Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this application: There is an existing two lane paved road with existing crossline of 36 inch diameter pipe at 60 feet long on a 55 degree skew to the road. The road shoulders are vegetated. The general land use in the vicinity of the project is wooded and agricultural with a few scattered residences. 3b. List the total estimated acreage of all existing wetlands on the property: 0 acres within the review area 3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property: -150 feet of perennial stream (UT to TenMile Swamp) within the review area. 3d. Explain the purpose of the proposed project: The purpose of the project is to preserve the safety and mobility of the traveling public by replacing the existing deteriorated pipe structure and severely eroded ditches and road shoulder areas. Page 4 of 13 PCN Form - Version 1.3 December 10, 2008 Version 3e. Describe the overall project in detail, including the type of equipment to be used: The existing pipe structure is one barrel of 36 inch diameter pipe at 60 feet long on a 55 degree skew to the roadway. The proposed structure is one barrel of 66 inch wide by 51 inch high aluminum box culvert with inlet headwall and outlet headwall with wingwalls on the outlet headwall with an overall structure length of 50.5 feet (50 feet of pipe plus 3 additional inches for the inlet headwall and 3 additional inches for outlet headwall). The proposed culvert would be on a 55 degree skew to the roadway. The existing situation is that the inlet side streambed is approximately 3.5 feet higher than the outlet side streambed. This makes for a challenging proposal in trying to balance proposed pipe slope with burial requirements. There is also a substantial scour hole on the outlet end of the existing pipe. NCDOT proposes inlet invert elevation of 91.4 which matches an existing streambed reading at one foot upstream of the existing inlet. The streambed at approximately 30 feet upstream of the existing inlet is 93.0. Just downstream of the 93.0 reading, the stream passes over an apparent grade control structure (not sure what, but there is an existing small water fall which appears to be in a stable situation) and just below the grade control the streambed is 92.0. Considering the apparent stable stream bed situations as described upstream and in order to avoid destabilizing the streambed by creating potential for headcutting, NCDOT proposes to match the proposed inlet invert to the streambed elevation of 91.4 at the immediate area of the existing inlet. From here, the idea was to make a straightline slope of the pipe and filling in of the existing outlet scour hole with Class B rip rap to the point at which the downstream steambed elevation is apparently just outside of the influence of the scour hole. That downstream streambed elevation at which the streambed is apparently just beyond the influence of the scour hole is 88.1 and is located approximately 30 feet downstream of the existing outlet (or 31 feet downstream of the proposed outlet if you prefer). So taking the 91.4 elevation of proposed inlet invert and projecting across the approximate 81.5 feet (approximate 50.5 feet of proposed structure length plus 31 feet downstream to far edge of scour hole) run from proposed inlet to far edge of scour hole, we have that the pipe bottom and proposed rip rap top surface elevation would be at an approximate slope of 4.0% (91.4 minus 88.1 and then divide by 81.5). This results in a proposed outlet invert of 89.4. From the proposed outlet, Class B rip rap would be placed flush with the outlet invert immediately at the outlet of the pipe structure and then rip rap fill of the scour hole would continue downward on the approximate 4.0 % slope until tie in with the far downstream end of the scour hole. So with this proposal, the pipe would not be buried relative to the outlet stream bed and so NCDOT is hereby requesting waiver from the burial requirements in accordance with this package proposal. Also, on the inlet and outlet ends of the proposed structure, Class B rip rap is proposed for bank stabilization purposes. Also, on the NW and SW quadrants of the project there is significant erosion of the roadside ditches and on the SE quadrant there is moderate erosion of the roadside ditch. So NCDOT is proposing to shape up these ditches and install Class B rip rap in the ditches to prevent future/further erosion of the ditches. No doubt this existing ditch erosion has contributed to pollutant loading of the stream over time. The proposed should significantly reduce potential for further sediment pollutant loading. Similarly, the already discussed rip rap fill of the scour hole should help stabilize the downstream stream bed. Similarly, the bank stabilization around the four corners of the structure should help stabilize those often times hard to stabilize areas around a newly installed structure. In order to accomplish the aforesaid, we would install dams of some type such as sheet pile, metal plate, aquabarrier on inlet and outlet ends of our pipe within the proposed stream impact limits in order to work in the dry. Bypass pumping would be utilized. We would dewater our work area by use of a silt bag placed in upland areas along with other erosion control measures to further filter the water that drains from the silt bag. Pumps would be placed in upland areas. There are no wetlands within the scoping area for this project so concern over placement of pumps and silt bag in regard to wetland impacts should not be an issue here. We would remove the existing pipe. We would install the proposed structure. We would backfill the roadbed area. We would install the Class B stone for scour hole fill in, ditch stabilization, and bank stabilization as previously discussed. We would not place filter cloth under the rip rap as we believe we can achieve better stability by pressing the rip rap into the underlying soil which we would do; therefore, we hereby request a waiver from the use of filter cloth beneath the rip rap in this regard to the bank stabilization portion if such waiver is necessary. We would remove the sheet pile, metal plate, aquabarrier, or the like that was used for damming the stream; we would restore the temporarily disturbed areas as much as possible to preconstruction conditions. We would finish dressing up the roadway areas and stabilize any remaining disturbed areas with vegetation. Standard road construction and pipe replacement equipment such as cranes, excavators, dump trucks, and the like would be utilized for this project. Proper erosion and sedimentation control measures would be employed throughout the project. Finally, the roadway area disturbance would be repaved.

Impact Justification and Mitigation 1. Avoidance and Minimization 1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project. The work area has been minimized to that necessary to practically perform the work. The proposed design should help create a more stable outlet end stream channel by filling in and stabilizing the existing outlet scour hole. The proposed should also aid in aquatic passage as the current situation is an outlet end of pipe which is severely perched. Also, as previously discussed, the inlet invert proposed should help ensure that headcutting of the upstream stable channel area does not ensue post construction. The extensive addition of rip rap is proposed and necessary to correct existing and prevent future erosion of ditches and banks at this location as moderate and severe erosion currently exists in the ditches and along the road fill; these efforts should help reduce further sediment pollutant loading to the stream. Also, the proposed headwalls are instrumental in reducing the proposed structure length and come at significant costs to NCDOT as opposed to maintaining or increasing existing pipe length. 1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques. Pressing in of the stone into the soil for the proposed bank stabilization should help ensure solid connection between the stone and the underlying soil resulting in a stable situation short and long term thereby minimizing potential for delayed impacts that might otherwise occur. Proper erosion and sedimentation control practices would be used to include silt bag for dewatering into. Bypass pumping would be utilized in order to maintain downstream flows thereby maintaining flow to the downstream environment and avoid impacts that would otherwise occur if bypass pumping were not proposed. 2.
