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.
