The project was then transferred to WRP /EEP amidst the development of the construction plans. Proiect Setting and Background Summary The Kings Creek Stream Restoration Project is located on the mainstem of Kings Creek, a tributary to the French Broad River, on property owned by Brevard College, Transylvania County, North Carolina. It is located within HUC 06010105010050, the upper French Broad River watershed, which is listed as a Targeted Local Watershed (TLW) in the 2009 French Broad River Basin Restoration Priorities (RBRP) plan. Design development began in 2001 with NCSU and the CWMTF when a design document was developed. The project was subsequently acquired by EEP when construction plans were being developed by Buck Engineering and an option was obtained in April 2003. EEP implemented the design. Prior to restoration, land use immediately adjacent to the left bank of the creek (North) consisted of an old field and wetland. The latter was avoided as part of the design. A track and softball fields bordered the project site. Several private residences border the project on the right bank (South), some of which declined to offer a conservation easement in some areas. The total conservation easement consists of 6.1 acres, mostly contained within the Brevard College property. Historically, Kings Creek had been straightened and was incised due to historic channel buffer alterations. Active bank erosion along the project was significant in its extent and severity. The lack of riparian vegetation, incision, and widening impacted aquatic habitat and the project profile was devoid of pools. The reaches above the project on the college campus and in town are also heavily dominated by riffle bedform. The project is split into three reaches. The incised condition of the existing channel necessitated the restoration of the channel dimension, pattern, and profile along the fall of the valley as well as excavation of a new floodplain at the designed bankfull elevation. Reach 2 in its entirety and sections of reaches 1 and 3 include areas where the property owners on stream right declined to offer a conservation easement (see figure 1). No work was performed along the right bank in reach 2 or in the channel; however, excavation of the new floodplain continued along the left bank, maintaining floodplain connectivity between Reaches I and III. All other areas were subject to full restoration. The landowner on stream right for the lower 300 feet was approached once again in 2014 and has finally entered into an option that will allow for adequate buffer on stream right. This will be a contingency going into closeout. The site was treated for invasive plants 4 times in 2013 and is receiving an additional treatment in 2014. Species included Chinese privet, Mutliflora rose, Oriental bittersweet, Kudzu, Japanese honeysuckle, Japanese spirea, and Bamboo. Goals and Obiectives As stated in the May 2006 Kings Creek Mitigation Report, the specific objectives of the project are as follows: • Restore, to the extent possible, dimension, pattern, and profile along 2,119 linear feet of channel; • Improve floodplain functionality by matching floodplain elevation with bankfull stage, thereby increasing watershed attenuation and reducing peak flows; • Establish native floodplain vegetation, which will allow treatment of diffuse storm flow and nutrient uptake while establishing part of a wildlife corridor in the watershed; • Remove invasive exotic vegetation species from the stream corridor; • Improve the water quality in the Kings Creek watershed by reducing bank erosion, increasing nutrient storage and uptake, and increasing the dissolved oxygen of the system. Success Criteria • Dimension - Minor changes such as settling of the channel and banks, increase in vegetative density, decrease in width/depth ratio, and decrease in cross sectional area may occur and can be interpreted as a shift towards stability. The cross sections indicate stability with some narrowing observed and one of the pool cross sections decreased in depth earlier in the monitoring history, which since arrested. The site did experience some bank Page 2 of 22 stability. The cross sections indicate stability with some narrowing observed and one of the pool cross sections decreased in depth earlier in the monitoring history, which since arrested. The site did experience some bank erosion. EEP examined the site in 2014 and observed that approximately 200 feet ( -5% of the project bank footage) was noticeable and/or possibly active. Other areas which had developed in the past have since stabilized and the vegetation is very dense along the channel and the instream habitat is generally very good. The project has ready floodplain access and has overbanked many times during the monitoring period. Overall the project dimension is stable. • Pattern and Profile - Longitudinal profiles should show that bedform features remain stable, e.g., not aggrading or degrading. Short term aggradation/degradation may occur depending on peak annual discharge. Pattern, sinuosity, and pool /riffle sequence should not change over the monitoring period. The profile has remained stable and has significantly more diversity with significant pool habitat, which was nonexistent both above and within the project prior to construction. • Bed Material - D50 and D84 should increase (become coarser) in riffles and decrease (become finer) in pools. The pre- existing riffle substrate distributions indicated a pavement and subpavement D50 of 15 and 8 mm, respectively. The substrate distributions during monitoring were greater than or equal to these distributions with year 5 exhibiting general coarsening in the reach to coarse gravel. • Photo Reference Sites - For use in qualitatively assessing channel condition. Photos should indicate the absence of developing bars, scour, and bank erosion, while showing the maturation of woody vegetation on the project site. Some scour did develop, but the majority has arrested and the integration of vegetation, root wads and structures have made for excellent habitat. • Vegetation Survival Plots - Interim vegetative success will be based on 320 planted stems /acre at year three and final vegetative success will be based on 260 planted stems /acre. The sites vegetation plots indicate the success criteria were met. In general the sites vegetation is dense, of adequate size, and diverse with between 10 and 13 species per plot, 18 species site wide. Invasive plants are being controlled. Page 3 of 22 Table 3.

The project did experience some bank erosion over its history, the vast majority of which has arrested. Success criteria for channel substrate and vegetation were met. A total of 8 bankfall events were documented during the monitoring period with at least one occurring during each monitoring year with another observed during an site visit in early August. This likely represents a minimum. In summary, the Kings Creek Restoration Project is meeting success criteria and EEP recommends submitting the project for regulatory closure. Contingencies After prior unsuccessful attempts to obtain additional easement on stream right near the project terminus near Neely Rd., EEP was able to obtain an option for this area in 2014. The assets included in this report reflect the assumption that an easement for this section of adequate size will finally be secured. If not, the asset total will have to be reduced by an additional 201 feet. This area is currently forested and EEP will provide all easement documentation necessary for final closure upon securing this area Page 15 of 22 Pre Construction — 2004 -2005 2013 -2014 APPENDIX A: Watershed Planning Summary 208 — Kings Creek Watershed Characteristics Overview The Kings Creek project is located in the City of Brevard on Brevard College property in central Transylvania County, in the French Broad River Basin. It is located within HUC 06010105010050, the upper French Broad River watershed, which is listed as a Targeted Local Watershed (TLW) in the 2009 French Broad River Basin Restoration Priorities (RBRP) plan. Kings Creek flows into the French Broad River approximately 3,200 feet downstream of the project site. Neither Kings Creek nor the French Broad River downstream of the project site is on the 2012 North Carolina 303(d) list of impaired waters. There are 17 miles of High Quality Waters (HQWs) and Outstanding Resource Waters (ORWs) in this TLW and 11% of the watershed is in protected Conservation Areas. The 2009 RBRP identified 24 Natural Heritage Element Occurrences (occurrences of rare plants and animals or unique natural communities) within the TLW. The 64- square mile TLW is 18% agricultural, 65% forested (including wetland areas) and 17 percent developed. Major problems noted within this TLW (2009 RBRP) include limited riparian buffer vegetation, agricultural stressors (row crops and livestock), urban stormwater runoff, and areas of degraded in- stream habitat. Links to Watershed Goals and Objectives The Kings Creek project includes stream and buffer restoration and enhancement along approximately 1,800 linear feet of Kings Creek (pre- restoration length). The Kings Creek Mitigation Plan (Buck Engineering, 2006) and subsequent annual Monitoring Reports by Equinox Environmental note several project - specific stressors, including historic channel alteration/straightening, areas of active stream bank erosion and invasive non - native vegetation in the stream corridor. The project addresses these key stressors and contributes to the following watershed goals and objectives: - Improving floodplain functionality (restoring hydrologic connection between stream channel and floodplain through stream bank grading and in- stream structures); - Improved aquatic and riparian/terrestrial habitat through channel and buffer restoration; - Establishment of native vegetation along stream banks and floodplain; - Removal of invasive exotic vegetation from the riparian corridor; - Improvements to water quality in the Kings Creek watershed through reduced nutrient and sediment inputs (physical filtration of sediments and chemical transformation of nutrients in the buffer zone). The project - specific actions noted above and the additional (non -EEP) projects noted below all contribute to improvements in water quality and aquatic habitat within the upper French Broad TLW, including HQW and ORW classified reaches. Page 17 of 22 APPENDIX A: Watershed Planning Summary Watershed Summary There are no other EEP mitigation projects within this HU. However, there are 36 documented agricultural BMP sites in the watershed (NC Division of Soil and Water Conservation, 2014). These comprise a wide variety of projects /practices, including agricultural waste application equipment, stabilization of animal heavy use areas, pasture renovations, stream bank and buffer restoration/enhancement, micro - irrigation, alternate watering sources (tanks, troughs, wells), livestock exclusion fencing, urban cisterns, and critical area plantings (vegetative stabilization of eroded farm areas). Also, a NC DWR 319 grant in 2005 was used to develop a watershed education and outreach program for Transylvania County, including the upper French Broad River watershed. In addition, there are three NC Clean Water Management Trust Fund (CWMTF) projects in the watershed, including riparian buffers acquisition by the City of Brevard and the Carolina Mountain Lands Conservancy. e 9 � S' k8 tel Forts LarR�4 +r ' °e.:.
