Dear Ms. Kennedy: 
Continuing public review of the SODO arena proposal presents an unprecedented
opportunity to better inform local and regional decision-makers about longstanding
SODO transportation needs and concerns. The Duwamish Transportation Management
Association proposes to help inform that process through a community-based outreach
program enabling input by those who work, own companies and land in SODO, as well
as those throughout the region and state who depend on SODO as a hub for import and
export services. 
We hope the Port of Seattle will consider a sponsorship for this program. The Port was a
founding cosponsor of the TMA a decade ago and served as a key partner in several
subsequent TMA projects. 
The final scope and work plan for the TMA outreach program will be developed in
collaboration with a wide range of SODO stakeholders. The initial concept is to conduct 
a community-wide survey of those who work and do business in SODO combined with
outreach to those in the larger region who depend on SODO as a major statewide
strategic resource. These outreach efforts would be combined with public forums with
elected leaders and government managers, and would result in publication of a report
with key findings and recommendations for local, regional and state decision-makers. 
The TMA proposes initially that program outcomes should help: 
augment and support existing and future efforts to identify SODO's regional and
local freight needs and assets; 
identify arena mitigation measures that benefit the broader community; 
identify transportation and public transit improvements, opportunities and needs
that will be created by completion of major highway improvements in SODO,
including completion of the deep bore tunnel. 
The TMA would prepare the report through an inclusive process similar to a variety of
past TMA efforts that were based on input from freight companies, bicycle and
pedestrian groups, retailers, manufacturers, major employers, stadium operators and

government transportation agencies including the Seattle Freight MobilityAdvisory
Board, SDOT, King County Metro, WSDOT and the Port of Seattle. A past example of
this approach is available online at www.duwamishtma.org under the "Street Smart"
report, published in 2011. That report includes a previous community-based effort from
2009 that examined safety issues along 1st Avenue South between the stadium area and
Spokane Street. 
The TMA is well-suited to the present task because it is a transportation service and
planning organization that takes no political positions except to advocate for improved 
transportation services in SODO. The TMA can accept contributions through the 501
(c)(3) Seattle Industry Foundation. 
Thanks for forwarding this concept to the Seattle Port Commission and port staff. Please
call if we can answer any questions. 
Sincerely, 

Dave Gering, Executive Director 
Duwamish Transportation Management Association
