Blakley Drafting and Design Services, Inc. 6728 Carbonton Rd Sanford, NC 27330 Reference: Soil Scientist Investigation Glen Meadow Subdivision Phase 2, Angier NC Dear Mr. Blakley, A site investigation has been conducted for the above referenced property, located at the termination of Glen Meadow Drive in Harnett County, North Carolina. The purpose of this investigation was to provide a general characterization of the soils in the area proposed for a Stormwater BMP, 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. Hand -powered auger borings were advanced in the four areas proposed for the Stormwater BMP Swales (Figure 1) to a depth of 24 inches below ground surface. Soil morphological characteristics indicating a seasonal high water table (SHWT) were observed ranging from 12 to 18 inches below surface in the area of the four Swales. A typical soil profile description was collected and is attached to this report. I appreciate the opportunity to provide this service and trust that you will feel free to call on me again in the future. If you have any questions or need additional information, please contact me at vour convenience.
