The project lies within a rural setting that includes agricultural, forested, and low- density residential areas. The project is located on Koopman Dairies (formerly Meredell Farm), a small farm operation that includes dairy and row crop production. Prior to restoration work, the project stream had been historically destabilized through channelization and hoof - shear. Baker Engineering designed the restoration plans and restoration was completed in 2008. SEPI Engineering & Construction (SEPI) began the stream and riparian monitoring for Meredell Farms in October 2013. The goal of the project is to restore and improve the stream channel and riparian buffer form and function on -site through the following objectives: • Restore 3,865 LF of channel dimension, pattern and profile. • Enhance 4,704 LF of channel dimension, and /or profile. • Preserve 5,136 LF of stream channel and riparian buffer. • Improve floodplain functionality by matching floodplain elevation with bankfull stage. • Establish native stream bank and floodplain vegetation in the permanent conservation easement. • Improve the water quality in the Upper Cape Fear River watershed by fencing cattle out of the stream and reducing bank erosion. SEPI performed stream and riparian monitoring in the fall of 2014 for this Year 7 Annual Monitoring Report. VEGETATION ASSESSMENT Vegetation monitoring in Year 7 included visual assessment of the riparian zone and buffer mitigation areas to update the Current Conditions Plan View (CCPV) and Carolina Vegetation Survey (CVS) assessment of 12 vegetation plots. SEPI observed areas of concern that based on visual assessment did not appear to be meeting riparian zone success criteria of 260 stems per acre after 7 years. These observed conditions are reflected in the CCPV figures (Figures 2 -9) within this report and briefly discussed below. • The conservation easement area surrounding stream reaches UT I, UT2, M1, and UT5 continue to have large areas that lack significant counts of visible planted woody stems. Treatments applied to areas where the easement was replanted seemed to have little effect on herbaceous cover. It was visually observed that the vegetation established within the buffer and outside of the bankfull bench area primarily consists of grasses and herbaceous species. Good vegetation growth was primarily observed within the bankfull bench area for each of these reaches. • The lower M1 area (downstream of the stream crossing) continues to have a significant invasive species population consisting of Chinese privet and cattails. • UT3 and UT4 also had instances of tree -of- heaven and Chinese privet throughout the reaches. • The site continues to be free of encroachments to the easement, although a portion of the fence at the stream crossing of UT5 has been damaged. Meredell Farm SEPI Engineering & Construction EEP Project #247 1 Annual Final Monitoring Report November 2014 Monitoring Year 7 of 7 Detailed data collected from the CVS assessment of the 12 vegetation plots can be found in Appendix C of this report. Ten of the 12 veg plots exceeded the riparian zone success criteria of 260 stems /acre after 7 years, and 4 of the 11 buffer vegetation plots exceeded the buffer mitigation success criteria of 320 stems /acre after 7 years. The total average planted stem density for all twelve veg plots is 425 stems /acre for Year 7 Monitoring. Invasive species continue to be treated on reaches UT I, UT2, UT3, UT4, and M1. The target species of concern includes Ailanthus altissima and Ligustrum sinense. Detailed maps on invasive species control efforts can be found in Appendix C. STREAM ASSESSMENT Year 7 stream channel monitoring included a visual assessment of the stream channel and in- stream structures to update the Current Conditions Plan View (CCPV) and collection of geomorphic profile data. Visual observations of the stream channel conditions were conducted to determine if the project is establishing toward the stream success criteria outlined in the approved Restoration Plan (2004). These goals are outlined below: • Longitudinal Profile: o "The longitudinal profile data should show that the bedform features are remaining stable and are not aggrading or degrading. The pools should remain deep with flat water surface slopes and the riffles should remain steep and shallow." The visual assessment and geomorphic data collection completed for the site indicated that approximately 95% of the project reaches were performing within established success criteria ranges. The remaining 5% were exhibiting impacts such as headcuts and stream structure instabilities. The observed stream channel conditions are reflected in the CCPV figures (Figures 2 -9) within this report and briefly discussed below. • Two instream structures (Stations M1: 303 +25 and 305 +00) had flow going between the sill and arm boulders, but no further instability was observed as a result of the conditions • Two log vanes and one rootwad (Stations M1: 303 +75, 314 +50, and 321 +00) had approximately 15% bank erosion • Six instances of headcut were observed on UT3, UT4, and UT5 • There continues to be a small area of concentrated overland runoff through the buffer on the UT3a near Station 10 +50, and on UT4 at Station 10 +00 that is causing erosion to the stream bank • Two areas of split channel flow were identified along the existing stream at the upstream and downstream section of UT5 Geomorphic monitoring included collection of 4 longitudinal profile segments. Channel profile stability assessment includes the entire restored length of the project. Survey monuments were not present in the field. Due to this and differences in surveying methodologies between monitoring year 5 and monitoring years 6 and 7, the longitudinal profile data may differ in some areas. It should also be noted that sections of reaches UT1 and Ml Lower indicate a one foot difference in thalweg elevations between MY06 and MY07. These areas were noted as stable during the field review. Therefore, it was concluded that these differences arose from difficulty obtaining accurate GPS signal under heavy canopy which resulted in greater distances between collected points along the thalweg. Refer to Appendix D contained herein for detailed results of the longitudinal profile data collection. Meredell Farm SEPI Engineering & Construction EEP Project #247 2 Annual Final Monitoring Report November 2014 Monitoring Year 7 of 7 SITE HYDROLOGY Year 7 hydrologic bankfull indicators were collected during monitoring field visits. These indicators include collection of visually observed wracklines at, or above, the bankfull elevation and recordation of the crest gauge height located at Station 307 +000 on reach M1. • Wracklines were noted above the bankfull bench and within the floodplain during the site assessment field visit conducted on October 1, 2014. A crest gauge reading of 1.08 feet was recorded during the annual monitoring field visit conducted on October 1, 2014. The baseline bankfull design maximum depth range for reach M1 is 1.0 foot (min) to 1.3 feet (max); therefore, the crest gauge reading indicates that a bankfull event had occurred onsite. Refer to photograph SP within Appendix E of this report. Summary information/data related to the occurrence of such things as beaver or encroachment, and statistics related to performance of various project and monitoring elements can be found in the tables and figures in the report appendices. Narrative background and supporting information formerly found in these reports can be found in the Baseline Monitoring Report (formerly Mitigation Plan) and in the Mitigation Plan (formerly the Restoration Plan) documents available on EEP's website. All raw data supporting the tables and figures in the appendices are available from EEP upon request. METHODOLOGY The following methods were utilized during the Year 7 monitoring for data collection and post - processing: • Geomorphic topographic data collections were performed in the field using a survey - grade GPS such that each survey point has three- dimensional coordinates, and is georeferenced (NAD83 -State Plane Feet — FIPS 3200). • Longitudinal stationing was developed using the as -built survey thalweg as a baseline. • The CVS Level 2 methodology was utilized for the vegetation plot data collection. • Permanent cross - sectional data was not required for this monitoring year. • Particle size distribution was not required for this monitoring year.

The intent here is to provide the readerlconsumer of resign and monitoring information with a good general sense of the extent of hydrologic containment in the preexisting and the rehabilitated states as well as comparisons to the reference distributions. ER and BHR have been addressed in prior submissions as a subsample (cross - sections as part of the design survey), however, these subsamples have often focused entirely on facilitating design without providing a thorough pre- construtum distribution of these parameters, leaving the readenconsumer with a sample that is weighted heavily on the stable sections of the reach. This means that the distributions for these parameters should include data from both the —section surveys and the longitudinal profile and in the case of ER, visual estimates. For example, the typical longitudinal profile permits sampling ofthe BHR at riffles beyond those subject to uoss- sections and therefore can be readily integrated and provide a more complete sample distribution for these parameters, thereby providing the dlstributlond —rage necessary to provide meaningful comparisons.

ER and BHR have been addressed in prior submissions as a subsample (cross - sections as part of the design survey), however, these subsamples have often focused entirely on facilitating design without providing a thorough pre- construtum distribution of these parameters, leaving the readenconsumer with a sample that is weighted heavily on the stable sections of the reach. This means that the distributions for these parameters should include data from both the —section surveys and the longitudinal profile and in the case of ER, visual estimates. For example, the typical longitudinal profile permits sampling ofthe BHR at riffles beyond those subject to uoss- sections and therefore can be readily integrated and provide a more complete sample distribution for these parameters, thereby providing the dlstributlond —rage necessary to provide meaningful comparisons.
