Serving the Cowichan Valley
Excavation and Land Services in Mill Bay
We check depth to rock on your Mill Bay site so you get an accurate estimate for your excavation.
Duncan Excavating handles lot clearing, foundation digging, perimeter drainage and driveway installations across Mill Bay, Shawnigan Lake and the Malahat. Operating in CVRD Electoral Area A, we verify depth to rock on your site where soil cover varies from under 1 metre on Malahat ridges to 60 metres in buried valleys. We provide written quotes after visiting your property.
Ground conditions in Mill Bay change dramatically between neighbouring properties. We visit your lot to check soil depth and access before scheduling machines.
The depth to bedrock on your property drives your final job price. Because breaking rock requires an excavator fitted with a hydraulic breaker at a distinct rate, we evaluate your ground during an initial site visit.
What sits under the soil in Mill Bay?
Provincial mapping shows bedrock less than 1 metre down across much of the Malahat Ridge, while adjacent valley pockets contain loose soil up to 60 metres thick. Because you cannot tell rock depth from the surface, we inspect your property before digging footings and foundations or service lines. Knowing your ground conditions in advance keeps your project on schedule.
Site permits and slope rules in Area A
Mill Bay is located in CVRD Electoral Area A, where roughly 9 per cent of the parcel area sits within the Agricultural Land Reserve. The CVRD building bylaw mandates a permit for constructing or repairing retaining walls, alongside professional engineer certification for fill slopes steeper than 1:2. Working on reserve land requires filing a Notice of Intent with the Agricultural Land Commission prior to soil placement.
How we check the ground before we quote
We walk your lot on foot to evaluate actual site conditions before writing your estimate. Looking at maps alone does not show narrow driveway turns, steep slopes, or buried rock ledges hiding under topsoil.
During the visit, we measure access width to make sure our equipment fits through gates or between trees. We check where surface water drains and look for rock outcrops on neighbouring ground. We also identify where haul trucks can park and turn without blocking traffic. Examining these factors in person allows us to price your project accurately based on real ground conditions rather than guesswork.
What your written quote lists
Your written estimate breaks down every part of the job so you see exactly where your money goes. We list machine time as a distinct line, covering equipment operation on your property.
Trucking is shown separately because moving material depends on haul distance and traffic conditions. Tipping and disposal fees appear as their own item based on the type of spoil removed from your lot, such as clean soil, land-clearing brush, or concrete rubble. Permit fees or material costs like gravel and pipe are also itemized clearly. This open format lets you see how each factor shapes your total cost before any work starts.
