~cz <br />Mr. Brent Anderson <br />Page Two <br />November 27, 1990 <br />to the toe of the slides, and the size and configuration of the ditch result in a <br />l potential for undercutting and/or saturation of the toe of the slide masses. In order <br />to address this potential problem, installation of rock drains similar to the one <br />proposed for Slide 3 (ACZ Inc., 10/1/90) is recommended. Given the configuration <br />and nature of Slides 1 and 4, a protective buttress over the rock drains is not <br />considered necessary. Upstream diversion of ditch flows to the outside of the <br />access road above the rock drains is also recommended to minimize drainage <br />requirements and insure continued stability. <br />Sincerely yours, <br />ACZ INC. <br />/~7 ~ <br />Jerry ~ettleton <br />JMN:rce <br />enclosure <br />
