TO: Stephen P. Metruck, Executive Director
FROM: Keri Stephens, Director Aviation Facilities and Capital Programs
Eileen Francisco, Director Aviation Project Management Group
SUBJECT: Landside Pavement Program (C801042)
Amount of this request:
$4,630,000
Total requested project cost:
$9,320,000
ACTION REQUESTED
Request Commission authorization for the Executive Director to take all steps necessary to
complete the Landside Pavement Program project at Seattle-Tacoma International Airport (SEA).
The total amount requested for authorization is $4,630,000 for a total authorization amount of
$9,320,000.
EXECUTIVE SUMMARY
The Landside Pavement Program will implement a series of pavement rehabilitation projects that
supports the Port’s Century Agenda strategy to position the Puget Sound region as a premier
international logistics hub, by maintaining one of the most basic of the facilities infrastructure
assets, pavement. This authorization request supports the completion of the first phase of the
program that will address pavement that has been prioritized by condition. The project will also
take advantage of a pavement preservation grant from the Puget Sound Regional Council (PSRC)
for the northbound Northern Airport Expressway that will be delivered as part of the 1947
Watermain Improvements (C801224) project.
JUSTIFICATION
This project supports the following Century Agenda strategic goals and objectives:
1) Advance this region as a leading tourism destination and business gateway by meeting
the region’s air transportation needs at the Airport for the next 25 years.
2) Use the Port’s influence as an institution to promote women and minority business
enterprise (WMBE) growth through Resolution 3737 – Diversity in Contracting WMBE
aspirational goals, small business growth, and workforce development by increasing the
proportion of funds spent by the Port with qualified firms on construction, consulting,
goods, and services.

Meeting Date: November 12, 2024
Template revised June 27, 2019 (Diversity in Contracting).
Replacing distressed pavement and supporting infrastructure on the landside supports the long-
term strategy of the Port’s Century Agenda objective to “advance this region as a leading tourism
destination and business gateway by meeting the region’s air transportation needs at the Airport
for the next 25 years.” The Landside Pavement Program maintains the integrity of SEA landside
pavements and enables efficient airport operations.
Diversity in Contracting
Project staff along with the Diversity in Contracting Department have set a women and minority
business enterprise (WMBE) aspirational goal of 12% for this construction contract.
DETAILS
The SEA Landside pavement and roadway system consists of 2.5 million square feet of pavement.
The Landside Pavement Program will rehabilitate portions of these SEA landside pavements over
time. The goal of the Landside Pavement Program is to assess pavement conditions (such as
cracks, potholes, rutting and other distresses) by periodically performing a pavement condition
index (PCI) survey, assigning a remaining service life, and providing a 10-year pavement
maintenance and rehabilitation project plan to maintain a minimum pavement condition at the
lowest total cost of ownership. The intent is to deliver the improvements in the most economical
way, as either a stand-alone project or combined with other projects in the Aviation capital
program. Work will include pavement rehabilitation (overlay or replacement depending upon
condition), removal of abandoned utilities within the work areas, enhancements to related
surface water drainage facilities, and improvements to meet required code or standards for other
ancillary facilities (e.g., signage, lighting, sidewalks, bicycle lanes).
Aviation Facilities and Infrastructure developed a formal Landside Pavement Program in
collaboration with the Aviation Project Management Group. In 2021, staff completed an initial
inspection of the landside pavements to establish a PCI rating. These PCI ratings are used to
identify and prioritize pavement renewal and replacement to maximize their service life at the
lowest total cost of ownership. The goal is to maintain all pavements at a PCI of 70 or higher.
In 2022 the Port of Seattle was awarded a PSRC pavement preservation grant to address the
rehabilitation of a portion of the northbound Northern Airport Expressway.
Scope of Work
This initial phase of the Landside Pavement Program includes the reconstruction of the south
parking entrance between the ticket dispensers and the helix entrances, and the rehabilitation
of landside pavements in the worst condition. These include the following:
(1) Southbound Northern Airport Expressway (from S 170
th
St to the Departures/Arrivals
decision point)
(2) Air Cargo Rd (from the North Entrance of the Service Tunnel to S 170
th
St)

(3) S 190th St (from 28th Ave S to the parking lot entrance, and by the fuel farm within the
parking lot)
(4) Northbound Northern Airport Expressway (Arrivals curbside/S 182
nd
St entrance to
northbound lanes)
(5) Airmail Rd
Staff reviewed projects in the Aviation capital program to identify opportunities for more
economical scope delivery, reducing multiple operational impacts and avoiding costly rework.
Two projects were identified that would support the delivery of this initial phase of the Landside
Pavement Program. The Widen Arrivals Roadways (C800866) project will complete the
pavement rehabilitation scope on Air Cargo Rd and southbound Northern Airport Expressway.
The 1947 Watermain Improvements project is planned to deliver the pavement rehabilitation
scope for the northbound Northern Airport Expressway and that work is included in this
authorization request.
Schedule
The following schedule is limited to the work to be completed as part of the Landside Pavement
Program and does not reflect the work to be performed as part of the Widen Arrivals Roadways
or 1947 Watermain Improvements projects.

ALTERNATIVES AND IMPLICATIONS CONSIDERED
Alternative 1 – Do nothing.
Cost Implications: $1,700,000
Pros:
(1) Capital investment not required.
Cons:
(1) Does not address failing pavements and would likely lead to more costly “total
reconstruction” projects in the future or major disruptions to airport operations.
(2) Fails to take advantage of a PSRC grant for the rehabilitation of a portion of the
northbound Northern Airport Expressway.
(3) The project costs to date would need to be expensed.

This is not the recommended alternative.
Alternative 2 – Address all distressed pavement outlined in the Landside Pavement Program.
Cost Implications: $20,000,000
Pros:
(1) Addresses all pavements with PCI rating of less than 70 and the south parking entrance.
(2) Takes advantage of PSRC grant funding for the rehabilitation of a portion of the
northbound Northern Airport Expressway.
(3) Leverages other on-going construction projects to implement pavement rehabilitation
scope reducing overall program costs.
Cons:
(1) Greater overall capital investment in the short-term. The project budget was originally
reduced due to the financial impacts from COVID-19.
This is not the recommended alternative.
Alternative 3 – Address distressed pavements within current budget.
Cost Implications: $9,320,000
Pros:
(1) Lower overall capital investment in the short-term.
(2) Addresses pavements in the worst condition and the south parking entrance.
(3) Leverages other on-going construction projects to implement pavement rehabilitation
scope reducing overall program costs.
Cons:
(1) Does not address all pavements requiring rehabilitation. This alternative would require
a future request for the next programmed phase of the Landside Pavement Program in
the near term.
This is the recommended alternative.
