The site contains land in both Rutherford County and McDowell County. Latitude and longitude for the site are 35.521163 N and 82.007344 W, respectively. The site is located within the Sugar Hill and Glenwood USGS Topo Quads. To access the site from Asheville, take I-40 East to Exit 85 - Highway 221. Turn right at the top of the exit ramp and continue on Highway 221 South for approximately 9 miles. Turn right onto Thermal City Road. Continue on Thermal City Road approximately 1 mile to a "fork". Take the right "fork" and continue on Thermal City Road for another mile. The entrance to the property will be on the right. Devin McCarthy Land Development, LLC proposes to develop the Queens Gap residential development on approximately 3,500 acres. This includes the construction of an 18-hole golf course and practice area. Devin McCarthy Land Development, LLC is proposing the following enhancement plan for the entire area. Some enhancement will be used as mitigation but the overall goal of the enhancement activities on site is to provide a structurally stable hydrologic system and improve water quality throughout the golf course. Existing Site Conditions Queens Gap is forested, except where golf holes have been cleared and under brushed. There is an extensive existing logging road network throughout the site. A Mixed Mesic Forest type dominants the landscape. This forest type occupies rich, acidic, moist, well-drained sites and contains the most diverse plant communities in the Southeast. The dominant tree species are American beech (Fagus grandifolia) and oaks, specifically northern red oak (Quercus rubra) and white oak (Quercus alba). Other tree species that are abundantly common in these forests include: ash, hickory, Fraser's magnolia, red maple, tulip poplar, hemlock, and buckeye. All are present within Queens Gap. This forest type also has a very diverse shrub and herbaceous layer. Species at this site include heart's-a-bustin', mountain laurel, pepperbush, ironwood, rhododendron, spice bush, wild hydrangea, black cohosh, bloodroot, doll's eye, false soloman's seal, galax, jewelweed, may apple, Christmas fern, liverleaf, and alumroot. All unnamed tributaries within the development flow into Harris Creek. Harris Creek is a tributary to Cathey's Creek, which flows into the Second Broad River. The Second Broad River flows to the Broad River, which is a navigable water. UT1, UT2, and UT3 make up the largest unnamed tributary network within the golf course project boundary. These tributaries are relatively small and flow to the east of Harris Creek. UT4 and UT5 flow north of Harris Creek. They are relatively small, good quality streams. UT5 parallels Harris Creek for approximately 750 linear feet before its confluence with UT4. Harris Creek is the only named tributary flowing through the golf course project boundary. It is a moderate size stream of overall good quality. There are several bank failures along Harris Creek; the most notable located just north of the southern-most boundary. This failure is approximately 150 feet long with a sheer right bank approximately 40 feet high. North of the large bank failure and on the west side of Harris Creek is a linear wetland feature. This feature resembles an old ditch and drains directly into Harris Creek. UT6 is the western-most tributary within the property boundary. UT6 is of poor quality and highly degraded. Degradation and excess sediment has been attributed to an upstream impoundment and dam. The existing pond is approximately 2 acres. It is devoid of most vegetation along its banks. There is one old cabin immediately below the dam and adjacent to the stream. Degradation of the tributary can also be attributed to poor upkeep and waste elimination practices at the cabin. There is a large wetland immediately upstream of the impoundment, presumably the result of road construction and a clogged intake pipe. This wetland has naturalized and maintains shallowly ponded water. There is another disjunct linear wetland segment section north of the ponded wetland. Precipitation According to the PRISM maps (see Attachment A) maintained by the Natural Resources Conservation Service, this area of Rutherford County receives approximately 50 to 56 inches of precipitation per year. Excess water that falls as precipitation must leave the site as ground water flow, runoff, channelized surface flow, or deep seepage. Soils The project site is located on the border of the Piedmont and Mountain physiographic region of North Carolina and is located within the Pacolet-Cecil and Evard-Cowee-Fannin soil associations. Soil series present on site include Appling, Dogue, Evard-Cowee Complex, Pacolet, Pacolet-Saw complex, and Rion. The Appling series consists of very deep, well-drained, moderately permeable soils on ridges and side slopes of the Piedmont uplands. They are deep to saprolite and very deep to bedrock. They formed in residuum weathered from felsic igneous and metamorphic rocks of the Piedmont uplands. Slopes range from 0 to 25 percent. Near the type location, mean annual precipitation is 45 inches and mean annual temperature is 60 degrees F. The Cowee series consists of moderately deep, well-drained, moderately permeable soils on ridges and side slopes of the Blue Ridge. They formed in residuum affected by soil creep in the upper part, and weathered from felsic to mafic, igneous and high-grade metamorphic rocks. Slope ranges from 2 to 95 percent. Near the type location, mean annual temperature is about 56 degrees F., and mean annual precipitation is about 49 inches. The Dogue series consists of very deep, moderately well drained soils located in low streams in the piedmont and on the coastal plain. Near the type location, mean annual precipitation is 38-54 inches and mean annual temperature is 57-66 degrees F. The Evard series consists of very deep, well-drained, moderately permeable soils on ridges and side slopes of the Blue Ridge. They formed in residuum affected by soil creep in the upper part and weathered from felsic to mafic, igneous and high-grade metamorphic rocks. Slopes range from 2 to 95 percent. The Pacolet series consists of very deep, well-drained, moderately permeable soils that formed in residuum weathered mostly from felsic igneous and metamorphic rocks of the Piedmont uplands. Slopes commonly are 15 to 25 percent but range from 2 to 60 percent. The Rion series consists of very deep, well-drained, moderately permeable soils that formed in material mostly weathered from acid crystalline rocks of the Piedmont Uplands. Slopes commonly are 15 to 25 percent but range from 2 to 60 percent. The Saw Series consists of moderately deep, well-drained soils on ridges and side slopes of the Piedmont uplands. They formed in residuum weathered from felsic igneous rocks such as porphyritic granite. Slopes range from 2 to 45 percent. Near the type location, mean annual air temperature is 61 degrees F., and mean annual precipitation is 47 inches. Stream Restoration Sites - Existing Stream Conditions Harris Creek is a third order tributary to the Second Broad River. The focus of enhancement for the Queens Gap golf course development will be Harris Creek and the unnamed tributaries to Harris Creek. These include UT1 - UT6. The Harris creek watershed has been manipulated from past mining and regional logging practices. Specific reaches show degradation and entrenchment due to these past disturbances. Multiple bank failures are causing erosion and contributing excess sediment to the watershed. The watershed is comprised of Rosgen classified B4, B4a, B5, C5b, and C4 streams. The substrate type for these streams is predominately gravel; however, silt has filled in pools decreasing habitat complexity in some of the lower reaches in the watershed. Harris Creek flows in a southeast direction through the Queen's Gap property, draining a 2.0 square mile watershed. Approximately 6,550 linear feet of stream was surveyed on Harris Creek; it has been divided into three separate reaches to account for the added stream flow. The first reach is the upper Harris Creek reach from Station 0 to the confluence with UT 4 at Station 1550 (see Attachment B). This section of Harris Creek is steep with little sinuosity and is classified as a Rosgen CO channel. It drains a 0.97 square mile watershed. This upper reach has been altered and moved back and forth to allow for mining. The bank height ratio is 1.4 indicating a moderately incised stream. Reach two of Harris Creek extends from UT4 to UT2 (Station 1550- 4500) (see Attachment C). It drains a 1.3 square mile watershed. This reach is classified as a Rosgen C4 channel. It is moderately incised with a bank height ratio of 1.6. Although only moderately entrenched, this reach is continually down-cutting and contributing a large amount of sediment to the watershed. It is characterized by failing vertical banks and undercuts throughout its length. The majority of this reach is disconnected from the floodplain. The third reach of Harris Creek extends from UT2 to the property line (Station 4500 - 6500) (see Attachment D). It drains a 2.0 square mile watershed. This reach is similar in character to the upstream reach and is classified as a Rosgen C4 channel. It is moderately incised with a bank height ratio of 1.8. Banks are vertical and need to be re-sloped to control erosion in key areas, such as in major bends in the channel. UT 1 flows southwest into UT2 draining a 0.13 square mile watershed (See Attachment E). This is a 1,233 foot reach that is characterized as a Rosgen C4 stream type. The bank height ratio is 1.3 indicating a slightly incised stream. There are multiple bank failures, debris jams, and undercuts contributing excess sediment to the system. UT2 flows southwest into Harris draining a 0.5 square mile watershed (see Attachment F). Approximately 5,000 linear feet of stream was surveyed and divided into two separate reaches to account for added stream flow. The upper reach starts at Station 0 and continues downstream to the confluence with UT1 at Station 2400. This reach drains a 0.25 square mile watershed and is classified as a Rosgen 134a channel. It is very steep throughout this reach and has a slope of 4.9%. It is severely incised with a bank height ratio of 2.3. The upper 1,500 feet of this stream is confined to a steep and narrow valley broadening at its confluence with UT1. There are multiple bank failures and undercuts that would require re-sloping, stabilization with structures, or root wad placement. The lower reach of UT2 extends from UT1 downstream to Harris Creek (Station 2400- 4936) (see Attachment G). This reach drains a 0.5 square mile watershed and is characterized as a Rosgen C4 channel type. The gradient changes here as the stream leaves its confined valley and enters the Harris Creek floodplain. From Station 3100 to Station 4100, UT2 is slightly entrenched and appears to have been altered or straightened. UT3 flows south into UT2 draining a 0.06 square mile watershed (see Attachment H). This 1,735 linear foot reach of stream is classified as a Rosgen C5b channel. The bank height ratio is 3.86 indicating channel incision. A wooded buffer protects UT3; therefore, the banks are relatively stable with the exception of a few areas. Lower UT4 (Station 1300- 2400) drains a 0.19 square mile watershed and is characterized as a Rosgen B4 channel (see Attachment I). The bank height ratio is 1.7. The first 400 feet of stream has multiple bank failures that will require resloping and hard structures to prevent further sediment input. UT5 flows south into UT4 and drains a 0.13 square mile watershed (see Attachment 3). This 618 linear feet reach is classified as a Rosgen B4 channel. The bank height ratio is 3.7 indicating a severely incised channel. Vertical banks are failing and would benefit from re-sloping. Habitat complexity is lacking in this reach and would benefit from adding more pools. UT6 (below the pond) flows in a southeast direction into Harris Creek (see Attachment K). This reach is 1,176 linear feet and drains a 0.14 square mile watershed. UT6 is classified as a Rosgen B5 channel and has a bank height ratio of 1.63 indicative of a moderately incised channel. This reach, below the impoundment, has steep banks that need to be re-sloped and stabilized to reduce erosion. Reference Reach Two reference reaches were used as templates to emulate stable dimension, pattern, and profile for enhancement work. Both reference sites are in the same hydrophysiographic region and have a similar valley type. Two sites were chosen to match the specific watershed. Morgan Creek represents a stable meandering B4 channel with a 0.14 square mile watershed. The entrenchment ratio is 2.0, width to depth ratio is 18.4, and sinuosity is 1.5. Pool to pool spacing is 33 feet and provides adequate habitat complexity. A summary chart including a longitudinal profile, cross sections, and pebble counts is attached for review (see Attachment L). A section of Harris Creek was used as a larger reference reach. It is a stable C4 channel with a 2.0 square mile watershed. Entrenchment ratio is 4.6, width to depth is 26.1, and sinuosity is 1.2. Pool to pool spacing is 73 feet. A summary chart including a longitudinal profile, cross sections, and pebble counts is attached for review (see Attachment M). Enhancement Plan Devin McCarthy Land Development, LLC plans to enhance a total of 15,741 linear feet of stream within the Queens Gap project area. 8,518` will be eligible for mitigation with a full 50' unimpacted buffer on each side (see Attachment N). The goals of the project are: 1. Restore natural channel dimension and profile. 2. Reconnect existing incised channels to their floodplain. 3. Stabilize banks and reduce erosion. 4. Create and preserve a riparian buffer with permanent native vegetation. 5. Create aquatic habitat and complexity. Construction Plan and Specifications All reaches within the Queens Gap golf course project boundary will have some degree of enhancement done to them. Construction activities will include the installation of j-hooks, cross vanes, and root wads, and the systematic re- sloping of banks. Caution will be taken to minimize destruction of mature trees within the enhancement areas. A description of each treatment is described below. Root Wads Root wads include the root mass or root ball of a tree plus a portion of the trunk. Roots wads are used to armor a stream bank by deflecting stream flows away from the bank. They also provide structural support to the stream bank, habitat for fish and other aquatic animals, as well as, a food source for aquatic insects. (NCSU) Roots wads will have a basal diameter of 10 to 20 inches. They will be installed where the thalweg intercepts the bank at an acute or right angle. The root wads will be installed at the toe of the bank, with 1/3 of the root wad below the base flow elevation. Footer logs and boulders will be utilized when necessary to secure the root wads in place. The drive-point method of installation will be used whenever possible. With this method, the contractor sharpens the end of the log and drives the root wad directly into the bank. If root wads cannot be driven into the bank, then the trenching method will be utilized. This method requires digging a trench and placing the log into the trench. The trench is then backfilled, re-sloped, and planted. Rock Vanes The three types of rock vanes are single vanes, 3-hooks, and cross vanes. Rock vanes are most often constructed of boulders, although they can be constructed of other natural materials, such as wood. Vanes protect the stream bank by redirecting the thalweg away from the stream banks and towards the center of the channel and improve in-stream habitat through scour oxygenation, and cover. (NCSU) All rock vanes will be oriented upstream with angles off the bank from 20 to 30 degrees. Vanes will be located just downstream of the point where the stream flow encounters the stream bank at an acute angle. The vane will start at or near bankfull and slope downward into the channel, pointing upstream. Sills will be used to tie the vane arms to the bankfull elevation. Large, flat rocks will be used to construct the vanes. Single vanes will span 1/2 to 2/3 of the base flow channel width. Slopes on the vanes will range from 2 to 7 percent. Longer, flatter vanes will be utilized whenever possible. Boulders in the vanes will fit tightly together and footer rocks will be utilized to ensure scour does not topple the structures. 3-hooks will be constructed the same way as a single vane except the last rocks in the structure will be spaced apart about half of the rocks diameter to create flow convergence. Cross vanes will be used to provide grade control, keep the thalweg in the center of the channel, and protect the bank. The cross vane will be constructed as if it is two single vanes with a center structure perpendicular to the channel flow. The center stone will set the invert grade of the streambed. Toe Armor Toe armor will be used where banks are undercut or failing and due to the landscape it is not practical to re-slope the banks. Large stones will be placed in these undercuts and failures. Where banks are being rebuilt, filter fabric will be placed behind the stones to prevent wasting of backfill material. Re-slope Banks In areas where the banks can be re-sloped, this method will be used instead of toe armor. Vertical banks will be graded at a slope of 2:1 or flatter. Where appropriate, accessible bankfull benches will be established to reduce sheer stress on banks. Newly sloped banks will be graded into the existing stream banks. Any disturbed soil will be stabilized with erosion matting and planted with native vegetation. UT1 0+00-12+33 Six sites on UT1 have been identified for treatment. Toe Armor will be placed at Stations 1+25 and 7+50. Station 10+45 will be treated with a cross vane. Stations 1+40, 6+35, and 10+90 will be treated with 3-hooks. Root wads will be installed at stations 0+25 and 11+35. All treatment areas have been identified on the attached map (see plans) and construction typicals for each structure have been included. UT2 Reach Upper 0+00 - 24+00 The upper reach of UT2 includes twelve structures and two root wads throughout 1800 feet of enhancement. Cross vanes will be placed at Stations 1+30, and 16+35. J-hooks will be placed at Stations 0+90, 7+85, 11+25, 11+85, 13+15, 18+10, 20+20, 21+50, and 21+75. Root wads will be used to stabilize undercuts at Station 14+85 and Station 18+35, and toe armor will be placed at Station 21+65. (see plans). UT2 Reach Lower 24+00 - 50+00 The lower reach of UT2 includes twenty-three structures, nine rood wad placement sites, and two toe armors. Cross vanes will be installed at Stations 24+10, 24+40, 26+25, 27+40, 28+15, 30+65, 31_85, 37+65, 38+50 and 42+10. Stations 26+65, 28+85, 30+85, 32+50, 33+86, 34+40, 36+35, 38+00, 43+50, 46+35 and 47+40 will require J-hooks to redirect the water away from the banks. Stations 35+85, and 45+20 will receive toe armor. Stations 24+50, 31+25, 35+75, 37+00, 41+75, 42+60, 43+85, 46+90, and 47+85 will be armored with root wads to prevent bank erosion. Some of these root wad sites will be made up of clusters of two to four root masses (see plans). UT3 0+00-17+35 UT3 has several bank failures that will require stabilization (see plans). Being re- sloped or having a bankfull bench cut will enhance most spots. Native vegetation will be planted to stabilize each failure. UT4 13+00-17+00 In addition to re-sloping and re-vegetation, UT4 will receive three J-hooks at Stations 13+65, 13+85, and 16+15, and a root wad at Station 16+00. (see plans). UT5 0+00-6+18 UT 5 has six structures and two root wads planned for treatments. Stations 0+25 and 2+60 will be treated with root wads. Stations 2+00, 3+00, 3+30, 4+70, 5+15, and 5+65 will be treated using structures such as j-hooks or log vanes. The remaining bank failures will be re-sloped and a bankfull bench will be added and planted with native vegetation. All treatment areas have been identified on the attached map and construction typicals for each structure have been included as (see plans). UT6 0+00-12+00 (Below Dam) Fourteen sites have been identified for treatment along UT6. Two areas will require re-sloping and having bankfull benches cut; however the majority of work will be installation of structures. Stations 2+85, 5+50, 11+25 and 11+50 will be treated with root wads strategically placed to displace shear velocity on the banks. Structures such as j-hooks or log vanes will be placed at Stations 3+80, 4+40, 6+35, 6+65, 7+50, 7+85, and 11+75. A full cross vane will be placed at Station 9+10. All treatment areas have been identified on the attached map and construction typicals for each structure have been included as (see plans). Upper Harris Creek (Above UT4) Station 0+00 - 15+50 There are fifteen sites along Upper Harris Creek that have been selected for treatment. Root wads will be placed at stations 0+50, 1+80, 2+50, 3+10, 3+50, and 4+50. Structures such as cross vanes, J-hooks and log vanes will be placed at stations 0+15, 0+70, 1+65, 2+00, 2+95, 3+20, 4+25, 5+10, and 6+75. All treatment areas have been identified on the attached map and construction typicals for each structure have been included. (see plans). Middle Harris Creek (Between UT4 and UT2) Station 20+00 - 44+00 There are twenty-three sites on Middle Harris Creek that have been identified for treatment. Root wads will be strategically placed to prevent erosion at stations 23+25, 23+75, 25+00, 26+50, and 27+25. Structures such as 3-hooks, log vanes, or cross vanes will be used to redirect flow away from the banks at stations 20+40, 20+65, 21+15, 22+30, 23+00, 24+80, 25+15, 26+00, 28+10, 29+30, 30+45, 31+15, 31+85, 32+40, 37+00, 37+35, 38+00 and 41+00. All other bank failures will be re-sloped and bankfull benches will be cut to allow access to the floodplain. All treatment areas have been identified on the attached map and construction typicals for each structure have been included. (see plans). Lower Harris Creek (Below UT2) Station 44+00 - 65+00 There are thirteen sites on Lower Harris Creek that have been identified for treatment. Stations 59+10 and 59+60 will be treated with root wads. Stations 47+85, 49+70, 51+10, 52+65, 53+45, 54+55, 55+30, 56+00, 58+15, 58+85, and 59+50 will be treated using structures such as cross vanes, j-hooks or log vanes. All other bank failures will be re-sloped and bankfull benches will be cut. All treatment areas have been identified on the attached map and construction typicals for each structure have been included. (see plans). Monitoring Plan After construction completion, WNR staff will provide the resource agencies with a baseline monitoring report. Monitoring activities will take place every year for 5 years after construction completion. An annual monitoring report will be submitted each year following the monitoring activities. WNR will conduct monitoring and Devin McCarthy Land Development, LLC will provide the financial assurance that will ensure this project is complete and successful. An as-built report will be included with the first annual monitoring report. At least two bankfull events in separate years will be documented within 5-year monitoring period. If two bankfull events have not been documented, stream monitoring will continue until two bankfull events have occurred in two separate years. Success will be measured in terms of channel stability and plant survival. Problem areas identified during any part of annual monitoring activities will be discussed with project partners. Any necessary remedial actions will be planned, approved, and implemented. Monitoring Parameters 1.0 Channel Stability 1.1 Cross Sections 1.2 Longitudinal Profile 1.3 Pebble Counts 2.0 Plant Survival 2.1 Monitoring Plots 3.0 Photographic Reference Sites 4.0 Biological Monitoring 1.0 Channel Stability Channel stability will be measured through the following three parameters: cross- sections, longitudinal profiles, and pebble counts; and then compared to previous measurements. A minimum of two permanent cross-sections will be taken per 1,000 linear feet of stream representing 50% pools and 50% riffles. Pebble counts will be performed at each cross section. A longitudinal profile will be conducted to monitor any changes in profile. If the reach is less than 3,000 linear feet, then all 3,000 feet will be surveyed. If the reach is greater than 3,000 linear feet, then the profile will include 30% of the restored stream or 3,000 linear feet (whichever is greater). If there is substantial evidence of instability, such as down-cutting or erosion, remedial actions will be taken. 2.0 Plant Survival Vegetative success will be measured in terms of plant survival. Plant survival will be measured with stem counts in designated vegetative monitoring plots. Stem counts of at least 320 stems/acre in year 3 and 260 stems/acre in year 5 will be considered successful. Vegetative monitoring plots, 1/10 acre in size, will be set up adjacent to each cross section. Plant survivability will be assessed using these vegetative monitoring plots. If there is substantial plant mortality that leads to lowered stem counts, remedial actions will be taken. Areas with less than 75% vegetation coverage will be re-seeded and/or fertilized; and live stakes and bare rooted trees will be planted to achieve the desired densities. Exotic, invasive, and invader species will be removed so that they will not exceed 20% of the vegetative composition. 3.0 Photographic Reference Sites Photos will be taken at each cross section as well as other monumented reference sites throughout the restoration reach. These photos will indicate aggradation, degradation, and/or bank erosion. If none exists, no remedial action will be required. If aggradation, degradation, and/or bank erosion occurs, the problem will be accessed and remedial actions will be planned, approved, and implemented. 4.0 Biological Monitoring Benthic macroinvertebrate sampling will be conducted before the project and will continue for at least three years of monitoring after project completion.
