25 <br /> Surface water was identified across the tract that will require a minimum of a 50-foot setback to <br /> septic system components. The location of these features is approximated onto Figure 1 <br /> Areas of Unsuitable Landscape were observed throughout the tract and include drainageways, <br /> concave landforms, ruts, hummocks,utilities, existing buildings, surface water and surface water <br /> setbacks, and other areas not suitable for the installation of septic drain lines. <br /> The soil units identified for proposed septic drainfields shall not be impacted by home sites, <br /> pools, garages, or other buildings and shall not be mechanically altered from the natural lay of <br /> the land. Septic system drainlines are installed along the natural ground contours and any <br /> disturbance to the contouring could change a site's functionality. As such, site disturbance shall <br /> be extremely limited to not render any areas unusable or require more expensive system types. <br /> System type, total drainline length and square footage requirements would be determined when <br /> the lot layout is finalized. Specific drainline length requirements, trench installation depth, <br /> drainline type and soil caps will all vary based upon the individual lot LTARs and usable soil <br /> depths. <br /> CONCLUSION <br /> The findings presented herein represent Earthly Elements' professional opinion based on our <br /> Reconnaissance Soil and Site evaluation and knowledge of the current laws and rules governing <br /> on-site wastewater systems in Orange County and North Carolina. Areas of Suitable soil was <br /> identified across the tract that can support initial and repair septic drainfields for single-family <br /> residences. Earthly Elements can provide septic system layouts, system designs and septic <br /> permitting assistance during the subdivision planning process, if desired. <br /> Soils naturally change across a landscape and contain many inclusions. As such, attempts to <br /> quantify them are not always precise and exact. Due to this inherent variability of soils and the <br /> subjectivity when determining limiting factors,there is no guarantee that a regulating authority <br /> will agree with the findings of this report. Any concurrence with the findings of this report will <br /> be made by Orange County at the time of Improvement Permit application. This report does not <br /> meet the requirements of SL 2023-90 a2-a6 or an Engineer Option Permit. <br /> 2 <br /> Hwy 86 N — Brown Tract <br /> Earthly Elements Job#: 24-032 March 19, 2024 <br />
