1. REPORT DETAILS 1.1. Arboricultural Implication Assessment (AIA)
An Arboricultural Implication Assessment (AIA) is a term used to describe a specific type of tree survey which examines the relationship between existing trees and proposed features or processes (such as buildings, roads, specific works etc.) The study describes how the trees and features will interact and influence each other both in the present and in the future. Such studies are commonly used to determine whether a proposed development (or its operations) will adversely affect established trees and whether these trees will be a cause of nuisance to the proposed development. Similar terms used to define this type of report are 'Arboricultural Impact Appraisal' or 'Arboricultural Impact Study'.
1.2. Terms
The following abbreviations may be used within this report:
• TPO = Tree Preservation Order
• RPA = Root Protection Area
• BS5837 = BS5837:2012 Trees in Relation to Design, Demolition and Construction - Recommendations.
1.3. Limitations

2. THE SITE
2.1. Site Description
This site is located on the northern fringe of the village of Marden, approximately 5 miles north of Hereford. It is an agricultural packaging/processing commercial site comprising of a number of buildings, a large number of caravans, open spaces, car parking areas and access roads. Access to the site is made to the west via Orchard Green which links directly to the A49.
2.2. Proposed Operations
The proposed operations for this site requires the: 1. Removal of trees, scrub, hedges etc. 2. Establishment of new road access to the east. 3. Construction of new dwellings and highways. 4. Establishment of new footpaths, landscaping, fencing etc.
2.3. Tree Survey
A Pre-Planning Tree Survey was carried out for this site during June 2017 (see document no: DLA/TS1535/2). All tree identification numbers used within this report correspond with those contained within the tree survey schedule and associated drawing.

3. INTRODUCTION
3.1. AIA Objectives
• To assess the areas located on this site where proposed works are to be carried out in close proximity to established trees.
• To determine whether the proposed works can be carried out successfully without adversely affecting the trees both in the long and short-term.
• To suggest ways to mitigate any conflicts that may arise between the trees and the proposed operations and to offer recommendations relating to the protection of the trees during these works.
3.2. Items for Consideration.
Trees and development located within close proximity to each other can influence each other in a number of ways. The following items are normally considered during arboricultural impact studies:
• Root disturbance caused by demolition, excavation & construction (of buildings and roadways).
• Location of service runs, works buildings & materials storage.
• Changes in levels & surface types.
• Sunlight shading of exterior amenity areas (such as gardens, patios, etc).
• Physical encroachment by roots, tree stem & branches.
• Allowance for future tree growth.
• Health, safety and nuisance items (such as leaves, fruit and insects). 3.3. Guidance whilst assessing trees in relation to development.

4. ANALYSIS 4.1. Introduction
This section (4) identifies and describes those particular trees which are considered as being in potential conflict with the proposed operations. Mitigation is included where appropriate and shown highlighted. The following section (5) summarises these conflicts and includes any suggestions for mitigation where appropriate.
4.2. Trees for Assessment
This assessment includes all trees located within influential distance to the development area which includes a number of trees located within adjacent properties. Only trees identified within the pre-planning tree survey as being of the BS5837 category grade ‘A, B and C’ are assessed. Category U trees are identified below.
4.3. ‘U’ Category Trees for Removal
These are trees identified within the tree survey as requiring removal due to Health & safety reasons or because their condition is of such a state that they are deemed to have less than 10 years of life expectancy. 1. The following trees are identified as Category U.
T27, T28, T29, T31, T32, T41, T46, T57, T63, T77, T79 and T94.
4.4. Direct Tree Losses
Direct losses relate to trees which fall directly within (or very close too) a construction area such as a proposed building footprint or a proposed road and which are considered to be unretainable. This also includes trees which are considered unretainable with respect to existing building demolition.
1. The following trees fall directly within, or are very close to, the footprints of
proposed buildings, roads, footpaths and other structures. These trees are considered unretainable in light of the required construction works.
G2, T3, G4, T5-7, G8, T11-19, part G20, T24, T29, T31, T38-39, T47, T53-54, T56, T58-59, G60, T61-62, T65, H66, G67, T68, G70, T71, T75-76, T85, T87, part G89, G91, T92, T94-96, H97, part G98, T104-105, T108, G109, T110, T116, H127-128, H131 and H133.
2. Additionally, the following Category C trees which are predominantly isolated or are of small size, can be easily replaced as part of the landscaping plan.
T10, G30, T64, T69 and H129.
Arboricultural Report No: DLA/1535/AIA/1 Page No: 7 Chris Skellern 2017
3. The total tree losses required by the development (not including the U
Category trees) are approximately 150 trees (which includes an estimated tree group count but not including hedgerows).
4. The majority of tree losses apply to the linear groups and hedgerows located centrally within the site. A number of individual trees close to the existing buildings to the north need removal for new road/footpath access. Other losses apply to boundary trees located close to new buildings/roads.
Please note that the trees identified under this heading are not assessed further in any of the following categories. Refer to the AIA drawing for the location of all trees to be removed.
4.5. Works within Root Protection Areas
Root protection Areas (RPA) are necessary to ensure that soil compaction does not take place over tree roots. All remaining trees (from 4.4) which are considered retainable were assessed in relation to any ground works which may need to breach the recommended protective distance and possibly be a cause of root damage through physical contact or through soil compaction. 1. The following tables lists the trees which have their root protection areas
overlapping an adjacent proposed road or structure. The table lists the actual area of overlap and its percentage of the trees total RPA. Refer to the AIA drawing for the reference (Ref) locations.
Ref Tree Description RPA
Overlap m²
Percentage of Trees
RPA
R1 T42 RPA overlaps footpath to the west. 5.00 m² 3.5%
R2 T55 RPA overlaps footpath to the north. 3.7 m² 3.3%
2. R1 results in a 3.5% of RPA loss to T42 (a category B Norway Maple tree).
R2 results in a 3.3% RPA loss to T55 (a category B Oak tree). These losses are considered small and only affect the outer edge of the RPA’s. These losses can be offset by increases in other directions.
4.6. Demolition
1. No demolition works are required within the proximity of any retained tree RPA.
4.7. Changes in Levels
1. No significant changes in ground levels are required within any of the retained tree root protection areas.
Arboricultural Report No: DLA/1535/AIA/1 Page No: 8 Chris Skellern 2017
4.8. Changes in Surfaces
1. With the exception of the trees detailed in 4.5 which have footpaths within their RPA’s, all remaining surfaces within RPA’s will remain as existing landscape. However, in some cases the existing soft surface will need to be replaced with formal lawn; so, these works have the potential for soil compaction and require controls.
4.9. Services
1. New service runs will follow the existing/proposed driveways and be located outside all tree root protection areas.
4.10. Works Buildings and Material Storage
1. The works buildings and material storage areas will be located within planned open spaces outside of all tree root protection areas.
4.11. Access
1. Site access will issue from the new proposed road junction. No access will be required within any designated tree RPA.
4.12. Obstruction of Sunlight
Trees can be a cause of nuisance when they cause excessive shade for long periods of time to recreational areas such as gardens. It is important, therefore, to ensure that a reasonable level of shade-free garden/patio space is available for use. If such shade-free space is not made available in a proposed site layout, then protected trees may become a target for removal or pruning by the home owner. BS5837:2012 states in section 5.3.4 (2) that “Open spaces such as gardens and sitting areas should be designed to meet the normal requirement for direct sunlight for at least a part of the day”. And the BRE publication Site Layout Planning for Daylight and Sunlight states that “If the whole of the garden is shaded by trees for a lengthy period of time in summer, the garden is probably too shady”.
1. This assessment was carried on all proposed residential gardens and the
adjacent trees. Gardens which are deep within the development or which are far from any significant trees were ignored.
2. Tree group G101 (located on the eastern site boundary) will be a cause of shade to the rear gardens of the adjacent dwellings to its west early in the morning for all days of the year. However, these gardens will be shade free for the remaining part of the day throughout the year as the suns position in the sky moves westward causing the tree shadows to move eastwards away from the site.
Arboricultural Report No: DLA/1535/AIA/1 Page No: 9 Chris Skellern 2017
3. All remaining trees on this site which are to be retained, are either too far from the development to be an issue or are of a very small size to offer any significant interference.
4. I consider that the tests suggested by BS5837:2012 and the BRE document (Site Layout Planning for Daylight and Sunlight) are not exceeded by this scheme.
4.13. Existing Canopy Extents
Assessing a scheme against existing tree crown extents is necessary to ensure clearances are achievable over certain structures and highways etc. Canopies overhanging a dwelling are likely to become a nuisance where they can physically damage the property, cause noise through contact in windy conditions and drop debris onto rooftops. 1. No canopies from existing trees which are to be retained will overhang any
proposed buildings.
4.14. Future Growth Assessing for future tree growth is normally necessary to ensure an increase in tree height or canopy spread will not create a future nuisance which may in turn become a requirement for tree pruning or removal. 1. No canopy future growth from existing trees which are to be retained will
overhang any proposed buildings.
4.15. New Planting The positions of all new tree planting should be carefully planned to ensure the trees can grow fully into maturity without requiring major pruning works. Consequently, new stock should not be positioned close to buildings, windows and either subterranean or aerial service runs. It is also important to ensure that existing trees are provided with sufficient room for canopy expansion without major pruning works being required.
1. All new planting will be located clear of the proposed buildings and services
to ensure they can mature fully without the need for pruning.
4.16. Leaves
Roads, footpaths and buildings in proximity to trees will normally suffer the nuisance of falling leaves from deciduous trees. Leaves rarely fall in a vertical direction but tend to be carried by the breeze, sometimes to great distances. 1. Some leaf accumulation is expected to drift over the new building and
garden areas. This will occur predominantly during autumn/winter when the deciduous trees drop their leaves.
2. This is not considered to be a major issue due to the distances of the existing trees.
Arboricultural Report No: DLA/1535/AIA/1 Page No: 10 Chris Skellern 2017
4.17. Fruit and Seeds
The fruit of trees can sometimes be a cause of nuisance on footpaths where the soft flesh can cause an unsightly appearance and slippage to pedestrians.
1. The existing trees species are not considered to be a potential nuisance
with regards to problematic fruit & seeds. 4.18. Honeydew
Honeydew is a sugary secretion produced by sap sucking insects. Such a secretion can cause a sticky deposit to build up on the surfaces of cars, footpaths and other items located below the canopy of the tree. Most trees indirectly produce some level of honeydew. However, certain species such as Lime, Maple (Sycamore) & Oak can produce high quantities which can be a cause of nuisance. Deposits on hard surfaces will be most noticeable during late summer when rainfall is scarce and insect activity peaks. Its effects would be noticed as a slight sticking of a person’s foot whilst walking over the deposit; it is not normally a cause of slippage.
1. The existing trees species which will overhang proposed footpaths are not
considered to be a potential nuisance with regards to honeydew.

5. SUMMARY
5.1. Introduction
This section assesses the implications of any major conflicts discovered in the previous section. Suggestions for mitigation may be included where appropriate.
5.2. Tree losses
The required tree losses are predominantly within the central site and include several groups and parts of hedgerows. Many of these trees are positioned upon ‘bunds’ which require removal for the development. The above losses can be mitigated with replacement stock as part of the proposed planting scheme.
5.3. Works within Root Protection Areas (RPA)
The two category B trees (T42 – Norway Maple and T55 – Oak) which are planned for retention have a small part of their RPA overlapped by adjacent proposed footpaths. The loss of RPA is small, amounting to 3.5% and 3.3%. The overlap also affects only the outer edge and doesn’t reach further than 1m from the RPA extent. Such a small loss can be mitigated by increasing the RPA in other directions which is possible for these trees.
Arboricultural Report No: DLA/1535/AIA/1 Page No: 12 Chris Skellern 2017
6. RECOMMENDATIONS
6.1. Site Specific Recommendations
1. To compile all details regarding the tree protection and any special controls within a Tree Protection Plan and Arboricultural Method Statement for use on-site by the works contractors. Such a statement would include a time-table for implementation of tree protection measures and detailed information relating to tree protective fencing (specification & distances). Also, information relating contingency plans (for items such as accidental collision with a tree or chemical spillage over rooting zones) should be included.
6.2. General Recommendations
1. To ensure that all tree protection is established prior to any construction activities including material storage and excavation.
2. To ensure that all contractors are informed of the reasons behind the tree
protection measures.
3. To ensure that any roots encountered during the construction works, with diameters exceeding 10-15mm, are pruned correctly with proper sharp pruning tools.
4. To avoid changing levels over tree protection zones except for ‘dressing’
purposes where such applications should be limited to a maximum depth of 60mm for topsoil and 100mm for wood/bark mulch.
5. I recommend that this site be properly supervised by an appropriately qualified
arboriculturist to ensure that all protection matters relating to the trees are observed and to be available should any unforeseen problems arise.
6. It is recommended that all tree maintenance works be carried out by a suitably
qualified and insured arboriculturist to the recommendations detailed within BS3998:2010 Tree Work Recommendations.
