George England, Program Leader, Aviation Project Management 
SUBJECT:  Doug Fox Site Improvements Authorization for Design and Construction (CIP 
#C800451) 
Amount of This Request: $1,028,000    Source of Funds: Airport Development Fund 
Est. State and Local Taxes: $58,000    Est. Construction Jobs Generated: 10
Total Project Cost: $1,028,000
ACTION REQUESTED:
Request Commission authorization for the Chief Executive Officer to complete the design and
proceed with construction for the Doug Fox Storm Drainage Improvements Project at Seattle-
Tacoma International Airport; and to use Port Construction Services crews for the construction 
work. The total project cost is $1,028,000. This request is time-sensitive and seeks a single
Commission authorization to perform the design and construct the drainage improvements before
the issuance of a request for proposals for a new operator of the parking lot during the second 
quarter of 2012. 
SYNOPSIS:
This memorandum requests Commission authorization to design and construct the Doug Fox
storm drainage improvements at an Airport automobile parking lot. The project is located at the 
Airport on Port property commonly known as the Doug Fox Lot. The property is located
immediately north of South 170th Street and east of the Airport Expressway (see attached Figure 
1). The lot provides parking spaces for Airport customers and is operated by a third party 
contractor. This project will support the Port's ability to maintain revenue generating capability
of the lot by constructing improvements to the existing storm drainage system. The work is
highly time-sensitive, and this single request for both design and construction will enable the
project to be completed at the end of the dry summer season so that third party operations can
consider the completed work in their vendor proposals to the Airport. This project is included in
the 2012 capital budget.

BACKGROUND: 
The Doug Fox facility is currently operated as a surface parking lot for Airport parking by a third
party contractor, ATZ Inc. Doug Fox is the brand name affiliated with the facility. The lot has
been utilized primarily for automobile parking since its development well over 20 years ago.
Many elements of the parking facility are deteriorating, including the pavement, the building
located at the south end of the facility, and most important, the stormwater collection system. 
The current site drainage system was installed in the 1970s. Over time this antiquated system has
increasingly failed to satisfactorily collect and convey stormwater off the lot to the Port's storm
drainage system. Poor drainage has caused a host of problems with standing water and
deterioration of the asphalt pavement throughout the lot. If not dealt with, this poor drainage will
negatively impact the revenue generating potential of the property. The proposed scope of work
(see attached Figure 2) includes design and construction of a new on-site drainage system,
improving the connection to the Port's off-site drainage system at S. 170th Street to accommodate
the increased peak flow rate generated from the new on-site system and replacing asphalt
pavement and re-striping where installation of the storm drains occur. 
The lease with the current lot operator expires on September 30, 2012. Port staff expects to
solicit requests for proposal for a new operator of the lot in the second quarter of 2012. It is
desired to have the proposed improvements completed prior to September 30, 2012, such that
responders to the request for proposal can factor the benefits of the lot improvements into their
proposals. In order to complete the work prior to the end of September, staff requests
authorization of both design and construction at this time.
Port Engineering will design the project, with engineering support if needed via service
directives under existing indefinite delivery, indefinite quantity (IDIQ) contracts. Construction
will be performed by Port Construction Services with support from small works contractors.
Port design and construction resources will be used because they have the capability and
availability to meet the completion date objective of this project. 
Port staff is currently evaluating additional improvements for the site relating to ingress/egress,
lighting, paving, the existing building and the revenue control system that are intended to
increase the revenue-generating potential of the property. Staff will return to the Commission at
a future date for authorization of these improvements if it is determined that they are necessary.
These future potential improvements would be completed as a different project after completion
of this work.
PROJECT JUSTIFICATION: 
With the current lease expiring soon, the Airport has the opportunity to make needed repairs to
the facility to maintain parking operations and associated revenues. Localized flooding due to
currently inadequate stormwater drainage equates to a poor customer experience. The Port will 
invest in stormwater drainage improvements to support the basic functions of the lot and remedy
the basic customer service needs by modifying the antiquated and failing stormwater system.

Project Statement: 
This project will install new stormwater drainage within the Doug Fox parking lot to improve the
customer experience and to minimize further deterioration of the pavement at the site. 
Project Objectives: 
The Port's objective is to maintain the financial return from this asset by constructing minimal
stormwater improvements. A better customer experience will result from replacing the existing
inadequate drainage system that causes localized ponding and the asphalt pavement to fail. An
additional project objective is to minimize potential adverse operational and financial impacts on
the lot operator during construction. This objective will be met by phasing the work and close
coordination with the current operator. 
PROJECT SCOPE OF WORK AND SCHEDULE: 
Scope of Work: 
Site drainage system improvements 
Drainage system improvements on S. 170th Street. 
Asphalt pavement replacement and re-striping in areas disturbed by drainage system
construction.

Source of Funds 
This project, CIP #C800451, is included in the 2012  2016 capital budget and plan of finance. The
funding source for this project will be the Airport Development Fund. 
Financial Analysis Summary:
CIP Category           Renewal/Replacement 
Project Type            Renewal/Replacement 
Risk adjusted Discount rate   8% 
Key risk factors           The first key risk associated with the improvements is the
possibility of construction delays. Such delays may cause
transition problems if construction is extended beyond October
1, 2012. A second risk is the possibility of contaminated soils
associated with construction. In addition, if operational impacts
during construction are not adequately managed, there may be
resulting impacts to customer service levels and revenues at the
facility. 
Project cost for analysis      $1 million 
Business Unit (BU)        Business Development 
Effect on business         The analysis assumes that if the fundamental improvements
performance           proposed in this request are not approved, the current revenue
stream at the parking facility would be jeopardized. Therefore,
with approval of this request, annual revenues ranging from $2
million to $3 million over the next 15 years are projected,
assuming continuity of current operations. 
IRR/NPV            NPV: approximately $21 million, based on continuity of current
revenue stream over the next 15 years. 
Payback: one year 
Lifecycle Cost and Savings: 
The project's lifecycle cost includes the initial capital cost of $1,028,000 plus future inspection
and maintenance costs estimated to be $3,000 per year (in year 2012 dollars). Maintenance cost
savings are anticipated from mitigating the existing stormwater ponding problems. 
ECONOMIC IMPACTS AND BUSINESS PLAN OBJECTIVES: 
Approval of this project will allow for continuity of operations at the Doug Fox parking facility
at acceptable operational standards to maintain current customer service levels. This project
allows the Airport to maximize its non-aeronautical operating income which is one the Airport's
Strategic Business Goals.

STRATEGIC OBJECTIVES: 
This project aligns with the Port's objective of maintaining and enhancing customer service
levels for the traveling public. In addition, a result of this project will be the ability of the Airport
to maintain a current non-aeronautical revenue stream. 
ENVIRONMENTAL SUSTAINABILITY AND COMMUNITY BENEFITS: 
This project will provide the opportunity to apply environmental sustainability principles
primarily through improvements to the storm drainage system. Other sustainability principles
and standards will be used where practical to minimize project lifecycle costs. Contaminated
soils, if discovered at the project site, will be removed as required by regulations.
TRIPLE BOTTOM LINE: 
The project supports economic development by investing in an upgraded parking lot to serve the
public's needs at the Airport. Environmental sustainability principles will be employed as
needed or when practical, such as removal and disposal of contaminated soil if discovered during
excavation, and recycling of asphalt removed for the pipe trench. Procedures set forth in the
Port's new Small Contractor and Supplier Program from the Office of Social Responsibility will
be used when applicable in the project contracting process. 
ALTERNATIVES CONSIDERED AND THEIR IMPLICATIONS: 
Alternative 1  Improve the site stormwater drainage system as proposed. This alternative will
lead to a better customer experience at the Doug Fox parking lot, will reduce further impacts to
the pavement at the site due to poor drainage and will preserve an important non-aeronautical
revenue stream. This is the recommended alternative. 
Alternative 2  Do nothing. Do not implement any improvements to the existing Doug Fox
parking lot. This alternative is not recommended because the lot's current deficiencies would
continue to exist, resulting in a poor customer experience and continued deterioration of the
pavement that will negatively impact the revenue generating ability of the property. This is not
the recommended alternative.
