The project is located south of Banner Elk on the west side of NC 184 (Tynecastle Road), in the mountasn ecoregion of North Carolina (Figure 1}. The property at BannerLowes is ' composed of a total of 29.3 acres bordering Tynecastle Road. Tynecastle Road is the major thoroughfare into the Town of Banner Elk and the primary commercial corridor. This property has 720 feet of road frontage on Tynecastle Road. Primary access to the tract is through the ' Lowes access drive from Tynecastle Road. Secondary access is over a private road (Glove Factory Lane) adjacent to the old Glove Factory land (south} and a private road (Stonebridge Lane) adjacent to a Car Wash (north}. Land use in the project vicinity is commercial along Tynecastle Road with residential homes set back from the road. The property was used for a residential home, barn and agricultural pasture prior to construction of the commercial buildings. 1 C' 1 1 The project is located within the Elk River watershed of the Watauga River Basin. The site lies in US Geological Survey (USGS) Cataloging Unit 06010103 and North Carolina Division of Water Quality (NCDWQ) sub-basin 44-02-01 of the Watauga River Basin. The mitigation project involves three streams and two wetlands on the property. There are two unnamed tributaries (UTA &UTB), with UTA flowing into the Elk River on the southeast side of the property. UTB flows into the Elk river at a point downstream of the property. The Elk River borders the property on the east side. The drainage areas involved include the Elk River at 2.95 square miles, the UTA at 4.04 square miles, and the UTB at 0.1 square miles. The Elk River flows parallel to Tynecastle Road and bisects the property. The Elk River was approximately six feet wide and six inches deep with a cobble, gravel, and sand substrate. The river experiences impacts from beaver activity and floods (March 2003 and September 2044). These impacts had resulted in bank and channel degradation of the Elk River on the property. Preconstruction conditions can be seen in the photographs in Appendix A. Table 1. Summary of As-built Lengths and Restoration Approaches.

Location of BannerLowes Stream and Wetland Restoration Site ~`~, ~~ 0 80160 320 480 640 `` ~' Feet i~ ' For the restoration project, the lower portion of the Elk River (3871f) was stabilized and the profile and dimension restored in the stretch (Figure 2). UTA was relocated to the south side of ' the property and restored for a length of 5361£ Another UT joins with UTA near the head of the stream, but is not included in the mitigation project. UTA is a perennial stream and was channelized prior to the project. See photographs of the stream before the project was constructed in Appendix A. UTB had been channelized and all riparian vegetation removed during the agricultural use of the property. UTB was an intermittent stream upstream of the property and became a perennial stream downstream at the confluence with two tributaries draining the springs west of the property. UTB was relocated and restored to a length of 1,089 lf. UTB had been channeiizeci through the pasture, flowing northward into an old pond bed ' (Appendix A). The restoration project included two wetlands located adjacent to the Elk River on the east side ' of the river. The project restored x acres of the downstream wetland. The upstream wetland above the bridge was located between the stormwater wetland BMP and the Elk River. It was restored to x acres m size. The design for the BannerLowe project involved the restoration of channel dimension, pattern, and profile on the Elk River and two of its unnamed tributaries (UTA and UTB). After ' construction was complete, 2,012 feet of stream had been restored on the site and x acres of wetland. This Annual Report details the results of the monitoring efforts performed during 2006 (Year 1) at the BannerLowe Site. i~ i~ 1 i Project History February 2005 Site Mitigation Plan Completed May 2005 Construction Begins on UTA and UTB July 2005 Completed Construction of UTA and UTB; preliminary live stakes, matting and seeding October 2005 Completed Construction of Elk River; vandalism of planted trees and shrubs on UTA and UTB noted December 2005 Trees and shrubs planted on streams and river January 2006 UTA repaired Apri12006 Live stake planting on streams and river; ATV damage to buffer on UTA noted May 2006 Completed Construction of Wetland Cells; Repaired structure on UTB June 2006 Wetland areas seeded and live stakes; buffers reseeded and planted September 2006 Replanted vandalized or damaged/dead trees and shrubs November-December 2006 Additional replacement trees planted in buffers METHODS April-May 2007 Live stakes planted on wetland berm along river June 2007 lst Annual Monitoring Report Longitudinal and cross section reference sites were photographed immediately after construction and will be documented for at least five years following construction. Photographs will be taken at each of the vegetation plots during each growing season for at least five years following construction. Two (2) permanent cross-sections will be installed per 1,400 linear feet of stream restoration work, with one (1) located at a riffle cross-section and one (1) located at a pool cross- section. There were two cross sections installed on each restored stream segment. A longitudinal profile will be completed once during the first year after construction and then every two years (for a total of three times over the five year monitoring period). Measurements will include thalweg, water surface, inner berm, bankfull, and top of low bank. Bank erosion measurements will be made at each permanent cross section. A bank erodibility hazard index (BERT) score will also be made at each cross section. Pebble counts will be ~ ` conducted at each permanent cross section (100 counts per cross section) and reach-wide over twenty bankfull widths (100 counts total). Pebble counts will be conducted one year after construction and at a two-year interval thereafter at the time the longitudinal field surveys are performed. Vegetative monitoring plots were established on each of the stream restoration stretches. There were two 25'x 50' plots each established on UTA, UTB and the Elk River. Trees and shrubs are flagged and counted each year and survival will be determined based on initial plantings. Within these monitoring plots, herbaceous vegetation will be monitored using a one meter plot for determining density and diversity of herbaceous vegetation. Live stakes are monitored with one plot 50' long on both sides of the streams adjacent to the vegetative monitoring plots, with all live stakes counted and tracked to determine survival. ' Wetlands will be monitored for success using hydrology determinations through groundwater wells, crest gage, stream gage and rainfall data, wetland rating scores, vegetative stem counts, herbaceous density and diversity, hydrophytic vegetation, and photographs of the two wetland ' areas through the monitoring period. These conditions will be monitored for five years or until success criteria have been met. ' RESULTS -Listed Chronologically from Pre Construction Pre Construction Conditions 2004 ' Pre-construction observations in April 2004 of the streams UTA and UTB showed impacts from the agricultural use of the land surrounding the two streams. Photographs of the pre-construction ' conditions can be found in Appendix A. UTA had very Little buffer and was not protected from livestock access. UTB had some areas of natural vegetation and buffer, especially near the wetland areas on the west side of the project. Most of UTB was heavily impacted from clearing ' and livestock access, with drastic changes in pattern and dimension as can be seen in the photographs in Appendix A. The Elk River through the project had areas of bank erosion, dimension impacts from beaver dams, and clearing of the buffer through mast of the length ' within the project boundaries. The wetlands on the project had been impacted historically through fill and livestock access to the area. All of the valley wetlands and the Elk River were heavily impacted through three consecutive floods in September 2004. The Elk River shifted its channel to the west and much of the wetlands closest to the river were f lied with sand and rock debris from the floods. The ' Elk River was relocated back into its original channel in October to prevent the channel erosion and sediment load from cutting a new channel. The wetland areas adjacent to the river were heavily impacted from sand and rack deposits and were greatly reduced in size and function. Photographs of these conditions can be seen in Appendix A. Restoration of the wetlands and the connection with the Elk River through the mitigation plan would restore these wetland areas. 1 1 Post C'onstruetion 2005-2006 ' Vegetation Monitoring Longitudinal Profile and Cross Section Bank Erosion estimates and BEHI ' Pebble Count Wetland Restoration ' Plans showing as built conditions for the three streams and the two wetlands are included in Appendix B. The active project construction extended over a long period of time with more than a year in construction and planting activities for the project. As can be seen on the timetable of ' the project history, the stream restoration projects were completed at two different times in 2005. The wetlands were not completed until May of 2006. Vegetation planting efforts were spread out throughout and are continuing into 2007, due to seasonal planting requirements. There were ' multiple impacts to the streams and wetlands from adjacent construction activities, including stormwater BMP construction, sediment and erosion control structures, utility installations, and general construction impacts. Vandalism had been noted in 2005 and is still being observed through current field surveys. All of these impacts on the projects will be discussed as it impacted the individual monitoring components and how the impacts were repaired. Lowes opened for business in early July 2006, ending most landscaping and associated construction ' activities. No excessive rainfall events or floods occurred during 2005 or 2006. Rain events are ' documented under the Wetland Restoration monitoring for the site. There were high stream level events but no bankfull events in 2005 or 2006 as recorded by the crest gage. More discussion of the precipitation and stream levels will be covered under the stream longitudinal ' profile and the wetland restoration sections of this report. Vegetation Monitoring ' STREAMS Plantings on the three streams began as early as July 2005 and are still continuing into 2007. 1 There was a partial livestake planting on UTA and UTB in July 2005 along with native grass seeding to provide an initial headstart for bank stabilization. Elk River was planted with native seeds and Iivestakes in October of 2005. All three streams were planted with trees in December ' 2005 and with the rest of the livestakes in March/April of 2006. Some areas on the streams and the Elk River could not be planted, due to continuing site construction, sediment control fencing, and other limiting factors. In December 2005, a sewer line crossing disturbed a portion of UTB t and a construction vehicle became stuck in UTA, requiring repairs on both those streams. Several trees that had been planted along along the streams and river were observed run over, pushed over or pulled up. Constriction on utility lines had impacted all plantings near the lower ' section of UTB on the west side. UTA had lost all of its tree plantings on the south side of the stream in the area from the berm to the side unnamed tributary, probably due to the ATV that was observed in May 2006 using the area as a dnving track. The area was posted with signs and replanted m the summer of 2006. 6 Initial vegetation plantings were surveyed during July 2006 for live stakes, tree plantings and herbaceous cover in the monitoring plots (See photographs in Appendix B). WETLANDS Wetlands were completed in May 2006 and seeds and livestakes were planted where final construction grade was in place. The wetland areas immediately showed signs of hydrology, hydric soil development and immediate establishment of hydrophytic vegetation with good growth as can be seen in the Photos in Appendix B. Both wetlands could not be planted along the Elk River due to construction activities and the upper wetland was limited in planting on the stormwater wetland side until after June 2006. The joint monitoring plots for the lower wetland ' and the Elk River were established and initial stem counts were made. RESULTS ' Vegetative monitoring plot data for the streams and wetlands showed some of the above impacts during the July survey, but not all of the impacts. The tables of the results can be seen in Appendix B. The data shown are the initial planting data because none of the plots have been ' through a full growing season except for the live stakes on UTA and UTB. Only six monitoring plots out of eleven were up to design planting numbers in 2006. The other five plots were still under impacts from construction activities. The number of tree and shrub stems per acre ranged ' from 67 to 633 stemslacre. Livestake plots ranged from 1200 to 1633 stemslacre on the streams. The wetlands monitoring plots were only partially planted in 2006 and ranged from no livestakes in one plot to 600 stems/acre in the second plot. Herbaceous plots were established on all streams ' and wetlands in 2006 and will be surveyed in 2007 after a full year of unimpacted growth. Preliminary surveys show that the herbaceous plots are experiencing good growth and cover in the meter plot. New plantings and replantings of trees, shrubs and livestakes are planned for the ' winter of 2006-2007 to insure the initial counts met design criteria and will be reported in the 2007 monitoring report. ' Longitudinal Profile and Cross Section The total length of stream channel restored on the three streams on the site was 2012 feet. This entire length was inspected during Year 1 of the monitoring period (2006) to assess stream ' performance. Two cross sections and one longitudinal profile on each stream were surveyed and plotted in October 2006 and are shown in Appendix B. A third cross section on Stream B (Cross Section #1) was located in the intermittent flow section and has had no flows except for rain runoff. This cross section will be dropped and the two downstream cross sections will be used. Longitudinal profile graphs for each stream are shown in Figures 3-5. Based on the data ' collected, all riffles, pools, and other constructed features along the restored channel are stable and functioning as designed. The lack of significant problem areas along the length of the restored channel after the occurrence of at least one nver flow larger than bankfull discharge further supports functionality of the design. It is expected that stability and in-stream habitat of the system will only improve in the coming years as permanent vegetation becomes more established.

Longitudinal Profile UTB, BannerLowe Mitigation Project, October 2006, Banner Elk, NC. Photographs of each stream profile and cross section are included in the Appendix B of this report. Bank Erosion estimates and BEHI Bank erosion estimates were not performed in 2006, but the cross section surveys show no change from the as-built conditions. Erosion pins will be installed in 2007 and monitored for the remainder of the monitoring period. BEHI observations for UTA were low to very low as the vegetation is very well established, the channel is connected to its floodplain, and the slope is low. There is one area of higher BEHI where the second UT confluence enters UTA. UTB has more disturbed channel where the flood event in late 2005 washed out all channel vegetation down to rock and bedrock, but the stream banks were recovering and were well covered with vegetation. UTB BEHI ranges from Low to Moderate with some areas showing a High rating. The Elk River has vegetation growing along its stream banks, but has been slow to completely cover the banks as the majority of the bank materials were large cobble and even some boulders. This helps to maintain the stability of the stream banks even without the vegetation growth. The Elk River BEHI ranges from Very Low to Moderate, depending on the amount of rocks present in the bank. Pebble Count Pebble counts at each permanent cross section and reach-wide over twenty bankfull widths were performed on the three restored streams and the data is shown in Appendix B. Pebble counts for the Elk River show a very coarse gravel substrate for the river. UTA and UTB have a medium 9 ' gravel substrate. UTB is receiving some sediment from the upstream channel construction which has not had any water flow other than rain runoff since construction began on the site. The ' intermittent channel has become ephemeral until the confluence with the wetland channels. Downstream of the wetland flow the UTB is perennial. ' Wetland Restoration Two wetland areas adjacent to the Elk River on the east side were restored. This construction was completed in June 2006 and the wetlands have not experienced a full year after construction yet. Preliminary groundwater data, stream height, and crest levels from August 2006 to February 2007 are shown in Appendix B. Initial data indicates that when the stream levels rise, the groundwater gages in the two wetlands also respond with a rise in water level. Soil observations indicate that hydric soils are already developing in both wetland areas. Hydric vegetation has ' covered both wetlands except in the deeper water areas. The upper wetland has experienced ponding on the Lower end and adjustments are being made to lower the standing water level. Final adjustments will be made dunng the growing season of 2007 in order to maintain ' hydrology of the wetland. All indications show that the two created wetlands are functioning as effective wetlands and maintaining the hydrology, vegetation and hydric soil conditions of a npanan wetland connected to the ad}scent Elk River. FUTURE SAMPLING Annual sampling will be performed at the BannerLowes Project site in 2007, 2008, 2009 and 2010. 1 10 1 1 Appendix A Pre-Construction Photographs 11 .~, ~= - ._ ~, . _ ~ ~ ~., ~~ ,,"'° ~. 1 R ~ ~, \ ~ R- req.. - > 4$,``~ ., y~ r `° Elk River looking downstream, behind Elk River looking downstream on Bannerlowe Great Train Factory, Bannerlowe Project, April 15, 2004, Avery County, NC.
