Individual 404 Permit SAW 2001 20061 issued October 28, 2011
Dear Mr Matthews
The North Carolina Department of Transportation ( NCDOT) proposes a modification to
the existing Individual Section 404 Permit and Section 401 Water Quality Certification
for the above referenced project A revised impact summary table revised permit
drawings, modified EEP acceptance letter and a modified SHPO concurrence letter are
included with this letter The purpose of this letter is to request a modification to the
original permit due to a recent design change at Permit Impact Site # 4 The revised
design does not compromise NCDOT s compliance with the existing permit conditions
Dunng the course of preconstruction activities NCDOT found an error in the original
field notes that changed some stream elevations NCDOT has redesigned the culvert at
Site 4 based on the revised stream profile The new culvert design is the same size but
0 6 higher at the centerline of the roadway and on a slightly flatter grade than the
previously approved design The proposed construction revision will include a rock cross
vane upstream of the culvert inlet The purpose of the rock cross vane is to stabilize the

stream and avoid a potential head cut upstream and to allow for a stable transition of the
main channel and the tributary into the box culvert
In order to maintain adequate cover between the top of the culvert and the roadway, either
the roadway elevation would need to be raised or the above mentioned culvert revision
would be required Raising the elevation of the proposed roadway was determined not to
be feasible because Site 4 is too _close to the beginning of the-project-and existing
buildings The - design revisions -will increase-permanent stream 7impacts -by -13 feet due to
the culvert revision and decrease temporary stream impacts by 13 feet
Historic Architecture
The construction revision does occur within the proposed National Historic Boundary for
the Joseph Benjamin Neal House A meeting was held with representatives from NCDOT
and SHPO on November 29 2011 to review the proposed construction revision The
SHPO concurred that the construction revision will have no adverse effect on the historic
property A copy of the SHPO concurrence form is included with this letter
Compensatory Mitigation
Permanent stream impacts requiring mitigation have increased by 13 feet Attached to
this letter is a modified EEP acceptance letter to cover the additional stream mitigation
