Without this structure, not <br />only will the Company be unable to deliver its water rights, but Loveland's intake structure will <br />also be inoperable. <br />Alternative 2 — Rebuilding Collaboratively with Improvements: The Big Dam already serves <br />multiple users. Additional collaboration or stream improvements were not identified. <br />Selected Alternative 3 — Reconstruct the Big Dam to Pre -Flood Conditions: The selected alternative <br />is to reconstruct the Big Dam to pre -flood conditions. This will be done in two phases. Phase One <br />will include rebuilding the crest of the dam to pre -flood elevations. Construction materials will <br />include matching quartzite blocks to retain the historic appearance of the structure, but will also <br />include reinforced concrete on the upstream wall face and crest cap. This will improve the integrity <br />of the dam beyond its pre -flood condition. This phase will also include the repair of the north <br />abutment buttress and the repair of erosion holes. Phase Two will repoint the masonry blocks on the <br />downstream dam face and repair various holes with shotcrete and grout. <br />The company has an agriculture exemption from the Corps of Engineers. The estimated engineering <br />and construction cost of this Alternative is $1,600,000 and is further broken down in Table 3: <br />
