Alternative #1 — Do nothing. This is not feasible because the existing rock-and-rubble core and <br /> deteriorated structures, if left in place as they are, will continue to cause Colorado to overpay <br /> the Rio Grande Compact and exacerbate dependence on groundwater withdrawals. <br /> Alternative #2 —Repair the existing structures. This is not feasible because the rock-and-rubble <br /> piles of debris offer no possibility of repair—they must be replaced. <br /> Alternative#3— Remove all remnants of the old core structure and replace with a new concrete <br /> core with manufactured gates and appropriate electronic and measurement instruments and <br /> repair and automate the existing headgate. This is the chosen alternative. <br /> ALTERNATIVE SELECTED--#3 <br /> OPINIION OF TOTAL PROJECT COST <br /> Alternative #1— Not considered further <br /> Alternative#2—Not considered further <br /> Alternative#3— Remove and replace all existing structures =$213,565 as follows: <br /> 14)) empfee,,,./PkWit- PeR217. <br /> Concrete core & diversion $ 75,000 <br /> 1 radial gate $ 20,000 <br /> Automation for 1 gate $ 25,000 <br /> Slide gate steel structure $ 5,000 <br /> 4 stilling wells @$1,000 $ 4,000 <br /> 4 Parshall flumes @ $7,000 $ 28,000 <br /> 4 sites, measurement &Telemetry $ 12,000 <br /> 1 Gateway node $ 7,000 <br /> Construction Subtotal $176,000 <br /> Feasibility Study $ 5,000 <br /> NRCS Engineering $ 15,000 <br /> Administration $ 12,000 <br /> District Telecom Match $ 4,565 <br /> Loan Origination Fee $ 1,000 <br /> TOTAL PRPOJECT COST $213,565 <br /> 13 Prepared by the Conejos Water Conservancy District, P.O.
