19th Street Multimodal Improvements Project
Anticipated Project Schedule
2017 - 2019 - Project Planning and Design, Community Engagement
2020 - Early 2021 - Design and Permitting
Mid/Late 2021 - Construction to begin and is anticipated to take 6-9 months to complete
Selected Alternative: Concept 4
On Nov. 21, 2019, the project team hosted an open house, with 78 people in attendance, to share the five conceptual design alternatives being considered for the project and asked for the community’s feedback on a preferred alternative and reasons for that preference. There was a comment form available at the open house and online The goal was to learn which option was preferred so we can balance the needs of the community and meet the goals of the Transportation Master Plan. Your input was utilized as a final concept is selected.
Thanks to all who provided their input on the 19th Street Multimodal Improvement Project! We received a total of 58 completed comment forms. Whether you completed it at the open house on November 21, or provided it online, we appreciate your feedback.
Both the meeting comment forms and the online comment forms expressed a preference for Alternative 4 which includes a combination of attached and detached sidewalks and buffered bike lanes. Read the Community and Environmental Assessment Process report (CEAP) CEAP .
Concept Alternative 4
Feb. 10, 2020 Transportation Advisory Board (TAB) meeting, 6 p.m., City Council Chambers, 1777 Broadway. There will be a public hearing and the board will consider a staff recommendation on the project's community and environmental assessment process. You are invited to participate and share your thoughts

19th Street from Norwood to Sumac avenues is an important multimodal travel corridor in north Boulder. Currently, there is an on-street bikeable shoulder and an existing sidewalk on the east side. These were constructed in the 1990s but the sidewalk does not meet current city design standards. The on-street bikeable shoulder ends at Violet Avenue and is then a designated bike route from Violet Avenue north to Yarmouth Avenue. On the west side of 19th Street, the sidewalk is not continuous from Yarmouth to Norwood avenues.
19th Street from Norwood to Yarmouth avenues has been given a high priority on the city's Missing Sidewalk Links program. The Missing Sidewalk Links program identifies, prioritizes and constructs missing sidewalk segments to provide a continuous pedestrian network and ensure a safe walking environment.
In 2014, the city submitted an application for federal funding to construct a 5-foot-wide sidewalk, install curb and gutter on the east side and complete the missing sidewalk links on the west side of this corridor. The project received funding from the Colorado Department of Transportation (CDOT) Transportation Alternatives program (TAP) and the Federal Highway Administration's Safe Routes to School grant program for the estimated project costs.
The city is also planning improvements along Fourmile Canyon Creek to improve safety and accessibility to Crest View Elementary School by completing an underpass at 19th Street and Fourmile Canyon Creek. The two project teams are coordinating efforts.
The Boulder Valley School District (BVSD) anticipates construction of bond funded improvements to Crest View Elementary School in summer 2020. The city will coordinate with BVSD through planning and design on each of these projects.
Further exploration of the Wonderland Creek floodplain was conducted from late fall 2018 through summer 2019 to understand expectations for achieving the floodplain development permit requirements. Two additional alternatives were included in the project's Community and Environmental Assessment Process (CEAP) to meet the identified facility type for 19th Street through the Low-Stress Walk and Bike Network Plan and to address Transportation Advisory Board feedback provided in August 2018. All design alternatives also now incorporate the features needed to meet floodplain mitigation requirements.
Photos of existing conditions
From Norwood to Sumac on both the east and west sides of 19th Street:
- Install continuous sidewalks, curb and gutter on both sides of 19th Street from Norwood to Sumac avenues
- Convert the existing bikeable shoulders to an on-street bike lane facility Note: On-street parking will not be permitted with the transition from a bikeable shoulder to a bicycle lane with the addition of curb and gutter.
- Upgrade or install pedestrian curb ramps
- Plant new landscaping and trees to replace trees that will be removed in conjunction with this project
- Install a new storm sewer pipe and drainage inlets from Sumac Avenue to Wonderland Creek
- Replace existing Wonderland Creek culvert with a 24 foot-wide by 4 foot-high culvert to meet floodplain development permit requirements
- Bus stop improvements
- Traffic calming and a reduction of the posted speed limit from 30mph to 25 mph.
The speed mitigation devices being considered for the project include speed cushions, raised crosswalks, medians, curb bulb-outs, traffic circles and radar feedback signs. The project will also install enhanced pedestrian crossings where city guidelines identify them to be appropriate. All enhanced crossings installed through the project will include adequate street lighting and signage (State Law—Yield to Pedestrian).
From Sumac to Yarmouth:
- Plan for future multimodal improvements for when funding becomes available
Community and Environmental Assessment Process
During the city's annual capital improvements budgeting process, an interdepartmental team identified the 19th Street project to utilize the city’s Community and Environmental Assessment Process (CEAP). The CEAP is a formal review process to consider the impacts of public development projects. The purpose of the CEAP is to assess potential impacts of conceptual project alternatives in order to inform the selection and refinement of a recommended conceptual design alternative. The CEAP provides the opportunity to balance multiple community goals in the design of a capital project by assessing a project against the policies outlined in the Boulder Valley Comprehensive Plan, the Transportation Master Plan, departmental master plans, and sub-community or area plans (if applicable). The CEAP also ensures that environmental, social and fiscal impacts of projects are minimized and assures compliance with city policies, plans and regulations.
The final CEAP for the 19th Street project will be reviewed and provided official recommendation by the City of Boulder CEAP Review Group, the city's Transportation Advisory Board and City Council.
Previous Community Engagement Events
The city held a second open house on Thursday, April 19, 2018, for the public to view project alternatives, provide feedback and inform the selection of the preferred design. An online questionnaire was also open until May 14, 2018. Review the materials presented on April 19 here and comments received from the public through the open house, emails and online comment form between April 19 and May 14, 2018 here .
The project team attended the Community Cycles Advocacy Committee meeting on Feb. 5, 2018, to better understand their comments submitted through the "A Vision for 19th Street" report.
The project team participated in a WTS-Centennial Middle School Transit Study field trip with Centennial students on Jan. 23, 2018, to better understand their perception and use of transit. The field trip traveled from Centennial along Norwood Avenue to the transit stops at Norwood Avenue and 19th Street.
The project team hosted two site walks on Wednesday, Sept. 27, and Thursday, Sept. 28, 2017, to learn more about the project area and gather ideas for multimodal improvements. Read a summary of comments received from those who joined the site walks here .
The project was featured at the May 22, 2017, North Boulder Public Works Open House. You can review materials and review the draft summary of comments received from the public at the open house here .
