� alternative would allow for a complete inspection of the shale formation once the old structure was removed. With the ' old structure removed, complete stabilization could be achieved with a new foundation. A concrete floor as described in alternative 2 would also be needed for the same reasons as described above. Using a bladder gate would the best and most modern method for diverting river flows. This alternative may cause some difficulties in diverting water � into the ditch because of the timing and size of the project. The cost of this alternative is approximately $350,000. The Selected Project The UPBCC plans to construct alternative #2. Features of this alternative are as follows: - Sheet piling and pipe piling will be used under all the � concrete structures for general stabilization and for protection from undercurrents. Pipe piling will be placed in an equally spaced pattern and the sheet piling will form the perimeter of these structures. - The energy dissipating floor will be monolithic steel reinforced concrete. This floor will be approximately 15 inches thick. - The new floor will be connected into the existing floor and foundation. At the same time concrete will be pumped under • the existing structure forming new support with the remaining shale formation. These features are shown in the preliminary set of plans found in Appendix A. Water Rights There are 100 shareholders in the UPBCC with rights to divert 234 cfs from the South Platte River consisting of a 20 cfs right � (1868/1869), a 50 cfs right (1882), and a 164 cfs right (1888). The official name on the decree is the UPPER PLATTE AND BEAVER CANAL COMPANY with their water being diverted down the UPPER PLATTE AND BEAVER CANAL.
