WHAT TO TAKE AWAY
- Share the actual post and gate layout before root work.
- A boundary is not a blanket authorization to sever roots.
- Utility planning must cover the final digging footprint.
Start with the fence layout
A fence project needs defined corners, gates and post locations, not a broad promise to remove roots along an entire boundary. Share the proposed fence drawing with the person assessing the trees. Mark which locations are fixed and which may be adjusted. Include existing fences, retaining walls and nearby trees in the site photos. If the final layout is still undecided, say so before requesting removal. Clearing first and designing later can disturb more ground than the project ultimately requires.
Resolve the boundary question
A fence line, a mown edge and a tree position do not by themselves establish legal ownership. Confirm the relevant property information and obtain agreement where shared or neighbouring interests are involved. This guide does not decide a neighbour's rights or give permission to cut roots at a boundary. If ownership is unclear, resolve it before commissioning the work. For a possible public tree, Calgary Urban Forestry is an appropriate inquiry route. Give the fence contractor the same ownership information so every trade works from the same assumptions.
Plan for buried lines
Fence holes disturb the ground and require utility planning. Submit an Alberta locate request in advance, allow the utility owners to respond and separately identify customer-owned lines. Utility Safety Partners advises at least three full working days of lead time; the work still depends on completed responses and any utility-owner instructions. Mark the intended digging area accurately so it covers the actual fence footprint. A later change to the gate or corner location may change the area that needs attention. Do not treat a ticket number alone as evidence that the revised project area is clear.
Let the tree assessment influence details
If retained-tree roots conflict with a post location, ask the arborist and fence contractor to consider a layout or construction detail that avoids unnecessary damage. The appropriate choice depends on the tree, site and fence design. A root that is convenient to expose is not automatically safe to remove. Record the agreed approach and specify what happens if an unexpected root appears. Keep the decision with the qualified people responsible for tree assessment and fence construction rather than asking the digging crew to make an on-the-spot biological judgement.
Coordinate work and finishing
Identify the order of removal, fence installation and ground repair. If a stump needs treatment, establish how close equipment can work to the existing fence and whether any panel removal is authorized. Confirm who replaces disturbed surfaces and what happens to debris. Take before-and-after photographs of gates, panels and the route used by machinery. A complete proposal leaves you with an understandable handover to the fence installer. Read living-tree roots and machine access when preparing the quote request.
A practical question to settle
Ask the fence designer which post positions have flexibility and which are fixed by the design. Share that answer with the arborist before ground work. A limited adjustment may resolve a conflict, while moving a post without design review can create a different construction or boundary problem.
