Lone Cabin Ditch & Reservoir Company September 13, 2013 (UPDATED September 26, 2013) Page 3 of 7 Agenda Item 29c Project Description In the June 2012 report prepared by Buckhorn Geotechnical, five repair options were offered ranging from installation of different types of impermeable membranes to the removal and replacement of the poorly installed material. The selected option is the installation of a chimney drain - Excavation of the slumped area and placement of filter material to drain to a new toe drain. This option uses conventional excavation equipment, and is estimated to be the quickest option to construct however the filter material must be imported. Other options that were considered are: Impermeable Membrane, Slurry Wall Installation, Vertical Membrane Installation, and Remove & Replace top 30 feet of the dam with quality materials. These options were dismissed based on cost, long term reliability, and irrigation season impact. Table 1 shows the Engineer's Estimate of Probable Cost. TABLE 1.
