Hundreds of people have joined the fight to stop houses being built on a long-established recreational area in Woodhall Spa.
Developers Waterloo have submitted an application to East Lindsey District Council - who also own the land - for a social housing complex on the Rally Field off Alexander Road.
However, they are facing strong opposition from residents.
More than 100 people staged a ‘camp out’ last Friday night at the proposed site.
An additional 500 residents have signed a petition, calling for the application to be scrapped.
Campaigners say the Rally Field is a “vital and much needed community asset” which has been an accepted part of the Jubilee Park complex since the 1950.
John Finley, a spokesman for the Friends of Jubilee Park, said they were “overwhelmed” by the response from residents.
He said: “We have been blown away by the level of support. Clearly, a lot of people don’t want this to happen and we are going to do everything we can to make sure it doesn’t.
“I want to make it clear this is not that no-one is against social housing, but there are far more suitable sites within Woodhall Spa.”
The Rally Field has been utilised for a host of different events and purposes, including overflow car parking for the highly successful 40s Festival.
Woodhall Spa Parish Council was due to hold a meeting with Waterloo today (Wednesday).
Local district councillor Craig Leyland said he understood why feelings were running high and admitted he ‘had sympathy’ with residents.
However, he said it was a complicated matter, not least because Waterloo’s bid for a nearby site had been held up by a village green application.
