The FINAL As -Built Baseline Monitoring Report (MYO) and Record Drawings for the Warren Wilson College Site (DMS#
100019) were received by DMS on September 1, 2020 and posted to the IRT SharePoint site and DWR Laserfiche on
September 4, 2020 for your review.
2020 is Monitoring Year 1 for this project. Restoration Systems and DMS are requesting a mitigation plan addendum for
a reduction in mitigation credit on the site (-176.2 cold SMUs). The mitigation plan addendum memorandum is attached
and is also included in the MYO report after the cover.
Upon IRT approval of the mitigation plan addendum, DMS will generate a credit ledger and will forward it to the IRT for
review and approval.

NCIRT Memorandum
Subject: Mitigation Plan Addendum
Warren Wilson College Stream Mitigation Site
DMS Contract #: 7188
DMS Project ID: 100019
RFP # 16-006991
USACE: SAW-2017-01557
NCDWR: 20171158
Dear NCIRT Members,
The As -built Cold Stream Mitigation Units (SMU) for the Warren Wilson College Site located in the French
Broad 06010105 have decreased from the IRT approved Mitigation Plan. Accordingly, Restoration
Systems and DMS are requesting a mitigation plan addendum for the asset reduction.
Mitigation Plan assets: 10,227 SMUs
As -Built assets: 10,050.933 SMUs
The stream mitigation assets have decreased due to the widening of permanent crossing widths on several
reaches to encompass the full pipe lengths and accompanying rock aprons for future maintenance needs.
This was not fully noticed until As -built surveys were performed. After discussions with the College's Dean
of Land Resources (Dave Ellum), DMS Western Regional Supervisor (Paul Wiesner), DMS Stewardship
representatives, and the NC State Property Office; it was decided that the best remedy for the
encroachment was to widen the conservation easement breaks on the affected crossings. These
permanent amendments to the conservation easements will continue to protect the Site while keeping
the College's ability to maintain the crossings in the future. The conservation easement modification is
currently underway and will be completed as quickly as possible. The amended crossings and locations
are documented in the MYO report and As -built record drawings.
The following table is from the Table 1. Project Mitigation Assets and Components in the MYO As -built
Report. The Mitigation Plan Footage/Acreage column represents proposed assets and the Restoration
Footage/Acreage column represents the updated assets. The comment column has the new linear feet of
channel that are outside of the conservation easements. The streams in these reaches have been restored,
stabilized, or are in culverts.
Please let us know if you have any questions, comments or concerns.
