The site is located approximately 1,500 feet south of the intersection of NC Highway 70 and NC Highway 581 in Wayne County, NC. See Figure 1. The site drains generally northeast to the Little River in the Neuse River Basin (03‐04‐06) (WS‐IV, NSW). The approved Buffer Restoration Plan calls for the site to be monitored for a total of five (5) consecutive years, with monitoring and reporting performed on an annual basis. This monitoring report provides data collected during Year Five (the final year) of the required five year monitoring period. 1.2 Project History As required by the February 2008 401 WQC and Major Variance Approval (DWQ Project No. 03‐0065), S&EC prepared the Highway 70 & 581 Buffer Restoration Plan in January 2013. This plan was subsequently approved by the NCDENR Division of Water Resources (DWR) on March 12, 2013. Planting bed preparation and buffer planting activities were performed by North State Environmental, Inc. of Winston‐Salem, NC between April 13 and 17, 2015. During this period, S&EC provided periodic construction observation, interpretation of construction documents and necessary contractor guidance including select field adjustments based on conditions encountered during construction. In May of 2015, S&EC submitted a modification request for the WQC, the Major Variance, and corresponding Buffer Restoration Plan to allow for minor modifications to the recorded buffer area boundaries. DWR approved the modification request on August 17, 2015. In October of 2015 the required Deed Restriction and Plat Map were recorded with the Wayne County, NC Register of Deeds. These documents, along with a legal description of the buffer restoration areas were prepared by McDavid Associates, Inc. of Farmville, NC. Copies of all these documents were provided to DWR. On March 15, 2018, at DWR’s request, supplemental site planting was performed by North State Environmental, Inc. Tree plantings, intended to augment select areas of marginal vegetative success, included the installation of a total of 50 each 1‐gallon potted River Birch, Tulip Poplar, Green Ash and American Sycamore. At that time a buffer seed mix, lime and fertilizer were applied to select areas within the buffer. Protective tree fencing was also installed to approximately 300 linear feet of the buffer boundary where adjacent site activities were in close proximity to the buffer area boundary. The Year Two monitoring report was prepared by S&EC and submitted to DWR via email on November 17, 2016. The Year Three monitoring report was prepared by S&EC and submitted to DWR via email on December 12, 2017. The Year Four monitoring report was prepared by S&EC and submitted to NCDWR via email on November 26, 2018. 2 2.0 SITE MONITORING 2.1 Monitoring Overview As described in the Buffer Restoration Plan, annual monitoring is required for a five (5) year duration or until DWR has determined success for the site. Annual monitoring reports are submitted to DWR by December 31st of each monitoring year. Annual reports are to include quantitative and qualitative monitoring results, a map showing the location of vegetation sample points and photo points, and a map showing any problem areas. Reports will also include recommendations for supplemental stabilization and planting as appropriate. The overall site survival rate and number of surviving planted stems per acre are calculated by averaging the survival rate of all of the sample points. The site will be deemed successful if the average survival rate of planted stems within the sample points is equal to or greater than the required density of 320 stems per acre at the end of the five year monitoring period, and success is confirmed by DWR. For further detail regarding site monitoring the interested reader is referred to the approved Buffer Restoration Plan. The annual monitoring site visit for Year Five was performed by S&EC on November 22, 2019. Monitoring consisted of traversing the length of the buffer restoration area for the purpose of observing and photo documenting the condition of the buffer and overall vegetative success. General site conditions as well as the survival of the supplemental plantings were also observed during this site visit. 2.2 Monitoring Components Monitoring Components including vegetation monitoring “sample points” and photo points were established at various locations as shown on the Site Monitoring Layout (Figure 2). 2.2.1 Vegetation Monitoring Plots A total of eight (8) vegetation sample points are located across the site within the restored buffer areas. Each sample point consists of a driven steel rebar and wooden stake locating the central point within the count area and 10 stems within the general vicinity of the stake. Sample points are sequentially numbered. Each specimen identified as a planted specimen was flagged and staked, and sequentially numbered so it can be counted during subsequent site monitoring visits. Each sample point encompasses an area of approximately 640 square feet (SF) (10 trees planted on 8‐foot by 8‐foot centers or 64 SF/tree). The total area included within all eight (8) sample points will be 5,120 SF, or approximately 5% of the total 2.45‐acre (106,722 SF) buffer restoration area. This exceeds the DWR requirement that 2% of the restoration area is sampled. 3 2.2.2 Buffer Photo Points Eight (8) buffer photo points are co‐located with the sample points to document the general condition of the site, including the staked vegetation plots, at the time of our site visit. Three supplemental buffer photo points were added in 2018 to photo document the supplemental planting performed in early 2018. See Figure 2. 4 3.0 SITE MONITORING RESULTS This section details the observations made during the Year Five monitoring visit with regard to vegetative monitoring and an evaluation of overall site restoration success. 3.1 Vegetative Monitoring & Site Stability Planted woody stems were counted at the eight (8) buffer vegetation sample points. Planted woody stem counts by species and by sample point are presented in the following table: The average number of surviving planted woody stems per sample point is 8.0 stems. A review of the sample plots reveals a current (2019 – Year Five) site cumulative live stem density of approximately 544 stems per acre. Three woody species remain out of the four that were originally represented. No areas of instability within the restored buffer areas were observed during our site visit. Please refer to Appendix B for representative photographs of each vegetation monitoring plot. The location of photo points are shown in Figure 2. Our monitoring results indicate that the average stem density for all the sample plots well exceed the required stem density of 320 stems per acre at the end of the five year monitoring period. In addition, the individual stem density of all 8 sample points also exceeds the require stem density of 320 stems per acre. As previously described during our monitoring site visit, we observed each of the 50 supplemental plantings (previously marked with pin flags) installed in the March of 2018. Our observations indicate that a total of 30 (60%) of the supplemental plantings have survived to date adding to the planting Woody Stems Year Five (2019) Sample Points Yearly Totals 1 2 3 4 5 6 7 8 River Birch (Betula nigra) 7 1 7 2 5 4 2 3 31 Green Ash (Fraxinus pennsylvanica) ‐‐ 4 1 4 ‐‐ ‐‐ ‐‐ 1 10 Tulip Poplar (Liriodendron tulipifera) ‐‐ 0 ‐‐ ‐‐ 0 0 ‐‐ 0 0 American Sycamore (Platanus occidentalis) 2 1 2 2 3 3 8 2 23 As‐built/Year One Totals 10 10 10 10 10 10 10 10 80 Year Five Totals 9 6 10 8 8 7 10 6 64 Plot Survival Rate 90% 60% 100% 80% 80% 70% 100% 60% 64% Plot Live Stem Density (stems/acre) 612 408 680 544 544 476 680 408 Site Average Live Stem Density Average of all sample points = 544 stems per acre 5 success. Photos of the supplemental planting areas taken during our site monitoring visit are provided in Appendix B. The location of the supplemental photo points are shown in Figure 2. 3.2 Monitoring Success – Year Five (2019) Based on the success of planted tree species and the observed stability of the buffer area, as well as the observed success of the supplemental plantings, it is our opinion that the site restoration efforts remain successful to this point. Observations made during the annual monitoring visit indicate that the Rosewood Industrial Park Buffer Restoration efforts are in compliance with the conditions 401 WQC and Major Variance Approval.
