This expansive project involved the reclamation and transformation of an abandoned sand and gravel quarry into a mixed-use, 650-acre development featuring multiple land uses including residential, retail, industrial, and office applications with a sizable open-space. Our team provided a wide variety of services, including a comprehensive master stormwater management plan for the entire development which required regular adjustments to accommodate individual site plans. Flood plain and flowage easement modifications along an adjoining river branch were also required. The import and placement of approximately one million cubic yards of select fill material was required to reshape and prepare the site for development. Today, Cantera is a thriving business, residential, and entertainment district enjoyed by Warrenville residents.
