Dominion Energy proposed to construct two new overhead 230 kV transmission lines (Line 2259 and Line 2262) between the proposed Unity 500/230 kV switching station in Lunenburg County and the proposed Tunstall substation in Mecklenburg County, Virginia. The project was split into two phases with a total project area of 250.12 acres and a total line length of 10.91 miles. The project site traverses rural, largely undeveloped land, and some rural residential development. Soils within the project area are generally characterized as having a moderate to severe erosion potential and a moderate to severe rutting hazard. This project focused on stormwater compliance, erosion and sediment control design, and floodplain management.
Project Role
BCE conducted hydrologic and hydraulic data review and analysis to evaluate pre-development and post-development water quantity and water quality conditions. Based on this analysis, BCE developed a Stormwater Management Plan and an accompanying Stormwater Calculations Report. Additionally, BCE prepared a waiver letter request for areas within the Limits of Disturbance where no land use conversion was proposed. Drainage areas were analyzed to establish sizing criteria for erosion and sediment controls required during construction. BCE also reviewed the Erosion and Sediment Control Plan to ensure proper protocols were in place. As part of the project, BCE prepared a floodplain study to evaluate the floodplain conditions within the vicinity of the proposed transmission lines.
