Project Spotlight: Driveway Grading on Fisher Road. We recently helped a homeowner near Fisher Road whose steep driveway was washing out during heavy rains. We regraded the slope and installed new culverts to manage the runoff. The result was a durable, accessible driveway that handles Cowichan winters without erosion.

Q: Do I need a permit for excavation in Cobble Hill?
A: Large excavation projects in the CVRD often require permits, especially near riparian areas like Shawnigan Lake or sensitive soil zones. We can help guide you through the local permit process.
​
Q: How do you handle the rocky soil in Cobble Hill?
