2 Grandview Heights #2 NCP Page 1 of 5 Preliminary Tree Review 1.0 Introduction The City of Surrey has a large population of trees, including large diameter second growth native conifers, significant stands of native deciduous species and introduced ornamental species, all of which contribute to the City s unique visual character. In addition to their aesthetic value, trees also offer shade, cool the air, provide visual screening and noise abatement, reduce erosion and storm water runoff, provide recreation opportunities and can increase property values. Trees also offer benefits toward climate change, particularly through carbon sequestration. Successful tree preservation within developable lands presents a challenge which requires careful planning and long term maintenance. In order to meet this challenge, the City has recently implemented its revised Tree Protection By-law No 16100, and continues to include tree preservation as a component of its long range planning goals and short range planning process. has been retained to assist by providing a preliminary or cursory arboricultural assessment outlining trees and stands of trees considered worthy of preservation efforts in relation to the urban planning module for the Grandview Heights Neighbourhood #2, Neighbourhood Community Plan (NCP). Planning and rezoning objectives for this NCP area consist of a mixture of land uses and varying residential densities, along with dedicated park / open space and school and civic utility sites. Grandview Heights Neighbourhood #2 is situated in south central Surrey and extends east from 161A Street to 168 th Street, and south of 24 th Avenue to 15 th Avenue. The western boundary is further defined by the hydro right of way (ROW) located northeast of HWY 99. In order to gather information for this study, we drove and walked the parcel over several days in December 2007 and through the winter of Although individual trees have not been surveyed for this study, accurately locating trees is a vital part of the tree preservation process and should be required as more specific land uses become apparent at the application stages. Access to a number of properties was limited, so this assessment should be considered preliminary and does not reflect the full extent of tree preservation opportunities that are believed to exist within the entire study area. This report provides a review of trees and stands of trees with varying levels of preservation potential located within the study area. Trees were considered for their preservation potential based on age, structure, health and species considerations and limited to size and species offered protection under Surrey s Tree Protection By-law. Preservation ratings were classified from poor to good, based on a preliminary visual assessment and location, with respect to the proposed future land use. 2.0 Findings Ecosystems within the province of BC have been classified on a hierarchical system based on climate, soil, topography and their particular plant communities. The Grandview Heights Neighbourhood #2 is situated within the moist maritime coastal Douglas fir subzone (CDFmm), which is found in low elevations on the leeward side of

3 Grandview Heights #2 NCP Page 2 of 5 Preliminary Tree Review Vancouver Island and the southern Lower Mainland. This subzone typically has warm and dry summers with mild, wet winters 1. Forests within this zone are dominated by Douglas fir, as well as bigleaf maple and black cottonwood. The coniferous component of the typical forest also includes, to a lesser extent, western redcedar, grand fir and western hemlock. Understory vegetation found within this subzone includes salal (Gaultheria shallon), dull Oregon grape (Mahonia nervosa), ocean spray (Holodiscus discolor), salmonberry (Rubus spectabilis) and Indian plum (Oemleria cerasiformis). The north section of the NCP area is transitional to Coastal Western Hemlock Zone (CWH). Ground cover within the Grandview Heights #2 NCP is varied, with significant areas cleared of trees and currently used for agricultural production, and smaller hobby farms. Significant areas of the site have been developed to provide large residential lots where turf grass is the primary ground cover, along with small stands of remnant trees or single trees planted post development. Forest cover includes areas with stands of second growth trees, as the area has been repeatedly logged over the last 80 years. Our review identified the forest cover within the site to consist predominantly of native species in varying successional stages, including early successional pioneer deciduous species, stands with remnant second growth mixed species and coniferous dominated areas. Stand size ranges from small groups of remnant conifers consisting of 5 10 trees, to large continuous deciduous dominated forests greater than 3 hectares in size. The larger coniferous dominated coverage generally occurs at the north end of the site, north of 20 th Avenue, while the large deciduous stands are in the south central area. Small groups of trees scattered around the area are remnant from past land clearing activities or were planted as windbreaks or for other uses. Non native species planted as ornamentals are found throughout, but are predominately located on residential lots in the north and east sections of the area. The most common coniferous species identified while conducting this review were Douglas fir (Pseudotsuga menziesii), western redcedar (Thuja plicata) and, to a lesser extent, western hemlock (Tsuga heterophylla). The predominant deciduous species include black cottonwood (Populus balsamifera ssp. trichocarpa), red alder (Alnus rubra) and bigleaf maple (Acer macrophyllum), with a lesser component of paper birch (Betula papyrifera) and a few indigenous cherry (Prunus emarginata). Red alder is a relatively fast growing, short lived (40 60 years) species that grows in full sunlight. Its shade intolerant nature means they readily colonize recently disturbed areas that have little or no cover, and can often flourish in nitrogen poor soils. Black cottonwood is also a fast growing pioneer species requiring full sunlight that typically colonizes alluvial sites, riparian areas and moist woodlands. Although bigleaf maple is not considered a pioneer species, it can also rapidly invade disturbed areas. Similar to the previous two species, it is also fast growing. Fast growth among the native deciduous species produces 1 Green, R.N. and Klinka A Field Guide for Site Identification and Interpretation for the Vancouver Forest Region. Ministry of Forests.

4 Grandview Heights #2 NCP Page 3 of 5 Preliminary Tree Review structurally week trees with limited trunk tapers, branchless stems and high canopies, when growing in a competitive environment. In addition, many of the trees in deciduous dominant stands will display leans and phototropic sweeps to their lower and middle stems as a response to their quick growth and competition for light. Blow down among the shallow rooted trees on wetter sites and partial stem failure among others is relatively common. Due to their structural limitations and high risk of failure, retaining individual or small stands of the native deciduous trees is not a recommended practice. These types of stand are typically best suited for lower density residential development projects or retention in large continuous stands, such as riparian corridors or greenways and natural areas. 3.0 Planning and Design Successful long term retention requires that trees be considered an important part of the development project and that the preservation initiative be included in the early planning and design phases. Early on, trees should be evaluated for preservation suitability based on health, structure, age and species factors. Healthy, vigorous trees are more able to adapt to root loss and the environmental changes that occur after construction, while trees of poor structure or with defects such as extensive decay, poorly attached limbs and poor crown structure, are not considered suitable for areas where people or property could be targets. Older, mature trees are generally less tolerant to environmental changes, and preference should be given to younger trees of species that are more tolerant to changes in hydrology, sunlight, root loss and other post construction environmental changes. Another consideration during the evaluation process is single specimen versus groups of trees. When compared to trees growing in a competitive, forested environment, single specimen trees generally have an open grown form with a symmetrical canopy, relatively larger root plate and good trunk taper. Trees growing in the interior of a stand and suppressed trees generally have little trunk taper, high canopies and smaller root plates. When surrounding trees have been removed and wind exposure is increased, the new edge trees are more prone to failure and can become liabilities. For these reasons, forest grown trees or small stands should be retained in groups of a size that are able to maintain the stand integrity. Although larger stands of trees can be reduced in size, each stand should be evaluated for its preservation suitability based on species composition, age class and canopy structure. The City has identified, in the North Grandview Heights NCP Amendment section , a number of key design stage policies necessary for successful tree preservation. One of these policies is to accurately locate trees or trees stands prior to the design stage and adjust building envelopes or clusters of development to accommodate the tree resource. Providing and maintaining adequate no disturbance zones around retained trees throughout the development and construction phases is vital to the success of tree preservation. No disturbance zones must also consider not only the disturbance required for the building footprint, but the additional space necessary to excavate for foundation or other below ground works. Quite often this can encroach into the prescribed no disturbance zones. Design staff should provide additional space adjacent to the no

5 Grandview Heights #2 NCP Page 4 of 5 Preliminary Tree Review disturbance zones to accommodate the construction based on the level of disturbance necessary for the proposed works. 4.0 Discussions The field review has identified a number of areas with varying levels of tree preservation opportunities, including small and large stands of native trees, hedgerows, windbreaks and single specimen ornamentals of introduced species. These areas have been numbered to correspond with the areas on the aerial photographs attached at the end of this document. It should be noted that this study is an overview and does not include a review of all trees within the NCP area. Many additional trees will become of size offered protection by Surrey s Tree Protection By-law over the coming years when the area progresses through the development stages. Also, access to a number of areas was limited or restricted and, therefore, the tree resource could not be reviewed thoroughly or at all in some cases. In addition, trees were not assessed for their hazard potential, but this is typically a component of detailed arboricultural reviews which accompany development or building applications and is best done at that time. A number of moderate to good quality stands of native conifers have been identified for preservation opportunities throughout the study area. Preserving the native conifers, which are typically the dominant trees on the landscape, will help preserve the neighbourhood s visual character and may provide recreational opportunities depending on stand size. Preserving the large diameter native conifers along roadways requires careful planning, coordination between all parties and departments involved, a willingness to utilize alternate design strategies (including special foundations, pavement designs, sidewalk surfaces) and a thorough review of all underground service routes. In addition to the native conifers, a number of introduced species planted for their ornamental value have also been identified, some of them of significant quality. These include, but are not limited to, a number of medium to large diameter giant sequoia s (Sequoiadendron giganteum), oaks (Quercus sp) and walnut (Julgans sp). To ensure the successful preservation of these trees, project planning should provide adequately sized no disturbance zones and recommendations for long term maintenance. In addition to the single specimen non native ornamental species, a number of Lombardy poplar (Populus nigra) hedgerows have been planted in the area as windbreaks or along fence lines. Although these trees are not typically planted in an urban setting due to their short lifespan, tendency to shed limbs and large volume of leaf litter, we believe incorporating these hedgerows into the design scheme can help preserve the rural heritage of the area, assuming adequate setbacks can be achieved. Vital components of the successful tree preservation plan that are often overlooked are the post construction evaluation and long term care and maintenance phases. Post construction evaluation typically involves an evaluation of the health and stability of the retained trees to determine if they have been impacted by construction. Symptoms of stress or decline can present themselves years after the disturbance, so long term monitoring is often required. Monitoring includes observing for changes in foliage

6 Grandview Heights #2 NCP Page 5 of 5 Preliminary Tree Review colour and density or the development of leans or other indicators. Long term care involves remedial actions such as pruning, weed control, supplemental watering and mulching that can help alleviate the stresses placed on trees that often accompany changes in hydrology and other environmental factors post construction. The future provides opportunity to design and build developments within the NCP study area offering good tree preservation initiatives, however, it requires a careful planning approach. Thorough consideration must be given to each development to identify the suitable trees and establish adequate areas of no disturbance. Grades must be maintained within tree preservation areas. The guidelines established at the design process must be adequate to ensure only minimal impact to the trees and their root systems. These guidelines must be enforced through the construction process and beyond into the evolution of the development. Ongoing reviews of the trees for indications of decline or distress is to be considered an integral part of the tree preservation initiative. 5.0 Limitations This Arboricultural field review report is based on site observations on the dates noted. Effort has been made to ensure that the opinions expressed are a reasonable and accurate representation of the condition of the trees reviewed. All trees or groups of trees have the potential to fail. No guarantees are offered or implied by Mike Fadum and Associates Ltd. or its employees that the trees are safe given all conditions. The inspection is limited to visual examination of accessible items without dissection, excavation, probing, coring or climbing. Trees can be managed, but they cannot be controlled. To live, work or play near trees is to accept some degree of risk. The trees within this review area were reviewed only as a general overview. Hazard assessments were not performed.
