West Yorkshire councils clash in housing development row
Leeds City Council is formally objecting to neighbouring Bradford City Council's plans to approve nearly 1,000 new homes.
The proposed housing is in the Menston area in the city, close to the boundary with Leeds.
Leeds council said it was concerned about the impact on the greenbelt and possible traffic congestion.
City of Bradford Metropolitan District Council said it had "no comment to make at this time."
The proposals are outlined in Bradford's Local Development Framework which sets out the council's development plan for the years leading up to 2026.
The report states that "Airedale and east Bradford (as part of larger area extending into west Leeds) are defined as areas of economic and housing growth."
The report proposes that 900 new homes could be built in Menston.
Leeds councillor Richard Lewis, the authority's executive member for city development, said: "This is strategic greenbelt territory. The cities are very close together at these points. We're very concerned that we maintain a green corridor between the cities.
"Quite rightly local residents are saying they're worried and are contacting us and we have our own concerns saying this is something that needs looking at. We do have our worries about any big ingress into the greenbelt in those areas."
Local residents have formed a protest group to campaign against the proposal and other planned developments in the Menston area.
Philip Moore from the Menston Action Group said: "There are all sorts of issues about the local roads, many of which are very narrow. Some of them you can't get two cars passing at the same time."
