Yn ogystal â darparu mynediad angenrheidiol i'r parc busnes, mae'r dyluniad wedi cynnwys gwaith amddiffyn amgylcheddol i helpu i warchod pentrefi Llan-maes a Threbefered rhag llifogydd.
In addition to providing the necessary access to the airside business park, the design has incorporated environmental defence works to help protect the villages of Llanmaes and Boverton from flooding.
