<br />- u.:: <br /> <br />slope stability problems of the area. Seeps are especially numerous <br /> <br />in the vicinity of the very large older slide mass (le). Before any <br />sizeable concentration of buildings or other heavy structures is con- <br /> <br />structed on these slopes, foundation investigations should include <br /> <br />evaluation of possible extensive slab slides which could develop on <br /> <br />surfaces of weakness parallel to the slope such as the contact between <br /> <br />mantle and shale bedrock. The usual analysis of the bearing capacity <br />of individual shallOw foundations would. not .prec1ude the possibility <br />of deeper failure initiated by loading from a.mu1tip1icity of indivi- <br />dual structures. <br /> <br />~,,:::.
