It appears to me that it's 5 to 6 feet <br />3 in height in the highest point, and the--again, the photograph <br />4 doesn't do it justice--but the white material are the fines that <br />5 are moving down the hillside. <br />6 Slide 4 is erosion at the front entry gate. And I <br />7 believe the material that use to be in this eroded gully ended up <br />8 on the road in that storm event. It's very much similar to a <br />9 bridge scour, and this type of scour, in my professional opinion, <br />10 is not caused by drainage elements downstream. This type of <br />11 scour is caused by the volume of water that is moving through the <br />12 drainage channel. <br />13 This slide occurs approximately 1000 feet downstream of <br />14 the Castle Concrete entry gate. It's not on Castle property. I <br />15 believe it's on City of Colorado Springs property, and to my <br />16 knowledge this same eroded area occurred during that le.rge storm <br />17 event. <br />18 MR. O'CONNOR: Could you go back a second. I am <br />19 unclear why do you think that relates to Castle Concrete. <br />20 MR. NAGEL: I think it speaks to the volume of water <br />21 that is moving down their drainage way. It's the same drainage <br />22 basin. It's the same creek that--the water that comes •~f their <br />23 road goes through a culvert under the road and from that culvert, <br />24 it goes into this--into this open channel. <br />25 I also show Dan both of these areas when we were out <br />
