D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Stabilization of the dam is to occur on the side of Sutton Lake instead of the wetland/Cape Fear River side. Dam repair will not create any wetland
impacts (temporary or permanent). Dam repair activities at Breach 1 will not result in impacts to wetlands or open waters.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
Planned construction methods for repairs are set to be completed from on top of the existing dam instead of having equipment travel through wetlands
or open water. Work will be conducted in the existing footprint of the dam to prevent the need for logging or construction mats for equipment to drive
on.
