CE 12592 �'J'%F •. 11/3/21..•'�G�i We were recently issued a permit for the installation of a new 6 -bedroom septic. system on the subject lot. After prepping the proposed septic area for installation, bedrock was found at a shallower depth than expected, forcing us to relocate the absorption bed. An effort was made to locate the existing cribs and trenches but nothing could be found that matches the Muni records. However, an undocumented, shallow, 30' long absorption trench was located and removed from the new proposed bed location. An old, cast-iron drain pipe was found near the end of the undocumented trench that ran towards the southeast property corner where a utility/power pole is located, but the pipe ended abruptly before reaching the property line. We expect that the existing documented cribs and trenches may have been installed over the property line and removed possibly when the utility pole was installed. We are therefore proposing relocating the bed in the location mentioned above. A minimum of 2' of receiving soils was confirmed over the length of the new bed location. The attached site plan identifies the location of the home as well as the existing 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 is mostly flat with a gradual slope less than 5% toward the northwest. 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 bed 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 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. Please refer to the attached test hole log, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
