The owner of Lot 8, Block 4, Mountainside Village Subdivision intends to place a new 4- bedroom home on the lot. We are therefore applying for a permit to construct a new well and sept c system on the lot to serve the proposed home. The attached Site Plan and backup documentation identify the location a.nd configuration of the new well and sept c system and the parameters used in the design. It also shows the location of the test holes and the alternate septic site. Existing drainage patterns are shown and w not be altered by the development of the lot. Two test holes were placed at the prop..o, sed location for the new and alternate absorption beds and revealed gravel w~th varying amounts of silt up to 25%. Groundwater was noted in the test holes during excavation at 8' and 9' and remained at those eve s durin~ the monitoring period. The soil percolated at a rate of 24 minutes per inch. We are~herefore proposing !o place 2 absorption beds each 50' long by 15' wide to treat the septic effluent. The p pe will be placed at 3 below the existing ground surface and the total depth of the beds will be 3.5'. Some coarse sand may be required to level the beds. A minimum of 3' of cover will be placed over the bed to prevent frost penetration and possible freezing. A Zabel flow splitter will be placed to insure even flow from the septic tank to the beds. The ground surface on the lot slopes as shown on the attached Site Plan with 2% to 5% grades from east to west near the northern portion of the lot. The slope becomes flatter proceeding west and slopes to, the stream flowing through the property at the west property line. The new beds w~ll be, constructed parallel t.o. the contours of the surface ~n conformance with Municipal requirements. Grading w~ll be accomplished to assure su. rface drainage is aw. ay from the new beds. The existing drainage pattern on the lot w~ll not be affected dunng development. If the system is constructed In accordance with our design the following statements apply: The system, if constructed as designed, will have no adverse impact on the wells Lot 8, Block 4, Mountainside Village Subdivision April 19, 2001 Page Two e in the area or those to be constructed in the future. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. The system, If constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, Michael E. Anderson, P.E.
