39 <br /> INTRODUCTION & SITE DESCRIPTION <br /> A Reconnaissance Soil & Site Evaluation was performed on the 85.75-acre Meadowmont Farms <br /> tract located off Lawrence Road, Hillsborough, Orange County, NC (PIN:9883194355). Michael <br /> Wood, LSS was retained to evaluate the soil and site conditions and identify suitable areas for <br /> placement of on-site subsurface wastewater systems for a day school. The property was <br /> evaluated in accordance with the "Laws and Rules for Sewage Treatment and Disposal <br /> Systems", amended December 6, 2018. <br /> The area is a mix of open fields and woods. There are a few drainage ways that run through the <br /> tract marked in red as unsuitable topography on Figure 1. <br /> INVESITGATION METHODOLOGY <br /> The field survey was conducted on multiple dates in November 2021 by Michael G. Wood, LSS <br /> and Ethan T. Wood. Soil borings were advanced with hand-augers and soil color determined <br /> using a Munsell Soil Color Chart. Observations of the landscape as well as soil properties (depth, <br /> texture, structure, soil wetness, restrictive horizons, etc.) were recorded. Soil borings were <br /> described per the USDA-NRCS,Field Book for Describing and Sampling Soils, Version 3.0. Soil <br /> borings and site features are noted in Figure 1. <br /> FINDINGS <br /> Fifty-Four(54) soil borings were advanced, and their locations noted on Figure 1. <br /> Provisionally Suitable for Conventional Type Systems. Borings Provisionally Suitable for <br /> Conventional Systems include Gravel, Accepted,Alternative, Shallow-Placed systems. The <br /> surface horizon ranged from sandy loam to clay loam with friable, granular to subangular blocky <br /> structure. Subsoil was generally clay textured,with a firm subangular to angular blocky <br /> structure that extended from 26 to 40+ inches below the ground surface. This soil appeared <br /> adequate to support a long-term acceptance rate (LTAR) of 0.275-0.30 GPD/sq-ft. <br /> Provisionally Suitable for Low-profile Chamber Systems. Borings were rated as Provisionally <br /> Suitable for Low-Profile Chamber Systems had a sandy loam surface horizon with friable, <br /> granular to subangular blocky structure. Subsoil was silty clay textured, with a firm subangular <br /> to angular blocky structure that extended from 21 to 25 inches below the ground surface. This <br /> soil appeared LTAR of 0.225 to 0.275 GPD/sq-ft. <br /> Provisionally Suitable for Subsurface Drip Systems. Soil borings rated as Provisionally <br /> Suitable for Subsurface Drip Systems had a range of surface and subsurface textures with <br /> subangular to angular blocky structures that ranged in depth from 13 to 19 inches below the <br /> ground surface. This soil appeared adequate to support a LTAR of 0.10 to 0.125 GPD/sq-ft. <br /> Unsuitable. Borings were rated as Unsuitable due to a restrictive horizon occurring within 12 <br /> inches of the ground surface. <br /> Meadowmont Farms II Tract November 21, 2021 <br /> Job 8621 <br />
