A RESOLUTION of the City Council of the
City of Kent, Washington, repealing Resolution No.
L8L7 and adopting a new Residential Traffic
Calming Program to better address quality of life
concerns related to traffic in residential
neighborhoods by considering traffic speeds and
cut-through traffic as well as other neighborhood
factors.
RECITALS
A. Residential streets within the City of Kent have measurable
safety and community character impacts due to the speed and volume of
through traffic. Through Resolution No. 1546, adopted on July 6, 1999, the
City has addressed these impacts by the Residential Traffic Calming
Program (*RTCP"). The City has made adjustments to the RTCP at various
times, most recently with the adoption of Resolution I8t7, adopted on
October 20,2009.
B. The Mayor and City Council recognize the need to update and
revise the means by which residential traffic impacts are addressed, and
have directed the City's Public Works Department to consider proven
solutions that include resident involvement. In response, the Department
conducted research on residential traffic calming efforts throughout the
United States and developed the RTCP.

C. The RTCP is general in nature, establishing overall policies and
approaches, but leaves the specific details of implementation to the Public
Works Director, in order to adapt program implementation to meet
neighborhood needs on a more flexible case-by-case basis. This program is
designed to evaluate a wide variety of factors that negatively impact the
safety and quality of residential environments. These factors include traffic
speed, volume, crash history, pedestrian facilities, and prominent
neighborhood features. This program will allow residents to identify
problems and solutions specific to their neighborhoods with the help of City
staff. If a neighborhood qualifies, potential traffic calming measures will be
considered, including the construction of physical devices to reduce traffic
volumes and speeds. Installation of physical devices shall be based upon
sound engineering and transportation planning principles and with regard
to neighborhood aesthetics. The RTCP will provide for periodic evaluation of
the solutions as implemented and may include follow-up surveys to
determine project effectiveness and resident satisfaction.
D. The updated RTCP creates a more stream-lined and
responsive approach by eliminating the two-phase program. Phase one of
the current two-phase program requires resident involvement that may
impact personal safety and does not reduce traffic speeds long-term. This
phase also requires additional data collection and analysis that delays
formal evaluation and creates additional steps for residents that
discourages further participation in the program. This new approach
maintains transparency, while allowing discretion and flexibility when
warranted. The result is a process that is data driven, prompt, and more
user-friendly.
E. On March 24, 2O2O, the Committee of the Whole heard a
presentation regarding the RTCP. On May 26, 2O2O the Committee of the
Residential Traffic Calmi ng

EXHIBIT A
RESIDENTIAL TRAFFIC CALMING PROGRAM
The City of Kent Residential Traffic Calming Program (RTCP) was first
adopted in July of 1999. The program was established to guide City officials
and inform residents about the processes for implementing traffic calming
on residential streets. It has been more than a decade since the program
was last updated in 2009 (Resolution 1817). Since then there has been a
concerted effort to continue to streamline these processes.
The 2020 update eliminates the need for the two-phase approach
previously used in which a variety of passive control devices were first
employed and then physical alterations to the street were considered.
Instead, the update establishes clearly defined decision points and
thresholds. This new approach maintains transparency, while allowing
discretion and flexibility when warranted. The result is a process that is
data driven, prompt, and more user-friendly.
Program Elements
1. Eligibility
The RTCP is designed to address neighborhood traffic concerns on
residential streets, both local streets and residential collector streets.
Request for Action
Residents may contact City staff via letter, phone, email, or an
online form such as the Residential Traffic Calming Citizen Action
Request Form to request the installation of traffic calming measures.
Gathering Support
Early neighborhood engagement is key. A minimum of five residents
are required to initiate the process by filling out an online form or
contacting City staff directly.

City Response to Request for Action
City staff will follow-up with the residents that initiated the request
for action, typically within 48 hours, to discuss next steps.
Data Collection and Evaluation
In consultation with the residents, the City Traffic Engineer will
define the study area. The City will then conduct a traffic study to
determine if the minimum requirements are met to qualify for the
installation of traffic calming devices. As part of the traffic study,
points will be awarded based on characteristics of each street as
outlined in Table 1, which assigns points based on the following
factors:
a
a
a
a
Traffic Speeds: The 8Sth-percentile of all vehicles in
both directions over a 7-day minimum period, points
awarded by the number of mph over the posted speed
limit.
Average Daily Traffic (ADT) Volumes: The average
number of vehicles per day in both directions over a 7-
day minimum period.
Cut-Through Traffic: A measured imbalance where the
ADT in one direction is 2.5 times greater than the other
direction.
Crash History: The most recent 5-year crash data from
the WSDOT Crash Data Portal; points awarded for each
crash.
Pedestrian Facilities: The typical presence of sidewalks
or separated shoulder walkways.
Park, School (K-Lz), or Transit Stop: The presence or
proximity of these features or presence of a school
walking route on the study street. Use the highest
scoring criteria from this section.
a
a
A minimum total score of 50 points is required to move forward with
consideration of traffic calming measures. If the total score is less
than 50 points, the City will work with the neighborhood to identify
appropriate education and enforcement strategies.
Validation of Traffic Study Results
If the minimum point threshold is met, a minimum of two speed
studies, conducted at least 8 weeks apart, are required before
moving forward with engineering recommendations. Traffic speeds
and volumes in the second study must be within 10 percent of the
original study to validate the results. If the speeds and volumes of
the second study are not within 10 percent, a final third study will be
conducted.
Reconsideration of Requests for Action
Requests for action that were not successfully implemented in
previous attempts will only be reconsidered in the following
instances:
. The proposal was not implemented due to budget
constraints and the minimum points required continue to
be met.
. Traffic conditions have changed due to roadway
improvements or land use changes, as determined by the
City Traffic Engineer.
o At least 36 months have passed since the previous request
for action that failed to meet the minimum points required.

Staff will share the results of the traffic study with the residents and
discuss strategies and next steps. Strategies include a combination
of education, enforcement, and engineering. If the request for action
meets the minimum points requirement and qualifies for traffic
calming measures, the City will hold a neighborhood meeting to help
determine the preferred types of traffic calming devices and their
approximate location.

All traffic calming measures are subject to approval by the City
Traffic Engineer, School District Transportation Department, Kent
Police Department, and the Fire Marshall.
The Public Works Director has the discretion to move an application
forward or to address safety issues discovered outside of the RTCP
process.
Neighborhood Voting and Notification
After the meeting, the City will mail a ballot to affected residents
within the study area, allowing those residents to vote on the traffic
calming measures the City recommends be installed. The City
requires a 50o/o ballot return rate and a two-thirds majority approval
of the returned ballots is required before any traffic calming
measures will be installed. Residents will be notified of the ballot
results and if applicable, the approximate construction timeline.
Installation
City engineering staff will design the traffic calming measures and
develop a plan to install them.
Evaluation and Follow-up
A follow-up study should occur at least 6 months after installation.
Traffic speed and volume data should be collected and any change in
traffic volumes and speeds on the treated streets documented.
