Introduction
Treescape Consulting was instructed by Brook Mcllroy, 200-161 Spadina Ave, Toronto, Ontario, to undertake a Tree Planning and Preservation Report on trees, larger shrub masses and hedges within and adjacent the boundaries of the proposed Tremt Research & Innovation Park development site located on Pioneer Road in Peterborough, Ontario. The work plan for the tree inventory and preservation plan included the following:
Utilize site plans provided by the client
Assess the physiological and structural condition of the trees as compartments and/or any individual trees as appropriate.
Record the assessment in the form of a written report identifying the surveyed tree compartments and/or individual trees on the supplied plan
Make recommendations to remove and/or retain any trees or tree compartments within the context of approved site development.
The schedule below includes the assessment of trees along the whole entire 85 acres parcel and adjacent naturalized areas to the west identified as above as numbered compartments and individual significant tree . The appended plan TC255-01 identifies the locations of the individual trees and tree compartments. Plan TC255-02 shows removals and tree protection to be read in conjunction with Table 2 below.
As per the City of Peterborough's Unit Price Supplemental Information General Conditions for the protection of trees and shrubs, the specifications for tree protection zones and barrier fencing is as detailed in Appendix 1 (OPSS 801.07.02). Supporting Documents

Limitations of Assessment At the time of inspection, the boundary of the land forming the proposed development site was not staked or identified on the ground and thus it was difficult to determine the boundary of the area. The assessments of the trees summarized in this report were made using accepted arboricultural techniques. These included a visual examination of all the above ground parts of the trees for structural defects, scars, external indications of decay such as fungal fruiting bodies, evidence of attack by insects, discoloured foliage (if in leaf), the condition of any visible root structures, the degree and direction of lean (if any), the general condition of the trees and the surrounding site, the proximity of property and people and the frequency of use. Except where specifically noted, the trees were not cored, probed or climbed and there was no detailed inspection of the root crowns involving excavations. Notwithstanding the recommendations and conclusions made in this report, it must be recognized that trees are living organisms, and their health and vigour constantly change over time. They are not immune to site changes or seasonal variations in the weather conditions. Although every effort has been made to ensure that the assessments were accurate, the trees must be re-assessed periodically. The summary of the assessments presented in this report were valid at the time of inspection.

Existing Site Conditions The proposed TRIP development site is an 85 acre parcel of land located in the northeast corner of Peterborough on the north side of Pioneer Road between the eastern boundary of Trent University's East Bank campus and Douro 9th Line. The entire proposed development site is situated on four large plots of agricultural land. The entire area is bordered by, and subdivided by a combination of hedgerows, naturalized areas and small groupings of individual specimen trees. Tree resources within and adjacent to the development area include:
Southwest boundary along Pioneer Road - large row of middle mature Eastern White Cedars (since removed). Remaining boundaries to the east and north comprise of large farm hedgerows containing mixed species of primarily
mature hardwoods with an under-storey of smaller tree and shrub species. The four farm fields are divided by 3 large farm hedgerows containing mixed species of primarily mature hardwoods with
an under-storey of smaller tree and shrub species. The area to the west of the development area abuts a low lying and wet naturalized area with a concentration of
coniferous trees to the south and a mix of hardwoods in the central and northern portions of the area. The entire area has an under-storey of smaller tree and shrub species.
The initial survey began in mid December 2016. At that time, preparations for the reconstruction of Pioneer Road had begun with the removal of trees along both sides of the right of way which included nearly all vegetation along the south boundary of the development area (Eastern White Cedars).
Proposed Development The development of the Trent Research & Innovation Park will include an array of construction including, but not limited to;
construction of roads and related right-of-way infrastructure
construction of storm water ponds
extension of sanitary and other related services to individual lots
construction of a network of walking trails and paths
development of individual tenant sites This work has the potential to impact significantly upon the above and below ground parts of adjacent trees, hedges and larger shrub masses. As part of the design process an inventory and assessment has been undertaken of all significant trees, hedgerows and larger shrub masses that have above and below ground parts likely to be affected by the proposed works. The inventory is detailed in Table 1 (found below) which includes a key to terms used that may be supported and explained further by information in the appendices. The inventory was carried out in accord with the requirements set out by the City of Peterborough.
Results The results of the tree assessment are reproduced in Table 1 below. The detail includes the predominant species, upper and lower diameter range, average diameter at breast height (1.4m), approximate numbers of significant trees and overall condition (structural and physiological). The assessment includes all trees and compartments of trees within the development area. Table 2 identifies the development impacts upon the assessed compartments and makes recommendations for management within the context of development.

Development Impacts
Table 2
Compartment (CPT) / Tree #
Development Impact Recommendation
Tree # 1750 1. Limits of excavation for the construction of Street E ROW (including primary trail) may encroach onto the southern edge of the tree's dripline.
Provide TPZ fencing as specified. Grading along this section of Street E is unknown. If grade change is similar to the south end of Street D (+1.2m), the tree may need to be removed.
CPT 2 1. Limits of excavation for the construction of Easement B (including primary trail) may encroach onto the eastern edge of the compartment. Removal and/or pruning of some trees may be necessary.
Affected trees are undesirable species overall with American Elm mixed throughout. Many areas along this edge consist of various species of Willow bushes.
Remove and/or prune trees as necessary for development. Where necessary, provide TPZ fencing along dripline of remaining retained trees adjacent to the construction (preferably to the edge of construction/grading limits).
CPT 3 1. Limits of excavation for the construction of Street D ROW (including primary trail) encroaches onto the eastern edge of the compartment. Removal and/or pruning of some trees may be necessary.
2. Limits of excavation for the construction of Street E ROW (including primary trail) will run directly through the southern edge of the compartment. Removal and/or pruning of some trees is required.
Affected trees are undesirable species overall with American Elm and White Cedar mixed throughout.
Remove and/or prune trees as necessary for development. Significant grade change in proposed, ensure that adequate clearance is attained to accommodate the limits of final grading. Where necessary, provide TPZ fencing along dripline of remaining retained trees adjacent to the construction (preferably to the edge of construction/grading limits).
CPT 4 1. Construction of Street D ROW (west end of CPT) and Street A ROW (east end of CPT) encroaches onto the respective sides of the compartment. Removal of some trees is required.
2. Construction of secondary trail may encroach the southern edge of the CPT from the far west to where it crosses through the CPT and continues to encroach the northern edge from this point to the east end of the CPT. Removal and/or pruning of some trees may be necessary.
Affected trees are predominantly large Basswood clusters with an understory of undesirable species and invasive Buckthorn and grapevine.
Remove and/or prune trees as necessary for development. Provide TPZ fencing along dripline of remaining retained trees (especially Tree # 1754) adjacent to the construction (preferably to the edge of construction/grading limits).
CPT 5 1. Construction of Street A ROW will run directly through majority of the compartment starting at the south end of the CPT. The proximity of ROW construction and grading encroaches on the root systems of the remaining trees.
Affected trees include #1760-1773 with an understory of undesirable species and invasive Buckthorn and grapevine.
Remove trees as necessary for development.
CPT 7 1. Construction of service corridor (including primary trail) encroaches onto the eastern edge of the compartment and requires the removal of some trees.
Affected trees are predominantly middle mature Sugar Maples in good overall condition.
Consider connecting the southern end of easement with Pioneer Road through a section of CPT that does not include Sugar Maples.
Remove trees as necessary for development. Provide TPZ fencing along dripline of remaining retained trees adjacent to the construction (preferably to the edge of construction/grading limits).
CPT 8 1. Construction of service corridor (including primary trail) encroaches onto the western edge of the compartment and requires the removal of some trees.
Affected trees are undesirable low land trees overall.
Remove trees as necessary for development. Provide TPZ fencing along dripline of remaining retained trees adjacent to the construction (preferably to the edge of construction/grading limits).
Page 20
Treescape Certified Arborists (TC255-01)
CPT 9 1. Construction of service corridor (including primary trail) encroaches onto the western edge of the compartment and requires the removal of some trees.
Affected trees are primarily Ash and other undesirable low land species.
Remove trees as necessary for development. Provide TPZ fencing along dripline of remaining retained trees adjacent to the construction (preferably to the edge of construction/grading limits).
CPT 10 1. Construction of Street A ROW encroaches onto the western edge of the compartment and requires the removal of some trees.
2. Limits of excavation for the construction of storm water amenity may encroach onto the eastern edge of the compartment. Removal and/or pruning of some trees may be necessary."
3. Construction of secondary trail may encroach the northern edge of the compartment and cuts through the east end of CPT jeopardizing an early mature Sugar Maple (#1708) in good condition . Removal and/or pruning of some trees will be necessary.
Affected trees include 1708-1712 with an understory of undesirable species and invasive Buckthorn.
Remove and/or prune trees as necessary for development. Provide TPZ fencing along dripline of remaining retained trees adjacent to the construction (preferably to the edge of construction/grading limits).
(#3) Consider routing the secondary trail through the CPT between Sugar Maple trees #1709 and 1710. Trail is narrow and low impact, therefore it can encroach the dripline of these trees if necessary.
Trees #1723 & 1724
1. Trees are in direct conflict with construction of storm water amenity and will have to be removed.
Affected trees are poor quality trees growing from rock pile in field.
Remove trees as necessary for development.
CPT 11 1. Construction of primary trail may encroach the western edge of the compartment. Removal and/or pruning of some trees may be necessary.
Affect trees are a cluster of Ash trees on TRIP lands and possibly Willow bushes on adjacent land.
Remove and/or prune trees as necessary for development.
Tree # 1725-1727 1. Poor quality and undesirable trees in conflict with various elements of the development.
Remove trees as necessary for development.
CPT 12 1. Construction of Street A ROW will run directly through the south central section of the compartment and require the removal of some trees.
2. Construction of primary trail may encroach the western edge of the compartment. Removal and/or pruning of some trees may be necessary.
Affected trees are undesirable and smaller Basswood, White Cedar and invasive Buckthorn.
Remove and/or prune trees as necessary for development. Provide TPZ fencing along dripline of remaining retained trees adjacent to the construction (preferably to the edge of construction/grading limits).

Summary The assessment at the Trent Research & Innovation site was carried out on the tree resources located on and adjacent to all boundaries of the site. Together with an inventory of trees in accord with the draft condition, the assessment sought to identify the significant trees that;
Have a safe useful life expectancy that justifies their retention, and any design changes and costs associated with that; i.e. extend into the future for an acceptable period in the design life of the intended development,
Are likely to survive the construction process,
Are likely to survive within any changed growth environment and,
Are compatible with, and sustainable within the context of new development. The tree resources identified in this report are located within former agricultural hedgerows (fence lines). They comprise mainly of volunteer, planted trees and possibly the remnants of original tree cover prior to clearance for agricultural use. The fence lines also contain many rocks moved from the open fields during the years of agricultural use. Previous management is only likely to have comprised of removal of dead and fallen trees with, perhaps, some removal of trees for firewood during agricultural use. This historic management has resulted in numerous standing dead trees and tree resources which are only of moderate structural condition (many trees have poor structure at the base due to growth restriction by large rocks), but nevertheless are worthy of retention within the context of development. That being said, it is recommended that dead, dying, damaged and hazardous trees be tended to as the development proceeds around these hedgerows and naturalized areas. Ongoing efforts should be taken to replant native species trees in and around these areas as trees are removed. It is also worth noting that the previous agricultural use (ploughing) will have effectively pruned the roots of trees growing into the site and this will limit the damage from adjacent development. The master plan for this development strives to retain a high percentage of hedgerows and naturalized areas while maximizing the available area to be developed. As such, all tree compartments bordering and within the site require varying levels of tree removals and protection to accommodate street right of ways, trails and other infrastructure. The largest impact of development is the complete removal of CPT 5 to accommodate Street A ROW. The majority of the site will be maintaining natural grade. This combined with maintaining the proposed natural feature lot lines provides automatic protection of tree resources during the development of individual subdivision lots because construction and grading limits will not be encroaching bordering tree lines.

Tree Preservation
Pre-construction (of each development phase)
Prior to any construction work, establishment of storage compounds, site offices, latrines, contractor parking or storage of any materials; all approved tree works shall be undertaken in accord with the recommendations detailed in both the tree inventory and development impact summary in accord with the current ISA Best Management Practice –Tree Pruning (companion publication to ANSI standard A300 Part 1 (2008) Tree, Shrub and other Woody Plant Management –Standard Practices, Pruning). Following this, all trees identified for retention within the schedule (Table 2) shall be protected using appropriate tree protection methods such as barriers installed in the locations identified on the plans TC255-02 to create tree protection zones (Subject to revision as required by final design). Where this is not possible, trunk/lower branch protection and/or soil and root protection within the TPZ shall be as detailed below. Other precautions such as tying back branches, modification of construction techniques, thrust boring and the use of special surfaces may be required as necessary.
Tree Protection Zone (TPZ) and Barriers (refer to Appendix 1 for OPS drawings)
Barriers for tree protection shall be a minimum height of 1.2 m consisting of material approved by the Contract Administrator, supported by steel posts. The number of steel posts shall be enough to keep the material from sagging and the fence erect. The barriers shall be erected at the dripline of trees or woodlot edges within the Working Area, prior to commencement of construction operations at locations specified in the Contract Documents. Where a clearance zone of 1.5 m cannot be established between the barrier at the dripline and the limit of grading, the barrier may be placed within the dripline, subject to the approval of the Contract Administrator. When the barrier is placed within the dripline,
a) a minimum distance of 0.75 m shall be maintained between the trunk of the tree and the barrier, and b) a distance of 1.5 m shall be maintained between the barrier and the limit of grading.
When the trunks of trees are less than 4.5 m apart, the trees shall be considered a woodlot and the barrier shall be placed so it forms a continuous barricade around the woodlot as specified in the Contract Documents.
A barrier is not required where an existing fence serves the same purpose. At such locations, the barrier shall terminate at the existing fence so that a continuous barricade is provided between the trees and the area of work.
The barriers shall be maintained erect and in good repair throughout the duration of construction operations without breaks and unsupported sections and shall be removed upon completion of the work.
TPZ Signage
All sections of fencing should be clearly marked with signs stating that the area within is a Tree Protection Zone and that no one is allowed to disturb this area. Signs should contain contact information for the contractor and/or the Arborist and clearly state any consequences that are associated with violations. Text on the signs should be on all languages commonly spoken on the site.

Soil and Root Protection Within the TPZ
“If traffic cannot be kept outside of the TPZ for the entire duration of construction, actions can be taken to disperse the vehicular load and protect roots, minimizing soil compaction and mechanical root damage. These include:
Applying 15-30cm (6-12”) of wood chip mulch to the area
Laying 2cm (¾”) thick plywood or 10 x 10cm (4x4”) wood beams over a 10+ cm (4+ “) thick layer of wood chip mulch
Applying 10-15cm (4-6”) of gravel over a taut, staked geotextile fabric; or
Placing commercial logging or road mats on top of a mulch layer
Stone, geotextile and mulch exceeding 10cm (4”) thick will need to be removed from the TPZ once the threat of soil or root damage has passed.”
Trunk Protection
“When trees are so close to construction activities that the trunk or buttress roots may be mechanically damaged, those parts should be protected. This can be done by installing 5cm (2”) thick wood planks, such as 5x10cm or 5x15cm (2x4”s or 2x6”s) around the trunk, preferably on a closed-cell foam pad. Straps or wire are used to bind the planks in place. No fasteners should be driven into the tree. Trunk protection should be adjusted to allow growth if it is in place during periods of trunk diameter growth.”

During construction
Throughout the construction an ISA Certified Arborist shall be retained for the following:
Advise and oversee any site activities where construction impacts upon retained trees.
Advise on root severance and pruning.
Advise on tree damage caused by, or occurring during construction, including storm events, and specify and detail remediation methods.
Advise on location of boring and excavation methods in the root zone of trees where appropriate.
Advise on grade changes within the critical root zone of trees.
Monitor tree health and advise on cultural requirement of trees during construction.
Advise on any unforeseen changes to construction that are likely to be detrimental to retained trees.
Monitor the Tree Protection Zone (TPZ) barriers and TPZ signage.
Supervise the removal/dismantling of all the approved tree protection systems at the completion of construction.
Post-Construction Care
Following the completion of construction and the removal of all tree protection, the Arborist will re-inspect all retained trees and assess their current health and vitality. The Arborist will advise on the requirement for irrigation, deep-root fertilizing and de-compaction, as appropriate to ensure the continued health and sustainability of the retained trees.
