drainage of seepage areas associated with the slide. As a minimum, we recommend the <br />drain consist of a 3 foot thick blanket of crushed rock over seeping areas. The blanket <br />should be connected to the main valley drain with crushed rock with a minimum area of <br />9 square feet. Comparatively small flows are expected and piping of spoil into the <br />crushed rock is not anticipated to be a concern. Also, the drain will be covered with very <br />coarse spoil from high lift end dumping. <br />If you have questions, please call. <br />Very truly yours, <br />Principal <br />MGG:RMM:mgg/am <br />(3 copies sent) <br />Ronald M.
