A Geo-Tech, Doug Putnam <br /> will be down here Thursday(20th) at approx. loam to look at the problems we <br /> are having along the channel . Doug seemed to have some of the same concerns <br /> I have about the type of failures we are having with such a dry year. Hopefully <br /> he can give us some advice. The area's we will be looking at are; <br /> 1 . North side of the Amazon both east and west of Bailey Hill . The worst is on <br /> the west side. <br /> 2. South side of the channel just west of Richardson Bridge. This is a area <br /> that we repaired last summer with our traditional method and it kicked <br /> within 3 months. This is the first time(besides Fir Butte) this has <br /> happened to us. We have always had good success by benching the area <br /> and building back up with rip rap. <br /> If you want to look at Fir Butte while he is here we can probally do <br /> that. This time of year we will probally have to walk in to that area. <br /> What the Corp has told me in the past is that the Fir Butte slide is on <br /> blue clay. The only way we can get that one to hold would be to drive <br /> piling. Myron thinks we may be also looking at blue clay on the spot by <br /> the Richardson Bridge. DR <br />
