Lisle Community Unit School District 202
Working with Perkins+Will to execute Lisle Community Unit School District (CUSD)’s new Vision 202, Eriksson Engineering Associates, Ltd. (EEA) provided civil and traffic engineering services for the new Lisle Elementary School as well as civil engineering services for the pavement maintenance improvements at Lisle High School.
Lisle Elementary School
The growing needs of the community led to the construction of a new 2-story, 100,000 SF elementary school located within unincorporated DuPage County for the District. Unlike the original elementary school, the new Lisle Elementary School design carefully considers water control as part of the site building plan. Since regulatory floodplain and wetland areas needed to be accounted for in the design, EEA developed a complicated stormwater management system (incorporating permeable pavers, a wetland bottom detention basin, an underground stormwater detention vault, and a hydrodynamic separator) that best took advantage of the site’s existing topography to provide an economical solution that met the regulatory requirements of DuPage County.
In addition to civil engineering, EEA also provided traffic and parking services for the project, working in conjunction with Perkins+Will to develop a comprehensive site plan that met the programmatic demands of the District while maintaining safety on the campus for each of school buses, passenger cars, and pedestrians.
Lisle High School 2019 Pavement Maintenance
This project consisted of pavement maintenance improvements at Lisle High School for areas such as the parking lots. The north parking lot was reconstructed to match the existing parking lot, and new concrete curbs were installed along the perimeter of both the north and east parking lots.
Due to the property being located within two distinct regulatory floodplain areas and in the proximity of an existing wetland, the parking lot improvements required a detailed compensatory storage design and necessitated permitting through both the Village of Lisle and DuPage County. EEA worked directly with the Village, County, and wetland consultant (Gary R. Weber & Associates) to ensure all regulatory requirements were met.
