( Wildlands) completed a full delivery project at the Agony Acres Mitigation Site (Site) for the North Carolina Ecosystem Enhancement Program (NCEEP) to restore, enhance, and preserve a total of 9,195 linear feet (LF) of perennial and intermittent stream in Guilford County, NC. The Site generated 6,596 Stream Mitigation Units (SMUs) and 3.0 Buffer Mitigation Units (BMUs). This site is located in the Reedy Fork Watershed within Cape Fear River Basin Hydrologic Unit Code (HUC) 03030002 (Cape Fear 02) near Ossipee, NC (Figure 1). The streams are all tributaries to Reedy Fork and are referred to herein as UT1, UT1A, UT113, and UT2. The Site also includes 3.0 acres of riparian buffer restoration along Reedy Fork and UT1. The Site is located within the Jordan Lake Water Supply Watershed which has been designated as a Nutrient Sensitive Water. The Site's watershed is within Cape Fear local watershed HUC 03030002020070, which was not identified as a Cape Fear 02 Targeted Local Watershed (TLW) in NCEEP's 2009 Cape Fear River Basin Restoration Priority (RBRP) plan; however, this local watershed was later designated as a Targeted Resource Area (TRA) in the 2011 Request for Proposals (RFP) in the Cape Fear 02. The Agony Acres Mitigation Site fully supports the Cataloging Unit (CU) -wide functional objectives stated in the 2011 RFP to reduce and control nutrient inputs, reduce and control sediment inputs, and protect and augment Significant Natural Heritage Areas in the Cape Fear 02 River Basin. The Project will contribute to meeting the CU -wide Functional Improvement Objectives by establishing the following project goals: • Reduce sediment inputs by removing cattle from streams and restoring degraded and eroding stream channels; • Return a network of streams to a stable form that is capable of supporting biological functions; • Reduce fecal coliform, nitrogen, and phosphorous inputs through removing cattle from streams and establishing and augmenting a forested riparian corridor; • Protect existing high quality streams and forested buffers; and • Improve and protect hydrologic inputs to the adjacent Reedy Fork Aquatic Habitat Significant Natural Heritage Area. The project is helping meet the goals for the watershed outlined in the RBRP and provide numerous ecological benefits within the Cape Fear River Basin. While many of these benefits are limited to the Agony Acres project area, others, such as pollutant removal, reduced sediment loading, and improved aquatic and terrestrial habitat, have farther - reaching effects. The Site construction and as -built surveys were completed between August and December 2014. Minimal adjustments were made during construction, as needed, based on site conditions and availability of materials. Specific changes are detailed in Section 5.1. Baseline (MYO) profiles and cross section dimensions closely match the design parameters. The Site was built as designed and is on track to meeting the upcoming monitoring year's success criteria.

Report -FINAL Section 1: PROJECT GOALS, BACKGROUND AND ATTRIBUTES 1.1 Project Location and Setting The Agony Acres Mitigation Site (Site) is located in northeastern Guilford County, north of Gibsonville (Figure 1). From Gibsonville take NC 61 north 5.5 miles. Turn right on Sockwell Road. Travel 1.4 miles. The project site is located north of Sockwell Road and is bound on the north by Reedy Fork. The Site is located on six tracts owned by four different property owners. See Agony Acres Mitigation Plan Table 1 (2014) for property owners, and Parcel Identification Numbers (PIN). A conservation easement was recorded on 30.78 acres within six parcels (Deed Book 7558, Pages 828, 853, 904, and 927). The Site is located in the Reedy Fork Watershed within the Jordan Lake Water Supply Watershed which has been designated a Nutrient Sensitive Water. The project streams flow directly into Reedy Fork which flows into the Haw River and eventually into the Jordan Lake Reservoir. The Site's watershed is within Hydrologic Unit Code (HUC) 03030002020070 which was not identified as a Cape Fear 02 Targeted Local Watershed (TLW) in NCEEP's 2009 Cape Fear River Basin Restoration Priority (RBRP) plan; however, this HUC was later designated as a Targeted Resource Area (TRA) in the 2011 Request for Proposals (RFP) in the Cape Fear 02. The Site connects to Reedy Fork and three separate but connected Significant Natural Heritage areas. Reedy Fork Aquatic Habitat, Reedy Fork Slopes at NC 61, and Altamahaw Alluvial Forest are all listed on the NC Natural Heritage GIS database immediately adjacent to the project. There are also records for several state threatened, special concern, and significantly rare mussel species in Reedy Fork. The Site is located in the Carolina Slate Belt of the Piedmont Physiographic Province. The Piedmont Province is characterized by gently rolling, well- rounded hills with long low ridges, with elevations ranging anywhere from 300 to 1500 feet above sea level. The Carolina Slate Belt consists of heated and deformed volcanic and sedimentary rocks. Approximately 550 to 650 million years ago, this region was the site of a series of oceanic volcanic islands. The belt is known for its numerous abandoned gold mines and prospects. Specifically, the Site is located in the CZfv subregion within the Carolina Slate Belt. The CZfv sub region is classified as felsic metavolcanic rock. These rock types are described as metamorphosed dacitic to rhyolitic flows and tuffs interbedded with mafic and intermediate metavolcanic rock, meta - argillite and metamudstone. NCEEP completed a Local Watershed Plan (LWP) in 2008 on the HUC immediately downstream which begins at the confluence of Reedy Fork and the Haw River and includes Travis and Tickle Creeks. The Site is located less than one mile outside of the LWP area and has a very similar land use pattern. The 2008 Little Alamance, Travis, and Tickle Creeks LWP identified nutrient inputs from agriculture and stream bank erosion in altered reaches as major stressors within this TLW. The Site was identified as a stream and buffer restoration and cattle exclusion opportunity to improve water quality and buffers within the TRA. Restoration goals for the downstream LWP area are defined in the 2008 Little Alamance, Travis, and Tickle Creeks LWP. The primary goals for the agricultural regions of the LWP area are to promote nutrient and sediment reduction by restoring streams and riparian buffers and excluding livestock. The Cape Fear 02 2011 RFP established three CU -wide Functional Improvement Objectives as listed below: • To reduce and control sediment inputs; • To reduce and control nutrient inputs; and • To protect and augment Significant Natural Heritage Areas. The four tributaries to Reedy Fork on the Site are located within the North Carolina Division of Water Resources ( NCDWR) subbasin 03 -06 -02 of the Cape Fear River Basin. The NCDWR assigns best usage Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 1 -1 classifications to State Waters that reflect water quality conditions and potential resource usage. None of the four tributaries are classified by NCDWR and therefore are required to meet standards for Class C waters. Class C waters are protected for secondary recreation, fishing, and aquatic life. Reedy Fork (NCDWR Index No. 16- 11 -(9)) is classified as Water Supply V — Upstream (WS -V) and Nutrient Sensitive Waters (NSW) by NCDWR. Class WS -V waters are protected as water supplies and typically flow into other water bodies that are directly used as sources for drinking, culinary or food processing purposes. NSW classification represents water bodies that require nutrient management plans to reduce water quality impacts due to excessive nitrogen and phosphorus levels and algal populations. Prior to construction activities, the stream channels exhibited varying degrees of degradation across the site. The site was used as agricultural and pasture land and most of the buffers had been maintained to narrow corridors to maximize agricultural and pasture land. Cattle also had free access to the streams, which resulted in sporadic degraded stream banks and poor bed forms. The streams on the Site that were restored were previously severely over - enlarged channels that were extremely deep in many locations. The alterations of the Site to promote cattle grazing and farming resulted in elimination of many of the ecological functions of this small stream /wetland complex. Specifically, functional losses at the Site included degraded aquatic habitat, altered hydrology (related to loss of floodplain connection and lowered water table), and reduction of quality and amount of riparian wetland habitats and related water quality benefits. Ongoing bank erosion was also occurring at some locations due to high, overly steep banks and lack of bank vegetation. Table 4 in Appendix 1 and Tables 5a -d in Appendix 2 present the pre- restoration conditions in detail. 1.2 Project Goals and Objectives The mitigation project is intended to provide numerous ecological benefits within the Cape Fear River Basin. While many of these benefits are limited to the Agony Acres Mitigation Site project area, others, such as pollutant removal and improved aquatic and terrestrial habitat, have more far - reaching effects. Expected improvements to water quality and ecological processes are outlined below as project goals and objectives. These project goals were established and completed with careful consideration of goals and objectives that were described in the RBRP and to meet the North Carolina Ecosystem Enhancement Program's (NCEEP) mitigation needs while maximizing the ecological and water quality uplift within the watershed. The following project specific goals established in the mitigation plan (Wildlands, 2014) include: • Reduce sediment inputs by removing cattle from streams and restoring degraded and eroding stream channels; • Return a network of streams to a stable form that is capable of supporting biological functions important to sensitive species within and adjacent to the project site; • Reduce fecal coliform, nitrogen, and phosphorous inputs through removing cattle from streams and establishing and augmenting a forested riparian corridor; • Protect existing high quality streams and forested buffers that provide habitat important to sensitive species within and adjacent to the project site; • Improve and protect hydrologic inputs to the adjacent Reedy Fork Aquatic Habitat Significant Natural Heritage Area; and • Improve and protect hydrologic inputs to Reedy Fork, which is listed as impaired on the 2012 NC 303(d) list for impaired aquatic life and for elevated fecal coliform levels. The project goals will be addressed through the following project objectives: Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 1 -2 • On -site nutrient inputs were decreased by removing cattle from streams, re- establishing floodplain connectivity, 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 creeks was greatly reduced, if not eliminated, in the project area. Eroding stream banks were stabilized using bioengineering, natural channel design techniques, and grading to reduce bank angles and bank height. Storm flow containing grit and fine sediment is filtered through restored floodplain areas, where flow will spread through native vegetation. Spreading flood flows also reduces velocity and allows sediment to settle out. Sediment transport capacity of restored reaches was improved so that capacity balances more closely to load. Sediment load reduction will be monitored through assessing bank stability with cross section surveys and visual assessment through photo documentation which serves as an accepted surrogate for direct turbidity measurements. • Restored riffle /pool sequences promote aeration of water and create deep water zones, helping to lower water temperature. Establishment and maintenance of riparian buffers creates long- term shading of the channel flow to minimize thermal heating. Lower water temperatures will help maintain dissolved oxygen concentrations. • In- stream structures were constructed to improve habitat diversity and trap detritus. Wood habitat structures were included in the stream as part of the restoration design. Such structures include log drops and rock structures that incorporate woody debris and native onsite rock. • Adjacent buffer and riparian habitats were restored with native vegetation as part of the project. Native vegetation provides cover and food for terrestrial creatures. Native plant species were planted and invasive species treated. Eroding and unstable areas were stabilized with vegetation as part of this project. • The restored land is protected in perpetuity through a conservation easement. 1.3 Project Structure, Restoration Type and Approach 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. Specifically, the site design was developed to restore a small stream complex directly adjacent to the Reedy Fork to a naturally occurring community to create riparian habitat and improve water quality. Other key factors addressed in the design were to create stable habitats, improve riparian buffers, and restore the natural migration patterns for fish spawning. Figure 2 and Table 1 in Appendix 1 present the stream mitigation components for the Agony Acres Mitigation Site. The final mitigation plan was submitted and accepted by the NCEEP in March 2014. Construction activities were completed by Land Mechanic Designs, Inc in September 2014. The planting was completed by Bruton Natural Systems, Inc. in December 2014. The baseline as -built survey was completed by Kee Mapping and Surveying, in October 2014. There were no significant deviations reported in the as -built project elements compared to the design plans. A few structures were either added, eliminated, or adjusted slightly based on field conditions. Field adjustments made during construction are described in detail in section 5.1. Appendix 1 provides more detailed project activity, history, contact information, and watershed /site background information for this project. 1.3.1 Project Structure The project will provide 6,596 stream mitigation units (SMUs) and 3.0 buffer mitigation units (BMUs). Please refer to Figure 2 for the project component /asset map for the stream restoration feature exhibits Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 1 -3 and Table 1 for the project component and mitigation credit information for the Agony Acres Mitigation Site. 1.3.2 Restoration Type and Approach 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 Site consists of stream restoration, enhancement, and preservation (Figure 2). The specific proposed stream types are described below. The stream restoration portion of this project includes six reaches: • UT1 -Reach 2: UT1 from approximately 1100 feet downstream of Sockwell Road to a sharp bend due east, approximately 1200 feet in length; • UT1 -Reach 5: UT1 beginning at the confluence with UT1A to its terminus with Reedy Fork, approximately 1500 feet in length; • UT1A -Reach 1: UT1A beginning at Sockwell Road for a length of approximately 850 feet; • UT1A -Reach 4: UT1A beginning approximately 700 feet upstream of the confluence with UT1 to its terminus with UT1; • UT113: UT113 beginning at the conservation easement to its terminus with UT1, approximately 200 feet; and • UT2: UT2 beginning at an existing fence line to its terminus with Reedy Fork, approximately 1000 feet. The project also includes stream enhancement on four reaches classified as either enhancement I (El) or enhancement II (Ell): • UT1 -Reach 1, Ell: UT1 beginning at Sockwell Road for a length of approximately 1100 feet; • UT1 -Reach 2, El: UT1 beginning near a sharp bend due east for a length of approximately 100 feet; • UT1 -Reach 4, El/Ell: UT1 beginning at an existing ford crossing to the confluence with UT1A, approximately 700 feet in length; and UT1A -Reach 2, Ell: UT1A beginning approximately 800 feet downstream of Sockwell Road to a sharp change in channel slope and bedrock material, approximately 300 feet in length. Additionally, there are two preservation reaches: • UT1 -Reach 3: UT1 beginning approximately 100 feet after a sharp bend due east to an existing ford crossing, approximately 1400 feet in length; • UT1A -Reach 3: UT1A beginning at a sharp change in channel slope and bedrock material for a length of approximately 500 feet. For UT1 -Reach 3 and UT1A -Reach 3, the streams have not been heavily impacted by cattle and overall stream health is relatively good. For these reaches, preservation was proposed; mainly consisting of fencing out cattle. The restoration reaches were designed to be similar to C -type streams according to the Rosgen classification system (Rosgen, 1996). Type C streams are slightly entrenched, meandering streams with access to the floodplain (entrenchment ratios >2.2) and channel slopes of 2% or less. They occur within a wide range of valley types and are appropriate for the project landscape. The morphologic design parameters are shown in Appendix 2, Tables 5a through 5d for the restoration reaches, and fall within the ranges specified for C streams (Rosgen, 1996). The specific values for the Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 1 -4 design parameters were selected based on designer experience and judgment and were verified with morphologic data form reference reach data sets. 1.4 Project History, Contacts and Attribute Data The Site was restored by Wildlands Engineering, Inc. ( Wildlands) through a full delivery contract with NCEEP. Tables 2, 3, and 4 in Appendix 1 provide detailed information regarding the Project Activity and Reporting History, Project Contacts, and Project Baseline Information and Attributes. Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 1 -5 Section 2: SUCCESS CRITERIA The stream and buffer performance criteria for the project site will follow approved performance criteria presented in the NCEEP Mitigation Plan Template (version 2.1, 09/01/2011), the NCEEP Monitoring Requirements and Performance Standards for Stream and /or Wetland Mitigation (11/7/2011), and the Stream Mitigation Guidelines issued in April 2003 by the United States Army Corps of Engineers ( USACE) and NCDWR. Annual monitoring and semi - annual site visits will be conducted to assess the condition of the finished project. The stream restoration and enhancement sections and the buffer restoration sections of the project will be assigned specific performance criteria components for stream morphology (stream only), hydrology (stream only), and vegetation (stream and buffer). Performance criteria will be evaluated throughout the seven year post- construction monitoring period. If all performance criteria have been successfully met and two bankfull events have occurred during separate years, Wildlands may propose to terminate stream and /or vegetation monitoring. An outline of the performance criteria components follows. 2.1 Streams 2.1.1 Dimension Riffle cross sections on the restoration and El reaches should be stable and should show little change in bankfull area, maximum depth ratio, and width -to -depth ratio. Per NCEEP guidance, bank height ratios shall not exceed 1.2 and entrenchment ratios shall be at least 2.2 for restored channels to be considered stable. Reach riffle means should fall within the parameters defined for channels of the appropriate Rosgen stream type. If any changes do occur, these changes will be evaluated to assess whether the stream channel is showing signs of instability. Indicators of instability include a trend in vertical incision or eroding channel banks over the monitoring period. Changes in the channel that indicate a movement toward stability or enhanced habitat include a decrease in the width -to -depth ratio in meandering channels or an increase in pool depth. Remedial action would not be taken if channel changes indicate a movement toward stability. 2.1.2 Pattern and Profile Longitudinal profile surveys will not be conducted during the seven year monitoring period unless other indicators during the annual monitoring indicate a trend toward vertical and lateral instability. If a longitudinal profile is deemed necessary, monitoring will follow standards as described in the NCEEP Monitoring Requirements and Performance Standards for Stream and /or Wetland Mitigation (11/7/2011) and the 2003 USACE and NCDWR Stream Mitigation Guidance for the necessary reaches. Visual assessments and photo documentation should indicate that streams are remaining stable and do not indicate a trend toward vertical or lateral instability. 2.1.3 Substrate A reach -wide pebble count will be performed in each restoration and El reach each year for classification purposes. A pebble count will be performed at each surveyed riffle to characterize the pavement. Substrate materials in the restoration and El reaches should indicate a progression towards or the maintenance of coarser materials in the riffle features and smaller particles in the pool features. kAgony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 2 -1 2.1.4 Photo Documentation Photographs should illustrate the site's vegetation and morphological stability on an annual basis. Cross section photos should demonstrate no excessive erosion or degradation of the banks. Longitudinal photos should indicate the absence of persistent bars within the channel or vertical incision. Grade control structures should remain stable. Deposition of sediment on the bank side of vane arms is preferable. Maintenance of scour pools on the channel side of vane arms is expected. 2.1.5 Hydrology Documentation Two bankfull flow events must be documented on the restoration and enhancement reaches within the seven -year monitoring period. The two bankfull events must occur in separate years. Stream monitoring will continue until success criteria in the form of two bankfull events in separate years have been documented. In addition, the presence of baseflow must be documented along portions of UT1B constructed with a Priority I restoration approach. Baseflow must be present for at least some portion of the year (most likely in the winter /early spring) during years with normal rainfall conditions. 2.2 Vegetation The final vegetative success criteria for the stream restoration and enhancement areas will be the survival of 210 planted stems per acre in the riparian corridor at the end of the required monitoring period (year seven). The interim measure of vegetative success will be the survival of at least 320 planted stems per acre at the end of the third monitoring year and at least 260 stems per acre at the end of the fifth year of monitoring. Planted vegetation must average 10 feet in height in each plot at the end of the seventh year of monitoring. If this performance standard is met by year five and stem density is trending towards success (i.e., no less than 260 five year old stems /acre), monitoring of vegetation on the site may be terminated with written approval by the USACE in consultation with the NC Interagency Review Team. The extent of invasive species coverage will also be monitored and controlled as necessary throughout the required monitoring period. The final vegetative success criteria for the buffer restoration areas will be the survival of 320 planted stems per acre in the riparian corridor at the end of the required monitoring period (year five). 2.3 Schedule and Reporting Monitoring reports will be prepared in the fall of each year of monitoring and submitted to NCEEP. Based on the NCEEP Monitoring Report Template (version 1.4, 11/7/2011), the monitoring reports will include the following: • Project background which includes project objectives, project structure, restoration type and approach, location and setting, history and background; • As -built topographic plans of major project elements including such items as grade control structures, vegetation plots, permanent cross sections, crest gages, and pressure transducers; • Photographs showing views of the restored Site taken from fixed point stations; • Assessment of the stability of the Site based on the cross sections and longitudinal profile, where applicable; • Vegetative data as described above including the identification of any invasion by undesirable plant species; • Stream flow gage attainment; Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 2 -2 • A description of damage by animals or vandalism; • Maintenance issues and recommended remediation measures will be detailed and documented; and • Wildlife observations. Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 2 -3 Section 3: MONITORING PLAN Monitoring will consist of collecting morphological, vegetative, and hydrological data to assess the project success based on the restoration goals and objectives on an annual basis or until success criteria is met. The success of the project will be assessed using measurements of the stream channel's dimension, pattern, substrate composition, permanent photographs, vegetation, and surface water hydrology. Any areas with identified high priority problems, such as streambank instability, aggradation /degradation, or lack of vegetation establishment will be evaluated on a case -by -case basis. The problem areas will be visually noted and remedial actions will be discussed with NCEEP staff to determine a plan of action. A remedial action plan will be submitted if maintenance is required. The monitoring period will extend seven years beyond completion of construction or until performance criteria have been met. 3.1 Stream Geomorphic assessments will follow guidelines outlined in the Stream Channel Reference Sites: An Illustrated Guide to Field Techniques (Harrelson et al., 1994), methodologies utilized in the Rosgen stream assessment and classification document ( Rosgen, 1994 and 1996), and in the Stream Restoration: A Natural Channel Design Handbook (Doll et al, 2003). Please refer to Appendix 4 for monitoring locations discussed below. 3.1.1 Dimension A total of 16 cross sections were installed along the stream restoration and El reaches. Two cross sections were installed per 1,000 linear feet of stream restoration work, with riffle and pool sections in proportion to NCEEP guidance. The mitigation plan (Wildlands, 2014) called for thirty two cross sections, but after discussions with NCEEP, it was determined that the wrong formula was used to calculate the number of cross sections needed on the Site. Therefore, with verbal approval from NCEEP, the correct number of cross sections were calculated and installed on the Site. Each cross section was permanently marked with pins to establish its location. Cross section surveys include points measured at all breaks in slope, including top of bank, bankfull, edge of water, and thalweg to monitor any trends in bank erosion. If moderate bank erosion is observed at a stream reach during the monitoring period, a series of bank pins will be installed in representative areas where erosion is occurring for reaches with a bankfull width of greater than three feet. Bank pins will be installed in at least three locations (one in upper third of the pool, one at the mid- point of the pool, and one in the lower third of the pool). Bank pins will be monitored by measuring exposed rebar and maintaining pins flush to bank to capture bank erosion progression. Annual cross section and bank pin surveys (if applicable) will be conducted in monitoring years one (MY1), two (MY2), three (MY3), five (MY5), and seven (MY7). Photographs will be taken annually of the cross sections looking upstream and downstream. 3.1.2 Pattern and Profile Longitudinal profile surveys will not be conducted during the seven year monitoring period unless other indicators during the annual monitoring show a trend toward vertical and lateral instability. If a longitudinal profile is deemed necessary, monitoring will follow standards as described in the NCEEP Monitoring Requirements and Performance Standards for Stream and /or Wetland Mitigation (11/7/2011) and the 2003 USACE and NCDWR Stream Mitigation Guidance for the necessary reaches. Stream pattern and profile will be assessed visually as described below in section 3.1.6. Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 3 -1 3.1.3 Substrate A reach -wide pebble count will be performed in each restoration reach each year for classification purposes. A pebble count will be performed at each surveyed riffle to characterize the pavement. 3.1.4 Photo Reference Points A total of 42 permanent photograph reference points were established within the project area after construction. Photographs will be taken once a year to visually document stability for seven years following construction. Permanent markers were established so that the same locations and view directions on the site are monitored each year. Photographs will be used to monitor stream restoration and enhancement reaches. The photographer will make every effort to maintain the same view in each photo over time. The representative digital photo(s) will be taken on the same day(s) the surveys are conducted. 3.1.5 Hydrology Documentation Four manual crest gages and four pressure transducer automated gages were installed on the Site (Appendix 4). The crest gages and transducers were installed at four surveyed riffle cross sections along UT1 reach 2, UT1A Reach 4, UT1B, and UT2 and will be checked during each site visit to determine if a bankfull event has occurred since the last visit. Photographs will be used to document the occurrence of debris lines and sediment deposition as evidence of bankfull events. Additionally, the pressure transducer data will be plotted and included in the annual monitoring reports. Baseflow in UT113 will be confirmed by two pressure transducer automated gages installed at the thalweg elevation of the channel. One transducer is located at the upper end of the reach, and one at the downstream end. The transducers are equipped with auto logging gages that are capable of monitoring stream stage. A rating curve has been developed for each of the transducer locations to correlate stage to discharge. Discharge data will be provided annually in the monitoring reports to demonstrate intermittent aquatic function has been maintained in the restored channel. 3.1.6 Visual Assessment Visual assessments will be performed along all stream and buffer restoration areas on a semi - annual basis during the seven year monitoring period. Problem areas will be noted such as channel instability (i.e. lateral and /or vertical instability, in- stream structure failure /instability and /or piping, headcuts), vegetated health (i.e. low stem density, vegetation mortality, invasive species or encroachment), beaver activity, or livestock access. Areas of concern will be mapped and photographed accompanied by a written description in the annual report. Problem areas will be re- evaluated during each subsequent visual assessment. Should remedial actions be required, recommendations will be provided in the annual monitoring report. 3.2 Vegetation Planted woody vegetation will be monitored in accordance with the guidelines and procedures developed by the Carolina Vegetation Survey -NCEEP Level 2 Protocol (Lee et al., 2006) to monitor and assess the planted woody vegetation. A total of 16 standard 10 meter by 10 meter vegetation plots were established within the project easement area. Vegetation plots were randomly established within the planted corridor of the restoration areas to capture the heterogeneity of the designed vegetative communities. The vegetation plot corners have been marked and are recoverable either through field identification or with the use of a GPS unit. Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 3 -2 Reference photographs were taken at the origin looking diagonally across the plot to the opposite corner during the baseline monitoring in January 2015. Subsequent annual assessments following baseline survey will capture the same reference photograph locations. Species composition, density and survival rates will be evaluated on an annual basis by plot and for the entire site. Individual plot data will be provided and will include height, density, vigor, damage (if any), and survival. Planted woody stems will be marked annually, as needed, based off of a known origin so they can be found in succeeding monitoring years. Mortality will be determined from the difference between the baseline year's living planted stems and the current year's living planted stems. Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 3 -3 Section 4: MAINTENANCE AND CONTINGENCY PLAN Any identified high priority problem areas, such as streambank instability, aggradation /degradation, lack of vegetation establishment, or failure to meet hydrology success criteria will be evaluated on a case -by- case basis. The problem areas will be visually noted and remedial actions will be discussed with NCEEP staff to determine a plan of action. A remedial action plan will be submitted if maintenance is required. 4.1 Stream Stream problem areas will be mapped and included in the Current Condition Plan View (CCPV) as part of the annual stream assessment. Stream problems areas may include bank erosion, structure failure, beaver dams, aggradation /degradation, etc. Appropriate remedial actions will be determined with NCEEP correspondence. A proposal of work will be submitted if remediation of an area is required. 4.2 Vegetation Vegetative problem areas will be mapped and included in the CCPV as part of the annual vegetation assessment. Vegetation problems areas may include planted vegetation not meeting success criteria, persistent invasive species, barren areas with little to no herbaceous cover, or grass suffocation /crowding of planted stems. Appropriate remedial actions will be determined with NCEEP correspondence. A proposal of work will be submitted if remediation of an area is required. Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 4 -1 Section 5: AS -BUILT CONDITION (BASELINE) The Site construction and as -built surveys were completed between June 2014 and December 2014. The survey included developing an as -built topographic surface, locating the channel boundaries, structures, and cross - sections. For comparison purposes, the baseline monitoring divided the reach assessments in the same way they were established for design parameters: UT1 Reach 2, UT1 Reach 4, UT1 Reach 5, UT1A Reach 1, UT1A Reach 4, UT1B, and UT2. 5.1 As -Built /Record Drawings A half size baseline plan set is located in Appendix 4 with the post- construction survey and alignments for the project. A record drawing has also been provided to NCEEP as a separate document that redlines any significant field adjustments made during construction. Minimal adjustments were made during construction, where needed, based on field evaluation. 5.1.1 UT1 • Station 122 +83 logs replaced with boulder toe to avoid excavating into hill slope; • Station 143 +44 brush toe replaced with boulder toe to avoid impact to nearby trees; • Station 143 +64 log sill not installed due to existing boulder providing grade control; • Station 144 +31 boulder sill replaced with log sill due to onsite availability; • Station 147 +45 rock outlet added to prevent erosion from overland flow; • Station 151 +26 log sills replaced with boulder sills due to onsite availability; • Station 158 +26 boulder sill replaced with log sill due to onsite availability; and • Station 159 +00 boulder toe added to provide additional bank stability. 5.1.2 UT1A • Station 203 +17 brush toe replaced with boulder toe to avoid impacts to existing trees; • Station 210 +88 it was determined during construction that boulder toe was not necessary; and • Station 220 +06 log sill replaced with boulder sill due to onsite availability. 5.1.3 UT1B • No field adjustments were made during construction. 5.1.4 UT2 • No field adjustments were made during construction. 5.2 Baseline Data Assessment Baseline monitoring (MYO) was conducted between October 2014 and December 2014. The first annual monitoring assessment (MY1) will be completed in the fall of 2015. The streams will be monitored for a total of seven years, with the final monitoring activities concluding in 2021. The buffers will be monitored Agony Acres Mitigation Site Baseline Monitoring Document and As -Built Baseline Report -FINAL 5 -1 for a total of five years, with the final monitoring activities concluding in 2019. The close -out for the Agony Acres Mitigation Site will be conducted in 2022 given the success criteria has been met. As part of the closeout process, NCEEP will evaluate the Site at the end of the fourth year monitoring period to determine whether or not the Site is eligible to closeout following monitoring year five. If the Site is meeting success criteria, NCEEP will propose to the Interagency Review Team (IRT) to proceed with the closeout process. If the Site is not meeting success criteria, then an additional two years of monitoring will be conducted by Wildlands. 5.2.1 Morphological State of the Channel Morphological data for the as -built profile was collected between October 2014 and December 2014. Please refer to Appendix 2 for summary data tables, morphological plots, and stream photographs. Profile The MYO profiles closely match the profile design parameters. On the design profiles, riffles were depicted as straight lines with consistent slopes. However, at some locations on the as -built survey riffle profiles are not consistent in slope due to rock and log riffle features installed during construction for habitat variability. The as -built profile reflects the installation of log and rock sills with micro -pools interspersed in the riffle. The plotted longitudinal profiles and related summary data can be found in Appendix 2. Dimension The MYO dimension numbers closely match the design parameters with some minor variability for all reaches. Summary data and cross - section plots of each project reach can be found in Appendix 2. Pattern The MYO pattern metrics fell within the design parameters for all seven reaches. No major design changes were made to alignments during construction. Pattern data will be evaluated in monitoring year five if there are any indicators through the profile or dimensions that significant geomorphic adjustments have occurred. Sediment Transport As -built shear stresses and velocities are similar to design calculations and should reduce the risk of further erosion along all restoration reaches. The as -built condition for each of these reaches indicates an overall increase in substrate particle size (Table 5a — 5d). The substrate data for each constructed reach was compared to the design shear stress parameters from the mitigation plan to assess the potential for bed degradation. The shear stresses calculated for the constructed channels are within the allowable range, which indicates the channel is not at risk to trend toward channel degradation. Although a few streams have smaller particle sizes than were designed for, this is not a concern. The riffles were constructed with rock material mined on the Site which contained a greater variation in substrate size than material that has been subjected to flushing flows within an active stream channel. The streams had very little flow during construction, and there was minimal rainfall between completion of construction and baseline monitoring assessment. Once the streams reach baseflow and a few rain events occur, most of this smaller sediment should flush out of the riffles and into the pools. During monitoring year one (MY1) it is fully expected that the riffles will show a larger particle size than what was observed at baseline monitoring. 5.2.2 Vegetation The MYO vegetation survey was complete in January 2015. The MYO planted density is 650 stems /acre, which exceeds the MY5 density requirement. Summary data and photographs of each plot can be found in Appendix 3.
