R & M Grading, Inc.
Grading, excavation and site work from a Napa contractor that runs its own trucks off Big Ranch Road.
About
North of downtown Napa, where Big Ranch Road leaves the subdivisions behind and runs out between vineyard blocks, R & M Grading, Inc. keeps its base at number 2200. Alex Rodriguez is the owner on the chamber's record. The company is registered with the U.S. Department of Transportation under USDOT number 2848134 as an intrastate carrier operating two power units, and that federal record, last updated in November 2025, carries the same Big Ranch Road address and the same phone number as this listing.
Earthwork and hauling
The name and the directory filing under excavation work point to grading and earthmoving, and the DOT registration shows the company hauls on its own trucks within California. A grading contractor in Napa County usually takes on rough and finish grading for house pads and driveways, cut-and-fill work to set drainage, trenching for water, sewer and electrical lines, foundation digs, and clearing and hauling away spoils, rock and demolition debris. On vineyard and rural parcels the work often extends to access roads, culverts and erosion control ahead of the winter rains.
There is no company website describing its own services, so ask which of these jobs it takes and whether it works for homeowners as well as builders and wineries.
Hiring a grading crew
Ask for the contractor's state licence number and look it up at cslb.ca.gov to see its classifications and status; earthwork usually falls under the C-12 earthwork and paving class or the Class A general engineering class. Find out who pulls the grading permit from the City of Napa or Napa County, and whether the quote includes compaction testing, erosion-control measures and haul-off. Call 811 before any digging so buried utilities get marked. California caps a home-improvement down payment at ten percent of the contract or one thousand dollars, whichever is less, so question any larger deposit.
Napa Valley coverage
From the north end of Napa the valley floor opens toward Yountville, Oakville and Rutherford, with Saint Helena and Calistoga farther up Highway 29 and Angwin on the hill above. American Canyon lies south, near the county line. Those communities and the unincorporated land between them form the natural reach of a Napa County grading outfit.

Services
Typical for this type of businessRough and finish grading to shape house pads, driveways and yards to plan, setting slopes so storm water drains away from foundations and toward approved outlets.
Digging footings, basements and pool shells with the depth and compaction the engineer's plans call for, and stockpiling or hauling the spoils.
Trenches for water, sewer, septic, gas and electrical lines, dug to the depth the utility or county requires and backfilled and compacted after inspection.
Removing dirt, rock and debris from a site and bringing in base rock or fill; the company's USDOT registration shows it runs its own trucks within California.
Building and regrading gravel access roads, installing culverts and shaping ditches on vineyard and ranch parcels, often with erosion control before the rainy season.
Taking down small structures, removing old slabs and clearing brush and stumps so a lot is ready for grading and new construction.

Common questions
Typical for this type of businessDo I need a permit to grade my property in Napa County?
Often, yes. Grading above certain volumes, work on slopes and anything near a creek usually needs a permit from the City of Napa or Napa County, sometimes with an engineered plan. Ask the contractor who applies for it and who pays the fees.
How is a grading job estimated?
Contractors look at the volume of earth to move, access for equipment, soil and rock conditions, haul-off distance and compaction requirements. A site visit is normal. Ask for the estimate in writing with those assumptions spelled out.
When is the best time of year for earthwork?
The dry season, roughly May to October, is easiest. Many jurisdictions restrict grading during the rainy season or require erosion-control measures, so book spring and summer work early and ask about winter restrictions.
Who marks underground utilities before digging?
Call 811 or submit a ticket online at least two working days before excavation. Utility companies then mark their lines for free. Private lines, such as a well pipe or a line to a barn, are not marked and should be located separately.
Before you hire
- Ask for the contractor's CSLB licence number and check its classifications and status at cslb.ca.gov
- Ask for proof of liability and workers' compensation insurance before work starts
- Get a written estimate that states volumes, compaction and haul-off assumptions
- Confirm who pulls the grading permit and who calls 811 for utility marking
- Keep the down payment within the California limit of 10 percent or one thousand dollars, whichever is less
