The objectives of the project were to restore stream stability and improve aquatic habitat, restore riparian buffer along the stream channel, preserve riverine wetlands, establish a wildlife corridor, divert an unbuffered agricultural ditch system from the stream channel to an irrigation pond, and establish native vegetation within the permanent conservation easement. The project included 3,789 linear feet of stream restoration and 329 linear feet of stream enhancement. Priority II stream restoration involved restoring riffle /pool sequences, the installation of structures, and floodplain grading to improve floodplain connectivity and provide diverse instream habitat. Enhancement II stream restoration involved the planting of native hardwood trees and shrubs. Also, native riparian buffer planting took place on over 18 acres of the site, and an additional 1.37 acres of wetland was preserved. The project will result in 3,931 stream mitigation units (SMUs), 17.2 of buffer mitigation units (BMUs), and 0.27 wetland mitigation units (WMUs). The Monitoring Year 4 [MY4] stem counts within each of the nine (9) vegetative monitoring plots are included in Tables 7 and 9 in Appendix C. Located within the Tar- Pamlico River basin, this project was instituted prior to October 11, 2007 and is therefore eligible for riparian buffer restoration credit up to 200 feet from the top of bank of all perennial and intermittent waterways within the conservation easement area. As such, the vegetative monitoring plots have been assessed for the vegetation success criteria for both buffer (320 planted trees /acre) and streams (MY4 interim criteria of 280 woody stems /acre). Eight of the nine vegetative monitoring plots met the vegetation success criteria for riparian buffers, with the exception of VP7. Of the five plots within the 50 -foot stream buffer, four are currently meeting the vegetation success criteria for streams, again the exception is VP7. It should also be noted a supplemental planting took place throughout the project area in November /December 2013. Also, the downstream end of the project was replanted in December 2014. Evidence, mostly minor, of beavers and nutria has been observed within the project limits in 2011, 2012, and 2013. The only exception was during the 2013 annual fall monitoring when a majority of the Riverine Bottomland Hardwood Forest planting zone was inundated as a result of several beaver dams. Following a full growing season the areas affected by the prolonged inundation have rebounded and the stream remains in stable condition. During the MY4 stream survey, livestakes affected by previous beaver activity were showing evidence of resprouting and should continue with excellent vigor. Areas throughout the stream still have approximately 6 -8 inches of fine sediment accumulation. These areas do not appear to be affecting the stability or functionality of the stream, and will be reevaluated during the initial assessment in spring 2015. Areas of Murdannia keisak (marsh dayflower), observed in previous years, are still present in and along the banks of stream throughout Section 1 but have not expanded. Murdannia keisak continues to be most abundant between Station 0 +50 and 1 +50, between Station 3 +50 and 7 +00, near Station 21 +50, and near Station 28 +50. Currently, these areas of Murdannia keisak do not pose a threat to native vegetation establishment or stream stability, but they will continue to be monitored during future field visits to document any changes. Small areas of Mikania scandens (Climbing hempweed) were observed on planted stems in and around vegetative plots 6 and 7 and some isolated sections of livestakes along the Oakley Crossroads (G) Stream and Buffer Restoration (Year 4 of 5) Page I Stantec - 2014 Monitoring Report (EEP# 273) December 2014 stream banks. Persicaria perfoliata (Tearthumb) was also observed in dense colonies throughout the riparian area and on some sections of livestakes. The livestakes will likely be able to out compete both the Mikania scandens and Persicaria perfoliata without the need for removal /treatment. These areas will continue to be monitored as there is potential for the vines to affect planted stems. Additionally, the streambanks on both left and right bank were observed to be bare below the Briley culvert, between Station 38 +25 and 39+00. Overall the planted woody vegetation continues to have excellent vigor and exhibit little to no issues becoming established among the common successional herbaceous species. Sections 1, 2, and 3 of the Oakley restoration project were observed generally to be in stable condition following a year after being flooded by a beaver impoundment for an extended period of time. As a whole the channel's profile and cross - section adjusted only minimally from baseline conditions. However, from approximately Station 5 +00 to 15 +00 the thalweg has aggraded relative to previous years. This is likely a result of the degradation observed from Station 0+00 to 5 +00 where sediment from upstream of the project area as aggraded relative to the baseline thalweg. The stream appears to be transporting the sediment while remaining stable and functioning as designed. The channel has good connection to its floodplain. Evidence of bankfull overflow was observed during the initial assessment in the spring of 2013 an again in November 2014. The dimension, pattern, and profile survey for MY3 conditions for Section 1 and Section 2 are consistent with the design intent to reduce stream power and erosion potential. An area of aggradation, noted in previous years, was again observed below the upstream culvert between Station 0+00 and 6 +00. Only one structure, a log sill at Station 23 +27.75, was observed to be losing grade control, but the area appears to be working toward an equilibrium. The areas of profile adjustment do not currently threaten the stability of the stream. These areas will continue to be monitored during future field visits to document any changes. A few relict nutria burrows were also observed between Station 4 +40 and 10 +00, but the livestakes are maintaining bank stability and these areas do not threaten the stability of the stream. Callitriche heterophylla (water starwort), a non - invasive species, was again observed in several areas along all three sections of the stream. This aquatic plant was also noted to be present in monitoring years 1, 2, and 3 as well as prior to the construction of the restoration project. Neither the nutria nor the water starwort currently threaten the stability of the restored stream. These issues will continue to be monitored during future field visits to document any changes. The permanent pins for Cross- section 6 had been removed and could not be surveyed. The pins wills be reset during the initial assessment of spring 2015. During the 2013 annual monitoring the flooding caused by the beaver activity hindered the visual assessment of the vegetative cover of brush mattresses along the entire stream and therefore was not included in the monitoring report as requested by NCEEP. Areas observed in 2012 where brush mattresses had less than the required 80% vegetative cover have been removed from Figure 2 in Appendix A, as these areas currently exhibit the required 80% vegetative cover and are thriving. The wetland preservation areas were also visually assessed during the vegetation monitoring. No issues were observed in these areas and existing vegetation appears to be in good condition. These areas will continue to be monitored during future field visits. Summary information, data, and statistics related to the 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 mitigation and restoration plan Oakley Crossroads (G) Stream and Buffer Restoration (Year 4 of 5) Page 2 Stantec - 2014 Monitoring Report (EEP4 273) December 2014 documents available on EEP's website. All raw data supporting the tables and figures in the appendices is available from EEP upon request. 2.0 Methodology Channel stability and vegetation survival were monitored on the project site. Post - restoration monitoring will be conducted for a minimum of five years or until the success criteria are met following the completion of construction to document project success. The Monitoring Year 4 survey was completed using survey grade GPS on October 7 and 29, 2014. 2.1 MORPHOLOGICAL PARAMETERS AND CHANNEL STABILITY 2.1.1 Dimension Dimensional characteristics were monitored at 7 permanent cross - sections (4 riffles, 3 pools) along Section I and Section 2. Survey data included points measured at all breaks in slope including top of bank, bankfull, inner berm, edge of water, and thalweg. Dimensional characteristics were compared to baseline conditions. All monitored cross - sections should fall within the quantitative parameters defined for channels of the design stream type. Stream channel stability and geomorphic monitoring for Section 3 was documented visually. Natural variability is expected, however the system should not experience trends toward excessive increasing bank erosion, channel degradation, or channel aggradation. 2.1.2 Pattern and Profile The entire longitudinal profile of Section 1 and Section 2 was surveyed. Stationing from the as-built survey was used. The longitudinal profiles should show that the bedform features are remaining stable. The pools should remain deep with flat water surface slopes, and the riffles should remain steeper and shallower than the pools. 2.1.3 Sediment Transport As discussed in prior project documentation, additional sediment transport evaluations will not be undertaken during the five -year monitoring period. However, the dimension, pattern, and profile survey for MY4 conditions for Section 1 and Section 2 were analyzed to determine whether the current sediment competency and capacity is consistent with the design. 2.2 VEGETATION The Carolina Vegetation Survey (CVS) Level 2 methodology was utilized to sample vegetation on October 29, 2014. Nine 100 - square meter CVS plots have been established within the project area. In each plot, four plot corners have been permanently located with rebar. Volunteer plant species (Level 2) were recorded this year and will only be considered in vegetative success determinations for the stream portion of this project. As such, volunteer plant species will be recorded for subsequent monitoring years in vegetation plots located within the 50 foot buffer of the restored stream. Refer to Figure 2 in Appendix A. In all vegetation plots species composition, density, and survival of the planted vegetation was monitored. Oakley Crossroads (G) Stream and Buffer Restoration (Year 4 of 5) Page 3 Stantec - 2014 Monitoring Report (EEP# 273) December 2014 This project is generating both stream and riparian buffer mitigation assets. Vegetation success for these assets is measured in the following manners. Stream mitigation units (SMUs) require 260 planted and volunteer native hardwood stems (trees and shrubs) per acre for a minimum of 5 years. Buffer mitigation units (BMUs) require 260 stems per acre of planted native hardwood and volunteer stems (trees and shrubs) for a minimum of 5 years. In accordance with North Carolina Division of Water Quality Administrative Code 15A NCAC 0213.0295 (Mitigation Program for Requirements for Protection and Maintenance of Riparian Buffers) "[planted vegetation] shall include a minimum of at least four native hardwood tree species or four native hardwood tree and native shrub species, where no one species is greater than 50% of established stems at a density to provide 260 trees per acre at maturity. Native volunteer species may be included to meet performance standards." Also, for SMUs and BMUs, the buffer must be at least 30 -feet wide on both sides of the channel. The interim measure of vegetative success for SMUs for the site will be the survival of at least 320 3 -year old stems per acre at the end of year three of the monitoring period and 280 4 -year old stems per acre at the end of year four monitoring period. There are no interim measures of vegetative success for BMUs. 2.3 HYDROLOGY 2.3.1 Wetland Neither wetland restoration nor enhancement credit is being sought for this project. Existing jurisdictional wetlands as depicted in Figure 2 in Appendix A are being preserved. The wetland preservation areas are visually assessed during each monitoring year. 2.3.2 Stream One crest gauge has been installed onsite and is located near Cross - section 3. Each visit to the site included documentation of the highest stage for the monitoring interval and a reset of the device. Other . indications of bankfull flow including the presence of debris lines, sediment, or flooding were also monitored, and their presence was recorded and documented photographically. Refer to Figure 2 in Appendix A for the location of the crest gauge.
