PROJECT SUMMARY: The applicant proposes to perform maintenance excavation of an existing canal connecting a public boat ramp to the Croatan Sound. Project Setting The proposed development site is a canal on Dare County property located at the end of Bowsertown Road (SR 1131) near the intersection with California Lane (SR 1345), on Roanoke Island. The property is approximately 100 acres in size. Approximately 70% of the property is a Coastal Wetland Marsh that is vegetated with Juncus roemerianus. The wetland area is located on the western side of the property and is adjacent to the Croatan Sound. The upland area of the property is developed as a solid waste transfer site for Dare County located on the northeast side and a NCWRC boat ramp and parking area located on the southeast side. The solid waste transfer site was once the County Landfill. Vegetation in the upland areas consists of pines and indigenous grasses and the soils in this area are a sand, sand loam type. The existing canal is approximately 2,500 feet long and 50 feet wide with a controlling water depth of -1.7 feet and an average water depth of -3.2 feet below NWL in the center, of the canal. The shoreline of the canal in wetland area consists of Juncus on the south side and a spoil ridge along the north shoreline with Juncus behind the spoil ridge. The shoreline of the canal in the upland area is a pine forest on the south side and the landfill area on the north side. The canal connects to a natural waterway that connects to the Croatan Sound. The waterway is approximately 1,800 feet long with a width that varies from 60 feet to 120 feet and has a controlling water depth of -1.5 feet and an average water depth of -3 feet below NWL in the center of the fairway. NCWRC hazard buoys are located along this waterway. The shoreline along the waterway is Juncus. The water depths in the Croatan Sound near the project area are approximately -5 feet below NWL. The bottom material in the project area consists of muck material with some sand in the areas nearer to the Croatan Sound. The adjacent properties are undeveloped salt marsh tracts. The waters of the Croatan Sound are classified as SA in this area and the area is closed to shellfish taking. No submerged aquatic vegetation was observed at the proposed work site. Development Proposal In order to improve boating access, the applicant proposes to excavate the Bowsertown Canal and waterway to a controlling water depth of -6 feet (5'+ l' OD) below NWL. The activity will be performed by an excavator on a barge and excavated material will be placed on another barge and brought to the old landfill site to be unloaded. The material will be deposited at the site on a 1.45- acre area that will be surrounded by silt fence. F The proposed maintenance excavation will remove approximately 13,800 cubic yards of bottom material and storm debris. In the canal, the proposal is for a 16-foot wide channel for the upper area and a 20-foot wide channel for the rest of the canal and waterway. Field Investigation Report: Dare County, Bowsertown Canal Page 3 Antichwed Impacts The development proposal with result in approximately 62,400 square feet of Public Trust Area (PTA), Estuarine Waters (EW) Areas of Environmental Concern (AECs) being excavated in the canal and approximately 57,000 square feet of PTA, EW AECs being excavated in the waterway connecting to the Croatan Sound. Sidewall excavation is included with each figure. The proposed unloading site will result in approximately 1,750 square feet of Estuarine Shoreline AEC being disturbed and the proposed spoil site will involve approximately- 1.45 acres of uplands. Temporary water turbidity will occur during the excavation of the canal and use of the boat ramp will be restricted. An Environmental Assessment of this project was circulated with a Finding of No Significant Impact issued on April 14, 2006.' Submitted by: Frank A.

The Bowsertown Canal is a public access waterway that is located on the western side of Roanoke Island within unincorporated Dare County near the town of Manteo. The eastern end of the canal is located near the intersection of Bowsertown Road and California Lane and the canal extends toward the west for a distance of approximately 4,200 feet where it opens into the Croatan Sound. The canal varies in width from about 40 to 50 feet at the eastern end to approximately 150 feet at the western end. The canal was constructed many years ago as a "mosquito ditch" and subsequently was used as an access channel for small watercraft. About 15 years ago, the Wildlife Resources Commission in conjunction with Dare County constructed two boat ramps and a large parking area on the southern side of the canal at its eastern end. This facility is frequently utilized by both commercial and recreational watercraft. In recent years, however, use of the canal has become somewhat limited during low tide conditions. A recent survey indicates that some areas of the canal are less than three (3) feet deep, measured from mean low water. The Dare County Oregon Inlet & Waterways Commission is proposing to perform maintenance dredging of the canal. We are proposing to mechanically excavate at least 8,500 cubic yards of material from the canal and place it at the old Dare County Landfill and Transfer Station site located just north of the canal. The following sections briefly describe the details of the project and the methods that we are proposing to accomplish the project. Boat Channel A review of the information that we have pertaining to this canal does not reveal a history of maintenance dredging. The only information we do have indicates that the original mosquito ditch was excavated during the 1950's or very early 1960's. At this time, the straight portion of the canal (approximate Station 18+00 to Station 44+00) was excavated in order to "improve" drainage, as was typically done within many coastal marshes throughout the area. During the 1970's, this straight portion of the canal was re- excavated in order to mine sand to use as a foundation for the new landfill under construction at the east end of the canal. It appears as if the material was excavated from the north side of the canal and was placed along the canal edge to construct a haul road. Once this road was completed (or as it was being constructed), additional material was removed from the canal and was hauled to the new landfill area. At the completion of all of this work, the haul road remained in place along the north side of the canal. This upland area averages about 4 feet above the water level, has a width ranging from 30 to 50 feet, and is fully vegetated with upland species. It would be my estimation that the canal was excavated fairly deep in order to obtain as much material as possible for the landfill. Based upon the fact that no formal channel alignment presently exists, a channel has been designed using the information obtained from a hydrographic survey performed in March 2005 (see project drawings). The channel has been positioned in the naturally deepest portions of the canal in order to minimize the volume of excavation. The project drawings show the channel dimensions and alignment. The channel will have a bottom width of 20 feet from Station 0+00 to 25+02 and a width of 16 feet from Station 25+02 to 43+42. The depth of the channel will be at least 5 feet below mean low water (MLW) and the sideslopes will be 3:1 (3 horizontal to 1 vertical). The channel has been designed to ensure a minimum separation of ten (10) feet between excavation of the bottom and the edge of the coastal marsh. As can be noted from the drawings, the bottom depths at the mouth of the canal in the vicinity of station 0+00 are approximately 8 feet. The quantity to be removed based upon the March 2005 conditional survey is about 8,500 cubic yards to the grade depth of 5 feet. To obtain one foot of overdepth would require the dredging of an additional 5,300 cubic yards, or a total of about 13,800 cubic yards. The total bottom area to be disturbed with this project is estimated to be approximately 168,000 square feet. During the winter of 2005, three bottom samples from the canal were obtained in order to determine the general character of the material to be excavated. The samples were obtained using a hand auger manually deployed over the side of a small skiff. In each case, a surface sample was obtained and visual observations of the material were performed. In addition, the hand auger was used to determine the consistency of the underlying materials by pushing the auger down into the bottom. Samples in the vicinity of station 33+00 and 18+00 consisted primarily of very soft, silty mud with varying organic contents. A sample in the vicinity of station 3+00 yielded a very similar material, however, a slight amount of fine sand was observed. At all three locations, the auger was easily pushed to a depth of at least 2 feet below the bottom surface indicating very soft underlying materials. Throughout the channel from Station 19+00 to 42+00, we observed some scattered woody debris consisting of tree trunks, tree branches, and root i wads that are either along the edge of the canal or are slightly lodged into the bottom. We also observed a fair amount of man-made trash and debris located along the canal banks and on the bottom. Items observed include plastic sheeting, cardboard, metal cans, scraps of fabric, abandoned crab pots, and other household garbage. Method of Excavation We plan to mechanically excavate the material from the channel limits and transport it to the old Dare County landfill located north of the canal. We anticipate that an excavator mounted on a small barge will be used to remove the material from the bottom. The material will be loaded onto small deck barges equipped with containers or perimeter bulkheads in order to prevent spillage of sediments back into the canal. Small scow barges may also be used to transport the dredged material. It is anticipated that at least two of these barges will be necessary in order to ensure an efficient work cycle. The excavator barge will be equipped with spuds that will be used to secure the barge in position during a digging set. These spuds will be raised and lowered by either using the excavator or by hydraulic powered winches. An additional excavator will be positioned on the north side of the canal in the area labeled "unloading area" on the project plans. This excavator will be used to unload the material barges and place the dredge spoil into dump trucks. The dump trucks will haul the material to the designated location at the northwestern corner of the landfill. We also plan to install silt curtains on both the "upstream" and "downstream" side of the unloader and on the Sound side of the excavator barge in order to minimize the amount of turbidity entering the Sound. These curtains will be placed across the canal and will be opened and closed each time a barge or boat transits the canal. We anticipate that it will take two to three (2-3) months to complete this project. Disposal Area The Dare County Landfill was used for many years as a sanitary landfill that served most of the northern portion of the county. In 1981, a garbage transfer station was constructed on the same site so that all sanitary waste could be transported to other landfills. In March 1982, the landfill was closed to further burial of household garbage and the transfer station began operations (please note that construction and demolition (C&D) debris continued to be disposed of at this site until 1990). At the present time, the surface of the old landfill is used as a staging area for the drop-off, !sorting, and loading of recyclable metals. The building at the eastern end of the property near the road continues to serve as a solid waste transfer station. As mentioned above, we anticipate that all of the dredged material will be placed within the designated spoil area at the northwest corner of the landfill. As the drawings indicate, a wire reinforced silt fence will be installed around the entire perimeter of the spoil area to minimize, or eliminate, any oil site impacts. The material will be truck-hauled the short distance from the barge unloading area to the spoil site where it will be dumped onto the ground. An existing haul road within the landfill will be used - no additional roadways will be constructed. The material will be unloaded into a single layer ranging from 4 to 6 feet in depth. If additional space is needed within the disposal area as it is being filled, the dewatered material may be re-excavated and placed into a higher pile. The height of the spoil material, in any case, will be minimized in order to lessen the potential for erosion. At the completion of disposal operations, the spoil pile will be seeded with appropriate plant species in accordance with the approved Erosion and Sedimentation Control Plan and Permit. It is noted that no other upland activities are proposed for this project (i.e. no areas of impervious are to be constructed as a part of this project) other than the above described temporary stockpiling of dredged material. It is worthwhile to note that a new Transfer Station is presently being constructed near Mann's Harbor on the Dare County "mainland." This new facility is scheduled to begin operations this year. Once the new facility is completed, the existing transfer station will be closed and removed and all "public works" activities on this site (garbage transfer, metal recycling, etc.) will cease. Presently, a local effort is underway to redevelop this site into a recreational area once the station is removed. We believe that the spoil material will be an asset to this redevelopment project since, if mixed with more sandy soils, it would be ideal for use as a topsoil or growing medium. In an effort to move forward with this redevelopment project, a preliminary toxicological study of the landfill and the surrounding tidal waters was performed during this past spring. This study was sponsored by Dare County, the UNC Coastal Studies Institute, and the Manteo Rotary Club. The project was funded by Dare County and through a grant from the Division of Water Resources, NCDENR. The Department of Environmental and Molecular Toxicology at North Carolina State University performed the study. Water and sediment samples were obtained from the canals on the north, south, and west sides of the landfill and were tested for a number of items, including heavy metals, PCB's, pesticides, hydrocarbons, and volatile organic chemicals. The preliminary information that is included in the draft report indicates that there are no elevated levels of contamination that would cause this project not to move forward. 06-0958 Subject: 06-0958 From: Kyle Barnes <Kyle.Barnes@ncmail.net> Date: Wed, 09 Aug 2006 16:44:45 -0400 To: Ian McMillan <ian.mcmillan@ncmail.net> 06-0958 Bowsertown Canal Dare 6/13/2006 08/09/06 CAMA/MJ Issue with condition that BMP's be installed in offloading area and storage area'to ensure project does not create water quality standard viiolations I of 1 8/9/2006 4:51 PM #drt 4 ~ ' ry ~a~ M . ~4+`! .
