(Baker) restored, enhanced or preserved 5,110 linear feet (LF) of perennial stream channel along Logan Creek and eight unnamed tributaries (UT1,UT2, UT3, UT4, UT5, UT6, UT7 and UT8) in Jackson County, NC (Appendix A). The nearest town, Cashiers, is approximately five miles west of the Logan Creek Project site. The site lies in the Savannah River Basin within the Targeted Local Watershed 03060101-010020 (Horsepasture River) and within the North Carolina Division of Water Resources (NCDWR) sub -basin formerly known as 03-06-01-01 (Keowee River Subbasin). The Horsepasture River is a National Wild and Scenic River and a state -designated Natural and Scenic River. The project involved the restoration, enhancement, and preservation of a stable channel and a Montane Alluvial/Montane Oak -Hickory Forest system (NCWAM 2010, Schafale and Weakley 1990) from impairments within the project area due to past agricultural conversion including orchard development, trout hatchery development, mink farming and more recently single-family home development. The project goals directly address stressors identified in the Savannah River Basin Restoration Priority Plan (RBRP) (DMS 2001 and updated 2008) such as habitat degradation, inadequate riparian buffer cover, channel modification, and excess nutrient and sediment loading. The primary restoration goals, as outlined in the approved mitigation plan, are described below: • Create geomorphically stable stream channels within the Logan Creek project site. • Protect stable areas as well as mature trees and other desirable vegetation. • Improve water quality within the Logan Creek project area through reduction of bank erosion, improved nutrient and sediment removal, and stabilization of streambanks. • Improve aquatic and terrestrial habitat. To accomplish these goals, we recommend the following actions: • Restore the existing eroding or over -wide stream reaches by creating a stable channel that has access to its floodplain. • Improve in -stream habitat by providing a more diverse bedform with riffles and pools, creating deeper pools, providing woody debris for habitat, moving sand deposits through the reach and reducing bank erosion. • Establish native stream bank and floodplain vegetation to increase storm water runoff filtering capacity, improve bank stability, provide shading to decrease water temperature, provide cover, improve wildlife habitat and protect this area with a permanent conservation easement. • Improve terrestrial habitat by increasing the density of tree species that root deeply, by thinning the thick stands of rhododendron within the easement area and planting a more diverse native plant community. During Monitoring Year 2 (MY2), our monitoring activities indicated that the planted acreage was functioning well with most banks, benches and floodplain areas developing a diverse herbaceous community and having good growth of planted trees. The access areas used during construction were particularly difficult to stabilize but after hydro -seeding they are now well vegetated. The Vegetative Problem Area noted in the MY report developed a good stand of herbaceous vegetation, along with the planted trees and is no longer a problem area. Our discussions with the landowner concerning mowing encroachments along the easement line (MY I: EA -1 & EA -2) by maintenance staff and their encroachment by installing the outlet of a drainpipe within the easement were addressed and were not an issue this year. There were no Vegetative Problem Areas identified during 2016. There was one Encroachment Area (EA -1) noted in 2016. A new maintenance staff person had the MICHAEL BAKER ENGINEERING, INC. 3 LOGAN CREEK STREAM RESTORATION PROJECT, DMS PROJECT NUMBER - 92515 DECEMBER 2016, MONITORING YEAR 2 OF 5 nature trail mowed, which is allowed under the easement; however, a wider area was mowed than we verbally agreed should be maintained. The width was 10-12 feet wide, while we had agreed to a width that is 4-6 feet wide, which is approximately the width of the previously existing nature trail. We discussed this with one of the Lonesome Valley staff, they agreed to address this issue with the trail maintenance staff, and to be sure they know the proper width for future maintenance. The three channel problem areas noted in the MY1 report stabilized naturally. During December 2015 and January 2016, two greater than bankfull flows occurred. The crest gauge shows a depth on the floodplain at the gauge location of 25.75 inches and photos of wrack lines showed flooding on the floodplain more than 50 feet from the top of the stream bank. This flooding caused five small areas of bank erosion or instability along the project reach. We have shown photos of these areas from the summer of 2016 (Appendix D, Table 14) which indicate that these sites are naturally stabilizing. All of these areas are less than ten feet by five feet in area and will be further stabilized by sloping the area, seeding, mulching, matting and installing live stakes during the winter of 2017. As noted in the Baseline report, we installed eight (8) vegetation monitoring plots at this site, with seven (7) being installed along the restoration reach (Logan Creek, Reach 1) and one (1) being installed along the enhancement reach (Logan Creek, Reach 2). The location of these vegetation monitoring plots can be seen on Figures 2A -C. The average density of total planted stems following the MY2 growing season is 728 stems per acre (SPA). Volunteer stems were much more common this year with volunteers being observed in six out of the eight plots and the average density of volunteer trees was 516 SPA. Stream geomorphological stability and performance during MY2 was assessed by surveying thirteen (13) cross- sections (8 on Logan Creek, 2 on UT3, 2 on UT6 and 1 on UT8) and a profile of Logan Creek, UT3, UT6 and UT8, evaluating the bed particle size with 3 riffle pebble counts and by observation and replicating channel location photographs. An additional cross-section was added on UT8 during MY2 surveying so that we have cross-sections on all restored tributaries. Cross-sections of all the channels indicated that there was very little change in the cross-sections during MY2. The particle size observed in MY2 pebble counts has decreased slightly which may be attributed to the drought conditions that this area experienced during MY2. No observed changes indicate any instability. The Visual Morphological Stability Assessment indicates that the Site is stable and performing well. All but one structure (CPA -2), are functioning as designed during MY2. CPA -2 is a log that is part of the rock-and-roll structure and the fabric was torn during flooding (Table 14 in e -file data). This will be repaired prior to the 2017 growing season. Channel morphology is responding as designed and meeting project goals. Lonesome Valley installed a trail crossing near the top of the project site. This crossing replaces a crossing that existed prior to this project. This addition required a reduction of three feet from the total restoration footage, restoration SMUs and a slight increase in preservation footage and SMUs. These modifications are reflected in Table 1. Summary information/data related to the Site 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 available on the NCDMS website. All raw data supporting the tables and figures in the appendices are available from NCDMS upon request. 2.0 METHODOLOGY The monitoring plan for the Site includes criteria to evaluate the success of the stream and vegetation components of the project. The methodology and report template used to evaluate these components adheres to the NCDMS monitoring guidance document dated December 1, 2009 and other mitigation guidance (NCEEP 2009 and USACE 2003), which will continue to serve as the template for subsequent monitoring years. The MICHAEL BAKER ENGINEERING, INC. LOGAN CREEK STREAM RESTORATION PROJECT, DMS PROJECT NUMBER - 92515 DECEMBER 2016, MONITORING YEAR 2 OF 5 specific locations of monitoring features: vegetation plots, permanent cross-sections and profiles, and the crest gauge location, are shown on the Current Conditions Plan View (CCPV) sheets found in Appendix A. Vegetation monitoring plots, pebble counts and site photo points were monitored in September 2016. Site surveys for channel cross-sections, photos and profiles were conducted in October 2016. 2.1 Vegetation Assessment In order to determine if success criteria are achieved, vegetation monitoring quadrants (veg plots) were installed and are monitored in accordance with the CVS-NCDMS Protocol for Recording Vegetation, Version 4.1 (CVS 2007 and Lee, Peet, Roberts and Wentworth 2007). The vegetation monitoring plots are a minimum of two percent of the planted portion of the Site with eight plots established randomly within the planted riparian buffer, per CVS Monitoring Level 2. No veg plots were established within the undisturbed forested areas along the northern part of the project or within the undisturbed forested areas along Reach 11 of Logan Creek and UT5. A small area was disturbed within this enhancement reach so that structures and channel repairs could be made during construction. Veg Plot 1 is located in this area where bare root trees and seed were planted. The sizes of individual quadrants are 100 square meters for woody (tree) species and 1 square meter for herbaceous vegetation. Herbaceous vegetation quadrants were established in one corner of the larger woody vegetation plots and monitored by comparative photographs taken each year. Trees surviving within vegetation monitoring plots were visually accessed during year two monitoring. We found that all vegetation was in good condition. All plots indicated that most trees were growing and in good to excellent condition and herbaceous vegetation was well established and growing well. The average density of total planted stems following the MY2 growing season is 728 SPA (n=8) with a range from 445 SPA to 971 SPA. The average density of volunteer trees was 516 SPA and the density ranged from 0 to 1,133 SPA. The overall SPA including both planted and volunteer stems was 1,244. With an average planted density of 728 stems per acre, the Site is on track to meet the minimum interim success criteria of 320 stems per acre by the end of MY3, and the final success criteria of 260 stems per acre by the end of MY5. There were few invasive species observed at this site during Year 2. Observation during monitoring activities indicated that there were only a few scattered individual small plants of the invasive species, Multiflora rose. Larger individual plants of this species were treated during construction and killed but new growth appears to be occurring from the existing seed bank. We will continue to monitor for additional plants growing and will treat these as needed. No areas of concern regarding the existing vegetation was observed along Logan Creek or any of the tributaries. Year 2 vegetation assessment information is provided in Appendix C. 2.2 Stream Assessment The approach for the Logan Creek Site includes the restoration of channels to a stable morphology that allows for the transport of water and sediment through the Site and allows stream flows larger than bankfull flows to spread onto the floodplain. Stream monitoring efforts focus on visual observations, a crest gauge to document bankfull flooding events, surveying established stream cross-sections and channel profiles to assess channel stability and pebble counts to assess if proper sediment transport is taking place. Stream survey data was collected to a minimum of Class C Vertical and Class A Horizontal Accuracy using Leica TS06 Total Station and was georeferenced to the NAD83 State Plane Coordinate System, FIPS3200 in US Survey Feet, which was derived from the As -built Survey. This survey system collects point data with an accuracy of less than one tenth of a foot. 2.2.1 Morphologic Parameters and Channel Stability Cross-sections were classified using the Rosgen Stream Classification System (Rosgen 1994) and all cross-sections were evaluated to determine if they meet design expectations. Cross-sections were also MICHAEL BAKER ENGINEERING, INC. LOGAN CREEK STREAM RESTORATION PROJECT, DMS PROJECT NUMBER - 92515 DECEMBER 2016, MONITORING YEAR 2 OF 5 compared to the baseline and MY1 cross-section plots to evaluate changes in the cross sections. Morphological survey data is presented in Appendix D. A longitudinal profile was surveyed for the entire length of Logan Creek, UT3 and UT6, and UT8 to document changes during year 2 of monitoring. The survey was tied to a permanent benchmark and measurements included thalweg, water surface (where flow was present), and top of low bank. Each of these measurements was taken at the head of each feature (e.g., riffle, pool) and at the maximum pool depth. Stream geomorphological stability and performance during MY2 was assessed by surveying thirteen (13) cross-sections (8 on Logan Creek, 2 on UT3, 2 on UT6 and 1 on UT8) and a profile of these channels as described above. The bed particle size was evaluated with three riffle pebble counts and by observation and replicating channel location photographs. An additional riffle cross-section and profile was added on UT8 during MY2 surveying, so that we have this information on all the restored tributaries. Cross-sections and profiles of all the channels indicated that there was very little change in the channel during MY2. Some pools became shallower during the year, however, this site like most of western North Carolina, experienced severe to extreme drought that began in March and is continuing at the time of this report. The low flow within the channel has caused sand to accumulate within the pools. Once the drought is over and normal flows return, the pools should return to their design depth through natural scour. The Visual Morphological Stability Assessment indicates that the Site is stable and performing at 98 to 100 percent for all parameters. One structure (on Logan Creek Reach 1) was piping during MY2 (CPA -2). This structure had fabric that was sealing the upstream side of the log, torn during flooding. This issue will be repaired prior to the next growing season (Table 14 in e -file data). Overall, channel morphology is responding as designed and meeting project goals. Pebble count data for MY2 indicates a shift back to smaller particle sizes at all of the riffles sampled. This is the opposite of what was observed in MYL The channel had a mean D50 of 16.5 mm during baseline sampling and 36.9 mm during MY1 but this changed to an average of 22.2 mm in MY2. This represents a change from very coarse gravel in MY1 to coarse gravel this year. Again, this may be related to the very low flows during the drought that has continued for most of 2016 and the streambed will likely coarsen again when flows become more normal. 2.2.2 Hydrology A crest gauge was installed on the floodplain at the bankfull elevation along the right top of bank on Logan Creek at approximate Station 30+00. There was at least one major bankfull event recorded on the crest gauge during MY2. The crest gauge indicated a water depth on the floodplain of 25.75 inches during this flooding. Stream flow data from a recording station at Lake Toxaway indicates that these storms may have occurred on December 29, 2015 or February 3, 2016. There were also physical indications of this flooding, such as large debris and wrack lines that indicated a flooding situation that extended well beyond the top of bank (see photos with Table 11). Crest gauge readings are presented in Appendix D. 2.2.3 Photographic Documentation Reference transects were photographed at each permanent cross-section. A survey tape is normally centered in the photograph when the tape is used to identify the transect. The water line was located in the lower area of the frame, and as much of the bank as possible included in each photograph. Photographs were taken at specific photo points established along each channel during year 2 monitoring. Photographs from these points are replicated each year and used to document changes along the channel. Points were selected to include grade control structures as well as other structural components installed during construction. Annual photographs from the established photo points are shown in Appendix D. MICHAEL BAKER ENGINEERING, INC. LOGAN CREEK STREAM RESTORATION PROJECT, DMS PROJECT NUMBER - 92515 DECEMBER 2016, MONITORING YEAR 2 OF 5 2.2.4 Project Problem Areas Project problem areas fall into three types: Vegetation Problem Areas (VPA), Encroachment Areas (EA), and Channel Problem Areas (CPA). All observed problem areas are shown on the CCPV maps. There were no VPAs identified during MY2. Vegetation was well established across the entire project site. During winter of 2015/2016, two greater than bankfull flows occurred as discussed above and this resulted in five channel problem areas (CPA 1-6). This flooding caused five small areas of bank erosion or instability along the project reach. In the photos included with Table 14, we have shown photos of each CPA, with photos of some of these sites from summer 2016, which indicates that the these sites are naturally stabilizing. All of these areas are less than ten feet by five feet in area and will be further stabilized by sloping the area, seeding, mulching, matting and installing live stakes during the winter of 2017. A nature trail exists along the stream beginning at the lower end of Reach 1 and continuing upstream to the trout pond. This trail falls within the easement in many locations but also passes out of the easement in others. This was a pre-existing nature trail and the right to maintain it is allowed in the conservation easement. There was one Encroachment Area (EA -1) noted in 2016 along the nature trail, in the area of stations 23+00 to 28+00. A new maintenance staff person had the nature trail mowed; however, a wider area was mowed than we verbally agreed should be maintained. The width was 10- 12 feet wide, while we had agreed to a width of 4-6 feet wide, which approximates the width of the previously existing nature trail. We discussed this with staff at Lonesome Valley and they agreed to address this issue with the trail maintenance staff, and to be sure they know the proper width for future maintenance. All issues discussed above reference the CCPV mapping and the Stream Problem Area table included in the e -File data with associated photos. 3.0 REFERENCES Carolina Vegetation Survey (CVS) and NC Ecosystem Enhancement Program (NCEEP). 2007.
