Site clearing is the first phase of site work, and the rest of the schedule leans on it. We clear and grub, strip and stockpile topsoil, haul off debris and rough grade so the next crew can start on time.

Site Clearing for Builders in the Treasure Valley

Clearing looks like the easy part of a build, but it sets up everything else. If roots stay in the ground, the pad settles. If the topsoil pile lands where the sewer trench goes, it gets moved twice. If the silt fence the plans show isn't up before the first rain, the inspector notices. Doing the first phase in the right order saves time in every phase after it.

We do site clearing for home builders, contractors and owner-builders in Boise, Meridian, Nampa, Kuna, Eagle, Middleton and Caldwell. Most of these jobs are a new home, a custom build on acreage, or a shop with a driveway and utilities, all built from a site plan.

The Site Clearing Sequence

1. Locates and layout

We call Digline (811) at least two business days before breaking ground, as Idaho law requires. We also go over the site plan for the limits of disturbance, trees marked to stay, setbacks and survey stakes. A stake knocked over in the first hour means the surveyor has to come back, so we work around them.

2. Erosion control

When the plans call for erosion control, it usually goes in before clearing starts. That can mean silt fence along the low side of the site, a gravel construction entrance to keep mud off the street, and protection around nearby storm drains. We put in what the plans show and keep it working while we're on site.

3. Clear and grub

Clearing takes off what's above ground, like trees, brush, grass, old fencing and surface debris. Grubbing takes out what's below it, meaning stumps, root balls and buried roots inside the building and paving areas. On an old Canyon County farm field, that may be little more than weeds. On a site near the Boise River, it can mean cottonwood stumps and thick roots.

4. Strip and stockpile topsoil

Topsoil and organic material come off the building pad, driveway and anywhere fill will go. Depth varies. Old farm ground can have a deep organic layer, and the plans or a soils report often say how deep to strip. The stockpile goes where it won't block trenches, deliveries or drainage. Good topsoil gets saved for topsoil spreading at the end of the job.

5. Debris removal and hauling

Stumps, brush, rock, old concrete and anything else that can't stay get sorted and hauled. Clean green waste, concrete and metal each have their own place to go, which keeps disposal costs down. More on that under debris removal and dirt hauling.

6. Rough grade

Once the site is stripped, we rough grade it so it drains and the next crew has a workable surface. Stump holes get filled and compacted, high spots come down, and water gets a path away from where the foundation will sit. Pad work picks up from there under site preparation and grading or land grading for larger areas.

What Slows Site Clearing Down

Most delays on a clearing job come from the ground itself or from water. These are the ones we see most around the valley:

  • Wet clay. Spring rain turns clay into mud that's hard to work and tracks onto the street.
  • Caliche and basalt. Hardpan in Meridian, Nampa and Kuna, and basalt in parts of Kuna and southeast Boise, slow down stump and root removal.
  • Shallow groundwater. Near the river in Eagle and Garden City, stump holes can fill with water.
  • Irrigation season. From roughly April to October, ditches along the site are running and shouldn't be disturbed without the irrigation district's OK.
  • Buried surprises. Old septic tanks, wells, foundations and debris-filled fill turn up on older properties.

Permits and Plans

Site clearing usually happens under the project's building or site development permit, not a separate one. Sites that disturb an acre or more generally need construction stormwater permit coverage before ground is broken, and the permit holder, usually the owner or builder, is responsible for that plan. Smaller sites can still have erosion control rules from the city or county. Your plans or the permit office will say what's needed.

What Affects the Cost

The biggest factors are the size of the site, how much vegetation and how many stumps there are, topsoil depth, whether topsoil stays on site or gets hauled, and how much erosion control the plans require. Access and haul distance matter too. We give free estimates from the site plan and a visit.

Clearing raw acreage with no build planned is covered on our land clearing page. For a single home lot, see lot clearing, and for business and development work, see commercial site clearing.

Frequently Asked Questions

What does clear and grub mean?

Clearing removes everything above ground, like trees, brush, grass and debris. Grubbing removes what's left below ground, like stumps and roots. Together they leave the building and paving areas free of organic material that would rot and settle later.

How deep should topsoil be stripped on a building site?

It depends on the site. Some ground has only a few inches of organic soil, while old farm fields can have much more. The plans or soils report often give a depth, and otherwise we strip until we reach firm native soil.

Who is responsible for erosion control on a construction site?

The permit holder, usually the owner or builder, is responsible for the erosion control plan and its inspections. We install the measures the plans call for, like silt fence and a construction entrance, and keep them working while we're on site.

Can you work from my site plan and survey stakes?

Yes. We clear to the limits shown on the site plan, keep the trees marked to stay, and work around the surveyor's stakes. If something on the plan doesn't match what's on the ground, we'll call you before going further.

What should I send you for a site clearing bid?

The site plan, any erosion control sheet, the soils report if there is one, and your target start date. Photos help too. A quick site visit usually fills in the rest.

What happens if you find an old well or septic tank?

We stop and let you know. Old wells usually need to be closed by a licensed well driller under state rules, and old septic tanks need to be pumped and removed or filled. Your builder or the health district can tell you what's required.
