Amount of this request:                                                     $0 
Total estimated project cost:     $25,921,000, with $307,500 going to each tribe 
ACTION REQUESTED 
Request Commission authorization to transmit funds that are necessary to fulfill agreements
with the Muckleshoot Indian Tribe and Suquamish Tribe for construction of the Terminal 117
Habitat Restoration and Duwamish Shoreline Access Project. These funds are included in the
previously authorized funding for the project. 
PROJECT INFORMATION 
Execution of the construction contract for the Terminal 117 Habitat Restoration and Duwamish
Shoreline Access Project was authorized by Commission on April 28, 2020. As a necessary
component of securing federal permits for the project, agreements were negotiated with the
Muckleshoot Indian Tribe and Suquamish Tribe that require minor design modifications,
installation of interpretive signage, special landscaping requirements, and a contribution of
$307,500 to each tribe's fisheries mitigation fund. The agreements insure that the temporary
loss of access to treaty-reserved fishing areas at the project area during construction are offset.
Tribal consultation is undertaken for all in-water construction projects at the Port. These are
standard agreements for Port projects and aligned with past practice involving significant inwater
work. 
JUSTIFICATION 
The Terminal 117 Habitat Restoration and Duwamish Shoreline Access Project, over ten years in
the making, supports the Port's triple-bottom line sustainability objectives: it achieves 
significant social, environmental, and financial goals. Construction of the project was
authorized by Commission on April 28. As a component of federal permitting actions, tribal
agreements were negotiated to offset temporary loss of treaty-reserved fishing area. These
agreements, originally negotiated in 2018, now require a one-time contribution of $307,500 to

the Muckleshoot Indian Tribe's and Suquamish Tribe's fisheries mitigation funds prior to start of
construction. The pre-construction, non-monetary components of the agreements have already
been fulfilled and the two tribes have removed their objections to the project permits. The
agreements require Commission authorization to transmit the required funds in order for
construction to proceed.  The cost of these agreements are included as part of design and
permitting costs in the Cost Breakdown for the full T117 project (approved on 4/28/20).
