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.
The final Integrated Feasibility Report and Environmental Impact Statement (EIS) was released April 2019.
The U.S. Army Corps of Engineers completed three public meetings in summer 2018 to present and receive comment on their recommendations for the South Platte River, Harvard Gulch, and Weir Gulch. The public comment period was open through August 28, 2018.
The Feasibility Study began in May 2014, with the final Integrated Feasibility Report and Environmental Impact Statement (EIS) released in April 2019.
On July 29, 2019, Lt. Gen. Todd T. Semonite, U.S. Army Corps of Engineers Commanding General and 54th U.S. Army Chief of Engineers signed the recommended plan. The document, called the Chief’s Report, moves the project forward to allow it to be eligible for possible future Congressional authorization and appropriation.
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).
