This mitigation acceptance letter replaces the mitigation acceptance letters issued on July 27 and
October 27, 2011 EEP commits to implementing sufficient compensatory stream riparian and non riparian
wetland mitigation credits to offset the impacts associated with this project in accordance with the N C Department
of Environment and Natural Resources Ecosystem Enhancement Program In Lieu Fee Instrument dated July 28
2010 If the above referenced impact amounts are revised then this mitigation acceptance letter will no longer be
valid and a new mitigation acceptance letter will be required from EEP

Turner Street Marsh Restoration Plan (REVISED)
R -3307, 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
