This accounts for only a portion of the trench, and the majority of the is more than 10’ from the lot line. The percolation rate of the underlying soil is under 5 minutes per inch. Effluent absorption is expected to be downward with little or no migration in a horizontal direction. The trench is located more than 100’ from all wells in the area and more than 20’ away from the existing septic on Lot 3 to the west. The placement of the system at its current location will have no adverse impact on the well or septic system on this or adjacent lots. We hereby request a waiver for the reduced separation of 9’ between trench and property line.

Development Services Department On-Site Water & Wastewater Program 4700 Elmore Road Anchorage, AK 99507 Subject: Eagle Crest #1, Tract B, Lot 2 – 19120 Citation Road Septic System Design Dear On-Site Services Engineer: The owner of the above lot intends to build a 4-bedroom home on the property. We are submitting this permit application for the construction of a new septic system. The lot is served by the public water system. The attached site plan identifies the location of the home and the proposed 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 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. Ground contours 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. A new test hole will be placed prior to construction to verify subsurface conditions. A change order will be sought if conditions are other than expected. We request a condition to the permit requiring the additional test hole. The water service on this lot is shown. The new absorption system will be a minimum of 10’ from all water services and 100’ from surface water and more than 5’ from the septic tank. The septic tank is more than 10’ from the foundation. Please refer to the attached test hole logs and plan and profile sheets for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
