Water Street is a vibrant shopping and entertainment district located in downtown Naperville, IL. Following the curves of the DuPage River, this mixed-use redevelopment required significant innovation and engineering to come to life. Our team provided a variety of services to develop a three-story office building, a five-story mixed-use building, a five-story hotel, and a four-story, 800-space parking structure. In addition, the project’s north end adjacent to the river required the integration of detention, water quality, and floodplain management as part of the public plaza and riverwalk improvements. We proposed and designed a solution to provide permeable pavers over a combined stormwater and floodplain compensatory storage chamber within the plaza area, allowing for the picturesque experience guests enjoy today.
