Background A. Restoration Project Goals The location of this stream and wetlands restoration project is shown in figure AB-1 . The restoration reach lies within headwater catchments of Haw River Basin and is an unnamed tributary of Michael's Branch. This area of the upper Haw River Basin lies within the North Carolina Piedmont Physiographic Region. The drainage basin contributing to stream flow at the lower end of the proposed restoration site is approximately 207 acres or 0.33 square miles. In March of 2012 a NW27 404/401 Permit to restore original aquatic functions within the watershed reach traversing the property was obtained to restore to a natural watershed condition approximately 1,400 linear feet of an unnamed tributary to Michael's Branch (tributary of Back Creek, Haw River Basin; located near the intersection of Hwy 70 (Church Steet) and University Drive in western Burlington, NC and approximately 1 acre of riparian bottomland wetlands. The wetland work focussed on the re-establish and enhance the ecological and hydrological relationship between riparian wetlands (at the eastern end of the Family Tract) and stream flow within the floodplain bottomlands of a restoration corridor on the property to improve function and value of wetlands on the property. It also served to remove two —70 year old man-made dams and impoundments on the property that pose safety concerns. The restoration of stream and wetlands performed under this NW 27 permit was based on the original plan in the permit and resulted in 1335 linear feet of restoration and about .9 acres of wetlands. The as -built planform map with stations is shown in Figure AB-4. The map is based on in field triangulation with survey grade tape from established baselines during construction followed by verification with post construction retriangulation as well as by overlay of aerial photographs, and a drone -based orthometric mosaic of the site obtained June/July of 2018. p. 3 Section 2. Monitoring Protocol The monitoring for the wetland and stream restoration is on annual basis for a period of 5 years commencing at the date of completion of the final planting schedules within the various habitat zones. The basis of monitoring is this protocol and the submission of an As -built Document (this report) providing detailed information on all wetlands and stream restoration work. The monitoring and the As Built report is broken into three basic components: Stream Morpholigic Stability, Buffer and Wetland Plant Communities, and Wetland Hydrology. These are discussed below. Stream Morphologic Stability. For streams, this includes the constructed pattern, dimension and profile at locations in each of the three sub -reaches. The planform sheet show the location of all in stream structures, established photo stations, vegetation monitoring plots, and locations of cross sections. Photo stations are set up for up and down stream tie in points, representative meander and inflection zones, and locations where structures have been installed. Cross section and photo stations have permanent benchmarks and all grade elevations are tied to a common permanent benchmark. The areas of new wetland restoration is also demarkated on the As -Built Planform Map of Figure AB-4. Stream Bank (Riparian), Buffer and Wetland Vegetation Monitoring. For stream bank vegetation, newly established stream bank woody plants shall be monitored using either total stem counts or representative 50' long bank reaches of sample plots collocated at monitoring cross section locations along each bank. Survivorship shall be 80%. If representative plots are used, a semi -quantitative survey of the stream must be made for areas larger than 5' in length for poor plant development. If areas of failure are found, these areas must be mapped and counted in detail. For wetland plant communities, a yearly population survey of plantings is required to demonstrate survivorship on a plot -by -plot basis. Both Facultative and Obligate woody vegetation is to be demonstrated in all wetland monitoring plots. Survivorship shall be 320 trees or more per acre. For the Piedmont Bottomland Forest Habitat areas (that are to be planted with woody trees and shrubs 8' on center) native species of trees are to be counted each monitoring cycle and survivorship shall be 320 trees/acre or better. The monitoring plan community plots are shown on both Figures AB-4 and 7. Wetland Hydrology. The monitoring for wetlands hydrology is based on the early growing season monitoring of groundwater levels for five years between March 1' and May 30' and shall be implemented with automated water level recorders recording at a frequency of at least every 12 hours at no less than one sampling at each of the three mitigation areas. The recorders will be deployed in the Spring of 2019. Saturated conditions in the upper 12" needs to be demonstrated for at least 25 days after March 15" Alternatively, continuous shallow groundwater monitoring can be preformed and demonstrate saturated conditions for 12.5% of the growing season (200 days).

Fluvial Geomorphology a. Summary of Monitoring Results for Geomorphic Stability The monitoring of the restored stream's geomophic stability is composed of three elements: 1) comparison of photos taken in successive years from the established photostations, 2) comparison of surveyed cross section between the as -built conditions, and each of the successive 5 years of monitoring at the established representative cross sections for inflection and meander sections of the restored reach, and 3) comparison of a surveyed longitudinal profile between as -built conditions and each of the successive five years of monitoring. The stream bank and bed conditions as represented in the above section's 10 photos can be seen to shown fully vegetated and stable overbank, bank, and stream bed conditions. The following figure showing a comparison of surveyed cross sections between the as -built and year 1 monitoring conditions shows all sections stable with no significant departures from the as -built conditions for stream bank or bed conditions. A few minor areas in the overbank floodplain areas (between bankfull and 2xbankfull heights (e.g. Rosgen `floodprone' areas) show aggradation of floodplain due to deposition of sediment during overbank storm events. The dynamic conditions observed in these overbank areas were anticipated and serve to provide stability (via attenuation of shear stresses) and water quality benefits (via removal of clays and silts in saltation and suspended transport. The second following figure or exhibit shows a comparison of the surveyed longitudinal stream profile between the as -built and Year 1 monitoring conditions (stationing from lower tie in (station 00 ft) to the upper tie in at the Huffinan Lane box culvert ( — station 1350 ft). Again one observes that all the established sills that were constructed at the transitions from the restored streams inflection (riffle and runs) and meander pool reaches have maintained stable elevations. The only significant departures from the as -built conditions are found between sills with the development of deeper pools as storm flow dynamically adjusts the bed profile to achieve an equilibrium in the typical `channel -forming' bankfull flow event's bed shear stress. p. 12 w 620 South Cross—Section-1 North 616 0 � 610 m w 605 0 10 20 30 40 50 60 70 60 Distance [(t) 620 South Cross Section 92 North = 815 a 610 m w 605 0 10 20 30 40 50 60 70 80 Distance (ft) 820 South Cross Section #3 North � 615 0 610 m w 605 0 10 20 30 40 50 60 70 80 Distance (ft) 620 South Cross Section #4 North 615 0 > 61❑ m W 605 0 10 20 30 40 50 60 70 80 Distance (ft) 630 South Cross Section #5 North 625 0 � 620 m w 615 0 10 20 30 40 50 6o 70 80 Distance (ft) 630 South Cross .Section #6 North 625 0 620 m w 615 0 10 20 30 40 50 60 70 80 Distance ift) 630 South Cross Section #7 North 625 a 7 620 m w 615 0 10 20 30 40 50 60 70 80 Distance (ft) $30 South Cross Section 98 Now 625 a 620 m w 615 0 10 20 30 40 50 6❑ 70 80 Distance (ft) �.

Summary of Results Vegetative monitoring consists of surveying of vegetation along and within transects, plots and representative lengths of stream banks and then comparing the number (e.g. density) of living native herbaceous and woody plants on the species level. The asbuilt conditions are those documented in restoration schedule, and for each of the 5 successive monitoring events the botanist resurveys each of the established stations to quantitatively assess and document herbaceous and wood species that are present. The observations are broken up and documented for bottomland transects some of which are within the restored and enhance floodplain wetlands (NC Piedmont Swamp Forest) and the remained within the NC Piedmont Bottomland Forest, a small sample of lm x lm plots within these two types of communities to provide representative assessment of the understory herbaceous community, and then a table shown the density and species present as riparian woody bank vegetation. Each of these tabulated elements follow. Woody and herbaceous vegetation continues to flourish across the site. Trees per acre estimates range from a low of 1,042 for Transect #4 to 3,151 for Transect #3. The average for the 4 transects is 1,838. The stream is shaded for most of its length by Hazel alder (Alnus serrulata) and in other areas by Black willow (Salix nigra). Many trees are estimated to be 15 feet and more in height. Some Cottonswoods (Populus deltoides) are approximately 30 feet. Herbaceous growth is dense and varied. Jewelweed (Inpatiens capensis), Arrowleaf tearthumb (Polygonatum pensylvanicum), and Common rush (Juncus effusus) are found along the restored reach and are quite dense in places. Blackberry (Rubus sp.) is established up and down the reach and becoming fairly impenetrable. Ten woody species are commonly found as volunteers with Sycamore (Platnus occidentalis) being most abundantly found. Silk tree (Albizia julibrissin) is found in several places and may need to be removed. p. 15 b.

Monitoring of Wetland Hydrology a. Protocol: The monitoring protocol for determining the success of the wetland enhancement and restoration areas was stated in the asbuilt report to be based on recording waterlevels using `continuous' water level loggers from March 15 (leaf on) for a period of approximately 8 weeks at the start of the growing season, which is the period within which `seasonal' wetlands are anticipated to experience high water tables after last frost in North Carolina. However, due to transitions in the ownership of the restoration tract, the waterlevel loggers could not be installed to meet the March 15th deadline. Thus this data is not available for Year 1. The new owner (Venn University LLC) will purchase the require loggers and these are to be installed prior to March 15t" of 2020. Future data must demonstrate sufficiently high water tables for the remaining monitoring years. In lieu of having this water leval logging data for year 1, the wetland areas were assessed for their current waterlevels (Oct 11, 2019) by hand auger to a minimum depth of approximately 20 inches. The locations of the wetland auger holes are shown in the attached map, and the recorded water level observations tabulated in the following table. 2 of the eight auger holes had water levels in the upper 12 inches for a period within which seasonal wetlands are normally dry in the upper 12". At the current time the wetland hydrologic data does not suggest there will be a problem with meeting wetland hydrologic success criteria, but additional data is needed to demonstrate the success of the wetlands work. p. 21 al r i t rpf L. r , � r ILA "'ems -- � •" -�L __ � r S Heearn Resrom[wn PrajaCci .

Summary of Monitoring for Year I (ending September, 2019) a. Overall Year 1 Restoration Status. The photostations, cross sections and longitudinal profile all demonstrate that a stable, (equilibrium) stream has been successfully established across the valley bottom previously occupied by the two former ponds. There is one 40-45' section and a lower check dam 15-20 section that have not been restored due to actions yet to be completed under the allied NW39 permit for a road crossing (future Hillier Drive). Should that culvert crossing not be completed prior to the expiration of that permit, these two outliers shall be restored prior to the termination of the 5 year monitoring period for the NW27 permit. Vegetation is also well established within the restoration corridor. As noted above, one invasive species is going to be monitored and if compromises native populations/communiti3es shall be treated. Wetland hydrology needs to be further assessed (in accordance the above monitoring protocol) but the limited data gathered in the year 1 monitoring effort suggests that the bottomland wetlands will maintain st least seasonal high water table conditions. b. Contingency Plans. 1) Invasive species are to be carefully monitored during year 2. 2) If the NW 39 crossing is not completed the rip rap located in the lower check dam and future culvert crossing are to be removed, and bed and banks restored to the reference reach conditions. 3) Finally, prior to March 15t' of 2020 an array of water level loggers are to be installed within the bottomland wetlands to demonstrate at a minimum seasonal high water table conditions that meet jurisdictional wetland criteria for the NC Piedmont. c. Misc. Matters. The property owner prior to May of 2019, Hillier Keziah Family LLC, authorized HARP, Inc to represent them in the application for a permit (NW39) for impacts necessary to install a road crossing using a 48" culvert with up and down stream prefabricated concrete headwall assemblies and a maximum impact of 45' along the stream. The location of this road crossing is shown on the As -Built Planform in Figure AB-4. The verification was issued on April 13, 2017 and expires on March 18' of 2022.. During 2019 ownership of the restoration corridor and adjoining parcels under commercial development were transferred via a foreclosure process from Hillier Keziah Family LLC to Venn University LLC. The Managing Partner of Venn Univerisy LLC is Shawn Cummings. At the request of Mr. Cummings future monitoring shall be conducted under the supervision of Dr. Randall Forsythe, President of Terradigital, Inc. The year 1 monitoring was also completed under Dr. Forsythe's supervision, but under a subcontract arrangement with HARP, Inc. p. 24 F.
