COMMISSION AGENDA               Item No.       5e 
Date of Meeting      May 12, 2009 

DATE:    April 28, 2009 
TO:      Tay Yoshitani, Chief Executive Officer 
FROM:    Eric Hanson, Manager, Seaport Planning
Christine Wolf, Regional Transportation Program Planner, Seaport 
SUBJECT:  Execution of easements with the City of Seattle Department of Transportation for a
Dynamic Message Sign at Terminal 5. 
ACTION REQUESTED: 
Authorization for the Chief Executive Officer to approve and execute easements with the City of Seattle
Department of Transportation, substantially in the form shown in Exhibit A, for the installation and
maintenance of certain equipment necessary for a Dynamic Message Sign providing current traffic
information to trucks leaving Terminal 5. 
SYNOPSIS
Approval of this request allows the execution of easements with the City of Seattle Department of
Transportation for the installation, maintenance, and operation of a Dynamic Message Sign at the
entrance of Terminal 5. (See Exhibits B and C.) The sign will be used to inform truck drivers leaving the
terminal of traffic conditions and bridge openings, allowing them to make informed routing decisions, 
avoid congestion, and reduce idling. 
BACKGROUND
On April 21, 2009, the Commission passed Resolution 3615, authorizing the Chief Executive Officer to
enter into an agreement with the City of Seattle to make a direct contribution of $500,000 the City's
Duwamish Intelligent Transportation Systems (ITS) project. The Port's contribution helps fund several
Dynamic Message Signs in the Duwamish, including a Dynamic Message Sign (requested by Port of
Seattle staff) facing the out gate of Terminal 5. The sign will be placed in the planting strip at the
touch-down of the access ramp, facing the Terminal gate. The sign will be located in the lease area, but 
outside the operational area of the Terminal. The Terminal operator supports placement of the sign
because it helps facilitate the movement of trucks. There is no additional budget impact.
