There wars discussion in the meeting about moviae the proposed Bull Sccp SpIDway <br />futlhu to ithe east. Denver W ata and South Adams would like [he opportunity to rev~cw <br />nay associated impacts to our Hazeltine property with such a design change. <br />4. The Slate Engineer's cu[ren[ policy requires that all impounded water not capnued In <br />prionry tirust be released to the stream system within a maximum of 72 Lours after <br />impoundment. Deaver Water and Soudt Adams need trr consider the implicatioru of this <br />policy oa jour operations for all design alternatives, <br />i <br />As mentioned in fete meeting, Denver Water and South Adams are no[ far enough along in our <br />design Of [hc resQVOtr complex to know whechec the eversnlal plan would accotttm«late the <br />conveysnce of Firs[ Creek Flood Flows through the reservoirs. This option may be possible. It <br />would seem beneficial to all pardes to avoid constructing the 4800 efs channel this wimer rf a 20D <br />efs channel would ultimately be svHicient We world like to suggest a course of acdon where <br />only the smalls Q00 efs) charnel is cottsfrvcred 4~is wiener. Tlu daisioa whether to enlarge [hc <br />rJUnncl i0 acco[nmodaic 4800 efs would ba mach in a few years. We have summarizeri our <br />IeCOnnaeadaLOn ~s fO110W5: <br />1. Design and cotutrua the Bade control s[ructwes and improvemenu to the Bull Seep fa <br />Alternative 2 (200 efs) this winter. Coostruc[ ao spillway. <br />2. Complete.the lull, detailed design [or Alternative 1 [o take [hc 4800 efs through the BWI <br />Scep Slough, wrvch fOllOws the d.'sign pre mice of the existing reclamation plan. <br />;. Negotiate~the terms necessary with all afExted parties and regulatory agencies (Corps of <br />&tt;meers, Macintosh. Fulton Ditch Co. a td others) to ensure [lent AI[nnative 1 would be <br />a workable plan if it is iatplementcd. <br />4. L>etermine a currem cost estimate for [he agreed-upon Alternative 1 design <br />5. Wail for Denver Water and South Adam, to determine the best design for the reservotr <br />complex. if :outing Fast Creek through me reservoir complex is selected as the best <br />option, no additional work need be done oa the Bull Seep Slough channel. Dem-er Water <br />and South Adams would coordinate the design of a spillway system subject [o approval <br />from Urban Drainage and the DMG. COrISWC[IOn cos[ allocations for such wak would <br />be agreed upon by the Bull Seep Task Face. If Denver Wartt and South Adams' plan <br />will not accommodate such spillways in the raervotr complex, then the spillway for <br />Alternative 1 would be constnrc[ed and the Bull Serp Slough channel would be expanded <br />to carry 4800 efs. <br />We realize that this approach would require a¢reumeats on me sharing of shun-term and tong <br />term costs and ihst this agrsment may be di[fii;dt to achieve. In drat case these may be no <br />al[rmative then [o proceed with Alternative 1 at his time. Please feel free to give me a call at <br />303.628-6605 ro discuss any of these issues. <br />Sin/c~er~ely. , <br />Jessica Barbi¢, PE <br />Project Enginecf <br />cc: Jimlones,ISACWSD <br />John Htttnilton, Muller Eagincrnng <br />Don Kennedy <br />Mike W'alfc:r <br />E & C File <br />C'\W INDOWS\TEMP\8-29 meeting tloc <br />
