CCPV shows supplemental plantings dated 2016 and 2018. Please revise and/or update report discussion to include all supplemental plantings. A short discussion regarding size, quantity and species would be helpful. Did the planting that occurred in 2018 affect the outcome of the vegetation plot totals? Is the 2016 planting referring to the 2015 effort, or was this a separate supplemental planting? ➢ The reference to a 2015 planting was a typo. The only supplemental plantings that occurred on site were in 2016 and 2018. This error has been corrected and a brief description of the extent of each planting has been added to the report. No new stems were reported in any of the veg plots in 2018. • Is the "Total Cross-section Area" measurement the previous method used to determine area? The report indicates that this is a new metric. A short explanation in the report about this metric would help clear up any confusion. Please list the fixed elevation used for the measurement on the graph and/or table for each cross-section. ➢ Total Cross-section Area represents the previous method used to determine area (i.e. area under the baseline bankfull elevation). A short explanation of this has been added to the report and Table 11 has been updated with the baseline bankfull elevation for each cross- section. • Update Table 2 to include all supplemental plantings.. ➢ Table 2 has been updated.

Please show this area on the CCPV and include the treatment date if it has occurred on Table 2. ➢ This area of privet was treated on December 13, 2018. This date has been added to Table 2 and the area has been added to the CCPV. • A large tree fell and damaged portion of the fence on T2. Has this tree been removed and the fence repaired? ➢ The area around the tree is currently too wet to access and so the tree has not been removed. Once the area dries out, KCl will remove the tree and repair the fence. The landowner does not have his cows in this area of his pasture and has said he will keep the cows away from this area until the fence is repaired. • Table 11 c (T2) is missing the Total Cross Section Area line as shown on Table 11 b (T1). Please update. ➢ This table has been updated. Please contact me if you have any questions or would like clarification concerning these responses.

Construction was completed in November 2013. The site includes the restoration of 4,484 linear feet of restoration and 109 linear feet of enhancement on four tributaries to Irish Buffalo Creek in the Yadkin -Pee Dee River Basin. The project is located west of China Grove and north of Kannapolis off of Saw Road in Rowan County (Figure 1, Appendix A). This project will expand aquatic and terrestrial habitat in the Rocky River Watershed (03040105). The project is within the 03040105020040 Irish Buffalo Creek Local Watershed Unit (14 -digit HUC) (NCDENR, EEP 2009). In DMS' most recent publication of excluded and Targeted Local Watersheds/Hydrologic Units, the 03040105020040 14 -digit HUC has been identified as a Targeted Local Watershed. The project is located in the Piedmont Physiographic Province and the project streams initiate as headwater systems out of moderately -sloped, forested hills before reaching the floodplain of Irish Buffalo Creek. The site's 0.72 -square mile watershed is mostly pasture and mixed hardwoods with small pockets of rural residential development. Prior to construction the site was actively used for timber and cattle production for over five generations. The project goals and objectives are listed below. Project Goals • Restore a diverse riparian corridor that connects forested stream systems upstream and downstream of the project. • Reduce the sediment supply entering Irish Buffalo Creek. Project Objectives • Restore stable channel planforms to streams that have been straightened and modified. • Reshape and stabilize eroding stream banks. • Plant the site with native trees to help reestablish a diverse riparian corridor. • Install exclusion fencing and alternative watering options to keep livestock out of the project streams. During the Proposal Stage of the project, Reach T2 -A was identified as Enhancement Level 1 at a 1.5:1 credit ratio. During the assessment and design stage for this reach, a more aggressive restoration approach was determined to be need, and the because of this the decision was made to completely change the stream type from a G -type channel to a C/B type channel. This required a restoration level approach during construction and because of this KCI requested a reallocation of credit type from the IRT from 1.5:1 to 1:1. After several meetings and discussions with the IRT, this reallocation of credit type was agreed to and resulted in an increase of 155 credits from the credits listed in the mitigation plan. See Appendix F for more information on this change. Vegetation success is based on the criteria established in the USACE Stream Mitigation Guidelines (2003). This document states that vegetation monitoring results should have the following planted stem density minimums in the corresponding monitoring years: 320 stems/acre through Year Three, 288 stems/acre in Year Four, and 260 stems/acre in Year Five. The fifth -year vegetation monitoring was based on the Level 2 CVS-EEP vegetation monitoring protocol. The site's average density for this monitoring period is 392 planted stems/acre, with none of the plots having live stakes planted in them. Ten of the thirteen plots had greater than 260 planted stems/acre. There are three monitoring plots that have calculated planted stem densities less than 260 stems/acre; (Plots 3, 4, and 6). To ensure continued vegetative success, some parts of the site received supplemental planting in early 2016. This consisted of 80 one gallon size trees and approximately 1,400 bare root trees spread across the lower third of both tributaries. An additional supplemental planting occurred in early 2018, consisting of approximately 320 one gallon Jacob's Landing Site KCIAssociates of North Carolina DMS Project # 95024 1 2018— MY05 size trees spread primarily along the left bank of Tributary 2. See the Current Condition Planview in Appendix B for the locations of these plantings. Including volunteers, the monitoring plots averaged 1,055 total stems/acre. Fifth -year monitoring found the Jacob's Landing Site to be stable, with only minor changes from the as -built conditions. Two small areas of bank erosion that were reported on T 1 during MY02 were repaired with soil lifts in the beginning of 2016 and these have shown no signs of instability since. The monitoring components were installed in February/March 2014. Two automatic recording gauges have been installed along T1 and T2. Both stream gauges recorded several bankfull events during 2018. The monitoring plan for each tributary is as follows: T1 has a 1,500 foot longitudinal profile, 3 riffle cross-sections, and 1 pool cross-section; T2 has a 1,500 foot longitudinal profile, 5 riffle cross-sections and 2 pool cross-sections; T1A and T2A are being monitored visually since they are short reaches and small channels. Pebble counts were conducted at all eleven cross-sections. Ten permanent photo reference points have been established with a total of twenty-two photos to be taken annually. The fifth year of monitoring found the site to be functioning and T2 shows little change from the baseline conditions. While T 1 has several areas of stream bed aggradation, this is not seen as problematic, but rather the natural transfer of sediment through the system. Across the five years of monitoring, a clear pattern of sediment aggradation and transport through the system has been seen and this latest evidence of aggradation is believed to be a natural part of that cycle. Summary information/data related to the occurrence of items such as beaver or encroachment and statistics related to performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the Baseline Monitoring Report and in the Mitigation Plan documents available on the DMS' website. All raw data supporting the tables and figures in the appendices are available from DMS upon request. 2.0 METHODOLOGY The survey data were collected using a real-time kinematic GPS instrument between December 17 and 19, 2018. Based on feedback from the IRT and DMS, the cross-section measurements have been reviewed and have been updated. These measurements are now calculated by adjusting the bankfull elevation so that the cross-sectional area remains the same throughout the monitoring period. A metric called total cross-sectional area has been added that shows the cross-sectional area based off of the baseline bankfull elevation. The CVS-EEP protocol, Level 2 (http://cvs.bio.unc.edu/methods.htm) was used to collect vegetation data from the site. The vegetation monitoring was completed on July 27, 2018. 3.0 REFERENCES Lee, M.T., R.K. Peet, S.D. Roberts, and T.R. Wentworth. 2008.

During this meeting KCI presented a request to modify the allocation of stream mitigation credits on the Jacob's Landing stream restoration project. Citing procedural reasons, the IRT requested that KCI submit a formal request to reallocate credits. This letter will serve as that request. Request KCI requests the following changes to the credit table provided in the Jacob's Landing Stream Restoration Site - Final Mitigation Plan dated September 2012 (requested changes shown in red).

As a matter of practice, KCI attempts to be consistent with the credit -types requested in the Proposal during the assessment and the design stages of the project. During the assessment and design stage for Reach T2 -A, a more aggressive restoration approach was determined to be needed. This was primary due to the confinement of the valley, the difficulty of access, the absence of a functional floodplain and the poor condition of the valley walls leading down to the stream. These reasons and others resulted in ultimate decision to completely change the stream type from a G -type channel to a CB -type channel. This approach was in fact a restoration approach, although it never was properly identified as such in the Mitigation Plan. The approach included the following restoration initiatives: 1. Channel type changed from a G4 channel to a C4/134 channel by installing a typical riffle cross section with a 3.6' bankfull bench and a 0.9' bank height. 2. Adjusted thalweg and centerline (planform) slightly throughout the reach to allow for the incorporation of the bankfull bench. Bench location and width varied from cross section depending on condition of valley and the ability to accommodate the full bankfull width given the valley condition. 3. Installed significant number of structures (5 step pools, 8 riffle grade controls, 8 riffle enhancements) to stabilize the profile and create in -stream habitat. 4. Added bedform diversity and stabilized the planform. 5. Stabilized the valley walls and contributing drainage features. All of the items mentioned above support the reallocation of credit type to restoration (or enhancement at a higher ratio). KCI requests that the IRT support the correction of the 1.5:1 Enhancement I ratio KCI ASSOCIATES OF NORTH CAROLINA, P.A. www.kei.com Employee -Owned Since 1988 proposed for Reach 2A in the Final Mitigation Plan to 1:1 ratio. KCI can provide amended copies of the Mitigation Plan, if desired. We hope you find this information appropriate in order to move forward with your decision.

NORTH CAROLINA 28403-1343 REPLY TO r ATTENTION OF: September 2, 2014 Regulatory Division Re: Request for Modification to the Jacob's Ladder and Jacob's Landing Mitigation Sites (USACE AIDs 2012-01007 and 2012-01006) Mr. Tim Baumgartner North Carolina Ecosystem Enhancement Program 1652 Mail Service Center Raleigh, NC 27699-1652 Dear Mr. Baumgartner: Please reference the North Carolina Interagency Review Team (IRT) meeting of May 13, 2014, during which we discussed the Jacob's Ladder and Jacob's Landing stream mitigation projects. The discussion dealt with a request by NCEEP to the U.S. Army Corps of Engineers, Wilmington District (District) to modify a reach within each project resulting in a change in the mitigation approach and associated credit. During the IRT meeting, we asked that a written request be submitted to provide information on the specifics of each project modification so that the IRT could review the requests and provide comment back to us. Two letters dated May 22, 2014, were prepared by the project provider (KCI, Inc.) and distributed to the IRT. The following responses were received from the IRT agency members: Travis Wilson, North Carolina Wildlife Resources Commission, 5/29/2014: A switch from enhancement to restoration should have been addressed earlier during design. As I understood it during the presentation most of the design elements outlined in the modification request were incorporated under the enhancement level and only slight changes occurred during construction, and I don't want to establish a practice where the IRT is constantly reviewing requests from providers on a credit hunt to cover contractual deficiencies. However, with that said, I agree the improvements on the two subject reaches are consistent with a restoration approach, and if successful it will provide a restoration level of uplift. WRC does not object to the modification request. 2. Eric Kulz, North Carolina Division of Water Resources, 5/29/2014: The approaches described in the mitigation plans for the referenced reaches were fairly non - quantitative and appeared to represent an Enhancement I approach, which was approved by the IRT. The activities conducted appeared consistent with the descriptions of mitigation measures proposed in the approved mitigation plans. Again, the mitigation plans were not quantitative in nature, and E1 spans a wide variety of mitigation treatments. During the analysis phase of these projects, if the provider and EEP felt the initial assessment and proposal were incorrect/inappropriate, consultation with the IRT and re -review of the project stream conditions and mitigation approaches should have been requested and approval of revisions sought (note process taken with the Pancho bank site). Minor adjustments often occur during construction and are expected, and are described in the as - built report. Linear footage/acreage of mitigation and associated credits are then normally finalized. However, in this case changing the name of the mitigation approach and associated credit after construction does not appear warranted as the activities conducted appear to be fairly consistent with what was described in the approved mitigation plans. In addition to the responses above, we conducted a review of the information submitted and other information available regarding the two projects, including the mitigation plans for the projects. In the May 22nd request letters for the two projects, the explanation for the additional credit request was based on the fact that a more aggressive restoration approach was determined to be needed during the assessment and design stages of the two projects. The new approach for the streams on both projects was similar, in that it included such activities as adjusting the thalweg and centerline of the streams, installing a significant number of structures, incorporating bankfull benches, and adding bedform diversity. In the case of both Jacob's Ladder and Jacob's Landing, the IRT reviewed the projects in the field in August, 2011, and agreed to the mitigation approach described in the respective mitigation plans, which were finalized in September, 2012. As noted by Mr. Kulz' comments, the work that was done and is now the basis for the request for additional credit appears to be fairly consistent with what was proposed in the mitigation plan. In the case of Jacob's Ladder, the mitigation plan states that for Tributary T2-1 "Enhancement will include shaping the banks, creating a bankfull bench, creating a more stable and heterogeneous stream bed, and replanting the riparian buffer to achieve a mix of native tree species." For Jacob's Landing, the mitigation plan states that for Tributary T2A "This reach will be enhanced by shaping the banks to creating a bankfull bench, and installing grade control structures to gradually drop the bed elevation down. The reach will be stabilized by replanting the riparian buffer to achieve a mix of native tree species." Despite this fact, if the amount of functional uplift resulting from the work is sufficient to be credited at a 1:1 ratio, we do not want to penalize these projects for failing to identify an appropriate credit ratio up front in the mitigation plan. Another concern that arises from these requests is the way in which the changes to mitigation plan and credit yield were handled. As stated in the documentation submitted to the IRT, the need for a more aggressive approach was identified during the assessment and design stages of the mitigation process. This implies that the need to modify the approaches and associated credit structure for these tributaries was known well before construction yet not brought to the IRT's attention until the as -built stage of the project. Any modification to a project that results in a change to the mitigation approach substantial enough to warrant a different credit amount must be approved by the District prior to implementing that modification. In this case, the IRT was not notified of the change until the as -built stage of the project. Lastly, the information submitted in support of the requested change is not consistent. The final credit amounts presented during the IRT meeting do not match the credit amounts listed in the supporting information that was submitted after the meeting. Specifically, Jacob's Landing was shown to have 4,528 credits (SMUs) in the presentation and 4,524 credits in the supporting letter dated May 22, 2014. Similarly, Jacob's Ladder was shown to have 5,231 credits in the presentation and 5,203 credits in the supporting letter. In order to fully resolve this issue, please explain the discrepancy and identify the correct amount of credit to be generated by the two projects. To conclude, it is our intention to make sure that the amount of credit generated by mitigation projects, as expressed by the mitigation ratio, is supported by the level of uplift resulting from the work. In the case of these two projects, we agree that the uplift provided by the mitigation activities conducted in the two reaches in question may be credited at a 1:1 ratio. However, for future projects, changes such as this that result in a modification to the amount of credit must be approved in advance so that the District and IRT has the opportunity to comment and agree with the proposed approach. For all NCEEP projects that were instituted after the approval of the Instrument on July 28, 2010, such modifications should be approved in accordance with the streamlined review process outlined in Section 332.8(g)(2) of the Federal Mitigation Rule, unless the district engineer determines those changes are of a significant nature and must be processed through the normal procedures. In cases where such modifications are time -sensitive (e.g., construction is on-going), we will endeavor to expedite the review and approval to the extent allowable under the Rule. Thank you for working with us to address these issues. Please contact me if you have any questions about this letter, or if there is any additional information you need.
