    Port Of Seattle and City of SeaTac approve Interlocal Agreement as partnership for mutual success

The proposed agreement, intended to replace the expiring February 2018 ILA, aims to improve efficiency, reduce costs, and avoid litigation through a mutually beneficial, comprehensive package of terms.
