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. The ground surface on the lot slopes toward the south, in some areas at greater the 46%. The proposed septic system is in an area where slopes are much milder, however, the it is within 100’ upgradient of those slopes greater than 46%. Please refer to the attached slope cross section for demonstration of the worst-case scenario of effluent travel given the existing grade of the property. We expect no daylighting of effluent. Elevations 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. Due to the groundwater depth in Test Hole #9A in conjunction with the depth of receiving soils found onsite in Test Hole #1, ERS may be necessary in order to utilize the receiving soil strata while meeting separation to groundwater. MOA Wastewater Code allows this for CAT III nitrate reducing systems. We would like to propose the use of ERS in this proposed design given the following justification: ERS Justification - The well log for Lot 10 to the east records a clay layer between 69’ and 320’ before drilling to a total depth of 472’. Additionally, a clay layer was encountered in Test Hole #1 at 18’ within 60’ of the proposed septic location. We expect this clay layer to be impervious or nearly impervious, and if effluent should ever reach this depth, it will simply run across the top of the clay strata horizontally and continue downhill rather than intermingle with local aquifers. The property to the south belongs to the State of Alaska Dept. of Natural Recourses and is a part of the Eagle River Greenbelt. There are no private properties downslope of this lot, and so there is no Municipality of Anchorage On-site Water and Wastewater REVIEWED FOR CODE COMPLIANCE OSP221008, Deb Wockenfuss, 02/14/22 potential of any adverse effects from this proposed design on any neighboring lots downslope. We therefore request a variance for the allowance of use of ERS in a conventional septic application. Lot 12 has shown varied consistencies of material throughout historical test holes in various locations on the property. Additional percolation tests will be performed on either side of the proposed septic location in order to confirm consistent soil conditions adequate for this design. Wells on this and adjacent lots are shown. The new system will be a minimum of 50’ from all wells and surface water, and more than 5’ away from the septic tank. The alternate site is located more than 6’ away from the primary. Please refer to the attached test hole logs, slope cross section, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
