CHA is pleased to announce it has earned two Honor Awards in the ACEC Virginia 2019 Engineering Excellence Awards for the Accomack County Landfill Closure and Glover Park.
Accomack County Landfill Closure
CHA was retained by Accomack County, Virginia to provide permitting, design, bidding, contract administration and construction observation for the closure of its landfill cells. In this geographic region, the sandy soils easily erode leading to difficulties in keeping the soil barrier layer in place during construction. CHA worked with Watershed Geo to close the landfill using a new landfill closure technology called ClosureTurf®, an innovative synthetic grass product, to cover the geomembrane without this barrier soil. The Accomack County Landfill was only the second landfill in Virginia to utilize this product.
ClosureTurf® was used in lieu of placing approximately 20,000 cubic yards of barrier soils, saving about 1,000 truck trips. This has the net benefit of reducing the carbon footprint during construction by up to 80%. The long-term benefit of using ClosureTurf® is reduced maintenance costs over the 30 years of post-care for the landfill. The manufacturer of the turf estimates that average maintenance costs will be reduced by approximately 90% per acre per year over the 30-year life of the cover.
Henrico County Glover Park
Glover Park is a world-class sports complex that was developed to serve Henrico County, Virginia residents. CHA developed a master plan consisting of 10 multipurpose athletic fields, a championship stadium, passive walking trails, public restroom buildings, and supporting infrastructure. CHA then prepared design documents for Phase I, which included four of the eight synthetic turf multipurpose fields, the sand volleyball courts, public restrooms, walking trails, supporting infrastructure, and parking. More than 488,000 square feet of synthetic turf was used in the design of two large turf pads that each accommodate two full-size soccer fields in the north-south direction and four youth fields in the east-west direction. To gain maximum flexibility for the large synthetic turf pads, our team used a sports lighting design that eliminates poles between the full-size fields. Safety complements this flexibility; the fields include a shock pad underlayment that absorbs impacts to enhance player safety, and organic material is used in the infill of the synthetic turf in lieu of traditional crumb rubber.
The ACEC VA Honor awards will be presented at the annual EEA Awards Gala at the Jefferson Hotel in Richmond, Virginia, on February 7, 2019. The Accomack County Landfill Closure will receive an Honor Award in the Environmental, Stormwater, Water Resources Category. Glover Park will receive an Honor Award in the Surveying, Mapping, Special Projects (Recreational Facilities) Category.
