1. INTRODUCTION

1.1 Instruction: This advice has been prepared for Martin Arnold(hereafter; client) and

is in respect of the tree related planning considerations at the Land adjacent to

Flaxyard Sumner Road, London, SE15 5QS (hereafter; site).

As the proposal relates to development works at site, the advice herein is produced

in accordance with the British Standard 5837 : 2012 ‘Trees in Relation to Design,

Demolition and Construction - Recommendations’ (hereafter; BS5837).

1.2 BS5837: The scope of BS5837 is to provide guidance on how trees and other

vegetation can be integrated into construction and development design schemes.

The overall aim is to ensure the protection of amenity by trees which are

appropriate for retention.

1.3 Scope of this advice: This advice has been produced in accordance with BS5837 and

is intended to demonstrate the site’s realistic arboricultural constraints and assist

with the design process. The objective is to systematically assess and provide

suitable recommendations regarding the proposal’s potential impact on trees and

vice versa.

1.4 Following instruction the consultant surveyed the site on the 06th Sept 2019 where a

site walkover and BS5837 tree survey were carried out; all trees on site and around

the application boundary were surveyed from ground level and plotted as either an

individual or a tree group.

1.5 This advice is subject to caveat at Appendix I, outlines relevant terms and

definitions at Appendix II and constitutes the findings of the preliminary site

assessment and associated arboricultural recommendations.

1.6 The survey data and site observations use the supplied topographical survey to

illustrate the surveyed trees in plan format as a ‘Tree Constraints Plan’ (hereafter;

TCP); the TCP and the tree survey data table are at Appendix III.

2. SITE INFORMATION & TREE ASSESSMENT

2.1 The site is currently an area of open land currently open to the public which is

bordered by Sumner House a Primary school to the north and west also a leisure

centre to the east and the backs of a row of shops facing onto Peckham Road to the

south. The main section is dived up into roughly triangular shaped sections by

existing paths and roadways. There is an addition to the site facing onto Peckham

Road and to the south of the Peckham Pulse Leisure Centre

2.2 Proposal: I understand from the proposals available that it is intended to construct 3

new blocks within the site. 2 detached separate blocks and a further block that will

be an addition to the row of shops along Peckham Road. This has now been

confirmed and is included in the current plans provided by the client namely 3631-

LB-FY-00-DR-L-9000 and also landscape level plans 3631-LB-FY-00-DR-L-9014 and

3631-LB-FY-00-DR-L-9015

2.3 The site requires consideration from an arboricultural perspective due to the presence

of trees on and around the site; these trees are deemed to be within impacting

distance of the existing property and potential construction area.

2.4 The trees -

2.4.1 The tree survey and assessment resulted in the BS5837 quality/retention categories of

‘B’-Moderate, ‘C - low’ and ‘U – Unclassified’ being attributed to trees/tree groups; it

is also worth noting that the BS5837 circular RPAs are considered to halt at the extents

of existing property.

2.4.2 There are a few established features on site the most significant of these trees are

classified as ‘B’ class. These are concentrated particularly around Sumner House T1

to T10 and T11, T13, T14 and T15. The remaining trees are ‘C’ or ‘U’ class.

2.4.3 There are identified defects to the surveyed trees G3 and T20, this has resulted in the

recommendation for tree removal, i.e. the category ‘U’ trees.

2.4.4 No council search/contact has been requested and hence confirmation as to whether

any of the trees are protected by Tree Preservation Order was unavailable at the time

of writing this advice - please advise if this detail is at your disposal and/or confirm

whether a conservation area and TPO check is to be made on your behalf as part of

this advice.

3. FINDINGS & RECOMMENDATIONS

3.1 The following information, as with the prior contents of this report, should be read

with the appended tree data table and tree constraints plan (19450/TCP/01/).

3.2 General Considerations for Tree Retention / Removal

3.2.1 Based on the boundary line location/neighbour’s site location of T1-T10, T14, T15

their retention and protection is to be assumed as part of the scheme.

3.2.2 The remaining trees are categorised as either ‘B’ or ‘C’, The ‘C’ category trees some

trees are of limited scale or remaining life expectancy in parts are mainly suitable for

retention whereas the greater level contribution of the ‘B’ trees are those to be

retained and protected also. Maintain clearance from ground level to lowest branches

retain and protect the existing soil levels and conditions for root growth.

3.2.3 Generally smaller scale, declining or limited contribution trees are categorised as low

quality ’C’ category trees. These may be suitable for retention for the most part but

should not present a significant constraint to the scheme as mitigation planting can

replicate and enhance their contribution.

3.2.4 ‘U’ class trees should be considered for removal for arboricultural reasons.

3.2.5 The removal of the above trees or vegetation may have an impact on the green cover

in the first instance, however, the scheme presents a significant enhancement

opportunity. Said removals would have no impact on the long term amenity of the

site and will allow for the selection of native species to enhance amenity and

biodiversity.

4. SCHEME / IMPLICATIONS ASSESSMENT

4.1 For this assessment, the proposed scheme has been considered (see; s.2.2 herein).

This includes consideration for arboricultural management / tree works for H&S tree

risk management, tree removal and pruning options, design solutions, tree

protection and sensitive measures to account for trees. As per s.1.6 and s.2.2 herein,

the TCP scheme overlay illustrates the proposed scheme.

4.2.1 Consideration for T11, T12, T18, T19 and T26 –

These trees are currently within the proposals footprint of blocks C and D and will be

required to be removed to accommodate the scheme. It is intended to mitigate the

loss within the landscaping scheme.

4.2.2 Consideration for T6, T7, T8, T9 and T10-

These trees are set withing the grounds of Sumner House and are separated from the

site by a brick-built boundary wall. It is also separated on site by an existing tarmacked

pedestrian walkway, also capable of taking light vehicles. The walkway is lit by street

lighting which was installed to the south of the walkway which required a service

trench to be excavated. Given the above the likelihood of significant roots from the

trees being within the RPA south of the walkway would be reduced.

The proposed footprint of Block B impinges on the unmodified RPA of T9 but given

the small percentage that is affected and the factors outlined above it is not likely to be

adversely affected by the scheme. It is not considered likely that significant roots will

be encountered where the proposed block is placed. The work to install the

foundations should be carried out by hand in the area indicated on the TPP. This

should be undertaken under Arboricultural supervision.

It is intended to protect the trees by a combination of retaining the existing hard surface

supplemented by tempory ground protection as outlined in the areas on the TPP.

Protective fencing is not considered necessary in this instance as the existing ground

conditions, tempory ground protection and existing wall are considered adequate

protection.

The ground level plan for the soft landscaping shows that that it is intended to retain

the existing ground levels in this area.

The trees are managed by pollarding on a regular basis and it is envisaged that this

practice will continue which eliminate any crown interference issues.

4.2.3 Consideration for T13-

Only proposed soft landscaping impinges on the RPA of T13. It is intended to

protect the tree by a combination of temporary ground protection and Heras fencing

as shown on the TPP. Only to be removed in the landscape phase

4.2.3 Consideration for T15-

Only proposed soft landscaping impinges on the RPA of T15. It is intended to

protect the tree as shown on the TPP by a combination of temporary ground

protection and the existing fencing in the locations shown. Protection to be removed

in the landscape phase.

4.3 Tree works -

4.3.1 Only those tree works previously mentioned as recommended H&S tree works are

proposed, as detailed within the tree works data table as ‘management’. No further

access enabling pruning work is anticipated

4.3.2 It is necessary for all tree works to be undertaken by a suitably qualified, experienced

and insured Tree Surgeon, prior to site works commencing, outside of nesting bird

season (or to have confirmation of no nesting birds by a qualified specialist).

5. METHOD STATEMENT ‘CONSIDERATIONS’

5.1 Arboricultural Construction Restrictions

5.1.1 The following restrictions are considered relevant for tree protection purposes

which are to be illustrated on a detailed Tree Protection Plan as part of planning

conditions:

a) Tree Works - are to be completed prior to any and all site works: no tree works not

specified within this AIA (or leaning against or attaching of objects to a tree) are

permitted unless agreed in writing by the council (subject to standard exemptions).

b) Tree Protection - Protective Barrier Fencing/ (Pedestrian Fencing) (PBF) is to be

installed in areas indicated within TPP (thick red lines) with works clearance, i.e.

1.5-2.0m around the hard landscape extents. Site compounds are to be away from

these areas unless on existing hard surface or where temporary ground protection is

used.

c) Construction Exclusion - the fenced off areas (indicated in red in the TPP are

Construction Exclusion Zones (CEZ). These areas should not be used for vehicular

access or storage as only manual work is to take place in these areas.

d) Site Restrictions - no chemicals/materials are to be transported/stored/used/mixed

within the CEZ, and no fires are to be lit and no machinery, plant or vehicles are to

be washed down within 10m of the tree’s canopy or in a CEZ

e) Lifting of existing Hardsurface- Phased lifting of the existing paved surface is to be

used in order to minimise the time that existing levels are exposed. Alternatively,

the existing paving could be lifted entirely and replaced with temporary ground

protection which could be removed/replaced depending on works required.

f) Ground Works/ Hard Landscape - During site works RPAs/CEZ there should not be

other none agreed works such as new surface works, new service installations

without the consultant’s prior advice and council consent, and no mechanical

digging or scraping is permitted within RPAs/CEZ; The new surface treatment is to

be installed by hand existing levels are to be retained.

g) Completion - only following construction and hard landscape completion can PBF

and stem protection be removed and remaining soft landscape works undertaken

within RPAs / CEZ (ground levels to be retained and works undertaken manually

with non-driven machinery).

5.1 Arboricultural Site Monitoring / Supervision

5.1.1 The council will typically request ‘a scheme of supervision for the arboricultural

protection measures’ to confirm tree protection and adherence to working methods

around trees.

5.1.2 The appointed site contractor and project manager will be provided with an

approved AMS and TPP and will need to be briefed as to prohibited works and tree

protection.

5.1.3 A record of each site visit will be kept, and a summary letter drafted for the client,

the site manager and the local authority (to be sent to the client for distribution),

thus -

• (1) Pre-commencement to confirm approved tree works, tree protection fence

line and construction restrictions for ground works;

• (2) Hand Digging Foundations The foundations for Block B in the area

indicated on the TPP will be hand dug

• (3) Half way through the programme to confirm maintained tree protection,

no tree damage and exclusion of RPA access;

• (4) After-construction to confirm excavations of existing hard surfaces, and

discuss tree protection requirements with the landscape team;

• (5) During soft landscape works for, retained soil levels and planting with

mulch layer;

• (6) Development completion after all hard landscape works and tree and

shrub planting is complete to sign off the site as having adhere to the AMS.

5.2 Ground Protection

5.2.1 In order to avoid the need for supplementary ground protection, phased construction

works are to be used in conjunction with the installation of the PBF; surface works

within retained trees’ RPAs are to be delayed until construction completion.

At the point of PBF being installed, the enclosed RPA sections become Construction

Exclusion Zones (hereafter; CEZ) to protect the trees’ rooting areas during

construction.

5.2.2 Where the retention of existing hard surfaces cannot be maintained within RPAs

during construction, temporary ground protection will be needed, i.e. for exposed

RPAs.

Specifically, the ground is to be protected from impact where it may be subject to

direct pedestrian/vehicular movements. The ground protection is to be appropriate

for the intensity of the pedestrian or vehicular movements thus -

a) For pedestrian movements within an exposed RPA, the ground protection is

to consist of “a single thickness of scaffold boards on top of a compressible layer laid

onto a geotextile, or supported by scaffold”; and

b) For wheeled or tracked movements within an exposed RPA, the ground

protection is to “be designed by an engineer to accommodate the likely loading”.

A specific proprietary ground protection system can be used as per the example

picture in the TPP

5.3 Underground utilities

5.3.1 Any new underground utilities are to utilise the construction area and hard surface

extents for new installations and avoid the need for works in proximity to trees.

Certainly, utility installations are to be:

• Located outside of RPAs and construction exclusion zones; and

• Installed only following the installation of the protective barrier fencing to

ensure the retained trees and their RPAs are protected.

5.4 Landscape Detail

5.4.1 The new tree planting illustrated on the current proposals will need supplementary

detail on species and nursery selection, planting method and maintenance.

5.5 Ground Works within RPAs

5.5.1 Any excavations within a RPA or designated CEZ (the area enclosed by PBF) must:

• Only be undertaken when the construction works are completed; and

• Use sensitive excavation techniques to protect the tree roots and their existing

growing conditions.

5.5.2 The excavation of existing surfaces are to be preventative and carefully avoid

damage to tree roots; i.e. individual 50mm layers of existing hard surfaces are to be

excavated at a time within an RPA/CEZ. This is to ensure that excavations do not

incur on the existing soil levels, i.e. no downward regrading of soil levels within

RPAs.

5.6 Report Handling

5.6.1 This report is released to the client and architect to be distributed at their discretion

and the consultant is available for queries relating to this report and/or trees.

5.6.2 The proposed scheme is reviewed in respect of the Arboricultural constraints and is

considered to be achievable in line with the BS5837 guidance.

5.6.3 This AMS and the TPP may be approved by the council in support of the

application.

5.6.2 This Arboricultural Report is produced to demonstrate consideration in reference to

BS5837 an may be approved by the council as a means of authorised tree protection

measures. This would be subject to an arboricultural review of the approved scheme

alongside details otherwise unavailable at the planning stages (construction site

layout, contractor’s site management plan etc.) whereby the AMS and TPP are to be

available on site and inspected as per s.5.2 for ‘Arboricultural Monitoring / Supervision’.

This concludes our advice.

Appendix II

Terms and Definitions

“Arboriculturist” - person who has, through relevant education, training and experience,

gained expertise in the field of trees in relation to construction.

“Competent Person” - person who has training and experience relevant to the matter being

addressed and an understanding of the requirements of the particular task being

approached.

“Topographical survey” - an accurately measured land survey undertaken to show all relevant

existing site features. A method of carrying out topographical surveys is given in RICS specification

Surveys of land buildings and utility services at scales of 1:500 and larger.

“BS5837 Tree survey” - should be undertaken by an arboriculturist to record information

about the trees on or adjacent to a site. The results of the tree survey, including material

constraints arising from existing trees that merit retention, should be used (along with any

other relevant baseline data) to inform feasibility studies and design options. For this reason,

the tree survey should be completed and made available to designers prior to and/or

independently of any specific proposals for development.

“Tree categorisation method” - trees should be categorised in accordance with the BS5837

cascade chart by an arboriculturist. This is to identify the quality and value (in a non-fiscal

sense) of the existing tree stock, allowing informed decisions to be made concerning which

trees should be removed or retained in the event of development occurring.

“Root protection area (RPA)” - layout design tool indicating the minimum area around a tree

deemed to contain sufficient roots and rooting volume to maintain the tree’s viability, and

where the protection of the roots and soil structure is treated as a priority, shown as an

arboricultural constraint in m². The radius is calculated using the BS5837 calculation

method. An arboriculturist may change the shape of an RPA but not reduce its area.

“Arboricultural implications assessment” - a study, undertaken by an arboriculturist, to

identify, evaluate and possibly mitigate the extent of direct and indirect impacts on existing

trees that may arise as a result of the implementation of any site layout proposal.

“Arboricultural method statement” - methodology for the implementation of any aspect of

development that is within the root protection area, or has the potential to result in loss of or

damage to a tree to be retained.

“Tree protection plan” - a scale drawing, informed by descriptive text where necessary, based

upon the finalised proposals, showing trees for retention and illustrating the tree and

landscape protection measures.

Approximate number of years a tree will continue to contribute without the need for oppressive arboricultural intervention, categorised in years as <10, 10-20, 20-40 and

>40; Structural and physiological condition observations;

Within the survey schedule denotes an estimate

Preliminary management recommendations (as appropriate);

BS5837 tree quality assessment category: resulting from structural/physiological condition and remaining contribution (approximate useful life expectancy);

Standard retention category U: in such a condition that any existing value would be lost within 10 years;

Standard retention category A: high quality and value, in such a condition as to be able to make substantial contribution of 40+ years;

Standard retention category B: moderate quality and value, in such a condition as to make a significant contribution of 20+ years;

Standard retention category C: low quality and value, currently in adequate condition to remain until new planting could be established 10+ years;

Standard retention sub-category, mainly due to: 1- Arboricultural values, 2- Landscape values, 3- Cultural values, including conservation;

On client request: presence of Tree Preservation Orders (TPO) / site location within a Conservation Area (CA) & date checked;

Tree reference number: tag or plan number (T - individual tree, G - group of trees/shrubs, H - hedge);

Genus, species and/or common name;

Age classification (NP - new planting, Y - young, EM - Early-Mature, SM - semi mature, M - mature, LM - late mature, OM - over mature);

Approximate height of tree in metres;

Approximate branch spread in metres of the four principal compass points;

Stem diameter in millimetres: measured in accordance with s.4.6 of BS5837;

Circle radius of the Root Protection Area: calculated using the stem diameter (single/multiple stem variant, as outlined within BS5837);

Crown clearance in metres above the adjacent ground level;

Clearance in metres to first significant branch and direction of growth (where relevant);

Physiological condition typically gauged from canopy cover and annual extension growth (good, fair, poor, dead);
