30th and Colorado Corridors Study
This study examined existing and future travel conditions and needs to develop 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 the recommended options for 30th Street and Colorado Avenue are undergoing preliminary engineering and cost estimation. The options for the University of Colorado Boulder section will be further evaluated during CU's TMP update.
Recommended Design Options
Five design options were considered for each of three corridors within the study. View the summary of all options .

View the recommended designs in plan layout for 30th Street and Colorado Avenue below:
- Summer 2018 - mid 2019: Cost estimation, preliminary engineering and phased implementation plan.
- Mid to late 2019: Council to consider acceptance of plan use during review of development projects
- Implementation of individual projects such as 30th and Colorado Underpass and Colorado Avenue and Regent Drive Intersection Safety.
- Implementation of other projects as funding becomes available.
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 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 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 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 —including walk and bike counts, transit stop ridership, transit routes, collisions, and motor vehicle volume and speed.

May 22, 2018: City Council feedback at the Study Session meeting was in support of the recommended designs.
May 14, 2018: Transportation Advisory Board (TAB) to review study analysis and consider recommended options. TAB provided feedback and made a recommendation that City Council approve the recommended options.
May 3, 2018: Staff shared the results of public feedback and the technical analysis for all options and presented plan layouts for the top-performing options for each segment of the corridors. Meeting graphics can be viewed in the Additional Resources section above. Community members were asked to identify what they liked about the options and what concerns they have. Several intersection design options to improve safety were also presented. Community members could also view the latest information for the Foothills Parkway Bicycle and Pedestrian Underpass and the 30th and Colorado Bicycle and Pedestrian Underpass.

Feb. 7, 2018: Meeting to present and get feedback on the latest information on three projects: 30th and Colorado Corridors Study, Foothills Parkway Bicycle and Pedestrian Underpass and the 30th and Colorado Bicycle and Pedestrian Underpass. A summary of all design options for the 30th and Colorado Corridors Study can be found here . An evaluation of the design options for each corridor can be found below:
30th Street Corridor
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 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.
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.
