CAMPAIGNERS are reeling after being told they cannot build a children's hospice on a field near the M62.
Kirklees Council planners gave the thumbs-down after visiting the site near Old Lindley Moor.
They ruled that there was no overwhelming reason to lift a ban on new development in the Green Belt.
Officials at West Yorkshire Forget-Me-Not Trust confessed they felt "deflated" after the decision.
But senior fundraiser Mandy Barwick promised: "Our work as a charity goes on. We are determined to get this much-needed children's hospice."
The location - just yards from the M62 - came under fire at a Huddersfield Town Hall meeting.
Councillors said children would suffer from traffic noise and air pollution.
Fundraisers are now looking at appealing against the decision or scouring the area for another site.
But they fear they could be outbid by property developers on sites zoned for building.
Supporters have raised £500,000 towards a seven-bed hospice and respite centre.
The trust aims to raise £4m for the hospice, which will serve 280 families in Kirklees and Calderdale.
Councillors said they were sympathetic, but the site off Old Lindley Road was the wrong place.
Labour's Clr Annie Smith, chairman of the council's area planning committee, admitted: "This job on the planning committee can be awful at times.
"But I honestly do not believe that a hospice here would be in the best interests of the children."
Councillors have told their estates staff to help in the search for suitable land.
Tory councillor Ken Sims said he agreed that the Old Lindley Road site was not the right one.
"The noise and air pollution from the motorway is horrendous," he added.
The charity was established in 1998 by Ainley Top mother Linda Senior, whose son, Russell, was suffering from a brain-related illness.
It is now run by a full-time team based at an office in Elland.
Fundraisers have included Huddersfield Town footballers, women's groups, firefighters and Wooldale Co-operative Society.
