Driveway Work Inside Blackhawk

Asphalt paving in Blackhawk means working within a gated community governed by both Contra Costa County rules and a homeowners association. Blackhawk sits at about 997 feet on the foothills of Mount Diablo. Its first housing phase opened in 1979 after developer Ken Behring bought 6,200 acres in 1975; the plan was scaled back to about 2,400 homes and more than 2,000 acres of open space were offered to Mount Diablo State Park. Many driveways are now 30 or more years old.

HOA approvals and access

Blackhawk's HOA provides 24-hour security, and contractors need gate access arranged in advance. Driveway changes often need HOA design approval. We provide drawings and specs and coordinate access.

County rules

Blackhawk is unincorporated, so County rules apply alongside the HOA's. Contra Costa County issues encroachment permits for work in County road right-of-way and asks for two working days' notice to its inspector before work starts.

Elevation and runoff

At close to 1,000 feet on sloped lots, Blackhawk homes see runoff from the hills above. Drainage design is part of every driveway job.

Typical work

Driveway replacement on first-generation driveways
Motor courts and parking pads
Overlays where the base is sound
Sealcoat and crack sealing

Typical Blackhawk projects

Blackhawk's original homes were built from 1979 into the early 1990s, so many driveways are now 30 to 45 years old. Some have been overlaid once already and are showing cracks again; others have edges that have settled where irrigation keeps the soil wet. We assess whether another overlay makes sense or whether it is time to rebuild. Motor courts, wider entries and added parking are common requests during remodels. The community includes two clubhouses and two 18-hole golf courses, and much of the work is planned around HOA calendars and security procedures. Median home prices topped $2.4 million in 2025, and owners expect careful, clean work.

Blackhawk Questions

Do I need HOA approval for a new driveway in Blackhawk?

Often, yes, for changes to layout or material. We provide what the HOA needs.

How do you get through the gate?

We arrange access with you and security in advance.

My driveway is from the 1980s. Overlay or replace?

If the base is sound, an overlay can work. If it has failed, replacement is better value.

My driveway was overlaid before and is cracking again. What now?

Repeated cracking after an overlay usually means the base has failed. A rebuild of the affected areas is the lasting fix.
