Arboricultural Report & Method Statement Hallam, Ashmansworth, Newbury, Berkshire September 2016

Page: 2

Instructions

We are instructed to provide an arboricultural report (Arboricultural Impact Assessment) and

method statement (AMS) in connection with an application for planning permission at the

above site. These proposals have been prepared in accordance with the recommendations of

BS5837:2012, other relevant standards, codes of practice and government circular advice.

Implementation

The AMS must be read in conjunction with the tree protection plan (AMS1). Both will be

available on site for the use of all personnel, contractors and sub-contractors involved in site

operations. All persons involved in site operations will be made aware of the AMS and the

importance of adhering to its requirements and the protection of trees at the site. No operations

within the RPA of retained trees will be permitted unless specifically allowed in the AMS or any

subsequent revision agreed by the local planning authority.

1 Tree Survey

1.1 I re-surveyed trees at the above site on 22 September 2016. This survey was

undertaken in accordance with the recommendations of BS5837:2012 'Trees in relation

to design, demolition and construction - Recommendations'1. The tree survey and

constraints plan (TCP) is attached as AMS1 and tree survey schedule as AMS5. The

trees are located as indicated on the attached plan.

1.2 The attached tree survey (AMS5) indicates the species, size and condition of the

individual trees on the application site. The tree survey and constraints plan (AMS1)

numbers the individual trees and corresponds to the tree survey schedule (AMS5).

Additionally, the trees have been colour-coded on the plan to indicate their categories

in accordance with the standard. The sub-categories in the tree survey schedule

provide a qualitative assessment and reason for their inclusion in a particular category.

1.3 Immediately adjacent to the northwest boundary is a line of mature lime trees (trees 1-

8) of up to 20 metres in height and crown spread radius of 4.5 to 5 metres. They are

regrown pollards and, with the consent of the local planning authority, have now been

crown reduced to their current dimensions.

1.4 I understand the site is within a conservation area and the trees are therefore protected

by conservation area legislation.

2 Proposed Development

2.1 I have seen the plans and various documents accompanying the current application

prepared by Fowler Architecture and Planning. To assess the effect of these proposals

on existing trees I have applied the criteria of BS5837:2012 and my own experience in

the retention of trees on development sites. The trees that would be retained and

removed are indicated on the tree constraints plan (AMS1) which is an extract of the

application plan.

1 BS5837:2012 Clause 4.5 - Tree categorization method


Page: 4

2.2 The root protection area (m2) (RPA) for individual and groups of trees has been

calculated using the tree survey data in conjunction with the advice of the Standard2.

Where tree root growth may have been restricted by pre-existing site conditions, the

shape of the RPA has been adjusted to reflect the most likely rooting pattern and

distribution. In this case the overall size of the RPA has been maintained.

2.3 The RPA is the prescribed minimum area (m2) that should be left undisturbed around

each individual or group of trees. The dimensions of the RPA are plotted as a circle on

the tree constraints plan (AMS1). The plan indicates both the above and below ground

constraints and has been used as a design tool in preparing the proposed site layout.

2.4 I note the footprint of the proposed dwelling has been reduced from the previous

permitted scheme and that there would now be less build within the RPA of the lime

trees (trees 6, 7 & 8). Furthermore, the overall size of these trees has been reduced,

providing a more open area and more light to the front of the house. In my assessment,

all the trees at the application site and included in the tree survey would be retained,

comply with the recommendations of the Standard and, provided they are properly

protected during development, would not be adversely affected by the proposed

development.

3 Structures

3.1 Where structures or hard surface areas are within the RPA of retained trees they will

be constructed to recognised standards and good arboricultural practice. Every

precaution will be taken to ensure all parts of the retained trees are properly protected

to ensure they will not be directly or indirectly damaged by the construction.

Arboricultural site supervision will be provided where appropriate.

3.2 Special Foundations

Where the proposed building would be within the RPA of retained trees (trees 6 – 8),

to avoid damage to the roots, as permitted previously, it will be constructed as a surface

raft supported by pads or piles as appropriate and designed to the recommendations

2 BS5837:2012: Cause 4.6 - Root protection area


Page: 5

of the Standard3. The foundations will be engineer designed and the specification and

construction details submitted for the approval of the local planning authority prior to

construction.

3.3 Access and Hard Surface Areas

Where the access drive, footpaths, parking spaces or other hard landscape features

are within the RPA of retained trees they will be constructed in accordance with the

recommendations of BS5837:20124 and Arboricultural Advisory and Information Service

APN125.

3.4 Where the access drive, and parking would be within the RPA of retained trees,

excavation will be restricted to the removal of the vegetative/humus layer only, or the

utilisation of any existing hard surface areas. The new surface will be a no-dig

construction using a three-dimensional cellular confinement system. The wearing

course for the access drive and parking spaces will be of a type recommended in the

Standard6. Only light hand-operated compaction machinery will be used within the RPA

of retained trees. Edge supports will be treated pegged boards founded at existing

ground level on the geotextile membrane (AMS3 - Three Dimensional Cellular

Confinement System - example).

3.5 Footpaths.

Any footpaths within the RPA of retained trees will be a two-dimensional surface

construction founded on a geotextile membrane. The wearing course will be to the

design recommendations of the Standard7. Edge supports will be appropriate to the

type of hard surface and recommendations of the Standard8.

3.6 Hard surface areas within the RPA are shown on the attached tree protection plan

(AMS1).

Page: 6

4 Services and Drainage

4.1 Where possible, all piped and ducted below ground infrastructure will be located

outside the protected root area of retained trees. This includes the supply of mains

water, electricity, gas, fibre-optics and telecommunications.

4.2 All foul, storm and rainwater drains, soakaways and allied buried structures will be

located outside the RPA of retained trees. Details of any special precautions for the

installation of below ground pipes or structures will be provided in an AMS and shown

on a services plan.

4.3 Where this is not possible they will be installed in accordance with the National Joint

Utilities Council9 recommendations using a prescribed technique in order of preference:

a) Trenchless

The recommended depth of run should be below 600mm and launch and reception

pits located outside the RPA of retained trees.

b) Broken trench - hand dug

A combination of hand dug (c) and trenchless (a)

c) Continuous trench – hand dug

Within the RPA the soil will be removed using hand tools only. All roots greater than

25mm diameter will be retained and as many smaller roots as possible. Care will

be taken to avoid any damage to the retained roots and the trench will be covered

and backfilled as soon as possible.

5 Tree Protection

5.1 All trees to be retained will be protected by barriers to the recommendations of

BS5837:201210.

5.2 Protective Barriers

Protective barriers will be located as indicated on the attached tree protection plan

(AMS1) to ensure the proper protection of the retained trees’ root protection area

9 NJUG: Guidelines for the planning, installation and maintenance of utility apparatus in proximity to trees (Issue 2) 10 BS5837:2012: Clause 6.2 - Barriers and ground protection


Page: 7

(RPA). The protected area is designated the 'Construction exclusion zone' (CEZ)

and is indicated on the tree protection plan.

5.3 The barrier will comprise 2 metre high weld mesh panels supported by a secure vertical

and horizontal framework or where the level of risk does not necessitate the default

specification, the supplied concrete or rubber mounting trays. The panels will be

supported on the CEZ side of the barrier by stabiliser struts attached to base plates

secured with ground pins or a mounting block tray (Note 1 AMS1 & AMS2 – Tree

Protection Fencing).

5.4 Ground Protection

Where pedestrian or vehicular access within the RPA is necessary (trees 6 – 8 & 19),

the tree protection barrier will be set back and the ground between the protective

fencing and perimeter of the RPA will be protected in accordance with the Standard11

(AMS3 – Ground Protection).

5.5 Where scaffolding is within the RPA this will be installed above the appropriate ground

protection.

5.6 Where only pedestrian movements are anticipated, this will comprise a single thickness

of scaffold boards or similar material placed on top of a driven scaffold frame to provide

a suspended walkway, or on top of a 100mm depth compressible layer laid onto a

geotextile membrane.

5.7 For pedestrian operated plant and vehicles up to a gross weight of 2 tonnes, this will

comprise proprietary inter-linked ground protection boards placed on top of a 150mm

depth compressible layer, laid onto a geotextile membrane.

5.8 For construction traffic exceeding 2 tonnes, this will comprise a proprietary

system/precast concrete slabs laid on the existing soil surface. The construction will

be engineer designed to accommodate the anticipated loading and soil conditions.

11 BS5837:2012: Clause 6.2.3 – Ground protection during demolition and construction


Page: 8

5.9 Barrier Installation

The protective barriers will be erected and ground protection installed during site

preparation, before materials and machinery are moved onto the site and prior to site

clearance, demolition or construction. Any accidental damage to the barriers or ground

protection will be repaired immediately and the removal or relocation of any protective

barriers will only be permitted with the consent of the local planning authority. All tree

protection measures will be maintained until the completion of development unless

specified otherwise. Any changes to the specified tree protection measures will be

subject to the agreement of the local planning authority.

5.10 Construction Exclusion Zone

The parking of any vehicles or the storage of materials, chemicals, plant, machinery,

tools or the disposal of waste materials will not be permitted within the construction

exclusion zone (CEZ). The lighting of fires will not be permitted less than 10 metres

from the perimeter of the CEZ of any retained tree. Site huts and temporary buildings

will be located outside the RPA of retained trees unless otherwise agreed by the local

planning authority.

5.11 Alterations to existing levels, excavation or the removal of topsoil will not be permitted

within the RPA of retained trees.

6 Tree Maintenance

6.1 Where access facilitation pruning is required to provide safe access and adequate

clearance from the proposed building(s) this will be undertaken in accordance with the

recommendations of BS3998:201012. Initially this will comprise:

Trees 15 (Ash) & 16 (Goat willow)

Crown lift and reduce to provide 2 metres clearance between the proposed dwelling

and periphery of the crowns.

12 British Standard: Tree Work - Recommendations


Page: 9

The proposed pruning would reflect the character of the species, would not be

perceived from outside the site or be damaging to the character and appearance of the

conservation area. All proposed tree works will be detailed in a schedule of work and

submitted for the approval of the local planning authority.

7 Conclusions

7.1 The proposed development is in accordance with the recommendations of

BS5837:2012. The trees shown to be retained will be properly protected for the period

of development and their heath and safe life expectancy will not be adversely affected

by the proposed development.

7.2 The size of the dwelling has been reduced from the previous approved scheme which

is beneficial to the retained trees. All the trees included in the tree survey would be

retained and proposed tree works would not be detrimental to the character or

appearance of the conservation area.

Instructions

We are instructed to undertake a condition survey of trees on and immediately adjacent to the site. The purpose of the tree survey is to record information about trees that will inform site layout and design. This tree survey has been undertaken to the recommendations of British Standard 5837:2012 ‘Trees in Relation to Design, Demolition and Construction – Recommendations’. Unless otherwise instructed the survey includes all significant individual and groups of trees and woodlands likely to be affected by any proposed development or building operations. Shrubs, bushes and other vegetation have not been included. The tree survey data allows the application of the Standard1. The trees included in the survey have been assessed from ground level using the informal visual tree assessment method (VTA). This survey is not a tree safety inspection. Where structural defects, symptoms of decay or disease are noted a detailed tree inspection, which may require invasive testing, is recommended. Where access is restricted to off-site trees or by site conditions, vegetation or structures, a distant assessment is made and the measurements may be approximated.

2 BS5837:2012 - Table 1


Page: 4

Category A Green on plan Trees of high quality with an estimated remaining life expectancy of at least 40 years.

Subcategories

1 2 3 Trees that are particularly good examples of their species, especially if rare or unusual: or those that are essential components of groups or formal or semi-formal arboricultural features (e.g. the dominant and/or principal trees within an avenue)

Trees, groups or woodlands of particular visual importance as arboricultural and/or landscape features

Trees, groups or woodlands of significant conservation, historical, commemorative or other value (e.g. veteran trees or wood-pasture)

Trees in this category should be considered for retention as individuals or groups.

Category B Blue on plan

Trees of moderate quality with an estimated remaining life expectancy of at least 20 years.

Subcategories

1 2 3

Trees that might be included in category A, but are downgraded because of impaired condition (e.g. presence of significant though remediable defects, including unsympathetic past management and storm damage), such that they are unlikely to be suitable for retention beyond 40 years; or trees lacking the special quality necessary to merit the category A designation.

Trees present in numbers, usually growing as groups or woodlands, such that they attract a higher collective rating than they might as individuals; or trees occurring as collectives but situated so as to make little visual contribution to the wider locality.

Trees with material conservation or other cultural value

Trees in this category should be considered for retention as individuals or as groups but where possible preference should be given to the retention of category A trees.


Page: 5

Category C Grey on plan Trees of low quality with an estimated remaining life expectancy of at least 10 years, or young trees with a stem diameter below 150mm.

Subcategories

1 2 3 Unremarkable trees of very limited merit or such impaired condition that they do not qualify in the higher categories.

Trees present in groups or woodlands, but without this conferring on them significantly greater collective landscape value; and/or trees offering low or only temporary/transient landscape benefits.

Trees with no material conservation or other cultural value

Trees in this category will not normally be considered for retention as individuals but may be considered for retention as part of a group of, preferably, better quality (Category A or B) trees. They will usually not be retained where they would impose a significant constraint on development.

Category U Red on plan

Trees in such a condition that they cannot realistically be retained as living trees

in the context of the current land use for longer than 10 years.

Criteria

Trees that have a serious, irremediable, structural defect, such that their early loss is expected due to collapse, including those that will become unviable after removal of other category U trees (e.g. where, for whatever reason, the loss of companion shelter cannot be mitigated by pruning)

Trees that are dead or are showing signs of significant, immediate, and irreversible overall decline

Trees infected with pathogens of significance to the health and/or safety of other trees nearby, or very low quality trees suppressing adjacent trees of better quality.

Note: Category U trees can have existing or potential conservation value

which it might be desirable to preserve

Trees in this category will normally not be retained. However, they may be

considered for retention in the short term only where they are not a safety hazard and can be properly managed.


Page: 6

COMMENTS General observations on the physiological and structural condition of the tree. Where trees have been included in a Tree Preservation Order the TPO number may be indicated.

Tree Inspection Required

In some cases a more detailed inspection may be recommended to determine the tree’s safety and suitability for retention. This may involve invasive testing to properly investigate any suspected defect or the extent of any decay. Where a tree is scheduled under a TPO it is normal practice to notify the local planning authority before undertaking this type of investigation. Where trees are found to be unsafe to retain within the proposed use of the site, the tree may be down-graded to the unsuitable for retention category3. Trees requiring inspection are indicated on the plan by an outer red ring.

2 Tree Survey and Constraints Plan (TCP) The tree survey plan indicates the tree number, crown size and shape and has been colour-coded to indicate the condition of individual and/or groups of trees. Where trees are scheduled under a Tree Preservation Order (TPO) the TPO number may be shown on the plan. Additionally, the plan indicates the root protection area (RPA) as recommended in BS5837:2012. Where the plan is provided in electronic format (CAD) the following layers are used: TMC-Tree No Tree number in survey TMC-Code A Category A trees - Green TMC-Code B Category B trees - Blue TMC-Code C Category C trees - Grey TMC-Code U Category U trees - Red TMC-TPO Tree preservation order number TMC-RPA Root protection area – Magenta TMC-Inspection Outer trunk ring - Red

3 Root Protection Area (RPA) The root protection area (m2) for individual or groups of trees has been calculated as prescribed by the Standard4.

3 BS5837:2012 – Code U – red on plan 4 BS5837:2012 – Clause 4.6 Root protection area (RPA)


Page: 7

Using the stem diameter (STEM) as listed in the tree survey data5 the RPA area (m2) is calculated as 12 times the trunk diameter and shown on the tree constraints plan as a circle (magenta) centred on the base of the stem. For multi-stemmed trees a combined stem diameter is calculated as described in the Standard6. The size of the RPA is capped at 707m2 (i.e. stem diameter 125cm = 15m radius). The calculated RPA for high, moderate and low quality trees is shown in the tree constraints table. Where tree root growth may have been restricted by pre-existing site conditions, the shape of the RPA has been adjusted to reflect the most likely rooting pattern and distribution. In this case the overall size of the RPA (m2) has been maintained. The RPA for the high (Category A) and moderate (Category B) quality trees, which are the main tree constraints on a site, are plotted on the tree constraints plan (colour – magenta). This is the minimum area (m2) that should be left undisturbed around each retained tree. In some instances the RPA for low (Category C) quality trees may also be plotted (e.g. where there is a high proportion of trees in this category).

4 Using the Tree Survey and Constraints Plan (TCP) The Standard advises the tree survey should be used as a design tool in preparing the site layout plan. The tree survey data identifies the quality and value of the existing tree stock allowing informed decisions to be made concerning which trees should be removed or retained. Trees to be retained and removed:

The tree survey plan can be used as the base plan for all design work or overlaid onto the site layout plan. It is helpful if the TMC layers (TMC-) are retained unaltered within the drawing. If necessary layers should be turned off rather than deleted.

The high (Category A - green) and moderate (Category B - blue) quality trees are the best trees on the site and should be considered for retention. If this is not possible it is better to remove category B trees in order to retain category A trees.

Trees of low (Category C – grey) quality can be retained but they should not be retained where they would impose a significant constraint on development. It is preferable to remove low (Code C) quality trees in order to retain high and moderate quality trees (Categories A & B).

5 Tree survey schedule - page 8 6 BS5837:2005 - Clause 4.6.1 (a & b)


Page: 8

Trees unsuitable for retention (Category U - red) have a short safe life expectancy. However, where they form part of a large group or woodland their retention could be considered in some circumstances (e.g. where there would be minimal risk of injury or damage).

Levels:

The feeding roots of trees are generally concentrated in the uppermost 600mm of the soil. It is therefore important not to raise or lower soil levels within the RPA of any retained trees.

Minimum distance to buildings:

All proposed buildings and structures requiring foundations, where possible, should be located outside the RPA of any retained trees.

Where foundations are unavoidable within the RPA, it may be possible to use an alternative type of footing as recommended in the Standard7. Site specific and specialist advice regarding foundation design should be provided by a qualified arboriculturist and engineer.

Where possible buildings should be sited outside the crown spread radius of retained trees, leaving sufficient clearance for future growth and movement in windy conditions. Additional distance from buildings will be required in the case of young and middle-aged trees.

Hard surface areas:

Hard surface areas such as drives, parking spaces and footpaths or bin and cycle stores may be incorporated within the RPA provided they are of a no-dig construction and do not cover more than 20% of the existing un-surfaced ground.

Where hard surface areas are close to trees there should be a minimum clearance of 0.5m between the stem and any above ground buttress roots to allow for growth and movement.

Sufficient headroom should be provided above hard surface areas depending on the intended use of the area.

Veteran Trees:

Where trees are classified as veterans, the Standard8 advises there should be no new construction or hard surfaces within the RPA.

7 BS5837:2012 - Clause 7.5 Special engineering for foundations within the RPA 8 BS5837:2012 – Clause 7.4


Page: 9

Tree protection:

The RPA should also be applied in the siting of tree protection around all trees to be retained. The Standard9 advises this should be in the form of barriers and/or ground protection that should be maintained for the period of development. The tree protection barriers should be located at the edge of the RPA or the perimeter of the crown spread, whichever is the greater.

5 Tree Preservation Orders, Conservation Areas and Other

Restrictions

From 6 April 2012 all Tree Preservation Orders (TPO) and Conservation Areas with regard to trees, are regulated by the Town and Country Planning (Tree Preservation) (England) Regulations 2012. Tree Preservation Orders The new regulations cancel the provisions in every existing TPO, except for the information necessary to give the orders legal effect and identify the trees protected, and replace them with provisions in the new regulations. Before any trees are removed or tree works are undertaken it is strongly recommended that checks are made with the local planning authority (LPA) to ensure the trees are not scheduled under a TPO or sited in a conservation area. It is not the responsibility of Tree Management Consulting llp to undertake such checks. Conservation Areas Within a conservation area all trees of greater than 75mm in trunk diameter are protected by the regulations. The LPA must be notified, in writing, and given six weeks’ notice of any intended works. The LPA cannot refuse consent and if they have not replied within the six week period the proposed works may be undertaken within 2 years. If the LPA do not wish the works to be undertaken they must make a TPO. Planning Permission Where a full planning permission has been granted and the trees shown to be removed on the approved plan are scheduled under a TPO or are within a conservation area, normally they are exempt from the TPO and may be removed so far as it is necessary to implement the planning permission. Additionally, all notifications and works to trees must be in accordance with the conditions attached to the planning permission. This exemption does not apply to outline planning permissions. Felling Licence Where trees are not in a churchyard, private garden or public open space, a felling licence issued by the Forestry Commission may be required. Where full planning permission has been granted a felling licence may not be required.

9 BS5837:2012 – Clause 6.2 Barriers and ground protection


Page: 10

Wildlife Protection The Wildlife and Countryside Act (1981) and Countryside and Rights of Way Act (2000)

give statutory protection to wild birds, mammals, some invertebrate species and plants and it is important to ensure this legislation is complied with when carrying out any works to trees. A European Protected Species (EPS) mitigation licence may be required from Natural

England under the Habitats and Species Regulations (2010) if felling operations could

affect any EPS.
