    Thomas & Hutton provided consulting, survey, engineering, permitting, and construction observation/closeout services for the installation of 1.5 miles of the Parkway and associated infrastructure as well as the development of a Regional Pump Station, opening 4,000 acres for development. The approximately 7,700-linear foot Parkway consists of two sections and a wetland crossing. The commercial section, adjacent to SC 170, includes four lanes, a divided median, curbs, and concrete sidewalks. The rural section, westward from the wetland crossing, consists of two of the ultimate four lanes, an 8-foot multi-use pathway, and roadside swales.


    The placement of drainage infrastructure was strategically designed by Thomas & Hutton to offer innovative stormwater solutions to future developments. Water utilities to be owned by Beaufort Jasper Water and Sewer Authority (BJWSA) and include over 9,000 linear feet of 18-inch water main and connections to future development parcels. Wastewater utilities consist of +/- 1,400 linear feet of large-diameter gravity sewer conveying wastewater to a Regional Pump Station, where wastewater is pumped through a 16-inch force main. The use of deep, large-diameter gravity sewer reduces the overall number of pump stations in the PDD, limiting maintenance for BJWSA and reducing overall development costs.


    Thomas & Hutton pursued capacity credits from the utility provider, on behalf of the developer, Argent Land Holdings and oversaw the master planning process to determine wastewater conveyance and stormwater needs of various future land use needs while eliminating maintenance costs for the community.


    East Argent Pump Station & Regional Parkway received a 2021 ACEC Georgia Engineering Excellence Awards Merit Award.
