Parkway Shops is a retail commercial development located in north Jacksonville along Airport Center Drive and I-95. It consists of approximately 375,000 square-feet of commercial retail use within a 48-acre parcel. The development of this parcel required mitigation of the one-hundred-year floodplain by modification of the City of Jacksonville’s master SWMM model to obtain approval for the fill activity. This resulted in two master stormwater ponds that serve both the site and Max Leggett Parkway, which is bordering the site to the east.
A master water and sewer utility system, including a central lift station, was also necessary to serve Parkway Shops, the future retail development to the north, and a future hospital. Civil 3-D was utilized to perform mass grading analysis in order to reduce the earthwork import, generate the floodplain cross sections, and create the pipe networks for storm, sanitary, water, and dry utilities. The 3-D models allowed the designers to perform conflict checks between the multiple utilities proposed for installation and generate quantity take-offs for comparison with the project budget. Key duties of RS&H included floodplain mitigation permitting, meeting with stakeholders to arrive at an agreement on utility capacities and cost sharing, coordination with utility providers, design, permitting, and construction administration.
