Re: MY2 Credit Release of the RES Yadkin 01 Umbrella Mitigation Banking Instrument and
Twiman Mitigation Site; SAW-2017-01467

Dear Mr. Breslow:
This correspondence is in reference to the Monitoring Year 2 (MY2) Report dated
September 14, 2022, submitted in support of your request for the fourth credit release for the
Twiman Mitigation Site. The 30.5-acre Twiman Mitigation Site is part of the RES Yadkin 01
Umbrella Mitigation Bank, located approximately two miles southeast of Booneville, in Yadkin
County, North Carolina. An easement change after final plan approval, reduced the project by
178 linear feet or 35.933 Stream Mitigation Units (SMU's), bringing the total stream restoration
and enhancement potential for the project to 5,812.067 warm SMU's along seven unnamed
tributaries that drain to North Deep Creek in the Upper Yadkin Watershed of the Upper Pee Dee
River Basin (03040101). The purpose of this letter is to confirm the MY2 release of credits for
this mitigation site.
Pursuant to the Mitigation Banking Instrument (UMBI) entitled, Agreement to Establish
the RES Yadkin 01 Umbrella Mitigation Bank, approved December 4, 2019; and the site -specific
Twiman Final Mitigation Plan dated August 2019, ten percent (10%) of the mitigation site's total
restoration and enhancement credits shall be available for sale after submittal of the MY2
monitoring report, provided the channel is stable and upon completion of the required tasks
pursuant to the Mitigation Plan.
By copy of this correspondence, we confirm that you have satisfied the above
requirements for the third credit release for all parcels within the bank; and 581.207 SMU's
constituting 10% of the mitigation site's total restoration and enhancement credits are now
available for sale.
Although the IRT did not visit this site as part of the MY2 evaluation, we have reviewed
the Year 2 Monitoring Report and offered the following comments.
Erin Davis (NCDWR) comments:
1. DWR appreciates the update on the proposed NCDOT encroachment.
2. We support the addition of buttonbush to the approved site plant list. Is it possible

moving forward to add a note to Table 5 listing additional supplemental plant
species so all approved species can be found in a single place? (This
question/request is for all bank site monitoring reports.)
3. DWR is glad that low species diversity is on your radar because we are concerned
with the veg plots reporting only 2-3 species.
DWR is not requesting a site visit. We support the proposed credit release.
Steve Kichefski (USACE) comments:
4. Concur with DWR comment regarding increasing species diversity. Consider this
with the proposed 2022 supplemental planting.
5. Please continue to track the progress of repair areas and previous IRT comments
through future monitoring reports.
RES has requested an M&M bond reduction for SUR0069944. The revised penal sum at
Year 2 credit release should be $150,310 per the bond reduction schedule for a reduction amount
of $25,052. We concur with the bond reduction according to the schedule approved with the final
mitigation plan.
Thank you for your time and cooperation. If you have any questions, please contact
Steve Kichefski at [phone] extension 4234.
Sincerely,
Steve Digitally signed by Steve
