WRCC, jnc. November 10, 2009 (UPDATED November 19, 2009) Page 3 of 5 TABLE 1 WATF.R RifHT� Agenda Item 26a Appropriation Decreed Decreed Water Reservoir Date Storage Use Source Cobb Lake July 15,1919 9,113 Irrigation Cache La Poudre Cobb Lake Dec. 31, 1938 16,574 Irrigation Cache La Poudre Cobb Lake Dec. 31, 1938 20,432 Irrigation Cache La Poudre Project Description Four alternatives to stabilize the inlet ditch were considered. Alternative No. 1- Existing condition stabilization: This alternative would stabilize the existing inlet ditch by cutting back the ditch side slopes and a fence would be added. The estimated cost of this alternative is $1,130,000. Selected Alternative No. 2— Reconstruction along existing alignment: This alternative would include demolishing and re-constructing the existing inlet and drop structures, removing the rubble in the inlet ditch, cutting back the side slopes to be less steep, filling in areas in the existing channel bottom, constructing a new cast-in-place concrete inlet chute and stilling basin, and the acquisition of land to widen the existing easement. The estimated cost of this alternative is $1,433,000. Alternative No. 3— Reconstruction along new alignment: This alternative is sirnilar to Alternative No. 2 except along a new alignment. It would require a new inlet structure off the ditch rather than reconstructing the existing structures. It would not require as much fill or removal of debris, but would require the acquisition of a new easement and/or the purchase of additional land. The estimated cost of this alternative is $1,695,000. Alternative No. 4— New conduit along new alignment: This alternative would consist of a new inlet structure and conduit along an alignment to the north of the existing alignment. This alternative would also require the acquisition of a new easement and/or land purchase. The estimated cost of this alternative is $4,540,000. Alternative No. 2, reconstruction along the existing alignment, was selected because it addresses the Company's safety concerns regarding the degradation of the ditch in a cost effective manner, with less maintenance than Alternative No. 1. Construction of the Project is expected to begin in early 2010 with completion by May 2010. Table 2 shows the estimated Project costs.
