Samuda Estate, Westferry Road, London E14.

A Report in fulfillment of conditions attached to Planning Permission PA/10/01300

19/01/2011

1.0 Introduction On 22nd June 2010 Nathaniel Lichfield & Partners, with Farrer Huxley Associates submitted an application to the Tower Hamlets Planning department for external environmental refurbishment/enhancement works to Samuda Estate E14. Tower Hamlets granted conditional permission for development on 27 October 2010. See Appendix 1 for copy of the letter outlining conditions. This report has been submitted to satisfy the details of Condition 4 as set out in Permission PA/10/01300. This relates to existing trees and their protection during construction in accordance with BS 5837 (2005). Appendix 2 of this report contains all the relevant drawings in A3 format. 2.0 Tree survey In December 2010 Farrer Huxley Associates (Project Landscape Architects) commissioned Arbtech Consulting Limited to complete a tree location and condition survey with advice on tree protection areas in relation to the proposed construction works. The proposed works at Samuda comprise the following environmental works:

• Playground refurbishments at Kelson House and Dagmar Court • Installation of community gardening facilities at Hedley House. Adjacent the

community centre • Installation of refuse stations to facilitate the proper disposal of recycling, refuse

and bulk waste and to tidy the streetscape. • General landscape refurbishments such as replacement of broken pavers,

repairs to tarmac estate roads, and painting existing railings. • Arboricultural works

The environmental works are confined to limited areas of the application site (Samuda Housing Estate) and trees in sections of the Estate beyond these areas will be unaffected by the proposed works. As agreed with Council Officers prior to submission, only those areas of the Estate within the vicinity of the proposed works have been surveyed and these are illustrated on drawing 0179 Samuda Estate – Tree Constraints Plan TCP 04/4 by Arbtech Consulting Limited. Trees in the remainder of the Samuda Estate will not be affected by construction works, therefore survey and tree protection will not be required. Arbtech arboricultural consultants carried out the tree survey in accordance with BS 5837 (2005) – Trees in Relation to Construction and produced the survey recording location, details of tree species, dimensions and condition. (Refer to Appendix 2 for items 0179-Tree Constraints Plan & 0179-Survey Sheet for tabulated list of species, dimensions and condition).

Arbtech included information regarding root protection areas, for trees in vulnerable locations relating to the proposed works. The locations of the recommended tree protection fencing are shown on FHA drawings P492-02-CN-60 & P492-02CN-61. NOTES:

a) Tree survey and tree protection plans have been plotted using the available OS base mapping.

b) Protective fencing will be erected only around trees likely to be affected by disturbance/construction works.

c) All levels in the vicinity of the existing trees and within their RPA will not be subject to any alterations as a result of the proposed environmental works.

d) In line with the submitted planning application, trees on the estate are to be retained wherever possible. As a result of the Arboricultural Survey a small number existing trees have been identified as dead, dying or severely damaged. It is therefore the intention of Island Homes Housing Association to remove these trees in the interests of public safety. The trees to be removed are illustrated on the submitted plans and the arboricultural justification for their removal can be found in the Arbtech 0179-Survey Sheet.

Trees to be removed are as follows:

• Kelson house - G24:C1. 1no. Acer platanoides (the northern-most of the two trees in this group) is to be removed and replaced. “Significant bark damage and one tree is outgrowing its metal guard”

• Dagmar Court – T57:C1, T58:C2 &T 59:C1. 3no. Malus spp Rosaceae trees

are to be removed and replaced “Significant bark wounds from strimmer and vandalism”.

3.0 General notes on Tree Protection Adequate protection, both above and below ground, is essential for trees that are to be retained as part of a development. The British Standard BS5837: 2005 Trees in Relation to Construction Recommendations gives advice for ensuring that the negative impacts of development on trees are minimised. The guidance recommends that there should be a root protection area (RPA) around trees which is kept free of all construction activities by means of an exclusion zone enforced through protective fencing or ground protection. The RPA is calculated as the area equivalent to a circle with a radius of 12 times the trunk diameter at a height of 1.5 m above ground level. The guidance recommends that the root protection area should be protected by means of fencing and/or ground protection.

Figure 1. Diagram to illustrate design of protective fencing

The proposed root protection zones have been based on the values calculated for root protection area and are illustrated on the Arbtech plan TCP0179 . These plans are included in Appendix 2. Fencing will consist of a scaffold framework (not wooden posts), well braced to resist impacts, with vertical tubes spaced at a maximum interval of 3 m (Figure 1). Onto this, weld mesh panels or 2m high shuttering board will be securely fixed with wire or scaffold clamps. Weld mesh panels on rubber or concrete feet will not be used as these are not resistant to impact and are too easily removed by site operatives.

High visibility all weather notices will be securely attached to the barriers around protection zones with the words as shown in Figure 2 below. Where long lengths of barrier are erected a sign will be attached at intervals of no less than 6 m. Figure 2. Wording to be included in high visibility all-weather sign attached to protective fencing

No toxic materials will be stored within the root protection zone (e.g. oil, diesel) and no mixing of potentially toxic materials (e.g. cement) will be carried out within the protection zone. Within the protection zone no operations or changes in level may take place. Note clause 8.4.2 BS 5837: 2005 for activities which are forbidden. Where work within the canopy is unavoidable the minimum protection zone can be calculated using table 1 of BS 5837: 2005 and reduced by up to one third on one side only following instructions from the landscape architect or arboriculturalist. If temporary vehicular access or scaffolding is required within a protected area, clauses 8.3.1 and 8.3.2 shall be observed of BS 5837: 2005. All excavation works within the protected area shall be carried out by hand. Trenches for footings should be kept as narrow as possible. Existing ground levels around the excavations should not be disturbed.

Only after all operations on site have been completed will fencing and ground protection be removed in order to allow final landscaping. Please refer to the Appendix 1 for Tower Hamlets Planning letter; and Appendix 2 for all relevant Arbtech and FHA drawings.

TREE PROTECTION PRIOR TO COMMENCEMENT ON SITEAll tree protection should be erected prior to any operations,demolition, or commencement of any construction. Protective fencing should be erected as shown on this drawing. Fencing to be well-braced and robust, min. height 1200 and compliant with BS 5837.Trees indicated are to be felled prior to commencement of operations on site. Treesfor felling to be agreed with CA on site and marked. Trees are to be felled in accordance with BS 3998.Trees to be felled that are adjacent to, or that lie within a continuous canopy of trees to be retained, should be removed with particular care. In some cases a tree may have to be removed in sections to avoid damage to adjacent trees to be retained.Some trees are to be cut back where branches are vulnerable. Branches shall be shortened back to a fork, in accordance with BS 3998.Trees should not be used as anchorages for equipment used for removing stumps, roots or other trees or for any other purpose. When this is unavoidable, the trees should be protected in accordance with the recommendations of BS 3998.Should root pruning be required within the protected area, it shall be carried out under B.S reference 3998in the following way: Roots shall be cut so that the final wound will be as small as possible and free from ragged, torn ends. Ifthe root forks, the final cut should be made to remove one arm of the fork. All tools used for cutting shouldbe sharp and clean in compliance with BS 3998 Appendix B.Following pruning exposed roots should be immediately covered with a 50 / 50 sand / topsoil mix.The line of protective fencing, can only be breached if necessary for carrying out works below the tree canopy. In this situation additional lengths of protective fencing must be erected to allow the minimumspace for the works to be undertaken, the precise location is to be agreed on site with the CA. The originalprotective fencing must be reinstalled in the same position once the work beneath the canopy is complete.

TREE PROTECTION DURING OPERATIONSWithin the protection zone no operations or changes in level may take place. Note clause 8.4.2 BS5837: 2005 for activities which are forbidden. Where work within the canopy is unavoidable the minimum protection zone can be calculated using table 1of BS 5837: 2005 and reduced by up to one third on one side only following instructions from the landscape architect or arboriculturalist. If temporary vehicular access or scaffolding is required within a protected area, clauses 8.3.1 and 8.3.2 shall be observed of BS 5837: 2005.All excavation works within the protected area shall be carried out by hand. Trenches for footings should be kept as narrow as possible. Existing ground levels around the excavations should not be disturbed.
