Subject: Request for Additional Information: R-3421AB , Richmond County
Chris,
The permit modification request for the subject project has been reviewed. For the review process to continue, please
provide the below additional information within 30-days. Your application is currently placed on hold until the following
information has been received:
Mitigation
1. NCDWR requires mitigation for losses greater than or equal to 300 linear feet of stream and one acre of
wetlands. Please provide a mitigation plan that conforms to the requirements of 15A NCAC 02H .500 for the
proposed project, specifically R-342113. The DMS Acceptance letter for the Section B is attached.
Stormwater
Section A: See attached revised SMP for Section A
1. The proposed impervious acreage is missing on the SMP.
2. The SMP narrative states that grass swales are proposed. The grass swale BMP sheet needs to be filled -out and
included in the SMP.

3. The SMP narrative states that there are not any direct discharges to JS streams, however numerous pipes
discharge directly to JS streams.
Section B: See attached revised SMP for Section B
1. The SMP narrative states that grass swales are proposed. The grass swale BMP sheet needs to be filled -out and
included in the SMP.
Permit dwg sht 43: The labels at the base of ramp B use the word "basin". Is this a SW treatment basin? We proposed
using the gore area as a basin, raising inverts of pipes, etc to get some infiltration and attenuate flow. However, we did
not do any routing/storage calcs and are not looking to get credit. Only proposed from practical design standpoint and
not for mitigation/credit.

R-3421A is an interchange and bypass project (US220 Bypass From US74 Bypass West Of Rockingham at SR1109 Interchange) which will include a 46' grass median with
2@12' travel lanes in each direction. The project also includes grass lined roadway ditches. The proposed project includes 4 major drainage structures (3Culverts & extension
of 2 culverts) located in the interchange, which will convey Un-named Tribs to the Pee Dee River. The culverts will include sills and utilize Low Flow Benches as well as a
stream relocation between 2 culverts to maintain the low flow in one barrel of the culvert. A Rip Rapped Energy Dissipator will be utilized at the outlet of 2 60" pipes to dissipate
the energy and prevent erosion to the receiving stream. There are some minor channel improvements at the inlet and outlet of a few of the culverts. Direct dischages into
jurisdictional features were avoided to the maximum extent practicable. Where possible, drainage systems were released away from jurisdictional features. However, in some
locations direct discahge was unavoidable due to extreme topographic constraints as well as proposed roadway profiles. In these locations no practical alternatives were
present.

Additional Comments
The design for R-3421A includes typical grassed cut ditches within the roadway footprint. These ditches are collecting runoff from the impervious roadway surfaces and transporting the runoff to inlets and pipes. The
geometry of the typical cut ditches contain side slopes ranging from 4:1 to 8:1 and having mostly mild longitudinal slopes. However, no grassed swale treatment was claimed nor regired for this portion of the project even
though many aspects of the grassed Swale criteria was incorporated into the design.

Subject: Mitigation Acceptance Letter:
R-3421B, US 220 Bypass, Richmond County
The purpose of this letter is to notify you that the Division of Mitigation Services (DMS) will provide the
compensatory stream and wetland mitigation for the subject project. Based on the information supplied by you on July 30,
2019, the impacts are located in CU 03040201 of the Yadkin River basin in the Southern Piedmont (SP) Eco-Region, and are
as follows:
Yadkin Stream Wetlands Buffer (Sq. Ft.)
03040201 Non- Coastal
Sp Cold Cool Warm Riparian Riparian Marsh Zone 1 Zone 2
Impacts (feet/acres) 0 0 3,611.0 3.80 0 0 0 0
*Some of the stream and/or wetland impacts may be proposed to be mitigated at a 1:1 mitigation ratio. See permit application
for details.
DMS commits to implementing sufficient compensatory stream and wetland mitigation credits to offset the impacts
associated with this project as determined by the regulatory agencies in accordance with the 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 DMS.
If you have any questions or need additional information, please contact Beth Harmon at 919-707-8420.
