Development classed as 'designated' requires particular scrutiny because of its nature or potential environmental impacts. Designated development includes development that has a high potential to have adverse impacts because of their scale or nature or because of their location near sensitive environmental areas. Schedule 3 of the Environmental Planning and Assessment Regulation 2000 lists designated development types.

All Designated Developments must be advertised for a minimum period of 30 days and in accordance with the special advertisement procedures listed in the Environmental Planning and Assessment Regulation 2000.
