The Hood River City Council delayed going out for bid on Phase 3 of the Waterfront Stormwater Relocation Project after receiving a new cost estimate that increased by $900,000 from previous estimates.  Matt Huxley of project manager Tetra Tech said the jump from $1.6 million to $2.5 million was due to having a completed design and increases in unit prices.  Councilors were not pleased with the increase, but whether there is another option is questionable.  One possibility is changing from multiple filter locations to a single filter system on property between the railroad track and Interstate 84, which Huxley says might cost less but could be difficult to maintain long-term because of access issues.  City staff will come back with more information about the single filter system at the next Council meeting, and then a decision on how to proceed will be made.
