30th and Colorado Corridors Study

This study is examining existing and future travel conditions and needs and developing design options to improve travel for all modes along 30th Street (Baseline to Pearl) and Colorado Avenue (Foothills Parkway to Broadway/Euclid). The 30th and Colorado Corridors Study began in 2017 and is currently in the design options evaluation phase.

Next Steps

Staff is currently evaluating public feedback on the design options as well as technical considerations to determine a set of recommendations to take back to the community, the Transportation Advisory Board and City Council. The next community meeting will take place during spring 2018 and will share the plan layouts for community feedback. We will post more information about the community meeting once it has been scheduled.

The following meetings have also been scheduled:

  • Community Working Group, March 20, 6 - 8 p.m., Jennie B. Caruthers Building, 3415 Colorado Ave, Room B231
  • Transportation Advisory Board: May 14
  • City Council: May 22 Study Session (note council meeting agendas are subject to change)

Conceptual Design Options

Five options are being considered for each of three corridors within the study. View the summary of all options pdf. An evaluation of each design option can be viewed under each corridor below.

Project Background and Purpose

The City of Boulder and University of Colorado Transportation Master Plans identified the need for detailed studies of several transportation corridors in Boulder, including 30th Street and Colorado Avenue. These corridors provide travel options between key activity centers in Boulder, including the University of Colorado (CU) Housing at Williams Village, CU East Campus, Boulder Junction, 29th Street and CU Main Campus.

The purpose of the study pdf is to examine existing and anticipated transportation conditions and needs, and develop designs to improve travel for all modes for 30th Street from Baseline Road to Pearl Street, and Colorado Avenue from Foothills Parkway to CU Main Campus/ Broadway and Euclid Avenue.

The study area contains six of the top crash locations in Boulder, according to the 2016 Boulder Safe Streets Report. These locations are: 30th-Colorado, 30th-Baseline, 30th-Arapahoe, Colorado-Regent, 30th-Pearl, and Colorado-28th.

The corridors study will integrate with plans for two new underpasses for pedestrians and bicyclists in the study area: 30th and Colorado Underpass and the Foothills Parkway Underpass.

The ­final product of the study will be conceptual design plans for each corridor. The conceptual plans and cost estimate will be used for near and long-term implementation.

Vision, Goals and Objectives and Existing Conditions

 Vision, goals and objectives pdf 

Vision Statement: The 30th Street and Colorado Avenue corridors provide safe, enjoyable, and direct travel for people of all ages and abilities, using all modes of transportation in all weather conditions. As Complete Streets, these vibrant corridors efficiently connect people to neighborhoods, jobs, shopping, parks, schools, the University of Colorado, and the surrounding natural environment.

You can also view additional information on the existing conditions pdf—including walk and bike counts, transit stop ridership, transit routes, collisions, and motor vehicle volume and speed.

Community Engagement

Past Public Meetings

Feb. 7, 2018: Meeting to present and get feedback on the latest information on three projects: 30 th  and Colorado Corridors Study, Foothills Parkway Bicycle and Pedestrian Underpass and the 30  th  and Colorado Bicycle and Pedestrian Underpass. 

Oct. 11, 2017: Citywide open house "What's Up Boulder" featured information about the study, vision, goals and objectives.

Sept. 25, 2017:   Open house to present and get feedback on vision, goals and objectives and conceptual design options. Online questionnaires were available for those who were unable to attend the meeting. Nearly 100 participants joined. A meeting summary including feedback collected pdf is now available.

Feb. 9, 2017:  Open house to share information about the scope of the project and gather community input to develop the study's vision, goals and objectives.

Community Working Group

The project team has formed a Community Working Group (CWG) to provide input and feedback during the planning process for the 30th Street corridor (between Baseline Road and Pearl Street) and the Colorado Avenue corridor (between Foothills Parkway and Broadway at Euclid Avenue). 

The working group includes 16 members, representing broad interests and community perspectives. The group includes the following participants - Alana Wilson, Ann Haebig, Bart Miller, Cindy Kraft, Dave Bacon, David Ensign, Dom Nozzi, Elisabeth Patterson, Ezekiel Dominguez, Jennifer Maria Shriver, Joan Gabriele, Kate Honea, Micah Schwartz, Stavros Roditis, and Teddy Weverka.        

Purpose and Roles of the Community Working Group

The CWG will be an important part of the community engagement process. The CWG will provide input and feedback, from different interests and perspectives, to the city staff team during the planning process. The CWG’s input will help staff explore future transportation improvement options that serve the range of diverse interests and travel needs in the community based on achieving the goals of the Transportation Master Plan. City staff team will use the CWG’s feedback when developing recommendations and materials for consideration at Transportation Advisory Board and City Council meetings.

Specific topics to be discussed by the CWG include: (1) overall corridor study goals and objectives (2) the range of options for transportation improvements, (3) land use and connections (4) the development and analysis of potential corridor design options – including street design, crosswalks, bikeways, transit services, landscaping, identity, lighting, and smart transportation technologies (5) the criteria by which to evaluate corridor alternatives, (6) the analysis of alternative corridor plans and identification of a preferred concept plan, and (7) recommendations for next steps to implement a preferred concept plan for each corridor.  

Community Working Group Meetings

Community Working Group meetings are open to the public and each meeting will include an opportunity for members of the public to offer their comments and feedback.
