Councillors are set to give the go-ahead to the final design of a planned housing development in Longridge. Outline planning permission was granted for the site on Whittingham Road back in 2015.   The developer is now seeking approval of the detailed specification for the western half of the plot – including two connections to a neighbouring estate which is currently under construction. Preston City Council’s planning committee will be told that 30 percent of the 83 homes planned for the site are to be classed as affordable.   They will also be scattered throughout the development, as required by a local planning policy designed to promote social inclusion. The estate – which will include a mix of 3 and 4 bedroom detached, semi-detached and terrace styles – has attracted objections from several members of the public and also Whittingham Parish Council.   But a report to be presented to councillors says that concerns, including an increase in traffic and a lack of public transport in the area, were taken into account earlier in the planning process. All of the homes will have their own off-street parking facilities – either garages or driveways – but the highways authority, Lancashire County Council, requested “a number of amendments to the road layout of the development to ensure the road is built to adoptable standards”, the report notes. The application also finalises a planned area of open space on the estate, which will be centrally-located and accessible from the main road running through the development. The housebuilder intends to retain the existing hedgerow which borders the site and most of the trees and hedgerows contained within in it.   However, the developer has been told to resubmit its tree-planting plans “to clarify the trees to be retained and removed”. Officers have recommended councillors approve the application – the planning committee will decide when it meets on Thursday afternoon.
