19th Street Multimodal Improvements Project

Project Update

The 19th Street project team presented one step of the project preferred design alternative selection process, the Community and Environmental Assessment Process (CEAP), to the city's Transportation Advisory Board (TAB) on Monday, Aug. 13. Review the TAB meeting notes. pdf

After reviewing and incorporating feedback from the board, and reviewing preliminary floodplain analysis, the project team will finalize the CEAP--including settling on the preferred design alternative. This is a big step. We will share how and why we came to that decision with the public through the project webpage and email list.  

A second meeting with the TAB will take place sometime this fall or early winter.  The board will be asked to provide official review and recommendation of the CEAP, and the team's decision on the preferred design alternative, to City Council.

The CEAP will then be sent to City Council for potential call up following receipt of TAB's review and recommendation--likely in late fall or winter.  If not called up, the preliminary design process begins. Part of the preliminary design process includes meeting with adjacent property owners to discuss the details of the design and impacts to their properties. 

The Transportation Advisory Board and City Council meetings are public meetings. Your participation is both welcome and encouraged.

Project Background

19th Street from Norwood to Sumac avenues is an important multimodal travel corridor in north Boulder. Currently, there is an on-street bicycle lane and an existing sidewalk on the east side. These were constructed in the 1990s but the sidewalk no longer meets current city design standards. The on-street bicycle lane ends at Violet Avenue, but 19th Street is 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. 

Because of the mix of sidewalk conditions, 19th Street from Norwood to Yarmouth was 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 also 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 new transportation connections in the area and mitigating potential flood impacts from Fourmile Canyon Creek. The 19th Street and Fourmile project teams will coordinate efforts.

The Boulder Valley School District (BVSD) will begin planning and design for bond improvements to Crest View Elementary School in spring 2018. The city will coordinate with BVSD through planning and design on each of these projects. 

Project Improvements

From Norwood to Sumac on both the east and west sides of 19th Street:

  • Build sidewalks, where none exist
  • Improve existing sidewalks
  • Ensure curb ramps at each intersection and transit stops are compliant with Americans with Disabilities Act requirements

Improving and adding sidewalk includes building curb and gutter, which creates the opportunity to improve the on-street bicycle lanes and transit stops.

Proposed bicycle lanes will be on-street and 5-foot-wide, excluding gutter, with associated signage and striping. Note: On-street parking will be removed with the transition from a bikeable shoulder to a bicycle lane with the addition of curb and gutter.

The project will also install speed mitigation and enhanced pedestrian crossings where city guidelines identify them to be appropriate. The speed mitigation devices being considered for the project include speed cushions, raised crosswalks, medians, curb bulb-outs, traffic circles and radar feedback signs.  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 selected 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 preferred 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.

Existing Conditions

Previous Public 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. Review the materials presented on April 19 here pdf and comments received from the public through the open house, emails and online comment form between April 19 and May 14, here pdf.

  • 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 pdf. Missed the site walk but have ideas to share? Provide feedback here.

  • The project was featured at the May 22, 2017, North Boulder Public Works Open House. You can review materials pdf, provide feedback here and review the draft summary of comments received from the public at the open house here docx.
