But supporters of Protect Our Woodland! - the campaign set up by local people to fight the plan - are calling on all those who support their fight to rally outside - and inside - the crucial meeting, which they fear will be nothing but a rubber-stamp for the developers.
The council planners meet at Worthing Assembly Hall at 6pm and POW! is urging protesters to be on the steps at 5.45pm to show their anger.
Said a spokesman: "We will be picketing the entrance to the meeting and hope to muster a strong and noisy presence inside. But because of the short notice we really need all those who sympathise to make an effort and support us."
People are urged to bring placards and banners etc as press will be there.
A message from POW! to its supporters said: "As many of you will know this development, if approved, will be built on the last remaining area of green field in Durrington, worst of all it will have a major impact on the unique Titnore ancient woodland and historic Titnore Lane.
"As this is possibly the only chance we will have to directly influence
the council's decision on this scheme, it is of the utmost importance that everyone, yes everyone attend that meeting, the Assembly Hall must be full to bursting.
"Please bring your friends, and forward this message on to everyone in
your address book and if possible post on websites."
Protest at 5.45pm, Friday June 10, Assembly Hall, Stoke Abbott Road, Worthing.
