Dear Ms. Homewood:
Thomas Brown
East Division Wetland Specialist
Please reference the Request for Additional Information from your office, received by email on
June 17, 2022, associated with SWR#20220241. A response to the request can be found below,
with the questions/comments from the request underlined.
1. With regards to the stream relocation around the North Pit the plans appear to indicate that
the tie-in locations with the existing stream may occur at angles close to 90 degrees. Please
either provide more detailed scaled drawings of the proposed tie-ins so that we may evaluate
any concerns for instability caused by extreme radii of curvature or provide assurances that a
qualified individual will oversee the construction of the relocation channel. [15A NCAC 02H
.0506(b)1
Please see the attached updated channel design showing the gradual tie-in angles. The
entire channel will be constructed and stabilized before it is tied into the existing
channel. Both Phillip Pressley, Sr. Environmental Engineer, Martin Marietta, and myself,
will oversee the construction, stabilization and tie-in of this channel.
2. With regards to the detailed culvert design drawings provided, the plans state that the
culverts will be installed in the dry, however the Division's previous request on March 23, 2022
specifically requested "a detailed construction sequence demonstrating that the construction
will be conducted "in the dry" and showing limits of all erosion control measures necessary to
protect the adjacent wetlands." The statement provided on the plan sheet is not specific
enough for the Division to evaluate whether the construction sequence and construction
activity will cause or contribute to any water quality standard violations (wetland violations).

Please also clarify if any additional vegetation clearing will be needed adjacent to the proposed
road for construction access. [15A NCAC 02H .0506(b)]
The Culverts on the proposed roads will be installed in the dry. If required, sandbagging
the stream and pump around method will be used in order to assure work is completed
in the dry. As shown on the plans provided in the application, the culvert within the
stream channel will be buried 1ft to allow aquatic life passage. All other culverts will be
installed with the bottom at approximately existing grade. The road will be constructed
using clean material which will be stabilized by seeding and appropriate erosion control
measures. Culverts will be properly bedded and the road will be compacted as it is
constructed. There will be no clearing of vegetation within wetland areas outside of
permitted impact areas. Stormwater and erosion control measures will be installed as
required by NC DEMLR.
3. The proposed mitigation plan includes preservation of the Woods Tract. You state that the
"main current threat" to this land is timbering, however the Division is unclear how donation of
this land to the Forest Service removes this threat or how donation to the Forest Service
provides perpetual conservation of this wetland. Please provide further specifics and detailed
assurances regarding the long-term protection of this property. Upon receipt of this
information the Division will need to confer with the Interagency Review Team agencies to
evaluate whether the proposed preservation can be considered as a valid part of your proposed
mitigation plan. [15A NCAC 02H .0506(c)1
Martin Marietta is currently working with The Coastal Land Trust and The Nature
Conservancy to preserve the Woods Property in perpetuity. Details of this preservation
will be provided to the DWR as soon as possible.
We appreciate the opportunity to respond to this request. Please feel free to contact me by
phone or email at any time for any additional information or clarification.
Sincerely,
Thomas Brown
East Division Wetland Specialist
