PROJECT AND PURPOSE: The project consists of the discharge of fill material into waters of the United States associated with the construction of a data center facility at the subject location. The project is called Stonewall Business Park. Approximately 0.77-acre palustrine forested wetlands (PFO), 0.27-acre palustrine emergent wetlands (PEM), and 860 linear feet (0.13-acre) of stream beds will be permanently impacted by the proposed project. Compensatory mitigation will be provided by the purchase of wetland and stream credits.
