Research to Support Design and Siting of Deposition Areas for Dredged Material from the Rodanthe Emergency Channel

The Rodanthe Emergency Ferry Channel (REFC) is essential for transporting emergency personnel, equipment, and supplies to Hatteras Island communities following any event that renders the Herbert C. Bonner Bridge and/or North Carolina Highway 12 impassable. The N. C. Ferry Division runs ferries during these emergency situations from Stumpy Point to Rodanthe. Maintaining this channel is a public safety issue and addressing any associated logistical challenges is a NC DOT priority. The REFC is currently too shallow to allow safe passage of the ferries. There is only one landward dredge material deposition site available, but it is not large enough to accommodate the amount of material generated by dredging the channel to necessary depths/ widths. There are limited locations available on land due to dense residential and business development in the area, as well as U. S. Fish and Wildlife property. This project was developed to provide the needed site characterization to assist the NC DoT Ferry Division with assessing the use of dredge material and minimizing negative impacts of dredge material deposition. The data presented provides an improved understanding of the geological, ecological, and anthropological factors affecting siting of dredge material deposition sites. The decision framework developed is based on best available data from the study area and information from similar sites in the literature.
