Excavation and Site Prep in Cumberland

Coal country ground

When excavating here, depth to solid rock is the key variable. While Courtenay has deep silt and Comox has deep sand, Cumberland often brings solid rock right up to footing depth.

Rock is quoted by the hour rather than by the project because underground rock volumes cannot be accurately measured from above. We verify property titles and geotechnical reports with the Village of Cumberland to check for old underground coal workings before starting any major digging.

Slope, water and the west side of the valley

Cumberland sits against the rising ground on the west side of the valley, and slope changes every part of an excavation. We manage water runoff during active excavation, as well as after the job is finished. Cut-and-fill balance is harder to get here, and it takes longer to position the machine.

The valley's 1,400 mm of annual rain arrives mostly between October and April, running quickly down Cumberland's sloped lots. Erosion control during clearing and excavation happens as we go — we don't leave it for the end.

The upside is drainage. Where the Courtenay flats need a drain to move water away from a foundation, sloped Cumberland lots often need a properly graded surface and a place for the water to go.

Excavating on tight village lots

The Village of Cumberland administers its own building permits, so neither the City of Courtenay's bylaws nor CVRD Building Services governs work inside village boundaries. Properties on the surrounding slopes outside the village line fall to the CVRD instead.

Same as everywhere else in the valley — check the property tax notice, not the mailing address, to know who's in charge here.

Old village lots and undocumented services

Cumberland's historic townsite features narrow street grids and compact residential lot patterns from early settlement, making equipment access on infill excavation jobs tight. Older lots are narrower, setbacks are tighter, and what is buried under them is less reliably documented than on newer ground.

That makes the BC 1 Call locate more than a formality here. A BC 1 Call utility locate is free, and utility members have three working days to respond. Digging has to start within 14 days of filing the request, and the ticket remains valid for 30 days. Even so, a locate marks registered utility infrastructure, not every abandoned service a century of building has left behind.

On old lots, we locate first, then hand-expose anything uncertain, before the machine touches it. Machine access is the other constraint: a narrow lot with a house already on it often decides the machine class before the soil does.
