WEl) has observed construction of the rockery wall built un the adjacent Lot 74 and has been informed that the gall on Lot 75 will be similar in construction and dimensions. The wall will be constructed on an east facing residual basalt slope of approximately 3:ttH:V)original grade. The wall is to be about 4-feet in height and approximately G0- feet in length, and constructed of angular basalt boulders slacked two 12) high with 8-inches of embedment and a 4:1 hatter- The area below the wall is flat and the slope above the wall will be steepened to 2:1 for a distance of ID-feet. The current exposed cut face of the slope is very stiff bard reddish brown, weathered basalt with about a 1-foot topsoil zone. No seepage was observed from the cut bank. The boulders shall have good contact points, drained. backfilled with crushed aggregate. and boulder sizes shall be at least 2 to 2.5-feet in diameter. Stability calculations for a wall of this type are attached,which show all required factors of safety are met. We recommend that surface water be directed away from the walls as best as possible and that drainage • at the base of the wall be periodically inspected and maintained. No surcharge loading from foundations shall be imposed on the wall,and the base boulders of the wall shall not be undermined by landscaping excavation, nor should water be allowed In pond at the base of the walls. Yard irrigation shall be directed away from the wall Sincerely. -- Branch EtylineeringInc-. �,:=•.: �'"-\ Ronald t. Iletrrk, P.F..,G.E.
