INFORMATIONAL MEMORANDUM
TO: Transportation and Infrastructure Services Committee
FROM: Pete Mayer, Deputy City Administrator/ Interim Public Works Director
BY: Catrien de Boer, Public Works Analyst
CC: Mayor McLeod
DATE: January 24, 2025
SUBJECT: Arterial Streets Fund — S 124th St and 50th PI Reconfiguration
Project No. 92510402
Transportation Improvement Board Urban Arterial Program
ISSUE
Accept a Transportation Improvement Board (TIB) Urban Arterial Program (UAP) grant for the design
and construction of S 124th and 50th PI reconfiguration in the amount of $900,404.
BACKGROUND
In 2022, a traffic calming study identified intersection improvements to control speeds, improve safety,
and address pedestrian access throughout the Allentown neighborhood. This intersection was
prioritized to mitigate traffic concerns in the neighborhood. The intersection is a 3-way controlled stop
except for the east -bound right turn slip lane from S 124th St onto 50th PI. The speed limit is 25 mph with
known speeding on both roads.
DISCUSSION
In August 2024, City staff applied to the TIB UAP to fund design, construction management, and
construction expenses related to the S 124th St and 50th Pl. road reconfiguration. In November 2024,
the City was notified that we received the full grant award. The identified solutions include removing the
east -bound right turn slip lane, requiring all vehicles to come to a complete stop, adding a highly visible
marked pedestrian crossing, and constructing protected pedestrian walkways. The specific site
elements will be further explored during the design process. The City currently has a conceptual design
(Exhibit A) and this funding will be used to support project implementation.
FISCAL IMPACT
The City was awarded a $900,404 grant from the TIB. There is a 21.8% local city match which is
budgeted in the recently adopted CIP, using 104 (Arterial Streets) Funds.

RECOMMENDATION

and consider this item on the Consent Agenda at the February 3, 2025 Regular Council Meeting.

CITY OF TUKWILA CAPITAL PROJECT SUMMARY
2025 to 2030
PROJECT:
S 124th St/50th Pl S Reconfiguration
Project # 92510402
Project Manager Cyndy Knighton Department Arterial Streets
DESCRIPTION:
Reconfigure intersection to remove EB slip lane, new c/g/s on S 124th from 49th to 51 st, new paved
shoulder walkway on south side of 124th connecting to existing walkway on west side of 50th Pl, new
stormwater treatment/rain garden in old slip lane ROW. Project can be done in phases, with phase 1
including just the intersection reconfiguration and phase 2 including the sidewalk on S 124th but cost
would be greater.
JUSTIFICATION:
Removing the free -flow right turn movement will improve safety at the S 125th St/50th Pl S intersection and
generally on S 124th St and 50th Pl S. Narrowing pedestrian crossing distance at the intersection and
improving pedestrian facilities will improve safety and livability for the neighborhood. Identified in the
Allentown Neighborhood Transportation Study in 2022.
STATUS:
New project for 2025
MAINTENANCE IMPACT: '
water treatment facilities.
If project is done in phases, the stand-alone sidewalk project could be double the cost of including them in
a single project. Approximate estimate in 2024 dollars is $600k for construction and design and
COMMENT:
construction management costs approaching $250k. Phasing the project may be necessary due to funding
constraints.
