FEARS of flooding are likely to halt a third bid to build homes on an abandoned mill site in Huddersfield.
Neighbours refused to believe the Environment Agency when it said there was no risk.
So they went to the expense of getting their own expert to look at the plan for Spa Mills, Spa Bottom, Fenay Bridge.
And his findings helped to turn councillors against the scheme yesterday.
Two previous bids to build homes have been rejected.
People living in the area say their claims about the flooding risk have been consistently ignored by the Environment Agency.
Adrian Ratcliffe, spokesman for an action group concerned about the handling of planning applications involving a flood risk, said: "Without the massive amount of time and money given by local people, an inappropriate development on a flood plain could have been approved at the first committee meeting."
In the latest scheme, developers want to build between 50 and 70 homes on the site.
Objectors now have to wait for a final decision by councillors at a town hall meeting on December 17.
Mr Ratcliffe said: "Early evidence provided by local residents should have rung alarm bells for the various agencies much sooner.
"We intend to make further representations when the recommendation for refusal is considered by the Planning and Highway Committee on December 17."
Battling residents were supported by two MPs - Huddersfield's Barry Sheerman and Wakefield's David Hinchliffe, whose constituency includes the Kirkburton area.
Supermarket group Morrisons, which has a store near the site, said development would remove an eyesore.
