Glenbard Wastewater Authority recently completed replacing the aging asphalt parking lot at its main office. To meet current needs, the lot was expanded from seven spaces to sixteen, including accessible parking. With the East Branch DuPage River directly downstream of the site, permeable pavers were utilized instead of asphalt. The use of these pavers not only reduces the amount of stormwater runoff but also improves the quality through natural filtering. Trotter and Associates assisted the Authority throughout the entire life cycle of this project.
