Date of Meeting  December 13, 2011

DATE:   December 2, 2011 
TO:     Tay Yoshitani, Chief Executive Officer
FROM:   Dan Burke, Regional Transportation, Public Affairs
Eric Hanson, Seaport Planning Manager
SUBJECT: Authorization to enter into the Argo Yard Truck Roadway Memorandum of
Understanding (MOU) and approval of Port funding for the Project.
Total Project Cost: $7,800,000
Port of Seattle Cost: $2,200,000
Source of Port Funds: Tax Levy
Jobs Created: 93 FTE construction jobs
ACTION REQUESTED:
Request the Port Commission to authorize 1) the Chief Executive Office to execute the Argo
Yard Truck Roadway MOU with the Freight Mobility Strategic Investment Board (FMSIB), the
City of Seattle (City), the Union Pacific (UP) Railroad and Prologis L.P. (Prologis); 2) approval
of Port of Seattle funds of $2,200,000 for the project; and 3) approval of the project, including
initial steps of right-of-way acquisition and completion of design.
SYNOPSIS:
Many stakeholders involved in harbor drayage have for many years envisioned a shortcut from
Harbor Island to the UP Argo Yard. Given the expected completion of the East Marginal Way
Grade Separation project, this vision has gained traction as a significant component for creating a
virtually seamless expressway between marine terminals and the near-dock, intermodal yard at
Argo.
Currently, trucks transiting from Harbor Island to Argo must merge through three lanes of traffic
in a distance of only 1,000 feet. Further, trucks are delayed while waiting for the green arrow
signal at the intersection of East Marginal Way and Diagonal Avenue. Finally, there is a
frequent occurrence of port trucks awaiting this left turn signal to queue-up past the left turn

holding pocket which causes not just increased congestion but also unsafe driving conditions for
general purpose traffic southbound on East Marginal Way.
Creation of the proposed Argo Yard Truck Roadway will reduce round-trip, dray-times for
harbor truckers while improving safety for general purpose traffic. The project will accomplish
these goals by creating an automated gate system (AGS) at the Argo Yard which will speed truck
processing and a drayage route shortcut which bypasses the need to use congested portions of
East Marginal Way.
Funding for this project will be provided by the Port, the Freight Mobility Strategic Investment
Board, and Union Pacific.
THE PROJECT:
The project has three elements. Element I consists of a private, southbound only, roadway from
the north end of the Argo Yard to Colorado Avenue. The roadway will be for the sole use of
port drayage truckers and Prologis truckers. By privatizing use of the road, the project is able to
reduce the width of the road and therefore reduce the amount of property acquisition. Both UP
and Prologis are providing property for Element I through the conveyance of easements. The
roadway will be 16 feet wide and provide security fencing adjacent to the UP and emergency
vehicle access along the Prologis side of the road.
Element II of the project consists of roadway improvements along Colorado Avenue and near the
intersection of Colorado avenue and Diagonal Avenue. The intent of these improvements is to
utilize striping, new curb cuts and other relatively simple means to better manage truck traffic in
the area. Creating a specific design for these improvements will involve participation from all
parties to the MOU.
Element III of the project will automate the truck gate at the UP Argo Yard. The UP is the sole
project lead for design, permitting and construction of the AGS.
Port staff will only request execution of the MOU from the Chief Executive Officer if the
significant content of this draft remains unaltered. If there are material changes, Port staff will
return to the Commission for additional authorization.
PORT ROLES AND RESPONSIBILITIES:
The Port will:
a)  Act as project lead for design, permitting and construction of Elements I and II.
b)  Manage transference of FMSIB funds for all elements of the project.
c)  Contribute $2,200,000 to Elements I and II.
d)  Retain responsibility of maintenance for the roadway in Element I.
e)  Retain operational liability for use of the roadway in Element I.

Risk factors              As the lead agency for this project, the Port may be
considered responsible for potential project cost overruns.
Cost for maintaining the roadway may be more than
anticipated.
Port will retain operational liability for use of the roadway.
Partners may opt out of agreement during right-of-way or
design phase, resulting in lost up-front planning and design
costs for the Port.

Effect on business         Spending on this project will be expensed as incurred, as a non-
performance          operating expense.
Costs to maintain the roadway are currently estimated to average
approximately $5,000 per year.

ENVIRONMENTAL SUSTAINABILITY AND COMMUNITY BENEFITS:
The project will eliminate drayage truck idling at the intersection of East Marginal Way and
Diagonal Avenue thereby reducing greenhouse gas and diesel particulate emissions. The project
will increase traffic safety for both harbor truckers and general purpose traffic.
The Argo Yard Truck Roadway Project will provide a shorter dray and improved safety for port
related trucks. The project is supported by the Washington Trucking Association and the Freight
Mobility Strategic Investment Board. General purpose traffic mobility and safety will be
improved as trucks will detour from East Marginal Way to the new truck roadway. Though there
are no formal studies to verify benefits of the entire project, it is believed that the combination of 
a shortened and speedier dray route along with the enhanced processing speed of the AGS can
provide truckers the opportunity to make one additional dray-trip during the course of a routine
work shift.
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS:
In 2005, the Port studied alternatives to the current freight route from the Port terminals to the
UP Argo Yard gate. Four alternatives identified different routes which avoided the weave and
busy intersection at Diagonal Avenue. However, all the alternatives, with the exception of the
