Contra Costa County
Grading & Site Prep in Contra Costa
Shape the dirt right so everything built on it lasts.
Leveling and shaping soil, cutting and filling, building pads, and compacting ground so it drains correctly and supports what comes next — a foundation, a barn, a driveway, or a finished yard. Across Contra Costa County — from Concord, Walnut Creek, Antioch, and Brentwood — in the Diablo foothill towns the work is mostly fire mitigation and defensible space, while out in Brentwood and the East County it's land clearing for farmland and new home sites.

Local context
Why Contra Costa landowners need grading
The grassy Diablo foothills above Lafayette, Orinda, and Danville sit squarely in the wildland-urban interface, and dry-season grass and oak woodland keep defensible-space compliance front of mind for hillside homeowners.

Common questions
Grading & Site Prep FAQs
How much does grading cost?+
It depends entirely on how much earth moves. Operators often bill $100–$300 per hour, or $0.08–$2.00 per square foot. A quarter-acre building pad with cut, fill, and compaction typically runs $4,000–$11,000, while general per-acre site prep ranges from $200 to $6,000. Importing or exporting soil is the biggest swing factor.
Do I need a permit to grade my property?+
Usually yes if you're moving meaningful volumes of soil or altering drainage — most Bay Area counties require a grading permit in those cases. Structural building pads frequently also require engineered plans and a soils report with an engineer's sign-off. Check with your county before starting; thresholds vary.
Why does compaction matter?+
Loosely placed fill settles over time, and settling under a foundation, slab, or driveway causes cracking and failure. Proper grading places fill in thin lifts and compacts each to a specified density so the ground stays put. For anything you're building on, compaction to spec isn't optional.
Can grading fix my drainage problems?+
Very often, yes. Standing water and water running toward a structure are usually grading problems — the ground slopes the wrong way. Re-grading to establish positive drainage away from buildings, sometimes paired with drains or swales, is the standard fix and far cheaper than dealing with foundation or moisture damage later.
Do you need a survey first?+
For a simple yard level, no. For building pads, driveways, or anything tied to a foundation or permit, working from a survey and target elevations is what keeps the job correct and inspectable. If you don't have one, we'll tell you when it's worth getting.
