Evaluation Overview
The project team developed an evaluation flowchart (see Figure 14) to understand each project’s
effectiveness at meeting three key goals:
1) Reducing vehicle speeds
2) Improving safety and comfort for street users
3) Ease of maintenance
In 2020, Boulder City Council allocated $250,000 to the Transportation and Mobility (T&M) Department
to support the city’s goal of achieving zero serious injury and fatal traffic deaths, known as Vision Zero.
T&M staff programmed a portion of this funding for the Vision Zero Innovation Program (VZIP), to
speed delivery of projects that would support the city’s Vision Zero goal. During 2020 and 2021, T&M
staff implemented VZIP quick-build projects on six corridors and at six intersections across the city,
with the goal of increasing safety for cyclists and pedestrians (a map of VZIP projects is shown in
Figure 1). VZIP’s cost-effective installations were intended to accelerate progress toward creating more
comfortable and safer streets, by supporting neighborhood petitions submitted through the former
Neighborhood Speed Management Program (NSMP) and advancing areas identified by community
members as locations of concern.
Vision Zero Innovation Program (VZIP) Overview

concerns with limited resources. The program
implemented a variety of treatment types,
including:
• Chicane (1 location)
• Curb extensions (17 locations)
• Pavement art with curb extensions
(3 locations)
• Hardened centerline (1 location)
• Median islands (3 locations)
• Pinch points (4 locations)
• Traffic circle (1 location)

To understand whether projects reduced vehicle speeds, the project team collected before and after
speed and volume data near VZIP project locations, and calculated average speeds, 85th percentile
speeds, the percent of vehicles traveling greater than or equal to 25 mph, and the percent of vehicles
traveling greater than or equal to 30 mph. The evaluation framework also considered whether the
average speed after installation was within 3 mph of the speed limit.
To understand whether projects improved safety and comfort for street users, the project team
reviewed community feedback submitted via a Formstack questionnaire posted on the project
webpage as well as calls and emails to city staff. Signs were also placed on-site near VZIP installations
to encourage community members to provide feedback. Over 300 community responses were
submitted during the outreach period prior to and following installation.
The project team consulted with the City of Boulder Fire Department and Transportation Maintenance
staff, including staff in charge of street sweeping and snow removal, to understand whether projects
are easy to maintain. The evaluation recommendations considered whether each VZIP installation
had a significant impact on the ability of these personnel to conduct emergency and maintenance
operations. The evaluation recommendations also considered whether the project was located on a
Neighborhood GreenStreet or bike route.
The VZIP projects derived from the NSMP were developed with a target design speed of 20 mph,
requiring consideration of on-street parking zones, drainage, and the locations of fire hydrants,
crosswalks, curb ramps, and driveways/curb cuts. Treatment types were determined through a balance
of these considerations, as well as coordination with emergency and maintenance staff.
Project Recommendations
Given the ability of each project to meet the three goals outlined above, the project team determined
whether to keep the installation in place, modify the installation, or remove it. For installations
recommended for removal, staff may consider another project in the long-term or in conjunction with
work planned through the Core Arterial Network (CAN). Table 1 details evaluation recommendations
at each VZIP location.

The VZIP intends to create slower and more comfortable streets for active users through a targeted
application of speed-reducing and pedestrian safety treatments. Grounded in the city’s 2014 adoption
of Vision Zero and in support of the 2019 Transportation Master Plan (TMP), the VZIP takes a data-
driven approach to addressing speeding, which contributed to one out of every three serious crashes
within the city between 2018-2020. The “20 Is Plenty” ordinance adopted in Summer 2020 aligns with
these goals and supports the policy of reducing vehicle speeds in residential areas to mitigate the risk
of serious injury and fatal crashes.
CREATE SLOWER AND MORE COMFORTABLE STREETS
The City of Boulder’s Vision Zero Innovation Program (VZIP) is intended to deliver quick-build,
innovative, and community-responsive projects to enhance bicycle and pedestrian safety. VZIP is one of
several city programs aimed at achieving Boulder’s Vision Zero goal of eliminating fatalities and serious
injuries caused by traffic crashes. VZIP projects were installed at locations identified either through
safety analyses such as the 2019 Safe Streets Report, sourced from the former Neighborhood Speed
Management Program (NSMP) community-driven petitions, or via staff’s community engagement
efforts specific to the VZIP in 2021.
VZIP projects that originated from the NSMP were previously evaluated by staff and included on the
NSMP Complex Project list per review and recommendation by the Transportation Advisory Board
(TAB). The “20 is Plenty” ordinance lowered speed limits on local, residential streets from 25 mph to
20 mph, which effectively widened the gap between the speed limit and the observed highest 85th
percentile speeds used to qualify a street for the NSMP. These circumstances created a greater need
to address speeds on six unfunded NSMP Complex Project List streets and so led to prioritizing these
locations for VZIP projects.
The VZIP goals are to slow vehicle speeds for more comfortable streets, support ongoing Vision Zero
efforts, test new and innovative traffic calming treatments, and implement measures in a cost-effective
and efficient manner. This report details how each project advances these goals.
Purpose of the Vision Zero Innovation Program
A. Introduction
SUPPORT AND INFORM CONCURRENT MULTIMODAL PROGRAMS
Another objective of the VZIP is to support related city capital improvement programs, such as
the Low Stress Walk and Bike Network Plan, Neighborhood Greenstreets, Pavement Management
Program Mobility Enhancements, Pedestrian Crossings, and the Core Arterial Network, informing the
applicability of innovative treatment types for future capital improvement projects. One such program
is the NSMP, which at the time of VZIP’s inception had a demand exceeding the program’s usual
$250,000 annual budget. Since the NSMP’s inception in 2017, only one or two complex projects were
planned or implemented annually. Complex projects are differentiated from simple projects due to
their location on emergency response corridors, requiring treatment modifications to accommodate
and reduce delay for emergency vehicles. Bolstered by community support from the NSMP, VZIP
5
treatments were delivered on a total of six NSMP Complex Project corridors (Aurora Avenue, Glenwood
Drive, Grinnell Avenue, Mohawk Drive, Palo Parkway, and Quince Avenue) as an interim solution to
address speeding concerns and speed limit reductions originating from the “20 Is Plenty” ordinance.
The Low-Stress Walk and Bike Network Plan envisions a safe and low-stress network of multimodal
routes complemented by wayfinding and prioritized connections to key destinations. Within this
network-level effort is the development of Neighborhood GreenStreets, which are low-traffic streets
designated by pavement markings, signage, and crossing treatments to foster comfortable and safer
travel environments for all ages and abilities. Most of the streets that received VZIP treatments
are on planned GreenStreets. The Core Arterial Network (CAN) aims to reduce severe crashes on
13 segments of Boulder’s arterials through the installation of protected bicycle lanes, intersection
enhancements, pedestrian facilities, and transit facility upgrades over the next several years. VZIP
projects may inform short-term treatments such as hardened centerlines or curb extensions on the
CAN, or can be used to support connections to CAN corridors.
TEST INNOVATIVE HORIZONTAL TRAFFIC CALMING TREATMENTS
The VZIP is an opportunity to assess traffic calming treatments that are new to the city of Boulder,
including a speed kidney which may be the first of its kind in North America. It is also an opportunity
to pilot traffic calming treatments to inform permanent capital projects. The program focused on
horizontal speed deflection treatments including chicanes, curb extensions, hardened centerlines,
median islands, pinch points, and traffic circles, since temporary vertical treatments may not be
compatible with snow removal during winter storms. Horizontal treatments are intended to slow
vehicles by either visually narrowing the roadway or by causing drivers to change their travel path to
navigate around the devices. Horizontal treatments may not result in significant reductions in traffic
volumes and may be less effective than vertical deflection devices like speed humps in reducing
vehicle speeds. However, the speed kidney is a traffic calming device that combines both horizontal
and vertical deflection because it gives drivers the option to travel through curvilinear cutouts or over
the component humps, and so it was included in the VZIP.
IMPLEMENT HORIZONTAL TRAFFIC CALMING TREATMENTS QUICKLY AND
AFFORDABLY
A further benefit of the VZIP is its capacity to deliver horizontal traffic calming treatments quickly
and affordably. Typical transportation projects may have lengthy implementation timelines due to the
sequencing of design, approvals, and funding. To help achieve Vision Zero goals, it is important for city
staff to deliver project improvements that are responsive to community needs and expectations. The
low-cost, quick-build nature of these treatments allows for flexibility and modification, given changing
conditions, data collection results, and feedback from internal stakeholders and the community.
Furthermore, the COVID-19 pandemic’s impact on the City of Boulder’s budget prompted the need
to work with reduced funding. Though most treatments consist of paint and plastic post (delineator)
installations, city staff collaborated with local artists where feasible to beautify the installations and
reflect community character.

Purpose of this Evaluation Report
The purpose of this report is to develop a framework to evaluate the effectiveness of treatments
installed in 2020 and 2021, and to recommend where to keep, modify, or remove VZIP treatments based
on consideration of objective and subjective evaluation criteria. This report also provides information
to staff on the general effectiveness of specific treatments installed through the VZIP, and can be
used as guidance for future projects where speeding or bicycle and pedestrian safety are concerns.
EVALUATE VZIP TREATMENTS AND OUTLINE PROCESSES FOR FUTURE
EVALUATIONS
Many factors influenced the effectiveness of VZIP treatments installed in more than two dozen
locations across the city, including device spacing, street width, neighborhood traffic volumes,
the frequency of driveways or curb cuts, and more. This report provides an evaluation of these
installations and recommendations for their continued use. Additionally, this report provides a
barometer for future evaluations by establishing a process to determine the effectiveness of VZIP-
type treatments through the analysis of various measures of effectiveness. The evaluation results
will help guide when, where, and how particular treatments are chosen and installed within the city.
PROPOSE TREATMENT EVALUATIONS AND RECOMMENDATIONS
Based on the evaluation results, staff will be able to evaluate whether treatments should be kept,
modified to be more effective, or removed entirely. Additional recommendations may reveal
maintenance considerations and design modifications for future materials selection, including the
impact on street sweeping and snow plowing operations.

Traffic calming is an important component of multimodal transportation networks because it can
help cyclists and pedestrians feel safer and more comfortable, and can mitigate the severity of
potential crashes by reducing vehicle speeds, which is a core tenet of Vision Zero. The Institute of
Transportation Engineers (ITE) defines traffic calming as:
“The combination of mainly physical measures that reduce the negative effects of motor
vehicle use, alter driver behavior, and improve conditions for non-motorized street users.”1
There are both safety and quality of life benefits afforded by traffic calming; in addition to speed
reduction, traffic calming devices can also increase sight distances and improve motorist awareness
of pedestrians and cyclists. Targeted traffic calming can support neighborhood-based bikeways
connected to separated facilities, or efforts to prioritize non-vehicular street users through “Shared
Street” installations or closures. Traffic calmed neighborhood streets also support community
expectations for these places: that they are safe for children and pets, and free from reckless drivers.
CRASH MODIFICATION FACTORS (CMFS)
According to the FHWA, a Crash Modification Factor (CMF) “…is a multiplicative factor used to
compute the expected number of crashes after implementing a given countermeasure at a specific
site.”2 These estimates can be helpful for calculating cost/benefit ratios and when deciding between
appropriate treatment types. Countermeasures with CMFs under 1 demonstrate a crash reducing
effect (i.e., a countermeasure with a CMF of 0.70 would estimate a 30-percent crash reduction).
The CMFs for various treatment types are detailed below.
• For the countermeasure “median treatment for ped/bike safety” (in the CMF Clearinghouse3):
○Three of the four CMFs listed in the Clearinghouse demonstrate a decrease in crashes,
including a Crash Reduction Factor (CRF) of 86-percent for fatal pedestrians and cyclist
related crashes (0.14 CMF) and a CRF of 14-percent (0.86 CMF) for all crashes, not exclusive to
pedestrians and cyclists.
• For the countermeasure “convert two-way stop-controlled intersection to roundabout” for 1-2
lane roads in the Suburban area type (NCHRP Applying Roundabouts in the United States):
○All six of the CMFs listed in the Clearinghouse demonstrated a decrease in crashes and the
CMFs ranged from 0.22-0.81, or a reduction factor of 19-percent to 78-percent.

Guidance
Safety Benefits of Traffic Calming
8
The 2022 Vision Zero Boulder: Safe Streets Report identified crash types of concern, including
crashes involving a left turn (34-percent of severe crashes), speeding (32-percent of severe crashes),
impairment (11-percent of severe crashes), and distraction (7-percent of severe crashes). Targeting
engineering modifications at locations of concern based on identified crash types most effectively
addresses safety needs. For example, the VZIP installed a hardened centerline on the east leg of the
intersection at Baseline Road and Mohawk Drive, which was one of two locations in the city with
the highest number of severe left-turn crashes between 2018 and 2020 (including a fatal crash). The
device was installed to reduce vehicular turning radii, reduce speeds, and increase visibility between
drivers and crosswalk users.
Aside from the Baseline Road and Mohawk Drive location, the VZIP project locations do not specifically
address crash trends. It is important to note that this evaluation did not include conducting crash
analyses given the lack of documented crash trends in project areas. However, during the design
process the project team considered mitigating measures to reduce any potential crash risk and
severity, such as improved sight lines, material durability, and reduced corner-radii for vehicle
turning paths. The inclusion of CMF information in this section of the report is meant as guidance
for consideration in future projects, especially those that are located on higher volume arterials like
Baseline Road.
RELATIONSHIP BETWEEN SPEED AND CRASH SEVERITY
Lowering vehicle speeds is highly effective in decreasing the severity of crashes involving active
users, should they occur. According to ITE4, the chance of a fatal vehicle-pedestrian crash increases
from 10-percent at a vehicle speed of 20 mph to 80-percent at 40 mph. The 2022 Safe Streets Report
found that speeding is a contributing factor in one of every three severe crashes in the city. While
these crashes occurred almost exclusively on arterials, it is important to consider the relationship
between speed and crash severity when addressing speeding concerns throughout the city, including
on local and collector streets.
INCREASE VISIBILITY OF ACTIVE USERS AND IMPROVE SIGHT DISTANCES
Traffic calming treatments can enhance pedestrian and cyclist safety by increasing sight distances
at corners (also called daylighting) and enhancing the visibility of crossing locations, both at
intersections and mid-block. The Burlington Public Works Quick Build Design + Materials Standards5
guide recommends designing treatments to improve sight distance triangles and maximize visibility.
Treatments such as curb extensions, median islands, and street murals can assist with delineating
sight triangles for vehicles while reducing crossing distances and, in the case of street art, provide
beautification. Cities across the country have had success putting these daylighted areas to beneficial
use for active modes, such as Hoboken, New Jersey’s targeted approach to daylighting at intersections
which appears to have contributed to the city’s lack of traffic fatalities (0 since 2018).6

Speed Reduction by Design Best Practices
This section will review best practices for achieving speed reductions through design, including design
guidance for device spacing to maximize traffic calming effectiveness. Traffic calming project design
is dependent on various local conditions, including street width, driveway/curb cut spacing, presence
or lack of pedestrian facilities, and drainage considerations, and can be influenced by concerns from
property owners, residents, or emergency and maintenance staff. In Boulder, traffic calming projects
have historically been designed starting with guidance from ITE and the sources below, and adjusted
for local considerations. Project design, including device width, height, and spacing on project streets,
should continue to be determined with context sensitivity in mind.
SPACING OF DEVICES TO ACHIEVE DESIRED VEHICLE SPEEDS
• Spacing observations for plastic delineators
○The Tactical Urbanist’s Guide recommends placing flex posts every 8-10 feet within curb
extensions.7
• Spacing observations for pinch points
○The National Association of City Transportation Officials (NACTO)’s guidance recommends
that pinch points reduce the two-way travel path to less than 18 feet, with 12 feet preferred.8
• Spacing observations for median islands
○Pennsylvania’s Traffic Calming Handbook advises that medians be 6-8 feet wide and 12-20 feet
in length to maximize user comfort.9
• Spacing observations for traffic circles
○The NACTO Urban Street Design Guide recommends traffic circles provide approximately 15
feet of clearance from the widest point of the circle to the nearby corners.8
○Pennsylvania’s Traffic Calming Handbook advises that a series of traffic circles are most
effective at reducing speeds.9
VZIP TREATMENT TYPES
Chicane
Treatment Details: Chicanes are created by an offset paring or series of curb extensions, which require
drivers to slow down to navigate an S-shaped travel path. The chicane installed through the VZIP is
designed for one-way traffic; it is too narrow for two vehicles to proceed side-by-side and therefore
requires street users to yield to one another.
Impact: According to Pennsylvania’s Traffic Calming Handbook, chicanes have the potential to reduce
vehicle speeds within the treatment itself by 5-13 mph and by 1-6 mph for vehicles approaching or

departing the device.10 The Federal Highway Administration (FHWA)’s Engineering Speed Management
Countermeasures Table estimates a speed reduction of 6-9 mph based on case studies on two-lane
streets in rural communities, a 16-percent reduction in the 85th percentile speed on an urban road,
and a 29-percent reduction on other roads.10
Curb Extensions
Treatment Details: Curb extensions, which are also called neck downs or bulb-outs, are typically
installed at intersections to provide an extension of the sidewalk further into the roadway, reducing
the crossing distance for active users and narrowing travel lanes to slow vehicles. Vehicles making
right turns can also be slowed by narrowed lanes and tightened turning radii. Mid-block installations
may be beneficial at locations of high pedestrian traffic, such as near schools or multiuse paths.
Impact: According to Pennsylvania’s Traffic Calming Handbook, curb extensions reduce speeds by 1-2
mph on average and up to 5 mph if lane widths are significantly narrowed (to between 18-20 feet total,
which is most applicable on low volume streets).11
Hardened Centerline
Treatment Details: Hardened centerlines are small rubber barriers next to crosswalks that also have
raised vertical elements and require people driving to make slower, squarer left-hand turns.12
Impact: According to the City of Kingston, Ontario’s Traffic Calming Guidelines13, hardened centerline
treatments have the potential to reduce speeds by up to 5 km/h (roughly 3 mph).
Median Island
Treatment Details: Median islands provide a center refuge area for pedestrians and cyclists to wait for
a gap in vehicle traffic before completing their crossing.
Impact: According to Pennsylvania’s Traffic Calming Handbook, the most prevalent speed reductions
that were observed following the installation of median islands were 2-3 mph, though the range was up
to 5 mph. Speed reductions are greater when lanes are narrowed in conjunction with median islands,
or when there is more horizontal deflection in the vehicle travel path.11
Pinch Point
Treatment Details: Pinch points (also called chokers) are mid-block curb extensions that narrow travel
lanes. Pinch points can narrow a street to a one lane roadway that is too narrow for two vehicles
to proceed side-by-side, which creates yielding conditions, or can maintain two-way traffic with two
lanes. In the case of two-way pinch points, drivers may feel less comfortable passing oncoming traffic,
resulting in slower speeds. Both types of pinch points were installed though the VZIP. Yield signs may

be placed to govern safe travel patterns. Pinch points may also be called curb extensions in some
contexts.
Impact: The FHWA estimates a 1-4 mph speed reduction following pinch point installation. 14
Speed Kidney
Treatment Details: A speed kidney features a grouping of three speed humps, with an oval-shaped
hump straddling the center of the road and one “kidney” shaped hump on each side within the travel
lanes aligning with the center oval’s curvature.
Impact: According to the City of Kingston, Ontario’s Traffic Calming Guidelines, speed kidneys may
result in up to a 5 km/h (roughly 3 mph) reduction in speeds.15
Traffic Circle
Treatment Details: Neighborhood traffic circles are installed at unsignalized intersections and typically
consist of raised or delineated islands which traffic must negotiate in a circular manner. Yield signs
are placed within the circles to govern safe travel patterns.
Impact: According to Pennsylvania’s Traffic Calming Handbook, traffic circles have the potential to
reduce speeds by 4-6 mph.16
Pros and Cons of Quick Build Horizontal Treatments
The major benefits and critiques of the VZIP’s quick-build treatments are detailed below and offer
lessons learned for future modifications to quick-build traffic calming projects.
LIFE CYCLE OF QUICK BUILD VERSUS PERMANENT TREATMENTS
When determining the costs and benefits of quick build treatments versus permanent installations, it
is important to consider the life cycle implications of materials like paint and plastic posts (delineators)
which are intended to be interim in nature versus longer-term materials like concrete.
PROS
There are several pros to quick build treatments, namely:
• Opportunity for in-house design and installation or with targeted help from vendors. The
design phase of a typical project may involve a series of iterations, ensuring design standards
and budget goals are met. Hiring outside consultants may be beneficial to support city staff,
but can increase costs and may lengthen the timeframe between design and installation. The
VZIP employed targeted design help from consultants but relied on T&M staff to implement
treatments.

public/pubsforms/Publications/PUB%20383.pdf
12
• An accelerated installation timeline. Given favorable weather in the spring/summer, VZIP
treatments were able to be installed very rapidly (in some cases with multiple treatments
installed in a single day). Such a task would have been infeasible for a typical series of capital
improvements projects (which are usually built in concrete).
• Greatly reduced cost. The quick build (“paint and post”) style delivery of VZIP treatments
resulted in significant cost reductions compared to concrete capital projects. In general, quick
build treatments each cost in the thousands versus the tens to hundred thousand dollar cost
of capital improvement projects, that might include project elements such as speed cushions/
humps, concrete curb extensions, median islands or traffic circles.
• Ability to modify designs flexibly and creatively. VZIP treatments were iterative in their design
and installation. Staff was able to monitor conditions at the treatment sites and efficiently adjust
treatment elements when warranted.
• Ease of project removal should a maintenance/operational concern or data finding warrant it.
A further benefit of the quick build nature of VZIP treatments is the ability to remove treatment
elements as needed. The removal costs and timeframe for typical capital improvement projects
would far exceed the flexibility of paint and post modifications or removals.
CONS
There are also several cons to consider with quick build treatments, namely:
• Reduced lifecycle. Quick build treatments are less durable than their concrete counterparts,
with a reduced ability to withstand serious impacts and an increased chance of damage to
device materials. Figures from the Denver Department of Transportation and Infrastructure
(DOTI)’s Vertical Elements Study17 estimated that typical concrete elements have a 50-year life
cycle, with quick build elements having closer to a 25-year life cycle. Quick build elements are
vertical and constructed of low-cost materials; they include flex post bulb-outs, median refuge
islands, rubber corner wedges, and rubberized traffic circles. Vertical elements would be replaced
every 10 years during a street’s mill/overlay cycle (assuming damage did not warrant prior
replacement).
• Appearance. Following VZIP treatment installation, community members commented that
the treatments appeared ugly, unfinished, or akin to a construction zone. Though a handful of
treatments were paired with artistic additions, this was not possible for all treatment types or
locations due to budgetary restrictions, installation timelines, and maintenance concerns.
• Maintenance concerns. As noted above, though the lifecycle of quick build treatment types
varies, additional maintenance may be required when compared to concrete installations. T&M
staff anticipated snowplow blade movements and emergency vehicle response clearance as
concerns during design, acknowledging that in real-world conditions durability may vary.

Design Considerations
To maximize the effectiveness of traffic calming treatments, it is important to analyze the roadway
context and review impacts to essential maintenance operations like snow removal and street
sweeping, as well as potential delays to emergency response.
CONTEXT CONSIDERATIONS
When considering the most appropriate traffic calming treatment types for a given street, roadway
width should be considered given its influence on vehicle speeds. Street width is also important to
determine whether various treatments will fit within the given curb-to-curb space.
Adjacent land uses, whether residential, commercial, industrial, or a combination of these, can
influence the effectiveness of different treatment types. Design should be appropriate for the level
of vehicle access needed and whether traffic calming devices may impede vehicle types (e.g., on
emergency routes or in very dense neighborhoods). For example, on corridors with high truck traffic
or frequent buses, chicanes may not be appropriate given the roadway geometric needs of these
vehicles for navigating the treatment.
The presence and density of on street parking can impact project selection and installation,
discussions regarding parking removal or clear space surrounding an installation. Some devices may
be more appropriate with on-street parking given available street space, depending on the street
context. Where off-street parking is limited, it may make more sense to select traffic calming devices
that do not significantly reduce on-street parking availability.
Furthermore, the presence of pedestrian facilities like sidewalks and crosswalks can influence design
considerations. For example, in areas where no sidewalks are present, designs must consider where
pedestrians will navigate traffic calming on the street. Consideration of multimodal street users
means identifying where different modes may overlap, like around and within pinch points.
IMPACT TO MAINTENANCE AND SNOW REMOVAL OPERATIONS
When first determining the applicability of various quick build improvements, it is important that
maintenance and snow removal teams are included in the design process as design decisions should
be made that do not impede maintenance activities and equipment. Potential treatment types may
be eliminated based on concerns regarding snow removal operations or street sweeping, such as
armadillos (small, elliptical shaped bumps used to create physical delineation), which can prove
challenging for drivers to see and avoid during heavy snow or debris accumulation.
In Boulder, community concerns arose prior to the first snow season following the installation of VZIP
treatments. T&M staff worked with the City Attorney’s Office to clarify snow clearing obligations for
curb extensions adjacent to sidewalks, including property owner responsibilities to clear five-foot
paths on curb ramps and extensions within 24 hours after snow stops falling. The 2021 - 2022 snow
season demonstrated that minor adjustments would benefit plowing operations proximate to VZIP
installations. Recommendations in this report reflect observations from the 2021 - 2022 snow season
as well as consider feedback from property owners who may be responsible for a level of maintenance
around VZIP installations and discussions with maintenance staff.
14
IMPACT TO EMERGENCY RESPONSE
Prioritizing emergency access (for fire, police, and other emergency response personnel) remains
a critical factor when designing traffic calming projects. It is important to discuss turning radii and
lane width requirements with fire and police departments to ensure compatibility with emergency
operations. For example, according to Pennsylvania’s Traffic Calming Handbook18 traffic circles may
incur a delay anywhere from 1-11 seconds per circle, with most delays in the 5-8 second range. A good
starting point for design discussions could include navigation expectations and a determination of
whether to avoid particular devices on certain emergency response corridors.
There is precedent for close coordination in the development of traffic calming projects in Boulder
through the NSMP Complex Projects design process, where treatments (such as speed cushions)
are designed with accommodations for emergency vehicles like fire trucks. A similar coordination
process with first responders was used during the design of VZIP projects.
Data Driven Analysis
Below is a summary of the data analysis methodology for this evaluation report, with an overview of
findings specific to the different treatments installed through the VZIP.
INTERIM TREATMENT EVALUATION PROCESS
The evaluation process for Boulder’s VZIP treatments included gathering before and after data based
on the treatment type and project purpose or intent (e.g., traffic calming, slower turning speeds,
crossing comfort, etc.). Data collection gathered vehicle speeds and volumes and pedestrian counts,
while analysis produced metrics like average speeds, 50th and 85th percentile speeds, the number
of speeding vehicles (going either greater than 5 mph or greater than 10 mph over the speed limit),
average daily traffic volumes, peak hour turning movement counts, and additional, modal-specific
data such as pedestrian crossing volumes. The overarching goal of this evaluation is to determine
whether the installed treatments achieved the desired conditions (i.e., a reduction in average speed
or reduction in the number of high-end speeding vehicles). Specific data-driven results can be found
in Appendix A.
BEST PRACTICES FOR DATA COLLECTION
Effective before and after data collection studies attempt to ensure similar conditions for both
collection timeframes. Key factors considered in data collection for this evaluation study include:
• Weather (i.e., collecting before and after data in similar weather months)
• Time of day (i.e., collecting before and after data in the same part of the day)
• Days of week (i.e., collecting before and after data during the same three-day period)
• Seasonal conditions at location (i.e., collecting before and after data while school is in session)
• Temporary changes at location (i.e., collecting data when there is not construction nearby, under
normal operating conditions)• Allowance for conditions to normalize (i.e., it is best not to collect after data until at least 6
months post-project implementation).

DATA SUMMARIES
Chicanes
A chicane was installed on Quince Avenue west of 19th Street (and paired with pinch points and curb
extensions). Before and after speed studies near the chicane demonstrate a 10-percent reduction
in the average speed (from 22 mph to 20 mph) and 8-percent reduction in the 85th percentile speed
(from 26 mph to 24 mph). There are noteworthy reductions in vehicles traveling at 30 mph or higher (a
71-percent reduction) and in vehicles traveling at 25 mph or higher (a 64-percent reduction).
Curb Extensions
Curb extensions were installed in 11 locations and featured an arrangement of 36-inch-tall plastic
delineators (“posts”) with bolted bases (placed 7-15 feet apart). Curb extensions were the most widely
installed traffic calming element placed on corridors which also received other treatments, including
marked crosswalks/crossing treatments, median islands, traffic circles, and pinch points. At 26th
Street and Spruce Street, Grove Street and 17th Street, and Grove Street and 18th Street, artistic
treatments were painted within the delineator-protected space.
Before and after speed studies near curb extensions demonstrate an average reduction in speeds
of 3-percent. The average 85th percentile speed reduction proximate to curb extension locations is
4-percent. The average reduction in vehicles traveling at 30 mph or higher and at 25 mph or higher is
similar at just under 30-percent reduction.
The most effective VZIP curb extension location in reducing vehicle speeds is Aurora Avenue at 35th
Street, which also has a traffic circle. This location saw a 14-percent reduction in average speed,
16-percent reduction in the 85th percentile speed, 94-percent reduction in vehicles traveling at 30
mph or higher, and 77-percent reduction in vehicles traveling at 25 mph or higher.
Hardened Centerline
A hardened centerline consisting of a rubber speed bump and a traffic separator curb with vertical
panels was installed on the east leg of the intersection of Baseline Road at Mohawk Drive. The before
and after studies conducted near the hardened centerline treatment evaluated vehicle turning paths
to observe whether vehicles crossed after or at/ahead of the median. For those vehicles making a
southbound left turn movement from Mohawk Drive onto Baseline Road (eastbound), 23-percent
crossed after the median before project installation and 91-percent did after project installation. The
hardened centerline appears to improve vehicle and pedestrian interactions by increasing visibility
between turning drivers and pedestrians in the crosswalk. The hardened centerline prevents motorists
from driving over a larger section of the crosswalk prior to completing the left turn.
Additionally, 15-percent of vehicles making a U-turn on Baseline Road (westbound) crossed after
the median before project installation and 36-percent did after project installation. Though not as
significant of an improvement for this vehicle movement, there is still a measurable safety benefit to
the corrected vehicle path.
16
Median Island
Median islands were installed at two locations as a standalone treatment. At another two
locations, median islands were paired with additional treatments, including curb extensions and
pinch points. Before and after studies on Palo Parkway near Palisade Drive, which was one of the
locations with a standalone median island, demonstrated no effectiveness in reducing speeds
with a slight increase in overall recorded speeds.
However, before and after speed studies on Grinnell Avenue west of Knox Drive, the other
standalone median island location, showed an 18-percent reduction in the 85th percentile speed,
a 97-percent reduction in vehicles traveling at 30 mph or higher, and 94-percent reduction in
vehicles traveling at 25 mph or higher. Generally, the width of the median treatment and the street
conditions on Grinnell Avenue (street width, on-street parking occupancy) appear to influence
greater horizontal deflection on Grinnell than at other locations.
At Aurora Avenue near 37th Street where a median island was paired with curb extensions, before
and after speed studies demonstrate a 6-percent reduction in the 85th percentile speed and a
44-percent reduction in vehicles traveling at 30 mph or higher. Conversely, on Mohawk Drive before
and after speed studies demonstrate a 5-percent increase in the 85th percentile speed as well as
in increase in the number of vehicles traveling at 30 mph or higher from 4-percent to 9-percent.
Pinch Points
Pinch points were installed at five locations and paired with other corridor treatments including
curb extensions and median islands. Before and after speed studies where pinch points were
installed demonstrated up to a 9-percent reduction in average speed and 85th percentile speed.
Studies conducted at locations where a pinch point was installed did reduce the number of top
speeders significantly, with the greatest reduction of 70-percent on Quince Avenue.
Speed Kidney
A speed kidney was installed on Cherry Avenue near 9th Street, potentially the first installation
of the treatment in North America. Before and after speed studies at this location demonstrated
a 12-percent reduction in average speed and 17-percent reduction in 85th percentile speed. The
reduction in higher end speeders was more significant, with a 98-percent reduction in vehicles
traveling at 30 mph or higher and 90-percent reduction in vehicles traveling at 25 mph or higher.
Traffic Circle
A traffic circle was installed on Aurora Avenue at 35th Street. Before and after speed studies at this
location demonstrated a 14-percent reduction in average speed and 16-percent reduction in 85th
percentile speed. The reduction in higher end speeders was more significant, with a 94-percent
reduction in vehicles traveling at 30 mph or higher and 77-percent reduction in vehicles traveling
at 25 mph or higher.

D. Lessons Learned and Guidance
for Future Treatments
Lessons Learned
The VZIP was intended to bring innovative, quick-build improvements to Boulder streets to enhance
pedestrian and cyclist safety and comfort. The nimble nature of project installations allowed for
adjustments as needed post installation. Usual challenges were factored into the VZIP Project
Evaluation Flowchart (Figure 14) and provided lessons learned for the future applicability of installing
these treatments elsewhere in the city.
POST-INSTALLATION CHANGES TO TREATMENTS
Chicane (Quince Avenue)
After monitoring community feedback and considering appropriate changes, staff determined that a
few modifications were needed to address concerns that included:
• Motorists feeling constrained to the right of the approach island
• Motorists parking in the area to the right of the approach island
• A lack of clarity that cyclists have the option to take the lane or stay to the right of the island
• Pedestrians feeling “pinched” and vulnerable when walking between approach islands due to
sharing the space with vehicles
• Fire Department concerns about the median posts
Design changes included:
• Adjusting the location of the “No Parking Any Time” signs to more clearly convey that the space
to the right of the approach islands is not for vehicle parking
• Installing green-backed bike lane symbol markings in the area to the right of the approach
islands
• Removing yellow delineators and mini “Keep Right” signs on the painted median island
• Ultimately removing the chicane and replacing it with a pinch point. Similar to the pinch point
west of 17th Street, it is designed with a 12-foot, bi-directional travel lane at the center of the
right-of-way bordered by a paint and post treatment. People driving must slow down and yield
to oncoming road users through the 12-foot lane. Flexible posts will be placed to provide space
separated from vehicles for people walking and biking through the pinch point. East and west of
the pinch point, Quince will remain two shared travel lanes for people walking, biking, and driving.
The central median removal may impact the traffic calming potential of this treatment, though no
data has been collected to determine this.
23
WHAT HAS WORKED WELL
Partnerships with Local Artists
At three VZIP curb extension installations (26th Street and Spruce Street, Grove Street and 17th Street,
and Grove Street and 18th Street) pavement murals were painted within the bollard-protected space.
Community members expressed support for the neighborhood beautification and local artists were
given an opportunity to promote their skills. While these works of art are popular with community
members, longevity and maintenance should be considered before installation.
Reducing High End Speeds at a Low Cost
After installation, data at two VZIP project locations demonstrated a 90-percent or more reduction
in high end speeders (those traveling at 30 mph or more): the traffic circle with curb extensions on
Aurora Avenue at 35th Street and speed kidney at Cherry Avenue near 9th Street. At two additional
project locations (the combination of treatments on Quince Avenue west of 19th Street (chicane,
pinch points, and curb extensions) and the pinch point on Quince Avenue west of 15th Street), a still-
significant 70-percent reduction in high end speeders was achieved.
CHALLENGES & CONSIDERATIONS
Emergency, Transit and Maintenance Vehicle Design
Emergency, transit, and maintenance vehicles (such as street sweepers and snow plows) require
tailored design considerations compared to a typical personal vehicle. Though project staff made
every attempt to design treatments to accommodate these priority vehicles, issues did arise in the
field, like with the traffic circle on Aurora Avenue which required tweaks to ensure emergency and
maintenance vehicle access was not hindered.
Effectiveness versus Public Perception
In order for traffic calming measures to be effective, typical, unrestrained driving patterns need to
be modified through physical and visual modifications to the street. These modifications inherently
require additional attention in navigating traffic calmed streets (such as the yielding conditions at
a chicane or a reduction in turning radius at curb extensions). Modifying the typical, unrestrained
movements may feel bothersome and challenging to community members. Such changes often
garnered negative public feedback.
Parking Occupancy and Access Considerations
The project team attempted to minimize impacts to parking, but the removal of parking was required
to allow room for some VZIP installations. In some cases, curbside space near intersections that was
previously used for parking was replaced with curb extensions which were intended to improve sight
distances and visibility. Though not always indicated by a sign, these spaces are technically illegal
to park within due to their proximity to the intersection (the Boulder Revised Code [7-6-13] prohibits
parking within 30-feet of a stop sign, 20-feet of an intersection or crosswalk, and 5-feet of a fire
hydrant). Furthermore, the chicane installation demonstrated the importance of driveway spacing
constraints when considering treatment installation.
24
Though concerns regarding parking constraints or removal of spots to accommodate VZIP treatments
arose for nearly every corridor, a few in particular (Glenwood Drive, Aurora Avenue, Quince Avenue,
and Mohawk Drive) spurred the most comments. Approximately 20 spots were removed on Glenwood
Drive between Folsom Street and 30th Street (0.5 miles) and 12 spots on Aurora Avenue between 35th
Street and Mohawk Drive (0.4 miles).
Of the 318 recorded comments, about 15-percent (46) mentioned parking. A few comments were
positive in nature (support for reducing illegal parking at intersections and near school drop-off/
pick-up zones) but the majority shared concerns, including “bottlenecking” style conditions created
through parking removal, issues accessing parking lots, the challenge of needing to park further away
and walk when walking short distances is challenging, reduced parking near residences, and impacts
to visitor and service vehicle access, particularly at apartment complexes along Glenwood Drive.
Staff met with Glenwood residents to discuss concerns and this feedback was considered during the
evaluation of the VZIP installations east of 28th Street, which ultimately did not meet the program’s
speed reduction and safety goals.
Furthermore, on Aurora Avenue, staff received a considerable number of concerns regarding reduced
parking on the corridor. This concern appeared to be related to peak parking needs on Aurora Avenue
during pick-up/drop-off for the Boulder Community School of Integrated Studies (BCSIS). Staff met
with residents to discuss their concerns and clarify locations where parking restrictions were simply
formalized through VZIP project installation (like at curb extension locations on corners near stop
signs and near crosswalks)
Future design considerations may include creating curb extensions or pinch points that minimize
the impact of removing full parking spaces. Roughly 14 parallel parking spaces were removed from
Glenwood Drive east of 28th Street, and a typical on-street parking space in the City of Boulder is
20 feet long. Because VZIP-style curb extensions do not present drainage flow issues, it may not be
necessary to use as much curbside space as capital project curb extensions would require.
Pedestrian and Cyclist Considerations
Pedestrians and cyclists shared concerns and confusion with the project team regarding how best to
safely navigate various treatment types. Some active users shared concerns with feeling “pinched” by
interactions where travel lane widths were reduced, particularly where sidewalks were not present (like
on Quince Avenue). Staff responded to the concern on Quince Avenue by converting the treatment to
provide greater separation between vehicles and pedestrians.
Staff launched a messaging campaign to communicate navigation expectations for different users
through various treatment types, including adding a Frequently Asked Questions (FAQ) section to
the project webpage, clarifying that cyclists should either travel with traffic or through the posts
depending on their comfort level and pedestrians should stay on the inside of the installations and
travel through them to cross the street.
25
Snow Removal
Following initial community concerns, T&M staff partnered with the City Attorney’s Office to clarify
snow clearing obligations for curb extensions adjacent to sidewalks. T&M and legal staff found that
property owners are responsible for clearing a five-foot path on curb ramps and extensions within 24
hours after snow stops falling. This finding aligns with Boulder Revised Code requirements for property
owners clearing sidewalks of snow during winter storms, treating the VZIP curb extensions like
permanent sidewalk extensions. For the most part, this approach was well-received and demonstrated
high snow clearing compliance rates.
Maintenance Costs
When budgeting for VZIP treatments, staff attempted to quantify projected costs for on-going
maintenance, including delineator replacement, restriping, and artistic touch-ups. Overall, sign
shop and maintenance staff did not communicate significant impacts to work group programs, but
did indicate that VZIP installations at Aurora Avenue and 35th Street, Mohawk Drive south of Inca
Parkway, and Spine Road near Chaparral Court are difficult to maintain. This feedback was included
in the development of recommendations for each of the treatments documented in the decision-
making process flowchart.
Design Speed
The VZIP projects derived from the NSMP were developed with a target design speed of 20 mph, to
match speed limits determining the appropriate width, horizontal clearance and spacing between
devices, requiring consideration of several factors. These included on-street parking zones, and the
locations of fire hydrants, crosswalks, curb ramps, and driveways/curb cuts. Drainage was also a
consideration, as VZIP-style treatments may create areas where street sweeping cannot reach debris
that may accumulate next to a curb. These considerations, as well as coordination with emergency
and maintenance staff, must be balanced with design speed decisions that would result in greater
speed reduction. Additional project design considerations include community feedback and public
acceptance. Some flexibility is important when considering design speeds and contextual factors.
Design Vehicle Considerations
Staff determined several important metrics to keep in mind during VZIP project design to ensure
treatments remained effective in achieving speed reduction goals while also accommodating the
variety of vehicles navigating Boulder’s streets.
Control Vehicle Types: Generally, traffic calming designs should accommodate turning movements for
an SU-30 design vehicle (for some local streets a DL-23 vehicle may be appropriate). An SU-30 vehicle
is a 30-foot long, single unit vehicle typical of most local delivery vehicles.
Emergency Response Vehicle Design Guidelines: In addition to design vehicle turning movements,
adequate horizontal and vertical clearance will need to be maintained for emergency response
vehicles. Generally, 12-foot horizontal clearance (lane width) from pavement edge to traffic calming
device, or between devices, is preferable for emergency vehicles. The fire department should be
consulted in the design of traffic calming projects prior to installation.
26
Maintenance Vehicle Design Guidelines: Like emergency response vehicles, maintenance vehicles
should have adequate horizontal and vertical clearance to perform essential functions like street
sweeping and snow removal. For VZIP-style installations, delineators should be set back from
pavement markings 12 – 18 inches to allow for sweepers and plows to clear the markings while also
providing at least a 13-foot wide opening between the base of posts (a plow blade is generally 11-feet
wide). Transportation maintenance staff should be consulted in the design in traffic calming projects
prior to installation, and field tests may be appropriate for certain designs.
VZIP VERSUS NSMP
The VZIP was designed as a testing ground for quick-build, horizontal traffic calming treatments –
building off the success of more permanent vertical treatments (typically speed humps and speed
cushions) installed through the NSMP. In general, before and after data collected on NSMP corridors
where vertical speed treatments were installed demonstrated a 15 to 20-percent reduction in 85th
percentile speeds. In comparison, the average 85th percentile speed reduction for VZIP (typically
horizontal) treatments was 5-percent.
For comparison of the VZIP versus the NSMP, two streets that have similar existing conditions such
as roadway width and adjacent land use (residential with few driveways) are Aurora Avenue (VZIP)
and 55th Street south of Baseline Road (NSMP). Each street had similar traffic volumes prior to project
installation, around 2,000 average daily traffic (ADT) and similar 85th percentile speeds (Aurora Avenue
had a top recorded 85th percentile speed of 29 mph, 55th Street had a top 85th percentile speed of
35 mph). One key difference in the two streets is that Aurora Avenue has space for on-street parking
and 55th Street does not, but because 55th Street is much narrower, lane widths are functionally
similar. While Aurora Avenue received a traffic circle and series of curb extensions through the VZIP,
demonstrating between a 5 to 14-percent change in 85th percentile speeds, 55th Street received a
series of five speed cushions that reduced speeds up to 20-percent. Vertical deflection devices tend
to lead to greater reductions in vehicle speeds, though device design and spacing matters in both
vertical and horizontal device applications.
Project Recommendations and Design Guidance
The following section includes a high-level summary of installations that should be removed,
modified, or kept. These recommendations are based on before and after installation data analysis,
review of public feedback, and consultation with the Boulder Fire Department and Transportation
Maintenance Division. This section also includes design considerations for future projects, as well as
general design guidance to apply to project development.

TREATMENTS TO MODIFY
Quince Chicane: Median Island
During the VZIP evaluation period, staff
moved the “No Parking” signs and put in bike
symbols to address community concerns.
After completing the VZIP Project Evaluation
Flowchart for Quince Avenue projects,
staff decided to remove the yellow median
delineators in between the white islands in the
chicane west of 19th Street (see Figure 8).
Before and after studies conducted at the
chicane demonstrated a noticeable reduction
in high-end speeding vehicles, including those
traveling at 30 mph or higher (a 71-percent
reduction) and those traveling at 25 mph or
higher (a 64-percent reduction). However, the city’s maintenance team shared street sweeping
concerns and the fire department found navigation unnecessarily difficult. Ultimately, the chicane
has been modified to reduce vehicle speeds and improve safety and comfort for people walking and
biking. The Transportation Advisory Board Meeting and Public Hearing section on page 38 includes
further details regarding this decision.
Spine and Chaparral Median Island and Curb Extensions
Like the median island on Quince Avenue, the one at this intersection achieved comfort-related goals
but posed maintenance concerns for street sweeping and snowplow clearance. The placement of the
delineators on both the median island and curb extensions should be set back further, allowing for
more horizontal clearance in the travel lane. Overall, the enhanced pedestrian crossing met the safety
and comfort goals of the VZIP.
Glenwood Drive Curb Extensions and Pinch Point West of 28th Street
VZIP installations on Glenwood Drive west of 28th Street, curb extensions at the Two-Mile Creek
Path crossing and Eastwood Court, and a pinch point near Arnett Street met speed reduction and
pedestrian safety goals for the program. However, feedback from community members indicated
that cyclists feel uncomfortable sharing space with vehicles, so this space should be modified by
increasing the spacing of delineators and adding “bike dots” to make it clearer that cyclists have the
option to navigate between the delineators. Sign shop and maintenance staff also expressed that the
posts need more regular maintenance than other installations, which may be alleviated by slightly
setting back the delineators from the pavement markings.
Figure 8. Chicane and Median Island on Quince Avenue
29
TREATMENTS TO REMOVE
Palo Median Island
The median island on Palo Parkway west of Palisade Drive did not cause significant deflection or
travel lane narrowing and was also ineffective at meeting speed reduction goals. The device did not
meet the speed reduction goals of the VZIP and is recommended for removal.
Aurora Curb Extensions at Evans Drive
The curb extensions on Aurora Avenue at Evans Drive did not achieve speed reduction goals as a
standalone treatment. Staff plans to maintain the installation only until the upcoming pedestrian
crossing improvement project (expected to begin construction in 2023) replaces the paint and
posts with concrete curb extensions. The goal of the pedestrian crossing improvement project is to
enhance the pedestrian crossing rather than reduce speeds; with a relocated flashing school zone
sign, concrete curb extensions, and marked and signed crosswalk, T &M staff expects the pedestrian
crossing improvement project to improve driver awareness of children and parents traveling by foot
or bike to High Peaks Elementary School.
Mohawk Drive Treatments
After completing the VZIP Project Evaluation Flowchart for Mohawk Drive projects, the project
team agreed to recommend removal of all treatments installed on Mohawk Drive, including the
curb extensions and medians south of Inca Parkway (pictured in Figure 9) and the curb extensions,
median and pinch point south of Pitkin Street. These
treatments were overall ineffective at meeting
speed reduction goals. Further feedback indicated
that cyclists felt less comfortable biking on the
street post-project installation, which factored in
the recommendation to remove these devices.
Curb Extension and Pinch Points on Glenwood
Drive East of 28th Street
The VZIP installations on Glenwood Drive east
of 28th Street did not result in significant speed
reduction (around 2-percent). Considering parking
Figure 9. Median Island and Curb Extensions
on Mohawk Drive at Inca Parkway
concerns voiced by community members, and recognizing that modifying the curb extensions to be
effective in reducing speeds would encourage drivers to veer left of the centerline, this report finds
that the VZIP devices used on this street are not adequate to meet project goals.
30
Traffic Circle
Before and after studies conducted at the traffic
circle on Aurora Avenue at 35th Street demonstrated
significant reductions in higher end speeders, with a
94-percent reduction in vehicles traveling 30 mph or
higher and a 77-percent reduction in vehicles traveling
25 mph or higher. Staff made early modifications to the
overall installation to accommodate larger vehicles,
and though there may be some potential to modify
materials over time to reduce maintenance needs,
the traffic circle’s design holds promise for providing
significant speed reductions on neighborhood streets.
Figure 10. Pinch Point on Quince Avenue
TREATMENTS TO KEEP
Pinch Points
Before and after studies conducted at VZIP locations
where a pinch point was installed reduced the number
of top speeders (those traveling at or above 30 mph) by
an average of 25-percent. Quick build pinch points hold
promise as cost-effective speed reduction measures.
Speed Kidney
The VZIP speed kidney was an innovative design, potentially the first installation of the treatment
in North America. Before and after speed studies at this location demonstrated only moderate
reductions in average and 85th percentile speeds, but significant reductions in higher end speeders
were observed, including a 98-percent reduction in vehicles traveling at 30 mph or higher and a
90-percent reduction in vehicles traveling at 25 mph or higher. The speed kidney offered a valuable
opportunity to test a new traffic calming device in the Boulder community, paving the way for future
applications in the city.

E. Evaluation and Decision-Making
Framework
Framework Overview
The flowchart evaluation framework detailed below outlines a customizable process which can be
modified as needed for new VZIP-type installations moving forward. The flowchart is a tool to assist
decision-making, but is flexible enough for staff to discuss the outcomes of each stage of the chart. It
is not intended to be overly prescriptive or not allow for exceptions.

PLAN FOR PUBLIC NOTIFICATION
In addition to a Transportation Advisory Board meeting
and public hearing on December 12, 2022, yard signs
were installed along VZIP project corridors to share
whether treatments will be kept, modified, or removed.
The project website was updated to share associated
data and findings. Since the December TAB meeting, the
City’s Communications and Engagement Department has
shared next steps for VZIP projects, including outreach
through city social media channels, city newsletters, and
Nextdoor.
MODIFICATION PROCESS
For those treatments where the evaluation process
determined that modification was the best course of
action, T & M staff plans to work with adjacent residents
and city maintenance staff to design the best project
upgrades that reduce wear and tear, provide greater
durability over time and address resident concerns.

Cost-Benefit Evaluation
In addition to evaluating VZIP projects against safety, comfort, and operational goals, the project
team also considered the project costs contrasted with the potential costs of installing speed
cushions, which would be the lowest-cost permanent traffic calming option available through the
former NSMP. The NSMP is currently discontinued to support funding of the Core Arterial Network
(CAN), described in detail earlier in this report. The project team also considered the cost benefit of
the different types of VZIP treatments by analyzing the cost of reducing speeds per mile an hour.
VZIP AND NSMP COST COMPARISON
For the VZIP projects sourced from the former NSMP Complex Project List (which at the time of VZIP’s
inception had a demand exceeding the program’s usual $250,000 annual budget), real project costs
were compared with the potential costs of installing speed cushions on the project streets. Speed
cushions were chosen because they are likely the lowest-cost traffic calming option available for a
permanent project on these streets, are acceptable to the fire department because they are compatible
with fire trucks and other emergency vehicles, and have proven to significantly reduce vehicle speeds
on other streets in Boulder. The estimated cost of speed cushion installation is based on real costs from
the 26th Street and 55th Street NSMP Complex Projects, both of which were installed in 2021. Because
the VZIP projects were installed in the same year, these cost projections are not adjusted for inflation.

Table 3. VZIP and NSMP Cost Comparison
Table 3 details VZIP installation costs and potential NSMP project costs on the NSMP derived VZIP
project streets. Project streets sourced from the former NSMP Complex Project list were chosen for
VZIP with the acknowledgment that there was not enough money to deliver these projects otherwise.
VZIP offered a quicker and affordable project delivery process to meet community member concerns.
Additionally, the costs of typical outreach processes for the NSMP, such as hosting community meetings,
TAB public hearings, and City Council approvals can be substantial and are not reflected in the table’s
cost estimates above.
34
One project not included in this analysis that is related to the NSMP is the median island on Grinnell
Avenue west of Knox Drive. Transportation and Mobility Staff initially planned on installing a speed
hump on this section of Grinnell Ave. but determined that unfeasible because of an existing icing
problem due to the street slope and crown, and the location of drainage inlets. While a permanent
median island would likely be more expensive than a speed hump, the VZIP median island installation
cost of $793 still demonstrates a significant cost savings (a typical speed hump cost from 2021 projects
is $2,932, and a permanent concrete median may be closer to $10,000).
COST BENEFIT PER INSTALLATION BASED ON SPEED REDUCTION
Analyzing project costs, the project team calculated costs per mile-per-hour (MPH) reduced for each
of the VZIP installations. These costs represent a project benefit; lower costs represent a greater cost-
benefit, whereas a higher cost represents a lower cost-benefit. The table below details these costs per
VZIP installations on project streets.

Table 4. VZIP Installation Costs per MPH Reduced
It is important to note that installations with higher costs per MPH reduced like the traffic circle on
Aurora Avenue or speed kidney on Cherry Avenue also demonstrated greater speed reductions. These
projects were also installed by contractors, contributing to higher project costs and therefore a lower
35
cost benefit. However, for the purposes of this evaluation, these investments appear to be worthwhile
given the observed speed reduction and comparative cost per MPH reduced. For example, the two
pinch points on Quince Ave. also installed by contractors has a similar cost per MPH reduced to the
traffic circle and speed kidney, but less significant speed reduction.
Installations performed by city staff appear to have a significant cost benefit in some locations, like
the curb extensions on Glenwood Drive west of 28th Street and Quince Avenue. While it is unclear in
this analysis if there is always a benefit from staff installation, it is worth noting that speed reductions
appear to be greater on streets where there is more two-way traffic constraints or a yielding condition.
This difference may show that the design details of an installation better predict cost benefit than
design type.

F. Public Feedback
Feedback Gathering Process
The project team recognized that upfront and consistent messaging with the community regarding
VZIP projects would be critical, given their quick-build nature and the application of new-to-
Boulder treatments (such as the speed kidney). T&M staff worked closely with the City of Boulder
Communications and Engagement Department to create an informative webpage, including videos,
descriptions of treatment types, and FAQs, modifying the page to address concerns as they arose.
ONLINE FEEDBACK
Though staff received VZIP project related phone calls, emails, and resident inquires through Inquire
Boulder (the city’s customer service portal), the majority of VZIP feedback (over 300 comments) were
submitted through a Formstack questionnaire on the project webpage. The questionnaire asked
commentors to first indicate the project location for which they wanted to provide input and the mode
they were using when traveling by the project (walking, biking, driving, or “other”). Commenters were
then asked to compare their experience before and after the project was installed, rating their comfort
level from “very uncomfortable” to “very comfortable.” Those who did not have “before” experience to
draw from were asked to just provide feedback on their current experience at the project site.

CHALLENGES
Though the project team worked closely with the Communications and Engagement Department to
provide upfront information and address concerns as they arose, VZIP projects did lead to community
member and resident concerns, including parking impacts, the aesthetic appearance of the
installations, pedestrian comfort, and yielding to oncoming traffic conditions.
The COVID-19 pandemic posed further challenges to communication, considering many project staff
were working from home and health regulations limited in-person interaction between residents and
staff.
Feedback Summary
Of the 318 Formstack comments presented, a few major themes emerged, including concerns
regarding impacts to parking, the aesthetics of the VZIP projects and skepticism regarding whether
they would be effective.
OVERALL FEEDBACK SUMMARY
The project streets receiving the highest number of Formstack comments were Quince Avenue
(90 comments), Aurora Avenue (36 comments), Glenwood Drive from Folsom Street to 28th Street
(22 comments), Glenwood Drive from 29th Street to 30th Street (21 comments), Mohawk Drive (20
comments), and 26th Street and Spruce Street (18 comments).
Quince Avenue: The primary concerns on the Quince corridor regarded the narrowed travel
lanes (including concerns with large vehicles navigating the installations and navigating in winter
conditions), confusion with how to properly travel through the treatments (and related concerns with
pedestrians/bicyclists conflicting with vehicles), and concerns with visual appearance. The most
positive feedback themes regarded appreciation for reduced speeds and safer crossing conditions.
Aurora Avenue: The primary concerns on the Aurora corridor regarded larger vehicles navigating
the traffic circle, unsafe interactions around curb extensions between vehicles and cyclists, and
concerns with project aesthetics. The most positive feedback shared support for enhanced crossing
safety, particularly for those accessing High Peaks Elementary School.
Glenwood Drive (Folsom Street to 28th Street): The primary concerns on this segment of Glenwood
included confusion with how to properly navigate the installations, concerns with the project
aesthetics, and parking removal. The most positive feedback shared support for reduced vehicle
speeds and better crossing visibility.
Glenwood Drive (29th Street to 30th Street): The primary concerns on this segment of Glenwood
involved the reduced number of parking spaces and confusion with how to properly navigate the
installations. The most positive feedback shared support for reduced vehicle speeds and better
crossing visibility.
38
Mohawk Drive: The primary concerns on the Mohawk corridor regarded the anticipated adverse
impact to snowplows, concerns with the project aesthetics, and vehicle drivers and cyclists feeling
unsafe within the pinch point. The most positive feedback shared support for better crossing visibility.
26th Street and Spruce Street: The primary concern at this intersection involved cyclists feeling
constrained navigating the curb extensions. The most positive feedback shared support for reduced
vehicle speeds, better crossing visibility, and more protection from vehicles.
FEEDBACK BEFORE AND AFTER OUTREACH TO COMMUNITY
Prior to the December 12, 2022 Transportation Advisory Board (TAB) public hearing and presentation
of the VZIP Report findings, T & M staff worked with the Communications and Engagement
Department to update the VZIP project webpage to reflect next steps and encourage community
member feedback. This update included before and after data and the recommendations for each
project location, noting whether staff intended to remove, modify, or keep each installation. The
original Formstack questionnaire was modified to ask residents whether they agreed with staff’s
recommendations. Community members were encouraged to attend the December TAB meeting to
provide their feedback during public comment.
Transportation Advisory Board Meeting and Public
Hearing
Staff presented a draft of this report and its recommendations to the TAB on December 12, 2022.
The meeting also included a public hearing following updates to the project webpage and feedback
received through online and on-site outreach. At the meeting, staff explained that the Quince Avenue
chicane recommendation was reconsidered to reflect public feedback and coordination with the
fire department; the revised recommendation is to modify the two islands into a pinch point like the
two further west on the street. This revision reflects concerns about navigating through the chicane
(especially at night), conflicts with driveways near the two component islands, and feedback about
the comfort of pedestrians around the installation. Public comment during the meeting reflected
these concerns.
Further public comment expressed agreement with recommendations to remove the installations
on Mohawk Drive, and appreciation for staff’s efforts to address speeding and safety concerns.
Following the staff presentation and public hearing, the Board voted unanimously to recommend the
proposed course of action on VZIP projects presented in this report, with the modification of the
Quince Avenue chicane to a pinch point.
39
G. Conclusion
Overall VZIP Program Reflection
Overall, the VZIP demonstrated that the city can deliver low-cost traffic calming and pedestrian
safety projects effectively and more quickly than a traditional transportation capital project. Staff
was able to deliver projects on over 15 corridors within a constrained budget in under one calendar
year. These projects can be effective in meeting the goals of reducing vehicle speeds and improving
pedestrian and cyclist visibility and crossing comfort. However, to meet these goals there are tradeoffs
made during the design process to account for the context of each street and emergency response
and maintenance needs. These tradeoffs resulted in impacts to traffic operations and the localized
loss of parking spaces in some scenarios. Furthermore, the Boulder community has expressed
expectations for the quality of materials used in transportation projects, so concerns about the
aesthetic appearance of VZIP-style projects cannot be understated. Communicating the benefits of
these types of projects may mitigate some of the trade-offs and concerns, though T & M staff should
be prepared to discuss the long-term implications of maintaining installations with policymakers and
the community.
APPLICABILITY TO OTHER PROGRAMS
Takeaways from the VZIP apply to other city programs and initiatives, including the Core Arterial
Network (CAN), Pavement Management Program Mobility Enhancements, and installation of
pedestrian crossing treatments. Staff planning future installations of traffic calming and control
devices like those created through the VZIP can refer to this report for guidance on where/how
treatments may be effective, what concerns may arise from the community, and what benefits might
be gained from a potential project.

These bollards are great! Thank you! It stops people from
parking too close to the intersection, my kids can see traffic
around parked cars, and drivers are actually stopping for
us, much more than just the painted crosswalk. My kids are
at the age where they have a little more freedom to visit
the park on their own, and a safer way across Aurora
makes a huge difference. The bollards seem like a
(relatively) low cost, high impact intervention.
I'd love to see more of this kind of treatment on the 33rd-
37th Aurora intersections. Any chance of that happening?

Is the city considering putting speed humps on Aurora
around BCSIS at Aurora and Gilpin? I walk on Aurora every
day and people are clearly going much faster than the
speed limit. A physical deterrent like a speed hump is
much more effect than a sign.

10/19/2020 Formstack Aurora & 39th --- Curb
Extensions Walking Other: More confusing
Survey format is not efficient. There are a variety of
changes on the referenced section of Aurora and it seems
like a waste of residents time to fill out three different
locations for each mode separately. Overall, the project
seems unhelpful and more confusing than anything. There
are now multiple signs, including school zone signs, even
though the speed limit appears to be the same regardless
of the area and whether the lights are flashing. The plastic
delineators don't create the same refuge as an actual curb
extension and are more confusing than anything. They
don't slow cars down or give any confidence stepping into
the road as a pedestrian. 20 mph seems unreasonable for
the street width when school isn't in session. It's
interesting that the photo radar van is deployed on
weekend mornings when school isn't in session and the
street is empty. Seems more focused on revenue than
safety. Overall the project seems like a confusing waste of
money and a clutter of signs and devices. If you want
people to drive slower and peds to be safer, legitimately
change the street geometry so it doesn't function like a
major arterial street. A better place to spend money in the
neighborhood would be the intersection of Mohawk and
Baseline where the alignment makes it difficult for drivers
to focus on peds.

Crossing Treatment
Walking Waiting for a break in traffic to cross
The key problem with this crossing is that the pedestrian
route emerges from below grade, so mutual visibility
between traffic and pedestrians is poor. I expected this
treatment to include some sort of enhanced visibility,
signage, or crosswalk marking. The improvements installed
benefit only a small subset of vision impaired users and
does little to improve this intersection for most users.

Some cars can't make that turn. You guys cut into the road

make the turn. That's the lane I'm biking in. Mr f350 can't

Very UGLY street "improvements" I have lived here 23
years, walk this route every day, and never felt unsafe at
either Grove and 17th & Grove and 18th. I find the car
traffic at 17th and Grove to be very aware and polite. The

I live at 835 Gilpin Drive, six houses down from Gilpin and
Aurora. I've been here since 1977. Having these charter
schools have really impacted the idiot parents who think its
okay to drive poorly and to park where ever they want,
including in front of my driveway. And how dare I
approach them to ask them to move so I can leave for
work! They are rude and confrontational to the point
where I and other neighbors have called the police. The
school is unable to train their idiot/entitled parents to be
respectful of our neighborhood. Can't tell you how many
times these idiot/entitled mommies and daddies have
pulled u-turns in front of the school. Love these new

I live at 4240 Grinnell Ave, the house most affected by this
traffic island. I understand the point of the island but a
couple complaints: first, no input asked from me/us, very
short notification it was going to be installed. But -- since it
is installed, we find it to be cumbersome. Harder to park in
our driveway and also on the curb. The island forces
people to swerve towards the curb as it markedly narrows
the passable street. It also doesn't seem to slow traffic
much. Why not a speed bump? Is there another solution?
Thank you, please respond.

Very bad idea for bicycles. This program is basically
creating obstructions in bicycle passage forcing them into
the road with traffic. Why even build bike lanes of you are
going to do things like this? There are better ways to
control traffc speed.

Other: Nothing, really - I dont
understand why this was
done at 18th and Grove,
which hardly sees any traffic
at all. 18th is a side street and
not a primary entrance or exit
for the neighborhood. Similar
treatments at 20th and Grove
(on the Arapahoe side) and
19th/21st and Canyon would
better serve the
neighborhood.
Love the curb-out extensions, just not at this intersection -
I'd hardly see any cars entering or exiting this
neighborhood at 18th street, which is a block away from
two major entrances: 17th and Grove (a great
improvement) and 19th and Canyon, which I live on, and
still see cars speeding in and out of recklessly from my
balcony and bedroom windows.
18th street north of Canyon and south of Pearl would also
be a better spot for this type of treatment, as lots of drivers
use that segment of 18th to avoid the lights at 17th street
when entering and exiting Pearl and Walnut Streets.

This one works much better than the one at 18th and

Palo (30th to
Ridgeway) --- Median
Island and Curb

Hello,
I was unaware of the comment period for the proposed
vision zero projects for Palo Parkway. I received the
postcard announcing the construction today, and hope my
voice can still be heard. I'm a homeowner on Howe Ct, and
I would like to voice my opposition to these being installed.
I've viewed the proposed design, and I am not in favor of
these being installed. They are to be frank, ugly and
unnecessary. Extended curbs and plastic delineator posts
give the unsightly appearance of a permanent construction
zone. I would maybe understand if this area was
particularly dangerous, but it just isn't. My wife and I have
lived here for ten years with a small child, my mother, and
a dog. We go on walks at least twice a day. It's safe to say
we have crossed Palo Parkway thousands of times in those
10 years, and have never had an issue. I told my 82 year old
mother about this, and the first thing she said was, "Why?
I've never had a problem crossing the street." I have to
wonder how dangerous this street can be if my 82 year old
mother can cross it without any issues. Palo is basically a
dead end street with little to no through traffic. I can't help
but think the city is spending a lot of time, effort, and
money trying to solve a problem that doesn't exist here. I
can't claim to have any data on accidents here other than
my own experience, and if the city can demonstrate that
the street is in fact unsafe, I would possibly support a more
permanent solution that would add to the appearance of
the neighborhood instead of detracting from it. I urge the
city to please reconsider these, and I will be urging my
neighbors to do the same.

I have lived on Quince Ave for 30 years. It is just after 10
pm on a Sat night and I just returned home and was able to
see what the barricaded portions will be like at night on
Quince Ave . I think that you think Quince Ave is wider than
it is. This is a very narrow street as it is .There will be no
room to drive on the street as you have it marked off .
Quince Ave has Bicycle traffic, strollers, walkers, cars, Lots
of repair vehicles parked on the street ( Electricians,
plumbers, Movers, roofers, landscapers and their trucks
etc. ) Where will these people park? How will I even get out
of my
driveway? There will be no room on this street after you
add curbs and barriers. I am very alarmed at this . It seems
like an accident waiting to happen. I am 72 years old and
too old to drive on this obstacle course.
Help!!!!!

Hi,
I live at 1357 Quince Ave. I was looking at the VZIP
treatments you have planned for Quince Avenue, and I
have some concerns. I'm assuming the primary goal is to
slow down traffic, which will result in fewer accidents,
fatalities and injuries...we all want that. However, I think
there's a big flaw in the proposal in that it will only slow
down traffic if there are two or more cars on the road.
When there is only one car, that car will still have the ability
to go way too fast. Quince is a rather wide street and the
pinch points will hardly slow down someone who is
determined to drive too fast. Pedestrians, bicyclists, and
cars pulling out onto Quince from driveways will be in just
as much danger. Actually, it may make it worse for these
groups. Also, I'm not sure why you've limited your plan to
the east end of Quince. We live across the street from
Lucky's and cars drive way too fast there as well. That may
sound surprising given the relatively short distance
between Broadway and 15th, but cars these days have
amazing acceleration, and they're not shy about using it.
I've almost been in an accident any number of times just
trying to pull out of my driveway. Depending on the size of
the vehicles parked along the street, we often have no way
of seeing what is coming, so we are forced to cross our
fingers and hope for the best.
On our end of the street the cars can only park on one side.
But on the east end they park on both sides, and
occasionally you'll get 2 large vehicles parked opposite
each other, which creates a bottleneck and prevents more
than one vehicle from getting through. It's confusing, it's
dangerous, and annoying, and what you are proposing are
several of these types of bottlenecks. When you are one of
the drivers at these pinch points it just feels dangerous

Hi
I live at 1775 Quince Ave and have read your response to
Glen Beans request for information about the island that is
laid out in front of their house.
It is true that 1755 Quince has been focal about all this
however you need to understand that the driveway in
concern is an illegal drive. City of Boulder allows one
driveway per residence. At lease this is what the planning
department have been telling me for 40 years. I was a
General Contractor in Boulder, now retired so maybe
things have changed.
It seems to me that your original plan presented to us
should have not been changed. By the way at that would
have put the bulb out in front of my house where I was
good with.
Hi
It is not the speed controls that upset me but the plan that I
was sent and thought was appropriate is not what was
built. We never received the new design before it was
implemented so I assumed incorrectly that the original plan
was a go. NOT GOOD.
Hi
Thanks for the mass info, but you have not responded to
why we did not get the opportunity to respond to the
existing speed mitigation in front of 1775 Quince Ave
Go back to the original concept that I approved would
handle our objectives.

Hi Liv,
My name is Glenn and I'm a big enthusiast of efforts to
slow traffic on Quince Avenue. We live here and regularly
have cars zip by our 4 year old and twin 10-month olds as
we go for walks, head to school, talk to neighbors, etc.
With that in mind, I wanted to ask a quick question about
some of the pink paint that has shown up on Quince. Most
of it seems pretty consistent with the VZIP plan I found
online, however, there are two "blobs" that don't exist on
that plan. One of them is right in front of our driveway, so
I'm particularly curious!
I drew them on the VZIP plan in pink, and also took a
couple pictures (note mailboxes for reference) and
attached in the pdf.
Could you let me know if these were mistakenly drawn, the
plan is updated, or other? If they ARE included in the plan,
I'd really like to understand better how it affects our
driveway.
Hoping to get this to you before installation starts, which
signs indicate could be next couple days.
Happy to hop on a quick call or zoom if useful. Thanks!
Thank you for the improvements on Quince! Our driveway
opens into the most controversial part - the "yellow
island." While it may not be perfect, it is SO much better
than the unmitigated speed before.
Thank you for experimenting and continuing to improve
based on the data

I got to experience first hand the speed mitigation
modifications that you put in on Quince Ave. I'm a resident
on Quince street and frequently drive, walk and bike on the
street. The center of the road obstacle that you've plopped
in near 19th street is not going to work. You've actually
forced cars into the side of the road where pedestrians and
bikers are located. There are no sidewalks or bike lanes, so
we are forced to walk and bike on the side of the street. On
my bike ride through this area, there were 2 cars coming
from both directions, 2 pedestrians on the other side of the
road, and myself, all being forced into a very small area.
Everyone was confused and I felt unsafe. You have created
a more dangerous situation for bikers and pedestrians than
having nothing there. Maybe it slows traffic down, but not
without a tradeoff.
Please come sit here for a day and observe what happens
with various mixtures of traffic, cars, pedestrians, etc.
You'll see what I'm referring to. Thanks for trying, but you
got this one wrong. Please feel free to call me to discuss. I
would love to see this removed ASAP.
Also, I don't have any problem with the pop outs that you
placed on other parts of quince. The center island obstacle
is the major concern. Thanks for considering.

Dear Ms. Lewin,
The changes on Quince are horrible for this neighborhood.
Many residents use Quince to access vital services at the
Lucky’s Market Shopping Center. With Broadway often
backed up with traffic, you have essentially cut off a second
vital access point to the services and amenities on Quince
and Broadway. The city needs to remove these barriers. As
the population increases in North Boulder, Broadway is not
able to accommodate the traffic that is increasingly coming
to our area of town. This is a poorly thought out plan with a
lack of thoughtfulness about the larger picture in North
Boulder. 300 more residential units will be opening soon in
the Holiday neighborhood, and soon after that, dense
building on the former Shining Mountain Waldorf School
property will commence. If density at this level continues,
the roads need to remain open.
If you want to make Boulder walkable, then you need to
have a grocery store within a half mile radius of Boulder.
Shutting down our roads with all these bizarre barriers isn't
making Boulder walkable. These traffic barriers seem
dangerous and confusing. If Boulder fought harder to put a
grocery store within a half mile of my house, then I would
leave my car at home and walk to the grocery store gladly.
Grocery store access is the REAL problem.

Just talked to your crew - nice people, by the way. The
project is already rolled and so asking for any
reconsideration of this plan is moot. But, please consider
putting two signs on the intersection of 17th and Orchard
Ave; there is a stop sign on Orchard both east and west.
Consider signs on Orchard corners (on post with existing
stop signs) saying "17th St traffic does not stop". I live on
this corner and see near collisions at times and this plan on
Quince may force more traffic onto 17th and Orchard.
Further accident studies could be done to see if a 4 way
stop would be more beneficial.

Please stop this Vision Zero nonsense before it gets out of
hand and subsequently wastes our tax dollars when you
have to remove it all because of the inevitable complaints.
What are these "extended sidewalk" areas supposed to
accomplish that a crosswalk cannot? Where I live, at
Glenwood and Arnett, two cars can no longer drive on the
very-wide street at the same time because of this
nonsense. See attached photo. Boulder is a well-educated
city filled with smart people, but this project has to be one
of the dumbest ideas and implementations I have ever
witnessed. I am a
runner, a cyclist, and a regular pedestrian who walks her
dogs in Boulder and I have not felt unsafe. I am also a
driver who does not want to see extra traffic in town
because of the horribly-designed Project Zero initiatives.
The abundant crosswalks, wheelchair accessible ramps,
and extremely-low speed limits are plenty. I would love to
speak to the people in charge of Vision Zero.

We have the postcard announcing the VZIP modifications
to Quince St.
These are excessively aggressive.
They will push car traffic off of the through street into the
neighborhood.
It is obvious that drivers on Quince approaching 17th from
the west will avoid the three impediments to 19th St by
turning right/south onto 17th St on their way to Orchard
and 19th.
This is a very quiet street where lots of little kids ride their
bikes and scooters to and from school.
That will be a net reduction in safety.
Before traffic accidents increase and someone gets hurt it
would be better to fully think through the consequences of
this design.

Hi Ryan,
My husband and I were so excited to see that the crew was
there yesterday putting up the plastic and painting the roa!.
We have already noticed a difference in the speeds. We
are really hopeful that these changes can become more
permanent structures in the future!
I'm noticing some really negative reactions from people on
NextDoor and I'm worried that those people will have
influence on this project. All of the people complaining are
people who do not live on this road but use it regularly,
some referring to it as a "thoroughfare." I'm pretty shocked
by their
negative reactions and I wanted to ask - if enough people
complain, is it possible that their wants would be placed
above the wants of the people who live here and requested
this project?

Hi I was calling about the Quince Ave Zero vision vision zero
thing that was pretty recently but I'm not sure you guys are
aware of it. In both directions, there signs is a yield of
oncoming traffic. So someone going East sees a car coming
West and both cars or yielding both cars were stopping and
we have to make up our own minds about who goes first.
Whereas you might consider taking down one of the yield
sign so that like if I was going east, the guy coming
Westwood had the yield sign. Or vice versa, or something
like that. 'cause right now is like there's everybody yields.
But who says who goes first? So just a suggestion. My

Feedback on Quince: one lane sections : safety concern
about possible head on with another vehicle. Island
section: difficult to navigate, confusing layout. Overall:
confusing to navigate at night due to large array of poles.
Concerned that larger service vehicles ( utility trucks, home
maintenance providers, delivery, etc.) will not be able to

Opinion: I think methods already in use such as broad

1) Most cars don't know when to "yield" and often times
both cars are waiting for the other to proceed then they
both start at same time then stopt,then start, etc..
2) I rode on my bike down Quince and a car tried to pass
me at pinch point(I was totally aware of car and knew she
was not understanding what to do), so I rode through the
white line area so I wouldn't get hit then the car passed me
for a few yards then slammed on the brakes to stop before
the 1 lane areas(also if I wasn't alert I would of crashed into
car). Then after that car proceeded the oncoming car didn't
yield to me and I had to move out of way again. So out of
riding down Quince one time I almost got hit by a car 3
times. The way it is set up makes it extremely dangerous
for bikes.
3) The Chicane section has 2 one lane wide areas in both
directions that is to long so cars can both start to go and
then get stuck in the center.
4) Many kids from Centennial middle school walk to Luckys
and I believe what the city did has made it very dangerous
for these kids.
My conclusions:
1) I think it made Quince very dangerous for bikes and
pedestrians

To me the "innovations" are absolutely awful looking. I am
displeased in general with the ever-increasing amount of

so ugly. The street looks absolutely ridiculous now. Beside
this it seems like it's more dangerous than helpful. It is
particularity dangerous for pedestrians near the "island"
area. Cars are forced to the edge of the road and there is
no place for pedestrians to stay clear of traffic. I use Quince
to get to Lucky and I always drive safely and respect the

everyone else using the street. I don't think this makes the
street safer in any way and it is highly inconvenient and
dangerous to drivers, cyclists and pedestrians alike.

Hello Amy. Bob Yates gave me your name. I live in North
Boulder and use Quince Street as a direct route to Lucky’s
from my home. I’m concerned about the labyrinthine
design of the barriers to (apparently) slow down/ stop cars.
It is unclear, especially on a first pass how to navigate these
and if 2 cars or a car and a bike attempt to p ass through
the “narrows” at the same time it’s a sure invitation for an
accident, especially at night. I hope the design is just a trial
(like the failed experiment on Folsom a few years ago.) I
would call it a well meaning overreaction to the desire to
slow cars down. Maybe the good old fashioned speed
bumps would be safer, cheaper, and less dangerous.
Thanks.

The pinch points (white 'islands') east & west of the

It is very difficult to turn into our driveway now when

This is feedback about the PROPOSED project on Glenwood
Dr. between Folsom and 28th St.
I travel that street regularly to go to Safeway, my bank, my
veterinarian, and (to a lesser extent) a used bookstore.
I'm not sure what perceived problem this project attempts
to solve, but turning a two-lane street with one lane of
traffic in each direction into a street with one lane (actually
maybe 1.3 lanes, but anything < 2 lanes is a problem with
traffic in both directions) where vehicles going in opposite
directions have to compete for the use of the common lane
is a recipe for head-on collisions.
I have not experienced, or noticed any problems on this
street.
Yes, there is a bike path crossing, so drivers (or other
cyclists) have to be wary, especially since bikes on the path
can come from behind a driver going east.
I can only assume that the expected result is that drivers
who don't like to play "chicken" will use Iris or Valmont to
travel east or west, further clogging those main streets. At
best, cars waiting to use the common lane on Glenwood
will be sitting and idling, creating more pollution that would
not have been created with the 2-lane configuration.

Hi, my name is Aaron. My phone number is 3032463837.
I'm a resident of Boulder. I have a question about these
Vision Zero changes. I'm just not sure how I'm supposed to
drive through them 'cause there's not room for two cars.
It's seems like a real hazard so I just like a little bit of
information on that. If you guys were planning to remove
those what the deal is, please call me back. Thank you bye.
Boulder City Council Members,
I live off of Glenwood Drive in North Boulder and am
concerned about the new traffic inserts under construction
on Glenwood Drive between 28th and Folsom and the
negative safety implications of this measure. Vision Zero
claims to be a "data driven" approach to limit traffic
fatalities and injuries to zero, but I checked city data on
traffic incidents on Glenwood Drive, where the new inserts
are being installed and there were zero reported accidents.
This is a negligent waste of city resources and worse, these
new inserts:
-Limit parking in an area with limited public parking
- Make the street more dangerous forcing cyclings into the
flow of traffic
- Make it more difficult for residents to get out of their
streets and onto a major road
- Provide no sensical safety improvements
This letter is a formal request that these traffic inserts are
removed immediately.
Given we are in election season, we find ourselves with a
great opportunity to support the candidates that take
action to remove these traffic inserts and will be continuing
to organize with our neighbors to do so

Boulder City Council Members,
I live off of Glenwood Drive in North Boulder and am very

- Make the street more dangerous forcing cyclings into the

- Make it more difficult for me to get out of my street and
onto a major road
- Provide no sensical safety improvements
I want these traffic inserts removed immediately.
I will be contacting neighbors to write to you on the same
subject. Given we are in election season, I will be sure to
attach all of your names to my flyers that I will post on
Glenwood near the traffic inserts.

I agree that Quince St needs work, but the new traffic
mitigation efforts are not realistic. Turning this street into a
one lane road, in sections, is simply dangerous. Also, I find
I must come to a complete stop and let my car idle mid-
street while oncoming cars pass through the new cones. I
can't imagine the residents of the homes along Quince
appreciating the extra car emissions created by all this
stopping, speeding up, and idling. I know North Boulder has
voted against sidewalks
in the past; however, it seems offering a safe place for
pedestrians to walk on Quince would create more harmony
between drivers, bikers, and walkers. Also, these new
traffic conditions seem impossible to maintain in inclement
weather. Many of these traffic "solutions" are based on
cities like Palo Alto who do not have winter precipitation. It
is infuriating to have so much taxpayer money wasted on
expensive projects that are unsuitable and unsustainable in
a Colorado climate. Thank you for your time.

Was hoping to find your number and leave a message… but
didn’t find it. So in a nutshell… Can we put in a center line
on Glenwood between Folsom and 28th?
I live directly behind one of the new plastic post
installments on that stretch of Glenwood. I was on the first
zoom where you presented the strategy back in March. I
wrote in in favor of the plan fyi.
I notice that there’s a center line on Glenwood between 28
and 30th, but not on Glenwood between Arnett (or
Folsom) and 28th.
Are the widths of those 2 streets the same? If so, I’ve found
that the center line makes for a friendlier drive though in
those places that are now being narrowed by the new
lines/posts. It’s my intuition that the stretch behind my
townhouse west of 28th is psychologically more of a
speedway and give the illusion that the street narrows to
one lane. It's my hunch that painting a line down the
middle will ensure that there’s still 2 lanes there and drivers
need to slow down to stay within lanes. Since last week,
I’ve noticed and I myself seem to drive thru the middle of
that narrowing, as I approach Eastwood Ct to turn south
into Willow Brook to get to my townhouse. I believe
painting a center line, will encourage drivers to stay within
the lanes and consequently will have to slow down to do
so.
I spoke with one of the installers a half hour ago who gave
me your contact. He told me that someone else also
suggested that to him yesterday. Hope my comments help.
Feel free to contact me if you’d like to discuss further.

Ms. Lewin,
Never in my 65-plus years in Boulder have I seen or
experienced anything as ridiculous and demented as the
Vision Zero Innovation Program (VZIP) implemented on
Quince St. An accommodating sidewalk system and road
widening would accomplish more than the stupidity of
VZIP. The City is inviting head-on vehicle confrontations
and accidents via the bizarre policy it has adopted. If dog
walkers, bikers, and joggers had access to established
walkways and bikeways, instead of blocking vehicular
traffic with their erratic behaviors and antics, much
confrontation could be resolved. I drove professionally for
about 11 years, including 8 1/2 years with RE-2 schools and
most of its mountain routes. VZIP is a mess. Personally, I
will drive down other streets (and contribute to their traffic
problems) rather than try to navigate VZIP.

before. These all seem like really poorly planned
"solutions" to a problem that doesn't exist. I hope this ends
up like the worlds largest bike path we had on Folsom and
is quickly reverted to a reasonable and not stupid
implementation.Get rid of it. These pinch points and

Hello Ryan,
You may recall Joan and me who represent the Orchard
and 15th neighborhood who requested speed bumps to
slow traffic on our street. You advised that people were not
driving fast enough. We disagree.
What I find incredulous is the mitigation done on Quince.
Seriously, what is wrong with speed bumps? They are
cheap, effective and easy to install. I've helped build them
in Mexico. They are effective!!
Quince needs mitigation, no doubt, but who was the genius
who thought of the silly posts? Bikes and pedestrians are
forced into traffic. Drivers are pissed, etc. But what I gotta
see is a snowplow coming down the street - that will be
entertaining!
Put in speed bumps that allow for bikes and pedestrians on
the sides and cars to slow down in the middle - they work.
Snowplows can come down the street. The developing
world has been using speed bumps for years. I am not sure
why Boulder needs to reinvent the wheel.

I live on 15th and Orchard and bike frequently with my
young children and alone. We cross Quince on foot or on
bike twice a day everyday at a minimum. We cross both at
15th and at 17th. I was hoping the Vision Zero project
would make that experience safer seeming. Unfortunately I
think it's had the opposite effect at 17th and no or only
minimal impact at 15th. At 17th the crosswalk desperately
needs to be repainted. Now with the bollards and the
bump out from Vision Zero the crosswalk is even less
visible. Twice in the past week I've had cars blow past me
and my 7 year old child as we've stood waiting to cross
Quince on 17th. I think they're so distracted by the new
pattern they don't even notice pedestrians. At 15th and
Quince you have the two northbound stop signs but traffic
doesn't have anything slowing it down going eastbound
and now with the pattern changes on Quince I think people
see that coming and are even less attentive to pedestrians
crossing. Going westbound the slowing of traffic with the
bollards is far enough away from 15th that they speed up
again by the time they get to that intersection. I really wish
there was a 4 way stop at that intersection or a speed
bump w Ped Xing.

These new road-narrowing installations are visually
distracting and confusing for drivers and, I assume,
pedestrians and cyclists as well. To me, they just put
vehicles in closer contact with each other and with
pedestrians and cyclists. I genuinely believe they are
making these roads more dangerous. On Quince, how
about installing sidewalks and/or bike lanes instead? At
Spruce and 26th, it would be better to change the parking
back to parallel parking for better visibility. These
barricades are too flimsy to actually prevent an accident
and are more likely to cause one. They are awkward to

You do not have Upland on here though I believe we were

would be the case on a street that sees numerous cars,

impossible to see who arrives first to go through. Uplands
sidewalk is choked with weeds meaning people have to
circumvent the chicanes somehow, not to mention we get
no snowplows making the street even more dangerous.

The traffic circle and "pinch points" at Aurora and 35th is a

Why would you put in someone's idea of a "solution" when
there was never a problem?!
Today was my second time going through it and we 3 cars
that approached almost had a crash. If you add a bicycle or
pedestrians to the scene, it becomes even more
dangerous!
My neighbors and I were perfectly happy going 20 mph on

In case you don't know, there is a school a few blocks

It's now ONE lane with no process. People SPEEDING up to
beat people coming from the other direction so as not to
wait. If one side has multiple cars then the other side has
to wait because no one alternates or is polite. So people
waiting too long just give up and barrel through causing
close call accidents not to mention road rage. There was
NEVER a problem here for cars or pedestrians. Yet you are
trying to force people onto 28th and/or Iris where there

My view: the one-lane, interweaving traffic is more
dangerous than allowing normal lane traffic. The speed
differential is not that significant. If a driver sees no one
ahead, they will proceed at normal lane speed, simply
weaving in and out of the cordoned off areas. This weaving
is more dangerous than normal lane traffic.

9/29/2021 Formstack 9th & Cascade ---
Curb Extensions Driving Conflict with turning vehicles
There is parking on both sides of Cascade on either side of
9th street. Cascade is not a very wide street. When there
are cars parked on both sides of the street (North and
South), there is not enough room for a wide turn from 9th
street onto Cascade. It is not unusual to have a close call
as cars turn from 9th onto Cascade, and because of parked
cars on 9th street, one often cannot see the cars coming up
or down 9th when waiting at the Cascade intersection.
Then, because there is so much traffic, there is a
disincentive for turning vehicles to slow down. Now, with
the new curb extensions, the turning cars will have even
less room to carefully make that turn. Many times cars
turning off 9th shelter at the edge of the intersection to
allow Cascade to clear, and they will not have that option
with this infrastructure. Even putting the curb extensions
on the south side of the intersection would be safer. Also,
there are people crossing at Euclid and Aurora also. Why
only at Cascade? As a separate matter, it would be wise to
post signs to encourage cyclists to use Grant or Lincoln,
rather than 9th street, for uphill climbs. 9th is too busy
with moving traffic and parked cars to have cyclists
struggling up the hill.

We live on 8th Street.
We turn left, north, into 9th off of Cascade. Hard to see

onto Cascade we have to turn so wide because of the new
polls we turn into on coming cars. There will be accidents.

Conflict with turning vehicles
I do appreciate the attempt to control speeds, but the
island configuration is not working. The traffic
configuration in front of our house at 1775 Quince, is
horrible. There's a sign in front of our driveway which
makes it difficult to enter and exit our property. Many
cars, and especially trucks, drive over the signs. Several
times a day vehicles blast their horns in frustration which is
unsettling. Drivers have yelled at us thinking it was our idea
to implement this project, when we really had no say in this
installation. Lately, cars are challenged by the obstacle
course, speeding through. Parking is definitely a problem
especially for service people like lawn service, deliveries.
To have multiple visitors, they will need to park a block or 2
blocks away. I do invite anyone to come to our house to
experience the challenge. I've given this new situation a
month. I do appreciate that traffic speed has decreased,
but ask that the city return to the original plan of
"trapezoids" rather than the island.

Walking Speed of vehicles Vehicle speeds were reduced
Having lived on Quince for over 30 years, I am glad to see
an attempt to slow the traffic down. Vehicles still travel 40-
50 miles per hour when no one is coming toward them. I
feel like more needs to be done. Maybe more chicanes? I
think speed bumps are the answer. Right now it is like a
slalom course for drivers. We have people driving down the
street honking all the way and people purposely hitting the
poles to express their dislike. School kids walk up and down
the street in herds twice a day. There are many bikers and
walkers. It's still not safe, I urge you to do more! Thanks for
trying tho!

I applaud the goals of Vision Zero. The implementation on
Quince as it currently exists is flawed, makes the street
now dangerous for both drivers and cyclists. The narrowing
at 19th and Quince is dangerous. Cars turning onto Quince
from 19th have right of way, but it's difficult to turn onto
Quince if there is a Carr waiting to turn onto 19th. The
places where the street narrows are very confusing. Both
sides have yield signs. Frequently the sun is in your eyes,
making it even worse. Not clear where cyclists ride. Cars
and large canvas sometimes park inside the island
narrowing the road, forcing cyclists into the narrow driving
lane. This project feels dangerous. Many drivers are simply
avoiding Quince. I don't see how forcing traffic to other
streets does anything but move the problem.

I question "vision zeros'" necessity. Looks more like a

the turnabout/circles in the intersections; and, lower some
of the speed limits. Yesterday I stopped for a car that was
in the circle. There was no way I could tell if the driver was
going across Aurora or turn left on to the cross street on

stopped for a few seconds until I was sure it was safe to
drive into the intersection. Apparently this driver had no
idea that I might have collided with that car, if I had
proceeded w/o knowing where that car was headed. And
BTW your "Drive 25" signs on Twin Lakes Rd are really
stupid. Traffic on Williams fork and TLR, by Stonegate and
Twin Lakes Condos should be about 20mph. There are
many driveways and blind corners. Also, the nice multiuse

Dear Amy,
I wanted to withhold comment until I had an informed
opinion.
Re: Glenwood
As previously discussed, my home is ON Glenwood and
Arnett. I drive between Folsom and 28th almost every day
and between 28th and 30th, regularly.
Folsom to 28th
I don’t have a strong opinion about the bit near the
Safeway entrance or at Arnett. However, the bottleneck by
the Willowbrook entrance, with THREE bump-outs is
absolutely awful. The other day, I was behind five stopped
cars on a what should be a through road. Maybe keep the
bump-outs on one side of Glenwood or the other, there,
but not both. It’s ill-advised and dangerous.
28th to 30th
Another accident waiting to happen. And it looks like it
already did, the other day. I only saw the emergency
vehicles from 28th and Glenwood, but I’d bet anything that
an accident was caused by these stupid mitigation
obstacles.
And while from my little NIMBY perspective, the whole
Limited Sight 20 has some appeal, quite frankly to make
make Folsom to 30th on Glenwood, a 20 limit, really is
bullshit. It’s a neighborhood through street.
My 2¢. By all means, put up one of the speed readout
things. (I know those consistently, effectively modify my
behaviour.) And even ticket anyone doing 30. But 20 is not
a reasonable expectation here and while I could tolerate

Traffic Control Experiment on Mohawk Drive and Aurora
Avenue
Resembling a chronic construction zone
My primary concerns are:
1) Is it necessary to control traffic on these streets, with
more than normal signage?
2) If it is necessary, is the current arrangement the best
way?
3) What data is the city using to determine the success or
failure of this project.
CAN WE HAVE A PUBLIC MEETING BEFORE A FINAL
PROPOSAL IS ENACTED.
My observations:
I am outside at least a two hours per day and have not seen
any changes in driving behavior. Those who were already
going slow continue to go slow, while habitually fast
motorists are now using the obstacles as a slalom-style
race course. I have NOT seen city employees monitoring
the success or failure of the project.
The plan is ugly, leaving the two streets resembling a
chronic construction zone.
The layout is more dangerous for bikers, pedestrians, and
the newly introduced scooters, based on observation.
Fire trucks, garbage trucks, delivery vans, and other
modestly large vehicles are or will havea difficult time
navigating the layout.
The white lines have eliminated a substantial amount of
parking. Cars parked regularly in those areas as de facto
personal spaces were already serving the same purpose.

Dear Ms. Vandenbrande,
My wife and I participated in the recent online conference
call regarding what the city was planning to do to reduce
traffic speeds on Aurora and other streets in Boulder. This
morning I see that you have started installing these barriers
despite the strong objections we and others have made
that noted the negative impacts these barriers/bollards are
going to have for the residents that live in the
neighborhood.
Aurora is THE primary parking “lot” for the staff and
students that refuse to pay the parking fees imposed by the
University at the research parks on Colorado Avenue.
Since the neighborhood between Colorado and Aurora was
designated a restricted neighborhood parking sector, most
of the research park facility users simply started parking
along Aurora, or more frustratingly, on the side streets of
34th, 35th, and 36th Street between Aurora and Baseline.
At the end of this note is a photo of the cars parked on
Aurora between 35th and 36th streets, on a “light” day!
Typically every available parking space on Aurora is filled
every Monday through Friday.
As we live at 865 36th Street, we already have people park
in front of our house every day. When Aurora gets plowed
in the winter, all those people park on the side streets
because the heavy plowed snow covers the available
parking space. I have often spent hours shoveling the
sidewalks and spaces in front of our house so we can have
access for our personal cars, only to find those spaces
quickly filled by research facility staff and students. I am
sure you can understand how frustrating it is to come back
from the grocery store and finding all the parking near your
house taken and you have to park half a block up the

Hi, I live at 775 Mohawk Drive where speeding has been a
problem for as long as I have lived here. I was initially very
excited to see the city's speed mitigation plan for Mohawk
and Aurora and sadly disappointed to see the unsightly
markings, bikes nearly getting hit where traffic gets
pinched, my son has personally crashed into one of the
white sticks and been bloodied and the same speeders
STILL speed through our neighborhood and now seem
entertained by a slalom of sorts that has been created. I
realize this is not the nicest part of Boulder, however if you
drive through Mapleton Hill or Newlands, you see some
very attractive looking and effective forms of speed
mitigation and this doesn't seem like the same type of
effort put forward. I've also yet to see anyone from the
city measuring the impact. Aside from being unsightly and
dangerous to cyclists, what does the data say is happening
with the speed of traffic?
I'm a concerned resident the lives on a dangerously fast
street in Boulder and would like to see more from the city
being done. The latest efforts are not up to Boulder's own
standards as set by what has been done to date in other
parts of the city.

On Aurora between 30th and Mohawk we have a lot of

35th, there are white lines and posts, plus a traffic circle.
There's barely enough room to get through. I watched an
ambulance and fire engine try to navigate it which was
impossible without hitting some of the posts, and any large

I'd hate to drive around it in a big car

harder.
The anti-parking stance in Boulder sure isn't "inclusive" of
an older person with serious mobility limitations like me.
There's no way I can do errands and carry groceries or visit
family and friends by bus or a damn scooter; I use a cane to
walk and can't manage long distances. And of course there
are no handicapped parking spaces on residential streets,
so putting up structures that make it even harder to park
on them is very discouraging.
I've taken to shopping in Longmont because I can park so
much closer to stores. I've switched my MM dispensary
from the Pearl St Mall to Lyons for the same reason. I used
to be able to park in one of the handicapped parking spaces
in front of Helping Hands; now that's a pedestrian block.
It's just as fast, and a lot less stressful, to drive to Lyons and
park in front of the dispensary there than to get to HH. Too
bad; I love the Pearl St Mall.
I watched the same thing happen to my mother as she
aged; she switched from buying books at the Boulder

I'd like to thank the city for improving the traffic calming on
Aurora Ave. I have two suggestions:
1) Please extend calming measures west, to 30th. In
particular, a speed table at the crosswalk from Arrowwood
park near Quinn would help cut down on the speeding that
still happens between 30th and 35th. I have had some near
misses using this crosswalk before.
2) Some protection for bikes on the street would similarly
be helpful. Perhaps bike lanes at intersections to help
navigate the tighter intersections.
3) Making the roundabout permanent and deploying speed
table down the street may do a better job at reducing
speeds. Many speeders simply weave thru the current
controls. A permanent roundabout could be planted and
would look better than the current (somewhat temporary
looking one)
Otherwise, I am happy with the attempt to solve a huge
issue in the neighborhood-- the speeding. Thanks!

As far as I can tell, the traffic control experiment on
Mohawk Drive has not caused people to drive slower on
my street. Additionally, the lack of street parking now
means that at almost all times cars are parked within a foot
of either side of my driveway and I have no where to put
my trash bins (besides blocking the driveway with them).
We already have a shortage of street parking due to the
school on Aurora, so this traffic control experiment is
exacerbating an existing problem in the neighborhood.

As I'm filling out this survey just now, saw a half dozen cars
over 30 or 40mph, so not 100% sure new installations are
preventing speeding on my road, however I've appreciated
some of what I perceive as additional safety and visibility
from cars not being able to park directly in front of my
house. Have noted the Western Disposal struggling a bit
with enough room to lift and return
trash/recycling/compost bins, but that's really the only
issue I've observed.
Side note: I like the new traffic circle on Aurora - definitely
a good reminder for me, as coming off 30th so easy to
forget to slow down.

Exactly how are the snowplows supposed to go down
Aurora Avenue and Mohawk Drive with the recent
"temporary way to control traffic?" Or is it your intention
to stop plowing both streets. I was under the
understanding that if there was a school or the road was
used by public transportation. It seems as thought the
buses are gone, but the two elementary schools still
remain.

Baseline & Mohawk ---
Traffic Calming
(Hardened Centerline)
Barriers on Mohawk Dr. has done little except to space the
cars in traffic of Mohawk Dr. where it turns into Aurora St.
Cannot get out of my driveway without a long wait from
the traffic in the morning and afternoon. This is shortcut
through the neighborhood instead of using 30th to go the
Aurora 7 school. Air is filled with carbon monoxide in front
of my house. The curve is also too narrow because of
street lined with parked cars so that I often see moving cars
going across the center line of the curve.
After the cars from Baseline are on Mohawk Dr. towards
Aurora St. get through the barriers they actually speed up
because the 15mph sign is not easily seen and there appear
to be no barriers. This is a very dangerous curve that is
parked on and the cars are not expected to be parked
there, so they pull over the crossline on the curve.
Suggestion: The section of curve over the creek and the
bike path tunnel should be closed to cars this would
eliminate the shortcut now being used in the neighborhood
instead of the traffic regulated route between Baseline and
30th St. The ends of Aurora St. and Mohawk St. could
have a permanent barriet. They would become dead ends
but have a walk across which would also make the bike
path continuous without having to use the underpass. It
needs a pedestrian crossing there anyway. That would be
perfect to eliminate unncessary and inappropriate traffic
and dangerous parkikng.
The turn around on Aurora St and 35th is ridiculous. I have
stop and go 2 mph (not mph) to make it around the circle
without hitting a sign. That street has dangerous parking
near the Mohawk Dr. curve. It also has people confused as
the street changes name there

I bring a jaundiced eye to the purposes of any attempts at
blocking or forcing traffic. I believe they almost always
make things worse, especially as bicyclists, and sometimes
pedestrians, are often emboldened to act stupidly when
efforts are made to protect them.
The best protection, in my view, is to teach bicycles and
pedestrians to interact intelligently with cars.
Through the years, I often find myself having to share the
road, in the dark, with bicycles without effective lights or
reflectors, and with dark clothes. I also often finding
bicycles riding side by side, and edging out of the bicycle
lane.
I don't remember having any particular problems passing
along Quince, hundreds of times, both as a driver or as a
pedestrian. Traffic there is usually light. All of these plastic
pylons are the worst thing that I've experienced.
I was no great fan of the effort to reduce many of or 4 lane
streets to two lanes. It's fuzzy thinking to imagine there's
something to gain from creating or worsening traffic jams,
and this vision zero mess looks as poorly thought out as
that.

I own a home at 4125 Aurora Ave. The increased flexible
poles and markings are not slowing down people who drive
fast, most concerningly by the school. I'm concerned for
large public safety trucks and plows through that area. I
don't think they increase safety, and it's annoying to deal
with them daily.
The constrictions near intersections, and some placed
without obvious purpose away from intersections seem to
make Mohawk & Aurora less safe for bikes and scooters.
Instead of easily passing bikes, some cars will try to
squeeze by them before the poles, and the way the poles
are laid out, there is not a path for the bikes on the right
side of the constriction. Cautious drivers will slow for bikes
to go first, but many will not. These traffic markings seems
poorly executed and I request they are taken out.
Intermitent speeding is certainly an issue, but typical speed

It's hard for me to imagine that whoever designed the new
traffic obstruction devices ever visited my neighborhood.
Aurora is one of only two east west streets we can use to
navigate our world so it's very busy with pedestrian, bike,
skateboard and now lime scooter traffic (as well as a lot of
speeding cars); there are a lot of kids and a lot of dogs, and,
by the way, two elementary schools.
You've created obstructions that reduce the safety of the
people in the neighborhood while doing nothing to reduce
speeding. Cars slalom through the posts and weird white
circles that no one understands at 34th and 36th streets
and then tap their brakes and see how fast they can
navigate the roundabout at 35th. They are back to driving
30-35mph within a block. So...the speeding hazard remains
but I have now lost the ability, as a pedestrian, to safely
cross three intersections. I have already seen some very
near misses that could well have resulted in serious injury
or possibly death. It's really only a matter of time.
Why couldn't you put those wonderful panels showing your
actual speed on Aurora and then do some actual
enforcement? We get the occasional radar car--usually on
a weekend parked in a spot between 33rd and 30th where
cars are already starting to slow down, but I have never
seen police or city enforcement issues stopping cars and

I have no issue with trying to mitigate speed etc on Quince,
but this current configuration is confusing and seems
designed to create a head on collision. It still forces
pedestrians to walk in the road.
You'd get the same results with fewer issues by putting in a
4 way stop at Quince and 15th and putting up a few speed
bumps.
The chicane is confusing, requiring a driver traveling west
on Quince to move into the oncoming lane and then out
again for no apparent reason. It's confusing and dangerous
as well as poorly marked. The pinch points further along
reduce to one lane without as much confusion. I don't care
for that solution either, but at least it's clearer and less
dangerous. Why not speed bumps, instead? Why not
sidewalks on one side of the street (narrowing the street at
the same time)? I walk on Quince also and feel less safe
with this arrangement.

The pinch points cause moments of indecision over right of
way for drivers and cyclists traveling the same direction in
the traffic lane. There isn't room to be side by side, but
drivers aren't always willing to let me take the lane either.
Riding between the bollards is a visibility nightmare, and
will soon be a debris and ice nightmare too. the previous
road width allowed for a lot more space and choice about
proximity to cars. Surely there are better ways to slow
down car traffic.
I ride this section daily in the morning and afternoon. In the
afternoon around school pickup time, the new design has
created a more hazardous situation than was present
before. The visual clutter and narrow lane means cars can't
figure out what to do when I (a cyclist) am present. They
can't decide whether to accelerate and beat me to the
pinch point or let me stay in the lane. As stated earlier,
riding IN the bollarded-off paint has its own problems. And
what message are we sending to cyclists if we're
encouraging riding within these painted off zones. I know
there isn't room on Mohawk for a bike lane AND parking,
AND I know that narrower lanes slow cars, but this solution
is a mess.

I agree that recently some young/college students and
even some repair and construction vehicles have been
speeding and roaring their vehicle engines.
But using the temporary "construction zone" like reflective
posts is not attractive in our neighborhood and I would say
has had limited success slowing our traffic.
The college boys down the street apparently were talked to
before the construction zone posts were installed, because
they slowed down and quieted down several weeks before
the post were installed.
As far as what would be much more effective, less
dangerous to us senior citizens and better looking in our
neighborhood, I think the raised crosswalks on 55th street
would be a much better solution. If water runoff is an issue
then I think a wide speed dip is a second option.

This is not a solution people are familiar with or
comfortable with. It is so confusing the first time you
experience the pinch that people stop in the middle of the
road to figure it out causing vehicles behind them to brake
harder than expected and get frustrated. I've even seen
people drive between the poles incorrectly on the outside
of the swerve pinch. There are yield signs on BOTH sides of
this pinch which causes more confusion. Cars leave the
pinch frustrated and accelerate quickly which defeats the
whole purpose if you are trying to get people to slow
down.
The curb extension pinch areas are horribly tight so
sometimes you need to yield and sometimes you don't -
more confusion. Sometimes people gun it to get through
first. The distance is far enough between the pinch areas
that people don't know if they need to yield from the start
or as they get to each one.
I could go on. I haven't even gotten into how confusing and
utterly unsafe it is for bikers and pedestrians - I have seen
many near accidents! And what will happen in winter??
There is no way this will work with snow on the ground.
This is a HORRIBLE solution to whatever problem you are
trying to address on this road. I imagine it's for speed but I
assure you it's not working. I drive this strip of road
frequently in my work commute and it's not getting any
better. No one slows down except at the pinch points
briefly then they accelerate and swerve all over the road. I

Thank you so much for this project. While there's always
the occasional jerk who tries to cut people off or speed
through it, by and large it has reduced traffic and really
slowed people down to pay attention. A neighbor's dog got
loose right in that area of the slalom last week, and traffic
was able to stop in time so it didn't get hit. I'm not sure the
result would have been as positive before this. Also, the

Your feedback form doesn't provide the space for the
comments and concerns I have about the project. I have
lived in Boulder since 1975 and watched as the roads have
been closed or otherwise changed to impede traffic. It just
pushes the traffic onto other streets. Quince is a feeder
street to get to Broadway. If we all have our share, then it
works. The changes on Quince are confusing at best, and
dangerous at worse. I noticed the school bus can no longer
use Quince and is now using Orchard. How will the street
be plowed once the snow arrives? While I understand the
need to address speeding on Quince, the installations are
confusing and dangerous. Why not put a stop sign at 17th
and Quince? At least folks know what to do with it. My
last trip on Quince almost resulted in an accident--the west
bound driver didn't know where the road went through the
chicane and almost hit me.
Further, I don't feel comfortable walking on Quince any

Please don't make it a one lane street--there has to be a
better alternative than what is currently proposed. Give

As I use Aurora Ave to pick up grand child from BCSIS

and school busses on Aurora are laughable. Striped speed
bumps would do the same without the visual assault.
As a property owner on the 2100 block of Upland Ave, I am

I live on Quince Ave. and am use the road as a driver,
pedestrian and cyclist. This project is dangerous. I have
witness confusion and near-accidents. It is also a very
unappealing project visually in front of my house. I fail to
see the value in the project. What issues occurred
specifically on Quince Ave. prior to having this project
installed? I realize cars can often speed, but it is a very wide
road and pedestrian danger is not an issue. My neighbors
and I very frustrated by the lack of engagement and
rationale for this project.
Please call me to discuss at 720-272-7476.

Before the structures, often cars would pass at ridiculous
speeds, especially downhill (going east) to be the first at
the crossing with 19th. With these structures, vehicle
drivers seem to be more considerate, as they already had
to slow down for the chicane. Personally, I would like to
have one or two speedbumps along that stretch of the road
(15 - 19) but this is already so much better. Thank you

Please remove the center island. It pushes cars into
pedestrian and bike pathways. I would like to see the
results of your traffic study on Quince Ave. I maintain that
the center island is a problem, specifically because it causes
cars to drive in the only space available to pedestrians and
bikers. As the days are getting shorter and darker, this
presents an increased danger. If the vision zero project is
about protecting pedestrians, you need to take down the
center island. Thanks Jesse

Biking on Quince is improved with the exception of the
area where there is a modified round-about sandwiched
between two separated pinch point areas (hope that
makes sense). I like being separated by the traffic by the
bollards but when cars and bikes/peds all feed in together
after going around the modified round-about, it can be a
bit dicey.

I do think that some drivers, especially at night when
visibility is pretty low (no street lights), have some trouble
navigating the round-about thing. And some drivers seem
confused by these changes and will either pull over and
wait for someone way too soon (when they clearly were
there first), or they will blast through it to get through it
first. I think it's because in the US people just don't know
how to deal with round-abouts, etc. and yielding/behaving
in them.
It definitely slows people down though! And we really
appreciate the reduced traffic! There are still some
speeders but it feels much safer for our kids to play in our
driveway.

Driving More visibility to vehicles
Hi Ryan,
I wanted to add some feedback about the recently
modified vision zero changes to improve turning out of
29th Street onto Glenwood and all the other spots across
Glenwood.
Overall, great idea and think it's a good idea to make some
modifications to increase the safety while turning out of
these streets.
However, I believe the current implementation on 29th
Street has gone a bit overboard, because now any
friends/family that visit my unit in the Glenwood gardens
off 29th/Glenwood have a very difficult time finding any
legal parking.
Between the many parking spots removed from the blind
spot protection PLUS the additional parking spots
permanently reserved for the speed trap vehicles, there are
very few spots available which aggravates any visitors.
My feedback would be, try to design/minimize the reserved
blind spot area to ensure a fixed N-number of vehicles can
fit between the reserved area. I also would prefer either:
1. complete removal of the speed violation vehicle spots
2. partial removal of those spots (there are several
between 28th-30th)
3. keeping some/all of the above spots, but allowing
overnight parking of those spots for roommates/visitors

There is an elementary and middle school close to Quince

have encouraged disrespectful drivers to find other routes
to use instead of roaring through the neighborhood going
45+ mph. Drivers are more polite and wave to each other
so there is a more neighborly feeling here. Pedestrians are
meeting and chatting and neighbors seem to be walking
more on Quince then I've ever seen before. Overall it is less

The curb extensions are good; previously, there was nearly
a blind turn off 29th due to parked cars.
However, the pinch points don't seem to have much effect.
My desk overlooks Glenwood and I regularly see cars speed
past. The pp's did not appear to have much effect. And,
they take up a substantial amount of parking. I'd request
that those be removed. Especially if there will also be spots
reserved for traffic enforcement vehicles.

The implementation above appears to increase risk of an

intended goal perhaps low cost speed humps would be a
better choice. These would not have the same negative
impacts as the implication of curb extensions and pinch

We live on Quince Ave and have three kids under 5. Our
daughter goes to preschool on Quince Ave, and we walk
her to and from school every day. We also take family
walks nightly and walk to Lucky's regularly. I work from
home and watch Quince Ave traffic throughout the work
day, as well. We are in desperate need of speed reduction
on this street. The safety of pedestrians, cyclists, and
motorists are at enormous risk.
Cars continue to speed on Quince, but it has been reduced
some by these changes. Cars generally don't seem to slow
down at the intersection at 17th Street even with the bump
out. In addition, cars seems to speed up coming out of the
chicane to where it's extremely noticeable both visually
and by sound. There are also multiple vehicles daily who
drive on the incorrect side of the chicane and the white and
yellow barriers are constantly hit. The yellow barriers with
metal signs on them make an extremely loud noise when
run into by a car or a kid on a skateboard.
In summary, the current speed mitigation has pluses and
minuses. It's not perfect but it is an improvement.
Also, someone dropped a note in all the mailboxes along
Quince asking people to ask the City to remove the speed
mitigation. In addition to being illegal to put something in
mailboxes, this person signed their letter "Your fellow
neighbor" and addressed it to "Quince St Neighbor." I have
a hard time believing that this person lives on Quince,
because they would likely know that it's Quince Ave, not St.
It feels like there is a campaign by people who want to
speed down Quince to remove speed reduction. I beg you
to keep working on a solution.

I also submitted a response about walking, so please refer
to that for general information.
Specifically on driving, there are a few major issues that I
run into regularly:
- Waiting to turn onto 19th from Quince: Cars turning onto
Quince continue to almost run into my car while I wait to
turn (turning wide or when they're coming from the north
or turning tightly when they're coming from the south).
Perhaps painted lines on 19th showing turn lanes would
help.
- Backing into or pulling out of my driveway: the yellow
island on the chicane is in front of our driveway. I prefer to
back into my driveway so that it feels safer to pull out and
so that I can fit into my garage. Cars like to tailgate as I
head into the chicane and in spite of putting on my blinker
and stopping before my driveway, they will block my
progress as I try to back into my driveway. I think this
generally stems from the island in the chicane. It's
confusing to drivers and they don't understand that they
need to wait when there is so much distance between the
two ends.
- Tailgating/not taking turns: At both the pinch points and
the chicane, cars will tailgate cars in front of them instead
of taking turns. Maybe signage about taking turns would
help.

A couple of times, cars tried to pass (or did pass) in the
pinched areas which felt extremely unsafe. Cars do not
share the road well in my experience on Glenwood. With
the 20 mph speed limit, I think it would be reasonable to
allow bikes to use the full lane (with signs and paint
indicators).
I believe car speed did not change in my experience
because there are still two full lanes even at the pinch
points leading drivers to maintain higher speeds.

Between 28th and 30th, from my experience it seems the
actual driving lanes were not made smaller (still a full two
lane road) so cars do not have to slow down to pass each
other at the pinch points. As I live off the road, having
many street parking spots taken for pinch points that didn't
actually pinch was frustrating. I felt minor improvements in
visibility to turn onto Glenwood from 29th street, but cars
were still moving too fast on average to make a difference.

Hi There,
The traffic calming elements on Glenwood Drive (29th-
30th) have only been mildly effective at slowing down
traffic. The curb extensions do not extend far enough into
the street to cause vehicles to hit the brakes and slow
down. I would request that "pinch points" extending into
the lane of traffic be installed on this section to encourage
vehicles to actually slow down. The pinch points on the
west side of Glenwood Drive (Folsom to 28th) appear to be
more effective than what was installed on the 29th-30th
section. Currently, vehicles just continue to fly down
Glenwood and drift over and straddle the middle yellow
line.
Additionally, the curb extensions have robbed residents of
precious on-street guest parking. Glenwood Gardens HOA
(31 units) has no guest parking and the only place for

residents in this area
I think it is wise to reduce street parking around parking lot
pullouts for visibility purposes, but I had not found this area
at all difficult to navigate as a pedestrian prior to the
project and the only impact I have experienced is an
extremely inconvenient reduction in street parking.

Other: I have
experienced
these
obstructions
on Glenwood
between
Folsom and
28th also.
Other: I have not found people speed
in these two areas nor have I seen
vehicle/pedestrian/bike conflicts in
either area. I am uncomfortable with
the obstacles because they impact
visibility. There is no signage, and I
have been trying to figure out what I
am supposed to do with the almost
complete obstruction of the road!!!
I drive by these locations often and have never noticed any
problems with speeding or with pedestrian/vehicle conflict.
I was totally bewildered by what these were and what they
are for. I feel they are likely to CAUSE accidents rather
than prevent accidents. The city has the following for
speed control:
1. Signs with some areas having 20 mph speed limits.
2. Traffic circles.
3. Speed bumps.
4. Camera.
The installation of these Vision Zero things are a complete
waste of taxpayer money. The money for these traffic
mitigation devices should be spent:
1. Paying police officers or designated individuals to
ACTUALLY ENFORCE THE SPEED LIMITS AND
2. Installing more cameras to ticket drivers speeding as
exist on Valmont.
I have lived on Panorama Ave. in Boulder since 1987.
Within the last 10 years traffic circles have been installed at
23rd and Mapleton and 23rd and Pine. I have to use these
most every day. They are a hazard and dangerous. Maybe
1 in 10 drivers going east to west or west to east slows to
15 mph, and they rarely yield to north to south or south to
north-bound vehicles when those drivers have the right of
way. If I am going north or south at either traffic circle and
see another vehicle approaching from the east or the from
the west I stop even when I am already at the traffic circle
and the approaching vehicle is at a distance from the circle.
I DO THIS BECAUSE I DO NOT WANT TO BE HIT!!! I have
never once seen the speed limit or the right-of-way
enforced by anyone so there is absolutely no incentive for
drivers to change their behavior.

Other: see comments below regarding
Quince Ave. intervention
The work at the corner of 19th of Quince is a good idea. It
could be improved by PLEASE cutting down ALL the foliage
in the ditch on the west side of 19th from the SW corner of
Quince and 19th going south. You still have to pull too far
out into 19th too see what is coming from the south going
north (when trees/weeds are in bloom). The pinch points
west of 17th and Quince are making it safer to walk west
on that street. They are at two locations, so by the time
one gets through the second point you are almost at the
sidewalk by Harmony School.
The Formula One course east of 1755 is a failure. It is not
slowing folks down. They speed up before they go through,
honk their horns and practice their cornering skills. I do not
walk east to 19th on that street anymore. The general rule
is to walk into traffic so you can see what is coming and
that intervention has forced traffic even closer to the side
of the street. Perhaps you should consider a pinch point
and one the does not take out all the parking available for
only one residence. Split it up.
Seems to me that this increased traffic stems from the
growth along Broadway in N. Boulder. Folks are navigating
to Iris using 19th rather than Broadway and 19th (and/or
Yarmouth to 19th, etc.. Put in a double turn lane at both
Broadway and 19th and Iris. I have seen 10 cars backed up
waiting to left turn at both intersections. And please don't
tell me that speed bumps can't be used because they slow
emergency vehicles down. The Formula One course will
certainly slow the very few fire trucks that go down this
street even more.

I think these new methods of trying to make streets safer
by slowing cars down in these obstacle courses (the new
plastic poles with reflector lights) is in itself dangerous.
When I first encountered one (I think the 2700 block of
Glenwood) I almost hit a bicyclist crossing because I was
concentrating on not hitting the markers. The worst one is
at the 1800 block on Quince where the obstacle course
directs cars to driving on the left side of the street then
curving around again to the right side. It's confusing to say
the least! On a positive note - the newer speed bumps (that
aren't so high and bumpy) are great. They make me slow
down without being so hard on the suspension. And they
are really great (smooth) for biking!
Also what about snow plows going through these mazes?
How's that going to work?

1) Remove any markers or diversions in the middle of the

Previously there was plenty of room for a car to safely pass

I'm thinking critiques from neighborhoods are a moot point
about city projects - before, during and after! driving and
walking in and out of my driveway; crashing sounds from
vehicles crashing into posts, signs and mailboxes; horns
blasting; vehicles speeding through the obstacle course or
after they are through the turns. The chicane is very
confusing and I'd like to know where else in Boulder this
has been established. The trapezoid pinch points are fine -
I agree with the original plan. The oval appears to have
been added without neighborhood input.

This "median" is an abomination, creating more problems

reduce the width of the median. I've driven this

Other: Vehicles so focused on
navigating the chicane and pinch
points that they're more oblivious to
pedestrians.
I am a teacher at Centennial Middle School, and I live on
Quince and 17th. I frequently walk to and from school.
Also, my go-to route when I run in the mornings starts with
a westward jog on Quince to Broadway, and ends with a
journey from 19th to 17th, again on Quince.
One evening, after working late at school, I was walking
home in the dark. Instead of turning west on Quince to go
directly to my house, I walked up to Redwood, turned west
there, and used the bike path to get back to my house on
Quince. I did this because it's dangerous enough to walk
on Quince now in daylight, but it would be really dangerous
now to walk there at night with the chicane, pinch points,
and curb extensions. As I remarked in a previous question
on this survey, drivers are now so focused on navigating
the obstacles and negotiating with other cars about who
has the right-of-way, they're more oblivious to pedestrians.
On a street with no sidewalks or street lights, that's too
risky for walkers at night.
As a runner, I've noticed that while cars used to be able to
give me a wide berth as they passed, the pinch points and
curb extensions create many narrow places where they
can't allow that extra space anymore. And where
previously the interaction between me and a passing car
involved only the two of us, now those cars are focused
less on me and more on navigating the obstacles in the
street.
These street amendments seem to have slightly reduced
the speed of cars, but they have greatly increased the risk
to pedestrians. The only pinch point that may have some
benefit is at the cross walk between 17th St. and the bike
path That might usefully serve as a buffer between street

I use my bicycle year-round for transportation. I've been
doing so in Boulder for 30+ year. The traffic calming
devices have made bicycling on Mohawk and Aurora
significantly more dangerous.
Specifically:
* Every time the road narrows, I have to merge with traffic.
* When merging with traffic, motor vehicles are
upset/impatient, and let me know it by honking, following
too closely, etc.
* When the road widens, motor vehicles accelerate to go
around me, going much faster than they ever did before
these "calming" devices were installed.
* More of the road is not plowed during storms, resulting in
more icy patches.
* More of the road cannot be maintained by street
sweepers, leaving more road hazards.
* On Mohawk, something (snowplow? car?) took out a
bunch of pylons. The bases of those pylons (and their bolts)
are still in the street, where they have become road
hazards. I almost went down when I hit one today, with a
car behind me!

I live at 1755 Quince Ave. Please start by taking down the
mess you have created just east of my house. I walk this
street at least twice daily. The situation is that now there is
very little room for pedestrians, as it is a one lane street
where the device is installed. I am very tired of getting
herded into the ditch by traffic which, by the way, is not
slowing down. Cars speed up going through it, honk their
horns, drive on the other side of the street, speed up after
attempting to navigate it. I would like to know if there are
other streets where you have installed this Formula 1
course. Part of the problem on Quince is that there are no
sidewalks on this street from the 1800 block to 15th street.
I would like one of the managers from the city to contact
me at this email address or at (303)440-0653. I will arrange
a meeting with affected citizens, and we can walk down
this street together. If this project continues and the city
puts in permanent curbs (Like on Upland) you will have
created an even more dangerous situation for pedestrians,
as there will be less room to wall on this section of the
street (which does not have sidewalks. I am going to send
an email to both supervisors of this project. I expect a
response by the end of this week (3/11/2022). If no
response, I am going to wok my way up the supervisory
chain, to include the City Manager.
I did just submit comments on the Quince Ave.

Hello! We know that some neighbors are unhappy with the
VZIP improvements installed on Quince. We've been very
happy with how they have worked. Neighbors have
worried about trucks and emergency vehicle access - we've
seen large semi trucks as well as fire trucks navigate
through the improvements just fine. We have heard some
neighbors have concerns about pedestrian safety since the
improvements were installed. I don't understand this
because it cannot be any worse than when there were no
improvements at all. At least peds can now walk inside the
improvements giving some sense of boundary between
vehicles and themselves.
We are especially happy about the widened curb at 19th &
Quince. We live on the corner there and it has been a
major improvement as we have driven vehicles and as
observers of that corner. It is so.much.better.

Other: It caught me by surprise as I
hadn't seen it before. As I got used to
it, I felt it was a very good idea to
make people slow down and pay
more attention.
I am VERY interested in looking into installing the Vision
Zero Innovation Program at the busy corner of Darley and
Toedtli in Table Mesa. Nothing I've seen implemented
anywhere so far other than speed humps, have made
people slow down and become more aware, especially, of
bicyclists and pedestrians. I believe something like this
would address the problems of cars speeding through our
intersection and bicycle safety.

I know those white sticks were installed to slow down cars.
But, for the second time I was almost hit by a car when we
both had to change direction to navigate the sticks on
Glenwood drive west of 28th street. The driver wasn’t
going more than 20mph. The problem was those sticks. I
feel they are a real danger to cyclists wherever they are
installed. If a car is parked before them, a cyclist has no
options but to enter the traffic lane.
And, the sticks eliminate so much street parking. If you
have ever tried to turn right on Glenwood after leaving
Safeway, there is no way you can avoid the oncoming
traffic lane as you turn.
So many of the changes you all have initiated are helping,
but these, I am afraid, are going to cause severe injury.
Please review this part of the program.
Thanks for your time.

Other: These are confusing and
ridiculous. Quince is one of two
arteries to the ONLY local grocery
store in North Boulder. If a grocery
store had been built in the Holiday
Neighborhood, then shutting down
Quince might have been feasible, but
Boulder missed an opportunity to
make North Boulder truly walkable by
not building another grocery store in
the Holiday Neighborhood.

Hi,
I live at Orchard and 19th and drive, run, walk and cycle in
the neighborhood and have been for over 10 years. I just
drove down Quince and was hoping those lines you all
drew in were just for construction and temporary. I see
now they are permanent. You are creating a huge mess on
the street and it is not going to be safer for anyone. Look at
the next-door thread - why did you all think this was a good
idea on a well traveled street? You are only going to force
traffic onto the other side streets, many of which do not
have sidewalks. That along is going to make the
neighborhood incredibly unsafe.

Cars need to have a dedicated lane. Use speed bumps or
speed dips as needed, teh one on Quince already works. I
live at Orchard and 19th and now will be using side streets
that I normally walk and bike on to drive. Kids walk in the
neighborhood as a bus from Dawson drops them off at
Quince and 15th and kids from Centennial walk to Lucky's.
Everyone knows to walk on teh side streets that cars avoid.
I don't mind speed bumps, but this obstacle course with
yielding is a problem. Cars don't want to yield for each
other, they want a designated lane to drive on. I truly
believe you can achieve the same goal with speed bumps
or more stop signs.
Amy,
I did file a comment with the link you sent me, but for some
additional feedback:
1. My son’s bus can no longer drive on Quince because of
the maze that was set up this is problematic as they now
