BOX 25201, RALI?1CK W.C. 27611-5201 Dave Timpy, USACE John Hennessy, NCDWQ David Car, NCWRC Tom McCartney, USFWS Jim Hauser :??A Natural Systems Unit DAVID MCCOY SECRETARY Potential stream relocation for proposed Ellerbe bypass, R-2231 BR, Richmond County. Attached are the conceptual design plans for: a.potential: stream relocation which could be implemented at station 92+20 to 93+90.4R-2231: B Please note that the potential relocation would occur in an existing: wetland which.is, located on the west side of the proposed alignment. The relocated channel would.be, approximately 150 meters in length and could offset some of the expected impact at .this stream crossing. A new channel would be excavated within the existing wetland. This wetland presently occurs as a floodplain system along both sides of the existing stream. The plans, as presented, are :only conceptual in nature and would be. €malized once detailed study of the relocated stream is completed. NCDOT would like to request a determination. from the resource agencies as to whether this stream relocation is warranted and whether•it-could:be used as a mitigation measure to offset projected stream impacts for R-2231 B. cc: Charles Bruton Hal Bain Jay Twisdale PHONE (919) 733-2520 FAX(919)733-9150 I MAY-11-2000 10:06 NCDOT 919 250 4108 P.01i07 NORTH CAROLINA DEPARTMENT OF TRANSPORTATION HYDRAULICS UNIT `?wrtrN FACSIMILIE TRANSMITT CO R SHEET * * DAYE: Please deliver the following pages to: Name: Of.

BOX 25201,-RALEIGH, N.C. 2761 1-5201 GOVERNOR 2/16/00 Memorandum To: Jim Hauser Natural Systems Unit From: Abdul Rahmani Hydraulics Project Engineer DAVID MCCOY SECRETARY Subject: Responses to Avoidance/Minimization Issues on US 220 in Richmond County; TIP R-2231 B, CA, and CB Section B (Design Plans) Sheet 4 and 5 Station 93+40 Relocate stream along east fill slope where possible Response: Per email from David Timpy to Jim Hauser, offsite mitigation is preferred by Mr. Timpy Sheet 8 Station 108+60 A larger perennial channel occurs at 109+00 pipe as drawn appears misplaced. Response: Per discussion with Hydraulic consultant, the pipe is located correctly. Sheet 15 and 16 Station 136+00 Include entire surface area of the drained pond as a surface water impact, not just that within the fill slopes. Response: A revised permit drawing and summary sheet reflecting the entire pond as an impact were provided in August of 1999. Sheet 17 Station 141+00 Include entire surface area of drained pond as a surface water impact, not just that within fill slopes. Consider opportunties for on-site wetland and stream mitigation in drained pond. Response: A revised permit drawing and summary sheet reflecting the entire pond as an impact were provided in August of 1999. Per discussion with Jim Hauser concerning opportunties for on site mitigation in the drained pond, he stated that due to the small size of the remaining drained pond, mitigation would be pursued elsewhere. Section CA (Design Plans) ?l Sheet 8 Station 190+80 Consider bridging to avoid impacts. Response: A bridge/culvert cost comparison produced the following cost difference: Dual Bridges $3,633,000 vs. a double barrel culvert $441,000. (A difference of $3,192,000) Dual Bridges would save 0.66 ha (1.6 ac.) of wetlands Sheet 19 Station 234+50 Construct energy dissipator / flow spreader at culvert outfall to prevent blowing out stream and wetland with stormwater. Response: Per investigation by the design engineer, energy dissipation can be achieved with the standard amount of rip rap at the outlet of the pipe and the additional rip rap lining of the tail ditch that is reflected in the current design. Section CB (Design Plans) Sheet 6-11 Station 250-272 Shift road alignment more to the West to reduce many small stream crossings into one large crossing. Response: This concern was resolved in a separate meeting on 2/10/00. Sheet 7 Station 255+20 Consider bridging to avoid impacts. Response: Alternate 1 would span all of the wetlands in this area and abridge/culvert cost comparison produced the following cost difference: Dual Bridges $7,750,000 vs. a single barrel culvert $220,300. (A difference of $7,529,700) Dual bridges would span all of the wetlands and save 0.59 ha (1.5 ac.) of wetlands. Alternate 2 would span the majority of the wetlands in this area and a bridge/culvert cost comparison produced the following cost difference: Dual Bridges $4,323,000 vs. a single barrel culvert $220,300. (A difference of $4,102,700) Dual bridges would span the majority of the wetlands and save 0.45 ha (1.1 ac.) of wetlands.
