Grading and
Site Work
Grading is the dirt work that happens before paving. Done right, it moves water away and gives your driveway or lot a base that holds. We grade, dig and prep it ourselves.

ABOUT US
The step that decides if pavement lasts
Most paving companies hire out the dirt work, then pave over whatever they get. On our clay soil, that is why their work cracks in a couple of winters. We grade and pave with one crew, so the ground is right before the asphalt goes down.
One crew grades and paves, so the base is right before the asphalt goes down- Compaction tested to 95 percent on every job
- Caltrans Class 2 base rock, laid and packed in lifts
- Drainage and slope built for Sonoma County clay soil
How our grading process works
We read the plans and stake the grade, then cut and fill to bring the site to height. We lay Caltrans Class 2 base in lifts and compact each one to 95 percent, testing as we go. We shape the slope for drainage and hand it off build-ready, with the density results documented for inspection.

Our grading and site work covers pads, lots, roads and driveways across Sonoma County. We cut and fill to the right grade, build the base in lifts, and slope the ground so water runs off and away from what we build on top. We test compaction and document it for your inspector.

Grading and Site WorkWhat we grade, and the permits
We are the same crew that paves on top of the grade. Most paving companies cannot say that, because they hire the dirt work out.
When you need a county grading permit
Sonoma County requires a permit before you move more than 50 cubic yards of dirt, cut or fill deeper than 3 feet, or cut a steep slope over 5 feet tall. Bigger jobs need a plan drawn by an engineer. We grade to these rules and handle the permit. Confirm yours with Permit Sonoma.
