Good Morning Kim!
I just wanted to send a quick note to acknowledge the receipt of the IRT's comments in reference to the Key Mill
Mitigation Site's As -built Baselined Monitoring Report and Record Drawings. We have reviewed them and will
incorporate our responses in the MY1 Report, as requested. In addition, Wildlands will include a copy of the email
received with the IRT's comments in the Appendix of the report. If you have any questions, please feel free to contact
me either by phone or email. Thanks!
Sincerely,
Kristi Suggs

Good afternoon,
The 15-Day Record Drawing review for the Key Mill Mitigation Site (SAW-2017-01504) ended November 11, 2020. Per
Section 332.8(o)(9) of the 2008 Mitigation Rule, this review followed the streamlined review process. All comments
received from the NCIRT are incorporated in this email. Please address IRT concerns in the MY1 Report. There were no
objections to issuing the initial credit release. Please find attached the current signed ledger.
DWR comments, Erin Davis:
1. In the IRT mitigation plan review, Mac echoed DMS' comment regarding the usage of log sills on steeper gradient
tributaries with consideration for long term channel stability. WEI's response was to revise construction plans to
incorporate more boulder sills. Given the high number of substitutions back to log sills, DWR's concern still stands. These
areas should be closely inspected during monitoring for signs of instability.
2. DWR is ok with the planted material species and quantity substitutions, except for green ash. If green ash
dominated areas establish during monitoring (based on plot data and site visit observations), DWR may request
supplemental planting based on long term canopy closure concerns due to the emerald ash borer.
3. DWR does not believe the change in planted area warrants a reduction in ratio of credits. However, if construction
equipment used for the restoration reach entered the forested buffer, then the area should be monitored for signs of
woody vegetation stress/death and supplemental planted as necessary.
4. There appears to be multiple riprap swales/outlets shown on the record drawings but not the approved mitigation
plan design drawings: Sheet 1.6— BMP outlet near 155+00 and floodplain riprap near 155+75, Sheet 1.7—vernal
pool/BMP outlet near 159+75, and Sheet 1.9 — outlet near 165+75. Please call these areas out on future redline
drawings and provide a justification for the hardening measure in the baseline report.
Please contact the mitigation office if you have questions.
Have a good weekend,
Kim
