Sinai Tract(Approx. 67 Acres) <br /> Mt. Sinai Road, Orange County <br /> PIN No. 9881-15-7138 <br /> Dear Mr. Akin: <br /> On April 11 —May l, 2012, Soil Services, PLLC (Soil Services) completed a detailed <br /> soil/site evaluation on the Mt. Sinai Tract. The evaluation identified areas of soil that have the <br /> potential for subsurface wastewater disposal. This evaluation was performed as part of the <br /> preliminary planning process. <br /> Soil Services traversed the site during dry conditions. Hand auger borings were used to <br /> evaluate soil conditions (texture, structure, depth, wetness condition, etc.)relative to subsurface <br /> wastewater disposal. Both man-made and natural landforms (drainways, slope, land <br /> disturbances,past and present uses, etc.)were observed as well. Based on these observations, a <br /> soil boundary between the potentially suitable and unsuitable soils were flagged and located with <br /> a GPS receiver. The criteria used to evaluate the soil and site is contained in 15A NCAC 18A <br /> .1900 "Laws and Rules for Sewage Treatment and Disposal Systems" and "Regulations <br /> Governing Sewage treatment and Disposal in Wake County, Amended 2.26.98" and/or Local <br /> Regulations. <br /> Results and Recommendations <br /> The property is located in the Carolina Slate Belt of Orange County, North Carolina. The <br /> uplands soils found on site are similar to the Tatum, Herndon, Georgville, and Enon soil series. <br /> The Georgeville, Herndon and Tatum soil series has a loam surface above a clay subsurface. In <br /> this soil,prohibitive characteristics are greater than 36 inches below the natural ground surface <br /> and are therefore generally considered useable for subsurface wastewater disposal. The Enon <br /> soil series has a loam surface above a clay subsurface. Due to the unsuitable clay mineralogy <br /> and/or shallow seasonal high wetness condition, these soils are generally considered unsuitable <br /> for conventional subsurface wastewater disposal systems. However, these soils may be suitable <br /> for alternative system types such as pretreatment drip or spray irrigation systems.
