WBS # 1.209411 The North Carolina Department of Transportation is requesting the issuance of a Nationwide Permit 3 and 401 Water Quality Certification for the replacement of a culvert structure on SR 1180 (B Canal Road) in Washington County. The culvert is located on SR 1180 at the intersection with SR 1126 (Newland Road). The culvert structure is located in Main Canal, which is classifed by NCDWR as class "C;Sw" waters. The existing culvei�t structure consists of (2) 84" diameter X 60' long CMP's and (1) 84" diameter X 68' long CMP. These culverts will be removed using NCDOT's guidelines for culvert removal. The proposed aluminum arch culvert will be placed on the existing alignment as shown in the permit drawings. The new culvert structure is 18' X 11'4" X 59'9" with aluminum headwalls located at the outlet and inlet sections of the culvert. The new culvert invert will be placed one foot below the surveyed stream bed. Jurisdictional wetland and surface water impacts have been minimized on this project, with no permanent impacts to jurisdictional waters. This project will require the closure of SR 1180 for several days, and an off-site detour will be utilized. This temporary closure will be coordinated with the local county officials and conducted during a time period which minimizes the impact to the traveling public. Included with this letter are the location map, PCN, and permit drawings. If you have questions please call me at (252) 482-1861.

Property Identification 1a. Property identification no. (tax PIN or parcel ID): n/a 1b. Site coordinates (in decimal degrees): Latitude: 35.849193 Longitude: - 76.561507 (DD.DDDDDD) (-DD.DDDDDD) 1c. Property size: 0.10 acres 2. Surface Waters 2a. Name of nearest body of water (stream, river, etc.) to proposed project: Main Canal 2b. Water Quality Classification of nearest receiving water: C;Sw 2c. River basin: Pasquotank 3. Project Description 3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: Project area consist of NCDOT Washington County SR 1180 with Main Canal passing under the road through 2@ 84"X60' and 1@84"X68' metal culverts. The adjacent property use is a mix of agricultural and forested area. 3b. List the total estimated acreage of all existing wetlands on the property: <0.01 acres 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: 60 feet of open water in Main Canal 3d. Explain the purpose of the proposed project: Replace deteriorating metal culverts and maintain a stabile road way along SR 1180 for the safety of the traveling public. 3e. Describe the overall project in detail, including the type of equipment to be used: The existing 3 metal pipes will be entirely removed using NCDOT guidelines for pipe removal. A new aluminum arch culvert pipe measuring 18' X 11'4" X 59'9" with headwalls will be placed as shown in the provided permit drawings. The new arch pipe will be buried 1 foot below the surveyed stream bed. Once the pipe is in place and back filled a new roadway surface and grassed shoulder will be established. The headwall tie in points will likely need some rip -rap stabilization as shown on the permit drawings. Some temporary disturbance to the vegetated banks will likely occur from the dewatering process and headwall installation. These banks will be stabilized following NCDOT erosion control bmp's. There are no permanent impacts resulting from this maintenance project. This work will be accomplished using a track excavator, backhoe, and dump trucks. 4. Jurisdictional Determinations 4a.
