This spatial dataset identifies land where development implications exist due to the Obstacle Limitations Surface for certain airports, as designated by the relevant NSW environmental planning instrument (EPI). The Environmental Planning Instrument (EPI) contains provisions relating to airspace operations, and restricts certain development that penetrates the identified surface. These are "Additional Local Provisions" that can be found in Part 6 or Part 7 of the EPI.
