Box 27687 Raleigh, North Carolina 27611 ATTENTION: Mr. John Parker Dear Sir: R. SAMUEL HUNT III SECRETARY I !?r AUG 11 1993 --------------------- SUBJECT: Dare County, Beach Nourishment North of Buxton, State Project No. 4.5050009. A narrow stretch of NC 12 just north of the Buxton town limits (see sheet 1 of 4) has been the site of many past problems relating to coastal erosion and overwash. In 1962 an inlet opened as a result of the Ash Wednesday storm and was closed later that year by the Army Corps of Engineers with sand from Pamlico Sound. A major beach replenishment effort took place in 1983. Today, recurring flooding leads to periodic closing of NC 12, occasionally undermines the road, and severs power and water service to the area. In an effort to offer long term protection for NC 12, the North Carolina Department of Transportation initiated in 1988 an investigation by The Center for Transportation Engineering Studies at North Carolina State University entitled "Options for North Carolina Coastal Highways Vulnerable to Long Term Erosion." This study identified threatened stretches of coastal highways throughout the state, and offered site specific solutions to lessen the impacts of erosion and storm damage. The study identified the section of NC 12 in question as a threatened roadway. The study suggested either roadway relocation or roadway relocation with an elevated causeway as ways to provide long term protection to NC 12. The Department is currently studying these options for long term highway protection north of Buxton. However, in an nw* effort to protect NC 12 for the immediate future, NCDOT is proposing to pump 200,000 cubic yards of sand from an area in the Pamlico Sound known as the Canadian Hole to a 5000 foot stretch of oceanfront beach beginning approximately 2,000 feet north of the Buxton town limits. The proposed borrow area shown on sheet 4 of 4 is approximately 170 acres in size. Almost half the area has been previously dredged. NCDOT only proposes to excavate approximately 6.2 acres of the site to a depth of 20 feet.. Material will only be taken from undredged areas. While photographs indicate that much of the proposed borrow area supports submerged aquatic vegetation (SAV), it does appear that sufficient unvegetated bottom exists to allow for 6.2 acres of excavation. Final selection of borrow sites will be made after coordination with the National Marine Fisheries Service. The dredging will be carried out by a NCDOT Ferry Division maintenance dredge. The material will be pumped through pipes underneath the roadway and onto the beach. It is not anticipated that an access canal will be required for this dredge. NCDOT geotechnical engineers have examined the proposed borrow material. Their findings given in the enclosed geotechnical survey report. The pumped sand will be spread on the beach by mechanical means. This operation will continue until an approximately 50 foot wide berm is created (see Typical Section, sheet 3 of 4). The frontal slope will not be controlled, and will be allowed to reach natural equilibrium. After placement of the 50 feet of sand berm, natural processes will be allowed to reform the beach features, as indicated by the estimated typical adjusted profile line shown on sheet 3 of 4. The berm will be tapered back starting at a distance of 1000 feet to either side of the project limits (see sheet 3 of 4). The Department feels that the proposed plan outlined herein will provide the minimum necessary to protect this vulnerable stretch of roadway. Application is hereby made for authorization to allow the above referenced work to proceed. Included for your information are a set of permit drawings, permit application and geotechnical survey report. A $250 processing fee will be forwarded to your office within the next week. We are in the process of obtaining a Special Use Permit from the National Park Service. This permit will be forwarded to the appropriate environmental review agencies upon receipt. By copy of this application we are requesting the appropriate permit authorization from the U.S. Army Corps of Engineers. The N.C. Division of Coastal Management, upon accepting this application package as complete, will solicit comments from the N.C. Division of Environmental Management. NCDOT is anxious to initiate nourishment activities by early October. Therefore, we would appreciate expeditious processing of our permit request. We would also like to request copies of all comments received during the permit review process. If you have any additional questions regarding this matter, please contact Mr. Doug Huggett of NCDOT's Environmental Unit at (919) 733-9770. Sincerely, B J O'Q nn, P.E.

The COE requested plan drawings of each NWP site on 8 1/2 x 11 in addition to the construction drawings. The COE agreed that if a site is NWP and requires PDN (predischarge notification) then DOT will have to submit a full set of plans with the permit application. If the NWP or Individual Permit does not require PDN, then DOT will only have to submit a summary sheet and general location map with permit application. The COE has the option to request additional information and/or plans on any particular site if needed. The COE stated the drainage impact of ditches might have to be included in wetland impacts. DOT is looking for wetland mitigation sites. The COE suggested looking at a site near Raccoon Creek. DOT was reminded to distribute all environmental documents to Permit Review Agencies if a permit is required for both State and Federally funded projects. NC 12 - Dare County NC 12, Beach Nourishment North of Buxton, Dare County: Doug Huggett, Environmental Specialist, NCDOT Mr. Huggett reported DOT had submitted the permit applications for CAMA, 404, and 401 on August 10, 1993. The Right of Way Branch is securing the Special.Use Permit from the National Park Service. Mr. Huggett is to follow-up and make sure this is being pursued. Mr. Huggett presented an aerial map indicating an area north of Buxton where DOT proposes to pump 200,000 cubic yards of sand material and also indicated the area DOT proposes to borrow the sand material. Mr. Huggett stated DOT proposes to excavate approximately 6 acres of unvegetated bottom which will produce the borrow material needed. This should result in a 50 foot increase to the beach area. DOT does not consider this as a long-term solution but it does offer short term protection to the roadway. Mr. Preston Pate (CAMA) requested more definition of the area to be excavated. Mr. Pate questioned whether the SEPA process should be followed to allow the agencies the opportunity to review and comment. Mr. Pate also questioned what effect this dredging would have on the sound. DOT feels the SEPA document is not necessary; this project meets qualifications for Minimum Criteria. 5 Mr. John Parker expressed concerns regarding taking material from the sound and questioned the justification for using this site. Mr. Huggett will meet with Ron Sechler (NMFS) to determine SAV habitat areas and to identify the best area to obtain the fill. DOT will supply DCM and NMFS with color aerial photos for the project area as soon as they are available. NC 12 - Relocation of 2-mile section in Dare County Near "Sandbags": Ms. Julie Hunkins, Project Engineer, NCDOT Ms. Hunkins stated a notification for the start of this study had been distributed the week of August 9th. A interagency scoping meeting is scheduled at the Carolina Aquarium in Manteo for Thursday, September 9, 1993 at 1:30 p.m. and the review agencies have been invited to attend. Approximately two weeks later, a scoping meeting will be scheduled at DOT in Raleigh. The SEA/FONSI should be completed in January 1994 with construction to begin in late Spring 1994. This project is on US Fish & Wildlife Service property. Ms. Mike Gantt stated the USFWS is not opposed to the project at this time; but, "nationally significant resources are at stake." Discussion of Channel Relocation for Hatteras Ferry Dock and Ocracoke Ferry Dock. DOT submitted a permit modifications for relocating the channel between Hatteras Ferry Dock and the Ocracoke Ferry Dock to allow for safer passage for the ferries through the inlet. DOT has collected sediment samples at the request of the Division of Environmental Management. The area has been mapped and it appears the project area does not involve SAV's. Mr. Preston Pate urged the Review Agencies to submit their comments or request for information as soon as possible because of the urgency of the situation. NC 12, Long Range Feasibility Study: Edd Hauser Mr. Hauser stated the goal of the Feasibility Study is to update the results of the 1988-89 study conducted by NCSU on problems involved with the North Carolina coast. In 1992, Dare County asked the COE to begin a reconnaissance study of North Carolina beaches north of Oregon Inlet in Dare County. The Department of Transportation asked the COE to extend the reconnaissance study to include the beach south of Oregon Inlet. The Feasibility Study will include the above 0
