Several site visits <br />have been conducted to assess critical areas in the three corridors. Computer programming for <br />route assessments and hydrlmlic computations has been prepared specifically to address the long <br />distances and elevation changes along the alignments. Initial alternatives for river diversion <br />options and forebays have been identified and are being analyzed. Geologic assessments of <br />potential tunnel locations are being prepared. Water quality data has been assembled and water <br />treatment plant processes are currently being evaluated. <br /> <br />Task 8 - Evaluation of Project Configurations - A draft construction cost estimate for an entire <br />system with all physical components is being refined for one of the alignments and will now be <br />refined and utilized for the other corridors. <br /> <br />Task 9 - Documentation and Justification of Selected Configuration(s) - work is just beginning <br /> <br />Task 10 - Proj ect Development Strategies - work is underway using the "42 options" matrix as <br />the starting point. <br /> <br />Documentation <br /> <br />Task II -Study Documentation - a detailed outline for Final Report has been developed and is <br />currently being refined to address additional items. <br /> <br />ElOVLE <br />
