Construction of this project necessitated the relocation of portions of two tributaries to Horsepen Creek, Main Tributary #2 (South) and Tributary A (North). The relocation of these stream reaches was completed in ' March 2011. The stream relocations were permitted through the U.S. Army Corps of Engineers (Action I.D. SAW 2007 - 03980) and the North Carolina Department of Environment and Natural ' Resources (DWQ Project #06 -0684) and required a Level 1 Stream Restoration Mitigation and Monitoring Plan for this project. This level of monitoring includes the establishment of photo ' reference sites, plant survival monitoring, and channel stability monitoring. IThe following end of second year survey was conducted to evaluate and document the conditions of the relocated stream channels and associated riparian plantings following two years after the completion of construction. This data will be compared to the As -Built survey which provided a baseline for these future monitoring events as well as the first year survey. Methods Photo Reference Sites ' Photographs were taken during: 1) Second Year Survey for Plant Survival on August 23, 2013 Stream banks and adjacent areas were photographed for visual comparison of plant survival and ' groundcover. 1 Second Year Monitoring Report: Plant Survival New Garden Road Widening Phase II Project No. P -3741 2 • VA \ � �t3 r aj "��. :A' NO yyy J �r 1, .� -wo ,A 4 -. �M�l r.

(USI) with the assistance of a scientist from Carolina Wetland Services, Inc. (CWS) on August 23, 2013 following two years after the installation of the new plantings. Vegetation monitoring plots were established on both sides of each tributary during the As -Built Survey. The corners of each monitoring plot were marked with PVC pipe during the As -Built Survey so that the same plots can be used as the monitoring efforts continue for the next several years. Monitoring plots extend from the stream edge to the furthest extent of planted area. A stem count of each species occurring within each monitoring plot was conducted. Results Photo Reference Sites As part of the Second Year survey for the project, all areas of the project were photo documented. Plantings were photographed for visual plant survival comparisons. Representative photographs of the monitoring plots are included in Photopage 1 (Appendix A). The locations and directions of each of these photographs are shown in Figure 3 (Page 4). As an aside, the same locations and directions were used for these photographs as those taken during the As -Built and First Year surveys. Plant Survival A total of eight vegetation monitoring plots were established during the As -Built survey. Four of these plots (Plots 1A, 2A, 3A and 4A) were established in areas that were planted with live stakes. The remaining four plots (Plots 1B, 2B, 3B and 4B) were established in areas that had been planted with containerized trees and shrubs. As part of the Second Year survey, plant survival within these monitoring plots was surveyed on August 23, 2013. Table 1 on page 5 summarizes the overall data and information for the vegetation monitoring plots for the As- Built, First Year, and Second Year surveys. zcn CD �o C� CD a� w � o a 5' t va Ei oa � CD w N CD 1-1 e-' CA C• w b `•t CD n eY z 0 b w 1 1 I 1 1 1 1 1 1 1 1 Second Year Monitoring Report: Plant Survival New Garden Road Widening Phase II Project No. P -3741 Table 1.

The locations of Plots 1B, 2B, 3B and 4B are shown in Figure 3 on page 4. Representative photographs of each of the monitoring plots are included in Photopage 1 (Appendix A). Table 3 on the next page summarizes the containerized plant survival for the As- Built, First Year, and Second Year surveys. Species stem counts for Plots 1B, 2B, 3B and 4B for the Second Year survey are included in Appendix A. 5 1 1 1 1 1 1 Second Year Monitoring Report: Plant Survival New Garden Road Widening Phase II Project No. P -3741 When Plot 3B was established during the As -Built survey, it was located such that it would fall outside of the existing sanitary sewer easement to the west. However, during the First Year and Second Year surveys it was noted that approximately half of Plot 3B had been routinely mowed and maintained as part of the existing sanitary sewer easement. Because of these maintenance activities, the groundcover and stem counts in Plot 3B are much lower when compared to the other vegetation monitoring plots.

The data in Table 1 on page 5 indicates that the overall 1 1 k 1 1 1 1 coverage has gone from 76% during the As -Built survey to 91% during the First Year survey to 99% during the Second Year survey. Additionally, plant survival of the trees and shrubs appears to be variable but overall remains fairly good. However, the plant survival of the live stakes is relatively low. Therefore, some consideration should be given to supplemental live stake plantings this winter. 1 Second Year Monitoring Report: Photo Documentation — Photopage 1 New Garden Road Widening Phase II Project No. P -3741 i 1 1 1 1 i Appendix A Photopage 1 — Vegetative Monitoring Photographs ' Vegetative Monitoring Plots — Stem Counts 1 1 1 1 1 1 1 ' Second Year Monitoring Report: Photo Documentation — Photopage 1 New Garden Road Widening Phase II Project No. P -3741 Photo lAl: View of Vegetation Monitoring Plot 1A, facing west Photo 1A2: View of Vegetation Monitoring Plot IA, facing southwest 8 Second Year Monitoring Report: Photo Documentation — Photopage 1 New Garden Road Widening Phase II Project No. P -3741 t: fit r !
