Tree Protection Bylaw 7671 sets the protected area around a tree’s roots at 10 times the trunk’s diameter at breast height (DBH). That’s the only 10x root-protection formula anywhere in Metro Vancouver.
The Protected Root Area Runs Ten Times the Trunk
Under Bylaw 7671, the protected area around a tree’s roots equals 10 x DBH before any adjustment. A certified arborist can then modify it for the site and the species growing there.
DBH has a specific measuring point: 1.3 m up the trunk, on the uphill side. Multi-stem trees get their own formula. The bylaw takes the largest stem at 100% and adds 60% of each additional stem, up to a maximum of 6 stems counted. Each measurement rounds up to the nearest centimetre.
Two Tree Classes Decide Whether You Need a Permit
Bylaw 7671, consolidated with Bylaws 7960, 8271, 8559 and 8583, protects trees two different ways.
The first is size alone. A “large-diameter tree” is one above a set DBH that isn’t already covered by the second class. Confirm the size with the District of North Vancouver.
The second class, “protected tree,” carries no diameter floor at all. A tree qualifies at any size if it sits on District land, in a protected streamside area, on a steep slope over 20 degrees or 36%, in a wetland or within the 30 m waterfront zone, or inside the Natural Environment, Streamside Protection or Slope Hazard development permit areas. Replacement, covenant, heritage, wildlife and old-growth trees qualify too. So do six named species, regardless of diameter: Arbutus, Garry Oak, Oregon Ash, Pacific Yew, Western White Pine and Yellow-cedar.
A small Pacific Yew a few centimetres across falls under the bylaw the same way a large-diameter tree does.
The Barrier Sits at the Protected Root Area’s Outer Edge
Once the protected root area is calculated, the protection barrier goes up at its outside boundary. The fencing carries “Tree Protection Zone” signage, and the District’s Environmental Protection Officer inspects it before any work starts on site. Failures are ticketable at $300 each.
What the Permit Costs
The Fees and Charges Bylaw 6481 sets the numbers. For protected trees specifically, five or more costs $581. A development removing 10 or more protected trees on a parcel over 1 ha pays $2,908. Confirm the fee for up to 4 trees with the District of North Vancouver.
Large-diameter trees are priced per tree and split by action: $581 per tree to remove, and a separate fee to cut. Do the work before the permit is in hand, and the retroactive permit doubles every fee above.
There’s also an Environmental Compensation Fee, separate from the permit fee itself. It runs a set amount per large-diameter tree, rising if the tree is a Douglas fir or western red cedar. Confirm the amounts with the District of North Vancouver.
Replacement Trees Depend on Lot Canopy
For a large-diameter tree, section 21 starts with the canopy left after removal. Replacement is required only if that canopy cover will fall below 20%. If it will not, this rule requires no replacements.
Below 20%, lot size decides the count. A lot under 420 m² owes 1 replacement tree per large-diameter tree removed. A lot of 420 m² or more owes 3.
The penalty for an unlawful removal stacks: the replacements the bylaw already requires, plus at least 2 more trees, plus 250% of the Ecological Compensation Fee.
Security and How to Apply
Before work starts, the District holds security equal to 125% of the estimated cost of the work.
Applications run through a paper form, available from the District’s tree permit page. Planning, Properties and Permits handles the file at building@dnv.org. Confirm processing times with the District of North Vancouver.

If the removal ground is a hazardous or high-risk tree, ask us first. Some Metro Vancouver bylaws require a report author who also holds the ISA Tree Risk Assessment Qualification.
Reports for District of North Vancouver Permits
Get the 10x figure wrong, and the barrier goes up in the wrong place. Then somebody has to move fencing after the site is already active. The Arborist Group prepares ISA Certified Arborist reports for tree permit applications in Metro Vancouver. Our construction arborist reports cover tree protection for building projects, and we confirm availability for your address before we quote. Contact us with the address to start.
