An airport master plan is a comprehensive study of an airport that describes its short, medium, and long-term sustainable development goals, alternatives, and plans. Master plans are required by the Federal Aviation Administration (FAA) to establish the regulatory framework for our future development, both airside and landside. Find the current Master Plan here.
