Pannone Engineering Services LLC Steven R. Pannone, Principal Registered Professional Engineer E-mail: steve@panengak.com 11 AUG 2015 Subject: RAVEN MOUNTAIN ESTATES #1 Bi L3 Septic System and Well Permit Request Design Narrative This is a design narrative for a permit to install an initial septic system and well to be issued for this property. The proposed systems will serve a proposed four (4) bedroom house. Currently the lot is undeveloped. The proposed system will utilize a 1250g septic tank with a bed absorption field. This lot is to be served by a private well. The surrounding developed lots are served by private wells; There are no wells within 100' of the proposed septic system 1. Soils. One test hole was performed in the vicinity of this system by Pannone Engineering Services in July of 2015, and groundwater was monitored for at least seven days. Ground water was not observed to a depth of 7.5' below the surface in the test hole monitor tube in July of 2015. Fractured bedrock was en~'ountered at the bottom of test hole. Based on the results of the percolation tests and overall soils appearance; an application rate of 0.8 gallons/day/square feet was used for a conventional system in the area of these test hole. A second test hole will be performed at time of construction in the area of the proposed drain field. 2. Soil Absorption System Design, a. See Sheet 1of 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 will maintain at least 100 feet from all surface water and drainage ditches. 4. Topography: The existing topography slopes up from the northeast to the southwest at approximately 21% in the area of the septic system. There is steep slopes within 50' of the proposed drain field (see Waivers). 5. Waivers: We are requesting a waiver for the separation distance from the absorption field to a steep slope to 28'. The slope is approximately 28' from the field. However, using a 25% infiltration line from the field the system will not daylight within 50' from the field (see Sheet 2 of the design package): 6. 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 no~e 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.
