39th Avenue Greenway & Open Channel

With this project, Denver Public Works will create a new 12-acre recreational greenway with a multi-use trail between Franklin and Steele streets while reducing flood risk to nearby homes and businesses.

The historic Montclair basin is the largest in Denver with no natural drainage. Instead of floodwater flowing through the historic Montclair creek, which was built over in the early 1900s, water runs through neighborhood streets. This project will replace the city's aging infrastructure with green infrastructure that can better control stormwater and improve public safety and water quality. In addition to protecting neighborhoods from damaging floodwaters when storms hit, the greenway will provide other neighborhood benefits that will be enjoyed year-round. The greenway will stay mostly dry, and convey water only in storm events.



Project Update: August 2018

Starting Wednesday, August 15, the City and County of Denver and the SEMA Construction design/build team will temporarily close Franklin Street and sidewalks from 40th Street/E. 39th Avenue to Lafayette Street while crews prepare the area for construction, relocate water, storm and sanitary pipes as well as relocate utilities. The closure will be 7 days a week, 24-hours a day and will be in effect through November 2018. Working hours are 7:00 a.m. to 6:00 p.m., Monday through Saturday.

Detour routes will be posted and business access will be maintained.
