Trees
Trees provide a wide range of benefits including helping to tackle climate change by absorbing carbon dioxide, reducing pollution, providing vital habitats improving our quality of life, health and wellbeing and providing and creating more aesthetically pleasing environments. Trees are rightly a material consideration within the UK planning system.
A detailed survey of all existing trees at and adjacent to the site has been undertaken and the proposed development has been carefully designed in consultation with an Arboriculturist. All trees of merit can and will be retained within the proposed site layout and particular attention has been given to the retention of trees adjacent to the site boundaries to provide screening and/or soften views of the proposed development from neighbouring residential properties and the adjacent public roads and footpaths.
There are opportunities to improve, diversify and increase the tree population at this site by planting individual and groups of trees as well as the creation of a community orchard. A harmonious relationship between trees, dwellings and people can be achieved and sustained in the long term at this site.

Biodiversity
The site is comprised of predominantly low value habitat for protected species, notably cropland across most of the site. The hedgerows and trees on site are of significance to nature conservation and will be retained and buffered as much as possible. The adjacent woodland, of high ecological value, to the northwest of the site has been well buffered and avoided.
The proposed development offers ecological improvement on the site via a range of planting methods including new hedgerows, trees, an orchard, attenuation basins and rain gardens which will enhance the sites suitability for a range of protected and notable species. Large areas of the site will remain as open green space, providing beneficial opportunities for a range of faunal groups, including bats, nesting and foraging birds, mammals, insects and reptiles. At least 10% Biodiversity Net Gain will be achieved.
A sensitive lighting scheme will ensure that light levels are kept low for any commuting bats and nocturnal animals.

Heritage
There are no designated or non-designated heritage assets within the Site.
Situated to the north of the Site is a grouping of ‘Locally Listed Buildings’ associated with Canons Farm. The proposed development has been carefully considered in order to provide a suitable set back from the farmstead and sensitive landscaped areas in order to minimise any potential impacts that may arise to the heritage significance of these non-designated heritage assets as a result of a change in ‘setting’.
The only designated heritage asset situated within the environs of the Site is Legal and General House, a late 1980s/ early 1990s former office headquarters designed by Arup located c.250m southeast of the Site. On site assessment and a review of the design of both the building and the designed landscape does not indicate that views in the direction of the Site formed part of the design intent of the asset.



Highways
The vehicular access to Canons Lane will be outlined in detail and assessed as part of the planning application to ensure it is safe and robust from a technical perspective. The highway along the northern part of Canons Lane has been assessed and deemed suitable to serve the site; our technical assessment estimates that there will be an estimated 47 cars per hour leaving the site in peak hours (heading north on Canons Lane) and that this amount of traffic increase can be accommodated.
The layout of the development will be designed to prioritise pedestrians and cyclists and connect into the existing links to surrounding areas via Canons Lane and Copt Hill Road, providing connectivity on foot or cycle to local facilities, including Kingswood train station. The existing public right of way which runs diagonally through the site will be retained.
A Framework Travel Plan will be submitted with the planning application and provide proposals on types of measures that could be implemented to further reduce vehicle-based trips from the development and outline targets to achieve meaningful modal shift in line with the vision we will set out in the Transport Assessment.

Flooding & Drainage
The site is located entirely within Flood Zone 1 (low probability). The vast majority of the site has a very low yearly chance of surface water flooding, in line with future climate change projections. There are three small areas with a low to high yearly chance of surface water flooding; these are likely due to localised low spots on site and would be mitigated through the onsite levels design.
Surface water generated by the development would be attenuated using sustainable drainage systems (SuDS) in the form of an attenuation basin. The basin would also provide water quality, biodiversity and amenity benefits. Flows would then infiltrate into the ground.
Foul flows would drain to the existing Thames Water foul sewer network to the north of the site along Ballards Green.
