Driveways on Acalanes Ridge

Asphalt paving in Acalanes Ridge is hillside residential work. This small unincorporated neighborhood, formed for the 2010 census from part of Walnut Creek and surrounding land, had 487 homes in 2020, and 86.7 percent of occupied homes were owner-occupied. It is named for the Sacalanes, the Saklan people who lived in the area. Many driveways climb from the street to garages on sloped lots.

County rules

Acalanes Ridge is outside Walnut Creek's city limits. Work in the road right-of-way is permitted by Contra Costa County, whose standard conditions require driveways to slope so stormwater does not run onto the County road and not to interfere with roadside drainage.

Slope and drainage

Runoff from the ridge crosses driveways on its way down. We design cross-slope, berms and drains to control it.

Typical jobs

Replacement of original driveways, edge rebuilds, overlays and sealcoat.

Open space next door

The City of Walnut Creek owns part of the Acalanes Ridge open space. Homes beside it often receive runoff from undeveloped slopes.

Typical Acalanes Ridge projects

With fewer than 500 homes, Acalanes Ridge is a quiet neighborhood where most projects are single-driveway replacements or repairs. The slopes mean runoff and edge erosion are the most frequent problems, followed by cracking from age and sun. On steeper driveways we compact the asphalt in short sections and add sand to sealcoat for traction in wet weather. Households average 2.71 people, and with high owner occupancy, many owners choose a full rebuild with proper drainage rather than another round of patches. Where a driveway has settled near the garage, we regrade so water flows away from the house.
