Environmental Assessment


In May 2022, Cape Cod Gateway Airport completed the development of a 20-year master plan to ensure that the facility can continue to safely and efficiently meet the aviation needs of the National Airspace System and the surrounding community. The preparation of an airport master plan is required by the Federal Aviation Administration (FAA) in order to plan for the future and highlight airport projects in need of future federal funding, including rehabilitation of existing infrastructure. The goal of the Airport Master Plan is to provide the framework needed to guide future airport development that will cost-effectively satisfy aviation demand, while considering potential environmental and socioeconomic issues.

The Master Plan is the first part of the planning process; environmental review is the second part of the process and finally implementation and development of the projects proposed.

Master Plan Timeline Graphic

Any expansion coming as result of the Master Plan will need to undergo an environmental review process which looks at both on airport and off airport impacts, this study will need to be conducted before any expansion will take place and can only begin after the master plan study is complete.

The Environmental Assessment will be conducted to meet federal and state environmental review requirements of National Environmental Policy Act (NEPA) and Massachusetts Environmental Policy Act (MEPA).
