Carpenter Elementary School – Park Ridge, IL

Bono Consulting was recruited to assist Community Consolidated School District 64 (CCSD 64) with design and construction observation for site drainage improvements, a new teacher parking lot, new soccer fields, and playgrounds at the K-5 school. The teacher’s parking lot had poor drainage with no storm sewers, making it very dangerous with all the ice in the wintertime. The soccer fields also had inadequate drainage and were unplayable for several days after a rain event.

Park Ridge is a combined sewer area under the jurisdiction of the Metropolitan Water Reclamation District of Greater Chicago (MWRD). The challenge on this site was to design underdrains that would collect water from under the playgrounds and soccer fields, route it through an underground StormTrap® detention system, and provide an outlet in a combined sewer.

We staged many negotiations with MWRD. In the end, we decided to pump the detention storage to an underground infiltration system with a bubbler, allowing the overflow to run overland and connect to the combined sewer inlet. Incredibly enough, this project had one of the first StormTrap® underground detention systems approved by MWRD in the Chicago Metro area. The project was completed on time and is open for school.
