Do not click links or open attachments unless you verify. Send all suspicious email as an attachment to Report Spam. Good afternoon Paul, The 15-Day As-Built/MYO review for the Round Hill Branch Mitigation Site (SAW-2018-01168) ended June 25, 2022. 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. There were no objections to issuing the initial (30% ) credit release of 642.600 SMUs. Please find attached the current signed ledger. The IRT is not requesting a site visit at this time. USACE Comments, Kim Isenhour: 1. What is the total area of floodplain scour that you refer to as vernal pools that enhance ecological function to the site? Will these areas be planted with herbaceous cover to prevent further scouring, and will these areas be re -planted with woody species as described in the final mitigation plan? 2. Please inform the IRT once the fencing encroachments have been resolved. 3. Although the snow-covered photos are aesthetically pleasing, please provide photos that show the condition of the buffer and stream banks in future reports. 4. Please provide an additional photo for the crossing where photo point 1 is located, from the perspective of looking upstream at the crossing (position yourself near STA 14+00). Both photos of this crossing show the gates open, so livestock access to the ford crossing is a concern. NCDWR Comments, Erin Davis: 1. DWR was glad that the two easement dispute areas were identified early. We encourage making every effort to resolve these issues prior to the 2023 credit release meeting. 2. DWR requests photos of the floodplain scour area and the drainage swale feature be included in the MY1 report. 3. Please show all existing wetland areas within the project easement on future CCPV figures. 4. Given that the as -built survey was performed in May 2021 and long. profile surveyed in August 2021, it would've been helpful to include supplemental non -snow covered project photos in the MYO report. Please make a note for future projects. 5. DWR appreciated that DIMS' site visit comments (and KCI's responses) were included for this review. DWR is ok with the proposed credit release. No site visit requested. USEPA Comments, Todd Bowers: There were a few, relatively minor deviations from the original design plans; primarily these were due to adjustments due to bedrock encountered during construction. Many planted species were not identified during vegetation monitoring due to monitoring during dormancy. This resulted in fewer species than planted noted on some of the veg plots. No comment as this will be corrected in the coming MY survey. No adaptive management plan needed at this time. No issues of conservation easement encroachment however there are two areas where fencing and conservation easement boundaries are being actively addressed with the adjoining landowners. I recommend adding the pool adjustments made (due to bedrock) to the longitudinal profile for comparison of design and actual. Noted locations at T1 (sta.10375), and missing pools on RHB (stas. 1080, 1290 and 1340). I noted a slight discrepancy in the stream credits calculated in Table 1. The As -Built length of streams is 2,242 feet and the length of streams removed for credit due to crossings is 114 feet. This results in a final credit amount of 2,128 cool SMUs. It appears that the stream segments removed from credit are tallied from the Original Mitigation Plan lengths (2,256 —114 = 2,142). Recommend KCI take another look at these totals and correct if necessary. Overall, I am very satisfied with the report and the work that KCI has completed at the site. Having not been able to visit this location, I really appreciated the detailed ground -level stream and veg plot photos to illustrate the amount of work implemented. I recommend the appropriate credit release (Milestone 2) for cool stream mitigation units for this monitoring milestone. I have no other substantial comments at this time. Please reach out with any questions.
