No approval has been given so far for a high-rise condominium project on the green stretch opposite Shamrock Beach in Batu Feringghi.
But residents are worried that the council may eventually approve the project. Following howls of protest, the project was scaled down from 37 storeys to 22 storeys.
The MPPP issued notices to neighbouring residents on 6 September giving them three weeks to make any objections.
The council must make public the gradients of the hill-slopes in the area as the state government had said there would be no more projects on Class 3 and 4 slopes.
