods, Equipment, Permits and What to Expect in Houston

The land clearing process has four jobs in it: cutting, grubbing, dirt work and debris. Cutting is clearing away the trees and other vegetation above ground. Grubbing is pulling the stumps and roots so you can remove trees for good. Dirt work is grading: moving dirt so water leaves the lot where you want it to. Debris is what you do with the pile: mulch it, haul it or burn it. Land clearing can also stop short of all four. Forestry mulching cuts and leaves the roots in the ground. Selective clearing, or targeted clearing, takes certain types of vegetation and leaves the oaks. Brush and tree removal on a lot you plan to build on usually needs all four. A land clearing project on a half acre and one on 50 acres are the same four jobs at different sizes; the size of the area to be cleared sets the days, and vegetation sets the price. Is land clearing necessary? Only if something goes on the lot next and the ground has to be usable for it. Need to clear just the pad? That's lot clearing, one day. What it doesn't include: concrete, septic or knocking down a house. I know people who do those. The word land-clearing covers a lot of ground, so when you call, say what the lot is for.

Four machines do nearly all the land clearing around Houston, and two of them are mine. A skid steer with a mulching head eats anything under 8 inches and does 1 to 3 acres a day. A dedicated high-horsepower mulcher runs an 11-foot drum, eats anything, and does 4 to 8 acres a day. Bulldozers and excavators are the traditional heavy machinery: the dozer pushes and grades, the excavator with a thumb or root rake pulls stumps and loads trucks. Specialized equipment matters less than the operator's feel for the ground. A dozer sinks where a mulcher floats, because wide tracks spread 20,000 pounds over a footprint the dozer can't match. A bush hog, by the way, is a mower; it won't touch a 2-inch yaupon stem. Tree removal services and a tree service take single yard trees with a bucket truck; land clearing services take the whole lot with a machine. On our jobs in Waller County the skid steer does the lot and the big machine stays on the trailer unless the pine is thick. Machinery is a cost you pay by the day, so the right machine is the one that finishes your lot in the fewest days. Ask which machine your lot gets before you sign anything.

No permit is needed to clear your own land outside the mapped floodplain in most of Harris County. Inside the floodplain, Harris County Engineering issues a development permit before dirt moves, and Harris County Flood Control District reviews drainage. The FEMA flood map tells you which side of the line you're on; Janine pulls it for every address before we quote. That line is important in areas along the bayous and Cypress Creek, where half the lots sit inside it. Inside the City of Houston the tree ordinance applies to commercial sites. Katy, Fulshear, Sugar Land, Pearland and League City have their own tree rules for new builds, and most HOAs and MUDs want a letter. Brazoria and Galveston near the marsh may need a USACE wetland delineation first. Burning is legal outside the city under TCEQ rules unless the county has a burn ban on, but the risk of the fire spreading in a dry August is yours and the fine is yours too. Depending on the location, the answer is a phone call or a six-week wait. Clearing a plot of land in the floodplain without one means a stop-work order and a bill to put the dirt back. Ask before the machine rolls.

After clearing comes the grade, then seeding or a slab, and the first storm decides how well the first two went. The grade sets where water leaves the lot; on gumbo clay that means a crown and a swale, because the clay won't soak it in. Soil erosion on bare dirt starts the first week, so we leave the mulch layer where nothing gets built and seed bermuda or bahia on the rest once the soil is above 65 degrees. On a mulched lot you can walk it the next morning and plant grass in spring. On a grubbed lot, access for construction vehicles needs a rock drive before the form crew comes. Effective land clearing is clearing land and preparing it for the next step, not just the cutting. Land preparation for a house means the pad 18 inches above the road crown, above base flood elevation on the FEMA map, and site preparation for a shop means the same with a wider drive. A cleared lot that sits a year will overgrow; every tallow shrub comes back from the root crown and the privet seeds in. Preparing land and then leaving it is paying twice. Plan the next step before the machine leaves.
