The remaining gauges recorded hydroperiods of two and five percent of the growing season. On -site rainfall data is slightly below normal limits January through August 2010. The Smithfield gauge recorded rainfall totals that are below average but within normal limits for the same time period. Based on the results from the mitigation Site monitoring gauges during Years 1 through 5, the site has achieved the success criteria specified in the Restoration Plan. 4.0 VEGETATION 4.1 VEGETATION SUCCESS CRITERIA The interim measure of vegetative success for the Cox Wetland RestorationPlan is the survival of at least 320 three -year old planted trees per acre at the end of Year 3 of the monitoring period. The final vegetative success criteria is the survival of 260 five -year old planted trees per acre at the end of Year 5 of the monitoring period. 12 December 2010 Cox Mitigation Site FINAL Annual Monitoring Report for 2010 (Year 5) Up to 20 percent of the Site species composition may be comprised of invasive species (i e loblolly pine, red maple, sweet gum, etc ) Remedial action may be required should these present a problem and exceed 20 percent composition 42 DESCRIPTION OF SPECIES AND VEGETATION MONITORING The following monitoring protocol was designed to monitor vegetation survival 22 plots were established on the Cox Mitigation Site to monitor approximately 1 2 percent of the site (Figures 3a and 3b) Fifteen of the plots are established next to the stream bed to monitor the vegetation in the stream restoration buffer and riverme wetland zone The other seven plots are randomly located to represent the non - riverine wetland zone on the Site Plots have metal fence posts at each of the four corners to clearly and permanently establish the area to be sampled Ropes are hung connecting all four corners to help determinie if trees close to the plot boundary are inside or outside of the plot Trees on the boundary, and trees dust outside of the boundary that appear to have greater than 50 percent of their canopy inside the boundary are counted inside the plot A piece of ten - foot -tall white PVC pipe is placed over the metal post on one corner to facilitate visual location of the plot throughout the five -year monitoring period All of the planted stems inside the plot are flagged with orange flagging, and marked with a three - foot -tall piece of half -inch PVC to identify them as the planted stems (vs any colonizers), and to help locate them in the future Each stem is tagged with a permanent, numbered, aluminum tag Table 6 identifies the planted tree species Table 6 Planted Tree Species ID Scientific Name Common Name FAC Status 1 Quercus

MONITORING The vegetation monitoring documented a surviving tree stem density range of 440 to 800 stems per acre with an overall average density of 591 stems per acre The Site had earlier met the initial vegetation survival criteria of 320 stems per acre surviving after the third growing season, and has now met the final vegetation survival criteria of 260 stems per acre surviving after the fifth growing season Table 7 presents stem counts for each of the monitoring plots Each planted tree species is identified across the top row, and each plot is identified down the left column The

(Laquadambar styraciva) is the most common volunteer, though red maple (Acer 14 December 2010 Cox Mitigation Site FINAL Annual Monitoring Report for 2010 (Year 5) rubrum) and loblolly pine (Pmus taeda) were also observed These areas are overpopulated with mvasives due to the presence of seed trees in close proximity, as this is the narrowest part of the Site 44 VEGETATION OBSERVATIONS & CONCLUSIONS After construction of the mitigation Site, a permanent ground cover seed mixture of Virginia wild rye (Elymus virginicus), switch grass (Panicum virgatum), and fox sedge (Carex vulpinoidea) was broadcast on the site at a rate of 10 pounds per acre These species are present on the site Hydrophytic herbaceous vegetation, including rush (Juncus effusus), spike -rush (Eleocharis obtusa), boxseed (Ludwigia sp ), sedge (Carex spp ), smartweed (Polygonum spp ), and woolgrass (Scirpus cypermus) were observed across the site, particularly in areas of periodic inundation The presence of these herbaceous wetland plants helps to confirm the presence of wetland hydrology on the Site A number of weedy species occur on the Site, though none seem to pose any problems for the woody or herbaceous hydrophytic vegetation Common weedy vegetation includes ragweed (Ambrosia artemisufolia), wild dill (Foeniculum vulgare), goldenrod (Solidago spp ), dogfennel (Eupatorium capillhfolium) horseweed (Conyza spp ), and broomsedge (Andropogon spp ) The Site was planted in costal plain small stream swamp and wet hardwood forest species in January 2006 Twenty-two vegetation - monitoring plots were established throughout the planting areas The data reflects that the site had earlier met the interim minimum success criteria of 320 trees per acre at the end of year three, and has now met the final success criteria of 260 trees per acre at the end of year five 5 0 STREAM MONITORING 51 STREAM SUCCESS CRITERIA As stated in the approved Restoration Plan, the stream restoration success criteria for the Site includes the following • Bankfull Events Two bankfull flow events must be documented within the five year monitoring period • Cross - sections There should be little change in as -built cross sections Cross sections shall be classified using the Rosgen stream classification method, and all monitored cross sections should fall within the quantitative parameters defined for "E" or "C" type channels • Longitudinal Profiles The longitudinal profiles should show that the bedform features are remaining stable, e g they are not aggradmg or degrading Bedforms observed should be consistent with those observed in "E" and "C" type channels • Photo Reference Stations Photographs will be used to subjectively evaluate channel aggradation or degradation, bank erosion, success of riparian vegetation, and effectiveness of erosion control measures 52 STREAM MORPHOLOGY MONITORING PLAN To document the stated success criteria, the monitoring program described in the following sections was instituted following construction completion on the Cox Site 15 December 2010 Cox Mitigation Site FINAL Annual Monitoring Report for 2010 (Year S) 5 2 1 Cross Sections Two permanent cross sections were installed per 1 000 linear feet of stream restoration work, with one of the locations being a riffle cross section, and one location being a pool cross section A total of 16 permanent cross sections were established across the mitigation site (Figures 3a and 3b) Each cross section was marked on both banks with permanent pins to establish the exact transect used Permanent cross section pins were surveyed and located relative to a common benchmark to facilitate easy comparison of year -to -year data The annual cross section surveys include points measured at all breaks in slope, including top of bank, bankfull, inner berm, edge of water, and thalweg Riffle cross sections are classified using the Rosgen stream classification system Permanent cross sections for 2010 (Year 5) were surveyed in July 2010 5 2 2 Longitudinal Profile A longitudinal profile of approximately 3,000 feet was surveyed along the restoration reach in Years 1, 3, and 5 Measurements include thalweg, water surface, bankfull, and top of low bank Each of these measurements is taken at the head of each feature (e g riffle, run, pool, glide) and at the maximum pool depth A common benchmark will be used each year to facilitate comparison of year -to -year data 5 2 3 Hydrology A crest gauge was installed on the site to document bankfull events (Figure 3) The gauge is checked monthly, and records the highest out -of -bank flow event that occurred during the past month (Table 10) 5 2 4 Photo Reference Stations Photographs are used to visually document restoration success Reference stations are marked with wooden stakes, and Global Positioning Satellite (GPS) coordinates have been determined for each location Reference photos are taken at each permanent cross section from both stream banks, as well as facing upstream and downstream in the channel The survey tape is centered in the photographs of the bank and the water line is located in the lower edge of the frame with as much of the bank as possible included in each photo In- stream structures (e g , rock vanes, cross vanes, and constructed nffles) are also photographed Photo reference stations will be photographed at least once per year for at least five years following construction 53 STREAM MORPHOLOGY MONITORING RESULTS Photographs were taken throughout the monitoring season to document the evolution of the restored stream channel (Appendix D) Herbaceous vegetation is moderately dense along the restored stream Pools have maintained a variety of depths and habitat qualities, depending on the location and type of scour features (logs, root wads, transplants, etc ) In- stream structures installed within the restored stream included constructed riffles, log vanes, log weirs, and root wads Visual observations of structures throughout the 2010 growing season indicated that most of the structures are stable and functioning properly Vegetation has stabilized several areas of bank erosion and end cutting that were observed in previous monitoring years Minor erosion is still occurring at a few structures, and several mid- channel bars were noted Table 9 details the stream areas of concern 5 3 1 Cross Sections Year 5 cross section monitoring data for stream stability were collected during July 2010, and compared to baseline data collected in 2006 (Appendix B) All monitored cross sections fell 16 December 2010 Cox Mitigation Site FINAL Annual Monitoring Report for 2010 (Year 5) within the quantitative parameters defined for "E" or "C" type channels The cross section data are summarized in Table 11 5 3 2 Longitudinal Profile A longitudinal profile survey was conducted in Year 5 Based on a comparison to the previous profiles and cross sections, there has been little adjustment to the stream profile or dimension since construction Stream observation areas are listed in Table 9, and their locations are shown in Figure 6 None of these areas threaten the overall stability of the stream system Table 9 Stream Observation Areas ea � STA Desc owRecommendation --- February 000 March Numober Root wads 24 +25 Minor erosion on right bank behind root wads, SOA 1 June
