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 majority of the lot slopes less than 15% southwestwardly. The proposed septic system will be located near the south property line. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Contours 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. 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, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties. Sincerely, Benjamin Schiller, PE Municipality of Anchorage On-site Water and Wastewater REVIEWED FOR CODE COMPLIANCE OSP211205, Rebecca Carroll, 07/06/21 NOTE: NO SLOPES >25% ARE WITHIN 50' OF THE PROPOSED SEPTIC SYSTEM. NO SURFACE WATER WITHIN 100' OF THE SEPTIC SYSTEM. ALL WELLS ON SURROUNDING LOTS WITH IMPACTS TO THIS PROPERTY ARE SHOWN. NO CONFLICTS WITH WELLS OR SEPTIC SYSTEMS.
