Grading that moves winter rain away from your home

Grading and Drainage is the dirt work that decides where rain goes on your property. Trinity Paving and Concrete is a paving contractor in Dixon, and every driveway and pad we build starts with grading. We also take on yards that stay soggy all winter. Our work reaches about 40 miles around Dixon.

As a grading contractor, we cut high spots and fill low ones before anything gets paved. That groundwork is where asphalt driveway paving starts. Drainage work adds French drains and catch basins where water collects. Call or text (707) 396-7730, and we will look at the site and put the quote in writing.

What We Handle

  • Site grading for driveways and pads
  • Subgrade prep and compaction before paving
  • Catch basins and drainage boxes at low spots
  • French drains for soggy yards
  • Culverts and driveway ditch crossings
  • Surface grading that carries water away from the house
  • Grading for rural property and long farm driveways

Why Does Water Stand on Flat Clay Lots Around Dixon?

NRCS soil maps show most of Dixon as well-drained silty clay loam on slopes of 0 to 2 percent. In places, though, the ground is expansive clay that takes in water slowly or very slowly. Southwest of town, some soils formed under poorly drained conditions.

Rain comes in a short season here. NOAA normals for the Davis station, north of Dixon, show about 19 inches a year. About 84 percent of it falls from November through March. Clay that takes in water slowly gets little time to dry out between storms.

On ground this flat, water sits in low spots and along the house. Inside Dixon, storm drains carry runoff through detention ponds into the Dixon Resource Conservation District's ditches south of town. Those ditches drain on to Hass Slough and were built for moderate winter storms. Grading gets the water off your lot and into that system.

What a Grading Contractor Does Before Paving

Every driveway and pad starts with the subgrade, the native soil under the base rock. We cut it to grade and shape it so water runs off. Then the subgrade is compacted before the first layer of base rock goes on. Soft spots that give under load get dug out and rebuilt.

Expansive clay makes this step matter more, because it cracks when dry and swells when wet. Dixon's street design standards assume a weak subgrade unless a soil test shows otherwise. An asphalt pavement trade association's driveway guide says clay topsoil should be removed or modified. The same care goes into a gravel driveway that may be paved later.

Sloped lots bring their own grading work. Where a cut leaves a bank too steep to stand, a retaining wall holds the soil back. Water behind the wall needs a way out, so drain rock and a perforated pipe go in with it.

Yard Drainage and Driveway Culverts

A French drain is a trench filled with gravel around a perforated pipe. It takes in water from soggy ground and carries it to an outlet lower than the wet spot. It suits lawns and side yards that stay wet long after a storm.

A catch basin, or drainage box, sits at a low spot and takes in surface water through a grate. A solid pipe carries that water to an outlet. An outlet at the curb sits in the public right-of-way. In Dixon, that takes an encroachment permit from the city's Engineering Department.

Rural driveways often cross a roadside ditch on a culvert. At a Solano County road, a culvert under the driveway must be at least 15 inches across. The county's road standards size culverts for a ten-year storm, with rock or a headwall where the ditch can erode. A pipe set too high or too small backs water onto the drive.

FAQ

Grading and Drainage Questions, Answered

Common questions about grading and drainage around Dixon and the towns of Solano, Yolo and Sacramento counties. If yours is not here, call or text and ask.

Call (707) 396-7730

Do I need a grading permit to grade my lot or driveway?
Outside city limits, Solano County's grading list exempts cuts and fills under 50 cubic yards, with depth and area limits. A fill that changes how water leaves the site does not qualify. In Dixon, a city handout notes that grading may need Planning Division review even without a building permit. The city permit office answers that question, and we point you there.
How much does grading and drainage cost?
The price follows how much soil has to move and whether fill or base rock gets brought in. Drain work adds the length of pipe and the number of catch basins. Tight access and a long run to the outlet add to it. We look at the site first and put the quote in writing.
Do I need a French drain or a catch basin?
It depends on where the water comes from. A catch basin suits surface water that pools at one low spot, like the foot of a driveway. A French drain suits ground that stays soggy, since its perforated pipe takes in water along its length. Some yards need both.
How much should the ground slope away from my house?
The California Residential Code calls for the ground to fall at least 6 inches in the first 10 feet. Paving and other hard surfaces within 10 feet of the house must slope at least 2 percent away. Where a wall or a lot line leaves no room, the code calls for drains or swales instead. We set the grade with those numbers in mind.
Will 811 mark the lines before you dig?
California's one-call law covers grading, so an 811 ticket goes in at least two working days ahead. The utilities then mark the lines they own. Private lines, like sprinkler pipe or power to a shed, are not marked. Show us where yours run before work starts.
When is the right time to fix a drainage problem?
Grading suits the dry months, when clay is easier to work and compact. In Benicia, city code restricts grading from October 15 to April 15 unless the city approves it. Winter is still the time to see where water sits. Photos of the puddles during a storm help us plan the fix.
