Pannone, Principal Registered Professional Engineer E-mail:steve@Danengak.com September 27, 2017 Subject: Eagle River Valley Ranchettes, Lot 29D Upgrade Septic System Permit Request Design Narrative This is a design narrative for a permit to install an upgrade septic system to be issued for this property. The proposed system will serve an existing three (3) bedroom house. The existing drain field is in failure and will be decommissioned. The system will utilize a replacement 1000g septic tank and conventional drain field. This lot and the surrounding lots are served by AWWU water. There are no wells within 200' of the proposed septic system. 1. Soils. One test hole was performed in the vicinity of this system by PES in September 2017, and groundwater was monitored for at least seven days. Ground water was not observed to a depth of 13' below the surface in the test hole monitor tube in September of 2017. Bedrock was not encountered in the test hole to 13'. Based on the results of the percolation tests and overall soils appearance; an application rate of 1.2 gallons/day/square was used for a conventional wastewater system in the area of the test hole. 2. Soil Absorption System Design. a. See Sheet 1 of the design package. 3. Surface Water: There is no surface water within 100 feet of the proposed septic tank and drain field. The proposed drain field upgrade will maintain at least 100 feet from all surface water and drainage ditches. 4. Topography: The existing topography on the lot generally slopes from south to north, with a slope of approximately 10% in the area of the drain field. There are no steep slopes within 50' of this system. The proposed drain field will maintain 50' separation all steep slopes. 5. Drawing Markings: The Drawings are marked "For MoA Review Only". When written notification that the review is complete and that there are no further comments is received from MoA On-Site Department, the note will be removed and "Issued for Construction" drawings will be issued. The proposed installation will not affect the future development of this or the surrounding lots. Mailing: P.O.
