The objectives of this project are:

• To determine the role of green infrastructure (GI) practices in reducing flooding by developing Long-Term Hydrologic Impact Assessment-Low Impact Development (L-THIA-LID) 2.2 models to simulate flooding (peak flow rate) and impacts of GI on reducing flooding.
• To identify the long-term performance of GI practices in reducing flooding by improving the model algorithm to simulate GI practice efficiencies considering changes in performance of practices over time.
• To enhance the optimization tool for selecting and placing GI practices to account for flooding.
• To demonstrate the impacts of GI practice adoption on flooding through use of the improved model in analysis of potential and optimal GI impacts in the Washington Park community in Chicago.
• To use the new tool to increase the understanding of impacts of GI practices in reducing flooding by providing outreach through tutorial and video instructional support including to community organizations around Chicago and classes at DePaul University and Purdue University.
