In recent times, some concrete structures have been mushrooming along Paro international airport stretch. While some have already constructed two-storey houses, others are told that their lands fall under no construction zone.
Those residing near airport premises have to seek construction clearance from Bhutan Civil Aviation Authority (BCAA). Approvals are given as per the flight funnel map that considers the safety and security of the airport and aircraft.
The colour-coded zoning maps show flight paths and standards of developmental activities such as heights of buildings and structures to ensure the safety of aircraft operations.
