Hi Ray,
Thanks for taking the time to provide supplemental information regarding hydrology on the site. I reviewed the
additional gauge data from 2021, taking into account that beaver management was implemented. I agree to move
forward with proposed changes in the attachment you provided. It will be essential to document hydrologic uplift in
the rehabilitation area around gauges 4 and 7. Please include a section in the mitigation plan that addresses potential
risks/corresponding adaptive management, especially with regard to beaver management. Lastly, please include a
detailed description of stream and wetland conditions, broken down by reach, in the mit plan. This really helps
document current conditions and room for potential functional uplift.
Please reach out if you have further questions.
Thanks
Kim

Kim - you provided the following comment on the Nesbit Mitigation Plan in January;
Section 3.6.1 and Appendix K: Given that wetland gauges 1 and 2 already meet hydrology performance

standards, rehabilitation is not appropriate in these two locations since functional uplift cannot be demonstrated.
Please change these areas to wetland enhancement at 2:1.
a. After a discussion with RS on January 8, 2021, it was discovered that beaver were trapped near gauges 1
and 2 which contributed to the increased hydrology. If you can demonstrate that the hydrology is in fact not meeting
performance standards prior to the final mitigation plan, these areas may be credited at the rehabilitation ratio of
1.5:1.
As a result of your comment and the 2020 gauge data, RS added three additional pre -construction gauges to the Site
to monitor the groundwater during the beginning of the 2021 growing season. Further, we implemented a beaver
management plan to trap and remove beavers during the winter of 2020/2021. As a result, all beaver were removed,
and no additional beaver recolonized the Site. I have attached a figure which identifies the location of the original
four gauges and the extra gauges installed. Also included in the attachment are the results of the groundwater
monitoring effort through May 1, 2021. Gauges 1, 5, and 6 recorded groundwater within 12-inches of the surface for
60 consecutive days. Subsequently, we agree with your comment and plan to modify the mitigation
approach/crediting in these areas to Wetland Enhancement at a 2:1 ratio. Though gauge 7 recorded groundwater
within 12 inches of the surface for 37 days in 2021, we feel restoration of the stream through this area will
drastically increase the hydroperiod around gauges 7 and 4 - gauge 4 recorded nine days of saturation in 2021 vs. 29
days in 2020. Thus, we feel wetland rehabilitation crediting is still appropriate within this area. The last pages of the
attachment are a revised Restoration Plan (Figure 6), which shows wetland enhancement areas and the credit table
from our original submittal, and a proposed credit table including wetland enhancement.
Before submitting the final mitigation plan and applying for permits, I wanted to share this data and our revised
crediting with you for approval/concurrence. If you have any questions or would like to discuss, please feel free to
give me a call directly.
Sincerely,
Raymond H.

Good afternoon,
We have completed our review of the Draft Mitigation Plan for the NCDMS Nesbit Mitigation Project (SAW-2019-
00832). Please see the attached memo, which includes all NCIRT comments that were posted on the DMS
SharePoint site during the review process along with additional comments provided by Wilmington District staff
following our review of the IRT comments.
We have evaluated the comments generated during the review period, and determined that the concerns raised are
generally minor and can be addressed in the final mitigation plan. Accordingly, it is our intent to approve this Draft
Mitigation Plan (contingent upon the attached comments being addressed in the Final Mitigation Plan) unless a
member of the NCIRT initiates the Dispute Resolution Process, as described in the Final Mitigation Rule (33 CFR
Section 332.8(e)). Please note that initiation of this process requires that a senior official of the agency objecting to
the approval of the mitigation plan (instrument amendment) notify the District Engineer by letter within 15 days of
this email (by COB on January 29, 2021). Please notify me if you intend to initiate the Dispute Resolution Process.
Provided that we do not receive any objections, we will provide an approval letter to NCDMS at the conclusion of
the 15-day Dispute Resolution window. This approval will also transmit all comments generated during the review
process to NCDMS, which must be addressed in the Final Mitigation Plan to be submitted with the Preconstruction
Notification Application for NWP 27. All NCIRT members will receive a copy of the approval letter and all
comments for your records.
Thank you for your participation.
