The permit details the design of a new septic system on the property. During the development stages of building, the home orientation was adjusted. While performing the site layout, prior to the construction of the septic system, it was determined that due to field conditions the new absorption trenches would need to be shifted to the west. A waiver is required to allow for the trench to meet field conditions. - The new absorption trenches will be constructed 4' from the western property line. The neighboring property is vacant currently, this waiver will not impact the property negatively. The septic plan details a new well is to be installed on the property, if the waiver is granted the 100' separation can be maintained in addition to separation from foundation. We hereby request a lot line waiver be issued. Sincerely, Benjamin Schiller, P.E. October 6, 2021 MOA Development Services, On-Site Water & Wastewater Program 4700 Elmore Rd Anchorage, AK 99507 10/6/21 Subject: Overlook Estates #2 Lot 11 – NHN Eagle River Rd. Septic system design Dear On-Site Services Engineer: The owner of the above lot intends to build a 4-bedroom home on the property, so 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 as well as the proposed well, septic location and alternate site. No conflicts exist between this proposed system and any other well or septic system, whether on this lot or adjacent lots. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Elevation markers are shown on the site plan showing the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trench will be constructed parallel to the slope as much as possible. The septic system has been designed to accommodate sufficient separation from a stream located on the east side of the property 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. The alternate site is located more than 6’ away. Please refer to the attached test hole logs, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
