Road & Driveway Construction
Road construction and driveway development for hillside properties, rural estates, and commercial sites throughout the Santa Cruz Mountains.
Service Overview
Durable Roads & Driveways Built for California Terrain
Private road construction on mountain properties in the Santa Cruz Mountains is fundamentally different from a flat-lot driveway. The stakes are higher, the challenges are more complex, and the margin for error is much smaller. A poorly graded mountain road will wash out in the first major rain event. A road without proper drainage engineering will erode the slope above it. A road without adequate width or surface preparation becomes a liability in an emergency evacuation.
CStille has been building mountain roads and driveways in the Santa Cruz Mountains for over 30 years. Every road we build incorporates proper drainage culverts, cross-slope drainage, base course selection for local soil conditions, and grade management that holds through California’s increasingly severe winter rain events.

FAQs
Frequently Asked Questions
Common questions about our Land Clearing & Wildfire Mitigation services, process, service areas, and licensing. Have more questions? Give us a call or send us a message.
Do I need a permit to build a private road?
In most cases, yes. Road construction typically triggers grading permit requirements, and properties in fire hazard zones may require CalFire and county approval for access road specifications. CStille works alongside your project engineer to coordinate permits before breaking ground.
How do you prevent erosion on mountain roads?
Cross-drainage culverts, outsloping or insloping the road surface, rock-lined channels, and a base course matched to the local soil — all shaped into the grade as we build, not added after.
How long does it take to build a private road?
A straightforward 500-ft access road on reasonable grades runs about 3-5 days. Longer or steeper roads are scoped after the site visit.
What's the difference between a driveway and a CalFire access road?
A standard driveway is built to vehicle and code requirements for the property. A CalFire access road has to meet specific width, grade, clearance, and turnaround requirements so fire apparatus can actually use it in an emergency — we build to whichever standard your project requires.
Can you widen or improve an existing road instead of building new?
Yes. We regularly widen narrow access roads, improve failing surfaces, and add drainage to roads that were never properly engineered the first time.
