This maintenance record will be kept in a log in a known set location. Any deficient 13MP elements noted in the inspection will be corrected, repaired or replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and the removal efficiency of the BMP. Important maintenance procedures: — Immediately following construction of the stormwater wetland, bi-weekly inspections will be conducted and wetland plants will be watered bi-weekly until vegetation becomes established (commonly six weeks). — No portion of the stormwater wetland will be fertilized after the first initial fertilization that is required to establish the wetland plants. — Stable groundcover will be maintained in the drainage area to reduce the sediment load to the wetland. Once a year, a dam safety expert should inspect the embankment. After the stormwater wetland is established, I will inspect it monthly and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and maintenance will be kept in a known set location and will be available upon request. Inspection activities shall be performed as follows.

The existing undeveloped site is located on the north side of NC HWY 711 / Country Club Drive at the intersection with Pinecrest Circle. The post -development impervious area is approximately 0.99 acres (including future building and parking lot expansions) approximate 69% of site being impervious area. During construction all erosion control drainage will be treated by a skimmer sediment basin which will be converted into a constructed wetland area to treat all stormwater from proposed site. The stormwater wetland will provide an 85% reduction in total suspended soilds, 40% nitrogen reduction, and 40% phosphorus reduction for the first 1.0" of rainfall. The stormwater wetland will outlet via a proposed drainage swale across the adjacent 60'Access Easement to reach the existing ditch along the northeastern property line. A field study completed by S&ME, Inc., has determined the seasonal high water table elevation to be located at 24 inches below existing grade level, equating to approximate elevation +_134.00 in the region of the proposed wetland basin. Based on this evaluation, the permanent pool of the basin has been set at elevation 133.50.

(S&ME) has conducted a soil evaluation including Seasonal High Water Table (SHWT) estimation in general accordance with S&ME Proposal No. 1054-12-198 (CO-1) dated January, 2013. Our evaluation was conducted to provide information for the design of an appropriate stormwater Best Management Practice (BMP) device and a Stormwater Management Permit Application to the North Carolina Department of Environment and Natural Resources (NCDENR) — Division of Water Quality (DWQ). A soil scientist evaluated the soil conditions within the proposed stormwater BMP area. PROJECT BACKGROUND The subject site is located northeast of the intersection of NC Hwy 711 (Country Club Road) and Nigel Road (SR 1548) in Lumberton, Robeson County, North Carolina The site is depicted on the attached Vicinity Map (Figure 1) and Site Map (Figure 2). As a result of the proposed construction of the ECU Service Learning Center and associated parking lot area and impervious surface, a stormwater BMP is required to treat stormwater generated from the site to comply with State stormwater management requirements. Use of stormwater BMP's are subject to the suitability of site soils and regulatory approval. Regulatory guidance on requirements for permitting of stormwater BMP's are provided in the North Carolina Division of Water Quality — Stormwater Best Management Practices Manual (NCDENR-S W-BMP), dated July 2007 (Revised September, 2009). FINDINGS The soil evaluation was performed with hand auger borings at two locations within the proposed stormwater BMP area as shown on the attached Figure 3. Our evaluation consisted of identifying and recording the soil morphological conditions at this location in order to develop soil profile descriptions, which are also shown on the attached Figure 3. S&ME, INC. / 3201 Spring Forest Road / Raleigh, NC 27616 1 p 919,872.2660 / 919.876.3958 / w .smeinc.com Soil Evaluation for Stormwater BMP SBME Job No. 1054-12-198 ECU Service Learning Center, Lumberton, Robeson Co., North Carolina March 20, 2013 Permeability/Hydraulic Conductivity Estimation Under current North Carolina Division of Water Quality (NCDWQ) requirements for various stormwater devices, the in -situ soil permeability/conductivity is an important design factor. Therefore, the soil profile descriptions on the attached map (Figure 3) show the soil morphological conditions including texture, estimated United States Department of Agriculture (USDA) permeability and estimated USDA hydraulic conductivity (KSAT) for the different soil horizons found on -site. In the area of both Boring Location B-1 and B-2 within the proposed stormwater BMP area, the soil surface layer consisted of sandy loam material which has an estimated USDA permeability range of 2 to 6 inches/hour and USDA estimated Ksat range of 1.4 to 14 inches per hour. The underlying soil material consisted of sandy clay loam which has an estimated USDA permeability range of 0.6 to 2 inches/hour and USDA estimated Ksat range of 0.14 to 1.4 inches per hour. Please refer to the enclosed map and soil profile descriptions, for more information. These estimates were obtained from one or more of the following: Robeson County Soil Survey "Physical & Chemical Properties of the Soil - Permeability"; and/or USDA-NRCS (United States Department of Agriculture - Natural Resource Conservation Service) official series description, and/or "NRCS Field Book for Describing & Sampling Soils" the permeability estimates were converted to conductivity on the profile description tables. SHWT Estimation Under current NCDWQ regulations, the depth of various stormwater BMP devices from the SHWT is an important design consideration. Therefore, S&ME evaluated the SHWT by advancing hand auger borings and evaluating the soil for evidence of SHWT influence. This evaluation involved looking at the, actual moisture content in the soil and observing the matrix and mottle colors. Depending on the soil texture, the soil color will indicate processes that are driven by SHWT fluctuations, such as iron reduction and oxidation and organic matter staining. See Table 1 and the soil profile descriptions on Figure 3 for the estimated SHWT depths based on soil color. Table 1: SHWT Information Lo 117061,ti: Inches;beloW;Exlstin ,Grow diLevel B-1 22 B-2 24 CONCLUSION The SHWT depths encountered within the proposed stormwater BMP area were 22 inches and 24 inches from existing ground level (EGL) respectively. Therefore, if a wet detention basin is proposed, the permanent pool elevation should be 16 to 28 inches (+/- 6 inches from most Soil Evaluation for Stonnwater BMP SBME Job No. 1054-12-198 ECU Service Learning Center, Lumberton, Robeson Co., North Carolina March 20, 2013 limiting SHWT) below the natural ground level in the area evaluated. Also, current regulations for wet detention basins state that if a liner is required, it must be constructed or compacted such that the infiltration rate is no more than 0.01 inches per hour. Neither Boring Location B-1 nor B-2 within the proposed stormwater BMP device area had soil with estimated permeability /infiltration rates conducive for use as a clay liner, so a synthetic clay liner would most likely be needed. If an infiltration type stormwater BMP is proposed, current regulations for infiltration systems require that the bottom of any infiltration device shall not be placed in locations with less than 2 feet between the bottom of the infiltration device and the SHWT [15A NCAC 02H .1008 (d) (3)], underlying impervious soil horizon, or bedrock (4 foot separation is recommended) and the minimum required infiltration rate is 0.52 inches per hour. Since the SHWT is 22 to 24 inches below the EGL, the bottom of the infiltration system would be required to be at ground level, which makes this type of stormwater BMP most likely unfeasible. 1111IT, IYl/-r111[•]lkN • Data only from hand auger borings, where performed, and conditions may vary in other areas of the basin.
