Study Process

The Feasibility Study began in May 2014 and was completed in 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 evaluated and compared alternative plans based on several factors, including the benefits and costs of each waterway. Following that analysis, 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.

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. (See USACE news, July 2019)

After the Study

Once authorized by Congress, 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. If the project is funded in the future, appropriations would occur over many years, as well as construction. 


Denver Waterways Timeline

The study was completed in 2018. Securing funding for implementation would take a minimum of two years, and design and construction would be expected to last six to 15 years.
