Why does the Union Pacific underpass continue to flood when there’s heavy rain? I thought that was supposed to be fixed.

Matt Bond, city stormwater engineer, said city storm sewer systems are typically designed for 10-year storm events. During the recent reconstruction at Second and Locust streets, the city included several engineering systems that are designed to improve the hydraulic efficiency of the overall system. Those improvements included reconstruction of existing curb inlets to larger sizes, the addition of a new curb inlet and the reconfiguration of the overall storm sewer piping network. The projects are meant to lessen the frequency that the underpass floods and to shorten the duration when it does.
