Public Parks

Picture
Hoffman Park, Butterfield Park District
​ERA provided survey, civil engineering, and environmental services for the 10-acre regional park facility. The improvements included a new playground, ballfields, basketball and tennis courts, exercise stations, pavilion, bioswale, trails, and parking lot. ERA designed the improvements to function with the onsite floodplain, floodway, and wetlands, and successfully permitted the project through Illinois DNR, DuPage County, and the US Army Corps of Engineers.
