EEP Floodplain Requirements Checklist 4 i ®~_.~~, i~ ' Executive Summary The project site and easement is located on the Steven Faw property (PIN # 3999252005), at 541 Dewitt Road, approximately 4 miles south of Sparta, North Carolina. The project reaches include the portion of Glade Creek that flows through the Faw property as well as an unnamed tributary that flows through the property and exits the property just before its confluence with Glade Creek. The total existing channel ' length on Glade Creek is 2,569 feet (thalweg) based on survey data and stationing. The unnamed tributary (UT) to Glade Creek is 1,088 feet long based on the survey. There is 0.17 acre of wetland that has been delineated beside the main channel of Glade Creek and 0.16 acre of wetland that has been delineated on the upper section of the UT, for a total of 0.33 acre of delineated wetland on the project site. Glade Creek and the downstream portion of the UT channel are currently unstable, with an over-wide channel in many areas, mid-channel sediment bars, incised bed and steep, eroding, unvegetated banks r throughout. Approximately 62% of the Glade Creek channel within the project boundary has a BEHI rating of High, 33% has a rating of Very High and 5% has a rating of Moderate. The estimated total sediment export per year for the Glade Creek reach is 619 tons, based on the Rosgen (2004) sediment export curves. The entire proposed restoration reach of the unnamed tributary has a BEHI rating of Very High, and the estimated total sediment export per year for the reach is 72 tons. The pervasive extent of high BEHI scores indicates that the channel is widening and migrating throughout most of the project reaches. Approximately 70% of the channel on Glade Creek had bank height ratios (BHR) of 2 or more and all of the channel proposed for restoration on the UT has a BHR of >2. A bank height ratio greater than two indicates a highly erosive condition for stream banks by definition, so field review of the channel indicates that it has experienced extensive incision and entrenchment. These conditions will become stabilized on their own only through the natural reconfiguration of the channel from bankfull flows, which takes place over many years and introduces very large amounts of sediment from the bed ' and banks into the stream flow and aquatic habitat as the channel readjusts its geometry and course. The goals of the project are to: • Rapidly stabilize the channel of Glade Creek relative to natural process, • Rapidly stabilize and preserve the channel of the UT relative to natural process, • Restore and rehabilitate channel features and aquatic habitat in Glade Creek and the UT, • Rehabilitate the riparian buffer along both streams, • Preserve the existing wetlands onsite. 1 These goals will be accomplished by designing and constructing a stable plan, profile and dimension for the stream channels and re-establishing continuous riparian buffers along the banks. Project implementation will greatly reduce bank erosion and consequently decrease the amount of sediment load in the stream at flows above baseflow. Restoration level (Rosgen Priority Level II) design is needed on all but 125 feet (which will be Enhancement I) of the channel on the project, due to unstable channel geometry, sinuosity and streambank steepness. Structures will be used to enhance holding and feeding areas for trout. Riparian buffer vegetation will be established to provide food and cover for terrestrial fauna and to provide a carbon source and shade for aquatic habitat. Through its Local Watershed Planning initiative, EEP focuses resources in specific 14-digit hydrologic units -local watersheds - in order to address critical watershed issues. This process involves conducting a detailed assessment of the condition of the watershed, involving the local community in identifying solutions to water-quality, habitat and flooding problems, and working to get agreed-upon solutions implemented within priority sub-watersheds. Stream restoration on Glade Creek will help alleviate two problems identified in the Local Watershed Plan for the Little River (Phase I) as being sources of water quality degradation-inadequate riparian buffers and sediment. This project would address both of those 1 problems by stabilizing the severely eroding stream banks onsite and establishing a permanent riparian buffer on them. 1 1 1 1 1 1 i 1 To meet the goals listed above, the proposed objectives for Glade Creek are to perform Priority II Restoration on approximately 2,430 linear feet (LF) and stabilize 125 LF with Enhancement I design. Please note that a 25-foot section of channel underneath the existing bridge was excluded from the proposed restoration total, although channel profile and dimension will be reconfigured and stabilized. The proposed objectives for the UT are to perform Restoration on approximately 275 LF and Preserve 788 LF. All the wetlands onsite will be preserved with the proposed project (see Table 1). Table 1.

The project reaches include the portion of Glade Creek that flows through the Faw property as well as an unnamed tributary that flows through the ' property and exits the property just before its confluence with Glade Creek. The total existing channel length on Glade Creek is 2,550 feet (thalweg) based on survey data and stationing. The unnamed tributary to Glade Creek is 1,088 feet long based on the survey. The latitude and longitude of the midpoint of the restored mainstem is 1392171.90N, 995691.64E using the NAD83 coordinate system. For the tributary section the coordinates are 1392799.71N, 995076.13E. For the wetland on Glade Creek the coordinates for the approximate center are 1392253.65N, 995752.46E 1.1 Directions to Project Site i The project site is located in Alleghany County, North Carolina, approximately 4 miles southeast of the town of Sparta. From the south and east, the site can be accessed by exiting Interstate 77 North at the US 21 Bypass exit in Elkin and traveling 23.1 miles to Dewitt Road, turning left on Dewitt Road ' and traveling 0.7 miles to the site entrance on the left at 541 Dewitt Road. From the north and west, proceed south on US 21 4 miles to Dewitt Road, turn right and proceed 0.7 miles to 541 Dewitt Road on the left. 1.2 IISGS Hydrologic Unit Code and NCDWQ River Basin Designations Glade Creek is located in the USGS 8-digit Hydrologic Unit Code 05050001, and in the 05050001030020 14-digit Code. The N.C. Division of Water Quality stream index number for Glade Creek is 10-9-9. This stream is classified as Class C trout water. 1.3 Project Vicinity Map See Figure 1 (Section 10). ' 2.0 Watershed Characterization ' The Glade Creek watershed is located in a rural area of a sparsely populated county. County land area is 235 square miles. The population of Alleghany County as of the 2000 Census was ] 0,677, rendering a population density of 45 persons per square mile, approximately 23 percent of the state average of l 65 ' persons per square mile. The average temperature is 50.1 degrees Fahrenheit, the average annual rainfall is 46 inches and the average annual snowfall is 17 inches. (Alleghany County Demographics, http://eal leghany.net/main/demographics/) ' 2.1 Drainage Area The drainage area of the main channel of Glade Creek at the downstream end of the project is 2,922 ' acres (4.6 mi') and the drainage area of the unnamed tributary at the downstream end of the project is approximately 521 acres (0.8 mi2), for a total watershed area of approximately 3,443 acres (5.4 mi'). The area within the conservation easement or project area itself is approximately 12 acres. 2.2 Surface Water Classification /Water Quality Glade Creek is located in the USGS 8-digit Hydrologic Unit Code 05050001, and in the 05050001030020 14-digit Code. The N.C. Division of Water Quality stream index number for Glade Creek is 10-9-9. This stream is classified as a Class C trout water. 2.3 Physiography, Geology and Soils Alleghany County is located in northwestern North Carolina, and its northern border is with Virginia. The county is located entirely within the Appalachian Mountains region of western North Carolina. Most of the county is located atop a rolling plateau that ranges from 2,500 feet to 3,000 feet above sea level. The Glade Creek watershed is part of the area, and is underlain by sedimentary and metamorphic rock from the late Proterozoic Period, clastic metasedimentary rock, and mafic and felsic metavolcanic rock of the Ashe Metamorphic Suite, Tallulah Falls Formation and Alligator Back Formation, gneiss, schist, metagraywacke, amphibolite, and calc-silicate granofels (N.C. Geological Survey, 1985). The NRCS is currently working on a revision of the soil survey of Alleghany County, and limited information is available on the Web Soil Survey 2.0 website. However, Biohabitats was able to get GIS soils information from the 1973 Soil Survey from the State NRCS office and analyze it. The results for the combined Glade Creek and unnamed tributary watersheds are listed below. Series Name Acres Percent Series Name Acres Percent 1. Watauga 1 512.0 43.9 8. Fannin 75.1 2.2 2.

Water 1.6 0.0 TOTALS 3 446.2 100 ' By far the most prevalent soil series in the watershed is the Watauga series (44%, Typic Hapludults) followed by Chester (16%, Typic Hapludults) and Porters (l2%, Typic Dystrudepts) soils. All these series are upland soils, and no hydric soil is included in the list, although it is assumed that the alluvial land category may contain hydric soils. 2.4 Historical Land Use and Development Trends The main land use patterns for the Glade Creek watershed upstream of the project are approximately 44% (1,500 ac) Managed Herbaceous Cover (pasture), and 36% (1,226 ac) forested in Mixed Upland ' Forest (see Table 3 in Section 9). A major component of Allegheny County's economic history and present economy is dairy and livestock production. The high percentage of pasture in the watershed reflects this economic trend. A major cause of accelerated stream bank erosion can be related to land ' use change (Henderson, 1986). For decades livestock and dairy production has known to compact soils, increase stornwater runoff and increase sediment loading in stormwater. For example, overgrazing and soil compaction in the uplands often lead to rill erosion and elevated peak flows instream. Soil can become compacted by the repeated pressure of moving animals, especially if the i soil is wet. The combination of soil exposure and compaction can decrease infiltration and increase surface runoff. If infiltration capacity is severely limited on a large fraction of a catchment, the extra ' runoff can quickly enter streams and generate higher peak flows (Davis, 1977.) The high percentage of land in the watershed converted to pasture indicates a high potential for non-point source runoff and pollution to be generated upstream of the site and transported downstream. Only 0.5% of the ' watershed is in cultivated land, the balance of the remaining land being in forest, shrub or herbaceous cover. In addition to erosive impacts caused by livestock and dairy production, research has shown that ' stream erosion can be caused by logging done without following Best Management Practices. Rice et al. (1979) and Burwell (1970) showed that the quantity of sediment produced and delivered to a stream from a logging site is determined to a large extent by the care taken by the harvesting operator. ' Toews and Moore (1982) reported stream bank erosion was more than 250% greater after logging than before in clearcut areas where no buffer strips were left. After clearcutting an area where a buffer strip 5 meters or less was used, streambank erosion increased only 32% over the preharvest rate. ' Logging was historically common throughout the mountains of North Carolina, and based on the degree of incision of the restoration reach, the Glade Creek watershed was no exception. Best Management Practices were only developed and mandated for use in the past 20-30 years. Projected population growth for the state of North Carolina from 2000 to 2006 was 10.1 % while Allegheny County's population was projected to grow by 3%, indicating a suppressed population and development growth compared to the state as a whole (N.C. State Demographics, 2007). From the same data source, the projected growth rate from 2010-2020 was projected to be low, approximately 3%. The population growth for Sparta, NC from 2000-2007 was 2.3% (http://www.bestplaces.net/zip- code/Sparta_NC-72867500000.aspx). However, there are 2.5 Endangered /Threatened Species A visual site assessment was conducted by traversing the entire project site. Biohabitats inspected the site for any indication of suitable habitat for any listed species. Based on the visual assessment results, Biohabitats determined if the project may affect one or more federally listed species or designated critical habitats. Prior to the site visit, we obtained an updated species list for Allegheny County from the US Fish and Wildlife Service web site (http://nc-es.fws.gov/es/countyfr.html).

Endangered (E), Threatened (T), and Special Concern (SC) species are protected by state law (Plant Protection and Conservation Act, 1979). Candidate and Significantly Rare (SR) designations indicate rarity and the need for population monitoring and conservation action. The additional significantly rare designations "-P" and "-O" refer to species at the periphery of their range in North Carolina, and that the range of species is sporadic or cannot be described by other significantly rare designations, respectively. Note that plants can have a double status, e.g., E-SC, indicates that while the plant is endangered, it is ' collected or sold under regulation. Animal statuses for the NHP list are determined by the Wildlife Resources Commission a11d the Natural Heritage Program. Endangered, Threatened, and Special Concern species of mammals, birds, reptiles, amphibians, freshwater fishes, and freshwater and terrestrial mollusks have legal protection status in North Carolina (Wildlife Resources Commission). The Significantly Rare designation indicates rarity and the need for population monitoring and conservation action. ' There are no federally endangered species listed for Alleghany County. There is one federally threatened species listed for this county, the Bog turtle (Clemmys muhlenbergii). The Bog turtle has a shell length of approximately 4 inches with a distinctive red, orange, or yellow patch on each side of ' the head.. The Bog turtle has a light brown to ebony shell. 12 Bog turtles inhabit slow, shallow, muck-bottomed rivulets of sphagnum bogs, calcareous fens, marshy/sedge-tussock meadows, spring seeps, wet cow pastures, and shrub swamps; the habitat usually contains an abundance of sedges or mossy cover. The turtles depend on a mosaic of microhabitats for foraging, nesting, basking, hibernation, and shelter (USFWS, 2000). "Unfragmented ' riparian systems that are sufficiently dynamic to allow the natural creation of open habitat are needed to compensate.for ecological succession" (USFWS, 2000). Beaver, deer, and cattle may be instrumental in maintaining the essential open-canopy wetlands (USFWS, 2000). Bog turtles rarely leave wetland habitats, although recent radio-telemetry evidence indicates that bog turtles sometimes venture into and across upland habitats (375 m, Carter et al., 2000) and cross roads to reach adjacent wetlands (Morrow et al. 2001). Whitlock (unpublished data) also documented individuals regularly moving back and forth across 1 km of a typical wetland habitat to more suitable habitat patches. Successful movement across developed areas is probably negligible, due to susceptibility to collection, predation, and road mortality. In North Carolina over somewhat less than l year, distances between relocations ofradio-tagged turtles ranged from 0 to 87 m (mean= 24 m) for males, and 0 to 62 m (mean= 16 m) for females ' (Heenan and Fahey, 1992). There are 5 delineated wetlands on the project site, and they are all forested (refer to Section 5.1 and Figure 4), While these forested wetlands are not preferred habitat of the bog turtle, based on current scientific knowledge, they could be used by turtles as they travel between more suitable or preferred ' habitat. Based on personal communication with Dennis Herman of the N.C. Dept. of Transportation Office of the Natural Enviromnent (July 20, 2007), a recognized bog turtle expert, bog turtles probably travel through the site on their way upstream or downstream to other sites, and may use the project site wetlands as stopping-over points. However, since all wetland areas within the project site will be undisturbed during project construction and will be permanently preserved, he stated that he believed that the short term disturbance of project construction would be offset by the long term preservation of the wetlands. Therefore, stream restoration activities associated with the Glade Creek Stream Mitigation site in Alleghany County will have no negative effect on the bog turtle species. ' 2.6 Cultural Resources A visual on-site assessment was conducted by traversing the entire project site thoroughly, on both sides of the streams. No archeological artifacts were observed or noted during the site survey. The Environmental Data Resources, Inc. review for the project site revealed no record of mapped historic ' sites within the project area. The State Historical Preservation Office (SHPO) was contacted and conducted a review of the site. In a response dated March 27, 2007 it was stated that SHPO was not aware of any historic resources that would be affected by the restoration project and that SHPO had no comment on the proposed undertaking. A forma] letter was sent to the Tribal Historic Preservation Office of the Eastern Band of Cherokee Indians on February 22, 2007. The project is still under review and when the letter is received, it will be submitted to EEP. 13 2.7 Potential Constraints 2.7.1 Property Ownership and Boundary The project site and easement is located on the Steven Faw property (PIN # 39992520005), at 541 Dewitt Road, approximately 4 miles southeast of Sparta, North Carolina. The project reaches include the portion of Glade Creek that flows through the Faw property as well as an unnamed. tributary that flows through the property and exits the property just before its confluence with Glade Creek (Figure 3). 2.7.2 Site Access The easement is accessed from. Dewitt Road by crossing the bridge over Glade Creek (the Faw's driveway) and accessing the easement from the side of the creek opposite from Dewitt Road. A temporary construction access road may need to be built from Dewitt Road to the creek if it is determined that the Faw's bridge over Glade Creek is not capable of safely supporting heavy equipment. 2.7.3 Utilities An overhead power line services the property owner's house and passes over the easement. It is the only known utility that passes through the project site. 2.7.4 FEMA /Hydrologic Trespass 1 1 1 As of July 2, 2007, there is no FEMA mapping for the project area, based on a review of the N.C. Flood maps website. The proposed project is a Rosgen Priority II stream restoration project, with no wetland restoration component, only wetland preservation. The hydrology of the site will not be significantly altered by the project. The Faw's property and the adjoining properties will not be hydrologically trespassed upon by the stream restoration project. 2.7.5a. Beaver Pond and Design Approach There is an existing beaver dam and pond along Glade Creek at station 17+75. Beavers built this feature during the fall of 2006 and then enlarged it in the winter of 2007. The proposed design will construct a stable cham~el directing flow beside and around the pond, preserving its present size and configuration. The mud and stick beaver dam will be removed and replaced with somewhat more permanent channel bed material. During higher flows the pond area will serve as additional floodplain capacity, and during low flows the stream thalweg will be adjacent to the pond area, flowing around it. This will allow the beaver impoundment area to persist, with a stable chamlel adjacent to it, thus providing stability while still allowing unimpeded sediment transport in the channel. The water table is expected to be high enough to maintain water in the adjacent pond area during periods of low flow. This design provides a stable channel for stream flow and also maintains the small, ~ 0.1 ac impoundment that beavers have already constructed. According to the land owner, the beaver population is established both upstream and downstream from the project, and beaver are a natural part of the ecosystem. Eliminating them from a limited reach of stream when their population is established immediately upstream and downstream is generally not a reliable 14 1 1 1 1 1 control measure. There is no guarantee that the beavers wouldn't return and build a new dam near the present pond location if it is removed. This design approach, by retaining the impounded water in the existing pond, should allow the beavers to continue limited activity, while discouraging them from building new dams in the project area. 2.7.Sb. Research on Beaver Activity and Stream/Riparian Zone Ecology Much research has been published on the beneficial ecological effects of beaver activity. In the Rocky Mountain region, beaver have been shown to facilitate regeneration of long absent riparian vegetation (if cattle grazing was properly managed), and improve conditions for trout (Smith 1980; Munther 1981; Johnson 1984). Lack of beaver dams and impositionof grazing had led to channel incision and deterioration of trout habitat in the mountain valley creeks. Stocking beaver and initially providing them with aspen cuttings as food. and dam-building material enabled them to impound water, which rejuvenated riparian zones. In such terrain, healing creeks with beaver proved to be more economical than traditional measures (Johnson 1984). Beaver help resist adverse perturbation of riparian areas, and their ponds improve chemical water quality (Parker 1986). The reintroduction of beaver has demonstrated: 1) an elevated water table upstream of the dam, which in turn improves vegetation condition, reduces water velocities, reduces bank erosion, and improves fish habitat (increased water depth, better food production, higher dissolved oxygen, and various water temperatures), 2) reduced sedimentation downstream of the dam, 3) increased water storage, 4) improved water quality, and 5) more waterfowl nesting and brooding areas (McKinstry et al. 2001). In North Carolina beavers have naturally re-introduced themselves, but their effects on the environment are the same as if they were artificially re-introduced, as in much of the published research to date. 15 ' 3.0 Pro'ect Site Streams existin condition 0 7 ~ ~ ~ ( g s) 3.1 Channel Classification As part of the field reconnaissance, the Rosgen classification system (Rosgen, ] 994) was used to ' determine channel type at each field cross section on the basis of existing morphological features of the stream channel. Two stable, representative riffle cross sections were surveyed on Glade Creek. The measured channel dimensions for the representative cross sections generate a C4 classification; except for width/depth ratio at the cross sections were 9.1 and 11.1, just under the classification minimum for a C channel, which is l2. A width/depth ration of less than 12 is characteristic of an E channel. For this reason, the existing channel is classified as a CE4 channel, in deference to the low width/depth ratios at these representative riffles. However, in other sections of the Glade Creek 1 channel, where downcutting and widening have occurred, decreasing the entrenchment ratio and increasing the width/depth ratio, the channel classification is F4 or G4. The F4 and G4 classifications are indicative of channel instability. Only one stable, representative cross section could be located on ' the unnamed tributary. Based on the measurements taken in the field, the unnamed tributary also was classified as a C4. 3.2 Discharge In adjustable, alluvial, transport-limited rivers in temperate climates, flows of moderate frequency ' (e.g., the 1.5- to 2-year storm event) and magnitude perform most of the geomorphic work (Wolman and Miller, 1960). This concept of the "dominant discharge" provides a statistical index for the flow that corresponds with the peak volume of sediment transported. Dominant discharge is the maximum possible product of the frequency of a flow occurrence and the amowlt of sediment transported by that flow event. Channel morphology is ultimately a result of all flows above a sediment transport threshold that do some geomorphic work. However, the dominant discharge is commonly used as a single-value estimate for a flow that may be largely responsible for resulting geomorphic form. It is thought that, in many cases, the morphological feature of a bankfull elevation corresponds fairly well to the flow stage of the dominant discharge. This has led to the concept of bankfull elevation as a tool in stream restoration design. However, the concept should be applied cautiously in stream restoration design. It should be noted that as channel boundaries are more resistant or less adjustable (i.e., bedrock, hillslope constraints, or large bed material) or in more arid environments, the majority ' of geomorphic work is more likely to be performed by larger and rarer flood events. For the purposes of this restoration plan, here the bankfull discharge is considered to be essentially equivalent to the dominant discharge, and serves a guiding value in many aspects of the restoration design. As mentioned in Section 3.1, the bankfull elevation was identified in the field by Biohabitats personnel at surveyed cross sections. The bankfull elevation at each cross section was derived from all available indications including depositional features, changes in bank angle, vegetation, scour lines, and storn~ debris lines. Bankfull discharge was estimated by solving the Manning equation for discharge given the bankfull elevation, local channel geometry, slope, and roughness. Channel roughness, represented by Manning's "n", was approximated using the standard references Chow (1959) and Barnes (1967) based on field observations of bed material, channel geometry, and adjacent riparian vegetation. 1 For the purpose of comparison, a predicted bankfull discharge was also calculated for Glade Creek and the unnamed tributary using available North Carolina regression relationships for rural streams in the Mountain physiographic province (Harman et al., 1999). The rural regression relationships are expressed by the following equations: Abkf - 22.1 AH, 0.67 Qbkf - 11 S.7 AW 0.73 ' Wbkf - 19.9AW 0.36 Dbkf = 1.1 AW 031 where AW is watershed area in square miles (min), Abkr is the bankfull cross-sectional area in square feet (ft~), Qb~ is the bankfull discharge in cubic feet per second (cfs), Wbkr is the bankfull width in feet (ft), and Dbkr ~s the bankfull mean depth m feet (ft). For the purpose of comparison, a predicted bankfull discharge was also calculated for Glade Creek and the unnamed tributary using available North Carolina regression relationships for rural streams in the Piedmont physiographic province (Harman et al., 1999). The rural regression relationships are expressed by the following equations: Abkr = 21.43 AW o.bs Qbkr = 89.04 Aw. °.72 Wbkf = 1 1.89A,,, 0.42 Dbkf = 1 •SOAW 032 The discharge was also estimated using the hydrologic model TR-20. The results of deriving Qbkr from the different methods are listed below, along with the chosen design discharges. Stream Bankfull Discharge Peak Flow, Design Manning's E uation Mountain Regional Curve Piedmont Re Tonal Curve TR-20 Discharge Glade Creek Dischar e (cfs) X/S l :228 3S2 267 1- r: 204 200 X/S 2: 1S3 2- r: 33S Unnamed Tributa Discharge (cfs) 27 98 76 1-yr: 16 20 2-yr: 23 The existing channel cross section geometry data was used in the Manning's Equation and TR-20 estimates, making those estimates site specific. Bankfull indicators were more reliable at cross section 1 on Glade Creek. The Manning's Equation estimate at cross section 1 also falls within the bounds of the 1-year and 2-year discharge predictions from the TR-20 model output. The Regional Curve predictions are above the Manning's and TR-20 values, but the Manning's and TR-20 values fall reasonably within confidence intervals on the Piedmont curve, and within a reasonable range on the Mountain Curve. Therefore, the design discharges were determined using a combination of the Manning's Equation and TR-20 estimates. 3.3 Channel Morphology (pattern, dimension, profile) The existing channel morphology exhibits several Rosgen Classifications over the project reaches of Glade Creek and the unnamed tributary (channel geometry is summarised in Table 4)._ The diagnostic classification, measured at stable riffle cross sections for both Glade Creek and the unnamed tributary is C4. C4 is what the entire channel would have been classified as before it experienced degradation. 17 ' However, the majority of the project channel reaches have experienced over-widening and incision, probably due to long-term increasing flows from forest conversion to pasture land upstream and from relatively short-lived increased runoff from clear-cutting in the watershed, and are classified as F4 and G4. The existing C4 channel has a sinuosity of 1.2, a riffle cross sectional area of approximately 5 l ftZ, and an average slope of 0.005. 3.4 Channel Stability Assessment The entire Glade Creek reach and the downstream reach of the unnamed tributary that are proposed for restoration/enhancement were assessed in the field by Biohabitats using the Bank Erosion Hazard 1 Index (BEHI) (Rosgen 2001). Approximately 62% of the Glade Creek channel within the project boundary has a BEHI rating of High, 33% has a rating of Very High and 5% has a rating of Moderate (see Table 5). The estimated total sediment export per year for the Glade Creek reach is 619 tons, based on the BEHI methodology and sediment export curves. The entire proposed restoration reach of the unnamed tributary has a BEHI rating of Very High, and the estimated total sediment export per year for the reach is 72 tons. The pervasive extent of high BEHI scores indicates that the channel is ' widening and migrating throughout most of the project reaches. Bank height ratios (BHR) were estimated while performing the BEHI analysis. Approximately 70% of the channel on Glade Creek had BHR's of 2 or more and all of the channel proposed for restoration on the UT has a BHR of >2. In the BEHI protocol, a bank height ratio greater than 1.5 is an indication of highly unstable banks. Bedrock is present in a limited number of locations throughout the project reaches, but bank height ratios are greater than 1 throughout most of the project, and approach and exceed 2 in some places, indicating instability and downcutting of the channel. 3. S Bankfull Verification The 1-and 2-year water surface elevations predicted by HEC-RAS were compared with bankfull flows calculated based on field indicators using the Manning equation to help calibrate bankfull discharge estimates to be used in channel design. At both representative riffle cross sections on Glade Creek, the maximum depth predicted by the HEC-RAS program using the TR-20 discharge estimate coincided well with the maximum depth at the surveyed cross sections using the Mannings Equation discharge prediction, listed below. Cross Section Mannings Eq. Q (cfs) TR-20 Q (cfs) HEC-RAS dmax (ft) Surveyed d,nax (ft) Glade 1 228 1- r: 204 2.55 2.8 2-yr: 335 3.33 Glade 2 153 1- r: 204 2.36 2.4 2-yr: 335 3.14 Unnamed Tributary 27 1-yr: 16 0.56 1.0 2- r: 23 0.71 At the unnamed tributary cross section, the correlation was not as close, but it was within 0.4 ft of the midpoint between the two discharges. Therefore, the identified bankfull indicators in the Feld correlate well with the predictive estimates generated by Mannings Equation and HEC-RAS. In addition, the predicted discharges correlate well with the bankfull channel geometry identified in the field. 18 3.6 Ve etation g ' The riparian area along Glade Creek is in a relatively undisturbed, natural condition. The dominant canopy species there are white oak (Quercus alba), white pine (Pinus strobus) and red maple (Ater rubrunr). The two dominant species in the understory/shrub layer are rhododendron (Rhododendron maximum) and mountain laurel (Kalmia latifolia). Other understory species included smooth alder (Alms serulata), black cherry (Prunus serotina), multiflora rose (Rosa mult~ora), and black willow (Salix nigra). The herbaceous layer, where the canopy is closed, is not present, but where there are openings it contains many grasses, including fescue (Festuca sp.), blackberry bushes (Rubus sp.) and various wild flowers, dominated by the Asteracae family. 1 1 1 19 . 1~L 4.0 Reference Stream Basin Creek, located in Wilkes County in Doughton State Park, was used as the reference stream (Figure 5). It was surveyed by a team of NRCS and NCWRC personnel (Angela Jessup, Dick Everhart, Greg Goings, Jerry Pate and Joe Mickey) and by an NC SRI crew (Dan Clinton, Jan Patterson, Louise O'Hara and Jon Williams) in 1998. The original survey data from both surveys was acquired from the NC SRI. The data generated from those surveys was compared and used for design purposes. Biohabitats reviewed the stream in the field in May 2007 and determined from a walk of the stream from the downstream boundary of Doughton Park to above the confluence of Cove and Basin Creeks (approximately 2 miles of stream), that it was a stable, suitable reference reach. 4.1 Watershed Characterization The Basin Creek watershed was delineated (see Figure 6) and the land uses within it are summarized below. The watershed is approximately 98% forested, and less than 1 % developed. Land Use In Basin Creek Watershed (Reference) Land Use Acreage Deciduous Forest 3,963.2 91.3 Mixed Forest 139.2 3.2 Evergreen Forest 119.9 2.8 Pasture/Hay 59.2 1.4 ' Developed Open Space 20.7 0.5 Shrub Scrub 20.0 0.5 Woody Wetlands 13.6 0.3 ' Developed Low Intensity 6.2 0.1 Totals 4,342.0 100 4.2 Channel Classification Based on the data collected in the field by both survey crews, the channel has a Rosgen Stream Type Classification of C4. 4.3 Discharge (bankfull, trends) The reference bankfull discharge, estimated from the N.C. Mountain Regional Curve is 1 approximately 425 cfs, and estimated from the N.C. Piedmont Regional Curve is approximately 300 cfs. The NRCS survey discharge estimate using Mannings Equation is approximately 375 cfs. The very high percentage of forest land cover in the watershed (98%) serves to stabilize and maintain bankfull discharge quantities, which in theory should remain unchanged unless the developed area within the watershed increases, generating more stormwater runoff that reaches the channel. 4.4 Channel Morphology (pattern, dimension, profile) The reference channel has a sinuosity of 1.1, a riffle bankfull cross-sectional area of 57 square feet and an average slope of 0.014 (see Table 4). . 4.5 Vegetation The forest canopy is dominated by yellow poplar (Liriodendron tulipifera), white pine, red maple (Ater rubrum), hemlock (Tsuga canadensis) and sycamore (Platanus occidentalis). The understory is dominated by rhododendron and smooth alder along the stream. This community is most closely related to a Rich Cove Forest classification (Schafale and Weakley, 1990). 21 ' S.0 Pro'ect Site Wetlands existin conditions p 7 ~„ ``~ ~ °~ J ~ g ) 5.1 Jurisdictional Wetlands Wetlands on the site were evaluated based on the U.S. Army Corps of Engineers 1987 Wetland ' Delineation Manual. The presence or absence of three wetland parameters was documented (hydric soils, hydrophytic vegetation and wetland hydrology), following the guidance set forth in the Manual. One jurisdictional wetland was delineated on Glade Creek and four jurisdictional wetlands were delineated on the unnamed tributary to Glade Creek (see Figure 4 for map and Appendix 2 for forms). ' The areas of the individual wetlands are as follows: Glade Creek wetlands: Wetland 1-0.17 acres 1 Unnamed Tributary wetlands: Wetland 1-0.009 acres Wetland 2-0.034 acres Wetland 3-0.033 acres Wetland 4-0.087 acres Total Wetland Area in Easement-0.33 acres These wetland areas will not be disturbed, they will be preserved with the proposed project. 5.2 Soil Characterization As previously noted, the mapping of soils in Alleghany County is currently under revision. The 1973 Soil Survey shows the area where the wetlands occur as Alluvial Land Wet, and does not include a detailed soil color description. However, based on field investigation and soil cores taken throughout the wetlands, the wetland soils present on the project site are Toxaway series soils (Cumulic Humaquepts). This conclusion is based on soil color and texture. The typical horizon description for the Toxaway series is 0-12 inches l OYR 3/1 loam, 12-25 inches l OYR 3/1 loam and 25-32 niches l OYR 4/1 loam. From the wetland delineation soil descriptions, the hydric soils found onsite are typically 7.5 YR or l OYR 2/1 sandy clay loams in the upper 18 inches of the profile, similar to the Toxaway series. 5.3 Plant Community Characterization The wetland areas onsite are individually quite small, and the dominant woody vegetation occupying the wetlands is red maple. The herbaceous layer is often sparse, but where present, common rush (Juncos effusus) is dominant, along with various sedge species. These wetlands most closely resemble the High Elevation Seep community (Schafale and Weakley, 1990). Ci' ~' _ ~ ~ ; ; ; 6.0 Project Site Restoration Plan 6.1 Restoration Project Goals and Objectives The goals of the project are to: • Rapidly stabilize the channel of Glade Creek relative to natural process, • Rapidly stabilize and preserve the channel of the UT relative to natural process, • Restore and rehabilitate channel features and aquatic habitat in Glade Creek and the UT, Rehabilitate the riparian buffer along both streams, Preserve the existing wetlands onsite. These goals will be accomplished by designing and constructing a stable plan, profile and dimension for the stream channels and re-establishing continuous riparian buffers along the banks. Project implementation will greatly reduce bank erosion and consequently decrease the amount of sediment load in the stream at flows above baseflow. Restoration level (Rosgen Priority Level II) design is needed on all but 125 feet of the channel on the project, due to unstable channel geometry, sinuosity and streambank steepness. Structures will be used to enhance holding and feeding areas for trout. Riparian buffer vegetation will be established to provide food and cover for terrestrial fauna and to provide a carbon source and shade for aquatic habitat. ' To meet the goals listed above, the proposed objectives for Glade Creek are to perform Restoration on approximately 2,430 linear feet (LF) and stabilize 125 LF with Enhancement I design. Please note that a 25-foot section of channel underneath the existing bridge was excluded from the proposed restoration ' total, although chamlel profile and dimension will be altered. The proposed objectives for the UT are to perform Restoration on approximately 275 LF and Preserve 570 LF. All the wetlands onsite will be preserved with the proposed project (see Table 1). 6.1.1 Designed Channel Classification The designed channel classification, based on the existing channel substrate (DSO=12.5 mm) and the designed channel average slope (0.004), entrenchment ratio (>2.2), width/depth ratio (>12) and sinuosity (>1.2) is a Rosgen C4. 6.1.2 Designed Channel Structures In order to provide stabilization to the newly graded channel, especially along outside meander banks, in-stream structures such as log vanes, rootwads, and large woody debris bundles will be utilized. The realignment of the channel will necessitate the removal of some trees (although the alignment was selected to minimize disturbance to mature trees) and this material will be utilized in these structures. Because this restoration is utilizing natural channel techniques and because there are very few man-made constraints on this project, we prefer to use wood structures rather than rock for bank stabilization. The logs used in these structures have a life expectancy of about 20 years which is plenty of time to establish native, riparian trees and shrubs to provide bank stabilization. Rock structures such as cross vanes and steps will be utilized to provide grade control and to quickly bring raised thalwegs down to meet existing elevations. 6.1.3 Target Buffer Communities The site is located in a stream valley at an elevation of approximately 2,600 feet above mean sea level. This location can be characterized as transitional between relatively low elevation vegetation communities and high elevation communities. Accordingly, the stream buffer planting schedule (see Section l 1, Table 6) incorporates species from several vegetation communities 1 1 described by Shafale and Weakley in the draft Fourth Approximation of the Classification of the Natural Communities of North Carolina. Those communities include Northern Hardwood Forest (Typic and Rich Subtype) and the Rich Cove Forest (Montane Intermediate Subtype). Two notable exceptions are the common occurrence of black willow and smooth alder along the existing channel, and their inclusion in the proposed planting schedule, and the absence of those two species from the Shafale and Weakley descriptions. 6.2 Sediment Transport Analysis 6.2.1 Methodology For use as a guideline for sizing the substrate in the proposed restoration channel, a sediment competency analysis was undertaken, using shear stresses computed for the channel. The competency analysis provides an estimate of the local ability of the channel to move sediment for a given discharge and is embodied by estimating the local threshold grain size. For many engineering applications the threshold of sediment motion for an unisize or unimodal sediment can be characterized with the Shields criteria: z~ = z ~ 0.045 (s-1)pgD wherein is the dimensionless critical Shields parameter (in this case assumed to be approximately 0.045), z' is the grain stress (that component of the total boundary shear stress that ' acts upon the sediment grains populating the channel bed surface), s is the specific gravity of sediment (2.65), p is the density of water (1000 kg/m3), g is the gravitational acceleration constant (9.81 m/s"'), and D is the median grain size of an unimodal sediment or the grain size of an unisize sediment (in meters when adopting the above values for the other parameters). When rearranged to solve for the critical grain size, the above equation is transformed to: 1 D = T ~ 1.37z' (s -1)Pgz~~ where D is now in units of millimeters and z' is expressed in Pascals (N/mZ). To estimate the threshold grain size for any location within the project reach, the total boundary shear stress acting on the channel was computed and then decomposed into the grain stress. For steady, uniforn flow the local total boundary stress is provided by the depth-slope product: z ~, = PgRh S where zo is the total channel bom~dary shear stress, p and g are as defined before, Rh is the hydraulic radius, and S is the channel slope. In addition, the Manning's Equation holds for steady uniform flow: U=CRh~S~ n where Uis the mean channel velocity, C is a dimensioning coefficient (1.0 for SI units, 1.49 for Imperial units), and n, Rh, S and are as defined before. By using the Strickler Equation, a Manning's n-value attributable to the sediment roughness can be estimated: n„ = 0.013D 6 where n~ is the Manning's n-value and D is the sediment grain size in millimeters. When the above equations are combined, an equation for the stress decomposition can be developed: 24 1 1 z n z' n„ where all terms are as defined earlier. When this equation is folded into the Shields criteria, the following estimate for the threshold grain size is attained: ~ _ 0.00203zo n ~- where all teens are as defined earlier. This equation provides an estimate of the local threshold grain size at each cross-section for a given discharge (or shear stress). 6.2.2 Calculations and Discussion The competency analysis provides an estimate of the local ability of the channel to move sediment for a given discharge and is embodied by estimating the local threshold grain size. The local threshold grain size mobilized at bankfull discharge was computed for Glade Creek and the unnamed tributary for existing and proposed conditions. The list below summarizes the results of the computations. 1 Computed Channel Shear (]bs/ft~) Threshold Diameter (mm) Glade Creek Proposed (riffle) 0.39 10 Existing (riffle) 0.41 11 Unnamed Tributary Proposed (riffle) O.l 7 3 Existing (riffle) 0.52 15 The reader will note that the Glade Creek proposed conditions are very similar to the existing conditions. This is because there was one riffle located on the restoration reach that, compared to the rest of the restoration reach, was stable, based on the data and field evidence. Data from this stable cross section were used to compute existing shear and particle threshold diameter. Shear stresses and particle threshold diameters in the remainder of the restoration reach are higher in the meanders and much lower in the F/G channel sections. After numerous field reviews of the unnamed tributary chamlel, it was determined to be in a dynamic state and design parameters for restoration of the downstream end of the reach should allow for higher flows to access the floodplain more readily, thus reducing shear stress and particle sized threshold. Therefore, the shear stress and threshold diameter for the proposed channel are lower than existing. 25 ' 6.3 HEC-RAS Analysis 6.3.1 No-rise, LOMR, CLOMR As of July 2, 2007, there is no FEMA mapping for the project area, based on a review of the N.C. Flood maps website. The proposed project is a Rosgen Priority II stream restoration project, with ' no wetland restoration component, only wetland preservation. The hydrology of the site will not be significantly altered by the project. The Faw's property and the adjoining properties will not be hydrologically trespassed upon by the stream restoration project. i f ons or HEC-RAS (USAGE, 2001) was used to model water surface elevations for existing condit a variety of discharges generated from TR-20. The peak l -, 2-, 10-, and 100-year stone discharges were all modeled in HEC-RAS. An existing conditions topographic basemap for the project reach was constructed in ArcGIS by merging the 1-foot contour interval channel survey conducted by Cavanaugh and Associates, PA ' with the 10-foot contour interval Alleghany County map. For existing conditions, topographic information from the Cavanaugh survey superseded that of the County basemap. These basemaps were then used in HEC-GeoRAS (version 3.1) to define and assemble the channel network topology, cross-sections, and reach lengths. Cross-sections were located at hydraulic control points (such as upstream and downstream of bridge culverts and at slope breaks), as well as at intermediate locations to capture changes to channel and overbank geometry. The cross- ' sections were oriented to be orthogonal to, the local mean channel flow and anticipated overbank flow. Bridge and culvert geometry and hydraulic coefficients for the bridge were measured in the field during a site visit conducted in the Spring of 2007. The site visit also provided information on existing channel conditions and overbank vegetation so that the channel and overbank Manning's n-values could be estimated using a table of typical values found in Chow (1959). ' In the absence of paired discharge-stage flow measurements on Glade Creek, model boundary conditions had to be assumed to be uniform flow with bed slopes estimated from the topographic basemaps. A subcritical flow regime was modeled, as there were no significant areas that would warrant calculations under mixed or supercritical conditions. Because of limited detailed survey data beyond the reach extents, boundary conditions were calculated by assuming that a local slope at the top and the slope from the downstream end of the bridge to the bottom of the reach extended beyond the reach. 6.4 Soil Restoration ' 6.6.1 Topsoil Salvage, Soil Testing and Nutrient Amendments Where grading is performed for channel stabilization, the overlying 4-6 inches of topsoil will be stockpiled for redistribution over the site after grading is complete. Soil samples were collected onsite and were sent to the N.C. Department of Agriculture Soils Laboratory for analysis. The analysis report confirms the field assessment of the alluvial soils that occupy the project site, that they are loamy with a moderate to ]ow bulk density and they will not require any more fertilization or lime application than is usually applied for tree seedling and live stake establishment. 26 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 i 1 1 1 6. S Natural Plant Community Restoration 6.5.1 Narrative & Plant Community Restoration The project site is approximately 2,600 feet above seal level, in the Blue Ridge Mountains. The planting schedule for riparian plantings (see Section 11, Table 6) reflects both the Piedmont/Mountain Levee Forest (Shafale and Weakley 1990) and the species already present on site. The trees, mid-story trees and shrubs species listed for Zone 1, Riparian Woodlands-Mesic are all common to the area and easily observed nearby. Many of the species are good food sources for wildlife and are adapted to the more well-drained areas of the site. The Zone 2- Floodplain Bench planting schedule lists a variety of willows, to be planted as live stakes to establish root systems quickly, stabilizing the soil in the active channel. Tag or smooth alder and river birch are listed as sub-canopy and canopy species, respectively. These species will grow taller than the willows and provide additional shading of the channel over the long term. 6.5.2 On-site Invasive Species Management Multiflora rose is the only vegetative invasive species observed onsite, and it occurs mainly on the downstream end of the project. Mechanical control and herbicide will be used to control this species. 27 ' 7.0 Performance Criteria ' All performance criteria for this project are taken directly from the Apri12003 Stream Mitigation Guidelines, as adopted by the USACE, EPA, NCWRC and NCDWQ, Monitoring Level 1. ' 7.1 Streams Upon completion of the project, an as-built survey will be conducted, to document the dimension, ' pattern and profile of the restored channel. Permanent cross sections will be established with an approximate frequency of one per 20 bankfull-width lengths. The as-built survey will include photo documentation at all cross sections and structures, a plan view diagram, a longitudinal profile, vegetation information and a pebble count for at least 6 cross sections. The stream will be resurveyed each year and the survey data compared to the previous year. Success is defined as the documentation of no substantial aggradation or degradation of the channel or banks. Downcutting, deposition, bank erosion and an increase in sands or finer substrate material must be documented for assessment by the regulatory agencies. 7.2 Vegetation Plant survival will be documented with survival plots and photographs. A minimum of 320 stems per ' acre must be surviving after year 3, 288 stems per acre after year 4 and 260 stems per acre after five years of monitoring. 7.3 Schedule /Reporting Monitoring will be performed each year for 5 years with no less than 2 bankfull events documented throughout the period. If less than 2 bankfull events occur, then monitoring will continue until the second bankfull event is documented. The bankfull events must occur during separate years. In the event that the bankfull events do not occur during the five year period, the USACE and NCDWQ, in ' consultation with the resource agencies, may determine that further monitoring is not necessary. The CVS-EEP Protocol for Recording Vegetation (Lee, 2007) will be used to document and track vegetation survival and growth. 1 8.0 References ' Barnes, H.H. Jr., 1967.
