The SLOPE/W <br />computer printouts, located in Appendix B, document all inputs and stability analysis res~ilts. This <br />stability analysis result is based on the assumption that construction practice employed for this <br />embankment resulted in embankment material compaction of at least 95% Standard Proctor. <br />3.0 <br />Leidich, Tom (2000).
