0.1 CONSTRUCTION METHOD STATEMENT

Existing Parking (Blue area on plan) Small Contractor’s vehicles will be parked on site. (Existing House vacated) Larger / Heavy vehicles will not access the site. Sequence of works Demolition of the existing retaining wall, construction of new entrance, parking forecourt and foundation reduced levels to be undertaken by specialist ground works contractors. It is anticipat-ed that a detailed method statement for these works will be made a condition of a planning approval. Loading and Unloading (Pink area on plan) Larger delivery vehicles will be offloaded on the highway area to the site frontage. The local highway authority/Police will be requested to suspend parking in London Road for the length of the frontage to No.67. Deliveries will be managed to avoid vehicles queuing on the main highway. Storage of plant and materials A secure compound area (Heras type fencing) will be provided (grey area on plan). The method statement for the appointment of the groundworks contractor will include the provision for Road Sweeping/Cleaning as required to ensure the safety of road users. Security Hoarding The existing site boundary walls, fence and mature hedgerow and protective fencing will be utilised to secure the site perimeter together with heras fencing to the road frontage/access. Dust and Dirt The development envisages utilising dry construction for substantive elements of the build. The foundations are designed to minimise the need for excavation. Water spraying and other tech-niques will be used by the contractor to minimise the formation and spread of dust, to mitigate any nuisance to adjoining residents. Skips will be covered to prevent dust and dirt being spread by wind, and collected on a regular basis. Recycling and Disposal of Waste The collection of general waste will be the responsibility of a licensed waste contractor who will dispose of it to a licensed waste recycling facility. On-site fitting out works will employ specialist contractors who will be responsible for recycling useable waste materials. Statement for Deliveries Deliveries will be minimal as follows: Storage space has been pre designated and is prepared for materials, deliveries utilising existing areas of hard standing. The site deliveries are to be minimised with known lead in delivery times used to ensure that material quantities stored on site are minimised. A banksman will be on hand to intercept and guide large delivery vehicles, and to ensure that existing fences and trees are not damaged and that people are warned of vehicle movements. Forklifts will be under the supervision of the banksman, forklifts are to have reverse warning sig-nals and flashing lights. Manual handling of materials is to be by trained persons only, heavy items are to be assessed to determine the safest way of moving them. High visibility clothing to be worn at all times. As Vehicles deliveries are to utilise the existing hardstanding area to the highway frontage then additional safety precautions are to be put in place to ensure the safety of site personnel and other road users when materials are being unloaded.

DRAINAGE STRATEGY Incorporates the implementation of sustainable drainage methods (SuDS) in accordance with best practice and the proposed national standards. Drainage strategy for surface water run-off from the site which prevents the discharge of surface water from the site into the public system. Permeable paved areas are designed and constructed in accordance with Manufacturer's guidelines. Permeable areas are constructed on a permeable sub-base material such as Type 3 or reduced fines Type 1 material as appropriate. In accordance with good practice and planning guidance, all roof areas, perimeter hard paving and access track to Garage and outbuilding are ALL specified as SUDS or drained to Soakaway. ACCESS /HARDSTANDING - CROSSOVER The reconstructed access crossover from London Road will be finished in bitmac with a linear slot drainage is specified to accommodate the anticipated water run off into a crate soakaway and will delineate the edge of the highway curtilage (site boundary)

Hard Standing Area

SW SOAKAWAY Rainwater will discharge into a new soakaway, minimum 1m² in area and minimum 1m deep below the lowest incoming pipe. Soakaway to consist of soakaway crates fixed to-gether to manufacturer’s instructions and surrounded with a geotextile lining to prevent entry of fines materials. Actual size to be determined by manufacturer following porosity test on site as required by Building Control. The soakaway is to be minimum 5m from any building foundations and located away from the existing highway . Size/Capacity of the Soakaway is to be based on LABC guidance of roof/paving area in sqm /50 as the volume required. The soakaway crates are to be installed as manufactures recommendations wrapped in a filter membrane.

Planting and protection; Planting to be in accordance with BS4428:1989 between Nov and March Hedgerow shrubs are to be trench planted to a min depth of 400mm and width of 600mm.All plants are to be well heeled in after planting and watered in during dry weath-er. Planting between November and March (avoiding very cold or wet weather). The planted hedge is to be protected by the use of rabbit netting to protect from rodent damage (approx 3-5 years before removal). Min 75mm Bark Mulch will be used to aid water retention and prevent perennial weeds out-competing the developing roots. Mixed Hedgerow species (boundary to No.65 & No.67 Rear Garden) Viburnum Opulus—Guelder Rose Crataegus monogyna—Hawthorn Corylus avellana—Hazel Ligustrum Vulgare—Privet Pyracantha SP—Firethorn Hedgerow species to frontage;(no.67) Fagus Sylatica—Beech hedge Planting; Bare Root 120-150cm plants 5 Plants/m in double stacked rows 33cm between plants and 40cm between rows Maintenance Programme; Weed control will be undertaken by the applicant as part of normal property maintenance.

Decorative native tree planting; The proposed native species mix below is proposed to enhance support for local wildlife and provide more interest to the site boundary by including 4no. new trees to the existing boundaries. The new trees will consist of; T1 Acer Campestre, Field Maple T2 Betula Pendula - Silver Birch T3 Crataegus laevigata 'Paul's Scarlet', Hawthorn T4 Pyrus Avium, Cherry The approximate location of the 4 trees is identified on the landscape plan. The actual locations will be chosen on site considering views, privacy screening and site constraints (soakaways & access). Each tree will be extra heavy standard (14-16cm) in size and have a clear stem structure. The trees are to be container grown and planted via an underground guying system or similar.

SOFT LANDSCAPE MAINTENANCE

Maintenance Programme; Weed control will be undertaken by the applicant as part of normal property maintenance. Formative pruning: In winter, just after planting, and for the first two years after planting Maintenance pruning: Each summer Pruning is to encourage a bushier and denser hedge by cutting at least 2 cm above the previous year's growth. This keeps the hedge full of vigour and growth. Hard pruning of young plants encourages growth of lower branches, making the hedge dense from the base. Each winter remove at least half of the new seasons growth. The sides of the hedge should taper slightly towards the top to allow light and rainwater to reach lower foliage and the ground at the base. An ideal cross section is a flat topped 'A'. An area at the base of each tree of 1.5m diameter in area and the hedgerow is to be kept free from rank grass and weeds for a period of 3 years following planting.

SOFT LANDSCAPE TREE MAINTENANCE

Tree Maintenance Programme; Individual trees shall be planted as follows: Trees should be planted in areas previously cleared of weeds, grass and vegetation. The trees are to be of Extra Heavy Standard (14-16cm) in size, container grown and healthy and vigorous. Trees should be planted in planting holes 1.2m x 1.2m x 900mm deep, with the topsoil mixed with a minimum of 20li-tres of suitable tree planting compost and replaced carefully around the roots and lightly compacted every 150mm layer. Trees should be supported with underground guying sys-tem or similar and protected from rabbit damage as per the adjacent hedgerow planting. Planting: After root-balled plants are set at the proper level in holes all cord and wrapping shall be untied from the trunk base. All plants shall be backfilled with topsoil. All plants shall be thoughly watered at the time of planting to prevent air pockets and settling. At the time of planting, trees and shrubs shall be pruned using generally accepted horticul-tural/ arboricultural methods (Ref to BS 3998). All plastic material, string, and containers shall be removed at time of planting. The plastic liners of container grown trees must be completely removed. Mulching: Aged shredded hardwood bark, pine bark, or aged wood chips can be used. Mulch shall be applied around all plants to minimum depth of 75mm and a maximum of 100mm over entire planting pit. Maintenance: shall include pruning, cultivating, mowing, fertilising, watering, and applica-tion of appropriate pesticides necessary to maintain plants in healthy condition. Inspection: shall be undertaken regular to ensure that the plants are well established and healthy—with any plants which die within the 1st planting season being replaced.
