1. Introduction
1.1 Background
1.1.1 AECOM has been commissioned to prepare and submit a written Arboricultural Report for existing trees within part of the Calverley Grounds Site in Tunbridge Wells, Kent.
1.1.2 The scope of work includes a tree survey to BS5837:2012 to allow the production of a tree schedule and the production of a tree constraints plan to show the above and below ground spatial constraints affecting operations within the Site. This information is intended to inform the assessment of the arboricultural constraints and opportunities in relation to the future development of the Site.
1.2 Methodology
1.2.1 The tree survey has been based on the topographical survey (ref: T516-236L1 and L2 by Terrain dated June 2016 and Z TLA L C-01 by Townshend dated June 2016). All work has been conducted in accordance with the requirements of BS5837:2012 Trees in relation to design, demolition and construction – Recommendations (BS5837). Where tree locations were not recorded accurately on the topographical survey plan they have been plotted indicatively on site, with reference to adjacent features and aerial photography and have been marked with a ‘*’ on the survey plans. Where new features or tree protection measures are to be positioned in proximity to these trees, relative positions must be accurately measured out on Site.
1.2.2 Fieldwork was undertaken in July 2016 during which dimensional data and observational information were collected. A diameter tape measure was used to measure stem diameters where feasible.
1.2.3 The fieldwork informing this report has comprised a preliminary, non-intrusive, visual survey undertaken from ground level with the specific intention of evaluating the quality and benefits of trees on Site. Where further inspection is deemed appropriate to ascertain the condition of the tree or other arboreal features, this has been identified within the preliminary management recommendations. Average dimensions or dimensional ranges have occasionally been used where appropriate to best describe features.
1.2.4 A Tree Survey Schedule is included as Appendix A of this report and this corresponds with the Tree Survey Plan which shows the position of trees and the spatial constraints associated with them. This drawing is included as Appendix B.

2. General Arboricultural Principles
2.1 General Principles
2.1.1 Trees are dynamic living organisms which provide essential benefits to society and the wider environment. Any project with the potential to impact on trees must take into consideration the value of trees on Site, the impact of any proposed activity along with any potential future conflicts. Suitable measures to safeguard retained trees or mitigate the loss of trees to be removed will need to be fully considered and may be a condition of planning consent.
2.1.2 Tree branches and roots frequently grow across Site boundaries and off Site trees can pose a significant constraint and should be carefully considered when assessing the developable space within a Site.
2.2 Below ground constraints
2.2.1 Below ground tree roots and the soil environment in which they grow needs to be protected if the tree is to be retained. Trees grow in association with fungi and other soil organisms which are of key importance to tree health. Roots are essential for anchorage, the uptake of water and nutrients and the storage of energy (carbohydrates) for the future growth and function of the tree.
2.2.2 Roots can be damaged by physical severance or wounding (e.g. following excavation of the soil) which can lead to the development of decay and a decline in vitality and/or instability. Raising soil level effectively buries tree roots at a depth where suitable conditions for growth are less available. Toxic materials discharged into the soil (such as cement based aggregates, fuel and chemicals) can lead to root death and dysfunction. Soils can be compacted to levels inhospitable to tree growth with even a single pass of machinery, regular pedestrian traffic or the storage of plant and materials. Relieving compaction can be problematic and may require costly remedial works. Changes in drainage/water levels can also have significant long term impacts for tree health.
2.2.3 The effects of these incursions may take many years to manifest, with a resulting decline in amenity value and potentially the death or failure of the tree. It should be noted that older trees are particularly sensitive to damage and changes in conditions.
2.2.4 The Root Protection Area (RPA) is a notional area considered to be the minimum zone that must be protected to avoid any adverse impacts on retained trees. This area is deemed to be particularly important for tree stability, growth, function and health. However roots may extend far greater distances, with the distribution of the root system relating directly to the availability of suitable conditions for growth (namely oxygen, water and nutrients). It is generally accepted that tree roots are predominantly located in the upper 1000mm of soil; however roots may develop at deeper levels where conditions allow.
2.2.5 Root Protection Areas are calculated as per BS5837: 2012 Annexe C, D and Section 4.6.
2.2.6 The RPA of the existing tree stock is an important material consideration when considering Site constraints and planning development activities. The RPA of significant trees on Site is shown on the Tree Survey Plans included as Appendix A.
2.2.7 The default position must be that all development, including any associated services will occur outside the Root Protection Areas of retained trees. Where this is unavoidable it may be appropriate to use special measures to install structures, services or surfacing within RPA’s which allow the protection of roots and soil structure which are essential for tree growth and keep any incursion to a minimum.
2.2.8 Further steps to improve or increase the useable rooting area available to the tree may also be required.

2.3 Soils
2.3.1 On shrinkable clay soil tree growth can lead to the differential movement of structures as moisture is removed from the soil during the growing season. Soils must be carefully assessed and any foundations must be installed following the recommendations of NHBC Standards Chapter 4.2: Building Near Trees (2008) to avoid potential future damage. Where trees which predate existing structures are to be removed this can result in heave as the soils re-wet. The advice of a suitably qualified engineer must be obtained to inform any potential issue of heave. Specific advice in relation to this issue is beyond the scope of this report.
2.4 Above ground constraints
2.4.1 Tree stems and branches can restrict available space on Site. Damage or wounding (including excessive pruning) can significantly reduce the amenity contribution of the tree and may lead to the development of dysfunction and decay with significant long term implications for tree health. The future impact of existing trees should be carefully considered, including individual species characteristics (such as potential future size, fruit fall, shade etc.) and how the tree will interact with any proposed development and future land use. Annual tree growth can lead to direct damage if stems/branches (or roots) come into physical contact with structures and this must also be taken into consideration.

3. Field Observations
3.1 The Site:
3.1.1 Calverley Grounds is a public open space and landscaped parkland in the centre of Tunbridge Wells. This report focuses on land on the western side of the Site and is defined by the area covered by the Tree Survey Plan included as Appendix B. The Site itself is bordered to the west by a multi-level car park and Mount Pleasant Avenue beyond which lies the Mount Pleasant Road which features the Great Hall Arcade and other retail outlets. To the north the Site is bordered by the Hotel du Vin and AXA offices located on Crescent Road. To the south of the grounds are the terraced residential properties on Mountfield Road and Mountfield Gardens. To the east the Grounds continue as formal parkland featuring sports pitches
3.2 The Trees:
3.2.1 Trees within Calverley Grounds are typically individual or group plantings in open parkland surrounded by lawns or located in groups around the edges or within a central section of the Site.
3.2.2 The Site features a fairly diverse range of tree species including both broadleaved trees such as horse chestnut, lime, beech and oak along with conifers such as cypress, Scots pine and western red cedar.
3.2.3 Age ranges are equally diverse with a number of significant mature and early mature trees along with some semi mature specimens with good future potential. Young and newly planted trees are not well represented. The majority of trees on Site are in generally fair to good condition however a small number of trees have significant defects. Where trees have significant defects or require remedial works this has been noted on the survey schedule included as Appendix A of this report.
3.2.4 A number of trees have surface roots and buttresses with impact wounds likely sustained from the ride on lawn mowers maintaining the grass. Ideally, mowers should avoid cutting the grass around raised surface roots and buttresses. Mulch can also be usefully applied to restrict grass and weed growth and too avoid the requirement for mowing.
3.2.5 Horse chestnut trees across the Site also typically have bleeding lesions associated with bleeding canker (Pseudomonas syringae pv aesculi) which can have a negative impact on the trees vitality and should be monitored into the future to assess how they respond to this issue.
3.2.6 Some trees have been heavily pruned in the past such as T4 a horse chestnut near the southern boundary of the site. Two Atlantic cedars T82 and T83 have been subject to storm damage resulting in the loss of limbs and significant remedial works (particularly for T83).
3.2.7 The red oak T87 has dieback in its canopy which is likely to be associated with the presence of a root decay fungus (Collybia fusipes) which is present at the base of the tree. This fungus can lead to canopy dieback in its later stages of the infection process and is thought to be a potential causal factor in the development of ‘oak decline’.
3.2.8 In the central western section of the Site to the north of the toilet block, an area of sycamore, oak and ash woodland has developed, trees in this location have developed as a group and generally consist of individuals of relatively poor quality. One prominent mature oak is located to the west of the group which is heavily covered with ivy. To the east of this group is an unmaintained Lawson’s cypress hedgerow feature with closely planted trees. The area around these trees has been subject to littering and vandalism. Trees growing around the toilet block and adjacent structure are touching the roof in a number of places and need to be pruned back or removed to prevent damage.
3.2.9 Further west is located an ornamental group of Japanese maples, yew and other small trees interspersed with shrub planting.

3.2.10 To the northwest a dense linear group of Norway maple, horse chestnut and sweet chestnut forms the western boundary of the parkland adjacent to the pay and display car park. These trees are encroaching on the car park to the west. Access was limited due to the density of the vegetation however a small clump of Japanese Knotweed was identified to the east of T51 and T52. This is a Schedule 9 plant under the Wildlife and Countryside Act 1981and will require careful management. The advice of a suitably qualified and experienced ecologist is recommended to inform the management of this issue. To the east a linear group of good quality Scots and Austrian pine are located in an open grassed area. Further east a mature beech and adjacent copper beech with compression forks are sited on either side of a footpath. These significant trees are recommended for remedial works to reduce the potential risk associated with limb failure due to this common structural weakness.
3.2.11 In the central area of open parkland high quality giant sequoia, lime and birch are located along with a Persian ironwood which has been planted as a memorial tree and has memorial tags attached to its outer branches. Further west is a group of red oak, which form a prominent feature within the Site.
3.2.12 To the south and south west the Site is bordered by linear tree groups of generally moderate condition. These trees help to screen views of the car parks, shopping and residential areas as viewed from the park. A number of trees have surface roots which have developed within the lawn outside of the formal planting beds and these have often sustained impact damage or root severance associated with the maintenance of the lawns. Many of these trees have been heavily pruned in the past where they are located in close proximity to residential properties.
3.2.13 Three trees were assigned to the Category A and these trees were considered to be of high quality, which are likely to make a significant contribution to the site for at least 40 years. .
3.2.14 Thirty five trees or tree groups were described as Moderate quality (BS5837 Category B). These trees have at least 20 years of future contribution to the site if they are to be retained.
3.2.15 Fifty four trees were assigned to Category C. These trees were described as of relatively low quality due to their structural form, physiological condition or suitability to their location. Category C trees are likely to provide at least ten years future contribution to the site.
3.2.16 Three trees were assigned to Category U, and trees of this quality will provide less than 10 years future contribution to the site and may need to be removed due to their condition or current location in the context of the site.
3.2.17 Tree works have been recommended for trees were appropriate based on sound arboricultural management in the context of the current land use of the site and these are shown on the schedules included as Appendix A.

4. Tree Related Constraints and Opportunities 4.1.1 The Tree Constraints Plan included as Appendix B show the area of constraint associated with the trees on
Site. As identified within the drawing key, the green shaded area shows the extent of tree canopies and the dashed black line is indicative of the root protection area (RPA), which is the nominal area of tree roots which are generally considered essential to tree health and function. Roots are likely to extend outside of this point but beyond the RPA extent tree roots are not considered a significant constraint.
4.1.2 The default position is generally that all new features and associated works be located outside of these areas, where trees are to be retained. The area outside of these points is not significantly restricted by constraints associated with the trees and this represents the initial developable space for the Site.
4.1.3 Particular care is necessary in association with trees located outside of the Site boundary (owned by third parties) but where branches or roots are likely to extend within the Site. The LPA are likely to expect that third party trees are not significantly damaged by any proposed development works within the Site when considering planning applications. Common law rights to prune back overhanging growth to the boundary are well established but liability is likely to result for any resulting loss or damage should a tree be left in an unstable state. Any arising’s also remain the legal property of the tree owner. For these reasons arboricultural advice must be obtained prior to any works which could significantly impact on trees located outside of the Site boundary.
4.1.4 In the context of Calverley Grounds the most significant off-site trees are G93 and G94, groups of mature lime, oak and sycamore located beyond the north western boundary of the site within the AXA offices site. The RPA of these trees is likely to incur a considerable distance inside the Site boundary and must be carefully considered in relation to any proposed development in this area.

4.1.5 Memorial trees and those with significant cultural status are likely to be highly valued and must be retained where ever possible. T78 (Persian ironwood) is understood to have been planted as a memorial and this tree will require careful consideration.
4.1.6 Where significant development works are required within large sections of the canopy or RPA of trees this is likely to necessitate their removal and this can be justified where trees are of low quality or where the retention of trees is not feasible in relation to the design proposals and the benefits of the development outweighs the potential impact on tree cover. In such circumstances robust mitigation planting is typically required to ensure that continuity of tree cover is maintained within the Site and to off-set any negative impact on local amenity. It must be noted that new trees which are typically planted as ‘standards’ or ‘heavy standards’ will not be of equivalent size or amenity value to existing semi mature to mature trees which may need to be removed. Where possible the retention of existing trees which will be suited to the context of the proposed development can help maintain a level of maturity for the Site.
4.1.7 In some cases moving existing trees to new locations within the Site (or temporarily relocating them prior to replanting back on Site) can help to ensure reasonable space for the proposals whilst allowing the retention of significant trees. Moving trees, particularly larger specimens, requires a considerable commitment to aftercare to help trees re-establish a sufficient root system to maintain physiological function. Where feasible tree root ball preparation should be carried out as early as possible in advance of tree moving works. A number of trees within Calverley Grounds could feasibly be moved if desired. AECOM and its partners can assist with tree moving projects where required.
4.1.8 In some cases it can be acceptable to install structures, access routes and services or other features using specialist methodologies which do not require significant excavation and which can ensure that suitable conditions for tree growth and function are maintained. The advice of an arboriculturist should be obtained to inform the design process where these issues arise. New areas of hard surfacing or building footprints should not generally occupy more than 20% of the RPA of a retained tree as set out in Section 7.4.2.3 of BS5837:2012, however this is a recommendation only and in our experience it is often feasible to install appropriate new hard surfacing or structures within a greater proportion of the RPA provided sufficient justification is given.
4.2 Tree Categorisations as per BS5837:2012
4.2.1 Trees on site have been assigned to a quality category as per BS5837:2012 which relates to their arboricultural, landscape and cultural/conservation value.
4.2.2 Category C trees as shown by a grey canopy outline. This means they are of relatively low quality and would not normally be considered a significant constraint to future development. However these trees may still provide some useful value to the site and should be considered for retention where they do not pose a significant constraint to the proposals.
4.2.3 Category B trees (blue canopy outline) are described as being of moderate quality and it is generally desirable to retain trees of this standard and incorporate them within the design proposals wherever feasible.
4.2.4 Category A trees (green canopy outline) are classified as being of high quality and trees of this nature should be retained and incorporated into the design due to the high level of benefits they provide.
4.2.5 Category U trees (red canopy outline) are trees with less than ten years reasonable useful life expectancy or those in such poor condition that they should be removed regardless of any development activity. Trees of this nature represent no constraint to development.
4.2.6 In general this means that category C trees and groups of relatively low value can be removed to facilitate the development, but where this is not necessary they can be usefully retained in situ.
4.2.7 Category B (blue) and A (green) trees should ideally be retained and included and afforded sufficient space within the design. It may be feasible to remove some category B trees and in exceptional circumstances, category A trees, however this is likely to require significant justification and mitigation (in the form of new tree planting).

4.3 The Benefits of Trees
4.3.1 Well placed trees are aesthetically pleasing, add instant maturity to a site and can attract investment and higher property values along with a host of other health, well-being, amenity and biodiversity benefits. The value of existing trees must be carefully considered, established trees are not always easily replaced and the requirements for new tree planting and suitable aftercare can be considerable, particularly if larger planting stock is utilised.
4.4 The Future Impact of Trees
4.4.1 The future impact of trees on site must be considered in relation to any proposed development. Some trees may be suitable for retention in areas of open space but are unlikely to be suited close to new structures due to their future size, and structural characteristics. Trees to be retained should be afforded suitable space to allow for their likely future growth to prevent significant issues such as direct damage where branches or stems come into contact with structures, causing physical damage.
4.4.2 Many of the trees are deciduous, and as such will drop leaves each autumn. This can be an issue for gutters and new structures in close proximity to trees, particularly where a canopy is likely to overhang the structure in the future. Gutters and structures close to trees should therefore be constructed with this in mind. The positioning of gutters, the use of Gutter Guards or equivalent methods along with regular periodic maintenance can be used to reduce the ingress of leaves into guttering systems.
4.4.3 Fruit bearing trees (including plums, crab apples and cherries) can cause slip hazards on paths and may attract wasps in the summer months and therefore footways and car parking is not generally appropriate in close proximity to these species.
4.4.4 Species such as lime and sycamore frequently harbour a high volume of aphids, sap sucking insects which excrete a sugary liquid known as honeydew. This can create sticky patches on surfaces and vehicles below the canopy and may lead to the development of sooty moulds. These issues could lead to future pressure to remove the trees where they could overhang structures or car parking. Honeydew does not generally cause damage and can be cleaned with warm soapy water.
4.4.5 Trees generally cast shade in an arc from the North West to due east (as the sun tracks from east to west on a southerly orientation); an indicative shading arc can be produced by plotting a segment with a radius equivalent to the height of the tree as per BS5837: 2012 Section 5.2.2. Shade may be beneficial in some areas (particularly with regard to projected temperature increases in relation to climate change), however where heavy shade affects areas it may lead to significant future pressure for tree removal which would render the long term future of trees potentially untenable.
4.4.6 AECOM can provide drawings to demonstrate the future typical canopy development and future approximate shade (based on approximate ultimate tree height) upon request. This information is intended as a guide only and is based on general assumptions on the likely average growth and ultimate height and canopy spread of individual tree species.
4.5 Tree Protection During Construction
4.5.1 Trees to be retained in close proximity to areas of development activity, including areas for new surfacing, structures, services, storage landscaping and access will need to be protected to ensure they are not damaged. This is generally achieved with the use of robust, immovable temporary tree protection fencing to prevent access within the RPA or canopy spread of trees. Where access is unavoidable alternative protection arrangements such as ground protection, sufficient to protect the structure of the soil from compaction, and /or access facilitation pruning to ensure a reasonable clearance for operations is provided may be required. The advice of an arboriculturist should be sought to inform this assessment.
4.6 Tree Planting
4.6.1 Where trees are to be removed due to a conflict with the proposed design, mitigation planting is likely to be required to ensure a continuity of tree cover within the site and to address any negative impact on local amenity. Consideration should be given to the reasonable provision of space and suitable un-compacted soil volumes for new tree planting to off-set any necessary tree loss.
Calverley Grounds – Baseline Arboricultural Report
10
4.6.2 New planting should ensure that a high degree of species diversity is achieved to enhance resilience against a changing climate and new pests and diseases and tree species must be selected which will be suited to the likely future conditions for the Site.
4.6.3 Areas for new planting should be considered at an early stage and where possible tree planting soil volumes should be protected throughout the construction stage so that good conditions for new tree planting are available following completion of the works. Where this is not possible, remedial works to ameliorate the structure of the soil or the importation of new soil is likely to be required.
5. Summary and Recommendations 5.1.1 Calverley Grounds contains a strong population of significant trees which provide a broad range of benefits
to the community.
5.1.2 The Tree Constraint Plans demonstrate the quality of individual trees and groups and the spatial constraints associated with them.
5.1.3 Design development must consider the constraints associated with the trees and particularly those Category B (blue) and Category A (green) trees which are considered to be of the greatest value and are a material constraint on development. Where ever possible trees of this quality are to be retained and protected.
5.1.4 Should it be necessary to remove trees of this quality, this will require robust justification and is likely to require the benefits of the development to outweigh the loss of the trees in the planning context.
5.1.5 A number of higher quality trees and a memorial tree could potentially be moved and relocated elsewhere on the Site (or be temporarily stored and replanted following completion of the works).
5.1.6 Lower quality Category C (grey) trees should be retained where they do not conflict with the design proposals, but are unlikely to be a significant constraint to development and their loss can generally be mitigated with high quality new tree planting within the Site.
5.1.7 Where trees are to be retained, they must be afforded sufficient space and protection throughout the development phase (typically requiring an exclusion zone around the tree, its canopy and RPA). The design must also account for the likely future growth and impact of the trees in the new context of the site.
5.1.8 Tree removals can be mitigated with appropriate new tree planting which represents an opportunity to increase the diversity and resilience of the local tree population and to ensure well placed tree cover for the future amenity of the Site
5.1.9 Outline design proposals should be discussed with an arboriculturist to review the likely impact on the significant trees and to identify any opportunities for mitigation where appropriate.
5.1.10 Following design freeze, the finalised layout should be subject to an Arboricultural Impact Assessment to identify the direct and indirect impacts of the final scheme, to allow the identification of suitable measures to ensure trees to be retained are protected and to set out appropriate mitigation as required. This is typically the minimum requirement for planning purposes and would be submitted in the form of a report in support of a planning application.

5.2 Considerations:
1) Tree owners/managers have a legal duty to prevent foreseeable harm. It is generally accepted that this duty can be fulfilled by undertaking proactive inspections of significant trees to identify obvious defects and by taking appropriate remedial action or gaining further advice as appropriate. This survey is primarily for planning purposes, focusing on the quality and benefits of the trees and is not specifically designed to assess the safety of trees on Site. When obvious issues have been identified recommendations will be included on the schedule.
2) Under the Construction (Design and Management) Regulations (2015) developers and contractors have responsibilities for health and safety as a result of their actions. Should trees be left in an unstable or hazardous condition the Health and Safety Executive (HSE) could seek to prosecute those responsible along with the potential for further Civil claims for damages.
3) No information has been made available in relation to any statutory tree protection, including Tree Preservation Orders (TPO) or Conservation Area designations. Prior to any tree work this situation must be confirmed with the LPA. Full planning consent overrides the requirement to provide notice or apply for consent for tree works.
4) Where more than 5m3 of timber is to be felled within a calendar quarter a felling licence may be required from the Forestry Commission unless an agreed exception applies. The requirement for a felling licence does not apply to tree works on designated public open spaces and therefore this is not likely to be applicable in this instance. Full planning consent also supersedes the requirements of a felling licence.
5) Full consideration must be given to the presence of species protected under the Wildlife and Countryside Act (1981 - as amended), the Countryside and Rights of Way Act (2000) and the Habitats Regulations (2010 – as amended); in particular, the presence of bats and nesting birds. It is recommended that wherever possible, significant tree / hedge works take place outside of the typical bird nesting season of March to September.
6) Any tree surgery recommendations contained within this report are to be undertaken in accordance with BS3998: 2010 Tree work – Recommendations (BS3998) by suitably qualified and insured contractors. Significant pruning works are best undertaken when trees are dormant or outside periods of high functional activity to reduce the overall impact on energy available to the tree for growth and processes. In general the optimum period for works is between November to February and July to August (subject to the presence of protected species) when the tree is less active and better placed to respond to wounding and a reduction in leaf area.
7) Fieldwork survey information is subject to seasonal/access constraints.
8) The Local Planning Authority (LPA) may make conditions relating to tree protection which could include compliance with an Arboricultural Method Statement. Breach of conditions may result enforcement action.

Young (Y): Newly planted tree 0-10 years. Semi-Mature (SM): Tree in the first third of its normal life expectancy for the species (significant potential for future growth in size). Early Mature (EM): Tree in the second third of its normal life expectancy for the species (some potential for future growth in size). Mature (M): Tree in the final third of its normal life expectancy for the species (having typically reached its approximate ultimate size). Over Mature (OM): Tree beyond the normal life expectancy for the species. Veteran (V): Tree which is of interest biologically, aesthetically or culturally because of its condition, size or age.
Structural condition
Good: No significant structural defects. Fair: Structural defects which can be resolved via remedial works. Poor: Structural defects which cannot be resolved via remedial works. Dead: Dead.
Physiological condition
Good: Normal vitality including leaf size, bud growth, density of crown and wound wood development. Fair: Lower than normal vitality, reduced bud development, reduced crown density, reduced response to wounds. Poor: Low vitality, low development and distribution of buds, discoloured leaves, low crown density, little extension growth for the species. Dead: Dead. Fair/Good = Indicates an intermediate condition. Fair – Good = Indicates a range of conditions (e.g. within a group).
