$500,000 from 16 Water Users hoping to benefit from the storage reallocation. The 16 Water Users have entered into a contract arrangement with the CWCB using a mechanism known as a Letter of Commitment that specifies cost requirements and other obligations of the parties. Those Letters of Commitment have not been modified since they were first executed. Ie Cberry Creek Probable Maximum Flood (PMF) Study: Progress continues to be made by the Omaha District of the U.S. Army Corps of Engineers regarding the Cherry Creek Probably Maximum Precipitation (PMP) review and revised Probable Maximum Flood (PMF) study. The Corps has completed its detailed review of the site specific PMP study submitted by Applied Weather Associates on behalf of the CWCB. The Corps formally supplied a list of technical questions (31 questions to be exact) for which they request a response from A W A. This step will help to clarify and solidify the site~specific study findings that are scheduled to be used in the PMF analysis as a next step. In addition, the Corps is required by federal policy to undertake a reconnaissance level seismic study for the facility as a way of ascertaining qualitative risk from future earthquakes that may impact the dam. The Corps is seeking local seismic expertise to participate and review technical information for their seismic report. No work has formally begun on that effort, but Corps staff will notify CWCB staff regarding any progress or issues. For background information, the PMPIPMF studies were re-initiated based on direction received from Colorado Congressional delegates Tom Tancredo and Joel Hefley who, at the time, approved the Corps to move forward with the Cherry Creek PMF Study. The Corps will work closely with the CWCB and local interests during this important next phase of the work. This PMF study will be completed by Omaha Corps professional staff. The Corps and the CWCB have developed a work plan and are updating the project schedule for completing the major study tasks. The ultimate goal in this process is to complete the PMF study with the most reasonable PMP values, and then develop dam safety improvement recommendations at Cherry Creek Reservoir that are acceptable to local, state, and federal interests. The recommendations may lead to the need for physical improvements . to the dam/reservoir based on current federal standards and the desire for increasing public safety. Denver Water Cloud Seeding Evaluation: Based on the successful execution ofthe contract between Arizona, Nevada, California and the CWCB, Denver Water will likely contract with Western Weather Consultants for $40,000 worth of cloud seeding using six generators at Winter Park Ski Resort. This is the last year of their five-year cloud seeding permit. Denver Water wants an evaluation component and has worked with staff to develop a $90,000 Proposal. The CWCB would likely contract with WET-International consulting firm comprised of mostly retired USBR employees. The evaluation deploys an NCAR ice nucleus counter to measure concentrations of ice crystals during seeded and non-seeded storm events. Also, an icing rate sensor will be used to characterize timing and duration of wet and icy conditions thought to be good for cloud seeding effectiveness and compare them with contractor operational decision making. Soutb Platte Easements Update: The CWCB has received four requests in the last year for easement agreements with the CWCB: . Roxborough Park Metropolitan District needed two easements to use 11,000 feet, or just over two miles, of the CWCB right-of-way for a wastewater pipeline. . The second request was also by Roxborough and was used to reroute an existing stormwater drainage at Belleview to enable Roxborough to tie into a waste-water pipeline cleanly at Belleview Avenue. . The third request was by Columbine Valley Golf Club's request for 6.25 acres ofland to extend golf greens and tees and re-incorporate the South Platte River. . 30
