The Feasibility Study review and approval process will take 4-5 years to complete. The Study began in May 2014 and will be complete by approximately the end of 2018.
Public input was received during the initial scoping period in Spring of 2015. USACE and the City and County of Denver developed a variety of conceptual solutions (also called alternative plans) during the Summer and Fall of 2015. Additional public input on the conceptual alternative plans was gathered in Jan/Feb of 2016.
USACE is currently evaluating and comparing the alternative plans based on several factors, including the benefits and costs of each waterway. Once that analysis is complete, a draft feasibility report was released in July 2018. An additional round of public meetings was held during the comment period following the release of the draft report.
After the public and agency comment period on the draft report, all comments received will be considered, and a final feasibility report will be completed near the end of 2018. If the feasibility study is approved, a Chief of Engineers’ Report will be completed and transmitted to Congress for authorization in 2019.
After the completion of the Chief of Engineers’ Report in 2019, the project sponsors will then begin to seek funding for the design and construction of improvements based on the recommended plan. The costs to solve the issues are significant and could take many years to fully implement.
The current study phase is expected to last 3 years, to be completed in 2017. Securing funding for implementation would take a minimum of two years, and design and construction would be expected to last six to 12 years.
The study began in 2015 and is scheduled to continue through 2018. After several public meetings in 2015 and 2016, the USACE has prepared the Draft Integrated Feasibility Report and Environmental Impact Statement (EIS), released in July 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).
