<br />26. Scot[ Franklin recommended that the Company present two scenarios at the next <br />meeting. Both scenarios provide a design that reestablishes the channel grades in the <br />Bull Seep Slough to the pre-May 5th elevations. The first analyzes a 250-cfs channel <br />without a spillway. The second incorporates a 4,800-cfs channel downstream of [he <br />spillway, keeping the May 5th elevations as the control. <br />27. Chris Lidstone mentioned that the intent of the current design was [o establish a <br />phased system so one section can be constructed in accordance with the DM&G <br />order, while the remaining areas are discussed and designed. Bryan Kohlenberg <br />added [ha[ a stable solution still needed [o be designed to convey the 250-cfs through <br />the entire Slough reach not just the upper section as was presented earlier in the <br />meeting. <br />28. Jeff Schwarz went through a list of items to be developed and discussed a[ [he next <br />meeting: <br />i. Analyze the scenarios concerning the First Creek spillway and flows through <br />the Bull Seep Slough. It was suggested to establish two Bull Seep Slough <br />drop crest elevations (5023.0 and 5025.0) to compare. <br />ii. The company should show a proposed design conveying 250-cfs through the <br />Bull Seep Slough in a "non-erosive" manner to help the group decide on the <br />scale of structure [o be built. <br />29. Jim Weldon asked about responses to Denver Water's Memorandum of <br />Understanding (MOU). In general the group agreed [hat [he MOU was a good idea, <br />but should be addressed at a later date, possibly around mid-January. <br />30. Ken McIntosh added [ha[ [o help raise [he Bull Seep Slough elevations, he would <br />consider allowing overflows froth the spillway to leave the channel banks and sheet <br />flow across his property if i[ was done in anon-erosive manner. Bryan Kohlenberg <br />suggested the Company compare the erosion potential from sheet flow associated <br />with [he First Creek overflows and high flow events along [he South Platte River. <br />3l. Bryan Kohlenberg asked about the improvements to the Bull Seep channel around the <br />exposed gas line upstream of [he Bull Seep/Firs[ Creek confluence. Jason Murray <br />(Applegate Group) stated that the proposed grades for the Bull Seep would provide <br />cover over the gas lines. ]im Weldon suggested that an easement might be required at <br />the crossing, unless one is already in place. <br />32. The next meeting was scheduled for January 7, 2002, 1:00 PM, at UD&FCD <br />Minutes prepared by: <br />Craig D.
