A site visit to consider the controversial application for 370 houses in East Ardsley has been postponed by Leeds City Council.
The planning inspector was due to visit the Church Field site this week but it has been postponed to a date later in the month.
Church Fields campaign co-ordinator Wyn Kidger said: “We are disappointed at the decision to postpone the site visit.
“We were geared up to bring residents together on Thursday morning to show the strength of opposition to this housing application.
“It is clear to residents that local roads, schools and health centres will be overwhelmed if this application was to go ahead. We wanted to send a clear message that we are all united against this unnecessary housing application.”
The letter from the planning inspector casts doubt on the LDF plan and questions whether the council has enough sites to provide a five year land supply for housing.
Coun Kidger said: “The release of greenfield sites such as Church Fields is unnecessary and allows developers the option of avoiding regenerating brownfield sites that need to be improved but gives them the right to rip up precious local greenfield sites.”
