The proposed system will serve a 4 -bedroom single-family residence. The lot is currently undeveloped. There are no septic systems within 100 feet of the proposed well location. Soils: Two test holes were excavated on May 3e, 2007 under my supervision. Generally speaking percable sands and silts were identified. See the attached soil logs. Ground water was monitored for through June 14, 2007 and was not encountered in either test hole. Surface Water: There is a spring at the toe of the slope, west of the proposed house location. A minimum of 100 feet separation between the nearest component of the septic system and this spring will be maintained. Topography: The proposed drain field is located on a slope of approximately 10 %. The drain field will be constructed perpendicular to the slope. Down slope of the proposed drain field the slope angle increases to a maximum of 24 %. Well: The proposed well location is greater than 100 feet from the nearest neighboring septic system. The installation of this septic system and well 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.
