One of the most visible and unique parts of the GRS project is a natural play area installed on an existing parking lot, which was retained to prevent stormwater infiltration through contaminated soil. The natural play area acts like a green roof since the soil and vegetation absorb much of the rainwater that falls. Additionally, a 4,500 cistern that harvests rainwater from 7,500 square-feet of roof surface supplies the irrigation system for the play area. Not only does this reduce runoff from the roof, it also conserves our drinking water resources.
A proprietary and highly effective Jellyfish® filtration system also treats runoff from all of the school’s parking surfaces. Jellyfish filters use membrane filtration to remove floatable debris, oil, phosphorus, nitrogen, heavy metals and suspended solids from stormwater leaving the site. These filters are installed under the parking lot.
