The existing bio-retention facility for which a stormwater permit is being sought is located within Phase I of the Joint Communication Facility. This site is located west of Reilly Road, south of Hurst Drive, north of Butner Road, and east of Malvesti Street within the new JSOC limits. In December 2010, Teng & Associates submitted permit documents and an application to NCDENR for the expansion of the existing building. NCDENR responded that they were unable to verify that the existing building (Phase 1) had been permitted. Fort Bragg's Water Management Branch (WMB) responded that Phase I had not been permitted due to timing (prior to NPDES Phase If implementation). On March 3, 2011 the Phase I1 construction project received approval of "Stormwater Permit No. SW6101204" to construct a "High Density Bio-Retention Project" from NCDENR. The following statement was made in this approval letter: "Note that this permit is for Phase 1I of this facility; and treats a portion of Phase I that is referred to in the permit as offsite area. The remaining portions of Phase I will be permitted separately or as a modification to this permit." On August 22, 2012, the Wilmington District of the Army Corps of Engineers contracted with Greenhorne & O'Mara to apply for a retrofit permit of the existing bio-retention facility constructed in conjunction with the Phase I construction. In accordance with the scope of work, a geotechnical engineer visited the existing bio-retention facility in order to obtain infiltration rates and assist with identifying the in -place soil profile. Considering exact depths and thicknesses of the different media were difficult to maintain, a copy of the original construction details have been included with this submittal. Also in accordance with the scope of work, a topographic survey of the existing site was completed in order to assist in determining the actual drainage area to the bioretention facility as well as documenting the characteristics of the constructed facility. In addition to the original construction details, the following information is being provided: Geotechnical Findings (2 included — September 24, 2012 and October 17, 2012), Drainage Area Map, Simple Method Calculations comparing required storage to available storage, photographs of the existing facility, USGS map identifying the project location, Stormwater Management Permit Application Form, Bioretention O&M agreement, Bioretention Supplemental Form, and $505 review fee. 114 -- Considering that the purpose of this application is to permit an existing facility, some information requested in the supplemental form has been left blank (i.e. pre/post 1-yr, 24 hour runoff and peak control, factor of safety for sizing underdrains, etc.) PLANNING • SITE ENGINEERING • TRANSPORTATION GREENHORNE & OWARA, INC.

This site is located on the Joint Security Operations Complex (JSOC) near the intersection of Reilly and Butner Roads on Fort Bragg Military Installation, North Carolina. Scope of Service The intent of our testing and field work was to observe and document the soil profile and the groundwater conditions that affect and influence the drainage rate of the storm water basin at this site. At the time of our site work, the basin had been constructed, and appears to be functioning properly. The details of the basin were provided in a series of drawings including drawing VF-101 (Existing Conditions Plan), drawing CG-104A (Erosion Control Plan), and drawing C-504 (Details) provided by Greenhorne & O'Mara. We have included a copy of each of these plans for your reference. Our testing was performed at one location, as shown on the attached plan. The controlling parameters for the infiltration basins is the depth to evidence of Seasonal High Water Table (SHWT), and the saturated (stabilized) permeability of the soils in the floor and berms of the basin. Any restrictive horizons within the soil profile could substantially affect the drainage capacity of the basin. Mr. Mike Eaker, a North Carolina Licensed Soil Scientist with Southeastern Soil & Environmental Associates, Inc., under contract to Building & Earth Sciences, has assisted with the field work and reporting for this work. Mr. Eaker's report details the procedure used in his field evaluation, the results of the soil observations, the depth to seasonal high groundwater and the depth to observed water at each test location. Mr. Eaker's report is included with this report. The storm water basin for this project has been designed as a bio-basin that functions as an infiltration basin. There is also an outflow structure that allows water to exit the system through a 610 Spring Branch Road Dunn, North Carolina 28334 Phone (910) 292-2085 Fax (910) 292-2192 GgocechAlcal. Environmental, and MacerhIs Engineers PVC underdrain. If the pond functioned as a true infiltration basin (with no outlet control structure), the floor of the basin will need to be set at an elevation that is 24 inches above the SHWT, and the soils will need to have an available saturated drainage rate of at least 0.52 inches per hour. In order to confirm this, the saturated permeability of the basin was calculated using a Compact Constant Head Permeameter (CCHP). The results of our testing are summarized below. Location I-1 Ground Elevation ft 258.6 Bottom of Basin ft 258.6 Depth to SHWT in 69 SHWT Elevation ft 252.9 Depth to Water in NE Water Elevation ft < 249.6 CCHP Test Depth in 45 CCHP Test El. ft 254.9 Ksat (in/hour) >5.0 • NE Not Encountered Summary of Observations and Recommendations Therefore based upon our testing and observations, the floor of the basin is at least 24 inches above the seasonal; high water table (SHWT), and the soils below the basin drain at a rate that is greater than 0.52 inches per hour. Additionally, the bio-basin filtration soil mixture is at least 36 inches thick at the location tested. The bio-basin soil mixture was tested to determine the particle size distribution.

I sw-sM JCU Bio-Basin As -Built 2 RD12389 Fort Bragg, North Carolina Geonchnlao. Environmental, and Matpriilt Enginagrt Statement of Design Method. Test Method and Limitations The flow of the near surface soils has been approximated using the concepts presented in Bernoulli's Equation for steady state flow and Darcy's Law for fluid flow through a porous media. Additionally, our Ksat values were calculated using the Glover solution which is dependant on the geometry of the bore hole, and the hydraulic head. To develop our recommendations, Building & Earth has measured/calculated the saturated flow rate (Ksat) for the soils at the site using accepted test methods and equipment. Ultimately, the drainage of the basins will be a function of the saturated flow rate of the soils, the surface area of the basin geometry, and the pressure differential (hydraulic head) induced by the storm water levels in the pond. In order to determine the appropriate Ksat for the soils in each basin, a small diameter bore hole was advanced to a pre -determined depth of interest. At this depth, a constant head (pressure) was established and maintained. Once our measurements approached a stabilized flow rate, our test was terminated. The recommendations in this report are limited by a number of geologic considerations. The primary limitation is the fact that geologic formations are variable in nature. The soils in Cumberland County are subject to perched water conditions, artesian conditions, and layers of undulating low permeability clay seams and layers. All of these geologic conditions have an affect on the steady state flow of groundwater. To the extent possible we have identified the material types that will impact the flow of groundwater, and have provided our professional opinion regarding the depth (elevation) to evidence of SHWT. Although Bldg & Earth has not provided an exhaustive survey of all of the soil deposits at the site, it is our opinion that we have properly and adequately characterized the site with regard to flow from the storm water basins that are planned for this development. Based upon our observations and results of our testing, it is our opinion that the existing basin has been constructed as designed, and is functioning as designed.

JSOC parking lot (near building 1840), Fort Bragg, North Carolina Dear Mr. Miller, An evaluation of -soil properties on a portion of the aforementioned property has been conducted at your request. The purpose of the investigation was to determine soil water table depths for use in stormwater retention design. Soils at the test site are most similar to the Wagram soil series (see attached boring; log). One boring; was advanced to a depth 9.0 feet. Seasonal High Water Table (SHW'F) as determined by evidence of colors of chroma 2 or less was encountered at a depth of 69 inches below the ground surface. The attached map shows the approximate location of the sample point (adjacent to the existing treatment area). I trust this is the information you require at this time.

On this date further analysis of the installed basin location was performed to determine permeability of the fill media within the basin; also a representative sample of soils used for onsitc fill media was obtained for laboratory analysis. The sample(s) were transported to our laboratory and tested in accordance with ASTM D 422 with ASTM D 1140, (Particle Size Analysis of Soils with Amount of Materials in Soils Finer than the No. 200 Sieve), ASTM D 4318, (Liquid Limit, Plastic Limit, and Plasticity Index of Soils), and ASTM D 2487, (Classification of Soils for Engineering Purposes) as well as analysis of chemical and organic properties. In addition to soil testing, soil borings were performed within the basin area to determine the profile of fill materials. Within the basin bottom, the boring showed an area showed surface vegetation (grass) with minimal homogenous organic content in the top two inches, Orange silty medium sand from two inches to twenty-four inches below subgradc, and stone layers of indeterminate thickness from twenty-four inches to at least thirty inches below subgradc. Due to the limitations of hand auger borings, exact stone thicknesses could not be determined, nor could the entire stone layer be penetrated; however, it did appear as though the stone was layered with pea gravel on top, followed by a layer of #57 stone, with additional pea gravel beneath. The perimeter of the basin was lined with small to medium vegetation including varied grasses and shrubs. The perimeter was also lined with landscape fabric topped by one to two inches of wood mulch. Below the landscape fabric was approximately six inches of brown mildly organic silty sand, with natural orange silty medium sand below that depth. We have included a copy of our data reports for the fill media sample and infiltration testing with this letter.
