He added that if the development went ahead, together with with recently announced plans for 2,500 homes, it would “cause unacceptable urban sprawl between Carterton, Brize Norton, Minister Lovell and Witney”.
Councillor Steve Cosier said he could not support the plans.
“We are always talking about water, sewage, infrastructure, and all of us sing from the same hymn sheet when we say it isn’t good enough,” he said.
The proposals also include improvements to Kilkenny Lane Country Park, and contributions towards healthcare, education and a new cemetery and woodland burial site.
Laura Bisbey, who spoke behalf of applicant Harper Crewe Bloombridge, said the plans would include measures to improve the flood risk situation downstream.
She also said the company would agree to deliver an interim private sewage network in the event that Thames Water do not resolve the issues with the network.
There were also four supporting comments in favour of the development, with neighbours saying that the added housing could unlock more community resources, and that more homes were needed.
The plans were approved, with four councillors voting in favour, two councillors voting against and six abstaining.
