Highway 70 Improvements Beaufort, Carteret County Federal Aid Project No STPNHF - 70(43) State Project No 8 1162501 WBS No 34528 1 1 February 3, 2012 The North Carolina Department of Transportation ( NCDOT) will perform on site mitigation for impacts associated with R 3307 Improvements to US 70 from existing four lanes at Radio Island to US 70 North of SR 1429 (Olga Road) The mitigation site is located dust north of the town of Beaufort along Turner Street adjacent to Town Creek The mitigation is proposed to restore 1 4 acres of salt marsh by causeway removal along Turner Street This mitigation will be used to offset the 0 66 acres of impacts to salt marsh at a 1 1 ratio associated with TIP R 3307 The residual restoration will be retained by the NCDOT as on site assets for future projects in the area Existing Conditions Turner Street is currently a two lane secondary road that crosses Town Creek approximately 300 feet south of West Beaufort Road Town Creek flows to the west under Turner Street through four 60 ft long 95 x 67 corrugated aluminum pipes To the south of the crossing a salt marsh wetland dominated by smooth cordgrass (Spartina alterniflora) runs along the both sides of the causeway and extends outward along Town Creek The Environmental Assessment (EA) dated October 2004 and the Finding of No Significant Impact (FONSI) dated August 2006 for TIP R 3307 provide further details concerning natural resource and roadway conditions Proposed Conditions The mitigation site will consist of 14 acres of salt marsh restoration at the proposed Turner Street Bridge The total restoration acreage will be confirmed with the as built survey after site construction is completed The NCDOT will remove the existing culverts and approximately 560 ft of causeway The causeway and any higher knolls within the right of way will be graded to a target elevation of 0 2 ft msl This elevation is slightly higher than the mean tide level and is within the range of elevations taken in the adjacent marsh The restoration area will be planted on three foot centers with smooth cordgrass The Natural Environment Unit shall be contacted to provide construction oversight to ensure that the wetland mitigation area is constructed appropriately cc Mr' Scott McLendon USACE Wilmington (w /o attachment) Mr Brian Wrenn NCDWQ (w /o attachment) Mr Rob Ridings NCDWQ
