Stream Morphological Data Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract Year 1 Annual Monitoring Report (April 2016) 1.0 EXECUTIVE SUMMARY LCFUMB LLC (Bank Sponsor), has completed Year 1 annual monitoring of the White Springs Tract of the Lower Cape Fear Umbrella Mitigation Bank. The White Springs Tract encompasses 72 acres, including 66.1 acres of non -riparian (i.e. pocosin and wet pine savanna) wetland restoration and 1.8 acres of riparian wetland restoration (small stream swamp). In addition, 1,312 If of first -order stream channel has been restored near the down -gradient section of the site. A total of 72 acres have been placed into a perpetual conservation easement for the long-term protection of the site. Restoration activities included Priority II restoration of the first order single -thread stream channel. Upstream of the first -order stream restoration, the existing, incised channel was widened, and its bed elevation raised. Lateral ditches that flowed into the channel (including both the first -order stream and the ditch upstream) were backfilled with spoil from the channel work and plugged with clay material. The restored riparian wetland valley associated with the restored first -order stream was planted with characteristic wetland trees. All restoration work (including earthwork and plantings) was completed in April 2015. (Refer to the As -Built Report submitted June 2015 for more detailed information regarding the implementation of the White Springs Tract). Per the approved restoration plan, monitoring of the site includes the assessment of both hydrologic and vegetative conditions over the course of a seven-year monitoring period. Following the completion of the earthwork, a total of three (3) 0.05 acre plots were established in the riparian wetland planted area. A total of eleven (11) shallow groundwater monitoring wells were installed throughout the site (including 2 gauges within the first -order stream channel). Hydrologic monitoring was conducted from April through the remainder of the year (through December 31, 2015). The annual vegetation monitoring was conducted in November 2015. Based upon the data collected, planted areas exhibit a high rate of survivorship of characteristic wetland tree seedlings. The hydrologic response to restoration efforts is also evident via groundwater and surface water data collected. Hydrologic residency times have been increased, and wetland hydroperiods have been re- established across the majority of the site. Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract Year 1 Annual Monitoring Report (April 2016) 2.0 PROJECT OVERVIEW A. Introduction Construction of the White Springs Tract (72 acre project area) portion of the Lower Cape Fear Umbrella Mitigation Bank was initiated in February 2015. The tract is located east of NC Hwy 133 (River Road SE) and immediately north of the Military Ocean Terminal at Sunny Point (MOTSU) Access Road approximately 4 miles north of Southport, NC (Figure 1). The site boundary is depicted in Figure 2.1 The project includes approximately 66.1 acres of non -riparian (i.e. pocosin and wet pine savanna) wetland restoration, 1.8 acres of riparian (small stream swamp) wetland restoration, and 1,312 linear feet of first -order stream restoration. Restoration activities included earthwork (back -filling lateral ditches, installing reinforced clay plugs, and the Priority II restoration of the first order single - thread stream channel); raising and widening the incised channel above the first -order stream; planting of characteristic riparian wetland vegetation; and the installation of monitoring devices. The White Springs portion of the Lower Cape Fear Umbrella Mitigation Bank is intended to provide suitable, high- quality wetland mitigation for authorized impacts within the Lower Cape Fear River Basin (Cataloging Unit 03030005). B. Mitigation Goals and Objectives The objective of the White Springs restoration project is to provide for the functional restoration and ecological up -lift of wetland and stream habitat via the re-establishment of characteristic hydrologic conditions and vegetative assemblages. It is anticipated that a number of key wetland functions and values will be restored including floodwater retention/abatement, sediment retention, nutrient transformation, and increased habitat connectivity. The project offers the unique opportunity to restore a wetland complex that includes a first -order single thread stream, riparian small -stream swamp, non - riparian pocosin, and non -riparian pine savanna. C. Project Implementation Restoration activities were initiated in February 2015. Restoration work included Priority II restoration of the first order single -thread stream channel. Upstream of the first -order stream restoration, the ' Note that a conservation easement for the property was recorded and conveyed to the Land Trust for America. The recorded conservation easement plat was submitted with the Mitigation Banking Instrument. Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract 2 Year 1 Annual Monitoring Report (April 2016) existing, incised channel was widened, and its bed elevation raised. Grading work (including the removal of spoil piles) along this segment of the reach has resulted in the establishment of a low flow valley contiguous with restored first order reach. Lateral ditches that flowed into the channel (including both the first -order stream and the ditch upstream) were backfilled with spoil from the channel work and plugged with clay material. Backfilling of ditches and the primary outlet canal in conjunction with the restoration of the stream channel is intended to restore characteristic wetland hydroperiods for non -riparian wetlands of the site. Planting of the restored riparian wetland valley associated with the restored first -order stream was conducted by Land Management Group, Inc. in April 2014. Plant material was provided by South Carolina SuperTree Nursery (Blenheim, SC). Bald cypress (Taxodium distichum) were planted in the valley bottom while Atlantic white cedar (Chamaecyparis thyoides) were planted on the valley slopes. A total of 3,000 seedlings were planted across the 1.8 acre riparian wetland restoration area. As part of the implementation of the restoration plan, LMG installed a total of eleven (11) automated shallow groundwater monitoring wells (RDS, Inc. WM-40s) within the 67.9 -ac restoration area (Figure 3A). The number of monitoring wells installed was proportional to the area of each community type. Per the restoration plan, seven (7) wells were installed in pocosin, two (2) wells were installed in pine savanna, and two (2) wells were installed in riparian wetlands. These wells were installed on March 26 and April 14 (2015). In addition, a total of three (3) automated wells have been installed within the identified non -riparian reference wetland area immediately east of the mitigation site (Figure 3A). Data from the reference wells will be used for comparative analyses to evaluate the hydrology of the wetland restoration areas. In addition to the groundwater monitoring wells, two (2) stream gauges were installed in the restored first -order stream channel (Figure 3B). These gauges will document bankfull events. The stream gauges were installed on March 26, 2015 (SG2) and April 14, 2015 (SG1). Three (3) permanent 0.05 -ac vegetation plots were randomly established within the 1.8 -ac riparian wetland restoration area. The four (4) corners of each plot are marked with rebar and flagged PVC. GPS coordinates are provided in Figure 3B. The number of wells and vegetation plots by community type are provided in Table 1. Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract 3 Year 1 Annual Monitoring Report (April 2016) Table 1.

Wetland Restoration Annual monitoring is being conducted near the end of each growing season for a period of seven years. This monitoring includes both a vegetative and hydrologic component per the approved restoration plan. The vegetative component includes an assessment of the conditions within each of the three 0.05 -ac permanent monitoring plots that have been established in the riparian wetland restoration area. Hydrologic monitoring is being conducted via the 11 wells installed throughout the wetland restoration areas. The following are the specific success criteria for both the vegetation and hydrologic monitoring of the wetland restoration areas. (1) Demonstrated density of planted species to meet or exceed 210 trees per acre at the end of 7 years (post -planting). (2) No single volunteer species (most notably, red maple, loblolly pine, and sweet gum) will comprise more than 50% of the total composition at year 2 or 3. If this occurs, remedial procedures will be implemented. During years 4 &5, no single volunteer species, comprising Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract 4 Year 1 Annual Monitoring Report (April 2016) over 50% of the total composition, may be more than half the height of the planted trees. If this occurs, remedial procedures will be implemented. (3) The hydrologic criterion is premised on the specific community type to be restored. (a) For the riparian small stream swamp community, the hydrologic criterion will be the establishment of a static water table at, or within, 12" of the soil surface for 12% of the growing season (equivalent to 36 days based upon a growing season between February 1st and November 30th)2 during periods of normal precipitation conditions. (b) For the non -riparian pocosin community, the hydrologic criterion will be the establishment of a static water table at, or within, 12" of the soil surface for 10% of the growing season (equivalent to 30 days based upon a growing season between February 1st and November 301h)2 during periods of normal precipitation conditions. (c) For the non -riparian pine savanna community, the hydrologic criterion will be the establishment of a static water table at, or within, 12" of the soil surface for 7% of the growing season (equivalent to 21 days based upon a growing season between February 1st and November 301h)2 during periods of normal precipitation conditions. B. Stream Restoration The primary success criteria for the First Order Stream are: Documentation of 2 bankfull events using techniques discussed below within a normal rainfall year in 3 of the 5 years of monitoring. Additional monitoring may be necessary in the event of abnormal climatic conditions. Level 1 Monitoring will be employed as detailed in the Stream Mitigation Guidelines, April 2003. Monitoring will occur every year for the five year monitoring period. Monitoring reports will be prepared each monitoring year and will include a discussion of any deviations and whether they are indicative of a stabilizing or destabilizing situation. Level 1 Monitoring includes the following: 2 Growing season based upon direction of IRT. Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract Year 1 Annual Monitoring Report (April 2016) (1) Photo -Documentation Extensive photo documentation is included in the stream monitoring phase of this project. Photos will be taken at all permanent cross-sections on a bi-annual basis (winter and summer) in addition to any problem areas that may develop after construction is completed. Photos will be georeferenced to the corresponding cross-section and/or problem area as part of the submitted report. Photo documentation will also be used to document the health of the riparian area plantings and the effectiveness of any erosion control measures. (2) Ecological Function The health of the riparian vegetation will be documented as part of the wetland restoration monitoring efforts. Three 0.05 -acre permanent monitoring plots have been established throughout the riparian wetland restoration including areas directly adjacent to the restored channel. The success criteria for wetland restoration are provided in Section 3A above. (3) Channel Stability/Survey Procedures a. Cross -Sections (First Order Channel) The White Springs Tract includes the restoration of 1,312 If of first order Coastal Plain stream. The restoration mimics low gradient, low velocity stream reaches characteristic of the outer Coastal Plain. No hardened materials (i.e. rock structures) were used. Rather, natural materials (such as root wads and log vanes) will assist with channel stabilization and grade control. Given the size, uniform design, and gentle slope (0.36%) of the project, four permanent cross-sections have been established on approximate 330 -ft intervals of stream length. Placement of these stations has been designed to assess the performance of potential problem areas (e.g. severe erosion, structural failure, etc.). These stations are also distributed between riffles and pools (two in riffles and two in pools) throughout the project. Refer to Figure 313 depicting the approximate location of the cross-sections. b. Longitudinal Profiles (First Order Channel) Given the length of the restored channel (1,312 If), a longitudinal profile of the entire restored reach will be performed. Data presented in the annual monitoring reports will be shown in comparison to as -built conditions. Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract 6 Year 1 Annual Monitoring Report (April 2016) c. Stream Flow Monitoring (First Order Channel) Documentation of stream flow within the project will also be conducted. Following stream construction activities, two (2) stream gauges were installed (Figure 313). These gauges will measure the elevation of water in the channel on an hourly basis and will be used to determine the cross-sectional area of the channel under a variety of flow conditions. 4.0 MONITORING RESULTS (YEAR 1) A. Vegetation Monitoring A total of 104 planted stems were enumerated throughout the three 0.05 -ac plots. For planted species, the total number of stems identified corresponds to an average density of 700 stems per acre (35 stems per 0.05 -ac plot) within the riparian wetland restoration area (Table 3). All of the plots exceeded the Year 7 minimum of 11 stems. As indicated above, bald cypress were planted in the valley bottom while Atlantic white cedar were planted on the valley slopes. Therefore, bald cypress is the only planted species in the vegetation monitoring plots. Several woody volunteers, including inkberry (Ilex glabra), fetterbush (Lyonia lucida), and redbay (Persea borbonia) were identified throughout the riparian wetland corridor. The presence of these desirable volunteer species has contributed increased diversity and is indicative of the targeted wetland community type. Refer to Appendix A for photographs of current site conditions. A comprehensive plot data table is provided in Appendix B. Table 2. Vegetation Data by Plot3 3 Plots are 0.05 -acre in size (20m X 10m).

Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract 7 Year 1 Annual Monitoring Report (April 2016) B. Hydrologic Monitoring (Wetlands) As indicated above, a total of thirteen (13) hydrologic monitoring wells/gauges were installed throughout the site on March 26 and April 14 (upon completion of all restoration work). Of these thirteen (13) wells/gauges, eleven (11) wells are located within the restored wetland areas. The number of wells installed within each restoration community type (pocosin, wet pine savanna, and riparian small stream swamp) is proportional to the acreage of each community type. 1. Summary of Precipitation Regional drought indices, including the Palmer Drought Index and the North Carolina Division of Water Resources (DWR) Drought Status Maps, were examined to interpret precipitation patterns and predicted subsurface water storage conditions relative to long-term climatic data. In particular, the Palmer Hydrological Drought Index maps depict hydrological (long-term cumulative) drought and wet conditions, which more accurately reflect groundwater conditions. Based upon the 2015 index maps, the Brunswick County area of North Carolina exhibited normal groundwater conditions on a monthly basis during January and March through September. The area was considered to be moderately moist in January and October and very moist in November and December. The Palmer Hydrologic Drought Index maps for 2015 are included in Appendix C. The NC Drought Status Monitoring Program compares existing data to long-term (1965-2013) climatic conditions for well data, stream baseflow data, and combined well and baseflow data. Contoured percentile data (30th/70th percentiles) are graphically displayed on monthly drought images. Based upon these maps, subsurface storage (i.e. groundwater) conditions were considered normal during April and July through September. Subsurface storage conditions were considered above normal during January through March, May, June, and October through December. The NC DWR Drought Status Maps for 2015 are included in Appendix D. The nearest rain gauge (Brunswick County Airport - KSUT) documented variable rainfall conditions throughout the year. Local rainfall data beginning in April are included in the hydrographs in Appendix E (wells were installed between March 26 and April 14). Rainfall conditions were generally normal in April through mid-July and late September through early October. Rainfall conditions were below normal (<30th percentile) in late July through mid-September. Precipitation was generally above Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract g Year 1 Annual Monitoring Report (April 2016) normal (>70t" percentile) from early October through the remainder of the year. Total rainfall for the year was 53.68 inches. According to the WETS long-term climatic data, mean annual rainfall for Longwood, NC is 54.94 inches (with a 30% chance of having less than 50.86 inches of annual precipitation and a 30% chance of having more than 58.56 inches of annual precipitation). As a result, the 2015 calendar year is considered normal for precipitation based upon the data from the Brunswick County Airport (NC) CRONOS station. 2. Pocosin Within the areas targeted for pocosin restoration, six (6) of the seven (7) wells exhibited hydroperiods of greater than 10% of the growing season (the hydrologic success criterion for pocosin). All six (6) of these wells exhibited water tables within 12 inches of the soil surface for 67 consecutive days (September 25 through November 30) during the growing season (equivalent to 22.1 % of the growing season). The one well not meeting success criteria (Well #10) exhibited a water table within 12 inches of the soil surface for only 3 consecutive days during the growing season. Note that no data was collected during the early portion of the growing season (wells were installed between March 26 and April 14). With the exception of Well #10, hydroperiods of the pocosin restoration wells closely resemble the non -riparian reference wells. Refer to Table 3 for a summary of the hydrologic data for the pocosin restoration wells. Refer to Table 4 for a summary of the hydrologic data for the non - riparian reference wells. Hydrographs are provided in Appendix E. 3. Wet Pine Savanna Both of the two (2) wells in the wet pine savanna restoration areas exhibited hydroperiods greaterthan 7% of the growing season (the hydrologic success criterion for wet pine savanna). The observed mean length of the hydroperiod during the growing season (February 1 through November 30) for these wells was 61 days (equivalent to 20.1 % of the growing season). The observed hydroperiods ranged between 10.9% of the growing season (Well #11) and 29.0% of the growing season (Well #7). Refer to Table 5 for a summary of the hydrologic data for the wet pine savanna restoration wells. Refer to Table 4 for a summary of the hydrologic data for the non -riparian reference wells.

Small Stream Swamp Both of the two (2) wells in the small stream swamp restoration area exhibited hydroperiods greater than 12% of the growing season (the hydrologic success criterion for small stream swamp). Both wells exhibited water tables within 12" of the soil surface for 88 consecutive days during the growing season from September 4 through November 30 (equivalent to 29.0% of the growing season). Well #9 also exhibited a water table within 12" of the soil surface for 88 consecutive days from April 15 through July 11. Refer to Table 6 for a summary of the hydrologic data for the small stream swamp restoration wells. Hydrographs are provided in Appendix E. C. Stream Monitoring 1. Photo -Documentation Extensive photo documentation was implemented during Year 1 for the stream monitoring phase of this project. Site visits were conducted and photographs were taken at all permanent cross-sections and potential problem areas on several occasions during Year 1 monitoring. Photos were geo- referenced to the corresponding cross-section and potential problem area. Photo documentation was also used to document the health of the riparian area plantings and the effectiveness of erosion control measures. Refer to Appendix A for photographs of site conditions throughout Year 1 monitoring. 2. Ecological Function The health of the riparian vegetation was documented as part of the wetland restoration monitoring efforts. Three (3) 0.05 ac. permanent monitoring plots were established throughout the riparian wetland restoration area including areas directly adjacent to the restored channel. Reference the vegetation monitoring section for monitoring results. 3. Channel Stability/Survey Procedures (a.) Cross -Sections (First Order Channel) The Lower Cape Fear Umbrella Mitigation Bank has restored 1,312 If of Coastal Plain stream on the White Springs Tract. The restoration has mimicked low gradient, low velocity stream reaches characteristic of the outer Coastal Plain. No hardened materials (i.e. rock structures) were used.

Given the size, uniform design, and gentle slope (0.36%) of the project, cross-sections were established on approximate 330 -ft intervals of stream length (totaling 4 permanent stations). Placement of these stations was designed to assess the performance of potential problem areas (i.e. severe erosion, structural failure). These stations were also evenly distributed between riffles and pools throughout the project. Refer to Figure 313 for the locations of the cross-section monitoring stations. Year 1 cross-section surveys are provided in Appendix F. A dimensional morphology summary table comparing Year 1 data to as -built (baseline) data is also provided in Appendix F. Reference the As -Built Report for more detailed information regarding baseline conditions. (b.) Longitudinal Profile (First Order Channel) Given the length of the restored channel (1,312 If), a longitudinal profile of the entire restored reach was performed. The Year 1 longitudinal survey is provided in Appendix F. A stream survey data summary table comparing Year 1 data to as -built (baseline) data is also provided in Appendix F. Reference the As -Built Report for more detailed information regarding baseline conditions. (c.) Stream Flow Monitoring (First Order Channel) As indicated above, a total of two (2) gauges were installed within the stream channel to document bankfull events on an hourly basis. These gauges capture the upper and middle sections of the stream. Gauge SG1 was placed furthest up -gradient (third stream meander from source) in order to capture bankfull events at the head of the restored stream reach. Gauge SG2 is located approximately 600 feet further down the stream. Refer to Figure 3A for a map depicting the locations of these gauges. Surface water and flow were documented in each of the two (2) gauges over several periods during the monitoring year. The valley exhibits a gentle slope (0.36%) from the upper end to the lowest end. The amplitude of the surface water varied at each gauge. Gauge SG1 exhibited a bankfull event eight (8) times during the monitoring period. Gauge SG2 recorded four (4) bankfull events during the monitoring period. Both gauges exhibited bankfull events simultaneously during four (4) time periods (May 10-11, Oct 2, Oct 5-6, and Nov 3). The duration of each bankfull event ranged from several hours to two (2) consecutive days. The three- day antecedent rainfall recorded prior to bankfull events ranged from 0.46 inches to 10.77 inches. Refer to Table 7 for a summary of bankfull events during Year 1 monitoring. Hydrographs are included in Appendix E. Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract 14 Year 1 Annual Monitoring Report (April 2016) Hourly hydrographs are included for the dates where both stream gauges recorded overbank flooding. Flow was also observed during several monitoring events throughout the year. Photographs are provided in Appendix A. Table 7. Summary of Year 1 Bankfull Event Monitoring (2015) Gauge Number Total Number of Bankfull Events Longest Number of Consecutive Days During Bankfull Event Dates of Bankfull Event(s) 3 -Day Antecedent Rainfall (Inches) (Brunswick County Airport - KSUT) May 10-11 4.08 (through 5/10) Sep 25 2.97 (through 9/25) Oct 2-3 10.77 (through 10/3) Oct 5-6 8.31 (through 10/6) SG1 8 2 Oct 10 0.46 (through 10/10) Nov 3-4 4.24 (through 11/4) Nov 9 1.23 (through 11/9) Dec 29 1.69 (through 12/28) May 10-11 4.08 (through 5/10) Oct 2 3.77 (through 10/2) SG2 4 2 Oct 5-6 8.31 (through 10/6) Nov 3 2.12 (through 11/3) D. Contingency Measures Stream banks and in -stream structures (i.e. root wads, log vanes, etc.) were monitored for evidence of surface bank erosion (i.e. down -cutting) several times throughout the monitoring year. Some bank erosion was observed adjacent to the log vanes. These log vanes are located between the two downstream cross-sections (XS3 and XS4). Refer to the As -Built Report for more specific information regarding the location of these in - stream structures. The slope increases significantly in this portion of the stream. Therefore, some bank erosion is expected as the recently restored stream adjusts to dynamic equilibrium. However, bank stabilization contingency measures are recommended to reduce down -cutting during this early period of stream adjustment. Transplants of local riparian vegetation (i.e. fetterbush) will be planted on the stream bank slopes to provide a buffer during high flow events. Also as a result of higher velocity flow in this relatively steeper portion of the Lower Cape Fear Umbrella Mitigation Bank — White Springs Tract 15 Year 1 Annual Monitoring Report (April 2016) stream, some minor aggradation has been documented in the pool at the cross-section located furthest downstream (XS4). Based on comparisons of cross-section survey data between baseline and Year 1 monitoring, this aggradation appears to be relatively minor and does not appear to have any significant adverse effects on stream geomorphology or function. 5.0 CONCLUSION Hydrologic data confirm the re-establishment of hydrology characteristic of the target habitats across the vast majority of the site as a result of the earthwork completed during the early growing season. Removal of the large outlet canal in conjunction with the re -contouring of the first -order stream valley has resulted in the connection of headwater wetland areas to White Springs Creek. There has been a discernible hydrologic response indicating the restoration of key hydrologic functions relating to water storage and groundwater recharge within the system. Vegetation and hydrologic monitoring of the project area indicate that the site is progressing well during the first year following the implementation of the restoration activities. Vegetation data document high rates of survivorship among the planted species (x stem density = 700 stems per acre). No significant vegetation issues were noted. Overall, the site appears to be progressing well toward the targeted wetland community types. The restoration site is already providing key wetland functions via the reduction of sediment/nutrient runoff; increased nutrient retention/transformation; increased floodwater storage; and the enhancement and protection of wildlife habitat. The site will be continued to be monitored over the next six years (through Year 7), and the findings of such will be provided in subsequent annual monitoring reports for agency review and concurrence.
