The City of Jefferson City retained Barr to assess chronic flooding and design replacement stormwater infrastructure for several neighborhoods, including Mesa Avenue, Chickadee Road, Stadium Road, Douglas Drive, and Cedar Hill Drive. In recent years, these locations experienced localized flooding that impacted roads and homes. Barr was tasked with performing hydrologic and hydraulic (H&H) analyses to determine options to reduce and better manage flood risks. Before starting the analyses, we developed a citywide impervious-layer dataset that was incorporated into the detailed H&H models. For each location, we used PCSWMM to delineate watersheds and develop H&H models for predicting stormwater flows and flood levels and corrective options. Barr prepared a feasibility assessment report describing the work performed, possible flood-damage reduction options, opinions of probable cost, and our recommendations. In 2018, Barr prepared the construction plans, specifications, and project-design reports for two of the highest-priority areas. We also provided as-needed assistance to the city during construction in 2019. The city is evaluating the options presented in the report and plans to develop a priority list for future design and construction.
