As previously indicated, the Yactors influencing slope stability <br /> can generally be classified as human inPluences. geologic/tectonic <br /> consideralions. drainage and vegetaticn. 1'esetaticn 3ocs r.ot <br /> directly influence slope stability but influences erosion which <br /> impacts slope stability. Most oP the areas of potential insta- <br /> bility observed appear to be related to human activity. The effecte <br /> of human activity are accentuated in the area of 3400 Shore Avenue <br /> by more sensitive €eologic and drainage co�dition`s� <br /> The area of greatest frequency of observed recent instabilities <br /> generally runs from abount 3421 Shore Avenue to 3727 Shore Avenue. <br /> This area is charactorized by shallow instabilities primarily <br /> related to dumping over the slope. From 3319 to 3409 Shore Avenue <br /> is an area of a bowl shaped slide. This area appears to be <br /> geologic more senstive to sliding due to a change in soi.l types. <br /> This sensitivity has been influenced_by slope dumping and possibly <br /> by redirected drainage through the area. Air photo evaluation <br /> indicates that surface water drainage £rom the low area south of <br /> � Shore Avenue was redirected into this area between 194� and 1967. <br /> Con�inued sliding and slope adjustment should be expected in this <br /> area. Some mitigating measures could be performed to substantially <br /> reduce or minimize Suture large scale slope failures and receding <br /> top-of-slope. <br /> Additional areas of future instability could develop in areas of <br /> debris dumping over the slope� vegetation removal� site regrading, <br /> storm water outfalls, swimmin� pools or constructio:i near the <br /> �op of the slope. <br /> MITIGRATIT�G MF9SlJRES <br /> The slope backwasting is a natural process which will continue <br /> with time. Slope features are generally shallow. The rate of <br /> backwasting will slow as the r�lope flattens. People with property <br /> in such an area will have to accent :he fact that sloughing of <br /> the steep slope will occur. . Fortions of 1awn. Pences, plantings, <br /> etc. near the top oY the alope will occasionally be lost to the <br /> backwasting process. Prevention of the backwasting is not gen- <br /> erally considered an economical trade-off for loss of lawn area. <br /> -9- <br />
