This'soil is well suited to hardwoods and pines. The dominant trees are loblolly pine, southern red oak; white oak, and hickory. The main understory includes dogwood, holly, sourwood, and sassafras. Aycock soil is well suited to most urban and recreational uses. • This soil is in capability subclass Ile and woodland suitability group 2o. BaB=Blaney loamy sand, 2 to 8 percent slopes. This well.drained soil is on side slopes and narrow ridges of uplands. It is mostly in the western and northern parts of Cumberland and Hoke Counties. Individual areas of this unit typically are in long, narrow bands above and parallel to; most streams in the sandhills. They range from 10 acres to over 100 acres in size. Typically, the surface layer is dark grayish brown loamy sand 4 inches thick. The subsurface•layer.is.light yellowish brown loamy sand 21 inches thick. The subsoil, 37 inches thick, is brownish yellow sandy clay. loam in the upper part and reddish yellow sandy clay'loam in the 'lower part. The underlying material to a depth of-80 inches is yellow.loamy coarse sand. Permeability is moderately slow, and available water capacity is low. Reaction is very strongly acid or strongly acid throughout the soil, except where the surface has been limed. The hazard of erosion is moderate where the soil is exposed. A perched water table frequently 'is - above the brittle subsoil for brief periods after heavy rains. Included with this soil in mapping are small areas of. more clayey Gilead soils, sandier Candor soils, and Vaucluse soils, which have a sandy surface layer less than 20 inches thick. These included soils make up less than 20 percent of this unit. Most areas of this soil are in woodland, and the rest are mainly in row crops or pasture. This soil is suited to growing cultivated crops, such as corn, soybeans, tobacco, and small grains. Winter cover crops, minimum tillage, and crop residue management help to conserve moisture. Conservation practices, such as no -till planting and windbreaks, and crop rotations that include close -growing crops also help to conserve soil and water. This soil is well suited to Coastal bermudagrass and bahiagrass. Erosion may be a hazard where runoff concentrates in cultivated fields. This soil is suited to loblolly and longleaf pines. The understory is sassafras and blackjack oak. The brittle subsoil retards but does not restrict growth of tree roots. This soil is suited to most urban and recreational uses. Recreational lakes frequently are made by damming streams flowing through areas of Blaney soils (fig. 2). Housing developments often surround these lakes. Moderately slow permeability in the subsoil may limit the performance of septic tank absorption fields. The sandy surface layer is a limitation for some recreational uses. This soil is in capability, subclass Ills and woodland sui{ability group 3s. ' BaD—Blaney loamy sand, 8 to 15 percent slopes. - This well drained soil is on side slopes of uplands.

The subsoil, 37 inches thick, is brownish yellow sandy clay loam in the upper part and reddish yellow sandy clay loam in the lower part.,The underlying material to a depth of 80 i.nches is yellow loamy coarse sand. . .Permeability is moderate, and available water capacity is low. Reaction is very strongly acid or strongly acid throughout the soil; except where the surface has been .limed. The hazard of erosion is severe if the soil is exposed: A perched water table is frequently. above the brittle subsoil for brief periods after heavy rains. Included with this soil in.mapping are a few areas of, soils that have sandy material at a depth of less than 60 inches. Also included are small areas of more clayey Gilead soils, sandier Candor soils, and Vaucluse soils, -which have a sandy,surface layer less than 20 inches thick. These included soils make up less than 20 percent of this unit. Most areas of this soil are in woodland, and a small acreage is in cultivated crops or pasture. Areas of this soil are being converted to urban uses in many parts of Cumberland and -Hoke Counties. This soil is poorly suited to growing cultivated crops. Steep slopes are susceptible to erosion. If used for row crops, contour cultivation, striperopping, conservation tillage, and crop residue management help to reduce erosion. Using this soil for perennial hay and occasional row crops is a good conservation alternative. This soil is suited to grasses and legumes. This soil is suited to loblolly and longleaf pines. The understory includes sassafras and blackjack oak. The brittle subsoil retards, but does not restrict, growth of tree roots. Care should be taken during tree planting and harvesting to reduce erosion in disturbed areas. This soil is suited to most urban and recreational uses. Recreational lakes frequently are made by damming streams that flow through areas of Blaney soils. Slope and moderately slow permeability in the subsoil may limit the performance of septic tank absorption fields. The sandy surface layer and slope limit some recreational uses. This soil is in capability subclass IVe and woodland suitability group 3s. ICN Soil Survey erosion is severe where the soil is exposed. A perched water table is 1.5 to 2.5 feet below the surface. Included with this soil in mapping are small areas of sandier Blaney and Fuquay soils; less clayey Vaucluse soils; and Dothan soils, which have a thicker, less brittle subsoil. This Gilead soil has numerous seepage areas on hillsides. The seeps usually are less than 1 acre in size and are identified by a special wet spot symbol on the soil maps. In some mapped areas, short, vertical slopes have been created by the mass movement of soil down the hill. These exposed walls usually consist of massive, gray clay. The included soils make up less than 20 percent of most mapped areas. Nearly all areas of this soil are in woodland, and a small acreage is used for pasture. This soil is poorly suited to growing cultivated crops. Susceptibility to erosion is the main limitation. Because of slope, erosion is very difficult to control if cultivated crops are grown on this soil. Growing grasses or legumes for hay or pasture is a good conservation alternative. If this soil is used for pasture, proper stocking rates, pasture rotation, and restricted use during wet periods help to keep the pasture and soil in good condition. Gilead soil is suited to loblolly and longleaf pines. There are no significant limitations to woodland use and management. Care must be taken during planting and harvesting to limit soil disturbance and reduce erosion. This soil is suited to most urban and recreational uses. Wetness, slope, and slow permeability in the clayey subsoil are limiting factors.

The Tumb.erry Section I DESIGN NARRATIVE Floyd Properties and Development Inc. is proposing the development and construction of a subdivision project that will consist of 144 single family lots. The project is located off of NC Hwy. 401 - Fayetteville Road in the McLauchlin Township of Hoke County. Figure 1 - USGS Existing Site Description The majority of the site has been cleared and has been or is currently being used for crop lands. The un-disturbed are thickly wooded areas of pine trees, hardwood species and under story growth, located primary toward the Western and Eastern property lines and at the entrance to the site. The right-of-way area along Fayetteville Road is regularly maintained grass. The topography in this area generally slopes from 1% to 10% grades. A ridge line runs North -South centrally located through the project site with run-off flowing to the East and West. The East runoff drains to a tributary of Black Branch and the West runoff drains to Beaver Creek. Black Branch is classified as "C" the stream Index number is 18-31-19-5- 1, Beaver Creek is classified as "C" the stream Index number is 18-31-19-5. Both are with -in the Cape Fear River basin. Wetlands have been identified in an area near Beaver Creek. The wetland will not be disturbed during the construction of Section 1. Map 16 of the Hoke County SCS Soil Survey indicates that the soil types very greatly in the area of the project, they consist of (BaB) Blaney Loamy Sand, (BaD)- Blaney Loamy Sand, (GoA) Goldsboro Loamy Sand, (NoB) Norfolk Loamy Sand and (WaB) Wagram Loamy Sand Proposed Improvements The development proposed of this property will consist of a 144-lot single family residential subdivision, paved access roads, and the necessary onsite utilities. The subdivision will be accessed at one location off of the existing paved Fayetteville Road, which is to the East of the property. The proposed construction is limited to 25.5 acres. The development's on site impervious area will consist of 222,385.74 sf of paved roadways, 63,220.25 sf of concrete curb and 650,091.11 sf of impervious area for the 144 lots, which is 5,414.52 sf per lot limit. The total on -site impervious area is 909,532.80 sf, 38.71 % of the 53.94 acre total drainage area. The proposed site work to include erosion control measures, streets, storm drainage, water line & sanitary sewer utilities, power, phone and cable type utilities. Existing sanitary sewer is availability in the area, and will be used to serve project. The subdivision has been designed with asphalt pavement streets with concrete curbs. All site drainage will be collected by a series of catch basins that will then direct runoff into storm drainage systems then to the proposed stormwater BMPs for treatment prior to it being released from the site. Initially, all clearing will be completed, erosion control measures and sediment basin installed. Then streets will be graded. Once the site grading activities are completed, then the storm drainage and water lines will be installed as well as the electrical system. Once that work is finished, then the streets will be prepared for paving, concrete curb and gutter, soil type base placed and the asphalt pavement put down. During this portion of the work, the lot areas will not be disturbed. The Sediment basin will be left in place until all contributing lot construction is completed and the associated drainage area is stabilized. Once the erosion control sediment basin is no longer needed and has been approved for removal, any accumulated sediment will be removed and the erosion control sediment basin will be reconstructed into the approved Stormwater wet detention pond which will be used as the permanent stormwater management feature. All of the proposed impervious areas are located within one of two ("1" or "2") drainage basins. The amount of impervious area and the use of the curb and gutter and storm pipe collection systems makes this a high density project, per 15A NCAC 2H.1005 (3a) of the Administrative Geolechnical Engineering Services Construction Material Testing Civil Quality Control March 15, 2011 Moorman, Kizer and Reitzel, Inc. P.O. Box 53774 Fayetteville, NC 28305 Re: Letter of Transmittal and Summary of Testing Soil Science Report for Erosion Control and Site Drainage Calculations Tumberry Subdivision, Section Fayetteville, North Carolina KAM Project No. 11-066 Dear David: As requested and authorized, KAM Engineering Services, P.C. is pleased to present the results of the field testing and observations for the proposed infiltration basins at the proposed Tumberry Subdivision, Section I. The intent of this testing was to observe the soil profile and the groundwater conditions that will affect the drainage rate of the proposed basins. At the time of our site work, the preliminary site design had been completed by MKR, Inc. Our testing was performed at locations provided by our client to be within the floor of the basin (not including the fore bay). Based upon the site plan provided, the wet basin is designed with a floor elevation of approximately 227.0 feet. The controlling parameters for the design and construction of infiltration basins is the depth to Seasonal High Water Table (SHWT), and the permeability of the soils that should be expected in the floor and berms of the basin. Any restrictive horizons within the soil profile could substantially affect the drainage capacity of the basin. Hal Owen & Associates, under contract to KAM Engineering, has assisted with the field work and reporting for this work as a Licensed Soil Scientist. Mr. Owen's report is included with this cover letter for reference. The report details the procedures used, and the results of the soil observations and seasonal high groundwater elevation. Based upon elevations on wooden stakes at the boring location, it appears that evidence of the seasonal high ground water elevation is at 230.4 feet in location 1, and 232.9 feet at location 2. Because the SHWT was encountered at depths below the preliminary plan depths, our infiltration testing was performed at a depth of 2 feet above the evidence of SHWT. Therefore, our infiltration testing for Profile I and Profile 2 was performed at 232.4 feet and 234.9 feet, respectively. Our infiltration testing was performed with a compact constant head permeameter. Based upon the results of our testing, the soils will drain at a rate of approximately 0.004 to 0.018 inches per hour.

The purpose of this investigation was to provide a general characterization of the soils in the area proposed for stormwater management, including a determination of the depth to evidence of a seasonal high water table. All soil characteristics were described in accordance with the USDA Field Book for Describing and Sampling Soils. This report represents my professional opinion as a Licensed Soil Scientist. Soil profile descriptions were collected at the site at two locations as directed by you. A map indicating the two observation points is attached for your reference. Point number three was not investigated. Hand powered soil auger borings were advanced in the areas proposed for stormwater management. The following narrative describes the findings at the site. A full description of each observation can be found attached to this report. Profile l: An auger boring was advanced to a depth of 88 inches below ground surface. Soil morphological characteristics indicating a seasonal high water table (SHWT) were observed at 82 inches below surface. The ground elevation at this point is given as 237.25 feet above MSL, meaning the SHWT is at elevation 230.42 feet. Profile 2: An auger boring was advanced to a depth of 90 inches below ground surface. Soil morphological characteristics indicating a seasonal high water table (SHWT) were observed at 68 inches below surface. The ground elevation at this point is given as 238.56 feet above MSL, meaning the SHWT is at elevation 232.89 feet.
