SUBJECT:  Pier 34 Mooring Dolphins Project (CIP #C800090) 
Amount of This Request:        $1,500,000   Source of Funds:       General Fund 
Est. Total Project Cost:          $1,800,000 
ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to advertise for construction
bids, execute construction contracts, and fund the installation of four replacement mooring
dolphins at Pier 34. The total amount of this request is $1,500,000, for a total estimated project
cost of $1,800,000. 
SYNOPSIS 
The project consists of the replacement of four existing failing timber mooring dolphins with
four new steel dolphin structures located at the northwest margin of Terminal 30, north of the
Terminal 30 container cargo apron, in the northeast portion of the East Waterway. This project
would ensure future productive use of an  existing  aged and failing moorage facility. 
Rehabilitation of the Pier 34 moorage structure would accommodate up to two 400-foot long 
barges, generating continuing revenue for the Seaport. 
The design concept is to provide replacement steel dolphins with sufficient strength to securely
moor vessels during a  20-year expected life. In addition, the project would remove
approximately 90 failing creosote timber piles, as a coincident environmental benefit. 
Marine industrial moorage for barges and other commercial vessels is fundamental to a healthy
port and harbor. The supply of industrial moorage in our harbor has declined, while demand for
such moorage has grown.  This project would restore moorage capability and capacity that has
diminished due to age and deterioration. 
BACKGROUND 
This request is part of the Seaport's Asset Stewardship Program and the "Industrial Moorage
Initiative" that was presented as a Policy and Staff Briefing in public session on June 3, 2008. 

Template revised May 30, 2013.

By proceeding with this project, the Port protects current industrial moorage business, ensures
future revenue from industrial moorage, and supports maritime jobs, all of which align with the
Port's Century Agenda goals. 
The present project will also serve to provide alternative moorage service displaced from other
Port  facilities following the implementation of two federal security programs initiated in
February 2009, the Marine Transportation Security Act (MTSA), and Transportation Worker
Identification Credential (TWIC) requirements.  Activation of cruise operations at Terminal 91 
in April 2009 further restricted the Port's supply of industrial moorage. 
PROJECT JUSTIFICATION AND DETAILS 
Project Objectives 
Repair and rehabilitate essential marine industrial moorage infrastructure to restore harbor
moorage capacity. 
Remove the existing failing timber dolphins at Pier 34 and replace with durable, long life-
cycle steel mooring dolphins. 
Provide moorage to a diverse spectrum of users as detailed in strategic objectives above. 
Provide additional moorage to alleviate the current shortage caused by the relocation of
Cruise operations to T-91, 
Provide an alternative to the current practice of rafting barges in the lower Duwamish
Waterway. 
Provide moorage for vessels subject to Maritime Transportation Security Act (MTSA)
without the added cost burden of security fees for berths with landside requirements for a
TSA Facility Security Plan. 
Generate additional revenues to the Seaport. 
Scope of Work 
Construction 
Advertise, award, and execute a Major Works contract for the replacement of four mooring
dolphins at Pier 34 to include: 
Removal of four existing creosote timber pile cluster dolphins (approximately 90 piles). 
Removal of deteriorated timber decking. 
Installation of four steel dolphins. 
Schedule 
For the rehabilitated Pier 34 moorage facility to be available in spring 2015, all in-water
work for this project will need to be substantially completed prior to February 15, 2015. The
design and permitting work covered under this authorization is expected to be completed by
August 2014. All construction work is expected to be completed and the rehabilitated
facility ready for service by April 2015.

STRATEGIES AND OBJECTIVES 
This work, if authorized, advances Seaport's Asset Stewardship Program - to restore and
preserve Port owned facilities in our harbor. 
Demand has been expressed by industry for the following uses: 
o  Seasonal barge moorage in winter, when barge service to ice-restricted regions of Alaska
stops; 
o  Support for local shipyards by berthing vessels awaiting or upon completion of dry-dock
repairs; 
o  Daily moorage, as a preferred substitute to mooring at the Duwamish Head Buoys; and 
o  Alternative seasonal moorage during Treaty tribe fishing periods, reducing barge
movement and moorage congestion in the Lower Duwamish Waterway and Elliott Bay.

ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1: Replace the current timber dolphins at Pier 34 to accommodate current barge
berth moorage demand and restore capacity. The 2008 Industrial Moorage Initiative identified
the Pier 34 moorage site as the most effective site available for improving industrial moorage.
Pier 34 has served this function in the past, is the most straightforward to permit, and can meet
the current schedule for the 2015 completion. This is the recommended alternative. 
Alternative 2: Select a different site. Rehabilitate or install new moorage structures at an
alternative site.  For example, the 2008 Industrial Moorage Initiative also identified T-5 North 
and T-10 as potential sites, but potential mitigation and permitting complications make them
problematic and  unlikely to be usable in the needed timeframe.  Alternative 2 is not
recommended. 
Alternative 3: Do nothing. With growing demand and the continued displacement of barge
moorage at T91, the Port does not have adequate barge moorage for current and future tenants.
Alternative 3 is not recommended.
