Interlocal Agreement Between the City of Des Moines and the Port Of Seattle for South 216th Street Improvements Fronting Port Of Seattle and WSDOT Property Referred to as Des Moines Creek West

This 2018 interlocal agreement between the City of Des Moines and the Port of Seattle outlines a cost-sharing arrangement for street improvements along South 216th Street, adjacent to the Des Moines Creek West (DMC-W) property near Sea-Tac Airport. The Port agreed to pay $1.5 million toward road upgrades accommodating pedestrians, cyclists, transit, and freight, with that payment credited against any future transportation impact fees tied to DMC-W development. The agreement also sets the stage for long-term ground leasing and commercial development of the approximately 20-acre DMC-W site to generate jobs and revenue for both parties.
