(e.g. 600 gpd = 5 bedrooms) <br /> Proposed house locations were not provided by the property owner or developer as required by <br /> 15A NCAC 18A .1900 - .1970 (The Laws and Rules for Sewage Treatment and Disposal <br /> Systems). <br /> The design flow, type system, and pump requirement are subject to change based upon the <br /> application and site plan or plat submitted for the Wastewater Construction Authorization. <br /> The blocked areas on the accompanying plat are the limits of the provisionally suitable soils as <br /> evaluated by the Orange County Health Department. <br /> It should be noted that all lots having a conventional-type drain field with pump are reviewed at a <br /> minimum of every five years by the health department as required by 15A NCAC 18A .1961 <br /> (Maintenance of Sewage Systems). <br /> Ultra Shallow Trench Conventional Systems are placed in areas with 24 inches or more of <br /> provisionally suitable soil/site characteristics and a 6-10" soil cap is placed over the trenches. <br /> Shallow Trench Conventional Systems are placed in areas with 30 inches or more of provisionally <br /> suitable soil/site characteristics. <br /> Conventional Trench Systems are placed in areas with 36" inches or more of provisionally <br /> suitable soil/site characteristics. <br /> Innovative Trench Systems can be used in areas with 24-36 "of provisionally suitable soil/site <br /> characteristics. <br /> The approved septic areas should be kept free of vehicular traffic, logging, grading, and <br /> compacting activities. It is the responsibility of the property owner or developer to maintain the <br /> integrity of the septic areas prior to system construction and installation. No parking, cutting or <br /> filling shall be allowed in or around the drain field areas. <br /> Drainage ways and easements should be utilized to convey storm water run-off to the storm <br /> water retention areas. These conveyances should not be located through designated septic drain <br /> field areas. <br /> This report is for planning purposes only and does not constitute any approval.
