This modification presents changes to one permit site R-2915 Individual Permit Modification Application Page 2 of 9 in the E section (Site 8B) where installation of a new stormwater pipe will result in additional temporary stream and wetland impacts as well as stream bank stabilization impacts to Little Buffalo Creek and wetland W110 due to a temporary bore pit required for the stormwater pipe installation. All changes in impacts due to the new stormwater pipe and the associated temporary bore pit at Site 8B in the E Section are in red italics. Please see the enclosed DWR Pre-Filing Meeting Request Form and revised permit drawings for Section E. Summary of R-2915 Jurisdictional Impacts: Impacts for the overall (Sections A-E) project will include 3.05 acres of permanent wetland impacts, 0.28 acre of temporary wetland impacts, and 0.05 acre of hand clearing in wetlands. There will also be 9,147 linear feet of permanent stream impacts (7,485 linear feet of fill and 1,662 linear feet of bank stabilization), and 0.42 acre of temporary stream impacts (see Tables 1 and 2 for a breakdown of impacts by Section).

All other streams are Class C; Tr+ waters. 2 – Values are based on rounding † – Final mitigation requirement will be up to the USACE and DWR Permit Site 8B: At Station 746 to Station 747, there is an existing slope failure directly beside the north bound lane, on the east side of the road. This issue has been ongoing for several years, and has resulted in several similar slope failures, although the existing slope failure is relatively recent. The issue is believed to be caused by saturated soils and originating from the hillside on the west side of the road. Following a recent review of this issue, the permitted stormwater system for R-2915E at this location was found to be inadequate. The NCDOT Hydraulics Unit studied the issue and recommended a change in the permitted stormwater plans at Station 748, with the primary change including the addition of a 42” welded steel pipe. Installing this pipe should alleviate the saturated soils and help convey stormwater from the west side of the road to the eastern side and into Little Buffalo Creek. Closing the road and excavating/trenching in the new 42” stormwater pipe is not an option due to very high traffic volumes (several businesses and Ashe County High School are at this location), and there is no good detour option. In order to excavate/trench the road and install the pipe, NCDOT would need to cut into and slope the hillside on the west side of the road and expand the roadway, which will be done eventually in order to compete the R-2915E project. However, that cannot be done until NCDOT dries that hillside up, which will first require the pipe installation. As a result of these issues, the best course of action is to bore and jack the 42” pipe into place. With limited area to put the bore pit, it will be placed partially within a stream wetland complex on the east side of the road, resulting in temporary impacts to both the stream (Little Buffalo Creek), and part of the adjacent wetland (W110). Dewatering Little Buffalo Creek to accommodate the bore pit will be accomplished by installing a diversion pipe, which will remain in place until the project is complete (estimated 2-4 weeks). This activity will result in a total of 170 lf (0.01 acre) of temporary stream impacts. The temporary R-2915 Individual Permit Modification Application Page 8 of 9 dewatering pipe will be buried 42” (the diameter of the pipe), and will not be covered, but instead held in place by Class B stone, placed every 10’ on top of the pipe. Class I riprap wrapped in geotextile will be used to create a temporary headwall and endwall to stabilize the inlet and outlet of the temporary diversion pipe. This will keep the pipe in place during high flow events and prevent water from running around the pipe. All stream material excavated from where the diversion pipe connects to the stream channel and bore pit will be stockpiled and returned to the stream once the project is completed. All disturbed streambanks will be sloped to 2:1, seeded with native/riparian seed mix and covered with coir fiber. In addition, live stakes of willow and silky dogwood will be planted. Part of the stream diversion pipe and the bore pit will be installed within a wetland area (wetland W110) adjacent to Little Buffalo Creek resulting in 0.13 acre of temporary wetland impacts. After the bore pit has been removed, NCDOT plans to re-establish wetland habitat in these impacted areas. To allow for this, any wetland soils excavated for the temporary diversion pipe and the bore pit will be stockpiled and returned to the wetland upon completion of the project. All disturbed areas in the wetland will be seeded with native/riparian seed mix, covered with coir fiber, and live stakes of willow and silky dogwood will be planted. To keep the work area dry (since the bore pit will be located partly within a stream and wetland area), all water entering the bore pit will be pumped into a special stilling basin/silt bag, which will be located downstream of the project on the west bank of the stream. This will keep the silt bag out of the wetland area, and all water treated by the silt bag will be allowed to flow over existing vegetation and into the creek. Once the project is complete, the geotextile and 57 stone base, and silt bag will be discarded, and the area impacted will be seeded with native/riparian seed mix and covered with coir fiber. Once the dewatering activities have been completed, there will also be 10 lf of streambank stabilization with Class II riprap to Little Buffalo Creek at the outlet of the new 42” pipe to dissipate flow from the pipe and prevent scouring of the streambank. Previously permitted impacts at this site were <0.01 acre (20 lf) of temporary impacts to stream S135 (Little Buffalo Creek) and <0.01 acre of temporary wetland impacts in wetland W110 due to plugging and filling the nearby 24” CMP. Total impacts to this site due to this modification are now 0.01 acre (170 lf) of temporary impacts to stream S135 (Little Buffalo Creek) and 0.13 acre of temporary wetland impacts in wetland W110 due to temporary dewatering to accommodate the new bore pit. Additionally, there will now be 10 lf of stream bank stabilization at this site at the outlet of the new stormwater pipe. MITIGATION At this time, DMS is providing compensatory mitigation for all impacts. Table 5 summarizes the total mitigation needs as 3.05 acres of wetland impacts and 7,485 linear feet of stream impacts. No additional mitigation is required due to the additional temporary stream and wetland impacts and added stream bank stabilization at Site 8B in the E Section (described above) as these activities do not constitute a loss of water.
