Report Structure
This document combines the three elements which provide comprehensive information to
BS5837:2012 on:
• the quality and value of the trees on a development site.
• an assessment of how they may be affected, and
• how they will be protected during the development works.
The report is generally in accordance with British Standard BS 5837: 2012 Trees in relation to
Construction: Recommendations.
Part A of this document is the Arboricultural Survey.
The Arboricultural Survey provides the basic working data on the trees. The preamble
(section A4 page 9) describes how the trees are measured, assessed and valued, and the
survey data is at Appendix 2 at the end of the document. This appendix includes data relating
to the Root Protection Areas around each tree.
Part B is the Arboricultural Impact Assessment
The Impact Assessment outlines the likely impact which the proposed development may have
on the trees.
Part C is the Arboricultural Method Statement
The Method Statement proposes a methodology for tree protection during the development
works, and the Tree Protection Plan indicates the locations of the various protection
measures.

Part A: Arboricultural Survey
Executive summary
A single tree is present on/adjacent to the site on the corner of the junction of Leckhampton
Road and Langdon Road, that being a high-value Lime tree growing in the highway verge at
the front of the property. A number of other mature street trees are present nearby; a
second Lime tree stands just to the south of Langdon Road, and other trees including a large
London Plane tree stand on the opposite side of Leckhampton Road.
The rooting area of the tree as given in the British Standard (BS5837:2012) intersects with the
front elevation of the existing building. The ground conditions are such that the likely rooting
area of the tree is uncertain but it is assumed that rooting has taken place beneath both the
highway pavement and the building.
It is proposed that the existing building will be demolished and that a new building will be
constructed on an enlarged footprint. A methodology for these works is given in Section C of
this report which aims to protect the tree’s roots and to create conditions beneath the new
building which will optimise the ability of the tree to continue to exploit these areas of
ground.
This report supersedes a previous arboricultural report (37.69) in support of an earlier
planning application for the same property.
A1. Introduction
A1.1 Instructions were received from Evans Jones Planning, on behalf of their clients M.r &
Mrs. P. Artus, to report on the condition and quality of a tree adjacent to 252 Bath
Road, Cheltenham. Demolition of the existing building and re-construction on an
enlarged footprint is proposed, together with provision for vehicular parking to the
rear. Information on the nearby trees is required, to BS5837:2012,1 to inform the
design and the planning process.
A1.2 I visited the site to survey the trees on 15th
October 2018. I am an independent
Arboricultural Consultant with than 37 years experience in the industry, I hold the
Professional Diploma of Arboriculture and I am a Fellow of the Arboricultural
Association.
A1.3 The accompanying Tree Constraints Plan (38.39.01) is based upon a topographical
survey by Cotswold Surveys: 252 BATH RD /01, Existing Site Survey.

A2. Site Description & Discussion
A2.1 The site is on the corner of Bath Road and Langdon Road. On the highway pavement
approximately 5m from the front elevation of the existing buildings is a high-value
mature Lime tree. The tree appears to be in good condition and it is in a prominent
location on the road junction.
A2.2 There is no soft ground around the tree into which it can root and its roots must
therefore have developed beneath the various hard surfaces which surround it. Tree
roots spread widely and have been shown to extend up to 1.5 x the height of the tree.
The potential rooting area of this tree therefore includes the concrete paving slabs of
the pavement, possibly the carriageway if its roots have not been over-disturbed by
trenching, and beneath the existing buildings.
A2.3 The land is level and the 1:50,000 British Geological Survey map of the area indicates
that the subsoils are probably derived from the Lower Lias Clay (Charmouth
Mudstone), with deposits of Cheltenham Sand being nearby to the north. I
investigated the quality of the subsoil by augering through the adjacent, vacant tree
pit on the highway pavement (Langdon Road). To a depth of around 600mm the soil
appeared to have been disturbed in recent times and contained brick fragments etc.
The principal soil constituents however appeared to be silt and sand.2 The underlying
clay became predominant within the sample at around 800mm below the level of the
pavement.
A2.4 In those areas of Cheltenham where the Cheltenham Sand is present,3 highway trees
grow noticeably better, and live longer than where they have been planted in areas
where the clay is not overlain by the sand. This is principally because almost all tree
species require soils to be well drained and aerated.4
A2.5 The good growth of this tree strongly suggests that the soil conditions are
satisfactory.5 The evidence from the borehole indicates that relatively free-draining
soil conditions exist on the site; if they did not, it is unlikely that this tree would remain
in good condition in the absence of any soft ground around it.
A2.6 The plan6 extract below indicates that services are present within the pavement
between the tree and the building. The implications for the tree are uncertain.
2 The Cheltenham Sand is thought to have been wind-blown (Aeolian deposits); the clay is known to have been
was deposited in marine conditions. It is possible that the silty sands, which occur widely across the town,
formed in intermediate conditions around the edges of the accumulated sand. 3 These include, for instance, Pittville Circus Road, Leckhampton Road, Arle Road & Alstone Road.
4 Species vary in their tolerance of drainage conditions. Limes are moderately tolerant of compromised rooting
conditions. London Plane trees are especially adaptable and able to thrive in urban conditions. 5 Not so compacted or anaerobic that roots cannot grow freely.

A3. Arboricultural Constraints
A3.1 Where trees are to be retained, the principal constraint upon the site is the need to
avoid disturbance of their principal rooting areas (the Root Protection Areas) and/or
compaction of the soil. Soil compaction is a frequent, and indirect, cause of root
damage.
A3.2 There could be some ground movements related to shrinkage and re-expansion of the
subsoil (generally referred to as subsidence and heave, respectively) if a sufficient clay
fraction is present in the soil. Precautions may be needed in respect of the
foundations of the new building to avoid damage as a result of the continuing growth
of any retained trees (subsidence), or re-expansion of the soil following their removal
(heave). In the case of heave, although there is no proposal to fell the tree at this
time, precautions may be required to make provision for its removal or death at some
time in the future.
A3.3 The shade cast by trees may attenuate the light levels to the main living rooms of
proposed buildings. An indication of the shade pattern on the tree shown at its
present height is given on the Tree Constraints Plan.

A4. Tree Survey
The survey was carried out by Graham King MRAC, Dip.Arb.(RFS), F.Arbor.A. Only
those trees which are considered relevant to the purposes of the survey have been
included, and no consideration was given to any development proposals in the
collection of the data. The following data were collected and categories assigned:
A4.1 Tree Number
The trees are identified by their Tree Numbers given in the appended schedule
(Appendix 2), and on the accompanying Tree Constraints Plan.
A4.2 Species
SPECIES is recorded giving the vernacular and scientific names.
A4.3 Tree Height
TREE HEIGHT was estimated with a clinometer.
A4.4 Stem Diameter
STEM DIAMETER is measured at 1.5m high and is rounded down, in centimetres.
A4.5 Branch spread
The BRANCH SPREAD was estimated on the four compass points and is given in
metres.
A4.6 Lowest branches or Crown Height
The lowest branches or the CROWN HEIGHT, is assessed approximately, in metres.
Where the lowest significant branch occurs on one side of the tree only, this is noted
in the schedule in the column “Side”. Where the orientation is specified as “All”, the
lowest branches are evenly arranged around the tree.
A4.7 Age code
i. Newly-planted (NP) Planted within the last 5 years
ii. Young (Y) Well established trees which might be moved or easily replaced.
iii. Semi-mature (SM) Well established trees now growing strongly but not yet
mature.
iii. Early-mature (EM) Mature trees less than one third life expectancy
iv. Mature (M) Trees between one third to two-thirds life expectancy.
v. Over-mature (OM) Trees of greater than two-thirds of anticipated life
vi. Dead, dying or dangerous: (D)
A4.8 Physiological condition may be difficult to assess if trees are out of leaf in winter or
in early leaf in the spring. The condition of the foliage in mid to late summer can be
a good indicator of a tree’s physiological condition, which is recorded as good, fair,
poor or dead.
A4.9 Structural condition is recorded as good, fair or poor.

A4.10 LIFE EXPECTANCY is recorded in years and is an approximate judgement of the likely
useful life of the trees. The Standard suggests that 'A' class trees should have a
minimum of 40 years safe useful life expectancy, 'B' class trees a minimum of 20
years safe useful life expectancy, and 'C' class trees a minimum of 10 years life.
A4.11 Tree Quality Assessment: The BS 5837:2012 tree quality assessment chart is
included at Appendix 1 below and should be considered together with the
following. The provisions of the chart may be summarised as:
Class A: Exceptionally good trees or arboricultural features with >40 years
useful safe life.
Class B: Good trees with a minimum of 20 years useful safe life.
Class C: Unremarkable trees of limited merit. Minimum safe life of 10 years.
Class U: Unsuitable for retention. Likely to have <10 years useful safe life.
A4.11.2 In addition to the provisions of the appended Chart Intermediate classes not
given in the British Standard are used in this report as follows:
A/B: A good, or very good, tree. A-class trees are recognised as having
particular and possibly indefinable qualities which make them special. These
trees may or may not posses those qualities.
B/C: A good tree which is tending towards the average, or a good tree which
might nonetheless be replaced within a reasonable number of years by new
planting. These trees would normally not constrain the use of the site.
C/U: a tree which probably will attain 10 years useful safe life but one which
is of such low value that it is barely worth retention, or the retention of
which might have a negative landscape value.
A4.11.3 The classification of the value of trees by the tree surveyor is unavoidably subjective
and it is possible that the Local Planning Authority may not always agree with the
values given in this report. Pre-application advice is generally advisable. In
particular, the value of Ash trees may be debated because Ash Dieback Disease is
new to the UK and there is no consensus on the effect it may have on the population
Ash trees.
A4.12 Preliminary management requirements
General guidance is given regarding tree surgery that may be required and the
condition of the trees was assessed only to establish their status within the planning
system. The safety and condition of trees were not assessed in detail.
A4.13 Root Protection Area
A4.1.13 The Root Protection Areas are an estimation of the minimum area which a
tree will require for continuing growth and is not a representation of the
total extent of their roots.

A4.13.2 The Root Protection Areas of trees classified A-C (Appendix 1) are given in
the appended schedule (Appendix 2). The RPAs are shown as regular circles
around the trees on the arboricultural plans.
A5. The Tree Constraints Plan
A5.1 The British Standard BS 5837:2012 recommends that a plan showing the
constraints upon development which the trees pose, are considered at the
design stage. For this purpose the Tree Constraints Plan should show:
• the position of the tree.
• the shape of the crown of the tree, accurately represented and colour
coded to show the category of the trees in accordance with the Tree
Quality Assessment chart.
• the recommended Root Protection Area, drawn initially as a circle,
although subsequent variation of the shape of the area may be
appropriate.
• a representation of the shade which the tree casts.
A5.2 Tree Quality Assessment
Details on Tree Quality Assessment can be found in the extract from BS5837:
2012 at Appendix 1.
A5.3 Root Protection Areas
Details of the Root Protection Area are given at section 4.13 above. The radii
and area of the Root Protection Areas drawn as a regular circle around the
tree is given in the schedule of data at Appendix 2.
A5.4 Shadow patterns
The shadow of the principal tree only (T1), are shown at its present height.

A6. General Considerations
A6.1 Trees and shrubs are living organisms whose health and condition can change rapidly.
The health condition and safety of trees should be checked regularly by a suitably
qualified person, preferably at least once a year, and the conclusions and
recommendations herein are valid for two years. This report is valid for 5 years.
A6.2 Tree work should be carried out by skilled specialist contractors who should be
covered by at least £5 million of public liability insurance. Work should be carried out
in accordance with BS 3998 (2010): Recommendations for Tree Work. When carrying
out works, the Wildlife & Countryside Act 1981, the Countryside & Rights of Way Act
2000 (as amended) and all other legislation covering the protection of wildlife must be
observed. It is unlikely that the tree would offer suitable habitat for bats to roost at
any time of the year.
A6.3 The tree is within the Cheltenham Central Conservation Area and it is presumed to be
the responsibility of the Highways Authority. Any works to the tree will require six
weeks’ notice to be given to Cheltenham Borough Council as well as the permission of
the tree owner (presumed to be Gloucestershire County Council).

Arboricultural Impact Assessment and tree protection methodology
The accompanying Tree Protection Plan (38.39.02A) is based upon Coombes Everitt drawing
number 841:81-112E.
B1. It is proposed that the existing buildings be demolished and that a new building be
constructed on an enlarged footprint. The Root Protection Area of the tree, drawn as
a regular circle around it, intersects with the line of the front of the existing buildings.
The Root Protection Area will intersect with the paved entrance to the new building,
outside the line of the foundations.
B2. Ground conditions (section A2 above) are such that it is likely that the tree has
developed roots widely across the site and beneath the building, as well as within the
highway pavement and possibly beneath the carriageway. It may be that rooting
conditions beneath the pavement and the existing buildings are better than under the
carriageway, although it is known that there are services under the pavement between
it and the building.
B3. It is therefore proposed that piled foundations will be used to enable the tree to
continue to exploit the area beneath the building, both within and beyond the extent
of the Root Protection Area as shown as a regular circle around it.
B4. There will be no excavation of the existing soils beneath the building other than to
construct the piles upon which the building will be supported. The bases of the
associated ground beams will be set no lower than existing ground level. A
methodology for the demolition and construction works is given in Section C of this
report. This aims to protect the tree’s roots and to create optimal conditions beneath
the new building which will enable the roots to continue to exploit these areas.
B5. Trenching for services
Where trenching for services is required beneath the building and/or within the root
protection area of the tree, this will be by hand and as in section B6. below.
B6. The seating area:
• Any excavation of the seating area will be by hand and all roots of diameter >25mm
will be preserved with the bark intact on all sides.
• Exposed roots will be covered by a waterproof membrane/sheet to prevent
desiccation and/or damage by frost.
• The roots will be sleeved with a minimum of 25mm of sacking in multiple layers
wrapped around the roots before back-filling with aggregate.
• The surface of the seating area will be of a porous material (to be agreed) to allow
water infiltration to the tree’s roots.

B7. Tree protection
The stem of the tree up to the base of the lowest branches will be protected by a box
of plywood or weldmesh panels. It will be erected without the use of stakes driven
into the ground and will be completed prior to the commencement of all demolition or
construction works.
B8. Consideration will be given to using non-slip surfaces for outside areas within the site
that are beneath the crown of the tree, where people walk. This is to address the
frequently encountered phenomenon of slippery honeydew being produced by the
tree in periods of hot weather.

Part C: Arboricultural Method Statement
The Arboricultural Method Statement will be issued to the contractor as part of the contarct
documents, and a copy will be available at all times on the site.
Part C. Section 1: Tree surgery
C1.1 Minor crown lifting (removal of low branches) will be undertaken only to clear
scaffolding. Any other branch removal would require the permission of Cheltenham
Borough Council.
Part C. Section 2: Tree Protection methodology
C2.1 Tree protection
The stem of the tree as high as the first branches will be protected by a plywood box
built around it and cross-braced such that it is not attached to, or touching, the stem
of the tree at any point. A compressible layer of polystyrene will be included between
the plywood and the tree. The installation of these measures will be subject to the
written approval of Cheltenham Borough Council prior to commencement.
C2.2 Ground protection
C2.2.1 It will be necessary to protect all areas of the ground against compaction within the
site during construction, as well as any areas of the highway pavement where the
existing paving is lifted at any point during the works. Where they have been retained,
the existing hard surfaces will provide sufficient ground protection during demolition.
C2.2.2 Ground boards will be minimum 19mm thickness shuttering plywood for pedestrian-
only access. Any vehicles which need to operate within the site will be tracked and
work only over ground which is protected by temporary roadway sections of a type
agreed with the Local Planning Authority.
C2.3 Demolition
C2.3.1 All demolition works will be undertaken with arboricultural surpervision which will be
on a daily basis.
C2.3.2 Following removal of the existing buildings, the remaining hard surfaces (floors,
outside paving etc.) will be removed by machines working only from remaining hard
surfaces or temporary roadway sections. The material will be removed by pulling it
outwards towards the highway (Leckhampton Road or Langdon Road).
C2.3.3 There will be no excavation of the soil below the existing hard surfaces and it may be
necessary to amend the piling layout to take account of obstructions within the soil
such as the foundations of the former building etc. which will remain in situ if below
ground level.

252 Bath Road, Cheltenham
October 2018
18
C2.4 Foundations and piling
C2.4.1 Following finalisation of the piling layout, ground irregularities which would prevent
the use of a tracked piling rig will be made-up using 20mm-40mm gravel and blinded
(if required) with sharp sand.
C2.4.2 The piling rig and any other machinery will work only off temporary roadway sections,
or other equivalent load-bearing surface, in order to prevent soil compaction. The
work will be undertaken only with arboricultural supervision which will be on a daily
basis.
C2.4.3 The bases of any ground beams will be set no lower than ground level and provision
may be required for a void former to be installed below the beams. The beams will be
craned into position, or cast in situ by operatives working from ground boards, or the
temporary roadway sections, which protect the soil against compaction.
C2.5 Trenching for services
C2.5.1 No trenching for the installation of underground services will take place within the
Root Protection Area of the tree (7.6m from the centre of the main stem at ground
level).
C2.5.2 All trenching requirements for services will be subject to the prior approval of
Cheltenham Borough Council and will be undertaken by hand under arboricultural
supervision. All roots of diameter >25mm will be preserved. Exposed roots will be
covered by a waterproof membrane/sheet to prevent desiccation and/or damage by
frost. The roots will be sleeved with a minimum of 25mm of sacking in multiple layers
wrapped around the roots before back-filling with aggregate. The surface of the
seating area will be of a porous material (to be agreed) to allow water infiltration to
the tree’s roots.
C2.5.3 Rainwater will be led to soakaways beneath the building. The soakaways will be
axcavated by hand and no roots of diameter >25mm will be severed in the
construction of the soakaways. If necessary, the location of the soakaways will be
varied to avoid tree rots of diameter >25mm.

C2.6 The seating area
• All excavation of the seating area will be by hand and all roots of diameter >25mm will
be preserved with the bark intact on all sides.
• Exposed roots will be covered by a waterproof membrane/sheet to prevent
desiccation and/or damage by frost.
• The roots will be sleeved with a minimum of 25mm of sacking in multiple layers
wrapped around the roots before back-filling with aggregate.
• The surface of the seating area will be of a porous material (to be agreed) to allow
water infiltration to the tree’s roots.
C2.7 Disposal of fluids
During demolition and construction all fluids which are potentially harmful to plant
roots including, but not restricted to, concrete/cement washings etc., will be
discharged only into a skip. They will not be disposed of onto the ground under or
around the proposed building.

Part C. Section 3: Arboricultural supervision
C3.1 The protective box around the stem of the tree will be installed and be subject to
inspection and approval by the Local Planning Authority at a pre-commencement
meeting between the Cheltenham Borough Council tree officers, the main
contractor/project manager and the project arboriculturist. No demolition or
construction works, including the delivery of materials or machinery, will commence
until written agreement has been received from the Local Planning Authority that the
protective measures have been are satisfactorily installed. It will remain in position
until the written permission of the Local Planning Authority has been obtained for
their removal at the end of the project.
C3.2 Demolition, and all works to install the foundations and the soakaways will be
subject to daily arboricultural supervision. All works will be subject to
arboricultural supervision by the project arboriculturist. Records will be maintained
of progress and advice given to the project manager and these will be submitted to
the Local Planning Authority monthly.
C3.3 Following demolition, and where tree roots are exposed or might become desiccated
where close to the ground surface, they will be protected from sunlight and drying by
being covered with layers of hessian. The hessian will be dampened when necessary
to prevent desiccation.
Part C. Section 4: Tree planting
C5.1 In the first planting season following construction, one tree (Pyrus ‘Chanticleer’) or
other to be agreed with the Local Planning Authority, will be planted at the location
within the pavement of Langdon Road as indicated on the Tree Protection Plan.
Additional trees will be planted within the site including Snowy Mespilus
(Amelanchier Canadensis) and Crataegus oxyacantha ‘Paul’s Scarlet’, as indicated.
The trees will be container-grown advanced nursery stock (minimum 10-12cm girth
at 1m high).
C5.2 A diagram giving detail of the planting pit is appended to this report. Planting to be to
BS 8545:2014. Planting will be to be to BS 8545:2014. The trees to be supplied in
accordance with the National Plant Specification from a HTA approved nursery. They
will be planted to a depth appropriate to the size of the containers, and the backfill
will consist of soil of a reasonable quality. No fertiliser will be added to the backfill,
which will be firmed but not compacted.
C5.3 The trees will be double-staked and secured to crossbars with rubber spacers at no
greater than one third of the trees’ height. The stakes to be straight, peeled, treated
softwood, free from knots and installed to avoid damage to the rootball.

Flowering Pear
(B1)
Newly planted
small tree
Building to be constructed on piled foundations.
Ground beams will be set no lower than existing
ground level and foundations will be designed to
allow for the continuing growth of the tree's roots
beneath the building.
The existing building to be demolished
using only tracked machinery working
from protected ground in order to
minimise soil compaction.
Tree to be
removed

Tree to be planted
if underground
services allow
Likely (approximate)
area into which the Lime
tree T1 has rooted
preferentially, where
rooting conditions are
more favourable
All excavation within this
area will be by hand and
all roots of diameter
>25mm will be preserved
with the bark intact on all
sides. The roots will be
covered with a waterproof
membrane at all times to
protect against frost
damage. Roots will be
sleeved with min. 255mm
of wrapped sacking to
prevent abrasion when
aggregate is back-filled.
Surfacing of the seating
area to be of a porous
material to allow water
infiltration to the tree's
roots
