If the topography is not uniform across the length of the site the trenches will need to flare apart on one end to maintain contour. When this occurs it is necessary to use a center-to-center spacing that accounts for the flair or the installer will not be able to fit the system within the approved area. It is perfectly acceptable to have more area available,especially up and down the slope,than is required. 11160` Page of AOSE Form E Revised July 18,2007 ^ v Scale 1"= 100' . - Soil Profile Hole 6Z .),\\( House, Well and Drain Field Sites '''.\,....../ Lot A 50' Ri w A Division of Tax Map 114-36 D.9. 27451 P. 394 Albemarle County, Virginia Steve Gooch ConsultingGeologist gest N34°08'39"E qyS54°391r E n 703 Oliver Creek RoadFD 15 04 N Troy, Virginia 22974 22.42 D*07°47' 9" v Ls88O.09 1' Cs68.01 • z C8 s N 38°03158"E 1 „ pCQ < N41°57'01 "E • 34.33 • t1s 02°40' 7" 20.81' Lsle 64 311 `�4. to C8 s•N434.°2d4b"E �P o' PROPERTY LINE ALONG • • 0 CENTERLINE OF 30' N- g PRESCRIPTIVE ESMT. & o , odor^ PP 3 N44°00'57"E � l 4 4 �t53) 220.61 •'m*.. a 50.710 =4 ° ' m" ��/ PROPOSED DRAIN FIELD ' ' n=01 3a 3 R= 1500.90 V (PRIMARY AND RESERVE) b 1. 31 Lie 50.00, Q�► . .
