Subject: Application for Section 404 Nationwide Permit 13 and 33, and 401 Water
Quality Certification for the proposed replacement of Bridge No. 166 on SR
1601 (Coolbrook Road) over Rocky Creek in Iredell County, Division 12, TIP
No. BR-0115.
Debit $240 from WBS 48824.1.1.
Dear Madam:
NCDOT proposes to replace structurally deficient Bridge No. 166 (superstructure condition
appraisal of 4 out of 9 according to Federal Highway Administration [FHWA] standards) on S.R.
1595 (Coolbrook Road) over Rocky Creek in Iredell County. The existing bridge is approaching
the end of its useful life. The existing bridge also has a posted weight limit, and the proposed
project has been designed to meet the legal load rating.
The project proposes replacing the existing two-lane bridge with an approximately 30-foot wide
structure with two 10-foot travel lanes with 3-foot 11-inch paved shoulders. The proposed bridge
would be approximately 138 feet in length and the proposed right of way varies from 60 feet to 85
feet. The total length of the project is approximately 700 feet. The proposed bridge will not be
posted and will be designed to meet the legal load rating. This bridge replacement will be
constructed in -place using an off -site detour.
There will be a total of 104 linear feet (If) of bank stabilization impacts. There will be a total of
115 if (<O.01 acre) of temporary impacts from impervious dikes located on both the left and right
banks of Rocky Creek; however, all but 11 if are within the bank stabilization impacts. There will
be 84 if (0.03 ac) of temporary impacts and from temporary work pads/causeways, if needed, all
of which are within the bank stabilization/impervious dike impacts.
There will be no utility impacts for this project.

Avoidance and Minimization
NCDOT has avoided permanent stream impacts to Rocky Creek (other than bank stabilization)
by spanning the creek with the bridge. The only permanent stream impacts will be those for
bank stabilization under the new bridge.
Mitigation
NCDOT does not propose mitigation for the 104 linear feet of bank stabilization impacts, as
bank stabilization does not require fill in the streambed and therefore, under Section 404 of the
Clean Water Act, does not constitute Loss of Waters of the U.S. and is not subject to
compensatory mitigation.
Please see enclosed copies of the Pre -Construction Notification (PCN), stormwater management
plan, permit drawings and design plans for the above -referenced project.
A Categorical Exclusion was completed in July 2019 and distributed shortly thereafter. Additional
copies are available upon request.
This project calls for a letting date of July 21, 2020 and a review date of June 2, 2020.
A copy of this permit application and its distribution list will be posted on the NCDOT Website
at: http://connect.ncdot.gov/resources/Environmental. If you have any questions or need
additional information, please contact Bill Barrett at [e-mail] or [phone].
