Hundreds of Aintree and Melling residents showed their opposition to proposals to build on the greenbelt at a demonstration at Aintree Youth Centre on Monday evening.
The demonstration coincided with an extra Core Stratgey drop-in session organised by Labour Molynuex Ward Councillors Tony Carr and Marion Atkinson to give residents the chance to quiz Sefton Council planning officers.
Residents young and old attended, many armed with placards and banners to make their feelings known.
Cllr Carr, who was on hand to speak to the residents, said: "We organised the extra drop-in event on behalf of the residents after we held three extremely well attended public meetings on the Core Strategy in Molyneux Ward. Residents felt disappointed by the consultation process so we arranged the extra drop-in session so they could put their feelings directly to the council officers.
"People attending the drop-in session and the demonstration were extremely concerned that developers were being given the ability to build on greenbelt and greenspace in East Sefton. They fear for the impact on local wildlife and on the local infrastructure.
"Sefton planners heard directly from residents that some of the sites earmarked for potential development are clearly not appropriate.
"A number of resident even presented the planning officers with their own reports to argue against building on the sites. In their turn, planners gave assurances that all such evidence, once verified, will add weight to the case for rejecting proposals to build on the sites."
Cllr Carr said the Tory-Lib Dem government was making it far too easy for developers to build on greenbelt and greenspace.
Cllr Carr said: "Having read the Tory-Lib Dem Government's recently published planning document, all cases for rejection of planning applications must be robust.
"Concerningly, the document states, 'decision-takers at every level should assume that the default answer to development proposals is yes' - a very frightening scenario which offers developers priority over local planners and residents. If this is their idea of big society then my feelings are quite clear that this government places a higher priority to corporate influence than that of the general population. This is wrong on so many levels.
"But what we are seeing in Molyneux, East Sefton and throughout the borough is the real Big Society standing up and letting this government know that they have gotten it wrong again."
