Abstract: The City of Cedar Rapids, Iowa, partnered with engineering firms and the US Army Engineer District, Rock Island, to develop a Flood Control System. In 2011, the US Army Engineer Research and Development Center, Coastal and Hydraulics Laboratory, was tasked with completing a risk assessment of removable floodwalls on the eastern side of the Cedar River. In 2016, ERDC-CHL was asked to include the temporary flood closure barriers on both sides of the Cedar River. Phase 1 of the study consisted of seven alternatives to be considered for the final FCS design, with a goal of a 90% confidence of successful deployment. Phase 2, initiated by MVR, targeted a 95% confidence level. The method used for evaluation was RiskyProject® software. The software used a Monte Carlo method of analysis to determine a range of durations, manpower, and labor costs based on logical sequencing. The results showed that the “Master Plan Minus 400 ft” alternative to be the most efficient for Phase 1. The most efficient alternative for Phase 2 was Task 5.4, which achieved a 95% confidence level of completion within 48 hours. The Phase 1 and the Phase 2 descriptions are detailed within this report.
