ITEM TITLE: Council Public Safety Committee report regarding the Community
Integration Committee traffic calming recommendation
SUBMITTED BY: Scott Schafer, Public Works Director
SUMMARY EXPLANATION:
At the May 24, 2018 Public Safety Committee meeting, council members directed staff to
present the Committee's recommendation for changes in the traffic calming policy. The Public
Safety Committee's recommendation reflects full adoption of the Integration Committee's
suggested language. The Integration Committee reviewed this item per Council's request and
based on the authority provided by Ordinance 2017-034 section 1.34.020. The recommendation
has the following key elements: 1. Requirement of 30% of occupied parcels to initiate the study
process 2. 70% of occupied parcels would be required to concur with traffic calming measures
recommended by traffic study with no property requirement.
The recommendation from the Public Works Department differs from the above outlined
recommendation in the following manner: a. of the 70% needed in element 2 above, City would
require 50% affirmation from property owners.

Re: Proposed Traffic Calming Procedure
The Public Safety Committee directed staff at its April meeting to bring forth our proposed
Traffic -Calming Procedure to the Community Integration Committee for an evaluation to ensure
the petition process is fair and equitable to all residents of Yakima. On May 14 and June 11,
2018, staff presented the attached Traffic -Calming proposal to the Community Integration
Committee. The focus was on the "petitions" components of the proposal which have been
highlighted.
In accordance with the City's current procedure, only one petition step occurs; requiring
"signatures of approval" from at least 51% of the Property Owners within the immediate
affected area to officially begin the process with the City.
Under the new proposal, to initiate the proposed traffic -calming process, a resident is now
required to submit an "Initial Petition" to the City's Public Works Department with at least 30%
signature approval of the residents living within the proposed area (one signature per
parcel) for the process to begin. At this point in the process, it is not important if the signatures
are obtained from property owners or residents. The City then reviews the concern and focuses
on Education and Enforcement of the immediate area as first steps, prior to Engineering and the
installation of permanent physical measures. Public Meetings will keep residents well informed.
If it is determined that Engineering is necessary, a "Traffic Calming Petition" requiring 75%
signature approval of which at least 50% must be Property Owners (one signature per
parcel) is then required for the project to proceed.
The Community Integration Committee discussed the neighborhood participation requirements
in the proposed traffic calming procedures and offered the following recommendations to the
Public Safety Committee:
The proposed Initial Petition requiring 30% approval of residents within the area. The
Community Integration Committee discussed whether a higher or lower percentage
would be appropriate. Based on the need to establish a minimum level of concurrence
by the neighborhood and current staffing levels to analyze the conditions and conduct
the process, the Community Integration Committee decided that the 30% threshold was
appropriate as long as vacant parcels were not included in the calculation.

The proposed Traffic Calming Petition requiring 75% signature approval of which at least
50% must be Property Owners. The Community Integration Committee did have
concerns regarding the higher endorsement level if engineering was required for the
installation of physical devices if Education and Enforcement methods had not been
successful in reducing speeds. The Community Integration Committee suggested that
two-thirds (66.7%) of the parcels concur with no property owners required to agree to the
plan. Some committee members wondered why there was a petition requirement for the
construction of physical calming features at all. Their reasoning was that if there is a
safety problem, the City should just fix it regardless of what percentage supports it.
The Community Integration Committee also expressed concern regarding the public
outreach and communication with the neighborhood residents. Specifically, how do we
get our message out in a manner that relays the pertinent information to each
neighborhood? They want to ensure that there is a good notification process in place
and that staff is able to clearly communicate the issues, the process and potential
remedies. They also want non-English speaking residents involved in the process;
getting the same information.
Staff Recommendations:
Following the discussions with the Community Integration Committee, staff is comfortable in
reducing the percentage of signature approval required for the Traffic Calming Petition when
Engineering of physical devices becomes necessary from 75% to 70%.
However, staff strongly recommends that a supermajority of signature approval for the Traffic
Calming Petition be representative of property owners. This would help to avoid similar
situations such as what we experienced on 53rd Avenue where a significant number of the
parcels had new occupants between the time the petition was submitted and traffic calming
measures were implemented. The property owners were not happy. The multiple Public
Meetings should also help to mitigate this problem. With limited funding, in some cases it may
be a year or more before implementation. Because the property owners have made significant
investments within their respective neighborhoods, a commitment of approval needs to be
established with them in order to proceed with the project. As such, the new proposal would be:
70% signature approval of which at least 50% must be Property Owners (one signature per
parcel) is then required for the project to proceed.
Staff also appreciates the idea of working closely with the Community Integration Committee to
further develop its public outreach and communication process with the neighborhood residents.

Traffic Calming Procedure
1. To initiate the traffic -calming process, a resident submits an "Initial Petition" to the City's Public
Works Department. The Initial Petition requires at least 30% signature approval of the residents
living within the proposed area (one signature per parcel) for process to begin. If a council
member asks for a traffic calming evaluation for a specific location in his/her district, this begins
the Initial Petition process for the specified neighborhood; requiring at least 30% signature
approval.
2. Within two weeks of receiving the Initial Petition, Public Works staff will endeavor to contact the
requestor, following up on any needed details and/or other information.
3. Public Works' staff to conduct site visit to investigate the issue.
4. If no issues found; no action taken and City staff report back to requestor.
5. If issues are observed, City staff to focus on Education; City officials hold a Public Meeting.
Education
1. City staff to focus on alerting residents and users of the roadway within the particular
neighborhood by installing temporary signage and/or portable speed radar devices for a specific
period of time.
2. City staff to monitor and follow up with the requestor to determine if improvements have been
made. If so, determine what permanent solution such as signage should be installed and report
back to requestor. If no improvement has been observed, City staff to focus on Enforcement.
Enforcement
1. City staff to enlist the assistance of the Yakima Police Department to focus enforcement efforts
within this particular area of concern.
2. City staff to monitor and follow up with the requestor to determine if improvements have been
made.
3. If improvements have been made with no further issues; no further action to be taken by the
City and staff will report back to requestor.
4. If further improvements are needed, City staff to proceed with Engineering of traffic -calming
devices.

Residential Traffic Calming Program
Traffic conditions on residential streets can greatly affect neighborhood livability. The Residential
Traffic Calming Program (RTCP) addresses neighborhood traffic safety concerns while partnering with
citizens and/or community groups to become actively involved in the improvement process.
• First, you'll want to identify the traffic concerns in your neighborhood
• Next discuss possible solutions with your neighbors from the measures listed
in the brochure
• Fill out an online Citizen Action Request Form
• A representative from the City will contact you directly
Once the Citizen Action Request form is received, Public Works Transportation Engineering Staff will
review your concerns and begin to collect data. We will also conduct a field review of the area.
From this information, we will compile a Proposed Improvement Plan for the location and inform you
of our findings and recommendations for Phase I solutions. This review takes approximately six to eight
weeks from the date we receive your Citizen Action Request Form.
rt‘raffic Calming Strategies: 2Phase Approach
Phase Changing Driver Behavior
After an Citizen Action ' equest has been made and a problem identification and data assessment has
occurred (this step usually takes about 6-8 weeks), Engineering staff will meet with neighborhood
residents to present initial data and recommendations.
Staff and residents will agree upon which Phase 1 tools will be implemented. The length of time for this
9
step depends on residents' schedules and availability to participate.
Possible Phase I Solutions:
• Residential Speed Watch
o Volunteers will use a radar gun to clock speeds and report back to the city. Warning notices
will be mailed to speeders.
• Speed Radar Trailer Board
o A portable trailer equipped with a radar unit that detects the speed of passing vehicles and
displays it on a digital reader board. This device shows drivers their actual speed as well as
the posted speed limit, and encourages their compliance.
• Speed Radar Display Sign
o Placed in neighborhood by residents to remind drivers to slow down.
• Pavement Markings
o The painting of legends on the pavement. These may include centerlines, foglines, school
crossings, and speed limits.
• Signing
o The posting of appropriate traffic control signs. These may include speed limit, parking,
dead-end, and school signs.
• Neighborhood Tr . c Safety Campaign
o A newsletter mailed to your community. The newsletter explains volumes and speeds in your
area, recommended traffic calming measures, traffic laws, and pedestrian safety.
• Brush Trims
o The trimming and removal of brush by homeowners or City crews to allow better sight
distance.
• Target Enforcement
o Increased enforcement by the Kent Police Department.
Next Steps
Upon evaluation of Phase I, if studies indicate traffic speeds exceed the posted limit by in mph,
residents may consider Phase II.
Phase II: Physical Treatments
The City will communicate with the entire neighborhood by mailing a questionnaire on traffic issues,
including a request for volunteers to serve on a Residential Traffic Committee. The City will also mail
ballots to residents to determine the level of community support. The ballot will describe the proposal
included in the plan.
10
Design plans and cost estimates will be developed. Depending on available funding, the plan may be
adjusted. Residents will be notified of the approved plan and provided details on the anticipated
construction schedule.
• Traffic Circles
o Traffic circles are raised islands, placed at intersections, around which traffic circulates.
They are good for calming intersections, especially within neighborhoods that have major
concerns about speeds, traffic volumes, and safety.
Pictured: Mill Creek Neighborhood, between James St and Smith St. The traffic circle was
constructed in 2009.
• Speed Humps
o Generally considered the most traditional of traffic calming devices. Speed humps are raised
devices, parabolic in shape, that are placed across a residential road in a series, to slow cars
down.
Pictured: Meadow Ridge area between ll4th Ave SE and Yo8th Ave SE. A total of four speed humps
were constructed in 2006.
11
• Speed Cushions
When traffic calming measures are desired on a primary emergency response route, a newer
traffic calming device called a speed cushion may be appropriate. Speed cushions reduce
vehicle speeds but avoid excessive damage to emergency vehicles. They are designed to allow
the wider axles of fire engines and ambulances to straddle the cushions without slowing
down while forcing smaller vehicles to ride up over the cushions with at least one set of
wheels.
Pictured: Erin Glade, just north of the 277th corridor off of 111th P1 SE. Speed Cushions were
constructed in 2010 thru the City's Residential Traffic Calming Program. Erin Glade is a known
emergency response route. A total of three speed cushions constructed to slow vehicles without
slowing down emergency response times.

RESOLUTION NO. 28-11
A RESOLUTION of the City of Richland establishing
criteria to be used in reviewing neighborhood speed and
traffic calming requests.
WHEREAS, the City receives requests from citizens to install speed
bumps/humps or similar roadway features designed to reduce the speed of vehicles in
their neighborhood; and
WHEREAS, the City's traffic engineering and police patrol divisions work
together to respond to these requests with the goal of applying consistent principles and
practices aimed at ensuring safe conditions on the City's local streets; and
WHEREAS, the City desires to establish a set of criteria on which to evaluate the
need for constructing traffic calming devices in residential neighborhoods
NOW, THEREFORE, BE IT RESOLVED by the City Council of the City of
Richland as follows:
Section 1.01 The City shall continue to use education, enforcement and
engineering improvements when responding to neighborhood speed complaints from
citizens.
Section 1.02 The criteria used to determine the need and to prioritize locations
where construction of traffic calming devices are warranted shall be:
A. Speeding traffic from outside of a neighborhood (cut through traffic)
B. Speed problem is on a local street (not collectors or arterials)
C. 85th percentile speed of 35 mph or higher (this is for a 25 mph local street)
D. A crash history of five or more accidents within the last 3 years in the area of
concern
E. Not a high use school or transit bus route
F. 70% majority of area residents in favor of installing traffic calming device(s)
A street meeting A, B, C, E and F will qualify for installation of traffic calming
devices and initiate the process of identifying the cost and available funding for
the selected solution, Criteria D may be substituted for criteria C for the
purposes of qualifying for traffic calming devices, except that a street meeting
criteria D will initiate a focused safety review by the City that may result in a
different focus than speed nnitigation.
Section 1.03 This resolution shall take effect immediately.
Adopted 6/21/2011 1 Resolution No. 28-11

Neighborhood Traffic Calming Program
The City recognizes that residential streets occasionally have higher speeds and traffic
volumes due to shifting traffic patterns and new developments. Isolated, occasional and daily
conditions of high speed can affect neighborhood livability. With help from citizens and the
City's efforts in education, enforcement, and engineering, these concerns can be addressed.
View the City of Kenmore Traffic Speed Mitigation Policy flowchart.
Citizen involvement and data collection are integral parts of all traffic calming projects. The
people who live and work in the area of concern have the opportunity to become actively
involved in the planning and decision making process.
The City takes regular traffic speed data on arterial roadways and has been collecting speed
data on residential roadways in response to concerns. You can check to see if speed on your
street has recently been measured here.
What is the Neighborhood Traffic Calming Program?
The Neighborhood Traffic Calming Program addresses neighborhood traffic concerns identified
by citizens and/or community groups. Through active participation by citizens, we can identify
the problem, plan the approach, implement solutions, and evaluate their effectiveness.
The City's traffic calming toolbox includes three categories of solutions referred to as the three
Es: Education, Enforcement, and Engineering.
• Education alerts citizens to ways they can help ease traffic problems in their own
neighborhoods. This can include temporary radar devices, direct mail campaigns,
newsletter articles and temporary signage.
• Enforcement enlists the help of the Police Department to focus enforcement efforts
on the area of concern and increase community awareness of speeding problems
through their presence.
• Engineering tools include a variety of traffic calming physical devices that can reduce
speed or improve safety. These tools are used only after a data -driven analysis and
pursuit of the other two "E"s in an attempt to alleviate the problem.
The City will look to citizens to help identify specific neighborhood characteristics that should be
taken into account when identifying solutions. Solutions will be evaluated to ensure that they
serve all neighborhood users, do not negatively affect emergency access and other public
services, and, in the case of physical devices, have support of a majority of the residents who
will be affected.
15
^ Pedestrian and bicycle safety and mobility barriers
In the case of each of these situations, citizens should notify the city, and this will initiate the
process. A Citizen Action Request may be submitted via the online form on the city website, by
phone or by fihling out a form at the front desk. Collection of data will be scheduled by the city,
and after tabulation and analysis of the data on recorded speeds and volumes, citizens will be
involved in the selection of tools that are appropriate to alleviate any excessive speeds or
imbalanced volumes.
What can be done now to address vehicle speed concerns in residential areas?
~ Neighborhood Speed Watch Program: This program allows citizens the opportunity
to check out a radar unit and record the speeds of vehicles traveling in their
neighborhood. Radar units available include both a handheld radar gun and a radar
• Speed radar trailer: A portable trailer equipped wita radar unit which
detects the speed of passing vehicles and displays it on a digital reader
board. This device shows drivers their "actual speed versus the posted
speed limit and encourages their compliance.
• Radar guns: Handheld devices which allow citizens to determine and
record the actual speeds of vehicles on their strets. Requires the use af
safety equipment to notify drivers of the citizen speed watch to ensure the
safety of drivers and neighbors.
Neighborhood Newsletter: This program involves a personalized newsletter mailed
to your community. The newsletter explains traffic volumes and speeds in your area,
refreshes citizens on traffic laws and pedestrian safety, and encourages compliance.
°
Target Enforcement: Increased enforcement by the Police Department, Traffic
section.
What can be done in the future?
If data collection confirms an issue of excessive speeds, volumes, or rate of collisions, the
installation of traffic control devices will be considered. Each of these devices is unique and
specilic criteria have been established for when and where they may be used. Physical in -road
devices can also have other impacts on emergency services, neighborhood noise, and
diversion of trafflc to other nearby routes.
Other tools for addressing concerns can include road striping revisions, street signage revisions
and operational revisions. Use of the most appropriate tools is determined by traffic
engineering analysis by city staif. Vehicle volume thresholds in the collected data must be
between 300 and 3000 vehicles per day to be considered in the Calming Program. Volumes
outside of this range are either too low for devices to be effective when compared with
°

▪ The engineering standard for assessing speed on a road is the speed at
which 85% of all vehic!es are measured to be at or below. This is ca!Ied the
85th percentile speed. This speed is higher than the average speed of all
vehicles and encompasses the majority of all drivers. See if traffic on your
street has recently been measured here.
• 85th percentile speeds between 5 and 10 miles per hour over the posted
limit are of concern, but are stronger candidates for educatiori and
enforcement before physical changes are considered.
• 85th percentile speeds in excess of 10 miles per hour over the posted limit
are considered excessive and are good candidates for physical changes
after an engineering analysis of the roadway.
^ High rate of 3 -year collision history
°
A collision rate of more than one per year for the Iast three years is
considered to be of concern and would Iead to an analysis for physical
changes.
Based on the data collected and the topography of the area, tools to address traffic concerns
may be recommended. Any recommended action will be based on sound engineering and
planning principles. Safety remains paramount in the decision-making process, including
access for public safety vehicles. To ensure there is consensus among citizens that would be
directly affected by these changes and the potential impacts they may have, neighborhood
meetings will be held and majority support (60%) is required before proceeding with
construction of the physical devices.
How does this program differ from the Neighborhood Transportation Plans
The Neighborhood TrnuportationP|mnoPmgnom<NTPP>.dhndmoi|uofwhiohuanbohuundat
this link, is a collaborative engagement of citizens within defined Kenmore neighborhoods to
address traffic and mobility problems proactively. The NTPP will be collecting input primarily in
late 2015 and into early 2016. There may be issues which are not raised during this process, or
which occur after this process which are candidates for the Calming program. During the initial
rollout of the NTPP, requests to engage in the Calming program will be directed to the
NTPP. The Calming program will revert to being the primary means of addressing citizen
concerns following the completion of the NTPP for each Kenmore neighborhood.

TRAFFIC CALMING PROGRAM POLICY
Citizen Action Request
The citizen requesting action or expressing a concern will be asked to complete a Citizen Action Request
Form. When completing the form, descriptive items are helpful such as: time of day, type of vehicies,
specific location, concern for pedestrians and cyclists, concern for parked vehicles, vehicles entering the
roadway or motorists losing control of their vehicles, etc.
First Response Level
City staff will prepare an initial response acknowledging receipt of the request and identifying the
immediate action that will be taken. The immediate action may include researching the issue, a field
trip to the site, or referral to another entity. The requestor should also be informed if the problem has
been previously reviewed and any actions taken.
Second Response Levet
City staff will investigate the request, looking into any data on hand to support the area of concern such
as previously conducted speed studies and historical collision database searches. City staff will make a
field visit to the site or virtual investigation using mapping software to observe existing geometric and
physical conditions. Observatioris wil! be niade of existing signage and striping. Observations wiH be
made of any in-place speed control devices on this or any connected, neighboring streets that could be
causing traffic diversion.
If one or rnore of the foliowing existsthen action will be deferred:
°v
The street is an arterial. Based on Iimited resources and the need for rnore exterisive speed
control measures on arterials due to higher volumes, the City has focused its efforts on
residential streets for this program, City staif will inform the Police Chief of the concern and ask
for some additional traffic enforcement. City staff will record the request and continue to
monitor the situation. Concerns on arterials may be factored into future Capital Improvement
Plan (CIP) budgets and identificatlon of projects.
• Historical speed data records less than three years old show speeds that do not meet the
criteria, described below, for concern and/or the street has had less than three complaints
about speeds from different households in the past three years. ThIs may be an isolated
occurrence or precursor to a continuing problem and City staff will record the request and
continue to monitor. The Street may be scheduled for future speed data collection if resources
are available and existing data is outdated or unavailable.
°m Historical volume records less than three years old show volumes less than 300 or greater than
3000vehicles per day. Streets with Iess than 300 vehicles are more effectively addressed
through education and enforcement due to very low volumes. Streets with more than 3000
vehicles should be considered as arterials.
18
• The street isolocal access street less than 600 feet long with a cul-de-sac. City staff will verify
that the appropriate traffic control signage exists at the nearest intersection. This signage,
combined with the short length of the streetshould mitigate the problem. However, City staif
will record the request and continue to monitor.
* The request appears to be an issue between two individuals. City staff will refer the matter to
the Police Chief and continue to monitor.
Excessive Speed Criteria
The 85th percentile speed is an accepted engineering practice which evaluates streetsbased on the
speed that 85 percent of all vehicles were measured at or below. This speed is above the average speed
of all vehicles, and encompasses a majority of all drivers on a roadway.
If the 85th percentile speed is 5 miles per hour or lesabove the posted speed limit, no action is
required. This is considered to be within the limits of human and instrument error and indicates that
drivers are following the posted speed limits.
If the 85th percentile speed,is between 5 and 10 miles per hour over the posted speed limit, education
and enforcement measuressuch as a neighborhood watch progrm using radar devices available at City
Hall for citizens to check out, would be warranted. Neighbors would be encouraged to visit each other
and express concern for problem; newsletters could also be sent out regarding the problem. The Police
would be notified of the concern in the area and perform additional enforcement when resources allow.
If the 85th percentile speed is 10 miles per hour or more over the posted speed limit, speeds are
considered excesive. City staff will request traffic enforcement from the Police Chief. City staif will also
analyze the available traffic calming tools, including physical devices, revisions to striping and signage,
and operational revisions, to address the concern.
If one of the following exists, then the City would proceed to the third response level:
* Historical automated traffic counter data less than three years old shows 85th percentile speeds
that exceed 10 miles per hour over the posted limit.
o Streets with high volumes of pedestrians and cyclists, on Safe Routes to School, or with
a higher population of other vulnerable non -motorized users will be considered for the
third response level with 85th percentile speeds between 5 and 10 miles per hour over
the posted limit.
• There have been more than three requests for action from different households in the past
three years
�
The Police Chief requests action to be taken after additional enforcement
= Three or more reported traffic collisions in the past three years.
19
Third Response Level
At the third response level, the City will consider physical revisions to the roadway, including in -road
physical devicesstriping and signirig, and operational revisions in an effortto reduce speeds. Examples
of devices that could be instaHed include:
w
Traffic humps, cushions and raised crosswalks: mounded pavement material that spans the
roadway, approximately 4 to 6 inches above the existing surfaceforces slow -downs and can
provide an improved pedestrian crosin0. These devices have a significant impact on emergency
service response times, and can cause increased noise to neighboring properties.
Curb extensions: construction of landscaped appendages on the side of the street narrowing the
street width to one or two lanes, both at intersections and mid -block. These devices reduce
crossing width for pedestrians.
�
Traffic circles: a small circular island placed in the center of a street intersection forcing traffic to
make a slow turn around it. These devices can have a signfflcant impact on emergency service
and deIvery vehicles.
Chicane: a narrowing and twisting of the roadway for several hundred feet using curbs and
Iandscaping within the existing right-of-way. These devices can have a significant impact on
emergency service and delivery vehicles.
The City will consider the presence of Safe Routes to School routes, designated or highly used cyclist
routes, the characteristics of the concern and the characteristics of the neighborhood when analyzing
streets for traffic calming devices orother physical changes. Engineering analysis of potential changes
will consider:
• The likely impact ofthe change to address the concern
�
Impacts to emergency services
~^
Impacts to neighboring streets that may see diversion
lmpacts to transit service
Changes will be made in a context -sensitive manner and will seek neighborhood consensus prior to
iristallation of changes. Any in -road physical device wiD require a neighborhood petition with 60%
approval of residents within% mile of the device, and 75% approval of residents immediately adjacent
to the device.
The City will pursue temporary changes whenever possible, and will evaluate all changes after a
minimum of 90 days for effectively addressing the concern. Temporary changes that are effective may
be changed to permanerit installations if warranted after the minimum 90 day period.
