The Division will likely request additional information regarding the construction details for the HDD activities but for now if we can just have an updated plan showing the location that will help". (ClearWater) Please see attached new Figure 5.1. Regarding the 25-foot buffer/protective fencing on undisturbed wetlands/streams: Thanks for getting that going as it will be a condition of our permit. Can this be extended to the five archeological sites referenced in Renee's January 14, 2020 letter? (ClearWater) Yes, protective fencing around Cultural resource areas has already been installed at sites 82 and 85. Fencing will be added at the remaining three locations before work begins near those portions of the site. 3. Regarding the Substation and revised building pad boundaries, coordination with Renee/SHPO will need to happen to make sure nothing has changed with regards to effects to listed historic properties. I'm assuming not but please provide a separate email to me covering these changes in relation to surveyed archaeological sites and historic structures so I can coordinate accordingly with their office. The location for the HDD footprint needs to be included as well if it outside previous project boundaries. (ClearWater) A separate email was sent to you on March 17, 2020 regarding the status of additional review. The completed addendum was emailed to you on March 26, 2020. 4. The Draft River Safety Plan (provided in 01/06/20 email): Please verify if there are any missing outfitters. We discussed the company next to Carrier Park and another potential company off Riverside Drive in Woodfin that needs to be included. Please see the revised River Safety Plan. (ClearWater) We have added two additional outfitters to the River Safety Plan. We are not aware of anyone else at this time but are continuing to review and will update this as necessary. 5. Additional information on minimization at bridge location (i.e. three lane versus five lane bridge): Please quantify the difference in impacts for a 3 versus 5 lane bridge, clarification on what future uses may be supported by a five lane bridge, and if DOT is requiring the pedestrian/sidewalk portion. (ClearWater) The raised center median of the currently proposed bridge (wide enough for five lane) is located such that it aligns with the existing intersection of NC 191(Brevard Rd) and the Blue Ridge Parkway Access Road and does not require relocation of this intersection. Relocation of this intersection is not considered feasible for this project as doing so would have major constraints including National Park Service land, steep topography in the northwest quadrant and Bent Creek passing just south. Relocating this intersection would require realignment of the Blue Ridge Parkway Access Road which would also likely require extension or relocation of existing culverts over Bent Creek. If a narrower three -lane bridge were constructed initially, it is anticipated the raised median would be constructed in the same location as the current proposed median (in order to line up with the existing intersection as noted above). If an additional 12-foot lane was added in each direction for future bridge widening, it is expected that 12 feet would have to be added to each bridge face as opposed to adding 24 feet to one side due to the insufficient distance (approximately 150 feet) between NC 191 and the start of the bridge for traffic to shift 12 feet over. If the bridge was built in two phases, the total footprint of temporary causeway impacts for both phases combined (this includes both the 12 month and 3 month portions of the causeways) would exceed that of the current proposed five -lane bridge. This is primarily due to the temporary causeways being required to extend both up and downstream of the bridge footprint during the future expansion, whereas the causeways are only required to extend downstream of the current proposed bridge. (e.g. Current bridge temporary impacts allow for workpads to extend 25 feet downstream of the downstream bridge face as large cranes will sit on these pads to hang the steel girders. Impacts extend an additional 9 feet downstream to account for side slope down to river bottom. For the future expansion, cranes would not be able to reach over the original bridge to hang girders on the opposite sides, so workpads would be required to extend these same distances both up and downstream of each respective bridge face.) Estimated total temporary causeway impacts for a three -lane bridge and the future widening are 0.55 and 0.58 acres, respectively. This gives a total of 1.13 acres with 0.33 acres of this being overlap between the two phases leaving a total of 0.80 acres of temporary causeway footprint when not double counting the overlap. By comparison, total temporary causeway impacts for the current five -lane bridge are 0.67 acres. If the bridge was built in two phases, total permanent stream impacts for both phases would be expected to roughly match the corresponding permanent impacts for the current proposed five -lane bridge. Estimated total permanent bank stabilization impacts for a three -lane bridge and the future widening are estimated at 88 LF (0.024 acres) and 26 LF (0.007 acres), respectively. This gives a total of 114 LF (0.031 acres) which matches the current five -lane bank stabilization impacts. A three -lane bridge would be expected to have four piers per bent with two bents giving a total of 0.004 acres. The expansion would likely add an additional pier to each end of each bent giving an additional 0.002 acres. This total nearly matches the estimated total permanent drilled pier stream impacts of 0.005 acres for the current five -lane bridge. The bridge and road will incorporate elements of multi -modal transportation and NCDOT Complete Streets design criteria to facilitate turning over maintenance of the bridge to NCDOT. If additional lanes are required in the future, the striping on the bridge could be changed to accommodate these lanes. The bridge is being proposed because as discussed above and in the PCN submittal there are financial and environmental benefits to undertaking construction of this bridge all at one time, even if additional lanes are not needed for years or decades. Update on Coordination/Status of Application: Section 106 NHP — see above request (#3) but have forwarded a draft copy of the MOA to our legal counsel for review/comment that proposes a data recovery plan to mitigate the adverse effects on the only eligible site (archeological site on west bank of River in bridge footprint). MOA will need to be finalized before can issue our permit. Section 7 ESA— Currently waiting on finalized Biological Assessment and then Biological Opinion to be issued before can issue our permit. Section 401— Unfortunately the public hearing has been canceled but it appears written comments will be accepted until April 20t". Please note that we will likely not wait on the issuance of the 401 to issue the 404/10 permit as long as I have everything I need on my end. USFS-Bent Creek Experimental Station — we had a request from the archaeologist to review the application and survey/reports which I have forwarded but haven't received any comment back on yet. Let me know if you have any questions, thanks!

Coordination and signage: o Coordinate with the recreational boating outfitters in the area to develop and provide signage alerting users to this project/construction and recommended put in/pull out areas. o Coordinate with the NCDOT on this effort since similar effort has been made for the 1-26 bridge demolition and construction in progress. o Provide signage upstream and downstream of the bridge to alert river users to construction. These signs will note that the last public pull out is at Bent Creek River Park, 400 feet upstream of the bridge. These signs will be placed at the following locations; all are public with the exception of the privately owned launches marked with an asterisk (*): ■ Headwaters Outfitters* — 25 Parkway Road, Rosman ■ Champion Park River Access (Transylvania County Parks and Recreation) —Old Turnpike Road, Rosman (1" public access from the headwaters) ■ Hannah Ford Campground - Headwaters Outfitters* - Green Road (SR1127), Rosman ■ Island Ford River Access (Transylvania County Parks and Recreation) —Island Ford Road, Brevard ■ Hap Simpson Park (Brevard Parks and Recreation) — 968 Greenville Hwy, Brevard ■ Wilson Road River Access (Transylvania County Parks and Recreation) — Wilson Road, Pisgah Forest ■ Penrose Boat Ramp (NC Wildlife Resources Commission) — 170 ApacDrive, Penrose ■ Blantyre Park (Henderson County Parks and Recreation) — 500 Cliff Road, Penrose ■ Horse Shoe River Access Park (Henderson County Parks and Recreation) — Horse Shoe ■ Westfeldt Park (Henderson County Parks and Recreation) — 83 Old Fanning Bridge Road, Fletcher ■ Glen Bridge River Park (Buncombe County Parks and Recreation) — 77 Pinners Road, Arden ■ Corcoran Paige River Park (Buncombe County Parks and Recreation) — 9Pinners Road, Arden ■ Bent Creek River Park (Buncombe County Parks and Recreation) —1592 Brevard Road, Asheville ■ Zen Tubing* - 1648 Brevard Road, Arden ■ Hominy Creek River Park (Buncombe County Parks and Recreation) —194 Hominy Creek Road, Asheville ■ Asheville Outdoor Center* - 521 Amboy Road, Asheville ■ French Broad Outfitters* - 704 Riverside Drive, Asheville ■ Mills River Park (Town of Mills River) — 124 Town Center Drive, Mills River (This park is near the confluence of Mills River and French Broad River and a common starting point for paddlers of the French Broad River.) o Signage on the causeways to warn river users away and prevent river users from using the causeway as a stopping point. • Physical restrictions o Use of a floating navigational aide to mark the safe passage lane. o Effort will be made to prevent construction material from falling on river users during bridge construction. This effort includes placing temporary plywood below bolted splices during girder erection and along the bridge deck exterior. Once girders are in place, continuous stay -in -place metal forms will be installed on top of the girders throughout the bridge deck footprint preventing construction materials from falling below. o Steady-state red lights that are solar -powered will be placed on the causeway to alert river user to its location. Generators will not be used to provide power. These lights will be atop permanent structures, such as a pole, on each causeway for the duration of the project. The contractor will be responsible for maintaining these lights at all times during construction, replacing them as necessary. • Contractor requirements: o Develop a river traffic plan to include below items: ■ Provide one or more flaggers upstream as needed to stop river use at limited times when working over the river (e.g. setting beams) ■ Training of construction staff to teach skills in aiding a distressed boater — This is meant as an extra precaution for both staff and river users. It does NOTimply that the contractor will provide "lifeguard" type services. Must have a life vest and/or boat on site.
