Subject: Application for Section 404 Nationwide Permit 14, and Section 401 Water
Quality Certification for the Proposed Replacement of Bridge 663 on SR 1002
(Traphill Road) over East Prong Roaring River in Wilkes County, Division 11, TIP
No. BR-0125, Debit $570 from WBS 48834.1.1.

Dear Madam:

The North Carolina Department of Transportation (NCDOT) proposes to replace bridge number 663 on SR
1002 with a new bridge to the east of the existing alignment. Traffic will be maintained on the existing
bridge during construction.

As a result of replacing the existing bridge, there will be 130 linear feet of stream bank stabilization under
the bridge and at new ditch outlets, and 0.02 acre of temporary stream impacts from floating turbidity
curtains needed for construction. As a result of the new roadway slopes associated with shifting the bridge
to the east, there will also be 225 linear feet of permanent stream impacts from relocation of an unnamed
tributary.

Required mitigation for this project will be provided by debiting the Idols Road Extension Mitigation Site
(ONEID 034-003).

The Idols Road Extension Site is located in Forsyth County within the USGS hydrologic unit 03040101 of
the Yadkin River. NCDOT acquired the site to mitigate for unavoidable, jurisdictional impacts associated
with TIP U-2707. Table 1 shows the final mitigation quantities approved for the site. Table 2 indicates all
mitigation debits that have occurred per regulatory agency approval.

In order to offset unavoidable impacts associated with BR-0125, NCDOT will be debiting the Idols Road
Ext site for 450 linear feet (225 linear feet @2:1) of stream mitigation. All debits associated with this
mitigation site are listed below.
