Project Description Heading link
This project aims to reduce the significant flooding that occurred in a subdivision named Mirage located in Joliet, Illinois. During storm events in May 2020 and April 2013, heavy damage to residential property and public infrastructure was caused by flooding. The watershed leading to the Mirage subdivision includes a large farmland area directly west of the subdivision which has a steep slope and a low soil infiltration rate that creates surface runoff flowing onto County Line Road and Desert Drive. The existing stormwater infrastructure does not have adequate capacity to convey the direct runoff from the subdivision and the adjacent farmland for short-duration, high-intensity storm events. This project provides an analysis of the existing stormwater infrastructure simulating these two storm events and identifies potential solutions to reduce flooding.
The proposed design includes new stormwater pipes, manholes, and a new detention pond that will effectively divert the excess water away from residential properties. A cost-benefit analysis has been done to determine how much money was saved by implementing the design versus the amount of damage done by these storm events. The alternative solution is buyouts, which serve as a comparison of project feasibility and cost-effectiveness. The goal is to reduce flooding and the cost of damages for storms similar to the April 2013 and May 2020 storm events.
