Key Challenges
The full site required 80,000+ CY of fill to achieve desired grades. CCC worked with the owner to find outside fill sources that met the required environmental criteria for the residential community. The existing site had abandoned underground utility and building infrastructure to be be removed alongside several existing utilities that needed to remain in place and active
Due to the site’s proximity to the Delaware City Canal and the Delaware River, the water table provided challenges for deep utility installation and the required dewatering. In some cases utilities were installed below sea level. As the phasing progressed, the site work operations continued alongside the home building operations requiring coordination between multiple contractors and extra care while working around new occupied home as well as an active boat ramp and recreation area.
