Introduction: The purpose of this Stormwater Report is to document the stormwater management plan for the MacRidge &t Chicken Road Intersection Improvement Project. The project stormwater control measures are two bio-retention systems. The Appendix of this report contains the stormwater hydraulic calculation outputs from Pond Pack, a pre -development map, a post - development map, and a soils inspection report. 2. Project Location: The project site is located on Fort Bragg at the intersection of MacRidge and Chicken Roads (projects shown below in red on ESRI World Road Map). Mor��nf°n Ra 3. Existing Condition: OC O Cr n o a E S u c Telf: O� J a burg Dry sa + Q[ Nerwood 4r I � y 0 F�elcber Av e Bfldl o` �1 $3blebr a p", Oy61 E u a Cie Cliffbc Jennings Ln o[`we[` O o G See The existing property is mostly a road corridor with grassed shoulders and some woods. The NRCS soil maps show that the site is mostly Hydrologic Soil Group B and C soils (see Soils Map in Appendix). Soil Infiltration: The soils report performed by Hal Owen &t Associates Inc. is included with this report. Even though the native soils at the depths of the stormwater control measures will provide good infiltration (2 to 6 in/hr), all bio-retention systems have been designed with underdrain systems with upturned elbows. Per the NCDEQ Stormwater manual, if the infiltration rate is 2 in/hr or greater, then internal water storage (IWS) is not required, but IWS have been included in the bioretention systems.

Proposed Stormwater Treatment and Quality Control: The proposed bio-basin (SCM#1) provides water quality treatment. The water quality treatment volume is detained and will be drawndown slowly through the media and underdrain system. Water Quality Volume Provided in SCM (1.54-inch of runoff) = 5,145 cu. Ft. Water Quality Volume Required for contributing Drainage Area (1-inch) = 3,330 cu. Ft. The proposed bio-basin (SCM#2) provides water quality treatment. The water quality treatment volume is detained and will be drawndown slowly through the media and underdrain system. Water Quality Volume Provided in SCM (1.8-inch of runoff) = 1,330 cu. Ft.

The purpose of this investigation was to provide a general characterization of the soils in the area proposed for a stormwater infiltration device, including a determination of the depth to evidence of a seasonal high water table and estimation of the permeability of the various soil layers. In -situ hydraulic conductivity testing was not conducted. 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. Two stormwater control measures (SCM) are proposed at the site (Figure 1). A hand - powered auger boring was used to make soil observations at each SCM location. Detailed soil profile descriptions for each observation are attached to this report. A red ribbon flag was hung at each auger boring to facilitate survey location for the elevation. Soil morphological characteristics indicating a seasonal high water table (SHWT) were observed at 72 and 108 inches below surface at SCM I and SCM 2, respectively. Infiltration rates (permeability) of the soil materials are most limited to approximately 1.0 in/hr in the sandy loam layer starting at about 60 inches below surface at SCM 1 and about 108 inches below surface at SCM 2. I appreciate the opportunity to provide this service and trust that you will feel free to call on me again in the future.

A site investigation has been conducted for the above referenced property, located on the southeast of the intersection of Chicken Road and MacRidge Road in Fayetteville, Cumberland County, North Carolina. The purpose of this investigation was to provide a general characterization of the soils in the area proposed for a stormwater infiltration device, including a determination of the depth to evidence of a seasonal high water table and estimation of the permeability of the various soil layers. In -situ hydraulic conductivity testing was not conducted. 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. Hand -powered auger borings were used to make soil observations at SCM 3. A detailed soil profile description for each boring is attached to this report. A red ribbon flag was hung at the auger borings to facilitate survey location for the elevation. Soil morphological characteristics indicating a seasonal high water table (SHWT) were observed at 88 and 65 inches below surface at Boring 3A and 3B, respectively. The proposed area has significant slope and the depth to the seasonal high water table also transitions from deep to more shallow as you proceed down the slope. Infiltration rates (permeability) of the soil materials are most limited to approximately 2.0 in/hr in the sandy clay loam layer from 32 to 88 inches below surface at 3A and to approximately 1.5 in/hr in the sandy clay loam layer from about 54 to 65 inches below surface at 3B.
