Steep Drives in Wet Mountains
Asphalt paving in Crestline is about water and slope. Crestline sits at about 4,613 feet in the San Bernardino National Forest, with Lake Gregory at its center, and averages about 37.5 inches of precipitation a year, most of it in January and February. That is more than six times what Victorville gets. Runoff pours down steep streets and driveways in winter storms, and freezing nights work that water into every crack.
Mountain lots
Crestline had 11,650 residents and 7,306 housing units at the 2020 census. About 32 percent of units were vacant, many of them second homes and cabins. Lots are often steep and narrow, with short, sloping driveways and retaining walls.
What mountain driveways need
- A base that drains, so water does not sit under the asphalt
- Cross slopes and outlets that direct runoff off the drive
- Tight compaction on slopes so the asphalt does not shove
- Flush transitions to the street for plows and low cars
- Cracks sealed every fall before freezing weather
Part-time owners
With so many second homes, we often schedule work while owners are away, send photos at each stage and leave the drive barricaded until it is ready.
Season
Paving in the mountains happens from late spring to early fall, when ground temperatures let hot asphalt compact. Wet winters mean repairs are best done in summer.
Since 1970
Crestline was first counted in the 1970 census as the unincorporated Crest Forest and became a CDP named Crestline in 1980. Many driveways date back decades and have been patched repeatedly.
Costs
HomeGuide lists standard asphalt driveways at about $5 to $12 per square foot, and some contractors set a $2,000 minimum. Steep access, retaining walls and drainage features add cost. Crack sealing at about $0.50 to $3 per linear foot is the best value maintenance here.
Access
Narrow, winding streets limit truck size. We plan equipment and deliveries during the site visit.
Lake Gregory area
Homes around Lake Gregory see summer visitor traffic. We schedule work for weekdays.
Rebuilding patched drives
Many Crestline drives have been patched for decades. When patches outnumber original pavement, rebuilding the base once is usually the better investment.
Snow and ice
Crestline gets winter snow and frequent freezes. Meltwater runs down steep drives and refreezes at night. Good cross slope, outlets and sealed cracks are the best defense.
Second homes and rentals
With about a third of Crestline's housing units vacant at the 2020 census, many owners are away for long stretches. A fall visit for crack sealing and a spring check for winter damage keeps a driveway in shape without the owner needing to be there.
Owner-occupied homes
Among occupied homes, about 73.8 percent are owner-occupied, and year-round residents often want a drive rebuilt once, properly.
Retaining walls
Many Crestline driveways run alongside or on top of retaining walls. We keep heavy rollers back from the edge of walls and make sure runoff from the new pavement does not pour over or behind them.
County permits
Crestline is unincorporated San Bernardino County. Work in county road right-of-way needs a county encroachment permit. Call (760) 383-7312 or
