Tree Management Plan for Sub-division & Site Servicing - Drawing T-1

1. Pre-construction meeting: Before demolition or site servicing begins, the contractor shall meet with the arborist to review the placement of fencing and other tree protection measures within this plan. a) The Project Arborist shall clearly mark the boundaries of all areas to be fenced and protected. b) Access routes and areas for trade parking and materials storage will be identified with the contractor.
2. Tree Fencing: a) Tree protection fencing shall be installed to the Town of View Royal standards at the locations indicated on this drawing prior to demolition or site servicing permits being issued (see fencing detail on plan). b) Tree protection fencing and armouring shall be maintained in good condition throughout the duration of the project. c) Requests to temporarily remove or move tree fencing must be reviewed by the project arborist for approval.
3. Tree Management Plan posting: a) A full-sized weather-proof copy of this tree plan shall be posted in plain sight in the site office. b) The general contractor shall ensure that all relevant sub-trades are familiar with the drawing and tree protection measures.
4. Site servicing and excavations: The project arborist shall be present to oversee excavation, service trenching, stump removal, site grading or blasting within, or adjacent to, the tree protection areas (TPAs).
5. Root & branch pruning and protection: a) Any tree roots or branches damaged during site work shall be pruned back to undamaged tissue by the arborist. b) The vertical face of excavated cuts adjacent to the TPAs shall be securely covered with non-permeable fabric by the project arborist to prevent soil desiccation and erosion.
6. Mulch & Irrigation: Trees impacted by excavation for site servicing shall be top-dressed throughout their protected root zones with 100mm of clean tree-chip mulch and irrigated once every two weeks during the dry summer period (May to mid-October) to a minimum effective depth of 30cm.
7. Temporary access: If temporary access is required within a tree protection area (TPA), the contractor shall notify the project arborist in advance and review the access requirements and any additional protective measures prescribed by the arborist.
8. Soil armouring: If it is not possible to fence the entire PRZ, the unprotected portion of the PRZ shall be armoured with 3/4" plywood or a temporary cover of geo-textile and 200mm of road-base, moderately compacted with a plate compactor. (See drawing for recommended soil armouring locations.)
9. Storage restrictions: No equipment, materials or excavated soil shall be placed or stored within the TPA.
10. Procedure for rock removal near tree root zones: a) The general contractor will convene a meeting with the arborist and blasting contractor prior to drilling to develop a work plan that minimizes rock removal impacts to protected trees. b) Where considered necessary by the arborist, alternate rock removal techniques, such as hoe-ramming, shall be used in place of blasting. c) Blasting vibrations in the vicinity of the Tree Protection Areas are not to exceed a measured peak particle velocity of 25 mm/sec. i) Seismometer records will be kept of all blasting within a 30m radius of any tree protection areas for review by the project arborist. ii) Seismometers shall be placed at the outer boundary of the tree protection area closest to the blast zone. d) Use DYNAMITE as the explosive product. No fertilizer-based explosive is permitted, due to its toxicity to tree roots. e) The contractor shall prevent rock debris from the blast site from entering the TPA.

Tree Protection Fencing Detail

Modular steel panel fencing is recommended in order to reduce land-fill waste post-construction. Fencing panels shall be secured to the ground with rebar wired to panel frame.

16 x 24” all-weather signage will be attached with the following wording:

• For protected trees: DO NOT ENTER – Tree Protection Zone
• For replacement/landscape tree planting sites: DO NOT ENTER – Future Tree Planting Zone

In cases where steel-panel fencing is not practical or available, fencing shall be constructed with a wooden 2x4 frame (side, top and bottom rails) and back-bracing supports as required to ensure robust placement. Snow-fencing will then be affixed to the frame using battens, zip-ties, staples, wire or nails.
