ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to advertise for bids, award, and
execute a major works construction contract to construct the Airport's South 160th Street Ground
Transportation  Lot  project  site improvements, for  an estimated amount  of $455,000  and  a total
authorization of $2,095,000. 
SYNOPSIS 
The Port's South 160th Ground Transportation (GT) Lot currently serves as a holding facility for the
Port's contracted taxi provider serving the main terminal of the Airport. This authorization request will
complete required environmental permit conditions related to storm drainage improvements at this lot 
that were part of the nearby Rental Car Facility (RCF) project.
BACKGROUND 
The Commission previously approved $1,640,000 to support project design ($667,000) and the Puget
Sound Energy utilities undergrounding work ($973,000) along South 160th Street. Improvements being
contemplated at the time of design authorization included a substantial interior renovation of the GT Lot 
taxi driver layover structure, as well as storm water drainage control site improvements and the utilities
undergrounding. The Port's Aviation Landside group is currently reassessing their landside operations
strategy at this time, to include how the layover structure will be used by current and future operators.
The Aviation Project Management Group, with the support of Aviation Operations, is moving forward
with permit-mandated storm water, sidewalk, and utilities undergrounding improvements at this time.

Lot Improvements (cost to construct: $455,000) 
The Port-owned GT Lot is located immediately south of the RCF between Host Road and International
Boulevard. This facility is currently leased to Yellow Cab as part of their five-year, $18 million
concession agreement. The existing facilities were constructed in 1991 and vehicle access to S. 160th St.
from the lot was upgraded as part of the Off-Site Roadway Improvements (ORI) project. The current 
project would provide limited site improvements to address outstanding environmental and construction
permit commitments from the RCF and ORI projects. 
The existing drainage system in the parking lot does not adequately capture and convey storm water
runoff. This project will improve collection of storm water on the GT Lot site, and then convey the
collected water to the storm water treatment system located at the RCF. This improvement would
complete the RCF's storm water permit requirements. As earlier authorized by the Commission, the
project would also complete the sidewalk and landscaping adjacent to S. 160th St. from where it 
currently terminates to the eastern Port property boundary. The estimated total construction cost for
these site improvements is $455,000. 
When implemented, the Sustainable Airport Master Plan (SAMP) will not impact the S.160th St. Lot for
approximately 10-15 years. The SAMP identifies several potential uses for the site: as the location of a
multi-story parking structure to support the continuation of current ground transportation operations, to
expand rental car storage capacity for the Rental Car Facility, or as a potential location of a maintenance
base for a potential automated people mover system. Regardless of future SAMP impacts, the Port must
meet its obligations on environmental and City of SeaTac permitting requirements. 

PROJECT JUSTIFICATION AND DETAILS 
The storm water runoff on the lot is neither adequately controlled nor captured, by the existing drainage
system. Rainwater often flows directly off the lot causing erosion damage to adjacent properties. A
modified drainage network is required as a previous permit condition to collect storm water that flows
across the lot and route it to an existing water quality treatment system at the RCF on the north side of S.
160th St. 
Permit conditions remaining from the ORI portion of the RCF project require completing the sidewalk
and landscaping along S.160th St. to the eastern edge of the Port property. 

Project Objectives 
Objectives of the proposed upgrades are to: 
Satisfy outstanding permit commitments 
Provide utility, storm water and pedestrian infrastructure improvements

Budget Status and Source of Funds 
The S. 160th St. Ground Transportation project, CIP #C101107, is included in the 2015  2019 capital
budget and plan of finance. The budget has been modified for scope reductions and scope additions. The
funding source for the 160th lot improvements will be the Airport Development Fund.  The funding
source for the $973,000 budget transfer from the RCF program (C100266) to accomplish the utilities
undergrounding is the Customer Facility Charge (CFC). The $973,000 can be broken down into capital 
assets that will owned by the Port post project ($286,000), and those that will be owned by others
($687,000). Any elements that will remain in the public right-of-way, such as curbs, sidewalks, and
public utilities are classified as public expense.

Project Type              Life Cycle Extension and Asset Protection 
Risk adjusted discount rate     N/A 
Key risk factors             Unforeseen site conditions could increase design and
construction costs and delay project schedule. 
Project cost for analysis        $1,408,000 (excluding utilities undergrounding) 
Business Unit (BU)          Ground Transportation 
Effect on business performance  NOI after depreciation will decrease. 
IRR/NPV             N/A, this is a renewal and replacement project that
increases the life of existing Port of Seattle assets that are
necessary to maintain revenue generation linked to taxi
services. 
CPE Impact             None 
The Port earns approximately $3.6 million annually from the taxi contract. This facility supports the
ongoing generation of these revenues. 
Lifecycle Cost and Savings 
The Maintenance Department anticipates the operating and maintenance costs of the upgraded storm
water system will be similar to the existing system, since the lot size remains the same. The new
improvements will reduce the need for repair activity associated with erosion on the site. 
STRATEGIES AND OBJECTIVES 
Meet or exceed agency requirements for storm water leaving Port-owned or operated facilities. 
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 in the project contracting process in coordination with the Office of
Social Responsibility. 
Environmental Responsibility 
This project will provide the opportunity to integrate environmental performance standards associated
with project improvements, including: 
Upgrading the site water drainage system to manage storm water; and 
Improving pedestrian facilities, safety, and connections.

Community Benefits 
This project provides infrastructure upgrades to an Airport asset that supports a beneficial passenger 
service. The project also fulfills agreements with the City of SeaTac to provide underground utilities
along S. 160th Street and complete the sidewalk network. The project manager has coordinated with the
Office of Social Responsibility to maximize the opportunities available to small businesses, including
those owned by minorities and women, in accordance with Port Resolution #3618. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
The $973,000 cost of the PSE undergrounding of overhead utilities on S. 160th St. transferred from
the RCF project to this CIP has been excluded from the cost estimates for the following
alternatives. The alternatives are also independent of design costs, and reflect solely the cost to
construct the projects. 
Alternative 1)  Maintain the status quo. (cost: $0) 
No changes to the existing facility would occur. Public expense dollars would not be allocated to the S.
160th St. aerial utilities undergrounding. 
Pros: 
The facility would remain open. 
Cons: 
The existing ground transportation (GT) lot structures will continue to deteriorate. 
Storm water will continue to impact adjacent properties and will not meet the flow control
requirements of issued water quality permits. 
Failure to adhere to City of SeaTac storm water requirements could incur a corrective action
notice and monetary fines. 
Alternative 2)  Reduced GT Lot improvement option (cost: $455,000). Recommended. 
Expense dollars would remain allocated to the utilities undergrounding, allowing that effort to move
forward. Capital spending for construction would be limited to the storm water control and conveyance
improvements required by the RCF's storm water permits, sidewalk and landscape completion, and
striping. 
Pros: 
Limited GT Lot upgrades would occur at reduced cost, but with a corresponding reduction in the 
scope of work. 
Completes RCF storm water conveyance and control permit commitments. 
Meets the commitment to the City that existing overhead utilities along S. 160th St. be
undergrounded. 
Reduces capital costs from $1.87 million for the previous full build option, to $455,000 for the
limited scope option.

Keeps Port from investing further in a building expected to be demolished within 10 to 15 years
as part of SAMP implementation. 
Cons: 
The men's restroom would remain as is: unimproved and quite worn down, and costly to clean
and maintain. 
The women's restroom, a lightly used facility, would not be upgraded. 
The day room area, used by over 700 drivers a day, and taxi dispatch office would remain
unimproved and quite worn down, but serviceable. 
The heating, ventilation and air conditioning (HVAC) system and roof would remain; both are
past their useful lifespans, and require additional maintenance expense to keep operational. 
As with Alternative 1, the general habitability of the building will continue to deteriorate. 
Building repair costs would continue to climb over time, but could be shifted to the taxi
contractor in future taxi operator contracts. 

Alternative 3)  Invest in complete rehabilitation of GT Lot facility (cost: $1.87 million) 
Expense dollars would be allocated to the utilities undergrounding, allowing that effort to move forward. 
The facility would be completely remodeled with a focus on durability and energy efficiency. Storm
water improvements would be installed. 
Pros: 
Existing overhead utilities along S. 160th St. would be undergrounded. 
Controls and conveys storm water properly to an existing Port storm water detention pond that
has been sized to accept this flow. 
The GT Lot building interior, roof, HVAC, electrical and plumbing systems will be updated to
meet current code requirements, and will reduce repair and janitorial requirements. 
New interior floors and finishes making extensive use of ceramic tile would be more durable and 
will require less maintenance. 
The improved storm drainage system will collect surface runoff from the lot with conveyance to
the Rental Car Facility drainage system. 
Cons: 
This alternative uses $1.87 million of capital funds; $1.41 million would be spent renovating the
existing structure and $455,000 would be directed towards constructing site improvements.
