The local planning authority is Broadland District Council and communication with the Council’s Planning Department confirms that there are no Tree Preservation Orders in the immediate vicinity and that there is no Conservation Area in this part of Lingwood. There are no high quality category “A” trees on the site, and all the trees are located on the perimeter of the site. One young conifer and a section of Lonicera hedge are required to be removed to make space for the development. No significant impacts on the retained trees are anticipated Recommended root protection areas are mapped in this report. No construction activities should take place within root protection areas, except as indicated in the detailed method statement. We consider that development can be accommodated with minimal impacts on the arboricultural interest of the site. 16th December 2018 4 South Burlingham Road, Lingwood - Arboricultural Report v1.0.docx 1. INTRODUCTION 1.1. BH Trees and Woodland Consultancy Ltd has been commissioned to prepare an arboricultural report for land at “Rowan”, South Burlingham Road, Lingwood, Norfolk, Norfolk . 1.2. The current site access is located at grid reference TG 36980 08985. 1.3. The report includes a survey of those trees that may be affected and an assessment of the potential arboricultural impact of the proposed development on the trees. 2. METHODOLOGY 2.1. The tree survey and arboricultural aspects have been prepared in accordance with recommendations provided in BS 5837:2012, Trees in relation to design, demolition and construction – recommendations. 2.2. The site survey included trees, within the boundaries of the site and those considered to be potentially affected by development proposals, with a stem diameter over 75mm at 1.5m height. 2.3. The tree inspection took place from ground level using visual tree assessment methods, with the use of binoculars and Suunto clinometer. The presence and condition of bark and stem wounds, cavities, decay, fungal fruiting bodies and any structural defects that could increase the risk of structural failure were noted. 2.4. Details for each tree were recorded with management recommendations if deemed necessary for the development requirements, a category grading according to BS 5837:2012, and tree protection distance. Constraints 2.5. No internal decay devices or other invasive tools to assess tree condition were used. 2.6. No soil excavation or root inspection was carried out. 2.7. The survey has not considered the effect that trees or vegetation may have on the structural integrity of future building through subsidence or heave. 16th December 2018 5 South Burlingham Road, Lingwood - Arboricultural Report v1.0.docx 3. DESKTOP REVIEW 3.1 The proposed development site is located in the small village of Lingwood. Lingwood and Burlingham is a civil parish in the English county of Norfolk, comprising the large village of Lingwood together with the smaller villages of Burlingham Green, North Burlingham and South Burlingham. The villages are all within 4 kilometres (2.5 mi) of each other, some 15 kilometres (9.3 mi) equidistant from the town of Great Yarmouth and the city of Norwich. 3.2 The development proposal is for the extension of the existing bungalow to incorporate a garage and some internal alteration. This will include a new access off the public road and a car parking/turning area. 3.3 The local planning authority is Broadland District Council and communication with the Council’s Planning Department confirms that there are no Tree Preservation Orders in the immediate vicinity and that there is no Conservation Area in this part of Lingwood. The Site Figure 1. Site location 16th December 2018 6 South Burlingham Road, Lingwood - Arboricultural Report v1.0.docx 4. FIELD STUDY 4.1 The trees on the site are plotted on a plan shown in Figure 2 below. A schedule of the detailed survey data is reproduced in a table at appendix A. 4.2 The property “Rowan” is located on a quiet rural lane. It is a small bungalow with a loft conversion and an old timber garage. The development proposal affects only the area to the north and west of the existing building. This area is currently used as the landscaped front garden of the bungalow. The main area affected has a surfacing of crazy-paving over a large part. 4.3 The tree interest in this area is a collection of semi-mature, exotic, ornamental species. There is a low close-trimmed roadside hedge consisting of mainly Lonicera and holly, which continues along part of the eastern boundary in a less tended form. 4.4 The soils in this area are generally freely draining slightly acid loamy soils, thus of low fertility but moderately resistant to compaction. The site stands in The North East Norfolk and Flegg National Character Area (NCA 79) which slopes gently from west to east and is divided into three parts interspersed by The Broads National Character Area. Inland it is a rich agricultural area with small- to medium-scale fields, and is mainly unwooded. Isolated farmsteads and small nucleated villages with large medieval churches are linked by a dense network of lanes. 4.5 The site stands in a very rural location on the edge of the built up area. Views from the public road are currently available over the low existing hedging along the roadside. It is considered that the proposed development would cause minimal visual intrusion which can be mitigated by care with the design and suitable landscaping proposals. 16th December 2018 7 Figure 2: Tree Survey 9th November 2018 8 South Burlingham Road, Lingwood - Arboricultural Report v1.0.docx Figure 3: Tree Protection Plan 16th December 2018 9 5 ASSESSMENT OF ARBORICULTURAL IMPLICATIONS 5.1 The Tree Survey plan in figure 2 shows the trees found on the site and their quality assessment according to the grading categories stipulated in the British Standard. 5.2 There are no trees awarded a high category “A” grading. Two trees are given a moderate category B grading as promising specimens but possibly in the wrong position as one is very close to the overhead wires and the other very close to the road. The remaining trees are awarded a category C grading largely due to their poor condition and limited expected future contribution. The cascade chart for tree quality assessment from BS5837:2012 is reproduced in appendix D. 5.3 The hedgerow along the road is established but poorly structured and composed predominantly of Lonicera, a vigorous pioneer species but lacking stem strength to achieve a tall hedge without support. It is proposed to create a gap in the hedge for the new access. The hedge presumably once extended the full length of the western boundary but the northern section has been replaced with a wooden panel fence. 5.4 It is proposed to remove the redwood tree to create the access driveway to the new garage. The access has no other impacts. There is some minor encroachment on the rooting zone of the larch tree T3 where the turning area for the drive extends to the west. It would be preferable to create a shorter wider hammerhead. However, this area is already covered with a hard surface crazy paving and set a lower level than the root collar of the tree. Therefore if the new surface is created without further excavation and protected from compaction with a load bearing layer, any impact can be minimised 5.5 Table 1 –Quality assessment of trees recorded in survey in accordance with BS5837:2012 TOTALS To be Trees Groups Hedges removed Category U 1 0 0 1 1 Category A 0 0 0 0 0 Category B 2 0 0 2 0 Category C 6 0 1 7 1 TOTALS 9 0 1 10 2 9th November 2018 10 South Burlingham Road, Lingwood - Arboricultural Report v1.0.docx 6 ARBORICULTURAL METHOD STATEMENT Tree Work 6.1 No tree work is recommended or proposed other than the possible removal of T8 category U tree. 6.2 Any tree work should be undertaken to the standards set out in BS 3998:2010 British Standard Recommendations for Tree Work. Tree and Root Protection – Constraints on Development 6.3 The Tree Constraints Plan in Figure 3 shows the distance that construction should normally be kept away from retained trees to provide the Root Protection Area (RPA) recommended in BS 5837: 2012.
