I'm not sure exactly where, but the land across 07/25 (beyond the perimeter fence) from the existing business park is zoned for commercial use. There's also a parcel to the east of the end of 17/35 that is zoned for industrial.
Neither fits within what we conventionally think of as the airport boundary, but I know there is some land around the airport that is owned by the airport and rented out to farmers.
By far the biggest stroke was the transfer of the existing business park land from Cork Airport to the DAA in the accounts. It took an asset that was generating about 6 million a year in rental income (the airport only owned a minority stake) off the Cork books making it look much more loss making than it is.
