I understand it's part of the golf course but is it a culvert extension or something else? Is it for play area or a golf path? If it's a culvert can the culvert meet burial requirements and will there be any temporary dewatering impacts, or adjacent stabilization impacts associated with it?

Send all suspicious email as an attachment to report.spam@nc.gov David and Sue, Good morning, High Hampton has made several changes that reduce the overall stream and wetland impacts on the project. Attached is the revised impact map set Figure 5.0 and 8 1/2x11 figures 5.01-5.10. The attached word document provides detailed Tables 1 and 2 that indicate the reduction in stream and wetland impacts from golf and road changes. This document also summarizes mitigation requirements. Should you have any questions or comments concerning this project please do not hesitate to contact me at 828-698-9800.
