The proposed system will serve a 5 -bedroom single-family residence. System: A 1500 gallon septic tank with a shallow trench absorption field. The absorption field will be 75 feet long and contain 4 feet of sewer rock. Soils: Two test holes were excavated on September 9, 2008. See the attached soil logs. Ground water was monitored for through September 12, 2008. Ground water was not observed. Surface Water: There are no surface waters within 100 feet of either the proposed septic system area or the reserve site. Topography: The property slopes steeply to the south. The proposed house and septic tank will be located along the north edge of the property. A sewer will extend from the septic tank several hundred feet to a level bench south of the house. The topography in the area of the drain field is generally level. The absorption field will be installed perpendicular to the slope. Waivers: No waivers are required. The installation of this septic system will not prevent wells and septic systems from being installed on the adjacent lots. The proposed septic system will not change the general slope of the area. Ponding and/or concentration of surface runoff will not result from this installation. If you have any questions or concerns, please contact me at 279-3916. Sincerely, Lars Spurkland, P.E.
