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 conducted on an annual basis. This monitoring report provides data collected during Year Two 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. The year one monitoring report was similarly prepared by S&EC and submitted to DWR on December 29, 2015. 2.0 SITE MONITORING 2.1 Monitoring Overview As described in the Buffer Restoration Plan monitoring frequency will be annually for the required five (5) year duration or until DWR has determined success of the site. The annual monitoring report will be 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 it as appropriate. The overall site survival rate and number of surviving planted stems per acre will be 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 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 Two was performed by S&EC on October 5, 2016. 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. During the site visit, general site conditions were also observed. 2.2 Monitoring Components Monitoring Components including vegetation monitoring "sample points" (sample points) and photo points were established at various locations as shown on the attached Site Monitoring Layout. 2.2.1 Vegetation Monitoring Plots A total of eight (8) vegetation sample points are located across the site within restored buffer areas. See Figure 2. 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 centers or 64 SF/tree). The total area included within all 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. 2.2.2 Buffer Photo Points Eight (8) buffer photo points are located across the site to document the general condition of the site, including the staked vegetation plots, at the time of our site visit. 0 3.0 SITE MONITORING RESULTS This section details the observations made during the Year Two 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 live planted woody stems per sample point is 9.75 stems. The sample plot median is 10 stems. A review of the sample plots reveals a current (2016 — Year Two) site cumulative live stem density of approximately 663 stems per acre. Four (4) planted woody species are represented. Please refer to Appendix B for comparative photographs of each vegetation monitoring plot. No areas of instability within the restored buffer areas were observed during our site visit. 3.2 Monitoring Success — Year Two (2016) Based on the success of planted tree species and the observed stability of the buffer area, it is our opinion that the site restoration efforts are 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.

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.
