Low-Impact Development

Cosley Zoo, Wheaton Park District
ERA provided survey, civil engineering, and environmental services for the zoo facility upgrades over a five-year period. The upgrades focused on green infrastructure opportunities, including a 15,000 square foot wetland-bottom detention basin, a 46,500 square foot permeable paver parking lot, and 4,500 square feet of bioswales and rain gardens. ERA also analyzed and designed upgrades to ADA parking and pedestrian features.
