1. Introduction

Maintenance, growth and enhancement of the urban forest are important goals of the City of Toronto. Preserving and protecting healthy trees can help the City to achieve these goals. Considering tree protection in the initial stages of construction planning may mean the difference between preserving a healthy tree and having to remove it. Plans created with tree protection in mind help protect the city's urban forest.

The tree protection policy and specifications outlined below reflect the policy of Toronto City Council. Anyone failing to adhere to the tree protection policy and specifications will be financially responsible for any resulting damage to trees and may be charged under the provisions of the applicable City of Toronto tree by-law or subject to orders to comply.

Prior to commencing with any demolition or construction activity it is important that an arborist1 determines the location, species, size and condition of trees on the property and surrounding properties and becomes familiar with the tree protection by-laws that could impact the proposal.

The following by-laws protect trees in the City of Toronto:

• Street Tree By-law, City of Toronto Municipal Code Chapter 813, Article II, protects alltrees situated on City streets.

• Private Tree By-law, Article III, Chapter 813 of the City of Toronto Municipal Codeprotects trees on private property with diameter of 30cm or more and trees of anydiameter that were planted as a condition of a permit issued under this bylaw or a siteplan agreement.

• The Ravine & Natural Feature Protection By-law, Chapter 658 of the City of TorontoMunicipal Code prohibits and regulates the injury and destruction of trees, as well asfilling, grading and dumping within designated areas of the City. There is no minimumdiameter for a tree to qualify for protection under the Ravine and Natural FeatureProtection By-law. Trees of any size located in the designated areas qualify forprotection.

• The Parks By-law, Municipal Code Chapter 608, Article VII protects all trees located ina City park.

All above noted by-laws are implemented by Urban Forestry under the authority of the General Manager, Parks, Forestry and Recreation. City of Toronto's tree protection by-laws can be found at www.toronto.ca/trees.

Types of Tree Damage

Physical injury to the trunk, crown and roots of a tree will occur if construction equipment is permitted close to trees or if structures are built into the growing space of a tree. Inappropriate pruning may also result in tree injury. Physical injuries are permanent and can be fatal.

1 Arborist – An expert in the care and maintenance of trees including an arborist qualified by the Ontario Training and Adjustment Board Apprenticeship and Client Services Branch, a certified arborist qualified by the International Society of Arboriculture, a consulting arborist registered with the American Society of Consulting Arborists, a registered professional forester or a person with other similar qualifications as approved by the General Manager, Parks, Forestry and Recreation.

http://www.toronto.ca/trees

Root cutting is another type of physical injury that can significantly impact the health of a tree. The majority of tree roots are found in the upper 30 to 60 cm of soil. Excavation for foundations or utility installation may cut roots if the excavation is too close to trees. Trees can become destabilized and may fall over if anchor roots are severed.

Compaction of the soil in the tree root zone is one of the leading causes of tree decline in Toronto’s urban forest. Soil compaction occurs primarily from vehicles and equipment moving across the root zones. Piling or storing materials or debris on top of the root system can also result in soil compaction. Soil compaction causes the pore spaces in the soil, which contains air and water necessary for root growth, to be reduced. Without space available for oxygen and water, tree roots will suffocate and tree decline will follow. With rutting, a form of intense compaction, roots are severed by the tires of equipment. Root destruction can also be caused by changes to the existing grade. Adding soil on top of tree roots can smother them by reducing the amount of oxygen and water they can receive. Only a few centimetres of added soil can have a detrimental impact on tree health.

The structural elements of a tree in an optimal growing environment are shown on Figure 1. This figure illustrates the terms used in this policy.

2. Protecting Trees

There are a number of steps that can be taken to protect trees prior to, during and after any construction project. Hiring an arborist should be the first step. An arborist can advise on current tree maintenance requirements and determine the impact the proposal will have on trees and the surrounding natural environment.

An inventory of trees on subject and adjacent properties that may be impacted by the proposed work should be prepared in accordance with the City tree by-laws so that the project can be designed with tree protection in mind. A tree protection plan prepared by an arborist will identify the location, species, size and condition of all trees within the area of consideration, identify the extent of injury where applicable and outline proposed tree protection measures for the trees identified for protection.

The area of consideration for trees protected under the Private Tree By-law (Municipal Code, Chapter 813, Article III) includes the entire area of site disturbance, including construction related traffic and material storage, and extends 6m beyond the limit of site disturbance. For trees protected under Ravine and Natural Feature Protection By-law (Municipal Code, Chapter 658), the area of consideration includes the area of site disturbance and 12m area beyond.

The following chart provides the required distances for determining a minimum tree protection zone (TPZ) for trees located on a City street, in parks and on private property subject to Private Tree By-law and for trees located in areas regulated under the Ravine and Natural Feature Protection By-law. The minimum tree protection zones are based on the diameter of the tree. While these guidelines provide minimum protection distances for the anchor and transport roots of a tree, there can still be significant loss of the feeder roots beyond the established tree protection zone. Feeder roots are responsible for water and nutrient absorption and gas exchange. For this reason, Urban Forestry may require a TPZ larger than the minimum, depending on the tree and the surrounding environment.

The diagram below shows how the TPZ is determined:

Figure 2: Minimum Tree Protection Zone (TPZ) Determination

In some cases, disturbances in the TPZ may be unavoidable, in which case, the TPZ must be adjusted in consultation with the arborist and Urban Forestry. In these situations, it may be necessary to implement other tree protection measures such as horizontal root protection as noted in section 3 of this document.

In addition to establishing and creating tree protection zones, it may be necessary to implement other protective measures, such as adding mulch to the root zone, aeration of the soil, pruning for deadwood or removing limbs that may be impacted by construction activity. This is also the time to determine the location where new trees can be planted to compliment the construction project and help with the renewal and growth of the urban forest.

Prior to commencing with any excavation, roots approved for pruning by Urban Forestry must first be exposed using pneumatic (air) excavation, by hand digging or by using a low pressure hydraulic (water) excavation. This exploratory excavation must be undertaken by an experienced operator under the supervision of a qualified and experienced arborist. The water pressure for hydraulic excavation must be low enough that root bark is not damaged or

July 2016 7

removed. This will allow a proper pruning cut and minimize tearing of the roots. The arborist retained to carry out root pruning must contact Urban Forestry no less than three (3) working days prior to conducting any specified work.

Exploratory excavation may also be required for open face cuts outside the minimum tree protection zone (TPZ).

Communication between owners and their designated agents, arborists, contractors and sub-contractors throughout the construction process is critical to ensure that everyone involved is aware of the issues surrounding tree protection, and fully understands the tree protection methodology. Construction damage to trees is often irreversible.

Prohibited Activities Within a TPZ

Except where authorized by Urban Forestry, any activity which could result in injury or destruction of a protected tree or natural feature, or alteration of grade within a Ravine and Natural Feature Protection (RNFP) area, is prohibited within a TPZ, including, but not limited to, any of the following examples:

• demolition, construction, replacement or alteration of permanent or temporary buildings orstructures, parking pads, driveways, sidewalks, walkways, paths, trails, dog runs, pools,retaining walls, patios, decks, terraces, sheds or raised gardens

• installation of large stones or boulders• altering grade by adding or removing soil or fill, excavating, trenching, topsoil or fill scraping,

compacting soil or fill, dumping or disturbance of any kind• storage of construction materials, equipment, wood, branches, leaves, soil or fill,

construction waste or debris of any sort• application, discharge or disposal of any substance or chemical that may adversely affect

the health of a tree e.g. concrete sluice, gas, oil, paint, pool water or backwash water from aswimming pool

• causing or allowing water or discharge, to flow over slopes or through natural areas• access, parking or movement of vehicles, equipment or pedestrians• cutting, breaking, tearing, crushing, exposing or stripping tree's roots, trunk and branches.• nailing or stapling into a tree, including attachment of fences, electrical wires or signs• stringing of cables or installing lights on trees• soil remediation, removal of contaminated fill• excavating for directional or micro-tunnelling and boring entering shafts

The above mentioned prohibitions are for area(s) designated as a TPZ. If possible, these prohibitions should also be implemented outside the TPZ in areas where tree roots are located. The roots of a tree can extend from the trunk to approximately 2-3 times the distance of the dripline.

3. Tree and Site Protection Measures

The following are examples of specific tree and site protection measures that may be required by Urban Forestry:

• Plywood tree protection hoarding (minimum 19mm or ¾"), or equivalent barriers, asapproved by Urban Forestry, shall be installed in locations as detailed in an Urban Forestryapproved Tree Protection Plan. Tree protection barriers must be made of 2.4m (8ft) highplywood hoarding or equivalent as approved by Urban Forestry. Height of hoarding may beless than 2.4m (8ft), to accommodate tree branches that may be lower, or as approved byUrban Forestry. Within a City road allowance where visibility is a consideration, 1.2m (4ft)high orange plastic web snow fencing on a 38 x 89mm (2”x 4”) frame should be used. Thedetail on tree protection barrier construction is shown on Figure 4 in section 7 of thisdocument

• In specific situations where the required full minimum tree protection zone (TPZ) cannot beprovided, a horizontal (on grade) root protection, designed by a qualified professionalsuch as arborist or landscape architect, may be considered, subject to approval by UrbanForestry. Urban Forestry's objective is zero soil compaction within the tree protection zone,therefore best efforts must be made to achieve this objective using materials and bestpractices available that minimize the vertical loading and spread the loading horizontally.

• Any area designated for stockpiling of excavated soil must be outside of TPZs and beenclosed with sediment control fencing. Sediment control fencing shall be installed in thelocations as indicated in an Urban Forestry approved Tree Protection Plan. The sedimentcontrol fencing must be installed to Ontario Provincial Standards (OPSD-219.130 – seeSection 7, Figure 5) and to the satisfaction of Urban Forestry. When feasible, the sedimentcontrol fencing can be attached to the tree protection barrier as shown in Figure 6. Sedimentcontrol fencing near trees shall be constructed as per detail shown on Figure 6 of thisdocument

A sign that is similar to the illustration above may be required to be mounted on all sides of a tree protection barrier for trees protected by the Street Tree By-law and the Private Tree By-law. The sign should be a minimum of 40cm x 60cm and made of white corrugated plastic board or equivalent material. The sign may also be acquired from Urban Forestry Tree Protection and Plan Review (TPPR) district service counters.

5. Tree Protection Plan

All construction related applications must include a Tree Protection Plan that shows details of tree protection, prepared in conjunction with an arborist report or in consultation with an arborist, when protected trees are in proximity to the proposed work. All Tree Protection Plans must be legible, prepared at a usable metric scale and include the following information:

• Show all existing buildings, structures, hard surfaces and all existing trees within thearea of consideration (as defined in Section 2 of this document). Depending on theextent of site disturbance, trees on neighbouring properties may need to be included.Note that area of disturbance must include all areas that will be disturbed by theproposed work, including the areas required for over-dig, stockpiling, construction traffic,vehicular access and construction staging

• The extent of the crown (drip line) or the extent of minimum tree protection zone TPZ(whichever is greater) of each existing tree

• Proposed changes on site, including all proposed structures, services, hard surfaces andgrade changes

• Indicate vehicular access and construction staging areas. Areas proposed for temporarystockpiling of fill or excavated material shall be fenced with sediment control to preventsediment runoff

• Indicate location of any excavation that requires root pruning• Indicate trees proposed to be removed and/or injured• Highlight and label tree protection barriers and the proposed tree protection zones. (See

Table 1 to determine size of tree protection zone. Distances are to be measured frombase of tree)

• The extent of proposed tree injury, where applicable.• Include a comprehensive legend

See Section 6, Tree Protection Plan Notes, and Section 7, Tree Protection Plan Details, for further information.

6. Tree Protection Plan Notes

The following notes are to be included on tree protection plans submitted for construction related applications:

General Notes

• It is the applicants’ responsibility to discuss potential impacts to trees located near orwholly on adjacent properties or on shared boundary lines with their neighbours. Shouldsuch trees be injured to the point of instability or death the applicant may be held

responsible through civil action. The applicant would also be required to replace such trees to the satisfaction of Urban Forestry

• Tree protection barriers shall be installed to standards as detailed in this document andto the satisfaction of Urban Forestry

• Tree protection barriers must be installed using plywood clad hoarding (minimum 19mmor ¾" thick) or an equivalent approved by Urban Forestry

• Where required, signs as specified in Section 4, Tree Protection Signage must beattached to all sides of the barrier

• Prior to the commencement of any site activity such as site alteration, demolition orconstruction, the tree protection measures specified on this plan must be installed to thesatisfaction of Urban Forestry

• Once all tree/site protection measures have been installed, Urban Forestry staff must becontacted to arrange for an inspection of the site and approval of the tree/site protectionrequirements. Photographs that clearly show the installed tree/site protection shall beprovided for Urban Forestry review

• Where changes to the location of the approved TPZ or sediment control or wheretemporary access to the TPZ is proposed, Urban Forestry must be contacted to obtainapproval prior to alteration

• Tree protection barriers must remain in place and in good condition during demolition,construction and/or site disturbance, including landscaping, and must not be altered,moved or removed until authorized by Urban Forestry

• No construction activities including grade changes, surface treatments or excavation ofany kind are permitted within the area identified on the Tree Protection Plan or Site Planas a minimum tree protection zone (TPZ). No root cutting is permitted. No storage ofmaterials or fill is permitted within the TPZ. No movement or storage of vehicles orequipment is permitted within the TPZ. The area(s) identified as a TPZ must beprotected and remain undisturbed at all times

• All additional tree protection or preservation requirements, above and beyond theinstallation of tree protection barriers, must be undertaken or implemented as detailed inthe Urban Forestry approved arborist report and/or the approved tree protection planand to the satisfaction of Urban Forestry

• If the minimum tree protection zone (TPZ) must be reduced to facilitate constructionaccess, the tree protection barriers must be maintained at a lesser distance and theexposed portion of TPZ must be protected using a horizontal root protection methodapproved by Urban Forestry

• Any roots or branches indicated on this plan which require pruning, as approved byUrban Forestry, must be pruned by an arborist. All pruning of tree roots and branchesmust be in accordance with good arboricultural practice. Roots that have receivedapproval from Urban Forestry to be pruned must first be exposed using pneumatic (air)excavation, by hand digging or by a using low pressure hydraulic (water) excavation.The water pressure for hydraulic excavation must be low enough that root bark is notdamaged or removed. This will allow a proper pruning cut and minimize tearing of theroots. The arborist retained to carry out crown or root pruning must contact UrbanForestry no less than three working days prior to conducting any specified work

• The applicant/owner shall protect all by-law regulated trees in the area of considerationthat have not been approved for removal throughout development works to thesatisfaction of Urban Forestry

8. Permits for Tree Removal or Injury

If the full minimum tree protection zone (TPZ) as identified in Section 2 cannot be provided, a permit to injure the tree must be obtained.

Any requests for removal or injury of a tree protected by City by-laws must be made on the appropriate application forms and submitted to Urban Forestry at the appropriate address. Permit application forms are available at www.toronto.ca/trees. Any requests for tree relocation will be considered as a tree injury.

If approval is granted for removal of a City-owned tree, applicants will assume all costs involved, which include appraised tree value, removal, and tree replacement costs. If approval is granted for removal of private trees or trees in ravine and natural feature protected areas, the permit will be subject to conditions, including tree replacement. If approval is granted for injury of City-owned, private trees or trees in ravine and natural feature protected areas, the permit will be subject to conditions, including implementation of a Tree Protection Plan, as determined by Urban Forestry.

In some instances, where the tree is healthy and the management of the tree or forest cover has not been addressed to the satisfaction of Urban Forestry, requests received by Urban Forestry may be forwarded to a Community Council and City Council for approval.

Urban Forestry does not have the authority to issue a permit to injure or remove a heritage tree2. Such requests would be forwarded to a Community Council and/or City Council for approval.

9. Tree Guarantee Deposits

Tree Protection Guarantee

Urban Forestry may request a tree protection guarantee to secure the protection of trees that may be impacted by work on city streets, or to secure the satisfaction of all conditions of permit issuance. Tree protection guarantees held by the City shall only be released by the City provided that all construction activities are complete, compliance with all permit terms and conditions has been verified, there has been no encroachment into the minimum tree protection zone (TPZ) and the trees are healthy and in a state of vigorous growth.

Where Urban Forestry has confirmed an unauthorized encroachment into the TPZ or the terms and conditions of a permit have not been complied with, Urban Forestry will retain the guarantee until satisfactory compliance.

It is the applicant’s responsibility to submit a written request to Urban Forestry for the refund of the tree protection guarantee deposit as soon as construction and landscaping is completed.

Tree Planting Security

Urban Forestry may request a tree planting security deposit in an amount equal to the cost of planting and maintenance for two (2) years in order to ensure compliance with approved landscape or replanting plans. The security deposit may be held by the City after the planting of the trees for a period of two (2) years and shall be released by the City provided that the trees have been maintained, are healthy and in a state of vigorous growth upon inspection, two (2) years after planting. It is the applicant’s responsibility to advise Urban Forestry that trees have been planted in accordance with approved plans, in order that the two (2) year maintenance period begin.

Prior to release by the City, any dead/dying trees must be replaced, deadwood and sucker growth should be pruned, and mulch should be topped up where necessary. If stakes and ties were used, they must be removed within one (1) year. Any encroachments are to be removed prior to assumption, including walkways, timbers or bricks that result in increased height of soil or mulch around the trees, and lights in trees.

It is the applicant’s responsibility to submit a written request to Urban Forestry for the refund of a Tree Guarantee Deposit, two (2) years after the completion of all construction activity and/or two (2) years after tree planting. This request should be made during the growing season, not while

July 2016 16


the trees are dormant, so that a site inspection can be arranged to confirm the trees are acceptable. The City will not release security deposits where trees are not in good condition, or if there are encroachments.

Financial securities must be in the form of a certified cheque, letter of credit or an alternative acceptable to Urban Forestry, with amounts payable to the Treasurer, City of Toronto.

10. Emergency Repairs to Utilities

The utility company is responsible for notifying Urban Forestry by calling 311 as soon as possible when by-law regulated trees are involved, so that an inspector can be dispatched. Urban Forestry staff may be contacted after hours by calling 311, and requesting the assistance of an on-call Urban Forestry inspector.

11. Tree Species that are Intolerant of ConstructionDisturbance

The following tree species are intolerant of construction disturbance, and tree protection plans must take this into account. The tree protection zones required by these species may need to be quite extensive to avoid damage to the roots and crown associated with compaction, excavation or construction above grade that will impact the branches.

Acer rubrum (red maple) Acer saccharum (sugar maple) Betula papyrifera (paper birch) Carya glabra (pignut hickory) Fagus grandifolia (American beech) Liriodendron tulipifera (tulip tree) Ostrya virginiana (ironwood) Pinus resinosa (red pine) Pinus strobus (white pine) Prunus serotina (black cherry) Quercus alba (white oak) Quercus velutina (black oak) Tsuga canadensis (eastern hemlock) Tilia americana (basswood)
