3 1.0 OVERVIEW This Tree Conservation Report has been prepared for Nortrax Canada Inc. ( ) in support of a site plan control application and zoning by law amendment to permit the development of 190 David Manchester Road in Stittsville, Ontario. The approximately six (6) hectare property at 190 David Manchester Road, north of Hazeldean Road, is currently vacant. The parcel is being proposed as a heavy equipment sales and service facility, with an area of approximately 3,600 square meters. The proposed building will include office space, a showroom for the display of equipment, service bays and repair facilities. The subject land is currently described legally as Part of Lot 1, Concession 4, Geographic Township of Huntley, now in the City of Ottawa, and designated as Parts 2 and 3 on Plan 4R and Parts 5 and 7 on Plan 4R The site is currently zoned Rural Countryside in the City of Ottawa Zoning By law. This Tree Conservation Report summarizes the condition of the current vegetation, defines which trees will be impacted by the development of this project and recommends mitigation measures to preserve a variety of vegetation that will improved the overall site plan and promote a diverse vegetative landscape. 1

4 2.0 INTRODUCTION This Tree Conservation Report outlines the condition of all existing vegetation on site, the impact of development on the vegetation and the mitigation measures recommended preserving and minimizing impact on the conserved vegetation. The protection of a variety of trees on site will serve to improve the overall residential development and promote a diverse vegetative landscape. A vegetation field survey was conducted on June 3, 2013, by Carina Thulin Lood from McIntosh Perry Consulting Engineers (McIntosh Perry) to review the species and basic conditions of the trees located at 190 David Manchester Road, north of Hazeldean Road in Stittsville, Ontario. To confirm the location and caliper of a number of Distinctive Trees observed on the property during the initial site visit, a second field survey was conducted on October 24, The objectives of this Tree Conservation Report are: To describe the existing woody vegetation (trees and large shrubs) growing on site including species composition, size, vigour and health condition; To describe the existing woody vegetation growing on the adjacent parcels; To assess the woody vegetation functions including environmental value, ecological function, aesthetics, sensitivity to grade changes, drainage, sun and wind exposure, etc.; To produce a document describing the forested and open areas including stands of trees and individual trees which may be candidates for consideration of conservation measures; and To provide a professional opinion on the retention of woody vegetation Definitions Some of the basic terms used within this document and on the plans have been defined below. Potential protection techniques and remediation measures have been noted. Critical Root Zone (CRZ): Diameter at Breast Height (DBH): Dieback: Drip Line: Zone under a tree where there should be no disturbance before, during and after construction. The CRZ is established as being 10 centimetres from the trunk of a tree for every centimetre of trunk diameter. Diameter of a tree trunk measured at 1.4 metre above ground, standardized by the Council of Tree and Landscape Appraisers and the International Society of Arboriculture. Condition in which the ends of the branches are dying. Perimeter of the area under a tree delineated by the crown. 2

5 Leader: Scaffold Branches: Significant Tree: Significant Woodland: The primary terminal shoot or trunk of a tree. The permanent or structural branches of a tree. Tree / shrub deemed valuable because it is unusually beautiful or distinctive, comparatively old, distinctive in size or structure for its species, rare or unusual in the subject area, provides a habitat for rare or unusual wildlife species in the subject area, or has an historical, cultural, or landmark significance. Woodland that contain mature stands of trees 80 years or older, have interior forest habitat more than 100 metres from forest edge, and are adjacent to a surface water feature. Specimen Tree: Individual tree located in the middle of a field or open space. A specimen tree is not automatically a significant tree. Stress: Structural Defect: Topping (Topped): Tree Protection Zone (TPZ): Tree Sapling: Tree Seedling: Tree Shoots: Any factor that negatively affects the health of a tree. Flaws, decay, or other faults in the trunk, branches, or root collar of a tree, which may lead to failure. Cutting back a tree to buds, stubs, or laterals not large enough to become a new leader on the tree. The area surrounding a tree that is marked and fenced off and where there is no storage of materials of any kind, no parking or moving of vehicles, and no disturbance of the soil or grade. Young tree measuring more than 1.50 metres high. Young tree measuring less than 0.60 metre high. Tree shoots are sprouts that emerge from dormant buds along the trunk or branch of a tree. In an urban environment shoots are often associated with stress to the tree. Trees with severe dieback due to winter injury, drought and salt spray often produce many shoots as a means of compensating for the loss of leaf surface due to stress or injury. 3

6 Tree Suckers: Tree Whips: Vigour: Tree suckers are sprouts that form from the roots of existing trees and tend to form new trees or shrubs. In an urban environment suckers can be associated with stress to the tree and are prevalent after a disturbance such as when mature trees are cut down. Some tree species have the tendency to sucker. Young tree measuring between 0.60 and 1.50 metres high. Overall health; capacity to grow and resist stress. 4

7 3.0 CURRENT VEGETATION This inventory and analysis was based on a visual inspection of the tree species and their condition. The species were determined based on leaf, bark and buds identification. The vigour was assessed based on visible defects only. 3.1 Methodology and Observations The parcel of land is currently vacant. It is located in the St Lawrence Lowlands Region, within the Mixedwood Plains Ecozone (Ecological Stratification Working Group, 1995). According to the Environmental Impact Statement prepared by McIntosh Perry (July, 2013), the subject property was observed to be a moderately disturbed landscape, in particular within the hydro corridor and open grassland area. Due to the large number of existing trees, a complete assessment of every tree was not possible. Instead, a stratified sampling technique was used to sample the existing vegetation on the property. Based on aerial photography and a site inspection, the subject land was divided into different vegetation zones in accordance with the methodology established in the Environmental Impact Statement (2013). Each one of these vegetation zones, or strata, was visually assessed and sampled to determine the overall species composition as indicated in Appendix A: Table 1 Stratified Sampling of Existing Vegetation. Based on species composition, the parcel of land was divided into four different vegetation zones: (1) Cultural Meadow, (2) Common Juniper Cultural Thicket Type, (3) Dry Fresh Pine Coniferous Ecosite, and (4) Fresh Moist Sugar Maple Deciduous Forest Ecosite. Table 1 is to be read in conjunction with the Current Vegetation Plan (TC 1) accompanying this report. Figure 1. Vegetation Zone 1 Cultural Meadow 5

8 Vegetation Zone 1 Cultural Meadow (CUM) Located in the middle of the property and adjacent to Highway 7, Vegetation Zone 1 Cultural Meadow is mostly composed of various types of graminoides and forbs. However, there are signs of natural regeneration consisting of stands of different pioneer species, including Populus tremuloides (Trembling Aspen), Populus balsamifera (Balsam Poplar) and a few Pinus strobus (White Pine). In addition, the vegetation in this area also includes coniferous shrubs, such as Juniperus communis (Common Juniper) and Thuja occidentalis (Eastern White Cedar). As secondary succession species, the trees observed in this area are mostly saplings. In the middle of this area is a shallow depression, with willow shrubs (Salix spp.) growing. In general, the vegetation is in good condition and show signs of good health and vigour. There are no significant trees in this area. Vegetation Zone 2 Common Juniper Thicket Type (CUT) Located within the hydro corridor, the vegetation community in this area can be classified as a Common Juniper Thicket Type (CUT) (McIntosh Perry, 2013). The dominant woody plant in this area is the common juniper. Other species observed within this vegetation community are: Pinus strobus (Eastern White Pine), Populus tremuloides (Trembling Aspen), Acer saccharum (Sugar Maple) and Acer rubrum (Red Maple). These are young trees and no mature trees with a caliper exceeding 50cm DBH were observed within the hydro corridor on the subject property (McIntosh Perry, 2013). Figure 2. Vegetation Zone 3 Dry Fresh Pine Coniferous Ecosite 6

9 Vegetation Zone 3 Dry Fresh Pine Coniferous Ecosite (FOC1) Along the edges of the property, there are mature forested areas with slightly different composition of species and density of vegetation. Vegetation Zone 3 Dry Fresh Pine Coniferous Ecosite consists of approximately equal percentages of coniferous and deciduous trees in open stands that are not particularly dense. In terms of species composition, the vegetation includes the following species: Pinus strobus (White Pine), Picea glauca (White Spruce), Thuja occidentalis (Eastern White Cedar), Acer saccharum (Sugar Maple), Betula papyrifera (Paper Birch), Betula alleghensis (Yellow Birch), Fraxinus pennsylvanica (Green Ash), Ostrya virginiana (Iron Wood), Populus tremuloides (Trembling Aspen), Populus balsamifera (Balsam Poplar) and Ulmus americana (American Elm). In terms of species composition, there is no predominant species but the area is mixed. There are a few Distinctive Trees within this vegetation community, including Pinus strobus with a Diameter at Breast Height (DBH) exceeding 50 centimeters. The approximate locations of these trees are shown on the accompanying drawings TC1 Existing Conditions and TC2 Proposed Development. Two of these trees are located within the David Manchester road allowance. Figure 3. Vegetation Zone 3 Dry Fresh Pine Coniferous Ecosite 7

10 Figure 4. Vegetation Zone 3 Dry Fresh Pine Coniferous Ecosite Vegetation Zone 4 Fresh Moist Sugar Maple Deciduous Forest Ecosite (FOD6) Referring to the Environmental Impact Statement, dated July 2013, this vegetation community is classified as a Fresh Moist Sugar Maple Deciduous Forest Ecosite. It is composed of the following species: Acer saccharum (Sugar Maple), Fraxinus pennsylvanica (Green Ash), Populus tremuloides (Trembling Aspen), Populus balsamifera (Balsam Poplar), Quercus rubra (Red Oak) and Thuja occidentalis (Eastern White Cedar). There are no mature trees in this area with a caliper exceeding 50 cm DBH (McIntosh Perry, 2013). In terms of grade changes on the subject lands, the difference in elevation between the highest point and the lowest point is approximately three (3) metres. In general, the subject land is sloping towards the middle of the property where a large depression was observed during the vegetation field survey. Furthermore, the western portion of the subject land was defined by a small depression located adjacent to David Manchester Road. This area was full of water during both field surveys. 3.2 Environmental Value of the Trees and Their Ecological Function As noted in the Environmental Impact Statement (2013), the Goulbourn Wetland Complex is located approximately 50m north of the subject land. This Provincially Significant Wetland (PSW) provides habitat for nesting colonial water birds. It also contains the headwaters to tributaries for a number of local rivers and creeks, such as Huntley Creek and the Carp River. This type of wetland is highly resilient and it is therefore anticipated that there will be no impacts due to the proposed development. 8

11 The subject property is also located on the northwest border of the Highway 7 North, Area 419 Rural Natural Feature (RNF) (McIntosh Perry, 2013). This RNF is rated as one of the most significant areas in the former Regional Municipality of Ottawa Carleton for maintaining biodiversity and ecological functions (McIntosh Perry, 2013, p. 8). In terms of environmental value, the vegetation communities on site provide a number of benefits, including: biodiversity, habitat, storm water detention, reduced storm water runoff, ground water recharge, and carbon sequestration. In addition to these benefits, the vegetation also serves a number of ecological functions in terms of providing habitat for a variety of species and, thereby, contributing to biodiversity. Nevertheless, the forested areas on the subject property should not be considered a part of any Significant Woodlands due to the fragmentation caused by the adjacent transportation corridors: Highway 7 and David Manchester Road (McIntosh Perry, 2013). Furthermore, none of the trees on the subject lands are considered to be Species at Risk (SAR). Overall, the majority of the trees found on the subject lands are not of significance with the exception of a few Distinctive Trees with a caliper exceeding 50cm DBH. Any loss of vegetation on site would therefore not result in any negative effects on the Significant Woodlands present in the RNF (McIntosh Perry, 2013) or the removal of any SAR trees. Even though the subject property has habitat present to accommodate a few bird, vegetation and reptile species listed as SAR (McIntosh Perry, 2013, p. 12), there were no SAR observed on the property during the 2013 terrestrial field surveys or during the targeted SAR field investigations (McIntosh Perry, 2013). A tree species of concern found on the subject lands are green ash. The ash tree is commonly found in wooded areas throughout Ottawa and the rest of Ontario. Since 2008 ash trees located in the Ottawa region are affected by the Emerald Ash Borer (EAB). The EAB is a non native, wood boring beetle attacking and destroying all species of ash trees. Because of the impacts on ash trees and to limit the spread of EAB, the Canadian Food Inspection Agency has issued a ministerial order to prohibit movement of firewood and ash tree products such as nursery stock, logs, branches and wood chips from areas of Ottawa to any other surrounding regions. During our field investigation we did not observe any signs of EAB on any ash trees. However, precautionary measures will be required when removing and working around any ash tree. Special mitigation measures will be described in the following section of the report. All efforts should be made to protect and preserve as much natural vegetation as possible, if it fits in with the proposed development. Factors influencing preservation will be the amount of grading required at the base of the trees and the proximity of built structures and/or servicing. Care will have to be taken to reduce the impact of construction on any trees that are to be preserved. Most of the construction impacts for this project will be in the form of new buildings, new hard surfaces and the grade change impacts on the roots of the trees. 9

12 4.0 PROPOSED DEVELOPMENT AND CONSERVED VEGETATION The project for 190 David Manchester Road involves the development of the property into a sales and service center. The proposed development shown on the Proposed Development and Conserved Vegetation Plan (TC 2) indicates the location of the proposed building, access roads, parking lot, storm water management pond, fences, and utilities. 4.1 Conserved Vegetation As indicated on the accompanying drawing, Proposed Development and Conserved Vegetation Plan (TC 2) approximately half of the existing vegetation will be protected and preserved. It is also anticipated that much of the vegetation along the hydro easement which consist in Vegetation Zone 2 Common Juniper Thicket Type will be protected and preserved with exception along the proposed fence. Much of the vegetation on the northern and western side of the subject property will also be preserved where it is located in proximity to the Goulbourn Wetland Complex a Provincially Significant Wetland. All conserved vegetation to be preserved and located near any construction phase should be protected at all times using the mitigation measures indicated below. 4.2 Impacted Vegetation As indicated above, approximately half of the existing vegetation located on the subject lands known as 190 David Manchester Road will be impacted by the construction of the new sales and service facility. The vegetation in the affected area belongs to three different vegetation communities: Vegetation Zone 1 Cultural Meadow, Vegetation Zone 3 Dry Pine Coniferous Forest Ecosite, and Vegetation Zone 4 Fresh Moist Sugar Maple Deciduous Forest Ecosite. As noted in the Environmental Impact Statement (2013), the subject property is a moderately disturbed landscape, especially pertaining to the hydro corridor and the cultural meadow. The forested areas are fragmented due to their location adjacent to transportation corridors. Therefore, the loss of vegetation on site is not anticipated to have any significant impacts on any Significant Woodlands located nearby. In addition, it will not negatively affect any SAR since none were observed on site. The complete list of vegetation zones to be removed due to the development of the subject lands can be found in Appendix A Table 1 Stratified Sampling of Existing Vegetation. This Table is to be read in conjunction with the Proposed Development and Conserved Vegetation Plan (TC 2) accompanying this report. Impact on vegetation can be due to construction of the sales and service facility, grade change, changes to drainage patterns, and effects of impervious surfaces and new buildings. Furthermore, vegetation will also need to be removed due to the construction of a fence surrounding the property, as well as widening of David Manchester Road. As noted on the accompanying drawing, TC1 Existing Conditions, there are two Distinctive Trees located within the road allowance. Special precaution to adjacent vegetation to remain should be taken when removing any trees. 10

13 4.3 Tree Protection Measures Trees can be damaged in a number of ways during construction. The most common injury is to the crown or trunk. These injuries are visible and permanent and in some cases can be fatal to the tree. The roots are susceptible to physical injury through the cutting of the roots, soil compaction and/or smothering of the roots. The roots of a tree are located in the top 150 to 250 millimetres of soil and can very easily be inadvertently damaged. A vehicle parking under the root zone of a tree can compact the soil reducing the roots ability to absorb nutrients and uptake water. A change in grade of more than 150 millimetres over the roots will reduce its health and vigour. At any time no root system, trunk or branches of any tree should be damaged Protection of the Root Systems Within the critical root zone (CRZ) of trees to be conserved and located within construction limits there must be: No disturbance or alteration of the existing grade of any kind without approval; No addition of fill, excavating, or scraping to change the grade; No signs, notices or posters to be attached to any trees; No storage of construction materials or equipment; No storage of surplus soil, construction waste, or debris over the root systems of the protected trees; No disposal (dumping or flushing) of contaminants or liquids; and, No movement of vehicles (personal or business), equipment or pedestrians. At any time during construction, root systems should not be damaged. In the event that a tree has roots that will be impacted by construction work, the Contractor shall only tunnel or bore when digging within the CRZ. The roots should only be cut by hand with a sharp spade or knife at the limit of disturbance prior to any construction activities. This will ensure that the roots are not disturbed more than necessary. Any root pruning requires the service of a Certified Arborist or Qualified Tree Worker under the supervision of a Certified Arborist. Any roots that are exposed must be covered with native topsoil immediately, to ensure that the roots do not dry out or have any further damage occur to them. All remedial works must be conducted by a certified care professional to ensure proper care is administered in order to enable the continued health of the trees Fencing Before construction, fencing should be erected at the critical root zone (CRZ) of trees located in the construction area or within 15 metres of the construction zone to ensure that this protection is achieved. Tree protection barriers shall be installed according to information indicated on the Proposed Development and Conserved Vegetation Plan (TC 2) drawing. Fencing shall be maintained erect and in good repair at all 11

14 times during construction operations, and shall be removed upon completion when agreed by City staff. Temporary removal of fencing will not be considered without approval Additional Protection Measures When working near vegetation the Contractor shall ensure that exhaust fumes from all equipment are NOT directed towards any tree s canopy. The Contractor shall take every precaution necessary to prevent damage to the trees to be conserved. Where limbs or portions of trees are removed to accommodate construction work, they will be removed carefully in accordance with accepted arboricultural practices. Where necessary, the trees will be given an overall pruning to restore the appearance of the trees. Not more than one third of the total branching shall be removed at a single operation. Trees that have died or have been damaged beyond repair by the Contractor shall be removed and replaced by the Contractor at their own expense with trees of equal size and species or as directed by City staff. Damages will include: Any physical damage on tree bark; Any broken branches; Equipment and materials stored within the protected areas and beyond the limits of the contract; and Refueling of equipment within the protected areas Special Measures for the Removal of Ash Trees Even though we did not see any signs of EAB on any ash tree found on site the insect can be present. The Contractor will be required to follow special measures when removing or pruning ash trees due to the development of the new subdivision. Because of the potential of EAB on site and the location of the City of Ottawa within the EAB Regulated Areas / Ministerial Order Area, any non processed (not debarked) ash products (logs, branches, etc.) can only be moved freely inside the jurisdiction of the City of Ottawa. In order to limit the movement of ash products for long distances within the City of Ottawa limit, different options are available for the Contractor when processing ash products: Moving logs and firewood from large branches (more than four inches in diameter) as close to the Village of Carp as possible; Bringing a portable sawmill on site to process the timber; Chipping and disposing all small branches (less than three to four inches diameter) on site; Moving all ash products to the Trail Road Waste Disposal Facility. 12

15 When cutting ash trees the Contractor shall separate ash products from other timber species on site to ensure the products are easily identified for processing. The Owner and Contractor shall also ensure that any ash products will not be move outside the EAB Regulated Areas / Ministerial Order Area. 4.4 Tree Planting Recommendations Tree planting for the subject land known as 190 David Manchester Road should implement the natural character of the conserved vegetation on site as much as possible. Where possible the use of native, noninvasive tree species should be preferred. According to the Geotechnical Report prepared by exp Services Inc., dated June 18, 2013, the investigation revealed a 150mm to 350mm layer of topsoil. Beneath this layer, fill extends to a depth of 0.85m to 1.5m comprised of a mixture of sand with variable proportions of silt, gravel, clay and topsoil. Within the fill matrix, the presence of rootlets, cobbles, boulders and rock fragments was also observed. At depths ranging from 0.15m and 2.4m, a transition layer of weathered bedrock was observed inter bedded with silty sand and bouldery till. The bedrock underlying the site is comprised of limestone with shale partings of the Ottawa formation. Based on the Geotechnical Report, our field observations and the proposed development for the site, the following represent a list of tree planting recommendations: The poor soil conditions in certain areas will require the provision of good quality planting soil for all planting beds and new trees in order to optimize growth. To promote the survival of any newly planted trees we recommend planting saplings and/or smaller caliper trees with small root systems. Planting proposed on the northeast section of the site, especially located within Vegetation Zone 1 should supplement the existing natural regeneration area. A combination of deciduous and coniferous vegetation should be used in order to provide a visual screen of the proposed sales and service facility from TransCanada Highway 7, and to provide seasonal interest. A visual screen should be planted along the southern property line to provide separation between the Nortrax Canada Inc. and Play Value site. Tree and shrub plantings should be used to enhance the appearance of the proposed sales and service facility from David Manchester Road and TransCanada Highway 7. Since some of the trees observed on site are Distinctive Trees, every effort should be taken to protect and preserve these trees. 13

16 5.0 CONCLUSION There are several Distinctive Trees that are in good condition and should be protected during construction on the site following the tree protection measures described in this report and on the accompanying drawings. Every effort should be made to protect and preserve the existing vegetation, while allowing for construction of the proposed sales and service facility. Any planting scheme should consist of native vegetation that implements the natural character of the area while taking into account the poor soil conditions on site. In accordance with the City of Ottawa s Scenic Highway Corridor requirements, every effort should also be made to present an attractive impression of the site as viewed from Highway 7.
