Retaining Wall Construction in Coquitlam

The City of Coquitlam requires a building permit for retaining walls over 1.2 metres. Burke Mountain and Westwood Plateau have hillside development permit areas with additional slope, tree, and drainage requirements. Coquitlam has a tree protection bylaw that covers any tree with a DBH over 20 cm on residential lots. Streamside protection zones apply to many lots near Scott Creek, Como Creek, and the Coquitlam River.

Burke Mountain and Westwood Plateau are glacial till with rocky substrate and occasional bedrock exposures. Maillardville, Austin Heights, and Como Lake are silty loam over glacial till, which is better for excavation but with many mature trees that restrict dig zones. River Springs and Scott Creek have creek adjacent considerations. This is why every Trueform retaining Wall Construction project in Coquitlam starts with an onsite soil assessment before we finalize base depth, drainage, and reinforcement.

Coquitlam receives 1,800 to 2,000 mm of annual rainfall, with upland neighborhoods (Burke Mountain, Westwood Plateau) seeing more than the Coquitlam River valley. Winter freeze thaw is more pronounced on Burke Mountain than in Maillardville. Mountain runoff events during atmospheric rivers are significant on upland lots. Our retaining Wall Construction installations are designed for these specific conditions. Drainage capacity, freeze thaw movement, and seasonal load are all factored into the spec for every Coquitlam project.

If your Coquitlam address isn't on this list, we still serve it. Call (604) 217-8966 to confirm.

On Burke Mountain and Westwood Plateau, assume engineering is part of the project, because it almost always is. In older neighborhoods like Maillardville and Austin Heights, plan around the trees, not through them. If you are near any creek in Coquitlam, verify setback requirements before designing.

Retaining wall costs in the Fraser Valley typically range from $35 to $85 per square face foot installed, depending on height, material selection, site access, and whether engineering drawings or permits are required. A standard 3 foot gravity wall in Allan Block will be at the lower end, while a 6 foot geogrid reinforced wall with premium stone facing will be at the upper end. We provide a detailed, transparent estimate after our free onsite consultation. In Coquitlam specifically, the cost driver to watch is the soil and access combination. On Burke Mountain and Westwood Plateau, assume engineering is part of the project, because it almost always is. In older neighborhoods like Maillardville and Austin Heights, plan around the trees, not through them. If you are near any creek in Coquitlam, verify setback requirements before designing. We give you a transparent itemized estimate after the onsite visit so there are no surprises once the retaining Wall Construction build starts.
