APM Terminals: Tidal Wetland Mitigation

Project Manager: Rick Scaffidi
Client: APM Terminals North America, Inc
Completion Date: September 1, 2006
Original Contract Amount: $1,572,972.58
Project Duration: March 9, 2006 to September 1, 2006

APM Terminals North America, Inc contracted Environmental Quality Resources to establish and maintain four functional wetlands on-site in Portsmouth, Virginia.

The prime contractor for this job was Higgerson-Buchanan. The first site, designated as site ‘A’, required 23,000 cubic yards of excavation, bringing the site down to 10” below its final grade. This space was then filled with topsoil from an adjacent stockpile site. Site B required clearing and grubbing of 0.5 acres of phragmites that had to be hauled to a separate stockpile area.

Following this, EQR excavated 3850 cubic yards of material which was hauled to another adjacent site. This wetland was then filled with 4000 cubic yards of topsoil and graded to specifications. Wetland C wraps the east side of an existing stormwater management facility.

It also called out excavation, topsoil replacement, and grading. At the completion of grading and planting an existing berm was to be removed. Higgerson-Buchanan was responsible for earthworks in Wetland D followed by excavation and grading by EQR. Following earthworks, EQR planted the site with wet-cultured plant material and a hydroseed grass mix. Site maintenance ensued for two years following the project to monitor hydrology, phragmites competition, and wildlife predation.
