Fourmile Canyon Creek Greenways Improvements Project

Fourmile Canyon Creek Greenways Improvements Project

The city is 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.

This project includes creek channel improvements, construction of a multi-use path connection between 19th Street and Broadway and the replacement of two structurally deficient bridges at Violet Avenue and Upland Avenue with bicycle/pedestrian underpasses that also serve a flood benefit. The project provides a missing link in the path system, with safer access to Crest View Elementary School for pedestrians and bicyclists.

Project Schedule and Next Steps 

On June 21, 2016, the Final CEAP Upland to Broadway pdf document was approved by City Council. Preliminary design is currently underway, and final design is anticipated to be completed by the end of 2018, with a 2-year construction period to follow. Funding for transportation components of the project will come from the 2017 Community, Culture and Safety Tax extension. 

19th to 22nd Street Underpass Design

The Greenways Project on Fourmile Canyon Creek from 19th to 22nd Streets is intended to improve flood conveyance as well as safety and accessibility to Crest View Elementary School. A Community and Environmental Assessment Process (CEAP) for Fourmile Canyon Creek east of 19th Street was completed in March 2012 and the city has hired a consultant to complete a design for the improvements for this area.

West of 19th Street Path and Flood Mitigation Alternatives Analysis

The City completed a Community and Environmental Assessment exploring flood mitigation and trail options for the upstream reach from Upland Avenue through Violet Park to the west of town. The purpose of the CEAP process was to evaluate the various alternatives available. 

Upcoming Meetings

The project is currently in its design phase, and no upcoming events are currently planned.

Previous Meetings

May 22, 2016 - North Boulder Public Works Open House

November 18, 2015 - Open House at Crest View Elementary to present:

  • Updated information on the design for the multi-use path and underpass between 19th and Tamarack Street,
  • Path Connector Alternatives and seek community feedback, and
  • CEAP alternatives for the area west of 19th Street and seek community feedback.

Sept. 26, 2013 - Fourmile Canyon Creek Open House

This open house was originally scheduled before the September 2013 flood as part of a CEAP to evaluate flood mitigation, path connection, and park development options for the area along Fourmile Canyon Creek between Upland Avenue and Violet Park.

City staff expanded the purpose of this open house to provide an opportunity for the community to discuss the impacts of the recent flooding, see the flood damage information that had been collected, and provide comments about future improvements. This was also an opportunity for residents to speak with city staff to get information and assistance with flood recovery. Development options for Violet Park will be presented at a future meeting.

Feb. 15, 2012 - GAC Meeting

The Fourmile Canyon Creek 19 th - 22 nd Streets CEAP was discussed and reviewed by the Greenways Advisory Committee (GAC) at their meeting on Feb. 15, 2012.

Oct. 26, 2011 - Open House

The public was invited to provide input on:

  • Pedestrian, bicycle and vehicular access connections in the area between 22 nd Street and Crest View Elementary School and Upland and Riverside Avenues; and
  • Flood mitigation improvements at 19 th Street and Fourmile Canyon Creek.

Public input received at the May 2011 Open House helped develop several alternatives for consideration. City staff presented updated information on the alternatives, concept-level costs, and potential impacts and benefits of the alternatives.

May 11, 2011 - Open House Presentation

A public Open House was held on May 11, 2011 to kick off the CEAP and obtain community input on potential access options. Proposed pedestrian, bicycle and vehicular access connections as shown in the Transportation Master Plan, Greenways Master Plan and North Boulder Subcommunity Plan were available for review and comments. Information about proposed flood improvements at 19 th Street and Fourmile Canyon Creek was also available.
