Septic System Design Dear On-Site Services Engineer: The owner of the above lot intends to build a 3-bedroom home on the property.We are submitting this permit application for the construction of a new well and septic system. The attached site plan identifies the location of the home and the proposed well, septic location and alternate site. No conflicts exist between this proposed system and any other well or septic system on this lot or adjacent lots. The ground surface on the lot slopes gently to the southwest at grades approximating 20%. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Drainage arrows are shown on the site plan indicating the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trenches will be constructed parallel to the slope as much as possible. Wells on this and adjacent lots are shown. The new system will be a minimum of 100' from all wells and surface water, and more than 5' away from the septic tank. Please refer to the attached test hole logs, soils lab analysis, plan and profile pages for the septic design. If this design is followed,there will be no adverse impacts to adjacent properties.

The assessment of the condition of the well and septic applies only to the conditions as of the day tested. The flow and absorption rates may change due to subsurface conditions that may not be observed from the surface, changes in land use, local soil characteristics, groundwater levels that may fluctuate during the year, quality of construction (workmanship & materials), the water usage of the family being served by the system and maintenance. The operational life of all well and septic systems are subject to d�`�1 these various and dynamic characteristics and are outside the control of the evaluator of the I'�•q well and septic system.
