1. Introduction

a. Overview

This Method Statement is intended to ensure the successful protection and retention of trees during

the demolition and construction works for the proposed residential extension and renovation at

Holden Clough, Lancashire.

The method statement should be used in conjunction with Tree Report; reference Holden Clough

27_03_12 and guidance from the Local Authority Arboricultural Officer. All works are to be undertaken

to current best practice and in line with recommendations contained in BS5837:2012

b. Site Description

The survey area comprises the immediate surroundings of the property Holden Clough. This area

consists of established gardens, un-maintained amenity tree plantings and semi-natural woodland.

Holden Clough is a detached country house, the eastern aspect of the property is towards open

maintained lawned areas, to the south a steep banking descends to the watercourse, this banking

has mature tree cover of both native and non-native species. The gardens to the rear (west) of the

property are bounded by an area of un-maintained woodland, tree stock in this area mainly comprises

of mature non-native conifers with additional self seeded native broadleaf individuals.

The north of the property comprises of a group of semidetached outbuildings leading to the entrance

driveway. This driveway is bounded by further plantings of non-native conifers. Many areas of the

survey site and wider surrounding area would appear to have been planted with coniferous

specimens during the 19th century, a large number of these trees are now showing significant defects

or are in poor locations for their present size.

See Tree report Appendix1, Appendix 2 for detailed tree list and existing site layout details.

c. Proposed Development

To the best of our knowledge the current development proposal undergoing design consideration is

for the renovation of the existing house and the replacement of the dilapidated two storey outrigger

wing. Associated works will be undertaken to landscsape the gardens to the rear of the property and

to replace the existing underground water supply pipes supplying Holden Clough village and a

number of other properties.

2. Tree Preservation Orders and Conservation Areas

a. Site Description

We understand that the site is not covered by a Tree Preservation order, nor is it within a

conservation area. The status of all the trees on the site would need to be confirmed and appropriate

permissions obtained prior to any works being undertaken on the surveyed trees, as listed in

Appendix 1: Tree Schedule.

ref HoldenClough_AMS_19/08/13

3. Timetable

a. Overview

A detailed schedule of monitoring and management visits is attached in Appendix 4

Prior to commencement of constuction phase the following actions should take place to ensure

protection of trees on site.

1. Site meeting between main contractor/architect, project arboriculturalist and Local Authority Tree

Officer. To discuss arboricultural issues relating to demolition and construction phases.

2. Erection of protective fencing and ground protection prior to demolition phase.

3. Tree work/removals between completion of demolition phase and comencement of construction.

4. Management of site during development / construction phase as per guidance detailed in this

method statement

To follow specific guidance notes in section 8. and arboriculktural inspection schedule.

5. Landscaping of site as per guidance detailed in this method statement.

4. Tree surgery work

a. Proposed Tree Removals

Trees proposed for removal due to poor condition or defects are shown on the tree protection plan in

the colour red and are referenced as follows. T1, T8, T9, T18, T20, T24, T25, T26.

Note: T8 is scheduled for removal after demolition phase but prior to construction of new retaining

wall on river banking. This is due to the poor strcuctural condition of thsi tree and its position on th

banking above the watercourse.

b. Proposed Tree Work

No tree works in direct relation to the proposed development are identified in the Tree Report Holden

Clough 27_03_12 but note should be taken of recommendations in the same associated tree report

Appendix 1 with regards to management of all trees on site. Tree references T4 and T5 have

recomended remedial works (T4 removal of epicormic growth), these works are not however directly

related to the proposed development

5. Protective fencing

Once erected all protective fencing will be regarded as sacrosanct and will remain in place until the

completion of the construction phase. It shall not be removed, relocated or breached at any time

without consultation with the project arboriculturalist.

Protective fencing will be constructed of robust barriers fit for the purpose of excluding demolition and

construction traffic form root protection areas. Details of appropriate fencing types are included in

Appendix 2.

Signs will be affixed to every third panel stating ‘Tree Protection Area Keep Out’. See Appendix 3 for

example of signage.

Positions for protective fencing are indicated in Appendix 1: Tree Protection Plan

ref HoldenClough_AMS_19/08/13

6. ConstructionPhase

a. Principles to avoid damage to trees.

Once installed tree protection must remain in place and be observed at all times.

No fires within 10m of the crown of any retained trees.

No changes in soil levels should take place in tree protection zones.

No cement mixing/washout to take place within 15m of any retained trees.

No chemicals, bitumen etc to be stored within 10m of any retained trees.

Any spillage of fuel, chemicals or contaminated water occurring within 2m of the root protection

areas to be reported to project arboriculturalist.

b. Specific guidance - Tree references T2

To protect this tree during the demolition and construdtion phases and to ensure its continued vaibilty

within the proposed development we recommend that the the following guidance be used.

1. Erection of RPA protective screen at the position indicated upon the Tree Protection Plan (TPP),

this screen is to protect the stem and crown of T2.

2. Due to the presence of the main site access and subsidary access to the north of T2 a requirement

exists for vehicle movement within the calculated RPA of T2 .

3. A layer of 100mm depth hardcore / crusher run will be placed in the areas indicated on the Tree

protection plan to reduce ground compaction from construction traffic.

4. Any lifting of existing cobbled surfacing in the yard shall be undertaken by hand.

5. Post construction decompaction via air spade technique following the removal of protective

hardcore detailed above.

6. Any resurfacing of the existing driveway in the RPA of T2 should maintain the porous gravel

surface and be on top of the exitsing surfacing with no mechanical removal of the existing surfacing

in the RPA of T2.

c. Specific guidance - Tree references T4 to T21

To protect these trees during the demolition and construdtion phases and to ensure there continued

vaibilty within the proposed development we recommend that the the following guidance be used.

1. Erection of RPA protective screens at the position indicated upon the Tree Protection Plan (TPP).

2.Position of protective screen to protect T21 to be positioned at the top of steep banking separating

wooded area from lower lawned area

ref HoldenClough_AMS_051012

7. Services/Utilities

Routing of replacement water supply pipes.

1. A requirement exists for the replacement of the existing water pipes supplying water to Holden

Clough village.

2. The route of these water pipes will pass through the edge of the calculated RPA of T2. Tree

refrence T1 and adjacent minor trees are marked for removal due to poor condition and identified

defects so will be unaffected by any trenching in this area

3. In this area all excavation shall be undertaken by hand.

4. If roots are encountered in this area the following steps should be undertaken. If roots under 25mm

are encountered they may be careful pruned. Any roots over 25mm shall be carefully hand

excavated, moisture retained by wrapping in damp hessian, roots then to be repositioned to outside

edge of excavated area and covered with graded topsoil. All work to be supervised by project

arboriculturalist.

5. The route of the replacement water pipes does not pass through any further RPA’s until it

approaches the footbridge over the watercourse. At this point the water pipe will follow a route to be

marked by project arboriculturalist and main contractor which follows the line of the existing

pedestrian footpath. Trenching in this area wil be by hand digging.

8. Landscaping

Landscape operations within tree protection zones have the potential to damage trees if not carried

out with care. In addition the removal of protective fencing to carry out landscaping operations may

allow other contractors into previously protected areas.

All landscaping will avoid soil re-grading and disturbance within tree protective areas where possible.

If cultivation of the soil and making up of levels is required, cultivation should not exceed 50mm depth

and must all times be by hand. All landscaping works, soft and hard should be carried out as the last

process of development.

An additional requirement for the removal of Japanese Knotweed along the northern bank of the

water course has been identified. We understand that removal of the top layer of topsoil by hand is

required as part of this process. This process should not impact upon retained trees in direct relation

to the proposed development, care must be taken to avoid root disturbance in the RPA of T4. If any

roots are encountered or exposed during this process they should be covered immediately with clean

topsoil.
