Denver Urban Waterways Restoration Study



The Denver Urban Waterways Restoration Study is a study to identify restorative improvements to three major urban waterways — Harvard Gulch, Weir Gulch, and the South Platte River from 6th to 58th Avenues — in the City and County of Denver. Based on the availability of newer predictive computer models that can now more accurately determine flood risk and a heightened awareness of ecosystem health, sponsors are conducting a series of studies to reassess the condition of these waterways considering flood risk assessment, ecosystem health, and recreational opportunities.

Study Updates

The study began in 2015 and is scheduled to continue through 2018. After several public meetings in 2015 and 2016, the study team is now preparing a draft of the Feasibility Study, tentatively scheduled for release in 2018.

Following the conclusion of the study, the City will begin work to secure funding for any future design or construction. No construction activity is expected before 2020 at the earliest.

The study is sponsored by the United States Army Corps of Engineers (USACE), Urban Drainage and Flood Control District (UDFCD), City and County of Denver (CCD), and the Colorado Water Conservation Board (CWCB).

Check back for information about the next round of public meetings.
