Foegley Plaza – Green FactsPosted on October 25th, 2019 by John Foegley
In addition to being a beautiful outdoor performance and entertainment space, Foegley Plaza is a permeable brick structure which catches precipitation and surface runoff, storing it in an underground reservoir while slowly allowing it to infiltrate into the soil below.
It is probably the greenest structure on the civic theater grounds and makes the Civic Theatre one of the only not-for-profit organizations in the Michiana area with a permeable pavement structure.
During an average year the Plaza will divert over 45,000 gallons of water from South Bend storm drains and sewers.
- 264,000 lbs recycled concrete
- 36,000 lbs gravel
- 18,000 lbs limestone chips
- 2,000 brick pavers
- 3,000 lbs granite joint chips
- Over 500 man hours of time
Benefits of Permeable Pavement
Permeable pavements help reestablish a more natural hydrologic balance and reduce runoff volume by trapping and slowly releasing precipitation into the ground instead of allowing it to flow into storm drains and out to receiving waters as effluent. This same process also reduces the peak rates of discharge by preventing large, fast pulses of precipitation through the stormwater system.
Permeable pavement can reduce the concentration of some pollutants either physically (by trapping it in the pavement or soil) or chemically (bacteria and other microbes can break down and utilize some pollutants)
By slowing down the runoff process, permeable pavements can cool down the temperature of urban runoff, reducing the stress and impact on the stream or lake environment.
