The site encompasses approximately 47 acres of former cattle pasture, crop land and riparian forest along Little Buffalo Creek and portions of seven unnamed tributaries (Figures 1 and 2). Little Buffalo Creek is located within the Yadkin River Basin (03040105; 03040105020060). Historic land use at the site had consisted primarily of ranching activities that had allowed cattle access to the stream and riparian zone. Several reaches of the stream have bedrock in their streambed and vertical migration of the stream has been confined to a small percentage of the project site. 1.2 Project Goals and Objectives The goals of the Little Buffalo Creek Stream Restoration project include, but are not limited to, the enhancement of water quality and aquatic/terrestrial habitat, stream stability improvement, and erosion reduction. The uplift of these stream functions specifically requires: • Protecting and improving water quality through the removal or minimization of the biological, chemical, and physical stressors: o Reducing sediment input into the stream from erosion; o Reducing non -point pollutant impacts by removing livestock access (including restoring forested buffer; o Protecting headwater springs. • Improving aquatic and terrestrial wildlife habitat: o Moderating stream water temperatures by improving canopy coverage over the channel; o Restoring, enhancing, reconnecting, and protecting valuable wildlife habitat. • Restore floodplain connectivity: o Reestablishing floodplain connection thereby dissipating energy associated with flood flows. In addition to the ecological uplift that the project will provide to the Site through the improvement of the stream functions, this project establishes the following environmentally advantageous goals: • Providing a water source for livestock removed from the stream and riparian corridor; • Reducing the number of locations that livestock are able to cross the stream; • Providing a safe and environmentally appropriate stream crossing point for livestock. In order to achieve the project goals, Berger proposes to accomplish the following objectives: • Fence the cattle out of the stream and riparian corridor; • Remove invasive vegetative species from the riparian corridor; • Restore and enhance unstable portions of the stream; • Preserve the stream channel and banks through a conservation easement; • Plant the riparian corridor with native tree and shrub vegetation. The expected ecological benefits and goals associated with the Little Buffalo Creek site mitigation plan serve to meet objectives consistent with the resource protection objectives detailed in the Yadkin -Pee Dee River Basinwide Water Quality Plan, 2008. Little Buffalo Creek Stream Mitigation Project — Project #94147 — Louis Berger — March 2017 — Monitoring Year 2 — Final 1.3 Project Success Criteria Streams For stream hydrology, a minimum of two bankfull events must be documented within the standard 5 -year monitoring period. In order for the monitoring to be considered complete, the two verification events must occur in separate monitoring years. All of the morphologic and channel stability parameters will be evaluated in the context of hydrologic events to which the system is exposed. Dimension — General maintenance of a stable cross-section and hydrologic access to the floodplain features over the course of the monitoring period will generally represent success in dimensional stability. For stream dimension, cross-sectional overlays and key parameters such as cross-sectional area, and the channel's width to depth ratios should demonstrate relative stability in order to be deemed successful. Pattern — Pattern features should show little adjustment over the standard 5 year monitoring period. Rates of lateral migration need to be moderate. Profile — For the channels' profile, the reach under assessment should not demonstrate any trends in thalweg aggradation or degradation over any significant continuous portion of its length. Over the monitoring period, the profile should also demonstrate the maintenance or development of bedform (facets) more in keeping with reference level diversity and distributions for the stream type in question. It should also provide a meaningful contrast in terms of bedform diversity against the pre-existing condition. Bedform distributions, riffle/pool lengths and slopes will vary, but should do so with maintenance around design distributions. This requires that the majority of pools are maintained at greater depths with lower water surface slopes and riffles are shallow with greater water surface slopes. Substrate and Sediment Transport — Substrate measurements should indicate progression towards, or maintenance of the known distributions from the design phase. Sediment Transport should be deemed successful in by absence of any significant trend in the aggradation or depositional potential of the channel. Vegetation Survival of woody species planted at mitigation sites should be at least 320 stems/acre through year three. A 10 percent mortality rate will be accepted in year four (288 stems/acre) and another 10 percent in year five resulting in a required survival rate of 260 trees/acre through year five. This is consistent with Wilmington District (1993) guidance for wetland mitigation (USACE 2003). 1.4 Mitigation Components and Design The Little Buffalo Creek Site consists of six reaches along the mainstem and seven unnamed tributaries (UTs). The mainstem of Little Buffalo Creek as well as UT 4 and UT 7 are perennial streams. The remainders of the UTs are intermittent streams associated with groundwater seeps. This stream mitigation project includes reaches of restoration, enhancement, and preservation along the mainstem and the associated UTs. In total, the Site will provide 13,362 linear feet of restoration, enhancement, and preservation (Tables 1 & 4). A summary of restoration and enhancement activity and reporting history can be found in Table 2. Restoration activities have established a new, stable stream channel with the appropriate dimension, pattern and profile to transport perennial flow and sediment and have re -connected the stream to its floodplain. Reestablishment of native riparian forest vegetation and installation of cattle exclusion fencing were also performed as part of the restoration activities. Enhancement activities included reestablishing native riparian vegetation within a 50 -foot easement along each bank of the stream corridor and excluding cattle with fencing. In the case of enhancement level I the activities included reshaping or relocating the bed and Little Buffalo Creek Stream Mitigation Project — Project #94147 — Louis Berger — March 2017 — Monitoring Year 2 — Final banks and riparian forest planting. Preservation was conducted within portions of the stream corridors that have intact riparian forests and stable stream reaches and included excluding cattle with fencing. At a 1:1 ratio for restoration, 1.5:1 for enhancement level I, 2.5:1 for enhancement level Il, and a 5:1 ratio for preservation, the DMS will receive, as of January 2017, approximately 6,411 stream mitigation units from the Site (Table 1). In addition, approximately 47 acres of riparian buffer have been protected within a conservation easement. This stream credit generation has the potential to increase to 6,450 stream mitigation units as a result of additional enhancement level I work conducted in the fall of 2016 within a portion of UT3. This area, previously assessed as enhancement level II, had additional entrenched portions of the tributary graded to re -connect the channel with its floodplain and the riparian zone replanted. 1.5 Monitoring Year 2 Conditions Assessment 1.5.1 Vegetation Assessment In Year 2 of monitoring, four vegetation monitoring plots are exceeding requirements by 10% (436 to 823 stems/acre), two vegetation monitoring plots are exceeding requirements by less than 10% (each 339 stems/acre), two vegetation monitoring plots fail to meet requirements by less than 10% (each 290 stems/acre), and four vegetation monitoring plots are failing to meet requirements by over 10% (97 to 242 stems/acre). Recruitment of native plant seedlings was recorded in 11 of 12 monitoring plots (Tables 6, 7, 8, and 9). The current average estimate of 395 planted stems per acre for the site is exceeding the required success criteria of 320 stems per acre. Uplift in previously poor performing areas is due to the additional planting of approximately 3,000 trees within 7 riparian areas covering 7.6 acres that took place in February 2016. Any deficiencies are primarily associated with the areas around the six monitoring plots failing to meet requirements. The likely cause of the poor performance in these areas, as well as lower than expected survival in some replanted areas, is due mostly to an incident where a herd of cattle were allowed back into the easement for an extended period of time. The intruding cattle grazed some of the planted stems and trampled a small number of them as well. Additional planting of approximately 3,500 trees within 9 riparian areas covering approximately 8.5 acres will take place in March 2017. Tree establishment and survival will continue to be monitored. Significant growth was observed in planted American sycamore (Platanus occidentalis), green ash (Fraxinus pennsylvanica), hazel alder (Alnus serrulata), and black willow (Salix nigra) trees. This is most likely due to more normal precipitation levels in 2016 (NOAA Historical Palmer Drought Indices) and less grazing by cattle on these specific plant species. Tree establishment and survival will continue to be monitored. Black willow and silky dogwood (Cornus amomum) live stakes throughout the restoration areas are doing well and very few have been observed to be dead. Surviving stakes are growing quickly and are already contributing to bank stability. Soft rush (Juncus effusus) has become established on parts of the stream bank and is adding additional stability to sections of UT7 and UT3. Additional stability is being provided by grasses and sedges that have become established on banks throughout the site. Volunteer crop cover is no longer present and has been outcompeted by other species such as goldenrods (Solidago), asters (Aster), jimsonweed (Datura), and native grasses. Previously there were areas within the riparian buffer that were having low success in establishing herbaceous vegetation cover due to drought and sections of bank scour. These areas included approximately 300 feet along the mainstem of Reach 1, approximately 130 feet along the mainstem of Reach 4, and approximately 530 feet of UT 3. These problem areas were reseeded with annual ryegrass and native forbs in February 2016. Reseeded areas total approximately 1.8 acres and make up 53% of E1 areas and 20% of restoration areas. Little Buffalo Creek Stream Mitigation Project — Project #94147 — Louis Berger — March 2017 — Monitoring Year 2 — Final The herbaceous cover in the 300 foot length of Reach 1 has improved since reseeding. The herbaceous cover in the 130 foot section along the mainstem of reach 4 has improved slightly since reseeding, and the herbaceous cover in the 530 foot section of UT3 is somewhat improved though sections have been affected by scour and cattle grazing. Despite a period of cattle intrusion, overall herbaceous cover throughout the site has greatly increased. This is most likely the result of more normal precipitation levels following a drought year (NOAA Historical Palmer Drought Indices). Additional native grass and forb seeding will be performed in the spring of 2017 to address any remaining areas with poor herbaceous cover establishment. Past treatment and removal of privet (Ligustrum), multiflora rose (Rosa multiflora), and tree -of -heaven (Ailanthus altissima) from riparian areas has been mostly successful, though a few problem areas remain and follow up treatment will be performed. Through site inspections, tree -of -heaven is still established at the upstream ends of both UT 2 (approx. 45 Oft) and UT 7 (approx. 400ft), as well as four large trees between UT4 and UT3 (Figure 2). The larger trees at UT7 have been treated with herbicide and at time of monitoring were either dead or dying. However, they still produced seeds or root sprouts and will require further control. The UT 2 area was treated but will require further treatment as well. Privet continues to be present in various areas throughout the site, particularly on the upper portion of UT2 and the lower portion of UT7. Privet and tree -of -heaven were removed by hand from areas along UT 7 and UT 2 in February of 2016. During the Year 2 monitoring event in September of 2016 tree -of -heaven and princess tree were removed by hand from areas along UT 7, UT 2, Reach 3, and Reach 1. Both privet and tree -of -heaven will be treated with herbicide application again in spring of 2017 in accordance with NC Department of Agriculture (NCDA) rules and regulations. 1.5.2 Stream Assessment For most of the site there has been very little change from the Year 1 monitoring survey completed in September 2015 in regards to stream stability and conditions. The primary issue identified in Year 2 monitoring has been damage to multiple reaches and tributaries due to the intrusion by cattle. UT2 and UT3, as smaller tributaries with soft clay soils, took the most observable damage. Cattle crossing and grazing within the inner channel of the lower stem of UT2, near the confluence of Little Buffalo Creek, and all of UT3 enhancement level I and restoration work, has formed areas with deep divots. Despite this damage, the tops of banks remain stable and in good condition. Based on the soil types of these tributaries and sediment load, it is believed that the damage can be reversed naturally through a significant flow events that will re -deposit sediment within the depressions in the channel. UT4 and Reach 3 and 4 of Little Buffalo Creek all showed minor damage to the channels due to cattle, and all in isolated spots of each segment. With the exception of Reach 3, it is believed all damage can be reversed naturally through a significant storm event. During the spring 2017 maintenance work, the damaged areas will be re-evaluated to determine if signs of recovery area present, such as recent deposition. If it is evident that the stream segments cannot recover in a short period without intervention, action will be taken to fix the sections accordingly. In early winter 2016, DENR representatives conducted a site visit to observe site conditions following a significant flow event. As part of this visit, a segment of UT3 was identified with a severe entrenchment and headcut in a portion of enhancement level II. Additionally, the restoration section in Reach 3 showed aggradation in both the riffle and pool sections connecting the restored channel to the existing channel at the upstream and downstream connection points. In spring of 2016, Louis Berger staff observed signs of an overflow chute forming in the Reach 3 restoration section as a result of the aggradation and high backwater caused at the upstream connection to the existing channel. As part of the September 2016 maintenance and monitoring work, the aggradation was removed on both the upstream and downstream connections of the restoration portion of Reach 3. The material removed was placed on the left bank to fill in the overflow chute, and the more extreme backwater condition immediately upstream of the site work was reduced to a more suitable level. This work simultaneously patched the minor cattle damage caused in the Reach 3 work area. Additionally, the entrenched banks identified in a portion Little Buffalo Creek Stream Mitigation Project — Project #94147 — Louis Berger — March 2017 — Monitoring Year 2 — Final of UT3 were graded to remove entrenchment and reconnect the channel to the floodplain and plant the riparian zone. This action is consistent with enhancement level I work, and creates the potential to raise the enhancement level from EIl to EI in this 146 feet reach. A sinuous low flow channel within the areas of restoration in Reach 1, Reach 3 and UT 7 continue to develop as expected. The development of this sinuous channel at base flow conditions is important to providing adequate riffle -pool systems needed at base flow to provide in -stream habitat areas for fish, amphibians, and aquatic insects. In addition, the stream bedload was observed to continue to be sorted and finer material has either moved to the stream bank edges or moved downstream and a courser bed material is present within the channel. However, despite 2016 being a non -drought year, the months of June, July and September were below average rainfall months and stretches of the main channel were dry during the September monitoring. The pebble count recorded a higher percentage of silts deposited during the receding flow. As a result of exceptionally high silt deposits, pebble count surveys were not conducted in the following cross sections during the 2016 monitoring event: UT2-1R, UT34R, UT3-1P, UT3-2R, UT3-3R, and UT7-1P. This is expected to be a temporary condition. In -stream structures have generally maintained their stability and performance within the site, with the exception of the step -pool system on UT 7 near the confluence with the mainstem. Due to the backflow conditions generated in storm events in this area, bed material settlement was observed within the step - pools. This was first identified within the Year 1 monitoring. Larger sediment material has filled the lower two step pools, generating a longer riffle into the confluence of Little Buffalo Creek, and decreased the max depth to mean depth ratio of less than 1.6 for habitat suitability in the upper pools. Although the step pools have filled greater than desired with larger material, they still provide adequate fish passage during low flow events when the channel is not dry. As the intent of the structures is to provide the head drop from the higher floodplain of UT7 to Little Buffalo Creek in a stable manner, while still providing fish passage within the tributary, no action to reshape the pools is proposed. This conclusion is also generated based on the understanding that the larger sediment source comes from immediately upstream of the culverts at Old Mine Road as part of the passage dissipation reinforcement, and that any attempt to remove the larger cobble sediment will likely only result in the pools to refill from the same sediment source supply. In addition to the lower step pools infilling, one rock vane step pool was identified for potential piping in the September 2016 site assessment. As the channel was dry, it could not be verified that the structure is allowing seepage beneath the vane. This will be observed in the Spring 2017 maintenance work and corrective action taken to fix the structure if it indeed is allowing seepage beneath the vane. Future channel maintenance may include chinking of in -stream structures to prevent piping, securing of loose coir matting, and supplemental installations of live stakes and other target vegetation along the channel bank. Areas where storm water and floodplain flows intercept the channel may also require maintenance to prevent bank failures and head- cutting. The stream restoration and enhancement areas are relatively stable and will continue to adjust somewhat in response to storm events. Gage data throughout the site supports four different bankfull events during the Year 2 monitoring period which are supported by observations of rack debris outside of the top of bank and in the floodplain of UT7 and the mainstem. The stream channel is beginning to develop the desired sinuosity and in -stream structures are remaining stable and functioning as designed; the exception being the step - pool system in UT -7 as noted above. No work is planned on these pools as of now but may occur during the 2017 maintenance period if needed. Two groundwater monitoring wells were installed at the top and bottom of UT3 in February of 2016 to provide additional hydrological data to demonstrate groundwater connectivity to the stream channel of UT3. The cross-section and longitudinal profiles were conducted during the dry season, resulting in water Little Buffalo Creek Stream Mitigation Project — Project #94147 — Louis Berger — March 2017 — Monitoring Year 2 — Final surface elevations that were indistinguishable from the thalweg elevations at that time. Distinct water surface elevations are included in the longitudinal profiles where water was flowing within the channel. 1. 5.3 Site Boundary Assessment A number of site boundary issues were discovered during the Year 2 monitoring and maintenance period. A corner of fence where UT 3 joins the mainstem was found to be cut and reassembled, presumably by the land owner to remove escaped cattle. The electric wire of the cattle crossing fence in Reach 5 was broken, likely due to storm debris and flows, and no longer providing an electrical charge. The larger portions of the cattle crossing fence are up and functioning and the gates to the crossing are closed. The fence next to the northwestern gate of the cattle crossing has also been cut and hastily repaired as well as a corner of fence where UT 2 meets the mainstem. These damages are also likely the result of landowners moving cattle into or from the easement. The barbed wire has been broken on a small section of fence along the northeast edge of UT 7, possibly due to a tree fall in that area. The fence at the top of UT 1 has been completely knocked down due to the accumulation of vegetation and log debris from the adjacent fields causing enough force to push it over during a flood event. At a point in between the February and September maintenance work of 2016, unknown persons installed barbed wire and a woven metal fence "flood gate" across the easement along the downstream side of Old Mine Road to close off access to Reach 2. This may have been installed by the landowner with the intention of placing and keeping cattle within the easement. A team of surveyors discovered the cattle in early September and they were removed within days of their first observation. At the time of Year 2 monitoring, four cattle were observed in the easement and were removed the same day. Louis Berger is currently assessing the level and cost of damage and working to identify those responsible. Discussions with the landowner regarding maintenance of the crossing, fencing and encroachments into the easement is ongoing. In the fall of 2016 additional fencing was installed along the mainstem at Old Mine Road to prevent access to the easement at these locations and the barbed wire across Little Buffalo Creek at Old Mine Road has also been removed. All other major fence repairs and the installation of conservation easement boundary signs was also completed in the fall of 2016. Summary information/data related to occurrence of items such as encroachment by landowners or evidence of cattle intrusion and statistics related to performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the As -Built Baseline Monitoring Report and in the Mitigation Plan documents available on NCDEQ's website. All raw data supporting the tables and figures in the appendices is available from NCDEQ upon request. Little Buffalo Creek Stream Mitigation Project — Project #94147 — Louis Berger — March 2017 — Monitoring Year 2 — Final 2.0 Methodology Monitoring for stream stability, stream hydrology, and vegetation will be monitored annually for five years following the initial Baseline and As -Built Report. Annual monitoring requirements are based on the U.S. Army Corps of Engineers Stream Mitigation Guidelines document (USAGE 2003) and supplemental requirements listed in the DMS Stream and Wetland Mitigation Monitoring Guidelines dated February 2014 (NCEEP 2014). Establishment, collection, and summarization of data collected was in accordance with the NCDEQ guidance document EEP Annual Monitoring Report Format, Data Requirements, and Content Guidance (April 2015). 2.1 Geomorphology Surveys for Year 2 monitoring were conducted by Louis Berger in September 2016 using a Trimble M3 Total Station, geo referenced to North Carolina State Plane (NAD83-State Plane Feet-FIPS3200) with vertical datum North American Vertical Datum of 1988 (Feet NAVD88). 2.2 Longitudinal Profiles A total of approximately 2950 feet of channel along 8 longitudinal profiles is being surveyed annually. This includes 335 feet on LBC Reach 1, 225 feet on LBC Reach 3, 112 feet on LBC Reach 4, 51 feet on UT 2, 771 feet on UT 3, 411 feet on UT 4, 977 on UT 7 and 62 feet on UT 8. Data collected from annual monitoring is being compared with the as -built conditions to document the current state of the channel and any trends in the stream profile occurring throughout the monitoring period. The start and finish locations of each cross-section and longitudinal profile are collected using a Total Station. 2.3 Cross Sections & Particle Size Distribution A total of 15 cross-sections, including 9 riffles and 6 pools were installed upon completion of construction and are being monitored annually. Two additional cross-sections were added within the step -pool portion of UT 7 in monitoring Year 2. The total number of cross-sections includes five on the mainstem of Little Buffalo Creek, one on UT 2, four on UT 3, two on UT 4, and five on UT 7. Pebble count surveys were conducted at each cross section. Moving from bank to bank, particles were picked up blindly and at random and measured in millimeters. Enough samples were taken to get a representative sample of particle size distribution for each cross section. Sample size ranged from 50 in pool areas dominated by fines to 100 in flowing riffle areas with a diversity of particle sizes. 2.4 Vegetation Monitoring The CVS -DMS entry tool database was used to calculate the number of monitoring plots needed based on project acreage. Louis Berger established twelve vegetation monitoring plots across all reaches and tributaries of the project area based on guidance given in the CVS -DMS Protocol for Recording Vegetation Version 4.2 (Lee et al. 2008). Each plot measures approximately 0.025 acres individually and is staked out with bright orange painted rebar and marked with two upright sections of PVC pipe. Photos were taken of each plot and Year 2 monitoring data was entered into the CVS -DMS database under the Little Buffalo Creek Stream Mitigation Project (Project ID 94147). Additional PVC markers were added to plot corners during Year 2 in order to make corner stakes easier to find among the increasing herbaceous cover. For a monitoring event, yellow rope is tied around the four corner stakes to mark out the plot. In Year 0, a GPS was used to collect coordinates of each stem and their position was measured in relation to the X and Y axis of the plot. Additionally, each stem was marked with pink flagging to make them easy to locate and identify during the next monitoring event. Flagging is re-applied each year. Planted stems were identified, Little Buffalo Creek Stream Mitigation Project — Project #94147 — Louis Berger — March 2017 — Monitoring Year 2 — Final measured, and given a vigor score ranging from 0 to 4 based on the CVS -DMS database. Naturally recruited stems were identified and tallied only if alive. These stems were not measured or given a vigor score. 2.5 Hydrological Monitoring A total of eight water level gages were installed on site. The gages are being monitored biannually to document highest stage for the monitoring interval and verify occurrences of bankfull and geomorphically significant flow events. In addition, observations of wrack and depositional features in the floodplain, if present, are being documented with photos. In February of 2016 two groundwater monitoring wells were installed at the top and bottom of UT 3 to provide additional hydrological data to demonstrate groundwater connectivity to the stream channel. 2.6 Photo Points & Visual Assessment Permanent photo stations were established at each cross-section to digitally document annual conditions of the left and right banks. Each vegetation monitoring plot includes a photo station taken diagonally from a plot corner towards the opposite plot corner. Additional permanent photo locations have been established throughout the project area and can be found on the CCPV maps in Appendix A. Visual stream assessments are conducted during annual monitoring to summarize performance percentages of morphological and structural features. Visual vegetation assessments are also occurring to catalog the extent and type of vegetation issue areas as compared to the total planted acreage within the project site.

ER and BHR have been addressed in prior submissions as a subsample (cross-sections as part of the design measurements), however, these subsamples have often focused entirely on facilitating design without providing a thorough pre-constrution distribution of these parameters, leaving the reader/consumer with a sample that is weighted heavily on the stable sections of the ranch.
