Dear Mr Parry
15/00837/OUT
I would like to add a further comment but this time on behalf of the prospective occupants of the proposed 180 houses that might be built west of Langford Brook and north of Gavray Drive.  I see from the your list of neighbours on the CDC public access documents that there are several factories. Since the removal of hedges and trees and the widening of the railway line by Chiltern (both east-west and to London) I and others have become aware of a vibration which can be heard from midnight onwards until 7 am running intermittently most of the night, even at weekends. It sounds like a very large pump or perhaps a metal beater.
The people in this new estate will not only hear high speed trains running until midnight but also noise from factories. Some of the houses will be occupied by young families with acute hearing. I think that you should definitely carry out noise checks 24/7 as so much of the infrastructure has changed since the last one was done. The upgrade to the railway has created a channelling for noise through to residental housing. Thick hedges (as there was once) make an effective noise barrier. However, I understand from Carillion that Network Rail will not allow any such planting near the new high speed railway.
I do wonder whether the site is a good place to squeeze on 180 houses. In my opinion it would be preferable to recreate it as an Open Green Space for people to exercise their dogs and themselves,  and for children to run wild in on foot (no bikes, especially motorised quad bikes). It could not be a formal Nature Reserve but would act to take pressure off other green spaces of which there never seems to be enough in Bicester. Bicester Fields is full of dogs and people and runners. We do need more green space. We could make it a wild flower meadow for Bicester Garden City.
In reply to Gallagher assertion  that the new Estate will prevent flooding downstream, I think that a far nicer, more ecological way would be to put a meander in the Langford Brook where the water table is highest shown by the flooding every winter.  A reed bed could be made  here for reed and marsh warblers. The middle pond in Bicester Fields has been very successful in this respect although the birds are being killed off by cats. I have seen a Little Egret last winter on the flooded part of the field west of Langford Brook (land referred to as 15/00837/OUT herein) and it stayed there for some weeks. Reed beds are documented to be very effective at absorbing pollutants, carbon dioxide and excess water.
