INFORMATIONAL MEMORANDUM
TO: Mayor Haggerton
Transportation Committee
FROM: Bob Giberson, Public Works Director and
Jack Pace, Community Development Director
BY: Moira Carr Bradshaw, Senior Planner
DATE: June 6, 2012
SUBJECT: Duwamish Transportation Management Association (DTMA)
ISSUE
Briefing Alternatives to Drive Alone Commuting in the Duwamish Manufacturing Industrial
Center
BACKGROUND
The DTMA is a non profit group dedicated to improving transportation services in, to
and through the Duwamish business community. Because of the many challenges of
transportation within the Duwamish Industrial Centers, a group of local businesses
several years ago joined together to form the DTMA. The DTMA is a partner to the
Manufacturing and Industrial Council (MIC), which formed in 1998 with a handful of
volunteers concerned about the future of Seattle's industrial business community. Today
the group includes many members some big, some small all sharing a commitment
to retain and support the family wage job base of this area and in the region.
DISCUSSION Dave Gering, Executive Director of the MIC will provide an overview of
the results of the Street Smart report and answer any questions about his organization
and the report. In collaboration with King County Metro and the Port of Seattle, and with
Congestion Mitigation and Air Quality grand fWnds, the DTMA produced the Street
Smart report. The goal of the study is to reduce single occupant vehicle use in the
Manufacturing and Industrial Centers of Tukwila and Seattle. Attached are the
recommendations within Tukwila. The recommendations within the report were used to
support a Tukwila 2012 King Countywide Non motorized application that is currently on
the contingency list.

Executive Summary
The Duwamish industrial area presents major challenges to those who seek to travel by
bicycle or foot, and the barriers often make it hard for people to reach bus stops and other
public transit facilities. Some major new improvements for non motorized transportation
are occurring through construction for high profile projects, including the Alaskan Way
Viaduct, Spokane Street, and the South Park Bridge. But those projects will conclude
with no solutions in place for extensive areas throughout the Duwamish where bicycle
riding and walking are limited by unpaved roads, no sidewalks, "stranded" bicycle paths,
lousy drainage, and poor or no street lighting.
Street Sniart: Alternatives to Drive Alone Conininting in the Duwamish sets forth
recommendations for overcoming these barriers through further implementation of local
government master plans for bicycling and walking and other measures. The project
emphasizes projects that would improve connections between the Seattle and North
Tukwila Manufacturing and Industrial Centers and the local communities that comprise
those centers SODO, Georgetown, South Park, and North Tukwila.
Recommendations were produced by a multi -modal advisory group that reviewed public
plans and policies with input from more than 100 community organizations and
businesses. On an area -wide basis, the multi -modal effort prioritized future capital
improvements to:
improve cycling safety through safer, more complete trail routes;
increase the use of "hybrid" commutes that combine cycling with transit, and
enhance pedestrian access to existing transit services through sidewalk, bus stop,
crosswalk, and lighting improvements.
Consensus was not reached on all issues. The Cascade Bicycle Club seeks separated
bicycle facilities such as buffered bicycle lanes or separated cycle tracks for many
planned bike routes in the industrial community, including sections of major truck streets
such as East Marginal Way and Airport Way. The Duwamish Transportation
Management Association feels it may be premature to determine that such improvements
are warranted.
However, most recommendations were agreed to by all the parties, including a
recommendation to determine if Airport Way could become a north -to -south bike route
through the Duwamish that could be pursued through collaborative efforts by Seattle,
Tukwila, and King County International Airport.
Such an effort on Airport Way could be tied to other north -south improvements on East
Marginal Way and West Marginal Way to improve connectivity with the Green River
Trail and other facilities in the south Duwamish planning area.
Completion of the South Park Bridge in 2013 will also present new opportunities to
pursue related sign, lighting, transit, bike, pedestrian, and road surface improvements.
16
The stadium district in north SODO also presents a large number of problem areas where
significant cycling and pedestrian improvements should be pursued as government
agencies complete the Alaskan Way Viaduct replacement project.
One such effort, already under way, is improving bicycle access and safety along the
surface route of Alaskan Way adjacent to the major marine cargo terminal at Terminal 46
west of the sports stadiums. That project provides a good template for other collaborative
efforts. The safety improvements should be extended to the south along Alaskan Way to
connect with Spokane Street and the bridge to West Seattle.
The Duwamish will remain a challenging area for those who seek alternatives to drive
alone commuting, but new online programs and networks provide new tools that make it
possible for every employee and employer to find alternatives. Some of those programs
are available through the online version of this report available at
www.duwamishtma.org.
The top recommendations of this report are summarized below, referenced to the fold -out
map at the conclusion of the Executive Summary.
SODO:
1. Rehab the Alaskan Way S multi -use trail as a separated north -to -south route in to and
out of the Duwamish M &I Center.
2. Complete separated multi -use SODO Trail south from S Forest St to S Spokane St.
3. Provide sharrows between S Spokane St and S Royal Brougham Way along Airport
Way S to increase driver awareness of cyclists.
4. Connect the planned multi -use path on the lower level of the S Spokane St project to
SODO Trail and Airport Way S.
5. Incorporate bicycle and pedestrian facilities into proposed S Lander St grade
separation project.
6. Complete planned extension of Mountains -to -Sound Trail at S Royal Brougham Way
and
4th Ave S.
7. Create access to SODO from Beacon Hill for connecting with the Chief Sealth Trail
(proposed) continuation.
Georgetown:
8. Signs beginning at S Hudson St should direct southbound cyclists to alternative routes
leading to the S River St entrance to the 1 st Ave S Bridge so that they may avoid the S
Michigan St intersection.
17
9. Take advantage of the bike lanes on E Marginal Way S from S Albro St to S Ellis St to
South Park Bridge (once bridge construction is complete), to bypass residential and
commercial pockets of Georgetown as part of a commute route.
10. Continue planned sharrows and signs along E Marginal Way S from Corson Ave S to
the S River St crossing to the west for the 1" Ave S Bridge, or east to 6' Ave S heading
to the north and the east -west route on S Lucile St.
11. Paint sharrows along S Lucile St, the east -west link between l Ave S and Airport
Way S.
12. Enforce sidewalk and parking regulations on the east side of 4th Ave S, north of the
railyard bridge to keep parked cars out of the pedestrian path and to reduce sidewalk
maintenance and repair costs.
13. Construct a raised platform or repair the drainage systems at the northbound transit
stop at 4th Ave S and S Industrial Way to combat the flooding that users regularly
experience.
14. Provide signs and kiosks along S Lucile St connecting pedestrians from transit routes
on 1 st Ave S and 4th Ave S to the Design District and Commercial area along Airport
Way S.
South Park:
15. Direct travelers from the Duwamish River Trail or the 1 st Ave S Bridge to the new
South Park Bridge by placing an informational kiosk at S Holden St and directing them to
S Kenyon St, Dallas Ave S, and finally 14th Avenue S.
16. Place a kiosk on 14 Avenue S. near the SR 599 cloverleaf to show cyclists how to
reach the South Park Bridge and retail area along 14th Avenue S via W Marginal Way S.
17. Install a kiosk at the South Park Bridge directing westbound bridge travelers to bike
routes and trails on the west side of the Duwamish.�
18. Improve access to transit by providing a bus platform at 2nd Ave S and S Holden St
in the eastbound direction.
19. Provide better lighting for transit users and pedestrians along 14 Avenue S between
S Cloverdale St and SR99 intersection and W Marginal Way S and S Holden St.
20. Use new signage and improved maintenance to encourage use of the stairs near Sea
Mar Community Health Center.
18
North Tukwila:
21. Widen the existing pathway on the west side of Airport Way Sfnorth side of S Boeing
Access Road to facilitate a safer connection between Airport Way S and E Marginal Way
S, a 12' multi -use trail from EMW to Airport Way S to S Norfolk St.
22. Remove inactive rail line to install a separated multi -use trail on the west side of E
Marginal Way S, connecting to the Green River Trail.
23. Continue Green River Trail north connecting to South Park.
24. As recommended in the Walk and Roll plan, the proposed trail connection between S
115' St along the western edge of the future Duwamish Riverbend Hill Park up to S
Boeing Access Road and Airport Way S would provide a much- needed trail bypass route
to the complex intersection of S Boeing Access Road and E Marginal Way S.
25. Rechannelize S Norfolk St to provide 6' bicycle lanes on both sides of roadway
(existing: four travel lanes, low traffic volumes).
26. Widen existing pathway on the north side of S Boeing Access Road to provide a
multi -use trail connection between E Marginal Way S and Airport Way S.
27. Restripe S 112th St to provide 5' bicycle lanes on both sides, and install wayfinding
signage directing users to Green River Trail.
28. Provide signage directing users to Green River Trail from Tukwila International
Blvd., deal with access management issues (between S Boeing Access Road. and S 112th
St); parking is encroaching on sidewalk. In the long term, Green River Trail should be
extended on the east side of the waterway, along Tukwila International Blvd. and E
Marginal Way S.

Non motorized Commute Network through the Duwamish M &I Center
Duwamish Transportation Management Association
,,p o'I
V. North Tukwila
When the North Tukwila Manufacturing and Industrial Center was designated in 1992 as part of
the region's land use and transportation plan, the plan called for the area to set a light -rail station
along the Boeing Access Road as part of the new light -rail system that was then being planned.
However, the proposed station was indefinitely postponed because of cost benefit issues, and the
nearest light -rail station was built instead at the Tukwila transit center on International
Boulevard, about 3 miles south of the Boeing Access Road.
Companies in the North Tukwila area still want the station. Other issues cited by community
members include:
Poor east -west connectivity in the road system;
Underutilization of the Green River Trail;
Large blocks that make pedestrian crossings uncomfortable; and
Many transit routes require two or more transfers.
Like Seattle's industrial areas to the north, North Tukwila has a disconnected sidewalk network
and a high volume of truck traffic on its streets. Unlike Seattle, Tukwila possesses a major
regional bike route, the Green River Trail, running right through the M I Center, that can be
used as part of a bike or pedestrian separated commute.
The Green River Trail could tie in the Airport Way route for a new regional, north -south bike
connection between north Seattle and south King County. But the effort would probably require
collaboration between the cities of Seattle and Tukwila in partnership perhaps with King County
International Airport.
A similar opportunity exists to better continue the Green River Trail into South Park along West
Marginal Way to connect with 14th Avenue South leading to the South Park retail area. From
there, cyclists could travel west to the 1 st Avenue South Bridge over the Duwamish River, or
continue north on the Duwamish Trail along West Marginal Way to West Seattle. Or, they could
ride from the retail area over the new South Park Bridge and on to Georgetown.
The multi -modal group reviewing North Tukwila also recommended:
Promoting hybrid bike bus rail commutes to increase east -west connectivity, taking
advantage of Tukwila being served by both light and heavy rail;
Increasing signage and lighting on the Green River Trail to encourage its use as a commute
option, not just a recreational facility; and
Installing mid -block crossings on selected roadway segments to reduce block size to a more
approachable scale for pedestrians and transit users.

„p3 1'I
The two most recent plans that have been developed relating to non motorized transportation in
North Tukwila include the City of Tukwila's Walk and Roll Plan (adopted in 2009) and the
Tukwila Bicycle Friendly Routes and Sidewalk Segments Design Report.
The Walk and Roll Plan recommends a network of bicycle facilities throughout the city. The
Design Report provides detailed design recommendations and cost estimates for specific
bicycling projects along the city's recommended network.
Note about S 102nd Street. A privately owned facility (by The Boeing Company), S 102nd St is
identified in both the Walk and Roll Plan and the Design Report as a recommended bicycle
friendly route. The Design Report also recommends improvements along S 102nd St; however,
the report also states that S 102nd St is private from East Marginal Way to S River St, and that
any work would require agreements with The Boeing Company.
The Tukwila Walk and Roll Plan identifies S 102nd St as a "bicycle friendly route” and indicates
a planned trail between the S 102nd St Bridge and W Marginal Place, however, there is no
discussion of proposed bicycle facilities along S 102nd St and no discussion of the ownership of
this right of way. While S 102nd St presents a key opportunity for bicycle connectivity, issues
involving access and improvements to this facility would need to be worked out with the private
property owner.
Barriers
The multi -modal group agreed on the following barriers to safe pedestrian and bicycle travel in
North Tukwila.
Location Barriers/Issuen

RECOMMENDATIONS
The multi -modal group endorsed the recommendations set forth in both the Walk and Roll Plan
and the Tukwila Bicycle Friendly Routes and Sidewalk Segments Design Report, subject to
additional review as noted in the recommendations. The Duwamish TMA would su --est a caveat
that the cities of Tukwila and Seattle should collaborate in planning for their mutual connections
between Airport Way, East Marginal Way, and West Marginal Way, hopefully in partnership
with King County International Airport (KCIA) and other property owners including The Boeing
Company. Boeing employees make up a large share of cyclists and pedestrians in the local
vicinity of the potential improvements. They along with the broader community should be
engaged. The following recommendations provide timely starting points for a collaborative
review.
Issue Recommendation

Access Road to Seattle west side of Airport Way /north side of
city limits) BAR to facilitate a safer connection
between Airport Way and East
#21 on Map Marginal Way S 12 -foot multi -use

E Marginal Way Recommendation I (near- term): Provide
#22 on Map dedicated bicycle facilities between S
128th St and the Seattle city limit. Bicycle
facilities could include cycle tracks or
buffered bicycle lanes with painted bike
lanes at key conflict points.
Opportunities for installing bicycle lanes
include:
BAR to S 90th St: Remove 1
southbound lane (to provide cycle
tracks or buffered bicycle lanes);
S 90th to S 81st St—if ADT is too
high to remove 1 south- or northbound
lane, evaluate turn lane necessity,
S 81 st St north: remove 1 southbound
lane.
Recommendation 2 (long- term):
Remove inactive rail line to install a
separated multi -use trail on the west side
of EMW, connecting to the Green River
Trail.
