FROM: Hari Ponnekanti, Public Works Director
BY: Cyndy Knighton, Senior Program Manager — Transportation
CC: Thomas McLeod, Mayor
DATE: April 19, 2024
SUBJECT: Neighborhood Traffic Calming Program On -Call Contract
Project No. 82110301
Supplemental Agreement #1
ISSUE
Execute a supplemental agreement with KPG (dba Psomas) to provide on -call engineering and
design services for the Neighborhood Traffic Calming Program (NTCP).
BACKGROUND
Since 2021, staff have been working on projects identified in the Staff Top-10 Recommended NTCP
Projects. Three projects have been fully completed: Allentown Neighborhood Speed & Safety Study;
Tukwila Community Center Pedestrian Crossing Safety Improvements; and S 144th Street/46th
Avenue S ADA Ramps. Three others are nearly completed, pending a final discussion with the
schools: Tukwila Elementary School Safety Improvements; Cascade View Elementary School Safety
Improvements; and Impact Charter School Safety Improvements. Macadam Road Speed and Safety
Improvements and a City-wide review of speed limits have already been assigned to KPG to conduct.
Southcenter Boulevard/65th Avenue S Pedestrian Safety Improvements has been changed to a new
traffic signal installation, with design underway and construction in 2025. The last remaining Staff Top-
10 project to complete is the S Ryan Way Pedestrian Safety Improvements.
ANALYSIS
After further exploration regarding S Ryan Way, staff has determined the needs surpass the original
plan. In addition to the identified safety concerns, the road routinely develops potholes that must be
fixed regularly by the street crew. A large senior housing development is under construction south of
S Ryan Way off 47th Ave S that may warrant a traffic signal. A full CIP project must be developed, and
funding acquired. To do this additional work, the contract budget for the on -call project with KPG
needs to be increased.
FINANCIAL IMPACT
Funding is fully available under the current budget.

C Impact Charter School Safety
Improvements
A request specific to the newly opened Impact Charter School was received in 2019. The request was to provide a signed
school zone, which Tukwila has provided signs marking school crossings on S 148th Street. ADA-compliant ramps have not
been installed at the marked school crossings. The charter school has expanded their site to the north which requires
creating a school zone on S 146th Street and other potential improvements for children's safety. Additionally, the Council
has asked for proactively addressing or anticipating concerns, specifically around school zones.

E Tukwila Community Center
Pedestrian Crossing Safety
Improvements
The City Council has expressed desire for the NTCP to have a proactive element in addressing traffic calming and safety
needs throughout the City. The TCC is a well -utilized facility by the Allentown neighborhood as well as the entire City and
surrounding area. Concerns over the pedestrian crossings on S 124th Street have been raised by staff and residents in the
past, along with the larger complaints of speeding in Allentown. Increasing pedestrian visibility to improve safety in this high-
use area is a recommended top priority for the NTCP.

F Macadam Road Speed and
Safety Improvements
At least five requests for traffic calming, specific to speeding (and some secondary reasons) have been made since 2018. A
radar feedback sign was placed near the 13700 block in 2019 but requests have continued to be made. Additional analysis is
warranted to determine what other improvements could be used to address the speeding, especially where Macadam Road
has extremely limited sight distance due to the curvy nature of the roadway.
• Design to begin in 2/3Q.
$10,000 - 30,000
TBD
$10,000 - 30,000
Design and install treatments addressing speeding and curve
safety north of S 144th Street.
Level 1: Improved signage; LED chevron signs; channelization
modifications.
Level 2:
G Southcenter Boulevard/65th
Avenue S Pedestrian Safety
Improvements
Staff identified the need for improvement pedestrian safety at this location several years ago. Southcenter Boulevard is a 5-
lane roadway with known speeding issues along with curves that restrict sight distance. A high pedestrian usage at this
intersection accessing the King County Metro bus stop that services both the Rapid Ride F-Line and Route 150, both
workhorses of the south County transit network, justifies improving pedestrian crossing safety. This intersection is slated for
full signalization in the future, but interim pedestrian safety improvements should be considered sooner.
• Funding available for design of full
signal in 2022 CIP.
• Design to begin in 2022.
• Will consider signage
improvements for interim in 2/3Q.

H City-wide Residential Speed
Limit Review
As part of the City Council's expressed desire to proactively look at traffic calming needs, a full review of the residential
street posted speed limits is recommended by staff. State law establishes city speed limits at 25MPH unless an engineering
study is completed to justify higher speed limits. Most residential streets are posted at 25MPH today, but there are many
that are posted at 30MPH or 35MPH. Likely, those speed limits are legacies of past annexation areas, where a speed study
was completed by King County. The general impression Staff has is that most residents and elected officials would be
happier with lower speed limits. City of Seattle has also recently lowered all speed limits nearly city-wide to be 25MPH.
• Not started yet.
$5,000-8,000
TBD
$5,000-8,000
Identify residential streets with speed limits currently above
25MPH. Conduct volume, speed and safety review.
Recommend changes to speed limits, as necessary.
Level 1: Modify speed limit ordinance; as needed; install new
signs; as needed.
Level 2:
I S Ryan Way Pedestrian Safety
Improvements
Two requests for traffic calming to address speeding and pedestrian crossing safety in the Ryan Hill area have been made in
2021. New developments are coming forward that will increase the residential population of this part of the City with multi-
family developments. The speed concerns, especially along S Ryan Way, coupled with the new housing developments
increasing the likelihood of increased pedestrian activity, warrants this analysis be recommended as a top priority.
• Transportation Safety Study for
improved signage and safety
improvements may begin in 2/3Q.
• Construction of improvements
possible in 2023.
$10,000-100,000
TBD
$10,000-100,000
Safety study on S Ryan Way from MLK Jr. Way to east city
limits, focusing on speeding and pedestrian safety.
Recommend Level 1 and Level 2 improvements. Design and
construct improvements.
Level 1: Improved signage.
Level 2: Curb extension, improved illumination.
J S 144th Street/46th Avenue S
ADA Ramps
The Tukwila School District requested school crossing safety improvements at this intersection in 2017. A new Rectangular
Rapid Flashing Beacon was installed in 2019. At the time the RRFB was installed, the City was also submitting a grant
application for the 46th Avenue S Safe Routes to School project, which would improve pedestrian safety between this
intersection south to S 150th Street, and would include either a raised pedestrian crosswalk at the RRFB or install ADA-
compliant curb ramps. The grant was not awarded. State law requires ADA ramps be brought up to current standards
anytime a new signal, including the RRFB, is installed. Since grant monies for the larger improvement are not expected in the
short term, staff recommends this as a priority to comply with all state and federal laws regarding ADA requirements.
• Design at 50% with construction
to be done with the 2022 Annual
Overlay Project.
$15,000-20,000
$15k PE
$90k Construction
$105,000
Design and install ADA-compliant ramps at the intersection.
Level 1:
Level 2: ADA upgrades to ramps at RRFB (not done at time of
