The Niles case study will present the Niles Stormwater Master Planning and Capital Improvements. The Village of Niles is a suburb located on the Northwest side of the Chicago that was developed during the baby boom (1950’s-60’s). Historically development did not allow for overland flood routes and did not conceive of the amount of impervious cover that would be built. As a result, Niles suffers from urban flooding. Urban flooding is frequent flooding associated with undersized sewers and poor drainage located outside the FEMA flood plain. After massive flooding in 2008, the Village formed a stormwater commission to address flooding in town. This program included recommendations in four areas: capital improvements, regulatory program, maintenance and monitoring and flood control assistance. In 2017 after the successful completion of Tier I improvements, the Village initiated a stormwater master plan update that was completed in 2018. The update was needed to include the results of past projects, add analyses of potential projects, and revisit the project prioritization for the future. The presentation will provide an overview of the process used to prepare the 2018 Master Plan update. An overview of the successful aspects and lessons learned from programs and projects implemented during the first five years of program implementation will be shared. The presentation will also discuss how funding was secured for the projects using grants, sales tax, and low interest loans. Finally Village staff will also discuss how green infrastructure has been incorporated in various locations throughout the town. Director Braun will relate how the stormwater plan incorporated operation and maintenance considerations. A brief discussion will be included on how maintenance management software was used to calibrate and verify the results of the modeling. Finally the results of a trend analysis related to stormwater complaints in the database will be presented
