Good afternoon all,
The 15-Day As-Built/Record Drawing review for the Groundhog Hollow Mitigation Site (SAW-2018-00450) ended July 16,
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 within this email. There were no objections to issuing the initial
30% credit release. Please find attached the current signed ledger. A site visit is not requested at this time.
DWR Comments, Erin Davis:
1. Regarding the May 2021 repairs, please callout the repair locations on the MY1 report CCPV.
2. If additional planting becomes an action item during the monitoring period, DWR requests that at least one or
two additional species be used to promote more diversity. Two of the fixed veg plots are starting out with only three
species present.
3. Please confirm there were no changes to the approved seed mixes.
4. Several of the pool cross section photos appear to show significant fine sediment present. Since January, have
you observed this material flushing through the project reaches? Do you expect the MY1 cross section data to deviate
substantially from MVO?
5. The Flow Gauge GF4-A photo shows a rock sill structure upstream. What is the drop depth from this structure?
Were there any concerns with how it was installed?
USACE Comments, Casey Haywood:
1. Appreciate veg plot 8 and random veg plot 2 being established in existing wetlands. Recommend including
wetland indicator status for planted stems in Table 7 in future reports.
2. Table 9. Veg plots 1, 2, 3, 6, & R1 are all meeting success, however the plots are dominated by a single species
and account for more than half of the planted stems. Okay with the addition of sugarberry to the planting plan species
list, but would encourage the addition of one or two species if a supplemental planting is needed in the future.
Please reach out if you have any questions.
Thanks
Kim
