Campaigners will meet on Tuesday morning to voice their objections to the plan.
Hellingly families have also been urged to lodge their comments online with Wealden District Council at WD/2026/1679/MAO. The closing date for submissions is October 2.
Campaigners argue the scheme ‘will transform the historic Hellingly village forever as 280 households will choose to use a single lane, medieval track Mill Lane, as a rat run onto the A267 avoiding the schools.
‘Two hundred and eighty houses will also mean the flooding Hellingly already experienced in the winter will get worse..’
Developers, London based Hallam Land, state the scheme follows a 'logical settlement pattern' north of Hailsham and would create a new neighbourhood with its own distinct character.
