Danger Tree Removal in Duncan

What makes a tree a hazard

The signs Duncan Tree Removal looks for are a visible lean that has changed, dead or missing bark, fungal growth or cavities at the base, cracked or hanging limbs, and root heave after wind or heavy rain. Douglas fir and western red cedar are the two species most often flagged on Cowichan Valley properties, both listed by name in Duncan's own Tree Protection Bylaw No. 3135.

The Bylaw No. 3135 hazard exemption

Duncan requires a permit to remove a protected tree — 30 centimetres DBH for most species, 20 centimetres for Douglas fir, western red cedar, grand fir and big leaf maple — but the City waives its $50 permit fee once a hazard is confirmed. A refundable replacement-tree security still applies. North Cowichan has no equivalent tree protection bylaw at all, though its Development Permit Areas 3 and 4 (Natural Environment and Hazard Lands) can still restrict removal near the Cowichan River floodplain.

Rigging and drop zone

A hazard tree rarely has a clean fall path — that's usually why it's being removed. Duncan Tree Removal sections the tree down piece by piece with rigging when the drop zone is tight against a house, fence or driveway, and coordinates with BC Hydro's locate line before any work near overhead service lines.

What's included

• Hazard tree assessment

  An ISA Certified Arborist inspects lean, decay and root condition and confirms Bylaw No. 3135 hazard status in writing.

• Rigged and sectional removal

  Piece-by-piece takedown for trees with no clear fall path, using rigging near structures and lines.

The removal process

1. 1

   Free hazard assessment — an ISA Certified Arborist inspects the lean, decay and root condition on-site and confirms whether the tree qualifies for Bylaw No. 3135's hazard-fee waiver.

2. 2

   Written quote — a flat-rate price covering the assessment, the removal method and cleanup, with no hourly surprises.

3. 3

   Permit and locate — Duncan Tree Removal files the Bylaw No. 3135 paperwork where required and calls BC 1 Call before cutting near any service line.

4. 4

   Removal and cleanup — the tree is felled or sectioned down safely, and the site is cleared of debris and wood on the same visit unless the homeowner wants the wood left.

Local conditions

Duncan's Tree Protection Bylaw No. 3135 sets a lower diameter threshold for Douglas fir, western red cedar, grand fir and big leaf maple — 20 centimetres DBH versus 30 centimetres for other species — which means conifers common on Cowichan Valley lots trigger the permit requirement earlier than homeowners expect. Properties along the Cowichan River floodplain, on the city's eastern side, carry an added flood-plain consideration under Duncan's Flood Plain Management Bylaw No. 3236 when root systems near the bank are disturbed.
