Arboricultural Impact Assessment & Method Statement – Land off Pen Y Ball Hill, Holywell (14/09/2021) © Tree Solutions Ltd (2021) 2

1.0 INSTRUCTION 1.1 We have been instructed by Leason Homes to carry out an Arboricultural Impact Assessment

(AIA) in order to assess the development proposal in relation to trees in accordance with the principles of British Standard 5837 ‘Trees in Relation to Design, Demolition & Construction - Recommendations’ 2012.

1.2 We are instructed to prepare a report in order to provide information to assist all parties involved

in the planning process to make balanced judgements regarding arboricultural features in relation to the proposed development on land off Pen Y Ball Hill, Holywell. As such, all trees within influencing distance to the development proposals both on and adjoining the site have been surveyed and are listed within a Tree Survey Schedule (Appendix 1) and plotted on all accompanying plans.

1.3 The phase 1 tree survey was carried out on 06/09/2021 by Alistair Henderson, Principal

Consultant to Tree Solutions Ltd. Our appraisal of the mechanical integrity of trees on the site is enough to inform the current project. The assessment of trees is carried out from ground level without invasive investigation and the disclosure of hidden defects cannot therefore be expected. Details relating to trees located outside the site boundary are estimated as site access was not permissible. Whilst the survey is not specifically commissioned to report on matters of tree safety, we report obvious defects that are significant in relation to the existing and proposed land use. We do not carry out detailed safety inspections unless specifically instructed to do so in writing and have not carried out such inspections of trees on the proposal site.

1.4 Five individual trees (T1-T5) and two groups (G1-G2) were surveyed and mapped on a

Preliminary Tree Constraints Plan and Impact Assessment Plan Ref: 21/AIA/Flints/71, Drawing Nos. 1&2 at Appendix 2/3. All arboricultural information recorded during the survey is presented within a schedule at Appendix 1.

1.6 The Arboricultural Impact Assessment is based on the site plan Ref: 16.5690/B2 provided by

Parry Davies Architects. 2.0 STATUTORY CONTROLS 2.1 A search on Flintshire Council's interactive map on 06/09/2021 revealed that a number of trees

on and adjoining the site are subject to a Tree Preservation Order. Having assessed the schedule and map within the TPO (see below), it is unclear what trees are protected as they appear to be no longer present.

Plate 2 – Extract from TPO map showing location of protected tree

2.2 Protected Species 2.2.1 Mature trees often contain cavities, crevices and hollows that offer potential habitat for species

such as bats and barn owls. Both are afforded protection under the Schedule 5 of the Wildlife and Countryside Act 1981 (as amended). Bats are also protected under The Conservation of Habitats and Species Regulations 2010 (as amended). Refer to Ecology report for further details.

2.3 Wildlife Habitats 2.3.1 Trees and hedgerows of most species provide valuable nesting sites for a wide range of birds

and it is likely that nesting birds will be present on the site during the period March to September. 3.0 THE SITE 3.1 The site is a vacant building plot located to the north of Pen Y Ball Hill. Vehicular access is

proposed via Coed Y Fron to the NE.



4.0 DEVELOPMENT PROPOSAL 4.1 1 No residential dwelling with associated vehicular access and parking. 5.0 GENERAL CONSTRAINTS DATA - CONSTRUCTION EXCLUSION ZONES (CEZ’s) 5.1 GENERAL

5.1.1 The three phases of an AIA were outlined in Section 1. In addition, during the development

process for retention trees, there may be three and even four constraints to consider: Construction Exclusion Zone (CEZ’s):

• CEZ 1: Root Protection Area (see 5.2) • CEZ 2: Tree Crown Protection (see 5.3) • CEZ 3: Tree Dominance (see 5.4) • CEZ 4: New Tree Planting Zone (see 5.5)

CEZ’s are explained below: 5.2 CEZ 1: ROOT PROTECTION AREA (RPA) 5.2.1 The RPA, calculated in m2, should be protected before and during any demolition/construction

works. This ensures the effective retention of trees by safeguarding a reliable quantum of functioning tree roots. The RPA is based on a radial measure from the centre of the tree stem, which is calculated by multiplying the stem diameter by a factor of twelve or by the (mean stem diameter²) x number of stems for multi-stemmed trees. With the AIA 1, the RPA is only shown indicatively on the preliminary TCP, as its shape may be subject to amendment as the design progresses.

5.2.2 During the AIA 2, the derived radial measure is converted by the arboriculturalist into the actual

area to be protected, having due regard to prevailing site conditions and how these may have affected the tree(s), particularly in relation to factors affecting their likely rooting disposition. The RPA for each tree should initially be plotted as a circle centred on the base of the stem. Where pre-existing site conditions or other factors indicate that rooting has occurred asymmetrically, a polygon of equivalent area should be produced. Modifications to the shape of the RPA should reflect a soundly based arboricultural assessment of likely root distribution.

5.2.3 The means of protecting the RPA will include the installation of tree protective fencing prior to the

start of any demolition or construction work on site. The prohibition of various activities within the RPA must be adhered to (e.g. mechanical excavation, soil stripping, fire lighting, material storage, lowering levels and creating excessive sealed surfacing) and may include the use of temporary ground protection and/or special engineering solutions where construction is proposed near to retention trees or within the RPA.

5.3 CEZ 2: TREE CROWN PROTECTION ZONE 5.3.1 This is the area above ground occupied by the crown (branches) of the tree, along with

allowances for working space (safe working area) and if appropriate, for future growth. The extent of CEZ 2 is determined by considering the existing and future crown spread of the tree(s), bearing in mind the possibility of this being modified by an acceptable quantum of pruning.

5.4 CEZ 3: TREE DOMINANCE ZONE 5.4.1 Trees are located along the northern boundary and as such will not cast significant shading to the

rear gardens or elevations. All properties will benefit from unimpeded daylight from the south and west. The trees are fastigiate in form and the canopies do not overhand the rear gardens ensuring both property and trees can co-exist with no future pressures to fell or prune.

5.5 CEZ 4: NEW PLANTING ZONE 5.5.1 In some cases, it may be appropriate to identify and protect areas intended for new landscape

planting, which can fail to establish if the soil has been heavily compacted or contaminated during the demolition/construction process. The means of protecting CEZ 4 will either be by fencing it off prior to the start of works on site, or by soil remediation once construction has finished (and prior to the start of planting).



6.0 SURVEY METHODOLOGY 6.1 The method used in the preparation of this report is based on the principles of BS 5837: 2012.

1. Tree heights were surveyed to the nearest 1m. 2. Trunk diameters were measured by use of forestry girth tape 3. The category assessment (Table 1) on which the trees is based include current and long-term

arboricultural, landscape, cultural and conservation values (BS5837: 2012). This table can be found at Appendix 1

4. For clarity, the grading system is summarised from Table 2 of the BS as follows:

U grade – trees for removal, effective for less than 10 years A grade – trees of high quality and value, effective for more than 40 years B grade – trees of moderate quality and value, effective for more than 20 years C grade – trees of low quality and value, effective for 10 years Note: We have indicated colour coding on the drawing and therefore a monochrome copy should not be relied on.

6.2 SOIL ASSESSMENT

6.2.1 A soil assessment should be undertaken by a competent person to inform decisions relating to:

• the root protection area (RPA) • tree protection • new planting design; and • foundation design to take account of retained, removed and new trees (potential soil

subsidence/heave) Tree Solutions do not undertake soil assessments and the client is advised to seek specialist advice in this respect.

7.0 JUXTAPOSITION OF TREES AND STRUCTURES 7.1 Below ground constraints 7.1.1 The below ground constraints are generally summarised as the root protection area (RPA). The

shape of the RPA and its exact location will depend upon arboricultural considerations including likely tolerance of the tree to root disturbance; morphology and disposition of the roots when known influenced by past or existing site conditions; soil type and structure; and topography and drainage.

7.1.2 The purpose of the RPA is to prevent physical damage to tree roots and to prevent damage to

the soil structure. Tree roots are damaged by soil compaction, changes in soil levels or soil contamination which could reduce tree health and/or stability.

7.1.3 Root patterns are affected by topography and characteristics of the soil or substrate. Where trees

are located within proximity to existing hard standing or underground physical barriers, they are unlikely to have an even distribution of lateral roots due to restrictions in root growth created by compacted sub-grades beneath. The RPA of all trees have been plotted unmodified as there were no significant underground barriers present to prevent good radial root spread.

7.2 Underground Services 7.2.1 We have considered the broad implications of the provision of underground services but the

locations of existing and proposed were not identified on the plans supplied by the Project Architect and in this regard, our advice is of a general nature.

7.2.2 Drainage and service runs may need to be constructed within the rooting areas of retained trees.

If this is a requirement of the development it will be necessary to retain significant roots and methods of excavation, such as thrust boring or hand digging, may need to be adopted to ensure that these impacts are acceptable.



7.2.3 As with foundation design, low impact construction methods for services installation are now well established. For more information regarding underground services, reference should be made to the National Joint Utilities Group (NJUG) Publication No. 10. Volume 4 ‘Guidelines for the Planning, Installation and Maintenance of Utility Services in Proximity to Trees’ 2007.

8.0 DEVELOPMENT IMPACT TO TREES 8.1 Tree Solutions carried out a phase one preliminary tree survey and provided the project architect

with a report in which all existing trees and their respective Root Protection Areas (RPA) were identified and plotted on a tree constraints and indicative impact assessment plan. We are satisfied that the proposal has taken the long-term future of the most important trees into account and the layout is therefore in accordance with Flintshire Council Planning Policies and recommendations contained within BS5837: 2012.

8.2 In order to accommodate the proposed development it will be necessary to remove tree numbers

4, 5 and G1. These are small insignificant trees of no existing or future viability to the site. They offer no amenity or landscape value to the wider area as they cannot be seen from any public space. As such, they have been categorised as ‘C’ grade i.e. unremarkable trees with very limited merit and having no material conservation or other cultural value. Such trees should not form a material consideration of planning.

8.3 There is one construction impact to retained trees as listed below:

1. The driveway encroaches within the RPA of tree numbers 3. The impact of installing the driveway will have minimal impact to the future health and vitality of the tree as the site ground levels are lower than those around the tree. As such, in order to comply with the provisions of the BS the driveway will be installed to a no-dig design specification using a three-dimensional cellular confinement system such as ‘Infraweb’ or 'Cellweb' which will involve the installation of a 150mm layer of plastic cells. The cells will be back filled with a free draining washed stone that contains no fines in order to help maintain adequate gaseous diffusion for tree roots below. The top dressing will be a porous material such mono block to be agreed with the LPA. This specification complies with recommendations contained within para. 7.2 of BS5837: 2012. Specific design details are to be submitted by the structural engineer for approval, we have however provided an example cross section drawing below.

P1 – Small section of unmanaged boundary hedgerow to be removed for new access

P2 – Northern boundary, much of original hedgerow has been removed

P3 – T3 (Oak) & G1 (Hawthorn hedge & Sycamore stump)



9.0 PROPOSED REVISIONS TO THE SCHEME

9.1 We advise that all proposed revisions having implications for trees should be referred to us for

review. 10.0 CONCLUSIONS 10.1 BS 5837: 2012 contains clear and current recommendations for a best practice approach to the

assessment, retention, and protection of trees on development sites. The proposed development has followed this guidance by: Seeking arboricultural advice and undertaking a phase 1 preliminary tree survey in order to

inform the layout and design of the proposed development Respecting the constraints posed to development of the site by high or moderate quality trees

and amending the design accordingly Acting upon arboricultural advice throughout the design process in order to obtain the best

development proposal whilst considering the current and future tree requirements No significant trees are proposed for removal Taking the above into consideration we can see no valid Arboricultural grounds for refusal
