GHA provided preliminary and final engineering design services for the Wildwood Presbyterian Church on a 4.81-acre parcel located in unincorporated Lake County, Illinois. The property is bounded by Gages Lake Road, Old Gages Lake Road, and unimproved Dada Court right of way.
Stormwater management was a major aspect of the planning and design of the site. This was due to the upstream drainage area that flows through the site, evidence of wetlands, and three low-lying depressional areas. Based on the determined base flood elevation, compensatory storage in addition to the site’s detention requirements were provided in the development of the site. Managing these stormwater aspects while providing the church’s desired site amenities proved to be the biggest challenge.
