1. INTRODUCTION

1.1 ASSIGNMENT

We have been instructed by Nick Davies Architectural designer to carry out a tree survey in

accordance with BS5837:2012 ‘Trees in relation to design, demolition and construction -

recommendations’ at an existing property formerly used as a social Club within the town of Pencoed in

Bridgend. In addition to the tree survey we have also been asked to design a suitable soft landscape

scheme as part of the overall proposal to develop the site for residential purposes.

1.2 REPORT METHODOLOGY

The methodology for preparing this report is in accordance with BS5837:2012 ‘Trees in relation to

design, demolition and construction - recommendations’ is as follows:-

Tree Survey Plan

The purpose of the Tree Survey is to identify significant trees on site that may be within influential

distance of any proposed development. The plan will record the condition of the trees, their quality

and benefits within the context of the development and their above and below ground constraints in

relation to both the site and any proposed development.

1.3 NEXT STAGE

This document is intended to be used as an aid for the site design and layout.

The report includes an Arboricultural Implications Assessment with Arboricultural Method Statements

and the successful implementation of this will require conformity to the guidelines and site monitoring.

1.4 LEGAL CONSTRAINTS

We are not aware of any legal constraints protecting these trees or but they are not within a

Conservation area and seem unlikely to be subject to a Tree Preservation Order, however it is

important to check with the Local Planning Authority on their status before any work commences.(See

3.4)

1.5 IMPLEMENTATION OF TREEWORK

All tree work should be carried out to BS 3998:2010 ‘Tree work - Recommendations’.

1.6 SOILS

No soil analysis has been undertaken at this site

2.0 The Site description and Development Proposal

2.1 Site description The site is close to the main centre of Pencoed and is occupied by a brick building which is currently

derelict and overgrown.

2.2 Development Proposal The proposal is to re develop the site to provide residential units in four blocks.

CONSTRUCTION Trees on site are of little value and the impact of the proposal is not significant.

SERVICES It is likely that excavations on site will be required to install services and impact on trees

is not significant

ACCESS The existing access to the site appears to be sufficient for traffic without the need for

entrance widening

APPENDIX 1

TREE SCHEDULE KEY The trees and groups of trees at the site have been assessed as per the recommendations set out in BS

5837 2012. Type Represents the type of vegetation being assessed. These are Tree (T), Group (G), Stump (S),

Woodland (W)

Tag No Each tree has been marked by a numbered tag for on site identification. Where possible this number

is related to, or similar to the given tree number. There may be occasions when the tag number bears

no relationship to the tree number, but is still useful for on site identification

Common Name

Botanical Name

The tree species have been identified and both common and botanical names are given.

Age Young – (Shown as Y in the schedule) juvenile tree with dominant leading shoot growth and short

side branches. Vigorous growth and often of conical form. Semi-mature – (Shown as SM in the schedule) young adult tree, leading shoot growth may not

always be dominant but side branches are usually ascending. Vigorous growth, flower and seed

production. Minimal deadwood. Early maturity – (Shown as EM in the schedule) adult tree with the main framework of the crown

formed. Not yet at full dimensions. Vigorous growth and some shedding of inner branches and

deadwood. Horizontal side branches. Mature – (Shown as M in the schedule) adult tree at full crown volume and dimensions. Maximum

flower and seed production. Dead wood likely within the crown and reiteration growth in the lower

canopy. Over mature – (Shown as OM in the schedule) loss of overall vigor and reduction of full dimensions

due to limb loss and branch tip die back. Major dead wood within the crown and possible hollowing

and cavities. Retrenchment of the crown through increased reiteration growth on the lower branches. Veteran / Ancient – (Shown as V in the schedule) a tree that has passed beyond maturity and is old

in comparison with other trees of the same species. They often have decayed or hollow stems and

branches and abundant deadwood. They are important for heritage, landscape and ecological value.

Height (m) Where site lines allow, tree height has been calculated by means of a laser clinometer and recorded in

metres. If the use of a laser clinometer is restricted due to confined space or obscuring vegetation, the

height of the tree may be estimated based on the surveyor’s experience. Adjacent trees or buildings with a clear view may be measured and used as a height scale. Where several trees are located in

close proximity, one tree may be measured and the other trees estimated using the measured tree as a

reference.

Diameter (mm) The stem diameter is measured in millimetres in accordance with Annex C of BS5837 2012.

Crown Height (m) Is the distance from the lowest point of the crown from ground level.

FSB Height (m) /Direction The height of the First Significant Branch (FSB) is recorded in metres and the direction of growth is

in relation to the cardinal points of the compass.

North (m)

South (m)

East (m)

West (m)

(Crown Spread)

As it is rare that a tree's crown is asymmetric, the crown spread is measured at the four cardinal points of the compass to give an estimated representation of the crown spread which is then recorded on the

tree survey plan.

Condition Physiological Condition

Each tree has undergone a brief preliminary visual inspection from ground level. This information is only relevant at the time of inspection because circumstances influencing a tree’s condition can

change rapidly. This section is divided into two separate sections:

G = Good – fully foliaged/twigged canopy for the tree’s situation with an indication of natural vigor

from shoot extension growth and signs of good vitality throughout the tree’s system.

F = Fair – signs of adequate vigour and vitality up to 70% canopy coverage. May show signs of slight stress such as branch tip die back, slightly sparse foliage, yellow or small foliage. Stress may

be alleviated by prescribed maintenance.

P = Poor – obvious signs of advance stress including less than 70% canopy coverage, crown die back, significant deadwood. Sparse and discoloured foliage.

D = Dead – moribund or dead trees

Comments Structural Condition

Any structural defects are noted such as splits, cracks, tight forks, rubbing branches, cavities, decay and the presence of pests or diseases. These may compromise the mechanical integrity of the tree’s

structure.

(Veteran trees may pose many physiological and structural faults yet still be considered in good condition for their age.)

Recommendations Following visual inspection preliminary recommended action, further detailed inspection, or

maintenance may be prescribed.

RPR (m)

Root Protection Radius

This is calculated from Annex D of BS 5837 2012 ‘Trees in relation to construction - Recommendations’.

RPA (m)

Root Protection Area

This measurement is the total area of root protection. This can be modified if necessary by the

Arboricultural Consultant.

Category The tree’s overall value is categorised in accordance to the cascade chart (table 1) of BS 5837 2005,

see Appendix 2 of this report.

In brief, the purpose of the tree categorisation is to identify and quantify the value of the existing tree

stock. This will allow informed decisions to be made concerning which trees should be removed or

retained should the development occur.

Category A

Trees of high quality and value that make a substantial contribution. Marked in light green on the tree

survey plan.

Category B Trees of moderate quality and value that make a significant contribution. Marked in mid blue on the

tree survey plan.

Category C Trees of low quality and value that provide only an adequate contribution. Marked in grey on the tree

survey plan.

Category U Trees in such a condition that any existing value would be lost within ten years. This includes trees

that should be removed for good arboricultural reasons. Marked in dark red on the tree survey plan.

There are no trees on site worthy of retention and the continuation of tree cover has been

considered within the soft landscape schedule that forms part of this report. In a previous report

dated June 2016 it was stated that hedgerow 3 may be retained . It is now advised to remove the

part of this hedgerow that falls within the site and to replace with a more suitable site screening

3.5 Soft landscaping and replacement Tree planting

Refer to Appendix

3.6 LEGAL CONSTRAINTS

Individual trees and woodlands in any location may be protected by legislation for various reasons.

The reasons for protection can include visual amenity, biodiversity, wildlife protection or to avoid

unnecessary tree loss. Substantial penalties can be incurred for contravention of legal protection. The

main type of protection in an urban setting is when trees are protected within a Conservation Area or

by a Tree Preservation Order (TPO) or if they are occupied by specific wildlife.

Conservation Area

In Conservation Areas, trees of a diameter greater than 75mm, measured at 1.5m from ground level are

automatically protected (except in certain circumstances) under the Town and Country Planning Act

1990. Notice of intent is required to be given to the Local Planning Authority (LPA) before work is

carried out. An application form can be downloaded from the LPA website. The LPA has six weeks to

decide whether the tree should be made subject to a Tree Preservation Order. If the LPA do not

respond within the six-week period, then the tree work that has been applied for may proceed.

Tree Preservation Order (TPO)

A Local Planning Authority (LPA) can protect trees and woodlands with a Tree Preservation Order in

the interest of good amenity. In general, it is prohibited in the Town & Country Planning (Tree

Preservation) (England) Regulations 2012 to cut down, top, lop, uproot, willfully damage or willfully

destroy a tree without the Planning Authority’s permission.

It will be necessary to apply to the LPA for permission to carry out any work on protected trees. The

LPA has eight weeks to respond to the application to either refuse or permit the work applied for. The

LPA can also make alternative work recommendations.

If an application for work is refused, or allowed subject to conditions, or if the council fails to deal

with the application within 8 weeks, the applicant has a right of appeal to the Secretary of State under

the provisions of section 78 of the Town and Country Planning Act 1990 (as amended).

At the time of inspection, we do not know of the specific protection applicable to this site. The work

specified in this report is necessary for reasonable management and should be acceptable to the LPA.

However, tree owners should appreciate that they may take an alternative point of view and have the

option to refuse consent.

Habitats Regulations

Bats, nesting birds and some mammals are protected under the Conservation of Habitats and Species

Regulations 2010, Wildlife and Countryside Act 1981 and (as amended) Wildlife and Countryside Act

2000. A risk assessment will be required prior to commencement of any tree work or felling to assess

the likelihood of disturbing or endangering any protected wildlife or habitat. If any protected species

are present in any of the trees, or if the tree has a known bird nest or bat roost, then consultation with

the Statutory Nature Conservation Organisation (SNCO) must be undertaken, prior to commencement

of work.

6. ARBORICULTURAL METHOD STATEMENTS

The function of the Arboricultural Method Statements and Tree Protection Plan is to provide the

construction contractors with a clear and concise instruction on how to carry out tree related work.

This includes the type and position of protective fencing and ground protection. General good practice

and excavation close to trees. The method statements have been attached to this report as appendices

so they can readily be reproduced as work sheets for the contractors.

7. FUTURE CONSIDERATIONS

If the proposed development goes ahead there are several factors that should be considered.

Implementation of works

We advise that any tree works be carried out by Qualified Arboricultural Contractors. The contractor

should carry out all tree works to BS 3998 Recommendations for Tree Work (2010) and as modified by

research that is more recent.

Trees subject to statutory controls

Most works to trees covered by a preservation order or within a conservation order require consent to

remove or prune. This can be obtained by writing to the local authority tree protection team. Note also

restriction on tree works under the Wildlife and conservation act 1981 in respect of mammals, birds

and bats as well as protected plant species.

• Maintenance – Retained trees within a garden situation will require regular maintenance for hazard

risk, size control and good husbandry reasons.

• A full soft and hard landscaping schedule, and a re-planting scheme along with soil resource plan and

soil analysis should be undertaken to accompany this report

1. INTRODUCTION 1.1 DEVELOPMENT SITE LANDSCAPING

This document is being prepared to support an application for a housing development on the site of the

former RAOB Social Club Heol Y Groes Pencoed Bridgend CF35 5PE

The aim of the planting scheme is to provide guidelines for the planting of shrubs around the grounds

of the site to enhance the visual amenity of the site.

1.2 ASSIGNMENT

We have been instructed by Nick Davies BA(Hons) to:

Prepare an outline landscape schedule for the site above in accordance with BS5837:2012 It should be

noted that the hard landscaping scheme, including detail on paving, and surfaces for parking is detailed

in plans from Nick Davies. This plan includes details on finished ground levels and has been used as a

basis for the soft landscaping plan provided with this report.

1.3 SCOPE OF WORKS

The scope of the soft landscape works will include:

The supply and planting of the specified shrubs;

A programme for maintenance of new plants;

A condition for replacement of plants that fail within the first five years of completion of the project.

The specification for plants included within this report is subject to the use of approved top and sub

soil soils for planting beds which will be filled with subsoil to BS 8601:2013 and topsoil to BS

3882:2015 to a depth of no less than 300mm for trees and shrubs being brought to site. Imported top

soil should supplied with certificate of compliance with BS3882 : 2015. A cross section and soil

profile has been included as part of this proposal.

2. THE SITE

2.1 SITE DESCRIPTION AND LOCAL CONTEXT

The site is in a residential area of Pencoed Bridgend with surrounding semi-detached and terraced

properties and a large car parking area.

2.2 SOIL EVALUATION AND IMPROVEMENTS REQUIRED

The site is mainly hard surfaced and overgrown and it is likely that due to the restricted areas of open

soil that planting beds and tree pits will have to be formed with imported certificated sub soil and top-

soil compliant with BS 3882 2015 and to BS 8601 2013. Plant beds will need to have a profile of

300mm of free draining top-soil over de-compacted sub soil. If soils on site are to be stripped there

will be a need for a soil resource plan, this must state whether the soils will be removed or stored on

site and how this will be achieved.

Imported Topsoil shall not contain weed seeds in quantities that cause noticeable weed

infestations in the final planting beds. Imported Topsoil shall meet the following physical and

chemical criteria:

1. Soil texture: loam, sandy clay loam or sandy loam with clay content between 15 and

25%. And a combined clay/silt content of no more than 55%.

2. pH value shall be between 5.5 and 7.0.

3. Percent organic matter (OM): 2.0-5.0%, by dry weight.

4. Soluble salt level: Less than 2 mmho/cm.

5. Soil chemistry suitable for growing the plants specified.

Imported Topsoil shall be a harvested soil from fields or development sites. The organic

content and particle size distribution shall be the result of natural soil formation.

Manufactured soils where Coarse Sand, Composted organic material or chemical additives

has been added to the soil to meet the requirements of this specification section shall not be

acceptable. Retained soil peds shall be the same color on the inside as is visible on the

outside.

Imported soil must be supplied with Product data and certificates: For each type of

manufactured product, submit data and certificates that the product meets the specification

requirements, signed by the product manufacturer, and complying with the following:

Submit manufacturers or supplier’s product data and literature certified analysis for standard

products and bulk materials, complying with testing requirements and referenced standards

and specific requested testing.

2.1 Planting beds for shrubs; The areas for planting on site are limited and grass will be used to

provide an amenity space with shrubs planted where appropriate to break up lines and provide

some interest and enhance the wider area. Shrub beds at the edge of paved areas should be at

least 0.75m wide and filled with suitable top-soil overlaying de-compacted sub soil to comply

with standards set out in the British standards as stated above. The top 100mm of soil should be

broken down into a fine tilth and levelled in preparation for planting and need to be subjected

to percolation tests as set out in BS 8545 B.2.4 and table B1.

2.2 Selection of plants:

Plants will need to be manageable for owners, suitable for location, sourced locally, and where

possible provide potential habitat or foraging opportunity for wildlife. If plants are stored, they will

need to be regularly watered to avoid drying out. The plants selected have been chosen for their

drought tolerance, a sheltered site, architectural interest and low maintenance.

PLANTING NURSERY STANDARD TREES, AND POST

MAINTENANCE

1.0 INTRODUCTION

1.1 This method statement describes the procedure required for the planting and post maintenance

of containerised trees and shrubs.

1.2 Although containerised trees can be planted throughout the year, we would recommend

planting in the dormant season between November and early March. Planting outside this

period would require careful watering management.

1.3 The recommendations for tree and shrub species and dimensions are detailed below and were

available at the time of this report but will be subject to availability:

2.0 METHODOLOGY

2.1 The Planting pits for trees will be no less than 0.75m.x 0.75 wide and dug to a depth of no less

than 450mm. The soil resource survey and soil resource plan will determine whether existing

soils or imported soils are used and planting pits will be filled with subsoil to BS 8601:2013

and topsoil to BS 3882:2015 to a depth of no less than 450mm for shrubs and 950mm for trees.

2.2 Mark out the size of the planting pit with a spade by scraping the edge along the ground

surface. The planting pit will be square in shape and be a minimum of 40cms larger than the

diameter of the containerised root ball. Screen planting areas should be marked out on site and

if required turf removed to create planting bed.

2.3 The final depth of the planting pits will be the same as the height of the root ball of the

tree/shrub from the base of the container to the inner compost level. This can be measured by

holding the spade or cane against the container and transferring the measurement to the

planting pit.

2.4 Loosen the base and sides of the planting pit with a garden fork and lightly firm the base of the

pit. The trees will be supported with a single 1.8m tanolisied tree stake driven into the base of

the planting pit at this point and tied to this stake with individual tree ties allowing good space

between the tree and stake. Hedging plants will not require support.

2.5 Prune any damaged branches and formative prune the crown as per to BS3998

“Recommendations for Tree Work” (2010). No heavy pruning or crown reduction will take

place at this time.

2.6 Transfer the trees/shrubs, removed from containers without disturbing the root ball, into the

planting pit; centrally position it with the stake(s) to ensure ties can be applied and check the

pit dimensions against the root ball.

2.7 Ensure that the root ball is not disturbed but that roots are teased out to aid their spread and that

the final soil levels do not cover the root collar.

2.8 Any weed growth will be removed from the surface of the root ball and disposed of.

2.9 The approved backfill soil mix as determined by the SRP will be placed into the planting pit,

filling the void between the root ball and the sides of the planting pit. The approved top soil

will be used for topping up, if required. The backfill shall be worked around the root ball in

layers of 10 – 15 cms with each layer being carefully firmed using the sole of the foot without

damaging the root ball.

2.10 During the process of backfill, the trees/shrubs will continually be checked for straightness.

2.11 Any leftover soil and debris arising from the planting will be removed and disposed of

accordingly.

2.12 The trees and shrubs will be mulched with a well composted organic mulch such as woodchip

to a depth of 8cms when settled. The mulch will be placed around the base of the tree to a

diameter of no less than 1m to form a bund for water retention. No build- up of mulch will be

situated around the base of the stem as any heat produced by the mulch may kill the cambium

and also prevent respiration.

2.13 The trees/shrubs will be watered immediately by slowly filling the mulch bund with ten litres

of water allowing for the water to soak into the root ball and planting pit.

1. MAINTENANCE

3.1 During the first two growing seasons after planting, the trees/shrubs will be watered regularly

especially during dry periods from March to October. The amount of water required will be

dependent on the soil type but water logging will be avoided. Any water should be applied

slowly avoiding run off away from the root ball. An ideal way to achieve this is with a seep

hose placed in a spiral pattern around the base of the tree. Tree stakes can be removed at this

point or if the root system has not sufficiently established the tree should be assessed for

replacement or re staking.

3.2 All grass and weed compaction around the base of the tree to a minimum of 1m diameter shall

be eliminated in the first three growing seasons.

3.3 The mulch shall be topped up to maintain a depth of 8cm during the first three growing

seasons.

3.4 The ties and stake can be removed once the root system has established in the ground and the

tree is firmly rooted within the first two years. Shrubs will require clipping annually once

established at required height.

3.5 Any trees or shrubs dying within the first 5 years of completion will be removed and replaced

with similar size and species.

4.0 MATERIALS

4.1 Subject to the outcome of the Soil Resource Survey and Soil Resource Plan

Imported Subsoil: Handled stored and of quality to comply with specifications in guideline BS8601 ;

2013

Imported top soil should supplied with certificate of compliance with BS3882 : 2015 (if required )

Contact: Crown Hill Top soil supplies

Imported Topsoil shall meet the following physical and chemical criteria:







Supports should comprise x3 untreated wooden stakes set as an arrowhead avoiding roots, no more

than one-third tree height and with hessian nature ties, or the timber staple as per the attached. Mulch

should be hardwood bark chip, to Landscape Institute specifications, of 50mm depth tapered to 25mm

over the root-ball and applied over a cleared area equating to 2m². Stakes and ties should be removed

after no more than 2 growing seasons.

TREE PIT SECTION

Please note the final tree pit profile and soil specification design will be determined by the findings of the soil resource survey and sub soil conforming to BS 8601:2013 and topsoil to BS 3882:2015 will be used as a planting medium

PLANTING CONTAINERISED TREES, SHRUBS, AND POST

MAINTENANCE

1.0 INTRODUCTION

1.4 This method statement describes the procedure required for the planting and post maintenance

of containerised shrubs. It is the responsibility of the developer or developers agent to

ensure a maintenance program is implemented

1.5 Although containerised plants can be planted throughout the year, we would recommend

planting in the dormant season between November and early March. Planting outside this

period would require careful watering management.

1.6 The recommendations for shrub species and dimensions are detailed below and were available

at the time of this report but will be subject to availability:

2.14 METHODOLOGY

2.15 The Planting beds for shrubs will be no less than 0.75m. wide and dug to a depth of no less

than 450mm. The soil resource survey and soil resource plan will determine whether existing

soils or imported soils are used, and planting beds will be filled with subsoil to BS 8601:2013

and topsoil to BS 3882:2015 to a depth of no less than 450mm.

2.16 Planting beds will need to be formed with edging stones set in concrete or treated timber rails

supported on short stakes at 1.0m intervals driven into the ground.

2.17 The plants should be spaced out evenly across the prepared beds and pits made for the plants. If

dry the pits should be filled with water and the plants plunge planted ensuring they are planted

to the correct depth with soil levels at the root collar. Soil should then be firmed around each

root ball to avoid frost lift.

2.18 Prune any damaged branches.

2.19 Any weed growth will be removed from the surface of the root ball and disposed of.

2.20 The approved backfill soil mix as determined by the SRP will be placed into the planting pit,

filling the void between the root ball and the sides of the planting pit. The approved top soil

will be used for topping up, if required. The backfill shall be worked around the root ball in

layers of 10 – 15 cms with each layer being carefully firmed using the sole of the foot without

damaging the root ball.

2.21 During the process of backfill, the trees/shrubs will continually be checked for straightness.

2.22 Any leftover soil and debris arising from the planting will be removed and disposed of

accordingly.

2.23 The shrubs will be mulched with a well composted organic mulch such as hardwood bark chip,

to Landscape Institute specifications, of 50mm depth tapered to 25mm over the root-ball and

applied over a cleared area equating to 2m² The mulch will be placed across the length and

breadth of the shrub beds to control weed growth and for water retention. No build- up of

mulch will be situated around the base of the stems as any heat produced by the mulch may kill

the cambium and also prevent respiration.

2.24 The shrubs will be watered immediately by slowly filling the mulch bund with ten litres of

water allowing for the water to soak into the root ball and planting pit.

3. MAINTENANCE

3.5 During the first two growing seasons after planting, the/shrubs will be watered regularly

especially during dry periods from March to October. The amount of water required will be

dependent on the soil type, but water logging will be avoided. Any water should be applied

slowly avoiding run off away from the root ball. All grass and weed competition shall be

eliminated in the first three growing seasons.

3.6 The mulch shall be topped up to maintain a depth of 8cm during the first three growing

seasons.

3.7 Shrubs will require clipping annually after flowering in the dormant months and grasses will

require old growth removed early in the new year. Hedgerow plants will require clipping once

established at required height.

3.5 Any trees or shrubs dying within the first 5 years of completion will be removed and replaced

with similar size and species.
