Subject: Application for Section 404 Nationwide Permit 14 and 401 Water Quality
Certification for the proposed replacement of Bridge No. 190002 on NC 141 over
Slow Creek in Cherokee County, Division 14, TIP No. BR-0011.
Debit $240 from WBS 67011.1.1.
Dear Madam:
NCDOT proposes to replace the structurally deficient Bridge No. 190002 on NC 141 over Slow
Creek in Cherokee County. The new bridge will be constructed in its existing location. Traffic
will utilize an onsite detour via a temporary bridge to be constructed just east of the existing bridge,
during the construction period.
The construction of the new bridge will require an existing 48-inch CMP to be slip -lined with a
42-inch steel casing, which will extend out to the -L- fill line. Initially however, the existing 48-
inch CMP will be extended with a temporary 42-inch out to the -L-DET fill slope to allow for the
construction of the temporary detour bridge and associated approach. After construction of the
new bridge and removal of the temporary detour bridge and its approaches, the fill will be pulled
back to the -L- line fill slope, the temporary 42-inch RCP will be removed, and the existing 48-
inch CMP will be slip -lined with the 42-inch steel casing, as mentioned previously.
The fill to Wetland WA for the construction of the temporary detour bridge and its associated
approach will be temporary. However, NCDOT has determined that even though the elevation
can be restored to the wetland, the compaction of the soils is likely to disturb the function of the
wetland. Therefore, all wetland fill impacts have been listed as "permanent" in the PCN, and
mitigation is provided for these impacts.

Total impacts for this project are 78 if of permanent stream impacts (70 if of fill, 8 if of bank
stabilization), 10 if of temporary steam impacts associated with the bank stabilization, 0.04 acre
of permanent wetland Ell, and <0.01 acre of wetland hand -clearing.
There will be no utility impacts for this project.
Mitigation
NCDOT proposes mitigation for the 70 feet of permanent stream impacts (excludes mitigation
for the 81f of bank stabilization impact) and 0.04 acre of permanent wetland impacts (excludes
mitigation for the 0.003 acre of hand -clearing impact) for this project. Mitigation has been
received from DMS.
Please see enclosed copies of the Pre -Construction Notification (PCN), DMS Acceptance Letter,
stormwater management plan, permit drawings and design plans for the above -referenced project.
A Minimum Criteria Determination Checklist was completed in May 2019 and distributed shortly
thereafter. Additional copies are available upon request.
This project calls for a letting date of April 21, 2020 and a review date of March 3, 2020.
A copy of this permit application and its distribution list will be posted on the NCDOT Website
