SUBJECT:  Muckleshoot Indian Tribe and Port of Seattle; Fish and wildlife habitat rehabilitation
project, Terminal 105 public shoreline access site 

Est. Total Contract Cost:   No new funds requested 
Source of Funds:        Muckleshoot Indian Tribe 
ACTION REQUESTED: 
Request Commission authorization for the Chief Executive Officer to prepare and sign an interlocal
agreement with the Muckleshoot Indian Tribe, substantially as described in this memorandum, allowing
for construction of a fish and wildlife habitat rehabilitation project at the existing Terminal 105 public
shoreline access site. Port management and construction costs will be reimbursed by Muckleshoot
Indian Tribe, using restoration grant funds received by the Muckleshoot Indian Tribe. No new funding is
requested. 
SYNOPSIS: 
The Muckleshoot Indian Tribe, a federally recognized sovereign Indian Tribe (Tribe) and the Port, share
important interests in Elliott Bay and the Duwamish Waterway. The Muckleshoot Indian Tribe has
treaty reserved rights and resources, including usual and accustomed fishing areas, in Elliott Bay, the
East and West waterways, and the Duwamish Waterway. The Port owns marine terminal facilities,
shoreline, and aquatic area within the Muckleshoot Indian Tribe treaty reserved protected rights and
resources area. Stewardship of these shared resource areas is critically important to the welfare of the
Tribe and its members as well as essential to the Port's strategic facility, business, and environmental
objectives. 
The Tribe and the Port have worked cooperatively in recent years to sustain treaty fishing rights and
efficient, productive Port maritime operations. The Tribe and the Port propose to construct fish and
wildlife habitat improvements at Terminal 105, implementing habitat restoration beneficial to their
mutual interests. 
SCOPE OF WORK: 
The Muckleshoot Indian Tribe has received grant funding for fish and wildlife improvements in the
Duwamish Waterway and has proposed working with the Port to construct habitat improvements at Portowned
Terminal 105 property. Staff proposes that we work with the Tribe to implement this habitat
restoration. The Tribe will provide project funding, including paying for Port staff time and Terminal

105 site work conducted by Port Construction Services. The Port will provide the land, and will manage
the construction work, being reimbursed by the Tribe for costs, other than cost of land.
The Tribe and the Port have identified three habitat restoration actions for the Terminal 105 site
located on the west bank-line of the Duwamish Waterway, approximately River Mile 0.6. Restoration
actions would affect approximately 1.3 acres, shallow sub-tidal and inter-tidal  aquatic area, and
approximately 225 linear feet of shoreline area. Project activities intended to enhance and improve
estuarine aquatic resource values in former marine industrial aquatic area and shoreline include the
following: 
(1) Piling and debris removal: The primary activity includes extraction/removal of derelict creosote
piling (up to approximately 250 derelict former shipway and marina piling) and associated
intertidal/shallow subtidal debris. 
(2) Clean sand cover: Void spaces and irregular surfaces remaining due to piling and debris removal
will be receive clean sand cap material, matching adjacent substrate areas. 
(3) Bank-line stabilization: Following piling and debris removal, approximately 250 linear feet of
existing eroding upper bank-line area will be stabilized with anchored large-woody-debris and
native riparian vegetation. 
City, state, and federal authorizations for the proposed Terminal 105 habitat restoration project are
expected in December 2015. Rehabilitation project construction would begin in January 2016,
concluding in June 2016. 
Up to $300,000 in grant-funds from the Muckleshoot Indian Tribe will be used for project actions.
Terminal 105 aquatic area and shoreline rehabilitation actions will combine to remove physical
impediments to migratory salmon and resident fish and wildlife, while improving estuarine natural
resource functions and quality. In addition, the 1.3 acre site will be cleared of obstacles and debris,
aiding Muckleshoot Indian Tribe fishing/harvest access in the Duwamish Waterway. Project design and
construction techniques are intended to avoid and minimize future maintenance needs 
Please note that the existing Terminal 105 public shoreline access site has received previous grantfunded
fish and wildlife habitat improvements, provided by a combined U.S. Fish and Wildlife Service,
Environmental Protection Agency, U.S. Army Corps of Engineers initiative. In 1996-1998, the port
constructed an approximately 0.7 acre, 950 feet long, inter-tidal channel, buffered with approximately
1.2 acres of native riparian vegetation. Additionally, in the past five years the site has benefited from
approximately 1200-1500 hours of citizen volunteer riparian habitat maintenance work. 
FINANCIAL IMPLICATIONS: 
Source of Funds: 
No new funding is requested. Funding provided by the Muckleshoot Indian Tribe will provide port staff
resources necessary for project design, city, state, and federal permit review, and project management.
In addition, all construction costs will be reimbursed using grant funds. 
Costs: 
All port staff, project management, and construction costs will be reimbursed with funds from the
Muckleshoot Indian Tribe. Future maintenance costs are anticipated to be minimal. Please note that the

previous fish and wildlife habitat restoration area has not required maintenance associated costs in the
past 17 years.
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
(1) Accept Terminal 105 fish and wildlife habitat restoration opportunity with the
Muckleshoot Indian Tribe 
This project will provide approximately 1.3 acres progress towards the Century Agenda
restoration goal of creating, restoring or enhancing 40 acres of habitat in the Green Duwamish
watershed. 
This provides an opportunity to work on a cooperative project benefiting fishing access and
habitat with the Muckleshoot Indian Tribe. 
This may lead to future opportunities to use other agreements for mutual benefit, expanding
scope for potential settlement agreements. 
This opportunity underscores importance of "government-to-government" interactions. 
No cost to the Port except the cost of land. 
This is the recommended alternative. 
(2) Decline opportunity 
Lost opportunity to for cooperative government-to-government action. 
Port will retain potential for future restoration work 
Diminishes ability to expand scope of future settlement agreements, including potential
economic, cultural, and environmental actions. 
Lost opportunity for highly visible Duwamish Waterway project contributing to Century
Agenda restoration goal. 
This alternative is not recommended.
