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. Learn more on the Fourmile Canyon Creek webpage. The two project teams are coordinating efforts.
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.
