This site is not related to the existing village and would impact the setting of Hainford hall which is a listed building, The size and position is disproportionate and outside the development boundary and in conflict with the parish plan.
The area highlighted is already a known site liable to surface water flooding, because of the high water table. The current sewer system is unable to cope with the houses that already exist and it is difficult to comprehend whether the pipes/ pumping station can handle any more properties being connected. I remember two companies going bust when it was first installed, so the cost to update and increase capacity alone would be considerable and would make the cost nonviable as a project.
Hainford lacks a suitable infrastructure to support this level of development, we constantly suffer power cuts, the sever system is always blocking, there is no real practical bus service for the working people, with the bus company already struggling to justify the service now. Your own policy suggests that there should be a pavement from all areas of the village to the primary school, which there isn't which is in conflict with the service village status you propose
The roads in and around Hainford lack the capacity to support increase traffic movement, being single track with passing spaces in most cases. Loss of rural amenity
