Tree Protection Measures
Canopy Clearance Pruning
- Douglas-fir 491 holding roots 1 and 2 project into front of property.
- CJF recommends 2.5m canopy lift from current ground for safety and maintenance prune.
- All pruning to ANSI A300 standards.
- Grand Fir 494 CJF advises white tree safety and maintenance prune.
Tree Protection Barriers
- Barriers must be in place prior to any construction activity.
- Prohibit parking and approval permission of selected tree service contractor.
- Maintain fences in good condition until landscape phase.
- No loading dock.
- No pruning above 50% of tree height.
- No materials, fuel, equipment or debris stored within fenced zone.
- No site signs or water within zone.
- Construction of well-braced 1.2m or 2.4m tall wood / snow fence panel tree protection barrier around Tree Protection Zones (TPZ).
- Maintain tree protection fence in good functioning condition until landscape changes are finished and only removed with CJF permission.
- Construction material / waste / concrete outwash must not be placed against / stored within fence boundaries.
- No grade changes (excavation or fill) within fenced zones.
Temporary Machine / Materials Access
- Location must be approved by CJF and prior to installation.
- Temporary woodchip path / fill slope required between access to lower area.
- Machine / materials access must be limited to within woodchip / plywood / access route.
Soil Compaction Protection
- Woodchip paths on plywood base required for access routes above and bottom north property line stairs.
- 15-20cm thickness woodchip over non-woven geotextile (Texel 35c or similar product).
Excavation
- Working within project area, use smallest rubber tracked excavator suitable for job.
- All excavation within tree protection zones must be supervised by CJF.
- Do not allow excavator to climb/descend slope over Douglas-fir 491 35cm surface holding root 1 & 2.
- Pruning of roots >2.5cm diameter must be done by hand.
- In the following locations hand machine excavation with hand:
- Lower property line between waterline and Grand fir 494.
- South property line within Bigleaf maple 495 8.1m PRZ.
- 1.5m either side of Douglas-fir 491 35cm surface holding root 1 & 2.
- Prune excavation exposed roots >2.5cm diameter.
- Hand prune exposed roots >2.5cm diameter severed or damaged beyond reasonable repair by machine/manual tools.
- Hand prune with hand power tools.
CJF Project responsibilities:
- Discuss canopy pruning goals / practice with tree service contractor prior to commencement.
- Layout protection fence alignment with builder at site.
- Consult on temporary machine / materials access slope design / location.
- Supervise woodchip soil compaction protection with contractor.
- Oversee temporary machine / materials access slope construction.
- Oversee excavation along:
- Lower property line between waterline and Grand fir 494.
- South property line within Bigleaf maple 495 8.1m PRZ.
- 1.5m either side of Douglas-fir 491 35cm surface holding root 1.
- Prune excavation exposed roots >2.5cm diameter.
- Consult on location of plantable walls where these encroach toward Douglas-fir 491 35cm surface holding root 1.
- Remain available to other consultants, home owner and builder as requested.
- Occasionally visit site to ensure tree protection measures remain in place.
- Submit summary report at completion of project compaction / Bylaw 1069, 2022 protected tree impact assessment report.
