Airport and that these are the modes with the highest emissions impacts. It was also noted that
although limousines have a high emissions impact, the percentage of travelers using them to travel
to the Airport was only about 1 percent in 2015 and 2016. The fact that the data provided did not
differentiate between visitors, residents, and employees as distinct markets was pointed out. 
Commissioners commented on the effect of traffic congestion as a factor in reducing the Airport's
catchment size within the region, the need to consider traffic congestion impacts regionally and on
local communities, the benefits of addressing transportation behavior through agreement
structures, the effects of light-rail-related parking on neighborhoods, and the need to promote use
of transit to reduce congestion and environmental impacts of getting to and from the Airport. 
Participants were given an opportunity to respond to the following questions: 
(1) How does your agency/business support the region's air travelers, visitors, and
employees in a sustainable and equitable manner? And in the future? What gaps do you
see in the service your agency will provide? 
(2)   What opportunities are available with technology innovations or other changes? What
may cause disruptions, volatility, uncertainty, complexity, or ambiguity? What risks come
with accommodating 66 million passengers? 
(3)   How might we work together to fill the gaps we foresee? Who must we enlist to assist? 
Participants commented on transportation network company (e.g. Uber and Lyft)  growth,
opportunities to alleviate Airport drive congestion with opening of south access to the Airport via
SR-509, considerations for tolling SR-509, options to leverage Metro King County Transit as a tool
to reduce congestion from employee traffic, and the limitations on local regulation to effectively
deliver regional transportation solutions. 
The failure to incorporate light rail closer to the Airport terminal was noted as a missed opportunity
both for past transit planning and the current ST-3 proposal. Commissioners noted the hope for
better collaborative planning as the Sustainable Airport Master Plan matures.

The meeting adjourned at 11:53 a.m.
