Formby's Labour MP Bill Esterson has written to Sefton Planning Committee to oppose the controversial plans to build a housing estate on green belt land off Liverpool Road.
Bill is urging everyone in Formby to submit their views to the planning committee regarding the plans ahead of the deadline next Monday (September 9).
David Wilson Homes & Barratt Homes have submitted an application to build 274 dwellings on land off Monks Drive, Savon Hook, River Close and Liverpool Road.
In his letter to the planning committee, the MP raised concerns about the plan's impact on Formby's infrastructure.
Bill wrote: "Residents have raised with me their concerns about the impact on Formby of the additional traffic which will be generated as a result of the development. I would therefore ask that the committee considers whether the road system will be able to cope with the additional traffic generated and whether the road layout to and from the Formby bypass will need to be re-modelled for reasons of either safety or congestion.
"Another major issue raised is the impact on drainage. There are already problems with the drainage and with surface flooding in Formby. Will the infrastructure be able to avoid increasing the risk of flooding?
"The current local plan indicates no development in the green belt.
"Can the infrastructure of Formby cope with the addition of 300 households eg for school places and GP places?"
In his letter, Bill also called on the Planning Committee to ensure that any housing developments must guarantee affordable housing for existing Formby residents as he wrote: "Will the planning committee ensure that a proportion of the affordable housing being built is allocated to people living in and around Formby?"
Bill said: "This is an application that has huge repercussions for Formby and the whole of Sefton.
"There are a number of concerns about the impact of this development on the wider community of Formby and its infrastructure.
"I, and the many residents who have contacted me about this issue, want to know that new house building is in the interests of the existing community of Formby. We need to know that the people of this community can benefit from any affordable houses that are built here.
"There are many questions about the impact of the development. Any plans that are approved will need to address what are very real concerns about traffic, about drainage and about the impact on the wider community of this development and the loss of green belt."
