Crawley Borough Council’s Local Plan is to be scrutinised by inspectors who will then decide whether or not it is suitable to be adopted.
Work on the plan – known as Crawley 2030 – started in January 2012.
Once it is adopted it will shape the future development of the town for 15 years.
The Examination in Public will be held in the council chamber at the town hall from Tuesday (March 17) until Friday March 27.
If approved by independent planning inspector, Martin Pike, the plan is scheduled to be adopted in October or November.
Among the matters to be discussed will be: whether the Local Plan is legally sound, whether it has correctly calculated the housing and employment needs of the borough, whether it can deliver on what it offers and whether it has balanced the need for growth with the need to protect the environment.
Members of the public are welcome to attend the hearings.
