• EB project impacts includes work inside the EC limits due to project overlap
• The permit mod for EB will cover the extension of pipe culverts and additional road work
located within the Overlap with the EC section.

• PNG Line
• NS Railroad Right of Way
• Grassy Creek — FEMA Regulated Stream
• Project located within the Yadkin River Basin. There are no specific stormwater

there are opportunities
• Identified two locations for stormwater basin
• Culverts
• 10 Large Culverts on the Project
■ Including 3 extensions
■ 2 replacements
■ 5 new crossings
■ 2 FEMA (Grassy Creek)
• New double box culvert at Grassy Creek buried 1' below streambed w/ I' flood bench
• Sills not placed in existing culverts to maintain design capacity
• Remaining culverts were not buried because of length and slope of barrel
• Riprap pads will be flush with the streambed
• 2 Small Pipe Culvert Extensions
■ Additional impacts to the R-2247EC Project

Project Design
• Project design speed increased to 70 mph
• Avoidance and Minimization
Lowered interchange to minimize Duke Power and NS Railroad conflicts
■ Reduced earthwork (million cubic yards of borrow to balanced on -site)
■ Eliminated a new continuous 1200' culvert (Ramps & Loop B)
• Retained 350' open channel inside Loop B
• Retained 100' minimum open channel between culverts
Shifted Ramp DB and Loop D away from Grassy Creek
■ Eliminated Ramp DB crossing over Grassy Creek
Reduced 1600' mainline culvert to 1200'
• Added retaining walls along west side of US 52 to minimize PNG conflicts
■ Reduced stream impacts
Discussion on method to distinguish new EB impacts from Drevious EC impacts
• See examples of Permit Drawing Sheet 19 attached at end
• Show overlapping impacts as depicted in the attachment.
■ If there is a change in impact type it should be shown with the new type of
impact hatching overlapping with the impact previously shown on the
2247EC permit drawings.
■ On the impact summary sheet impact changes should be counted on
separate lines and noted so that totals for mitigation can be properly
accounted for.
• General Comments
SHT 4
• Breakout items on impact summary table to show specific type of impact such as
inlet protection, outlet protection, channel relocation, culvert construction, etc.
• Adjust labeling for impacts from R2247 EC being shown on all plan sheets.
■ Make sure all labels are properly grey scaled, and are discernable from
each other when printed.
■ Place label beside impacts shown from R2247 EC ex. TS (EC).
• Bank stabilization should be shown with a "S" callout and noted separately in the
impact summary sheet.
• If there is no significant realignment of the channel, at inlets and outlets of
culverts impacts should be shown as bank stabilization.
