saturation which can lead to a slide. Efforts should be made <br /> by the prcperty owners to discharge roof runoff into existing <br /> storm drair.s systems or to the ditch at the base of the slope <br /> via a tightline drain system. Discharge of roof drairs into dry <br /> we11 syetema only leads to increased ground water seepage further <br /> down the slope. Swimming pools near the top of the slope can <br /> sdd substantial quantities oS water to the slope through leakage . <br /> Pool owners should pay particular attention to sealing cracks <br /> and looking for water useage which m�y indicate undetected ;eaks. I <br /> Pool rupture discharging large amounts of water over the slope I <br /> is particularly damaging. ,� <br /> �ue to an apparent change in soil types, property owners in the <br /> vicinity of 3400 Shore Avenue should pay particular attention to �� <br /> the above mitlgating measures. Within these areas where slide I <br /> activity is apparent and where vegetation should be redeveloped� <br /> we suggest placement of a chain link netting within the upper <br /> loose soil elevations. The obaerved use of chain link netting � <br /> within ather past failure areas has ahown and appears to be a � <br /> useful economic mitigating measure for stabilization o:' surface � <br /> failures. The chain link appears to provide resistance to i <br /> sloughing and is 21u1ctional in erosion control. We suggest the i <br /> chain link be placed down the slope scar areas to a point at least <br /> 2$' to 50' from the top-of-slope. A maximum staking distance <br /> of 20' intervals down the slope appears to be appropriate. <br /> Staking should use 1.$'-2.0" diameter pipe driven 2' to 4' into � <br /> the slope. Prior. to the placement of chain link upon the slope, <br /> fill and debrzs should be removed. After placement of the chain � <br /> link, the area should be revegetated with low growing grasses <br /> and shrubs, which can easily grow through the netting and help <br /> stabilize the surficial soils. <br /> � Municipal stormwater pipes discharge over the slope in several I <br /> places. These discharges are generally flowing on very competant <br /> soils and appear to be causing only minor erosion. The discharge <br /> pipes are frequently broken and are inoperative down the slope. <br /> Although erosion asoociated with these discharges appears minor, <br /> repair of these pipes would aid in reducing further erosion and <br /> associated slope instabilitiea. These pipes ahould be designed ' i <br /> and constructed to resist the forces associated with the expected <br /> -11- <br />
