<br />i <br />13. Area 1 Channel. The cross-section of the Area 1 slide in the <br />victnity o~~ie channel has been provided in the submit:tal. <br />The velocity estimate requested has not been provided, but the <br />critical information on particle size has been mentionE~d in the <br />discussion as ... relatively large, non-eroding rock~~." <br />Based on the size of rocks in the slide material avail~ible, <br />this qualitative description is acceptable. <br />A further discussion is provided which proposed construction of <br />an 8-foot wide channel with 3:1 side slopes and minimum 3 percent <br />channel slope. This channel sizing was defined by comF~arison to <br />the natural channel upstream and downstream of the inundation <br />area. A meander, formed by active channel processes, is expected <br />to develop in what is referred to as this "pilot" channel. Other <br />areas of the channel in the vicinity of the slides were verified <br />as not needing channel construction. The channel design proposed <br />is acceptable. <br />14-15. Silt Retention Facility Design. The commitment to provide the <br />engtneering~stgn bD~ays prior to anticipated construction is <br />acceptable. <br />JTD/eke <br />1931F/ <br />
