The project streams consist of Byrds Creek, a third order stream, as well as three unnamed first and second order tributaries to Byrds Creek (South Branch, Southeast Branch, and West Branch). The project provides 5,371 stream mitigation units (SMU's). At the downstream limits of the project, the drainage area is 2,957 acres (4.62 square miles). The Byrds Creek Mitigation Site, hereafter referred to as the Site, is approximately 1.8 miles south of Hurdle Mills, NC off of Wolfe Road in southwestern Person County (Figure 1). The Site is located in the Carolina Slate Belt of the Piedmont Physiographic Province (USGS, 1998). The Site is within the South Flat River watershed, North Carolina Division of Water Resources (NCDWR) Subbasin 03-04-01 of the Neuse River Basin and United States Geological Survey (USGS) Hydrologic Unit Code (HUC) 03020201010020. Land use within the watershed is rural and is dominated by forestry, agriculture, and livestock operations; with approximately 60% of the watershed used for agriculture and 40% forested. The Site is located in an active cattle pasture surrounded by wooded lots, small agricultural operations, and rural residential areas. Prior to construction activities, the streams on the Site were heavily impacted by cattle, which led to stream bank erosion and instability. The following project goals were established to address the effects from watershed and project site stressors: • Reduce nutrient loads within the watershed and to downstream waters; • Stabilize eroding stream banks greatly reducing sediment loads; • Restore riffle/pool sequencing resulting in decreased water temperatures and increased dissolved oxygen concentrations; • Establish in -stream structures to improve habitat diversity and trap detritus; • Restore native vegetation and riparian buffers; and • Protect the restored land in perpetuity through a conservation easement. These goals were achieved by restoring 3,096 LF of perennial and intermittent stream channel and enhancing 4,232 LF of perennial stream channel. Restoration and enhancement construction and planting efforts were completed in December 2013. A conservation easement is in place on 24.4 acres of riparian corridor and stream resources to protect them in perpetuity. Monitoring Year 4 (MY -4) monitoring and site visits were completed between the months of January and October 2017 to assess the conditions of the Site. All streams within the Site are stable and functioning as designed. Repair work was performed on sections of Byrds Creek Reach 3 during the spring of 2017. Overall, these isolated sections totaled approximately 200 liner feet in length. The Site's overall average planted stem density of 520 stems per acre is greater than the success criteria of 260 stems per acre density required for MY -5. Hydrologic monitoring gages documented bankfull events for all streams on the Site. All streams have met the MY -5 hydrology success criteria.

The project site is located south of Hurdle Mills off of Wolfe Road and is in the Carolina Slate Belt of the Piedmont Physiographic Province (USGS, 1998). The Multi -Resolution Land Characteristics Consortium (MRLC, 2001) classified approximately 57% of the land in the project watershed as managed herbaceous cover or agricultural, 42% is classified as forested/scrubland, and the remaining 1% is open water. The drainage area for the Byrds Creek Site is 2,957 acres (4.62 square miles). The project stream reaches consist of Byrds Creek reach 2 (BC2), Byrds Creek reach 3 (130), South branch (S131), Southeast branch reach 1 (SEI), and Southeast branch reach 2 (SE2) which are stream restoration and/or enhancement level I approach. The project also consists of Byrds Creek reach 1 (BC1), Byrds Creek reach 4 (BC4), and West branch (WB1) which are enhancement level 11 approach. Mitigation work within the Site included restoring and enhancing 7,328 linear feet of perennial and intermittent stream channel. The stream areas were also planted with native vegetation to improve habitat and protect water quality. The project provides 5,371 stream mitigation units (SMU's). The final mitigation plan was submitted and accepted by DMS in January 2013. Construction activities were completed by North State Environmental in September 2013 and planting and seeding activities were completed by Bruton Natural Systems, Inc. in December 2013. Baseline monitoring (MY -0) was conducted between September 2013 and January 2014. Annual monitoring will be conducted for five years with the close- out anticipated to commence in 2019 given the success criteria are met. Appendix 1 provides more detailed project activity, history, contact information, and watershed/site background information for this project. Three separate conservation easements have been recorded and are in place along the riparian corridors and stream resources to protect them in perpetuity. Directions and a map of the Site are provided in Figure 1 and project components are illustrated for the Site in Figure 2. 1.1 Project Goals and Objectives Prior to construction activities, the streams on the Byrds Creek Site were heavily impacted by cattle, which led to stream bank erosion and instability. Related degradation included declining aquatic habitat, loss of forest, degraded riparian buffers, and water quality problems related to increased sediment and nutrient loadings. Tables 10a -c in Appendix 4 present the pre -restoration conditions in detail. The Site was designed to meet the over -arching goals as described in the mitigation plan (Wildlands, 2013). The project is intended to provide numerous ecological benefits within the Neuse River Basin. While many of these benefits are limited to the Site, others, such as pollutant removal and improved aquatic and terrestrial habitat, have more far-reaching effects. The following project specific goals established in the mitigation plan included: • Reduce nutrient loads within the watershed and to downstream waters; • Stabilize eroding stream banks greatly reducing sediment loads; • Restore riffle/pool sequencing resulting in decreased water temperatures and increased dissolved oxygen concentrations; • Establish in -stream structures to improve habitat diversity and trap detritus; • Restore native vegetation and riparian buffers; and • Protect the restored land in perpetuity through a conservation easement. The design features of this project were developed to achieve multiple project objectives. The stream restoration reaches were designed to frequently flood the reconnected floodplain. This design approach provides more frequent dissipation of energy from higher flows (bankfull and above) to improve channel Byrds Creek Mitigation Site 41100 Monitoring Year 4 Annual Report — FINAL 1-1 stability; provide water quality treatment through detention, settling, and biological removal of pollutants; and restore a more natural hydrologic regime. The project objectives defined in the mitigation plan (Wildlands, 2013) are as follows: • On-site nutrient inputs will be decreased by removing cattle from streams and filtering on-site runoff through buffer zones. Off-site nutrient input will be absorbed on-site by filtering flood flows through restored floodplain areas, where flood flow will spread through native vegetation. Vegetation is expected to uptake excess nutrients. • Stream bank erosion which contributes sediment load to the creek will be greatly reduced in the project area. Eroding stream banks will be stabilized using bioengineering, natural channel design techniques, and grading to reduce bank angles and bank height. Storm flow containing grit and fine sediment will be filtered through restored floodplain areas, where flow will spread through native vegetation. Spreading flood flows will also reduce velocity and allow sediment to settle out. Sediment transport capacity of restored reaches will be improved so that capacity balances more closely to load. Sediment load reduction will be monitored through assessing bank stability with cross section and profile surveys and visual assessment through photo documentation which serves as an accepted surrogate for direct turbidity measurements. • Restored riffle/pool sequences will promote aeration of water and create deep water zones, helping to lower water temperature. Establishment and maintenance of riparian buffers will create long-term shading of the channel flow to minimize thermal heating. Lower water temperatures will help maintain dissolved oxygen concentrations. • In -stream structures will be constructed to improve habitat diversity and trap detritus. Wood habitat structures will be included in the stream as part of the restoration design. Such structures may include log drops and rock structures that incorporate woody debris. • Adjacent buffer and riparian habitats will be restored with native vegetation as part of the project. Native vegetation will provide cover and food for terrestrial creatures. Native plant species will be planted and invasive species will be treated. Eroding and unstable areas will also be stabilized with vegetation as part of this project. • The restored land will be protected in perpetuity through a conservation easement. The design streams were restored to the appropriate type based on the surrounding landscape, climate, and natural vegetation communities but also with strong consideration to existing watershed conditions and trajectory. The designs were developed to correct incision and lack of pattern caused by channelization, bank instability caused by erosion and livestock access, lack of vegetation in riparian zones, and lack of riparian and aquatic habitat. 1.2 Monitoring Year 4 Data Assessment Annual monitoring and site visits were conducted during MY -4 to assess the condition of the project. The stream success criteria for the Site follows the approved success criteria presented in the Byrds Creek Mitigation Plan (Wildlands, 2013). 1.2.1 Vegetative Assessment A total of 14 vegetation plots were established within the project easement area during the baseline monitoring. Thirteen of the plots were established as standard 10 meter by 10 meter plots with one plot established as a 5 meter by 20 meter plot. The final vegetative success criteria will be the survival of 260 planted stems per acre in the riparian corridor along restored and enhanced reaches at the end of MY -5. The MY -4 vegetative survey was completed in August 2017. The 2017 annual vegetation monitoring resulted in an average planted stem density of 520 stems per acre, which is greater than the Byrds Creek Mitigation Site Monitoring Year 4 Annual Report — FINAL 1-2 requirement of 260 stems per acre. All 14 vegetation plots met success criteria during MY -4. The MY -4 planted stem density is approximately 30% less than the baseline density recorded (734 stems per acre) in January 2014. There is an average of 12 stems per plot and all plots are on track to meet the success criteria required for MY -5. Refer to Appendix 2 for vegetation plot photographs and the vegetation condition assessment table and Appendix 3 for vegetation data tables. 1.2.2 Vegetation Areas of Concern During a site visit in December 2017 it was discovered that an area of the easement, approximately 0.46 acres, along Byrds Creek Reach 4 had been mowed. After a discussion with the landowner it was determined that he had allowed a family member to hunt his property. This family member mowed shooting lanes into the easement. The landowner has talked to this family member and assured Wildlands this will not happen again. The property owner is working with Wildlands to fix this issue. Wildlands will replant this area with trees of a similar age and size to the ones that were mowed. Refer to the CCPV Map in Appendix 2 for the areas of easement encroachment and Table 6 for acreages. 1.2.3 Stream Assessment Morphological surveys for MY -4 were conducted in May 2017. All streams within the Site are stable with little to no erosion and have met the success criteria for MY -4. Refer to Appendix 2 for the visual assessment table, integrated current condition plan view (CCPV) map (Figure 3), and reference photographs. Refer to Appendix 4 for the morphological data and plots. While there have been some minor post -construction adjustments within the restored channels; the cross sections show little to no change in the bankfull area, maximum depth ratio, or width -to -depth ratio. Surveyed riffle cross sections fell within the parameters defined for channels of the appropriate Rosgen stream type. The surveyed longitudinal profile data for BC2, BC3, S131, SE1, SE2a and SE2b illustrates that the bedform features are maintaining lateral and vertical stability. The riffles are remaining steeper and shallower than the pools, while the pools are remaining deeper than the riffles and maintaining flat water surface slopes. The longitudinal profiles show that the bank height ratios remain at or very near to 1.0 for the restoration reaches. Entrenchment ratios vary slightly from year to year due to minor changes in bankfull widths. Small adjustments in width occur due to vegetation, sediment deposition, and many other factors. These minor changes do not indicate channel instability. Pattern data will be collected in MY -5 only if there are indicators from the profile or dimensions that indicate significant geomorphic adjustments have occurred. No changes were observed during MY -4 that indicate a change in the radius of curvature or channel belt width. Several beaver dams and a lodge were discovered in January 2017 (MY -4). All dams were on Byrds Creek reach three, with the largest dam at approximately station 42+50. This beaver dam extended onto the floodplain which caused water to flow out of the channel and onto the floodplain. Water was impounded up to the culverts at the easement break near station 35+00. The USDA was contracted in February 2017 to trap beaver and breach the dams at the Site. By the end of February 2017 seven beaver had been trapped and all beaver dams were breached. Once water levels were back to baseflow, Land Mechanics Designs, Inc. was hired to repair the damage associated with the beaver impoundments. During repair work one large beaver dam, and three smaller dams (stations 36+00, 38+50, and 46+50) were removed. Stream banks damaged as a result of the dams were graded, seeded, and matted. Near station 42+75 rilling and minor bank erosion had occurred from overland flow as a result of the large beaver dam. Sod mats were added to this area to stabilize stream banks. The left stream bank near station 46+50 had eroded around a small beaver dam. This area was stabilized using Byrds Creek Mitigation Site Monitoring Year 4 Annual Report — FINAL 1-3 brush, cobble, and soil, then the bank was seeded and matted. Live stakes were planted along stream banks as needed to stabilize any repair areas and to replace vegetation removed by beaver activity. 1.2.4 Stream Areas of Concern As of October 2017, beaver activity has not been observed on the Site since the removal in February 2017. Beaver presence and the areas of repair will continue to be monitored in subsequent years. 1.2.5 Hydrology Assessment At the end of the five year monitoring period, two or more bankfull events must have occurred in separate years within the restoration reaches. Bankfull events were recorded on all three gaged streams during the MY -4 data collection. Byrds Creek and South Branch have each had bankfull events during MY -1, MY -2, MY -3, and MY -4. Therefore, they have met the hydrology success criteria for the Site. Southeast Branch recorded bankfull events during MY -2, MY -3, and MY -4, also meeting hydrology success criteria. Refer to Appendix 5 for hydrologic data. 1.2.6 Maintenance Plan No maintenance is required at this time. 1.3 Monitoring Year 4 Summary All streams within the Site are stable and functioning as designed. The average planted stem density for the Site is 520 stems per acre and is on track to meet the MY -5 success criteria. Bankfull events were documented with gages located on all three streams during MY -4. The MY -5 stream hydrology success criteria has been met on Byrds Creek, South Branch, and Southeast Branch. Beaver activity was observed at the beginning of MY -4, but no activity has been detected since repairs were completed in the spring of MY -4. Summary information and data related to the performance of the 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 Mitigation Plan documents available on DMS's website. All raw data supporting the tables and figures in the appendices are available from DMS upon request. Byrds Creek Mitigation Site Monitoring Year 4 Annual Report — FINAL 1-4 Section 2: METHODOLOGY Geomorphic data was collected following the standards outlined in The Stream Channel Reference Site: An Illustrated Guide to Field Techniques (Harrelson et al., 1994) and in the Stream Restoration: A Natural Channel Design Handbook (Doll et al., 2003). Longitudinal and cross-sectional data were collected using a total station and were georeferenced. All CCPV mapping was recorded using a Trimble handheld GPS with sub -meter accuracy and processed using Pathfinder and ArcView. Crest gages were installed in surveyed riffle cross sections and monitored quarterly. Hydrology attainment installation and monitoring methods are in accordance with the USACE (2003) standards. Vegetation monitoring protocols followed the Carolina Vegetation Survey -DMS Level 2 Protocol (Lee et al., 2008). Reporting follows the DMS Monitoring Report Template and Guidance Version 1.3 (DMS, 2010).
