Good afternoon all,
The 15-Day As-Built/Record Drawing review for the Perry Hill Mitigation Site (SAW-2019-00125) ended July 17,
2021. 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 within this email. There were no objections
to issuing the initial 30% credit release. Please find attached the current signed ledger. The IRT would like to
plan on a site visit in 2022.
DWR Comments, Erin Davis:
1. The redline drawings did not show any changes in the species/quantities installed from the mit plan
approved plant list and seed mixes. Please confirm.
2. In the mitigation plan review comments, the IRT expressed concern about UT1 Reach 1 flow. Based on
channel vegetation and dryness shown in the March/April photos and drone footage, DWR is still concerned
about flow for this reach at this time.
3. Besides lunker log, were any other stabilization treatment options considered before riprapping the slope
above UT1?
4. While photo points 7 and 8 are located in the vicinity of the Reach 4 crossing, the distance and angle
makes it difficult to get a clear view of the double culverts. Please add a photo point at the downstream
culvert crossing in future monitoring reports.
5. DWR appreciated the drone video provided. It was very helpful for this review. All of the wood added to
the channels looked great.
6. Drone video 15:52 - How are the logs laying above the brush anchored to the bank?
7. Drone video 25:14 - It appeared multiple log sills were notched, is this a common practice during initial
construction? Do notches typically extend across the majority of the exposed log?

USACE Comments, Casey Haywood:
1. I appreciate the consideration that was given to planting zones and having the wetland indicators listed for
planted species. The drone video was also helpful.
2. There are concerns about flow on UT1 R1. Stream photos and drone video indicated that the channel was
dry and it had grass growing throughout the entire channel.
Please reach out if you have any questions.
Thanks
Kim
