23) There shall be no clearing of wetlands outside of the areas indicated on the attached workplan drawings
without prior approval from DCM. Wetland areas to be temporarily impacted by hand clearing shall not
be grubbed. Hand clearing in Coastal Wetlands shall be reduced to the maximum extent practicable.
24) Construction mats shall be utilized to support equipment within wetland areas to minimize temporary
wetland impacts. These mats shall be removed immediately following project completion.
25) The permittee shall minimize the need to cross wetlands in transporting equipment to the maximum
extent practicable.
26) Upon completion of construction, the permittee shall schedule a meeting with DCM to verify the extent
and location of temporary impacts.
27) Due to the possibility that excavation, hand clearing, and/or other site alterations might prevent the
temporary Coastal Wetland impact areas from re -attaining pre -project wetland functions, the permittee
shall provide an annual update on the Coastal Wetland areas temporarily impacted by this project. This
annual update shall consist of photographs and a brief written report on the progress of these temporarily
impacted areas in re -attaining their pre -project wetland functions. The permittee shall schedule a
meeting with DCM to verify the extent and location of temporary impacts upon project completion.
Within three years after project completion, the permittee shall hold another agency field meeting with
DCM to determine if the Coastal Wetland areas temporarily impacted by this project have re -attained
pre -project wetland functions. If at the end of three years DCM determines that the Coastal Wetland
areas temporarily impacted by the project have not re -attained pre -project wetland functions, DCM will
determine whether compensatory wetland mitigation shall be required.
On site Coastal Wetland Mitigation
28) Unless specifically altered herein, in accordance with commitments made by the permittee, and in order
to mitigate for the anticipated wetland impacts associated with the project, on -site mitigation to restore
approximately 0.4 acres of existing high ground area to Coastal Wetlands shall be carried out as
described in the document titled: "Onsite Wetland Restoration Plan at Bridge No. 15 over the Calabash
River on NC 179 Brunswick County", dated 10/12/22, and also the email from the permittee dated
2/16/23. Any subsequent changes to the mitigation plan authorized by this CAMA permit shall require
additional DCM authorization.
29) The wetland restoration area shall be fully contained by silt fence and/or turbidity curtain until all of the
unsuitable fill material has been removed and the restoration area has been restored to the approximate
natural elevation of the adjacent, similar, and undisturbed wetlands and stabilized with appropriate
coastal wetland vegetation.

years after mitigation site construction, or until mitigation success criteria are met. Annual monitoring
reports shall include photographs and an assessment of whether the site is achieving success. Progress
reports shall also be provided upon request. Monitoring may cease if the permittee can demonstrate that
the site has been successfully restored by achieving success criteria and written concurrence is received
from DCM. The vegetation component of the onsite Coastal Wetland mitigation shall be considered
successful when the target wetland herbaceous species survives and has an average of 75 percent
vegetative cover, not including any invasive species.
32) Additional mitigation or other remedial actions may be required for permanent impacts to Coastal
Wetlands if the mitigation site fails to meet its mitigation success criteria within 5 years of its
construction.
NOTE: Approximately 0.3 acres of the 0.4 acres of onsite Coastal Wetland mitigation will be under the
new bridge, and will therefore not require vegetation planting and monitoring.
33) The mitigation site shall be protected in perpetuity in its restored state according to the approved final
mitigation plan and owned by the permittee or its approved designee. Failure to adequately protect the
mitigation site may result in further mitigation requirements.
34) In accordance with commitments made by the permittee, the onsite Coastal Wetland mitigation shall not
generate any excess mitigation credits for use on future projects.
Utility Impacts
NOTE: Construction of the new bridge will also require relocation of utilities.
35) The authorized utility relocations shall not result in any permanent or temporary impacts to wetlands or
waters of the State, without permit modification.
36) Any utility work associated with this project that is not specifically depicted on the attached workplan
drawings, or described within the attached permit application, shall require approval from DCM, either
under the authority of this permit, or by the utility company obtaining separate authorization.
