Report regarding Library Board Interviews and Appointments. (Krista Martinelli, City Clerk).
RECOMMENDATION
It is recommended that the City Council consider the attached citizen applications for appointment to the
open seats on the Library Board.It is further recommended that upon completion of interviews,Council
move to appoint two (2) individuals to respective seats on the Board.
BACKGROUND/DISCUSSION
Pursuant to Resolution No.27-2009,the City Council holds biannual recruitments/meetings for the purpose of
considering appointments to Boards and Commissions.In August 2018,due to expiration of terms and
resignations,the City Clerk’s Office initiated recruitment for several Boards and Commissions.Due to low
application turn-out for the majority of the positions,the recruitment has been extended for openings with the
exception of the Library Board.The Library Board had a sufficient number of applications and a more pressing
need for appointments in light of a vacancy and term expiration.
Summary of Library Board openings:
•Trustee Lambertson resigned for residency reasons.
•Trustee Hansen’s term expired June 6, 2018 and she is not eligible to reapply due to term limits.
Library Board Duties and Meeting times
The Library Board meets on the fourth Tuesday of every month at 6:00 p.m.at the Main Library.Trustees are
appointed to a three (3)year term with a limit of appointment to four (4)consecutive terms.The Library Board

Presentation of the Citywide Neighborhood Traffic Management Policy and Procedures.(Richard Cho,
Principal Engineer and DKS & Associates)
BACKGROUND/DISCUSSION
In recent years,Department of Public Works staff fielded an increasing number of complaints and concerns
from community members regarding neighborhood traffic.These concerns include excessive vehicular traffic
and speeding on local and collector streets in residential areas.The City will soon install speed cushions in the
Avalon-Brentwood neighborhood.This is a culmination of a three-year process that involved installation and
removal of temporary traffic calming devices as part of a pilot project,preparation of a neighborhood traffic
calming plan that included installation of signs and striping,installation and removal of a traffic circle,and
extensive public outreach which included three community meetings.
Over the past two years,the City received frequent requests for traffic calming from residents across the entire
City.It became apparent to City staff that there was a need for a standard policy and process.The purpose of
developing a standard policy and process was to bring consistency and fairness to addressing traffic calming
requests,to set objective standards,and to provide guidance to the public and City staff on the procedures to
follow.
Policy Overview
The proposed policy was developed using the following objectives:promote safe and convenient travel for
pedestrians,bicyclists,and motorists;encourage speed limit compliance;reduce cut-through traffic in
residential neighborhoods;balance neighborhood traffic calming with public safety with respect to emergency
response times;and apply the correct traffic calming measures that appropriately address identified traffic
problems.The proposed Neighborhood Traffic Management (NTM)program will apply only to a subset of City
streets.These include local and two-lane collector streets with predominantly residential uses,local and two-
lane collector streets fronting schools,community centers,religious institutions,or parks,and some selected
minor arterial segments in residential areas.
A toolkit of traffic calming measures was developed to address neighborhood traffic calming concerns.The
toolkit is divided into two tiers.Tier 1 measures include signs,pavement markings,and roadway striping.Tier 2
measures include physical traffic calming devices such as speed cushions,curb extensions,traffic circles,and
mini-roundabouts.Tier 1 measures may be implemented through a review and approval process within the
Department of Public Works.Tier 2 measures,which are costlier and potentially more controversial,will
require a neighborhood vote to implement.
Neighborhood Traffic Management Process
The proposed process for addressing neighborhood traffic calming requests and concerns are shown in the
attached flowchart.To initiate the process (Step 1),a community member will fill out and submit a standard
Traffic Advisory Committee (TAC)form.If the concern is NTM-related,the community member will be
directed to gather at least ten signatures of support on a Neighborhood Traffic Calming Petition (Step 2).Upon
receiving the successful petition,City staff will conduct an assessment and collect data (Step 3).To proceed to

Version:1 Item #:2.
the next step, the location in question must meet at least one of two criteria:
·Speeding: 85th percentile speed exceeds posted speed limit by at least 7 mph
·Cut-through traffic volumes: 1,000+ vehicles per day
If the criteria are met,the City will prepare an NTM plan for the area in question (Step 4).This plan may
include both Tier 1 and /or Tier 2 measures.Plans will be prepared looking holistically at the neighborhood
rather than focusing on a single street to ensure that traffic problems are not simply shifted from one street to
the next.
The proposed NTM plan will be presented to community members via mailers and,optionally,a neighborhood
meeting (Step 5).The City may revise the plan based on feedback received from the public outreach effort.
Before implementing any Tier 2 measures,the City will ask for a vote from affected residences and property
owners.An affirmative support of two-thirds of the responses received will be required before installing any
Tier 2 measures (Step 6)such as speed cushions.If an affirmative support is not received,then only Tier 1
measures will be installed.
Tier 1 measures will be funded from the City’s annual TAC budget on a first-come,first-serve basis.If traffic
calming requests approved in a single year exceed the TAC fiscal year budget,then such requests will be placed
in a queue for the following fiscal year.Tier 2 measures will require approval from the City Council as funding
sources will need to be identified and appropriated.An optional step is follow-up data collection to determine
whether the installed traffic calming devices are adequately addressing the problem or whether further
consideration is needed for additional measures.
CONCLUSION
The Department of Public Works staff has worked with a traffic consultant, DKS and Associates, to develop a
draft Neighborhood Traffic Management Policy and Procedures document that is the topic of this study session.

1.1 TRAFFIC CALMING OBJECTIVES
The City of South San Francisco is implementing this
NTM policy with the following objectives:
• Promote safe and convenient travel for
pedestrians, bicyclists, and motorists;
• Encourage speed limit compliance;
• Encourage through traffic to use major
arterial routes rather than cutting through
residential neighborhoods;
• Work with the Police and Fire Departments
to balance neighborhood traffic calming
with public safety, specifically with respect to
emergency response times; and
• Apply the least restrictive, least expensive traffic
calming measures that are appropriate to
address identified traffic problems.
1.2 NTM ELIGIBILITY
The NTM policy and program applies mainly to local
and two-lane collector streets with predominantly
residential uses. Local and collector streets that front
schools, community centers, religious institutions,
or parks would also be eligible for neighborhood
traffic calming. A limited number of streets classified
as minor arterials would also be eligible for the
program. These selected minor arterial segments
have predominantly residential, park, community
center, or school uses, unsignalized intersections,
and no more than one travel lane in each direction.
Figure 1 shows the roadway classifications of streets
within the City as identified in the City’s General Plan.
Figure 2 highlights those street segments eligible for
the NTM program.

INTRODUCTION
This document presents neighborhood traffic
calming policies for the City of South San Francisco.
In recent years, City of South San Francisco officials
have heard from community members across
the city with concerns over excessive speeds and
increasing volumes of traffic on residential streets.
Much of the increased traffic is believed to come
from “cut-through” traffic using neighborhood
residential streets as an alternative to nearby
congested arterials.
Managing these traffic concerns requires a balance
between neighborhood quality of life, legitimate
use of public streets, and use of City resources.
This Neighborhood Traffic Management (NTM)
policy is intended to provide a transparent, fair, and
consistent process for addressing neighborhood
traffic concerns, as well as for identifying and
implementing traffic calming projects in residential
neighborhoods throughout the city. The NTM
policy is intended to accommodate neighborhood
input, and seeks to build consensus on traffic
calming policies and plans. Finally, the NTM policy
identifies objective criteria for NTM eligibility and
the prioritization of projects.
This NTM policy is intended to address only
concerns regarding excessive speeds and traffic
volumes in residential neighborhoods. All other
traffic concerns, such as requests for parking
restrictions, will continue to be addressed by
making a request to the City’s Traffic Advisory
Committee (TAC).

1.3 TRAFFIC CALMING TOOLKIT
There are three main approaches to addressing excessive speeds
and volumes on local residential streets: education, enforcement,
and engineering. City staff will evaluate each traffic calming request
to determine where education (outreach to community groups or
institutions) is appropriate and where coordination with the Police
Department would be beneficial. The “engineering” approach
consists of physical improvements or devices designed to slow or
deter motor vehicle traffic. These physical improvements range
from relatively simple and inexpensive measures such as additional
signage to more involved projects such as speed cushions or
traffic circles.
The measures in the traffic calming “toolkit” for South San
Francisco have been broken down into two tiers:
• Tier 1 includes relatively low-cost and less obtrusive measures
such as signs, pavement markings, and roadway striping that
could be implemented at the discretion of Department of
Public Works staff.
• Tier 2 includes more extensive measures such as speed
cushions, curb extensions, traffic circles or mini-roundabouts
that would require neighborhood input
before implementation.
The measures in each tier are presented in Table 1 and 2,
respectively.
Note that the traffic calming toolkit does not include the addition
of stop signs to intersections. Stop signs are not appropriate tools
for traffic calming and should be installed only where warrants
specified in the Manual on Uniform Traffic Control Devices are met.
Adding unwarranted stop signs can induce non-compliant behavior
by motorists.

Education and
Enforcement
Strategies
Public outreach and education
campaigns
Public meetings, mailers, social media
campaigns and other methods to encourage
good driving behavior and awareness of
vulnerable populations.
Traffic speed • Relies on personal responsibility rather
than law enforcement
• Can improve neighborhood cohesion
• Relatively low-cost
• Limited audience (would not impact
drivers from outside neighborhood)
Varies but
generally low
Speed Radar Trailer Speed radar trailers remind drivers of their
speed with respect to the posted speed limit
and can be paired with police enforcement to
increase compliance.
Traffic speed • Trailers are mobile and can be quickly
deployed when and where needed
• Moderately effective when combined
with enforcement
• Inexpensive
• Trailers are bulky and require at least
one parking spot
• Require active enforcement or drivers
will learn to disregard
• Effectiveness will dissipate over time
after trailers are removed
Minimal (the City
currently owns
two speed radar
trailers).
Signage Regulatory signage Speed limit signs, parking restrictions, vehicle
type restrictions.
Note: this measure is intended to remind
motorists of existing regulations. Changes
to speed limits must follow a prescribed
regulatory process.
Traffic speed • Reminds drivers of traffic laws such
as speed limits, parking restrictions,
or truck restrictions where signage is
currently lacking
• Inexpensive
• No increase to street maintenance
costs (applies to all signage measures)
• Effectiveness can wane over time as
drivers become used to additional
signage
Low
(approximately
$200 per sign)
Regulatory Signage Turn restriction signs prohibit specific
movements on neighborhood streets.
Examples include left or right turn restrictions.
Traffic volume • Cost-effective means of reducing cut-
through traffic
• Redirects traffic to main streets where
higher traffic volumes are acceptable
• Can be limited to certain times of the
day (i.e. peak commute hours)
• Possible traffic diversion to other
neighborhood streets
• Adds signage to the neighborhood
• Can limit access to the neighborhood
• Affects neighborhood residents as well
as cut-through traffic
• Requires enforcement
Low
(approximately
$200 per sign)
High-visibility signs Upgrades existing signage with higher visibility
versions. This can be done using a fluorescent
yellow-green background on applicable signs,
as well as flashing lights either above or below,
or integrated into the sign.
Typically, these flashing lights are the
same color as the background of the sign
(flashing red on stop signs, flashing yellow on
pedestrian crossing signs, etc.).
Traffic speed • Increases visibility of an existing sign
making it more prominent to the
passing driver. The sign is less likely to
“blend in” to the surroundings
• Inexpensive
• Can bring attention to a troubled area
at night, where an existing sign might
be poorly illuminated
• May not address root concern
• May increase driver distraction
Medium
(approximately
$2,000 for solar
powered sign)
Speed feedback signs These signs are a more permanent version of
the speed radar trailer described above. Like
the trailer, they remind drivers of the speed
limit by broadcasting the vehicle’s speed as it
passes, compared to the limit.
Flashing speed feedback signs flash a bright
light when the speed limit is exceeded.
Traffic speed • Public display of excess speed to
drivers
can be effective in reducing speeds,
especially when combined with
targeted enforcement efforts
• Requires little space compared to
speed feedback trailers
• Can lose effectiveness over time as
drivers become used to permanent
speed
feedback signs
• Vulnerable to vandalism
• Flashing signs may be inappropriate for
residential streets due to light exposure
impacts
High ($8,000-
$12,000 for solar-
powered sign;
$15,000-$20,000
for flashing sign)

Category Traffic Calming Measures Description Examples Concern Addressed Advantages Disadvantages Cost Range
Roadway markings Speed legends Speed legends painted on the roadway can
catch the eye of drivers who might miss the
sign posted on the side of the road.
Traffic speed • Reinforces the speed limit directly in
front of the driver.
• Easy to install and relatively
inexpensive
• Only moderately effective in reducing
speeds (brings speed limit to drivers’
attention but does not force or
motivate compliance)
Low ($500 per
location)
Striping, lane definition or narrowing This treatment uses paint to widen parking
or bike lanes, add buffers between traffic
and parking or bike lanes, or widen a painted
median. The purpose is to constrict the width
of the travel lanes, reducing driver comfort
and thus speeds. Paint can help narrow travel
lanes while still allowing flexibility and mobility
for trucks and parking traffic.
Traffic speed • Can be installed quickly
• Easy to remove compared to a
hardscape improvement
• Adding buffers to bike lanes and
parking improves comfort for cyclists
and parking drivers.
• Increased regular maintenance
• Increases resurfacing costs
• Only moderately effective
Low ($0.15 per
linear foot)
High visibility crosswalks High-visibility crosswalks incorporate a striped
pattern that catches motorists’ attention.
Yield lines consisting of rows of triangles may
also be added in advance of crosswalks.
It is City policy to discourage such crosswalks
at mid-block locations (studies have shown
that these devices can give pedestrians a false
sense of security when placed mid-block). In
addition, high visibility crosswalks are to be
used only at locations with curb ramps.
Traffic speed • Increased crosswalk visibility and
motorist awareness
• Indicates preferred crossing locations
to pedestrians
• Can create a false sense of security for
pedestrians
• Increased maintenance costs compared
to regular crosswalks
• Should be well lit
Medium ($2,500
average cost each)

Vertical hardscape Speed humps or cushions Speed humps or speed cushions are asphalt
mounds constructed on the roadway surface,
typically are 3 inches high and 14 feet long.
The distinguishing feature of speed cushions
are cutouts designed to let vehicles with wide
wheel bases pass through without traveling
over the raised surface. However, not all
emergency vehicles are able to take advantage
of this feature.
Traffic speed and volume • Effectively slows vehicles
• Can result in decrease of traffic
volumes
• Slows emergency response times
• Requires advance warning signs
• Increases noise near speed cushion
• Can result in traffic diversion to other
neighborhood streets
• May pose problem for bicyclists
High
(approximately
$10,000-$15,000
each with required
signage)
Speed table/raised crosswalk A speed table or raised crosswalk is a speed
hump with a flat section in the middle and
ramps on the ends. These are sometimes
constructed with brick or other textured
materials on the flat section.
Traffic speed and volume • Improves safety for both vehicles and
pedestrians
• Upgrades to pavement texture can
have positive aesthetic value
• Effective in reducing speeds
• If used, textured materials can be
expensive
• Impact to drainage needs to be
considered
• Textured pavement can increase noise
to adjacent residences

Raised intersection A raised intersection is a flat, raised area
covering an entire intersection with ramps
on an all approaches. The plateau is generally
about 4 inches high. Typically, raised
intersections are finished with textured
pavement.
Traffic speed • Effectively reduces vehicle speeds
• Enhances pedestrian safety
• Can be aesthetically pleasing
• Expensive to construct and maintain
• Requires drainage modifications
• Affects emergency vehicle response
time
• May require bollards around corners
High ($35,000
to $80,000 per
intersection)
Horizontal hardscape Chicanes or lateral shift Chicanes are a series of curb extensions that
alternate from one side of the street to the
other, forming S-shaped curves.
A lateral shift is the construction of curb
extensions into the roadway that creates a
horizontal deflection drivers must negotiate.
Traffic speed • Effective in reducing vehicle speeds
• Can accommodate landscaping and
other amenities
• Street sweeping may need to be done
manually
• Can impact parking and driveway access
• May reduce the number of on-street
parking spaces.
• Increased maintenance
• May create opportunities for head-on
conflicts on narrow streets
• Should not extend into designated
bicycle lanes
High ($10,000
to $100,000,
depending on site
conditions and
design of project)
Curb extension or intersection
bulbout
Extensions at midblock or intersection corners
that narrow a street by extending the sidewalk
or widening the planting strips.
Traffic speed • Effective in reducing vehicle speeds
• Reduces pedestrian crossing width
and increases visibility of pedestrian.
• Opportunity for landscaping.
• Can impact parking and driveway access
• Bicyclists and motor vehicles must share
narrowed travel way
• Requires landscape maintenance at
intersections to preserve adequate sight
distance
• Expensive to install and remove
High ($25,000-
$50,000 or more,
depending on
design of project)
Intersection Control Neighborhood Traffic Circle Neighborhood traffic circles use physical
elements in the center of low volume
intersections to control traffic speeds. Traffic
circles be installed using simple markings
or raised islands, but are best applied in
conjunction with planting that beautify the
street and the surrounding neighborhood.
Careful attention should be paid to the
available lane width and turning radius used
with traffic circles. Traffic circles can be stop
or yield controlled.
Traffic speed; stop sign
compliance
• Increase safety at intersections.
• Requires less space than larger
roundabouts, existing intersections
can be retrofitted more easily
• Can enhance neighborhood aesthetics
• May increase bicycle/automobile
conflicts.
• Can increase emergency vehicle
response time.
• Can restrict large vehicle access (should
avoid bus routes)
• Expensive to install
High ($15,000
for a temporary
traffic circle and
$40,000-$50,000
for a permanent
installation)
Mini-roundabout Similar to a neighborhood traffic circle, a
mini-roundabout uses a raised circular island
to require vehicles to slow down to maneuver
through the intersection.
Mini roundabouts typically are yield controlled
and use painted or raised splitter islands to
angle traffic into the roundabout.
Traffic speed • Effectively reduces vehicle speeds.
• Reduced potential for collisions.
• Increased access for side streets.
• Landscaping opportunity
• Minimal noise impacts
• Can reduce delay and noise at stop-
controlled intersections that do not
meet signal warrants
• Loss of parking.
• Expensive
• Possible decrease in emergency
response times.
• Potential increased conflicts between
bicycles and automobiles
• Potential increased maintenance
• May require additional right-of-way

NEIGHBORHOOD TRAFFIC
MANAGEMENT PROCESS
An overview of the neighborhood traffic management process is shown in Figure 3
and described in more detail below.
STEP 1. PROCESS INITIATION AND PROGRAM
ELIGIBILITY ASSESSMENT
Community members with neighborhood traffic management concerns can initiate the process
by filling out a Traffic Advisory Committee request form, accessible on the City’s website. City staff
will evaluate whether the request is related to neighborhood traffic management (excess speeds
and volumes). If so, City staff will inform the community member that a traffic calming petition is
needed from the affected block for the City to initiate a traffic calming study. If the traffic concern
is other than neighborhood traffic management, it will be considered by the Traffic Advisory
Committee at its next scheduled meeting.
STEP 2. NEIGHBORHOOD TRAFFIC CALMING PETITION
City staff will provide the concerned community member with a traffic calming petition form.
The City will require at least ten signatures of support from residents of the affected block (both
sides facing a street between intersections) to initiate the neighborhood traffic management
process.1 Only one signature per household from community members currently residing at each
street address is necessary.
A signature of support on the traffic calming petition is not a commitment to a specific traffic
calming measure being installed. Rather, the petitions are intended as an indication of community
agreement that a problem exists and that the City should commit resources to addressing the
situation. A copy of the traffic calming petition form may be found in the appendix to this report.
1 Exceptions may be made for very short blocks or those with institutional land uses such as parks or schools.

2120CITY OF SOUTH SAN FRANCISCO
STEP 3. INITIAL ASSESSMENT
Once a completed traffic calming petition has been received, Department of Public Works
staff will conduct an initial assessment of conditions. The assessment will include a field visit,
collection of traffic speed and volume measurements and a review of collision history in the
area. Upon completion of the assessment, City staff will inform the lead contact person from the
traffic calming petition whether the location in question meets criteria for traffic calming. The
relevant criteria are as follows:
• For concerns regarding excess speeds, the criterion is that the 85th percentile speed of all
vehicles in the affected location(s) exceeds the posted speed limit by 7 miles per hour
(mph). For a street with a posted speed limit of 25 mph, for example, 15 percent of the
vehicular traffic would be traveling at or above 32 mph.
• For concerns regarding excess traffic volumes, including suspected “cut-through” traffic
(traffic with neither an origin nor destination within the residential neighborhood bounded
by major arterial streets), the criterion is a minimum of 1,000 vehicles per day. This is
roughly comparable to the daily trip generation expected from 100 single family residences
and is considered a reasonable amount of traffic for a residential street to carry. The 1,000
vehicle-per day criterion has also been used as the standard by several other Bay Area cities.
At least one criterion must be satisfied for the City to proceed with developing a NTM plan for
the affected area. Note that satisfaction of a criterion does not guarantee that a specific traffic
calming measure will be implemented. If traffic calming is found to be warranted, the process
will proceed to the next step. If not, the location will be referred to the Police Department for
targeted enforcement.
STEP 4. PREPARE NEIGHBORHOOD TRAFFIC MANAGEMENT PLAN
At this stage of the process, community members are in agreement that there is a traffic issue
and City staff have confirmed that the magnitude of the problem meets the criteria for traffic
calming. The next step is for the City to prepare a neighborhood traffic calming plan addressing
traffic calming needs for both the location(s) identified in the petition(s)2 and, if appropriate, the
surrounding neighborhood.
In identifying appropriate measures for traffic calming, staff/consultants will assess whether
placing traffic calming devices on one street has the potential to shift traffic to alternative
routes within the neighborhood. In this case, implementing traffic calming measures in just
the location described in the traffic calming petition could simply shift the problem from one
location to another. To avoid this outcome, neighborhood traffic management plans will assess
neighborhoods as a whole. NTM plans may provide for traffic calming devices to be placed
throughout a neighborhood but installation may occur in phases to see whether excess traffic
diversion occurs after the initial placement of devices.
Neighborhood traffic management plans will draw from the toolbox of measures listed in Tables
1 and 2. At a minimum, plans will include Tier 1 measures such as roadway markings and signage.
Tier 2 measures such as speed cushions may also be included based on engineering judgement
and the nature of the traffic issue (speeding, excessive cut-through traffic, or other). The factors
considered in selecting Tier 2 measures include but are not limited to availability of public
right-of-way, volume of pedestrian crossings, presence of bus or bicycle routes, and availability
of funding. Of the Tier 2 measures, speed cushions or humps are the easiest and lowest cost
devices to address speeding issues and will likely be the most frequently recommended traffic
calming device. However, each location will be evaluated on its unique characteristics. Plans will
be prepared in consultation with the Police and Fire Departments to avoid undue impacts on
emergency response times.
Traffic calming devices may be thought of as amenities that aid motorists in obeying traffic
regulations already in place. Streets should already be meeting all applicable design standards
prior to installation of traffic calming devices. If the City identifies a design deficiency during the
preparation of an NTM plan, this issue will be addressed outside the NTM process.
NTM plans will consist of the following: a definition of the study area or neighborhood, a
summary of data collected and traffic conditions, a description of the proposed traffic calming
measures, a map locating traffic calming devices throughout the neighborhood, and conceptual
designs or diagrams as necessary.
2 If the City receives several petitions from the same neighborhood within a short period of time, these will be
grouped together and addressed comprehensively as one project.
CITY OF SOUTH SAN FRANCISCO NEIGHBORHOOD TRAFFIC MANAGEMENT POLICY AND PROCEDURES (DRAFT) | SEPTEMBER 201822 23
STEP 5. PUBLIC OUTREACH
After a draft NTM plan is developed, the community will be informed of the proposed measures.
Every address in the neighborhood covered by the plan will receive an informational flier
summarizing the plan with links to the NTM plan document on the City’s website. Community
members will be provided direct contact information to use in providing feedback.
If the NTM plan is extensive, an optional community meeting will be held so that City staff and
consultants can present the plan and receive feedback in person. Time and location for any
public meetings will be provided by mail and through the City’s social media outlets.
Based on feedback received through the public outreach process, the NTM plan may be
modified to address community concerns. The revised NTM plan will be again circulated to
the community.
To ensure that most neighborhood residents are supportive of any Tier 2 measures (for example,
speed cushions or traffic circles) in a NTM plan, a ballot will be mailed to all affected addresses.3
Affected addresses are defined as any property within 500 feet of a proposed Tier 2 traffic
calming device or intersection modification. A sample ballot form is shown in Appendix B.
Ballots may be returned by mail, dropped off at the Department of Public Works, or scanned and
returned via email within two weeks.
The City will require affirmative support from two thirds of the responses received before
considering implementation of Tier 2 measures. If the two-thirds support is not received, the
City will consider only Tier 1 measures (roadway markings and signage) for implementation.
3 A separate ballot will be mailed to each multifamily unit at the same street address. Nonresident property owners
may also request and submit a ballot.
STEP 6. IMPLEMENTATION
Tier 1 measures can generally be installed relatively quickly, with City maintenance staff handling
measures such as sign installation, for example. Approved and funded Tier 2 measures will be bid
and constructed according to the City’s standard procurement process.
Budget and Prioritization
The City designates an annual budget for traffic-related projects administered by the
Traffic Advisory Committee (TAC). In general, Tier 1 measures proposed in a Neighborhood
Traffic Management Plan will be funded from the annual TAC budget. Tier 1 projects will be
implemented in the order that the traffic calming petitions are received. If the Tier 1 project
funding needs exceed the TAC budget in a given fiscal year, any new traffic calming projects
identified after the budget is exceeded will be placed in a list to be implemented under the next
fiscal year’s budget.
Tier 2 projects proposed in an NTM plan will require approval from the City Council as funding
source(s) must be identified and appropriated. In some cases, a pilot or temporary version of a
Tier 2 measure will be installed and evaluated prior to a permanent installation. Such temporary
or pilot installations can generally be funded from the TAC budget.
STEP 7. FOLLOW UP DATA COLLECTION (OPTIONAL)
In some cases, the City will collect traffic speed and volume data after installation of traffic
calming devices to assess whether traffic calming objectives have been met. If traffic speed or
volume still appears to be a problem, additional traffic calming measures may be considered. A
revised NTM Plan would be presented to the community and affected residents polled before
installation of any additional traffic calming measures.

TRAFFIC CALMING
DEVICE REMOVAL
By developing this NTM policy and procedure, the
City anticipates that traffic calming devices installed
as part of an NTM plan will have the support of the
community and will function as intended. However,
if at some point community members feel that the
devices are not functioning well or otherwise wish
them removed, the procedure would be similar
to the NTM process for installation of traffic
calming measures.
A community member would first file a TAC request
form and then a petition for traffic calming measure
removal. Public outreach and polling of residents of
the neighborhood would take place before removal
of traffic calming devices. As with installation of
traffic calming devices, removal would also require
approval by two thirds of the responding residents.
