SUBJECT:  Sea-Tac Stakeholder Advisory Round Table (StART) Update

EXECUTIVE SUMMARY

The briefing  will  include  an  overview of StART's  creation,  its  organizational  structure,  the
formation of the Aviation Noise Working Group, the working group's efforts to date and plans
for 2019.

FORMATION OF StART

Cognizant of Sea-Tac Airport's continued growth and the community impacts associated with
that growth, the Port is committed to building open relationships with the community and local
jurisdictions that foster trust, accountability and collaboration. An important component of
that earnest effort was the creation in early 2018 of the Sea-Tac Stakeholder Advisory Round
Table (StART).

After conducting research on various engagement strategies employed at selected airports in
the summer of 2017, Lance Lyttle, the Airport's Managing Director, and External Relations staff
met with the administrative leadership from the six airport-area cities (SeaTac, Burien, Des
Moines, Normandy Park, Tukwila and Federal Way) to gauge their level of interest in a
stakeholder advisory roundtable.  The administrative leadership agreed on the need for a
roundtable and over a series of working meetings, reached an agreement on StART's formation,

purpose and structure. StART's inaugural meeting was on February 28, 2018.

PURPOSE OF StART

As established within StART's Operating Procedures:

StART provides Southwest King County cities, communities, airline representatives, the Federal
Aviation Administration (FAA) and the Port with the opportunity to:

Meeting Date: January 22, 2019

e   Support meaningful and collaborative public dialogue and engagement on airport-
related operations, planning and development;
Provide an opportunity for the communities to inform the airport-related decision
making of the Port of Seattle and other Southwest King County
jurisdictions/organizations; and
e   Raise public knowledge about the airport and impacted communities.

e   Focus on practical solutions to reduce the impact of the airport on neighboring
communities.

The intent is to provide a forum that fosters a spirit of good will, respect and openness while
encouraging candid discussion between the Port and residential and business community
members.

ORGANIZATIONAL STRUCTURE OF StART

StART is convened by the Airport's Managing Director, who in addition to serving as the chair,
serves as the sponsor directing staff to provide technical analysis and expertise to the group.
An independent, neutral facilitator provides assistance in the preparation, management and
summation of each StART meeting.

Each of the six airport-area cities appoints two community members to serve on StART along
with a non-elected city employee who is typically a city manager. Members are appointed for a
two year term. StART's effectivenessis driven by a willingness by all parties to fully discuss
matters of mutual concern and all members are asked to pledge their good faith best effort to
achieve those ends.

Representatives from Alaska Airlines, Delta Air Lines and Lynden Air Cargo participate as
members and the FAA provides agency expertise.

City representation on StARTis identical to the Highline Forum's city representation and StART
reports up to the Highline Forum. In this way, both StART's community representatives and the
Highline Forum's elected representatives are involved in airport issues and can provide a
coordinated approach among stakeholders.

StART meets six times a year with its next meeting occurring on February 27, 2019. Meetings
are typically held in Sea-Tac Airport's Conference Center, are noticed and open to the public.
Limited time is set aside at each meeting for the public to provide comments pertinent to the
topics listed on that day's meeting agenda.

AVIATION NOISE WORKING GROUP

After dedicating the first two StART meetings to increasing awareness around a number of
aviation-related topics, the members had an open conversation at their June meeting about

Meeting Date: January 22, 2019

where they would like to focus their energies going forward. The June conversation ended with
the decision to create a smaller working group, comprised of volunteer StART members and
representatives from Delta, Alaska, the FAA and the Port. Their assignment: prioritize and
explore a list of potential near-term actions to prevent and reduce aviation noise.

A noise/aviation consultant, with experience working with similar stakeholder groups, was
hired by the Port to provide technical analysis to the working group. The working group, since
its launch in August, has met five times.  Updates on the working group's progress are provided
at all StART meetings.

NEAR-TERM AVIATION NOISE ACTION AGENDA

At the working group's first meeting in August, the members approved exploring four near-
term efforts linked to preventing and reducing aviation noise:

Runway Use Plan Agreement
Late Night Noise Limitation Program
Glide Slope Analysis
Airfield Noise Assessment

The four near-term efforts were branded the Near-Term Aviation Noise Action Agenda. If and
when appropriate, the working group could consider adding other efforts to the agenda.

With the Runway Use Plan Agreement and the Late Night Noise Limitation Program, significant
progress has been made by the working group to date. A preliminary draft of the Runway Use
Agreement has been submitted to the FAA for review and the Late Night Noise Limitation
Program is currently in design. The working group is expected to recommend a path forward
for the Glide Slope Analysis in early 2019. Work on defining the Airfield Noise Assessment will
begin in early 2019.

(1) Runway Use Plan Agreement: The most consequential proposed change to the
agreement, which was implemented originally in 2010, is language clarifying
minimized use of the 3" Runway during the late night hours (12:00 AM to 5:00 AM).
FAA review and acceptance of the new agreementis required and an FAA-directed
environmental review might also be a requirement. Potential enactment: mid-2019

(2) Late Night Noise Limitation Program: The program is designed to reduce late night
(12:00 AM to 5:00 AM) noise by incentivizing air carriers to fly at less noise sensitive
hours or transition to quieter aircraft. The incentive is the addition of a new
category to the Port's already established Fly Quiet Program that assigns air carriers
a penalty score for any late night flights above a specified noise threshold. The
Program's various thresholds are still being calculated. Once complete, the Port will
begin publicizing the program with the air carriers.  Potential enactment: mid-2019

(3) Glide Slope Analysis: Approaches for raising Runway 34R'sglide slope from 2.75
degrees to 3.0 or 3.1 degrees are currently under evaluation. Raising the glide slope
on Runway 34R could provide a small noise reduction for aircraft arriving over
communities south of the airport. A defined approach and timeline will require FAA
approval. As a next step, options forraising the glideslopes on all runways higher
than 3 degrees will be evaluated. Potential enactment: TBD

(4) Airfield Noise Assessment: The assessmentis expected to investigate and determine
sources ofairfield noise troublesome to the community, including noise generated
by aircraft reverse thrust.  Potential enactment: TBD

StART IN 2019

StART will continue on with its bi-monthly meeting in 2019 serving as a forum for hearing the
concerns from the six neighboring airport communities and for identifying ways where all
parties can work together more cooperatively on possible solutions to those concerns.

The Aviation Noise Working Group will continue to meet on a monthly basis to advance the
Near-Term Aviation Noise Action Agenda.  Other efforts are expected to be identified by the
working group in 2019 and included as part of the agenda including a campaign to encourage
air carriers to retrofit A320 aircraft to reduce noise when descending.

At its December 19 meeting, StART also agreed to form a new working group focused on
federal policy. Specifically, the new working group would look at policies already passed as part
of the  FAA  Reauthorization  legislation  and  aviation-oriented  legislation  expected  to  be
championed by U.S. Representative Adam Smith in the next Congress.  The goal would be to
identify ways where StART can work collectively to ensure these enacted and proposed policies
and legislation are fully and successfully implemented.  The new working group is expected to
hold its first meeting early in 2019.
