Dear Plan Review Engineer: Please find enclosed our design documents for an on-site well and septic system serving the proposed 3 bedroom private residence at Rabbit Creek subdivision. We are proposing to install a private well, a 1,500 gallon septic tank with a lift station m~d a 25'long deep trench with 7.5' of gravel below the distribution pipe. On August 9, 2015, we excavated a test hole to determine ground water condition and soil absorption in the subsurface formation. (TH1). The attached soils log shows groundwater monitoring and percolation test results (4 minutes/1 inch). The topography of this lot is as follows: Steep slopes greater than 25% to the south as shown in our topographic map, and; About 5%-8% cross slopes to the east at the lower level. We are requesting a distance waiver between the proposed deep ~xench and the existing ground slope to the south, which is greater than 25%. The required 50' from the proposed trench cmmot be obtained due to the steep slopes and the location of the north property line. Based on the MOA guidelines regarding distance waivers, the maximum attainable distance to a slope steeper than 25% is only 32'. We therefore request a distance waiver for this on-site septic system. The on-site water and septic system will have no adverse effect on the surrounding wells, septic systems, or surface waters if the system is constructed as per the approved design documents. Drainage patterns will be restored to pre-construction conditions. If you have any questions, please contact me at 947-3499.
