Asphalt Paving in Diablo, CA

Asphalt paving in Diablo is small-scale, high-care residential work. Diablo is an unincorporated community 2.5 miles east-northeast of Danville, at about 528 feet, with 455 housing units at the 2020 census and an owner-occupancy rate of 93.9 percent. Its post office opened in 1916. Properties are on hilly ground below Mount Diablo, and driveways tend to be long, landscaped and steep in places.

County rules

Diablo is unincorporated. A Contra Costa County encroachment permit covers any work in the road right-of-way, and the County's conditions require that the driveway's location not create a hazard or nuisance and that removed curb or sidewalk be saw cut and doweled.

Hillside drives

We compact asphalt in short pulls on grades, support downhill edges, and plan drainage at bends and at the garage.

Mature landscaping

Many properties have old trees, stone walls and planted borders right up to the driveway. We protect them during removal and paving and finish edges neatly.

Sealcoat and repair

For driveways in good shape, crack sealing and sealcoat keep them looking new. Where edges have broken or roots have lifted the surface, we rebuild those sections before sealing.

Planning

We walk the drive with you, measure, note drainage and trees, and provide a written estimate.

Typical Diablo projects

Work in Diablo is mostly long-driveway replacement and maintenance on hilly estate lots. Owners often want the driveway to blend with stone walls, old trees and landscaped borders, so we pay close attention to edges and transitions. Many driveways have shoulders that have eroded over years of winter rain; rebuilding and supporting them is often the first step. We also handle drainage under and beside driveways, including culverts at low points and swales along the edges. Diablo's population of about 1,255 and its 424 households mean every project is close to neighbors, so we keep the site clean and the road clear.
