PORT OF SEATTLE 
MEMORANDUM 
COMMISSION AGENDA                      Item No.         6b 
Date of Meeting      November 23, 2010 
DATE:      November 12, 2010 
TO:         Tay Yoshitani, Chief Executive Officer 
FROM:     Christine Wolf, Seaport Transportation Program Planner 
Mike Campagnaro, Manager, Container Leasing 
SUBJECT:   Proposed Utility Easement with Seattle City Light at Terminal 46. 
ACTION REQUESTED: 
Request authorization for the Chief Executive Officer to execute a proposed Easement Utility Agreement,
substantially as described in this memorandum, with Seattle City Light (SCL) for an area covering
approximately 400 square feet, for the installation of switching equipment supporting the electrical
infrastructure at Terminal 46 (T-46). 
SYNOPSIS: 
Approval of this request allows the execution of a proposed perpetual easement with SCL to install and
maintain electrical switchgear and related underground power infrastructure on T-46. The proposed new 
infrastructure will improve the reliability of the power supply to T-46's north substation and provide for
existing and future terminal needs, such as shore power. In the future, the equipment is expected to
potentially support AWV construction power needs and service to other SCL customers. The proposed
easement location is to the north of T-46's King Street staff parking lot entrance. Locating the switch at
this site is necessary to make room for construction of the Alaskan Way Viaduct Replacement Project,
and to provide a safe, permanent location that minimizes the risk for power disruptions to T-46's north
substation. 
BACKGROUND: 
In preparation for construction of the replacement of the Alaskan Way Viaduct, the Washington State
Department of Transportation (WSDOT), in coordination with SCL, is relocating electrical power lines
and related infrastructure in the vicinity of the Holgate to King Project and the South Tunnel Portal. SCL
is taking the opportunity to upgrade and improve the reliability of its power infrastructure in the vicinity
of T-46 as part of this effort. 
Currently, T-46's power comes from an overhead feeder line along Alaskan Way. The existing overhead
line is being replaced by an underground line. Moving the feeder cables underground requires new
switchgear. It is proposed to be located on Port of Seattle property, immediately to the north of the King
County Regulator station, at the eastern edge of T-46's staff parking lot (See Exhibit A). This location
minimizes the risk of construction disruptions, vehicle collisions, conflicts with pedestrians/bicycles, and
potential relocation as a result of SR99 central waterfront reconstruction. The new switchgear will also
allow power to be fed to the terminal from either of two different directions, further improving the

reliability of the terminal's power supply. The switchgear will provide for existing, as well as future T-46
needs such as shore power. It is sized to allow for potential Design/Build construction power and service
to other customers, although the additional capacity will not be used until the proposed easement has been
finalized. 
Staff has worked with both WSDOT and SCL to minimize the risk of construction-related power
disruptions to the terminal, and to avoid any impact of this easement on the operation of the terminal. The
proposed location of the switch is outside the operational area of the terminal and is expected to eliminate
one of 221 parking spaces. The proposed easement will provide a permanent location for new conduit,
vault, and switchgear for the terminal's north substation, out of the way of the Holgate to King
Street/South Portal and central waterfront construction. This is a significant improvement over earlier
construction plans, which had provided for a temporary relocation of power infrastructure before moving
it to its permanent location. 
Under normal circumstances, staff would have fully negotiated the easement with SCL before asking for
Commission approval. However, the current proposal was developed in the last four weeks to
accommodate the construction needs of the Design/Build contractors for the bored tunnel, and future 
needs for the central waterfront portion of the Alaskan Way Viaduct Project. Placing and energizing this
equipment by April 2011 is necessary for the Alaskan Way Viaduct Replacement Project to stay on the 
critical path. Since it also provides significant benefit to the Port and its tenant, staff is requesting that the
Commission approve the easement substantially as described below, so that construction can begin while
final details are being negotiated. Staff would come back to Commission for approval of any changes if
the negotiations result in an easement agreement that is substantially different from what is described in
this document. The Easement Agreement will include the following provisions: 
The permanent easement would be approximately 20 ft X 20 ft, (See Exhibit B) and be subject to the
following conditions: 
Non-exclusive easement for power distribution facilities consisting of underground vaults
and conduits, a pad-mounted switch cabinet, and fencing. 
Access to the easement for operation and maintenance would be from the east (i.e.
Alaskan Way right of way), and not from Port property, without additional approval of the
Port. 
Above-ground facilities would be restricted to the easterly 15 feet of the easement area. 
The westerly 5 feet of the easement area will be restricted to access for construction and/or
crew access for maintenance and replacement of electrical distribution facilities. This area
will be repaved for parking use by the Port and its tenant. 
Above-ground facilities and fencing will be located so as to impact no more than one (1) 
existing parking stall. 
The Port will receive compensation based on the fair market value of the permanent
easement rights. 
This proposed easement would result in a reduction in the leased area for T-46 tenant Total
Terminals International LLC (TTI). The Port and TTI are in agreement that the easement
area will be removed from their leasehold and a corresponding reduction made in their

rent. This will require an amendment to the TTI lease which will be brought before the
Commission at a later date.
