This design/build project for the United States Army Corps of Engineers (USACE), Norfolk District, at Fort Eustis in Virginia replaced 1760 feet of the railroad, including two timber bridges that spanned tidal wetlands.
Geosyntec was contracted to provide Owner‐engineering support related to erosion & sediment control as well as stormwater management for a 175‐megawatt solar energy facility in Charles City County, VA, owned and operated by a national leader in renewable energy. Geosyntec provided planning, design, and permitting efforts in support of roughly 100 acres of development that included 16 stormwater outfalls. Geosyntec’s portion consisted of two (2) “Pods” out of a total of sixteen (16) that comprise +/‐ 1,100 acres of land disturbance.
Geosyntec provided Owner-Contractor engineering support for erosion & sediment control as well as stormwater management for a 20 MWac solar energy facility in Essex County, owned and operated by a national leader in renewable energy. Geosyntec was contracted to provide professional opinion, design & permitting, as well as construction oversight on roughly 200 acres of development that included 15 stormwater outfalls.
ESI’s long-term vision is for the landfill property to transition over the remainder of its operational and post-closure life from a landfill disposal facility to a state-of-the-art renewable energy park. To extend the operational life of the Lorton Landfill, ESI plans to increase the disposal capacity by constructing a mechanically stabilized earth (MSE) berm around the perimeter of the landfill footprint. They retained Geosyntec to conduct a detailed feasibility study on the phased implementation of various renewable energy technologies (RETs) in conjunction with the planned expansion. The purpose of the feasibility study was to evaluate the technical and financial feasibility, aesthetic qualities, and regulatory and public acceptability of four RETs: solar, wind, biogas methane, and geothermal (GT) technologies. The feasibility study provides the basis for financial planning for developing the renewable energy park, particularly with regard to the optimal timing for deployment of RETs.
Dominion Energy contacted Geosyntec to design an access road and working pad to provide the utility with the ability to replace an aging transmission structure.
In order to meet the requirements of the federal coal combustion residual (CCR) rule, Dominion Virginia Power has undertaken several upgrade projects at their Chesterfield Power Station (CPS).
Southern Coal Corporation (SCC) is among the largest privately held metallurgical coal producers in the country and has a large permitted reserve. SCC is in negoatiations with the U.S. Department of Justice, U.S. Environmental Protection Agency (EPA), and five states to settle claims under the Clean Water Act.
Alpha Natural Resources (ANR) was one of America's leading producers of coal. ANR and certain of its subsidiaries (ANR) entered into a Consent Decree with the U.S. Environmental Protection Agency (EPA), U.S. Department of Justice, and three states regarding claims under the Clean Water Act.
In 2001, Crescent Resources, LLC purchased the 342-acre Potomac Yard site located in Arlington County and the City of Alexandria, Virginia, with the goal of redeveloping the property for commercial and residential uses. This site had historically been operated as a rail yard by the Richmond, Fredericksburg, and Potomac Railroad Company. In the late 1990s, a Superfund Removal Action was performed and the site subsequently was de-listed. However, human health and ecological risk assessments performed as part of the Superfund process resulted in certain residual waste materials and impacted soils left in place in the subsurface at the site. The presence of the residual/impacted materials became significant during site due diligence and redevelopment activities, with the potential to delay or otherwise undermine progress on various aspects of the redevelopment process and anticipated resale of certain parcels. Crescent selected Geosyntec to provide on-call environmental services during infrastructure construction and parcel resale with the goal of ensuring timely, "no surprises" support to these activities.
