AGENDA ITEM
MEETING DATE: April 08, 2024
AGENDA TITLE: Staff briefing and TAB feedback regarding the Core Arterial
Network (CAN)
STAFF:
Natalie Stiffler, Director of Transportation and Mobility
Valerie Watson, Deputy Director of Transportation and Mobility
Stephen Rijo, Transportation Planning Manager
Melanie Sloan, Principal Project Manager
EXECUTIVE SUMMARY:
This memorandum provides an update on the significant progress made on the Core Arterial
Network (CAN), a top 10 council priority since January 2022. This briefing provides an update
of progress since discussion in July 2023, including on the overall CAN initiative, Priority
Corridor progress, current work and funding plans, and next steps for the initiative, as well as a
request for Transportation Advisory Board (TAB) feedback.
BACKGROUND:
As detailed in the April 11, 2022, and October 10, 2022, memoranda, and July 10, 2023
presentation to TAB, there is a strong rationale for focusing the city’s resources on the Core
Arterial Network (CAN). While arterials make up only 17% of streets within the city, findings
from the Vision Zero Boulder: Safe Streets Report (SSR) show that citywide 67% of total
crashes resulting in serious injury or fatality occur on arterials. In response, Boulder City
Council, in partnership with the Transportation Advisory Board (TAB) elevated work on the
CAN as one of its ten priorities for city department efforts. The CAN is the connected system of
protected bicycle lanes, intersection enhancements, pedestrian facilities, and transit facility
upgrades that will help reduce the potential for severe crashes and make it more comfortable and
convenient for people to get where they need to go along Boulder’s main corridors. The city also
developed the 2023—2027 Vision Zero Action Plan (VZAP) to respond to the findings of the
SSR. The VZAP contains a series of actions that the city will take over the next five years to
reduce the number of traffic-related fatalities and serious injuries to zero. One action is to
implement capital projects on high priority CAN corridors. A total of 13 corridors and associated
street segments identified in the CAN form a prioritized subset of the Transportation & Mobility
Department’s work plan over the next 5 years. (Attachment A).

Council emphasized the need to “be bold” and to accelerate progress on CAN project
development, design, community engagement, and implementation. Subsequently, staff
developed an overall CAN initiative work plan and schedule. Attachment B shows the most up-
to-date schedule and reflects substantial progress on design and project development efforts and
the result of successful grant funding pursuits for CAN corridors.
Staff offer this memorandum to update TAB on overall initiative activities and solicit TAB
feedback on overall CAN initiative and Priority Corridor progress, CAN work plan schedule, and
funding strategy.
ANALYSIS:
The CAN initiative remains on track with 18 projects on 9 of the 13 CAN corridors having
funding or being active in planning, design, and/or construction in 2024 (Figure 1).
Since we last updated TAB at the July 2023 meeting, staff have the following overall CAN
progress summary to report:
• Baseline Road (30th Street to Foothills Parkway) Priority Corridor
o Phase 1 improvements, including repaving, installing an interim protected
intersection, and building the first concrete tall curbs in the U.S. to protect bike
lanes, was completed in October 2023.
o Phase 2 planning and design, which will build more significant improvements on
Baseline Road with external grant funds, begins community engagement in mid-
April 2024 with walk and bike rides with community members and partners.
• Iris Avenue (Broadway to 28th Street) Priority Corridor
o In 2023, the project focused on data collection and community engagement,
hosting 27 engagement activities that reached over 1,600 people and garnered
more than 2,100 comments by year end.
o Design work began in early 2024 to advance the overall design process, develop
design alternatives that respond to the identified issues and opportunities, and to
advance the VZAP.
o An open house is being planned for late April followed by additional engagement
events to ask the community to provide their feedback on conceptual designs and
key tradeoffs that may be needed to achieve CAN and project goals.
o An update to city council is scheduled for June 6, 2024.
• 13th Street Neighborhood GreenStreet – enhanced crossing at 15th Street and Iris Avenue
o Completed contracting and will begin construction of a new pedestrian median
and pedestrian signal and improve bike connections to the crossing in May; the
work will take about one month to complete.
• 28th Street Improvement Project (Canyon Boulevard to Iris Avenue)
o Began utility relocation work in fall 2023 in preparation for the start of
construction of multi-use paths and Business-Access-Transit lanes later this year.
• 30th Street Preliminary Design (CO 119/Diagonal Highway to CO 7/Arapahoe Ave)
o Consultant selected to support the preliminary design for the project with
contracting to be completed in April and community engagement to begin later
04.08.24 TAB Agenda 8 - CAN Update

this spring with a youth walk audit led by partners Growing Up Boulder and the
Family Learning Center.
• 30th Street Protected Bike Lanes (Arapahoe Avenue to Colorado Avenue)
o Completed contracting and is beginning construction in April to continue
protected bike lanes north to Arapahoe Avenue from the recently completed 30th
Street and Colorado Avenue protected intersection.
• Broadway Transit Improvements (Table Mesa Drive to Regent Drive)
o Design began in 2024 after receipt of DROG TIP funds and will continue through
this winter, with construction of intersection improvements and completion of a
Business-Access-Transit feasibility study to follow in 2025.
• Colorado Avenue and 28th Street Protected Intersection
o Began construction of the city’s second fully protected intersection in winter 2023
with work anticipated to finish later this spring.
• East Arapahoe Avenue Multi-use Path and Transit Stops Project (Foothills Parkway to
Cherryvale Road)
o Utilities work began in winter 2023 with construction of multi-use path and bus
stop improvements to follow, beginning in winter 2024 and completing in late
spring 2025.
ACTIVE PROJECTS ALONG THE CORE ARTERIAL NETWORK (CAN)
Priority Corridor Update
There are three CAN Priority Corridors: Baseline Road, Iris Avenue, and Folsom Street. These
were selected for their value to the network in terms of providing enhanced multimodal north-
south and east-west connectivity currently lacking in those areas of the city, the opportunity to
couple improvements with scheduled pavement resurfacing, and the ability to advance VZAP
actions to reduce severe injury crashes on these key High Risk Network (HRN) corridors. The
HRN is a network of streets in the city that features the most contextual factors associated with
fatal and serious injury crashes (Figure 2). Measured by crashes per vehicle miles traveled, the
HRN has roughly five times more risk than all of Boulder’s arterial streets combined. Managing
risk and mitigating crashes on this small percentage of streets can have an outsized impact on
reducing fatal and serious injury crashes.
Baseline Road Priority Corridor
Work on the first Priority Corridor, Baseline Road from 28th Street to Foothills Parkway, began
in 2022. The Baseline Road Priority Corridor is one of the most-traveled east-west corridors in
the city and is home to many key community destinations and services, including affordable
housing, grocery stores, shops, health centers, and student housing for the University of
Colorado Boulder. It connects residents, students, and employees and serves regional transit for
East Boulder and Boulder County.
The SSR identified this section of Baseline Road as one of the top 10 crash locations for people
walking and bicycling in the city, the VZAP identified it as part of the HRN, and the Denver
Regional Council of Government's (DRCOG) identified it as part of the Regional High Injury
04.08.24 TAB Agenda 8 - CAN Update

Network as a Critical Corridor. Baseline was identified as a CAN Priority Corridor because of
these findings.

Baseline was identified as the first Priority Corridor because it could be phased: Phase 1 used
local dollars and leveraged planned Pavement Management Program (PMP) pavement
resurfacing to gain the safety benefits of strategic, prioritized location improvements now while
the city awaited the distribution of DRCOG 2022-2025 TIP funds in the first quarter of 2024.
After 12 months of design and community engagement, implementation of Phase 1 changes to
Baseline Road were completed in October 2023. Changes included the first use of concrete “tall
curbs” in the United States and incorporation of public art by local artist Talia Parsell (Figure 3
and Figure 4). This approach is a model for the project development process for Priority Corridor
efforts on Iris Avenue and Folsom Street as it enables staff to expedite projects from design to
implementation as quickly as possible.
Figure 3: Tall Curb Protected Bike Lane Featuring the Work of Local Artist Talia Parsell
To augment the city’s limited local dollars, the department pursued competitive external grant
funding to bring more permanent, capital-intensive improvements to the Baseline Road corridor
for Phase 2 of the CAN Priority Corridor effort. DRCOG Transportation Improvement Program
(TIP) grant funds of $3.1 million awarded in 2023 became available in early 2024. These funds
initiated Baseline Phase 2. Phase 2 includes design and engagement to support comprehensive
implementation of multimodal, capital-intensive improvements, such as completing the bike lane
and intersection protection provided with roadway repaving in Phase 1, additional pedestrian and
protected intersection enhancements, and transit efficiency improvements.

Key stakeholder engagement will begin mid-April with walking and biking tours. This second
phase of engagement will inform the design process and build off the following themes heard in
the first phase of work:
• High speeds and amount of vehicular travel along the corridor
• Drivers turning on/off the corridor feel unsafe due to high speeds on Baseline Road
• Perceived lack of safety and comfort for people bicycling in the existing protected
bicycle lanes that are demarcated with flexible delineators
• Conflicts between people bicycling and buses accessing the curb for passengers
• People walking and rolling want more and safer crossings that provide enough time to
cross the street and provide enough space for them and for micromobility users
• Sidewalks need repairs in some locations
• Difficulty connecting to/from surrounding infrastructure for people walking and
bicycling from or along Baseline Road
• Noise and lack of comfort walking along the corridor or waiting for the bus
• Lack of amenities at transit stops, such as shelters, benches, trash facilities, secure
bicycle parking, and visibility due to vegetation growth
• Poor pavement condition within the roadway, bicycle lanes, and crosswalks
Conceptual designs will be informed by community engagement, concurrent data collection and
traffic analysis, and the VZAP. Additionally, staff will coordinate design with separate, related,
and concurrent efforts funded under the Highway Safety Improvement Program (HSIP), the
Colorado Safe Routes to School (SRTS) grant program, and the city’s pavement management
program:
• Realigned crossing and pedestrian signal at Baseline Road and Canyon Creek Road
• Signal upgrades at Baseline Road and Mohawk Drive
• Creating safer routes for Manhattan Middle School students and the Manhattan
Neighborhood on Manhattan Drive from Baseline Road south to Iroquois Drive
• Re-Paving Baseline Road from Foothills Parkway to Cherryvale Road
Baseline Road Phase 2 designs will be shared with the community to receive their feedback in
summer 2024. This input will inform the final design, which is anticipated to be completed in fall
2024. Work to prepare the Phase 2 project for construction will continue into 2025. Construction
is anticipated to begin mid-year 2025 and take 12 months to complete.
Iris Avenue Priority Corridor
Work on the second Priority Corridor, Iris Avenue from 28th Street to Broadway, began in
summer 2023. Iris Avenue is an important east-west corridor in north Boulder that provides
direct, convenient connections to everyday neighborhood destinations and supports travel within
Boulder and between Boulder and communities along the Diagonal Highway (Figure 5).
04.08.24 TAB Agenda 8 - CAN Update
Page 9 of 24
Figure 5: Iris Avenue Priority Corridor Project Limits
04.08.24 TAB Agenda 8 - CAN Update
Page 10 of 24
The CO 119 Safety, Mobility and Bikeway Project will bring regional multimodal transportation
improvements, including bus rapid transit and off-street multi-use path connections, to the
eastern edge of the project corridor. Construction is scheduled to start on this project in 2024 and
be completed in spring 2027.
The SSR found crashes occurring at each of the major intersections on the corridor with serious
injury crashes at the Broadway and 28th Street intersections, the VZAP identified Iris Avenue
from 19th Street to 28th Street as part of the HRN, and the city’s Low Stress Walk and Bike
Network Plan (2019) calls for greater vertical separation and protection between vehicle and
bicycle lanes on Iris Avenue and the need for pedestrian improvements in key areas.
These projects and plans demonstrate the important role Iris Avenue serves in the city and
regional transportation networks and why this corridor was selected as the second Priority
Corridor.
In 2023 the city focused its efforts on data collection and community engagement by hosting 27
engagement activities that reached over 1,600 people and garnered more than 2,100 comments.
Community engagement is an integral part of the overall project development process with
feedback from the community on existing conditions, challenges, and opportunities informing
the design process. Community partners helped broaden the reach and quality of engagement
through walk audits, Spanish-language and older adult-focused engagement activities,
bikeabouts, accessible roll and strolls, conversations with business owners and operators, and
pop-ups at important community destinations including Safeway, Columbine and Foothills
elementary schools, transit stops, and Growing Gardens (Figure 6).
Figure 6: Iris Avenue Priority Corridor Engagement In 2023
04.08.24 TAB Agenda 8 - CAN Update
Page 11 of 24
Themes heard from the 2023 community engagement are:
• East-west travel is important, and drivers appreciate Iris Avenue as a convenient and
reliable route across the city
• People walking, rolling, biking, and taking transit also want Iris Avenue to provide
convenient and safe routes
• Sidewalks could be improved to provide comfort, safety, and attractive walking
conditions. Sidewalks are currently not wide enough, winding, sloping, bumpy, and often
blocked by overgrown vegetation
• Crossing Iris Avenue safely and conveniently is a priority for people of all ages and
abilities traveling to school, work, for errands, and for recreation – but today some see it
as a barrier to getting where they want to go
• Vehicles travel at high speeds, creating unsafe conditions and excessive street noise
• Safer neighborhood and business access is essential
• Drivers feel unsafe turning onto and off Iris Avenue and feel they’re more likely to crash
with oncoming traffic when doing so
• Delivery, transit, waste management and other vehicles stop in-lane, blocking the bike
and right-side travel lanes
• Residents are concerned changes will impact emergency evacuation and response
• Neighbors want to maintain the character of their neighborhoods, which they see as
providing safer, more comfortable alternatives for walking, rolling, and biking than
arterial streets like Iris Avenue, and they are concerned that changes to Iris Avenue could
create traffic diversion onto nearby streets
• Community members want attractive facilities and opportunities for placemaking
• Better wayfinding and help navigating to local and regional destinations are desired
• Roadway pavement conditions could be improved
• Transit service is infrequent, and many transit stops are not accessible and lack shelters,
benches, and trash cans
Data collection and analysis occurred concurrent with engagement throughout 2023. Data
included the number and speed of vehicles on Iris Avenue and nearby neighborhood streets, the
number of people biking on Iris Avenue, and the number of people walking and biking across
Iris Avenue on a typical day, among other information.
The engagement themes, data collection and analysis provided understanding of the existing
conditions on Iris Avenue and helped identify issues and opportunities for improvement. Design
work began in early 2024 to advance the overall design process, develop alternatives that
respond to the identified issues and opportunities, and to advance the VZAP.
The community will be asked to provide their feedback on conceptual designs and key tradeoffs
that may be needed to achieve CAN and the project goals beginning in late April 2024 through
in-person and online open houses and at additional engagement events being planned through
early summer.
Following this engagement, a design recommendation will be brought to this board and the
Planning Board through a Community and Environmental Assessment Process (CEAP). Both
04.08.24 TAB Agenda 8 - CAN Update
Page 12 of 24
boards will be asked to make a recommendation on the CEAP to City Council for them to take
action on the recommended design. These public meetings are slated for Summer 2024.
The City Council approved design will be implemented as funding is secured.
Folsom Street Priority Corridor
The Folsom Street Multimodal Improvements Project from Pine Street to Colorado Avenue is
the third CAN Priority Corridor (Figure 7). Folsom Street is an important north-south corridor in
central Boulder. It connects homes, office spaces, restaurants, shops, grocery stores, parks, and
CU’s main campus to each other and the city’s transportation network for walking, biking,
driving, and taking transit.
The SSR found between 2015 and 2019 the corridor had 253 crashes, eight of which were
severe, including one fatality, and virtually all involved someone walking or biking, the VZAP
identified most of the corridor is on the HRN (Fremont Street to Taft Drive), and the city’s Low
Stress Walk and Bike Network Plan (2019) calls for greater separation and protection between
vehicle and bicycle lanes and the need for pedestrian improvements in key areas.
The project also has high potential to address racial inequity because many of the almost 28,000
people who live along the corridor are historically underserved: 23% are individuals of color,
40% are in low-income households and 15% are in households with no access to a motor vehicle.
Folsom Street is designated by DRCOG as an Active Transportation Corridor for its potential for
greater non-single occupancy vehicle use if safer connections were implemented. On an average
day, 17,450 vehicles are driven on Folsom Street between Pine Street and Colorado Avenue –
and 4,000 people walk, 1,600 people bike, and 1,125 use transit despite the corridor offering
little physical protection and few amenities for the most vulnerable road users (Figure 8).
The Folsom Priority Corridor provides important access to opportunity and short trip linkages by
providing walkable, bikeable, and transit supportive connections that link to previously
implemented protected bicycle lanes on Folsom Street from Valmont Road to Pine Street as well
as connect to planned improvements on Colorado Avenue.
Conceptual design and community engagement will initiate in early 2025 when DRCOG TIP
funds become available. Depending on project sequencing, the Pavement Management Program
will also bring scheduled pavement resurfacing to the corridor.
Final design and implementation will be advanced as funding is secured.

CURRENT AND FUTURE PROJECTS
Planning & Design
30th Street Complete Street Preliminary Design Between Arapahoe Avenue to the Diagonal
Highway
30th Street between Arapahoe Avenue (CO-7) and Diagonal Highway (CO-119) is a primary
north-south arterial street in Boulder and provides local and regional connections to Boulder
Junction, the University of Colorado-Boulder (CU) East Campus, the 29th Street Mall, and
thousands of residences and jobs. While it is an important multi-modal travel corridor with
20,000 vehicles, 1,109 transit, and 1,700 walk and bike trips in a typical day, the current design
is oriented to facilitating vehicular mobility which creates conflicts between all modes, travel
delays for buses, and a high level of stress for bicyclists and pedestrians (Figure 9).
The SSR identified the 30th Street and CO7/Arapahoe Avenue intersection as one of the top 10
crash locations in the city, the VZAP identified 30th Street from Colorado Avenue to Valmont
Road on the HRN, DRCOG identified 30th Street from Valmont Road to Diagonal Highway
(CO-119) on the Regional High Injury Network and 30th Street from Valmont Road to Arapahoe

Avenue as a Critical Corridor, and the city’s Low Stress Walk and Bike Network Plan (2019)
calls for greater separation and protection between vehicle and bicycle lanes from Pearl Street to
the Diagonal Highway (CO-119) and the need for pedestrian improvements in from Arapahoe
Avenue to Walnut Street and from Valmont Road to the Diagonal Highway (CO-119).
The 30th St Preliminary Design will collect data and conduct collaborative community
engagement to inform a 15% preliminary design for the corridor that provides safe, reliable, and
equitable transportation choices to eliminate serious injury and fatal crashes on the street.
Conceptual design and community engagement will begin in April 2024 with a community
partner led youth walk.
A design recommendation based on community feedback, data and analysis, and plans and
policies will be brought to this board and the Planning Board through a Community and
Environmental Assessment Process (CEAP). Both boards will be asked to make a
recommendation on the CEAP to City Council for them to take action on the recommended
design. These public meetings are anticipated to take place in 2025.
At the end of 2023, the city received a Safe Streets for All federal grant to advance design and
implement improvements on 30th Street between Pearl Street and Diagonal Highway identified
by the VZAP and this project. Additional funds will likely be needed to implement all project
recommendations, and these will be implemented as funding is secured.
30th Street & Arapahoe Avenue Intersection Preliminary Design
The 30th Street & Arapahoe Avenue Intersection Preliminary Design project is at the nexus of
two CAN corridors: 30th Street and Arapahoe Avenue (Figure 10).
The SSR identified the 30th Street and CO7/Arapahoe Avenue intersection as one of the top 10
crash locations in the city, the VZAP identified Arapahoe Avenue as a high priority HRN, and
the city’s Low Stress Walk and Bike Network Plan (2019) calls for greater separation and
protection between vehicle and bicycle lanes as well as for pedestrian improvements.
The intersection is also a high-volume transfer point for transit passengers connecting between
the high-frequency north-south BOUND route on 30th Street and the high-frequency east-west
JUMP route on CO7/Arapahoe Avenue, which provides transit access to east Boulder County
communities. In the future, this will be an even more important regional transit connection as
CO119 BRT (between Boulder and Longmont) and CO7 BRT (between Boulder and I-25) come
into service.
The project will begin preliminary design and engagement activities in winter 2024 and continue
through late summer 2025. Construction will follow in winter 2026. When completed, the project
will extend work currently underway to construct protected bike lanes along 30th Street south of
the intersection and will integrate with design recommendations from the 30th Street Complete
Street Preliminary Design north of Arapahoe Avenue to the Diagonal Highway and the East
Arapahoe Avenue Multimodal Corridor final designs.

The project is funded by Colorado Department of Transportation and local funds, with
implementation funding being provided by the 2023 awarded Safe Streets and Roads for All
federal grant.

East Arapahoe Avenue Preliminary Design from 28th Street to 64th Street
The East Arapahoe Avenue from 28th Street to 64th Street project is a section of segment A in the
CO 7 Multimodal Corridor. Segment A is a critical commuter and business route that connects
the region to Boulder’s core. The project area is commonly known as East Arapahoe, a six-lane
road and one of the most heavily traveled commuter corridors in the city (Figure 11).
Figure 11: East Arapahoe Avenue Preliminary Design from 28th Street to 64th Street Project Limits
The SSR identified Arapahoe Avenue as a top crash corridor, including a fatal crash and many
crashes including people walking and biking, the VZAP identified the corridor as a high priority
HRN, DRCOG identified it as part of the Regional High Injury Network and a Critical Corridor,
and the city’s Low Stress Walk and Bike Network Plan (2019) calls for greater separation and
protection between vehicle and bicycle lanes and the need for pedestrian improvements in key
areas.
Preliminary design for segment A began in 2022 and will be completed in mid-2024. The city
has received some funding to advance final design and implementation for portions of segment
A. The city will continue to pursue additional funding to advance the remaining portions.

FUNDING
Since the establishment of the CAN as a City Council priority in early 2022, $15.6 million in
funding has been awarded for CAN projects through various external grant pursuits. The primary
sources for these funds were the competitive grant programs offered through the Denver
Regional Council of Governments (DRCOG) Transportation Improvement Program (TIP) and
the Colorado Department of Transportation (CDOT) Transportation Alternatives Program
(TAP).
The city recently was awarded over $24 million in federal Safe Streets and Roads for All (SS4A)
funding to implement specific actions from the city’s Vision Zero Action Plan, with many of the
improvements funded by these efforts falling along CAN Corridors.
Additional funds will be needed to implement all CAN corridor recommendations. Staff will
request funds in departmental budget cycles and seek future external grant funding opportunities.
The overall strategy for funding CAN corridor efforts will focus our limited local dollars on
preliminary design, community engagement, and consultant assistance for Priority Corridor and
04.08.24 TAB Agenda 8 - CAN Update
Page 21 of 24
other corridor segments and studies. Funding for final design and construction efforts will
generally be solicited from external grant opportunities due to the significant costs associated
with infrastructure projects. Staff continues to balance the need to enhance our system with the
need to maintain it.
TAB ACTION REQUESTED
Staff requests the Board’s feedback and questions regarding the overall CAN initiative and
Priority Corridor progress, CAN work plan schedule, and funding strategy.
