Geographic Coverage:Poplar Creek Watershed
Abstract:The Federal Emergency Management Agency (FEMA) tasked the Illinois State Water Survey (ISWS) with providing technical assistance and mitigation support to the Poplar Creek watershed communities, which include portions of Elgin, Hoffman Estates, Schaumburg, South Barrington, Streamwood, and the unincorporated areas of Cook County in Illinois. The Poplar Creek watershed lies within the Upper Fox River Hydrologic Unit Code 07120006. The objectives of this project are to help raise flood risk awareness, provide tools to communicate flood risk, and support local efforts to reduce this risk. This project provides essential, detailed data for each structure in the 0.2% annual chance floodplain in the watershed. The 0.2% floodplain is the largest magnitude frequency of flood hazard that is estimated for FEMA flood hazard mapping and encompasses the extents of lesser magnitude, higher frequency events. The risk data for each structure contain the following: average annualized loss, flood depths for multiple return periods, first floor elevation, low entry elevation, and chance of flooding over a 30-year period. These data will assist communities and the State of Illinois in preparing a cost-benefit analysis contributing to the development of a comprehensive plan of prioritized mitigation projects.
