Good afternoon Jeremiah and Lindsay,
The 15-Day As-Built/MYO review for the Hip Bone Creek Mitigation Site (SAW-2018-01160) ended
October 27, 2021. This review was done in accordance with Section 332.8(o)(9) of the 2008
Mitigation Rule. All comments received from the NCIRT are incorporated in the email below. Please
address IRT concerns in the MY1 Report and reply to this email. There were no objections to issuing
the initial (30% ) credit release of 997.920 warm SMUs and 1.389 riparian WMUs. Please find
attached the current signed ledger. The IRT is not requesting a site visit at this time.
USACE Comments, Kim Browning:
1. What was the minor change in wetland area due to miscalculation at the Mitigation Plan
stage?
2. Please notify the IRT once the fencing for the interior crossings has been installed.
3. Please provide a random transect of the vegetation in the enhancement wetlands at least
twice during monitoring.
4. 1 would recommend keeping an eye on the red maple in the vicinity of veg plots 3 and R4 in
future monitoring years.
5. Were soil borings collected near the installed wetland gauges (as per the 2016 IRT Guidance)?
Please submit this data with the MY1 report. It would have been helpful to include the

baseline data for the wetland gauges, if any were installed prior to construction.
USACE Comments, Casey Haywood:
If supplemental planting will be needed in the future, it is recommended to avoid American
sycamore and river birch due to their already high stem counts.
Overall, the report was thorough and well organized. Also appreciated the inclusion of the
drone footage.
DWR Comments, Erin Davis:
1. DWR appreciates the inclusion of the drone video. It was very helpful for this review. And it
was a bonus to see monitoring staff in action.
2. Were soil borings collected near the installed wetland gauges (as per the 2016 IRT Guidance)?
Please submit this data with the MY1 report.
3. Based on the plant list and veg plot data (many starting with only 4 or 5 species), DWR
recommends watching species diversity through monitoring and if any supplemental planting
is needed to take advantage of the opportunity to include additional species. Since sycamore
and river birch make up over 50% of planted stems, DWR requests that these species be
avoided in potential supplemental plantings or included only at very low percentages.
4. What were the final upstream and downstream elevations stream bed/embedded structure
for all culvert installations? Were there any deviations in the upstream/downstream structure
station numbers from the design plan? Ideally, DWR would like to see a redline of the
proposed crossing sizing table from the culvert details design plan sheet 5A.
5. Redline Sheet 3 — Based on the drone video, it appears the pond drainage rock outlet was
extended within the easement to approximately the first boundary bend (approximately 80-
100 feet). DWR believes this change warrants a redline callout.
USEPA Comments, Todd Bowers:
1. Missing fencing and landowner agreement was noted and KCI has stated that installation will
occur as soon as possible. Recommend sponsor notify the IRT when this occurs if significantly
before the MY1 Report is drafted.
2. Planting followed the plan very closely with just a few minor shifts in species stem
counts/percentages; all appear suitable and maintains a diverse mix of species.
3. 1 am concerned that the late date of planting (April 30, 2021) may incur a higher rate of
mortality than desired, especially in first growing season. Recommend the sponsor and IRT
pay particularly close attention to this in the upcoming MY1 report. This also pushes back the
MY1 monitoring to extremely late in the season.
4. All the photos of the streams, veg plots, and crossings are excellent. I also really appreciated
the cross section pages with data tables, charts and photo. Very well presented.
5. Thank you very much for posting the site -wide drone footage. I greatly appreciate this
information as I am currently unable to make site visits. This approach also provides a level of
detail that enhances the text and photos.
Please contact me with any questions.
Regards,

Kim
