On-Road Structures (ORS) offer a promising alternative to traditional culvert/bridge design, with the potential to better mitigate flood impacts.  ORS use roadway embankments as dams to control flow into culverts, providing flood storage during peak flow events.  Several Iowa counties have implemented ORS in HUC12 watersheds, with anecdotal evidence indicating reduced flood impacts from recent extreme rainfall events.  This presentation will provide an overview of the project, and demonstrate the web-based information platform that was developed to guide and enhance ORS adoption in Iowa.
