ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to: (1) proceed with design of
the S. 160th St. Ground Transportation Lot Project for an estimated $667,000; (2) execute utility
agreements with Puget Sound Energy (PSE), Comcast, and CenturyLink to underground utilities;
(3) grant and transfer a utility easement, if necessary, to PSE, Comcast, and CenturyLink on Port
property along the south side of S. 160th St. for the underground utilities; (4) reimburse PSE,
Comcast, and CenturyLink in an amount not to exceed $540,000 for the utility undergrounding
work; and (5) transfer the utility undergrounding scope of work and $973,000 of authorized
budget from the Off-Site Roadway Improvements (ORI) Project to the S. 160th St. Ground
Transportation Lot Project. 
SYNOPSIS 
The Port's S. 160th Ground Transportation Lot serves as a holding area for limousines, buses,
and taxis that serve Airport passengers. An existing building on the lot provides office space and
amenities for taxi drivers; however, it is in sub-standard condition and requires renovation.
Other proposed lot infrastructure improvements include a storm drainage system, lot re-striping,
and curb, gutter, and sidewalk along S. 160th St.
The project also includes undergrounding of existing overhead utility lines along the south side
of S. 160th St. Originally included in the ORI project as part of the Rental Car Facility (RCF) 
Program, undergrounding of the overhead utilities was deferred per agreement between the Port
and City of SeaTac. The undergrounding scope of work must be transferred from the ORI project
and be completed as part of the S. 160th St. Ground Transportation Lot improvements. The
existing overhead utility lines are owned by PSE, Comcast, and Century Link. These companies

will perform the undergrounding design and construction and be reimbursed for their actual costs
by the Port in an amount not to exceed $540,000.
Depending on the alignment of the utility undergrounding determined during the design phase,
the Port may need to grant an easement on Port property along the south side of S. 160th St. The
requested authorization is for the design of the building renovation and lot infrastructure,
entering into agreements with utility companies to perform the design, construction and seek
reimbursement from the Port, grant and transfer, if needed, an easement to the utility companies
for the underground utilities, and transfer of the previously authorized scope and funds from the 
ORI project to the S. 160th St. Ground Transportation Lot project. Staff will return to
Commission for authorization to construct the building and lot improvements in the future. Total
project cost, including the utility undergrounding, is estimated to be $3,559,000. 
This project was included in the 2014  2018 capital budget and plan of finance.
BACKGROUND 
Lot Improvements 
The Port owns and operates the S. 160th St. Ground Transportation Lot located immediately
south of the RCF between Host Road and International Blvd. (see Attachment A). Existing
facilities were constructed in 1991, and vehicle access to and from S. 160th St. was recently
upgraded as part of the ORI project. 
The proposed project will provide a renovated building and other site improvements to support
an existing ground transportation facility. The taxi administration building has endured intense
use during the past 20 years and the interior has reached the end of its useful life. The building is
leased to Yellow Cab as part of their concession agreement. As part of the agreement, the Port is
responsible for building maintenance. Yellow Cab has approximately 700 drivers that use the
building on a regular basis. The renovation provides improvements to the building interior and
resolves habitability problems that can no longer be addressed through maintenance. In addition,
the lot's existing drainage system is not up to standard and does not adequately capture and
convey stormwater runoff. The project will connect the stormwater improvements to the off-site
storage water quality system located under the RCF to prevent erosion and protect Port of Seattle
property. 
Utility Undergrounding 
The ORI project completed the roadway improvements on State Route 518, International Blvd.,
S. 160th St, and Host Road as part of the RCF program. The Port and the City of SeaTac have an
Interlocal Agreement (2005 ILA) that addresses a number of issues associated with land use and
development on Airport property within the City of SeaTac. During the design of the ORI
project, the Port's original position was that the utilities in the area were located on Port of
Seattle property and therefore subject to the 2005 ILA rather than City of SeaTac Municipal
Code; however, after discussion with the City, it was determined that the utilities were located
within city right-of-way and subject to SeaTac Municipal Code. The timing of this discovery
precluded the undergrounding of utilities as part of the ORI project. In order not to delay the

scheduled opening of the RCF, the Port and City agreed that the Port would commit to 
undergrounding the utilities when performing future work in this area (see Attachment B). Staff
has determined the S. 160th St. Ground Transportation Lot project is the appropriate project to
incorporate completion of undergrounding existing overhead utilities and is requesting the
transfer of the scope of work and $973,000 of previously authorized customer facility charge 
funds for this purpose. 
Under an agreement with the Port, PSE will design and construct the undergrounding of the
existing overhead power lines. PSE will relocate electrical service as well as any Comcast and
Century Link services co-located with the power lines. The Port will reimburse these utilities for
their work to convert their communications lines to underground.  Some or all of the alignment
and trench for the utility undergrounding may need to occur on Port property along the south side
of S. 160th St.  Therefore, the Port may need to grant PSE, Comcast, and CenturyLink a
permanent easement to construct and maintain their respective utility lines. 

PROJECT JUSTIFICATION AND DETAILS 
The existing building suffers from overuse of restroom and kitchen facilities resulting in broken
plumbing fixtures, out of service showers, water leaks, water damage, broken tile, and stained
ceilings.  In addition, stormwater runoff on the lot is not adequately captured by a drainage
system. Rainwater often flows directly off the lot causing erosion damage. An expanded
drainage network is required to collect stormwater that flows across the lot and route it to an
existing pipeline and water quality treatment system at the RCF on the north side of S. 160th St. 
Existing aboveground utility lines along S. 160th St. should be undergrounded to meet the
provisions of the City of SeaTac Municipal Code.
Project Objectives 
Objectives of the proposed upgrades are to: 
Provide a renovated building with amenities for drivers 
Provide other site and infrastructure improvements 
Provide an upgraded ground transportation asset with a low total cost of ownership 
Underground utility lines along S. 160th St. 
Scope of Work 
Renovate existing drivers' building interior 
Complete the installation of curbs, gutters, and landscaping along S. 160th St. 
Install site storm drainage system with a connection to the RCF system 
Re-striping the existing lot to create more parking space and more efficient use 
Undergrounding of existing utility lines along S. 160th St. fronting Port property

TRIPLE BOTTOM LINE 
Economic Development 
The project supports economic development by investing in an upgraded ground transportation
lot to serve the public's needs at the Airport. Environmental sustainability principles will be
employed consistent with Port policy. In addition, procedures set forth in the Port's Small
Contractors and Suppliers Program will be used when applicable in the project contracting
process in coordination with the Office of Social Responsibility. 
Environmental Responsibility 
This project will provide the opportunity to apply environmental sustainability principles
associated with the new improvements, including: 
Upgrading the site drainage system to better manage stormwater 
Undergrounding utility lines to improve reliability and visual appearance. 
Utilizing energy efficient light fixtures and water efficient plumbing fixtures in the
building 
Community Benefits 
This project provides infrastructure upgrades and replacement to an Airport asset that provides a
significant service and benefits to passengers. The project also fulfills agreements with the City
of SeaTac to provide underground utilities along S. 160th Street. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
Alternative 1  Do nothing. Under this alternative, the existing ground transportation (GT) lot
facilities will continue to deteriorate. The habitability of the building and the functionality of the
storm drainage system will continue to be sub-standard.  Existing overhead utilities along
S. 160th St. will not be undergrounded. This alternative is not recommended. 
Alternative 2  Invest in the GT lot facility upgrades, but at a reduced scope of work from those
proposed here.  For example, the amount of building renovations could be reduced or an
upgraded storm drainage system could be deleted from the project. As with Alternative 1, the
habitability of the building and the functionality of the storm drainage system will continue to be
sub-standard, although existing overhead utilities along S. 160th St. would be undergrounded.
This alternative is not recommended. 
Alternative 3  Invest in the GT lot facility upgrades and underground existing overhead utilities
along S. 160th St. as proposed.  This will result in a renovated building with improved
habitability and lower maintenance and repair cost. The improved storm drainage system will
collect surface runoff from the lot with conveyance to the Rental Car Facility drainage system.
This is the recommended alternative.
