Framework
Guiding Principles                 Framework provides clear guidance
about how to evaluate strategies
and tactics
Goals
Illustrates extent to which an
approach achieves desired outcomes
Strategies                      Applies to facilities, operations and
regional strategies
Tactics
4

Guiding Principles
Consider overall environmental effects and reduce impacts
where possible
Improve customer experience by reducing roadway congestion
Support customer choice for a range of transportation options
to and from the airport
Support living wage jobs and equal business opportunities
Generate revenue to support region's needs for a sustainable
airport, including leveraging existing infrastructure
Principles applied to GTAP strategies and consistent with study sessions
5

Goals
Reduce 2007 scope 3 GHG emissions* 50% by 2030 (to 79k)
2017 Scope 3 GHG emissions*: 190,000 tonnes/year
Max 15 minute travel time  clock tower to curb or parking
Port data will be leveraged to track travel time
Reduce private vehicle pickup/drop off to 30%
Current mode share: 41%
Achieve social equity goals (support living wages and equal
business opportunities)
Ensure a first-class ground transportation operation for
customers through financial sustainability

Initiatives to Leverage Existing Infrastructure
Continuous Process Improvement exercise focused on airport
roadway congestion  shifted TNCs to Arrivals Drive in a.m. peak
Evaluate immediate GT recommendations (e.g. garage
utilization, alternate GT entrance)
Express Bus/Eastside Baggage study
Rematch program for TNCs
Widen Arrivals Approach project
SR 518 Corridor study
Taxi RFP draft
Ongoing initiatives will significantly reduce congestion and some will reduce carbon

Ground Transportation Access Plan
(GTAP)

Study Objectives
Increase access to high occupancy modes
such as transit
Advance transportation modes and programs
to foster social equity and customer choice
Consider the financial/revenue impacts of
potential strategies.

GTAP objectives advance all three aspects of sustainability
10

Study Approach
Conduct Research:
Identify benchmarks and existing conditions,
review regional transportation plans
Stakeholder Outreach
Data Analysis
Generate comprehensive list of
candidate strategies (64 total)
Level 1: Evaluate and rank candidate strategies
for GTAP goals. Identify top 10.
Level 2: Identify equity tradeoffs among top
strategies and quantify key metrics
Recommend strategies and
tactics for Port to explore
GTAP used systematic approach with robust outreach                    11

Top 10 GTAP Strategies and Tactics
Near-term Port initiatives:
Express Bus/Eastside Baggage Service (feasibility study)
Form an airport-wide Transportation Management Association (TMA)
Partner with regional agencies to incentivize mode shift:
Information sharing and promoting transit
Public-private partnerships for First/Last Mile Coverage
Increase/preserve King County Metro RapidRide and Sound Transit bus service
Offer ticket for free transit ride/ride-free area
Provide incentives (e.g., coupons) for ride-share and transit use
Further analyze:
Revenue structures for autonomous vehicles (AVs)
Airport access fees
Restructuring Port employee parking
Each of the 10 strategies needs additional research and/or key partnerships
