The Project will provide streamand wetlandmitigation credits in the NeuseRiver Basin (Cataloging Unit 03020201). The project site is in Johnston County, North Carolina, between the Town of Wendell and the Community ofArcher Lodge. The Project isin the Lower Buffalo Creek Priority Sub-watershed 030202011504, study area for the Neuse 01 Regional Watershed Plan Phase II, Final Report (RWP), and in the Targeted Local Watershed 03020201180050, of the Neuse River Basin. The Projectinvolved the restoration, enhancement, and preservation of eightstream reaches (MS-R1, MS-R2, R3 (upper), R3 (lower), R4, R5 (upper), R5 (lower), and R6)with designedtotalsofapproximately 5,029linear feet of streams. The Project also includesriparian wetland restoration (re-establishment)and enhancementof approximately 3.495acres. The Project provides significant ecological improvements and functional uplift through stream and wetland restoration and will decrease nutrient,and sediment loads within the watershed. See Section 2for a detailed benefits summary and Table 1 for a summary of project assets. Figure 1aillustrates the project mitigation components. Prior to construction, many of the existing streamswereincised and degradeddue to excess bank erosion and increased stormwater flows. Wetland hydrology was drained acrossthe floodplain and areas mapped with hydric soils. The existing vegetation within the riparian corridorconsistsof mixed hardwood forest with some disturbed pine forest. Adjacent land use consists of agriculture, silviculture,and residential development. Monitoring Year 2(MY2) activities occurred during August and September 2022. This report presents the data for MY2. The Project meets the MY2success criteria for stream hydrology, stream horizontal and vertical stability,andstreambed condition and stability. Of the eight vegetation plots, one is not meeting interim success criteria.Fourof the sevenwetlands metsuccess criteria for hydrology.Based on these results, the Project is on trajectory to meet interim and final success criteria. For more information on the chronology of the project history and activity, refer to Appendix E. Relevant project contact information is presented in Appendix E and project background information is presented in Table 3. 1.2ProjectQuantitiesandCredits The Project mitigation components include a combination of Stream Restoration, Enhancement and Preservation activities, as well as Riparian Wetland Re-establishment and Enhancement, as summarized in the table below.

More specifically, three out of the four functional goals and objectives outlined inthe Wake-Johnston Collaborative Local Watershed Plan (LWP) as well as the Neuse 01 RWP will be met by: Reducing sediment and nutrient inputs to the Buffalo Creek Watershed. Restoring, preserving,and protecting wetlands, streams, riparian buffers and aquatic habitat. Implementing stream restoration in rural catchments together as “project clusters.” To accomplish these project-specific goals, the following objectives will be measured to document overall project success: Restore stream and floodplain interaction and geomorphically stable conditions by reconnecting historic flow paths and promoting more natural flood processes; Improve and protect water quality by reducing streambank erosion, nutrient and sediment inputs; Restore and protect riparian buffer functions and habitat connectivity in perpetuity by recording a permanent conservation easement; and Incorporate water quality improvement features to reduce nonpoint source inputs to receiving waters.

Cross-section and vegetation plot data will be collected in Years 0, 1, 2, 3, 5, and 7. Stream hydrology data and visual monitoring will be reported annually. Specific success criteria components and evaluation methods are described below. 2.2.1Streams Stream Hydrology:Four separate bankfull or over bank events must be documented within the seven-year monitoring period and the stream hydrology monitoring will continue until four bankfull events have been documented in separate years. Stream hydrology monitoring will be accomplished with pressure transducers installed in pools and correlating sensor depth to top of bank elevation(see appendix D for installation diagrams). Recorded water depth above the top of bank elevation will document a bankfull event. The devices will record water depth hourly and will be inspected quarterly. The stage recorders include an automatic pressure transducer (HOBO Water Level (13 ft) Logger) set in PVC piping in the channel. The elevation of the bed and top of bank at each stage recorder location will MY2 FINALBuffalo CreekTributaries DMS Project #100042 5 berecorded to be able to document presence of water in thechannel and out of bank events. Visual observations (i.e. wrack or debris lines) and traditional cork crest gauges will also be used to document out of bank events. Stream Profiles, Vertical Stability, and Floodplain Access: Stream profiles, as a measureof vertical stability and floodplain access will be evaluated by looking at Bank Height Ratios (BHR). In addition, observed bedforms should be consistent with those observed for channels of the design stream type(s). The BHR shall not exceed 1.2 along riffles within the restored Project stream reaches. This standard only applies to restored reaches of the channel where BHRs were corrected through design and construction. Vertical stability will be evaluated with visual assessment, cross-sections and, if directed by the IRT, longitudinal profile. Stream Horizontal Stability:Cross-sections will be used to evaluate horizontal stream stabilityon restored streams.There should be little change expected in as-built restoration cross-sections. If measurable changes do occur, they should be evaluated to determine if the changes represent a movement toward a more unstable condition (e.g., downcutting, erosion) or a movement towards increased stability (e.g., settling, vegetation establishment, deposition along the streambanks, decrease in width/depth ratio). Cross-sections shall be classified using the Rosgen Stream Classification method and all monitored cross- sections should fall within the quantitative parameters defined for channels of the design stream type. Stream cross-section monitoring will beconducted using a TopconTotal Station. Three-dimensional coordinates associated with cross-section data will becollected in the field (NAD83 State Plane feet FIPS 3200). Morphological data will becollected at 13cross-sections. Surveydata will beimported into Microsoft Excel® and the DMS Shiny App for data processing and analysis. Reference photo transects will be taken at each permanent cross-section. Lateral photos should not indicate excessive erosion or continuing degradation of the streambanks. Photographs will be taken of both streambanks at each cross-section. A survey tape stretched between the permanent cross-section monuments/pins will be centered in each of the streambank photographs. The water elevation will be shown in the lower edge of the frame, and as much of the streambank as possible will be included in each photo. Photographers willattempt to consistently maintain the same area in each photo over time. Streambed Material Condition and Stability:Streambed material should not significantly change over time and any significant changes (e.g., aggradation, degradation, embeddedness) will be noted after streambank vegetation becomes established and a minimum of two bankfull flows or greater have been documented. If significant changes are observed within stable riffles and pools, additional sediment transport analyses may be required. Jurisdictional Stream Flow:Monitoring of stream flow will be conducted to demonstrate that the restored stream systems classified as intermittent exhibit surface flow for a minimum of 30 consecutive days throughout some portion of the year during a year with normalrainfall conditions. Stream flowmonitoring will be accomplished with pressure transducers installed in pools and correlating sensor depth to the downstream top of riffle elevation(see appendix D for installation diagrams). If the pool water depth is at or above the top of riffle elevation,then the channel will be assumed to have surface flow. The devices will record water elevation twice per day and will be inspected quarterly to document surface hydrology and provide a basis for evaluating flow response to rainfall events. MY2 FINALBuffalo CreekTributaries DMS Project #100042 6 2.2.2Wetlands Wetland Hydrology:The performance standard for wetland hydrology will be 12percent based on the suggested wetland saturation thresholds for soils taxonomic subgroups. The proposed success criteria for wetland hydrology will be when the soils are saturated within 12 inches of the soil surface for 12percent (27days) of the 227-day growing season (March21stthrough November3rd) based on WETS data table for JohnstonCounty, NC. The saturated conditions should occur during a period when antecedent precipitation has been normal or drier than normal for a minimum frequency of 5 years in 10 (USACE, 2005 and 2010b). Precipitation data will be obtained from an on-site rain gauge,installed at the Odell’s House Mitigation Project,and the Clayton (CLAY) Research Weather Station, approximatelyninemiles southeastof the Project site. If a normal year of precipitation does not occur during the first seven years of monitoring, WLS will continue to monitor the Project hydrology until the Project site has been saturated for the appropriate hydroperiod. If rainfall amounts for any given year during the monitoring period are abnormally low, reference wetland hydrology data will be compared to determine if there is a correlation with the weather conditions and site variability. Wetland hydrology will be monitored to document success in wetland restoration and enhancement areas where hydrology was affected. This will be accomplished with automatic pressure transducer gauges (located in groundwater wells) that record daily (twice per day) groundwater levels. The pressure transducer gauges are HOBO Water Level (13ft) Loggers made by Onset. Seven gaugeswill beinstalled within the wetland crediting areas. One automatic pressure transducer will beinstalled above ground for use as a barometric reference. One rain gauge will be installedat the adjacent Odell’s House Mitigation Project site (0.3 miles southeast of the project) to document rainfall at the project. Gauges are downloaded quarterly and wetland hydroperiods are calculated during the growing season. Gauge installationwillfollowcurrent regulatory guidance.Gauge data is downloaded using a HOBO Onset Waterproof Shuttle Data Transporter.Visual observations of primary and secondary wetland hydrology indicators willalso be recorded during quarterly site visits. 2.2.3Vegetation Vegetation monitoring will occur in the fall each required monitoring year, prior to leaf drop. Plots will be monitored in years 1, 2, 3, 5, and 7. Vegetative success for the Project during the intermediate monitoring years will be basedonthe survival of at least 320, three-year-old trees per acre at the end of Year 3 of the monitoring period; and at least 260, five-year-old, trees per acre that must average sevenfeet in height at the end of Year 5 of themonitoring period. The final vegetative restoration success criteria will be achieving a density of no less than 210, seven-year-old stems per acre that must average tenfeet in height in Year 7 of monitoring.Volunteer species on the approved planting list that meet success criteria standards will be counted towards success criteria. Vegetation success is being monitored at a total of sixpermanent vegetation plots(10m x 10mor 20m x 5m) and two random vegetation transects(50m x 2m).Vegetation plot monitoring follows the CVS-EEP Level 2 Protocol for Recording Vegetation, version 4.2 (Lee et al. 2008) and includes analysis of species composition and density of planted species. Data will beprocessed using theDMS ShinyApp. For each plot,the origin will bemarked with a PVC pole and the other three corners marked with rebar. Tree species and height will be recorded for each planted stem and photos of each plot are to be taken from the origin each monitoring year. MY2 FINALBuffalo CreekTributaries DMS Project #100042 7 2.2.4Visual Assessment WLS will conduct visual assessments in support of mitigation performance monitoring. Visual assessments of all stream reaches will be conducted twice per monitoring year with at least five months in between each site visit for each of the seven years of monitoring. Photographs will be used to visually document system performance and any areas of concern related to streambank and bed stability, condition of in- stream structures, channel migration, active headcuts, live stake mortality, invasive plant species or animal browsing, easement boundary encroachments, and general streambed conditions.Permanent photo points will be at the cross-sectionsandculvert crossings. 3ProjectAttributes 3.1DesignApproach The Project stream design approach included a combination of Stream Restoration, EnhancementLevelI, and Preservationactivities(Table 1). A Priority Level I restoration approach was incorporated with the design of both a single-thread meandering channelalong the main stem (MS-R1 and MS-R2) and step- pool channels (R3, R4, R5 and R6). All non-vegetated or disturbed areas within the conservation easement were planted with native species vegetation and any areas of invasive species were removed and/or treated. 3.2ProjectAttributes See Table 3 below for Project attributes MY2 FINALBuffalo CreekTributaries DMS Project #100042 8 Table 3.

Refer toAppendices A and C for summary data tables, morphological plots, and stream photographs. 4.1.1 Stream Horizontal Pattern & Longitudinal Profile The MY2 visual observations of stream horizontal pattern and longitudinal profiles closely match the design parametersand did not show any significant deviation from as-built conditions. Theminor channel adjustments in riffle slopes, pool depthsand patterndo notpresent a stability concernor indicate a need for remedial action and will be assessed visually during theannual assessments. 4.1.2 Stream Horizontal Dimension The MY2 channel dimensions generally match thedesign parametersand are within acceptable andstable ranges of tolerance. Thirteencross-sections are located in restorationand enhancementreaches across the project. Of the thirteen cross-sections, nine are located in rifflesand four are located in pools. All thirteen cross-sections show little change in bankfull area, and all bank height ratios are less than 1.2. It is expected over timethat some pools may accumulate finesediment and organic matter, however,this is notan indicator ofchannel instability. Maximum riffle depths are also expected tofluctuate slightly throughout the monitoring period as the channels adjust to newflow regime. 4.2StreamHydrology 4.2.1Stream Flow Twopressure transducers (flow gauges) were installed in March and April2021 onreaches R4 and R6 to document baseflow conditions. The flow gauge locations are within the upper one-third of the project reaches as shown on the CCPV. Both flow gauges exhibitedflow for a minimum of 30 days in MY2. Additionally, to determine if rainfall amounts are normal for the given year, precipitation data was obtained from a rain gauge installed at Odell’s HouseMitigation Project (DMS #100041)less than a mile south ofthe Project site.

WLS installed a conventional cork crest gauge, along with a pressure transducer to documentflood statuson MS-R2. During MY2, bankfull events were recorded on the pressure transducer crest gauge. CG-1 recorded fiveevents with a th maximum event of 0.945 feet above bankfullon August12, 2022. 4.3Wetlands Sevenwetland groundwater wells were installed in March and April2021to monitor wetland hydrology. Wetland groundwater well locations are shown on the CCPV.During MY2, fourof theseven wetland groundwater wells met the twelve percent wetland hydrology criteria.GW-1, GW-2, and GW-7did not meet hydrology criteria andhad hydroperiodsof 10.13percent, 10.57 percent, and4.85 percent, respectively. GW-1 and GW-2 are close to meeting success criteria and no additional gauges are proposed at this time. An additional gauge will be installed in W3to better capture hydrology during the winter of 2022. These areasareexpected to continue to increase hydroperiod length in 2023as groundwater continues to recharge. 4.4 Vegetation Monitoring of thesixpermanent vegetation plotsand two random transectswas completed during September2022. Vegetationdata and photos can be found in Appendix B. The MY2average planted density is 526stems per acre, which exceeds the interim measure ofvegetativesuccess of at least 320 planted stems per acre at the end of the third monitoring year.Seven of the eight vegetationplotsmeet the interim successrequirements,and the eight plots have a range of 283-810stems per acre.Vegetation plot 1 is below success criteria by 1 stem, the low stem count is likely due to wetness and thick herbaceous cover.No remedial action is proposed at this time.Volunteer ironwood(Carpinus caroliniana), tulip poplar (Liriodendron tulipifera), and hazel alder (Alnus serrulata) were noted during monitoring year 2. Visual assessment of vegetation outside of the monitoring plots indicates that the herbaceous vegetation is becoming well established throughout the project. nd An area of concernwasnoted during a DMS site visit on July 2, 2021,ofoverland flow occurring along MS-R1 from an offsite BMP. This area is stablewith dense herbaceousvegetation preventing soil erosion and there are no significant impacts to the floodplain or the stream(see photos in Appendix A). This area will continue to be monitored and any remedial actions will be documented in future reports. During MY1 there were two encroachments (~0.014 acres)observednear the southernmost culvert crossing on MS-R2.Both wererecently sodded/planted grassy areasadjacenttonewhome construction. Toprevent further encroachment,the homeowners werecontacted,and the easement line wasmore th clearly marked. Encroachment planting occurred on January 6, 2022,using one-gallon trees (seeplanting list below). During MY2,no further encroachments have occurred in these areas. A new encroachment th (~0.0005acres)was noted onAugust 18, 2022. The landowner was contacted,and the easement was more clearly marked to prevent future mowing (see photos in Appendix A).
