1.0 GENERAL 1.1 This tree survey was undertaken on behalf of Gleeson Homes in conjunction with a proposal for

residential development on site:

• by Martin Popplewell (Landscape Architect) and Jon Cocking (Arboricultural Consultant) on 17 Mar 2015 (items 1-37.

• Robert Armitage (Ascerta) on 05/05/2015 & 06/05/2015 (items 38-43) 1.2 The survey should be read in conjunction with drawing 2547/1B (Existing Trees on Site). 1.3 The study site is located on the extreme northern edge of the village of Hapton which lies

4.8 km west of Burnley town centre. It is bounded to the west by Manchester Road beyond which lie – at a distance - a row of terraced dwellings. To the south the site is bounded by the Leeds and Liverpool canal beyond which lie various land uses – woodland, a caravan storage area and an area of housing. To the north and east lies open ground – flat grassland to the North and recent planting on a substantial mound (around 10 m high) to the East.

1.4 The site was formally in industrial use but all buildings on site have now been demolished. The

ground is primarily hard surfaced (tarmac and concrete), the remaining areas are covered in self sown plants and rough grass. Ground is almost level across the majority of the site at around 150 metres Above Ordnance Datum (AOD). Towards the northern edge of the survey area levels fall away either as steep banking or low retaining walls. Beyond the site boundary to the north and west ground levels fall gradually away whereas to the South (beyond the Leeds and Liverpool canal) ground levels rise within the village of Hapton. The most striking change of ground level is to the east where a significant mound (around 10m high) has been recently been created on reclaimed land.

1.5 The local planning authority has confirmed that no trees within the survey area are protected by

Tree Preservation Order nor does the site fall within a Conservation Area. 1.6 Trees grow and can develop weaknesses, the climate is thought to be changing and the many

other factors which affect trees are rarely static. It is advisable to have trees inspected by a qualified arboriculturalist regularly, and in this instance it is recommended that these inspections should be made every year.

1.7 The report is based upon a visual inspection. The consultant shall not be responsible for

events which happen after this time due to factors which were not apparent at the time, and the acceptance of this report constitutes an agreement with the guidelines and the terms listed in this report.

1.8 Any defects seen by a contractor or the employer that were not apparent to the consultant must

be brought to the consultant’s attention immediately. 1.9 No liability can be accepted by the consultant in respect of the trees unless the

recommendations (see Section 9) are carried out under their supervision and within the timescale indicated.

1.10 The report aims to consider both the aesthetic qualities of the trees as well as their health. The

health of the trees is considered in relation to the proposed change of use to housing.

1.11 It must be noted that this tree report and accompanying drawing(s) do not constitute a Schedule of Works, and approval should be sought from the local authority prior to any works commencing.

2.0 SPECIES AND THEIR ARRANGEMENT IN THE LANDSCAPE 2.1 The trees surveyed are found in several distinct groups. Firstly there is an area of, mostly self

sown, planting along the southern site boundary (adjacent to the wall that separates the site from the Leeds and Liverpool canal); some of these form an area of sucker growth that extends into the site somewhat. Secondly there is a substantial area of planting towards the Northern edge of the site; much of this surrounds an area of ground that was a formal a garden area associated with a property now demolished. Thirdly, there are substantial blocks of semi-native species that have been planted to the north and east of the former factory site as part of a remediation exercise.

2.2 The planting along the southern site boundary includes Birch, Grey Poplar and Goat Willow. 2.3 The planting within the Northern part of the proposed development site includes both tree

species – Sycamore, Willow, Red Chestnut – and shrub species – Hawthorn, Holly, Privet and Rhododendron.

2.4 Planting as part of the remediation work includes Oak, Aspen, Spruce, Birch, Crack Willow,

Hawthorn, Wild Cherry, Alder, Hybrid Poplar, Lombardy Poplar and Goat Willow.

3.0 HEIGHT AND SIGNIFICANCE IN THE LANDSCAPE 3.1 The most visually significant trees on site are those within the woodland area G31 - specifically

the double line of Sycamore that runs along its northern edge (G31a). These trees are both significant in height (up to 15 m high) and form a single block of vegetation; they also lie atop a low wall so appear elevated when viewed from the north.

3.2 Of the remaining trees within the former factory site the most significant in visual terms are

those along the southern boundary. Although the trees in this group are only 11-12m high they form a single group and are readily visible from the tow path that runs along Leeds and Liverpool canal so do have some significance in landscape terms.

3.3 The remaining trees on the proposed development site, i.e. those that lie alongside the access

road from the west, have some visual significance from within the site but are relatively insignificant in the wider landscape.

3.4 The blocks of semi-native species that have been planted to the north and east of the former

factory site as part of a remediation exercise are relatively modest in height so have little visual impact at the present time though these have potential to develop into significant features over time.

4.0 AGE AND CONDITION 4.1 Trees on site range from young through semi mature or mature. This age split results from the

former group being either recently planted or self sown specimens with the latter group having been planted at a similar time around the garden of the former dwelling.

4.2 The majority of trees are in fair to good condition and no work is recommended at this time on

arboricultural grounds.

5.0 ENVIRONMENTAL CONDITIONS 5.1 Due to their location on level ground at a slightly lower level in comparison to land to the south

trees on site would not be expected to be subject to potential adverse impact from prevailing winds. Indeed, there is no evidence of this at the present time and the presence of woodland planting both the north and on a substantial new mounded area immediately to the east is likely to provide increasingly sheltered conditions for trees on site as this planting matures.

5.2 Ground water conditions are also not assessed to be a significant factor in present or future

growth or health of trees due to the underlying sloping nature of the ground.

7.0 TREE QUALITY ASSESSMENT 7.1 TREES UNSUITABLE FOR RETENTION Definition – Category U (Shown in broken outline on drawing with cross at trunk location) Those in such a condition that they cannot realistically be retained as living trees in the context of the current land use for longer than 10 years. Criteria – Category U Trees that have a serious, irremediable, structural defect, such that their early loss is expected due to collapse, including those that will become unviable after removal of other category U trees (e.g. where, for whatever reason, the loss of companion shelter cannot be mitigated by pruning) Trees that are dead or are showing signs of significant, immediate, and irreversible overall decline. Trees infected with pathogens of significance to the health and/or safety of other trees nearby or very low quality trees suppressing adjacent trees of better quality. NOTE: Category U trees can have existing or potential conservation value which it might be desirable to preserve; 7.2 TREES TO BE CONSIDERED FOR RETENTION Definition - Category A1, A2, A3 (Shown in heavy outline on drawing with star at trunk location) Trees of high quality with an estimated life expectancy of at least 40 years. Criteria - Category A A1 (Mainly arboricultural qualities) Trees that are particularly good examples of their species, especially if rare or unusual; or those that are essential components of groups or formal or semi-formal arboricultural features (e.g. the dominant and/or principal trees within an avenue). A2 (Mainly landscape qualities) Trees, groups or woodlands of particular visual importance as arboricultural and/or landscape features. A3 (Mainly cultural values, including conservation) Trees, groups or woodlands of significant conservation, historical, commemorative or other value (e.g. veteran trees or wood-pasture).

2547 Manchester Road, Hapton: Tree Survey Rosetta Landscape Design 2015

8

Definition - Category B1, B2, B3 (Shown in medium outline on drawing with solid dot at trunk location) Trees of moderate quality with an estimated remaining life expectancy of at least 20 years. Criteria - Category B B1 (Mainly arboricultural qualities) Trees that might be included in category A, but are downgraded because of impaired condition (e.g. presence of significant though remediable defects, including unsympathetic past management and storm damage), such that they are unlikely to be suitable fore retention for beyond 40 years; or trees lacking the special quality necessary to merit the category A designation. B2 (Mainly landscape qualities) Trees present in numbers, usually growing as groups or woodlands, such that they attract a higher collective rating than they might as individuals; or trees occurring as collectives but situated so as to make little visual contribution to the wider locality. B3 (Mainly cultural values, including conservation) Trees with material conservation or other cultural value. Definition - Category C1, C2, C3 (Shown in light outline on drawing with open circle at trunk location) Trees of low quality with an estimated remaining life expectancy of at least 10 years or young trees with a stem diameter below 150mm. Criteria - Category C C1 (Mainly arboricultural qualities) Unremarkable trees of very limited merit or such impaired condition that they do not qualify in higher categories. C2 (Mainly landscape qualities) Trees present in groups or woodlands, but without this conferring on them significantly greater landscape value; and/or trees offering low or only temporary/transient landscape benefit. C3 (Mainly cultural values, including conservation) Trees with no material conservation or other cultural value. NOTE: Whilst C category trees will usually not be retained where they would impose a significant constraint on development, young trees with a stem diameter of less than 150mm should be considered for relocation.

9.0 GENERAL RECOMMENDATIONS 9.1 Generally Any recommended tree works should only be carried out with the consent of the local authority. 9.2 Trees in relation to Development Consider the depth of foundations with reference to NHBC recommendations. 9.3 Tree Work before Development Remove all ‘U’ category trees including those approved for removal in relation to approved

development. Erect a robust fence to protect not only the retained trees themselves, but also the rooting zones at limit of canopy spread or in accordance with BS 5837:2012.

9.4 Care of Trees during Development It is recommended that the precautions below be issued to the site manager for display on site. GENERAL PRECAUTIONS DURING DEVELOPMENT: • Section 4.6 of British Standard 5837:2012 “Trees in Relation to Construction” gives details

of the method for calculating the root protection area (RPA - based on stem diameter) which should be left undisturbed around each retained tree. This is to prevent soil compaction, stacking etc. during demolition/construction. The RPA is included on the Tree Constraints Plan together with an indication of Above Ground Constraints.

• Based on the above calculation, and taking into account site specific issues, fencing in accordance with BS 5837:2012 should be erected around trees to be retained. This shall comprise a framework of scaffold poles driven vertically into the ground with diagonal bracing for support and welded mesh panels wired to uprights. This must be erected before any site access for demolition or construction. The above details and distances of tree protection will normally be set as a condition of any planning approval.

• British Standard 5837:2012 provides guidance for methods of working on development sites in proximity to retained trees and the principles set down in Section 7 of the document should be strictly adhered to. The following principles are particularly important:

• Traffic must not enter tree root protection areas.

• Stacking of construction materials should not occur beneath any tree canopies or within tree root protection areas.

• Cement mixing or flushing should not occur inside minimum tree protective zones or within 10m of any tree (including trees on adjacent properties).

• Fires should not be lit within 10m of any tree/canopy (this distance should be increased if conditions are windy).

• Toxic materials (cements, oils, etc) should not be stored beneath canopies or within tree root protection areas.

9.5 Towards Conclusion of Development Surgery is best carried out at this stage so that any known root damage can be corrected by

the appropriate crown thinning to restore root/shoot balance. Similarly, trees now seen in relation to garden situations can be shaped as required. Planting to augment existing trees as part of the landscape works can now be appropriately undertaken at this stage.
