Landscape Performance Benefits

Environmental

  • Decreases daytime summer surface temperatures by an average of 23°F and air temperature by 9°F by replacing 1,500 sf of asphalt play surface with a rain garden.

  • Holds 720 gallons of stormwater (79% of the 1-year storm) in the rain garden. The ten trees in the rain garden are estimated to intercept an additional 1,600 gallons of stormwater annually.

  • Reduces annual hydrocarbon emissions by 1.83 lb and and carbon monoxide emissions by 69.2 lb, by replacing nearly 6,200 sf of lawn with an outdoor classroom that requires no mowing.
