IN-36: Stormwater Modeling

In 2018, Sustainability measures were taken during the construction of Lot G1. A stormwater management system was put into place, LED lights with dimmers and motion detectors are being used, trees were planted to mitigate sunlight and create shaded space and a large wetland area was constructed at the North end of the parking lot.

Stormwater Management System: In Lot G1 a bio-retention area and stormwater storage system were installed to mitigate an increase in stormwater runoff entering the municipal storm system and potential contaminants in the stormwater. Water from the parking lot sheet flows or enters a drainage system. This water then empties out to a stormwater forebay on the East side of the parking lot where suspended material drops out of the water. Stormwater then flows over a spillway into a bio-retention treatment area where it percolates through a very sandy soil. This bio-retention area is also planted with vegetation that thrives on contaminates and helps keep the soil clean after the water has filtered through. Below the sandy soil is a very large stormwater chamber system that allows a large amount of water to back-up and percolate into the ground. This stormwater management system ensures that all stormwater leaving Lot G1 is flowing at a lesser volume than before construction and that the stormwater is clean.
