Today is a big day! As of July 26th, 2021 our partners at Ecological Resource Consultants and Tezak Heavy Equipment will be mobilizing crews and setting the stage for channel construction and Rock Island Road bridge installation. The pull off at the intersection of Tiger Road and Rock Island Road will be used by crews to stage equipment and will be closed to overflow parking from the Tiger Trailhead through the end of the construction season. Rock Island Road will remain open to the public throughout the construction phase, including during bridge installation.
This seasons work will include final grading, channel construction, bank stabilization, bridge installation, and initial revegetation of the site. When completed, 4,800' of new channel, 13 acres of riparian habitat, and 5 acres of upland habitat will be created on Reach B. The new channel will include 20 riffle-glide-pool sequences that mimic the natural morphology of reference streams in similar elevations and habitats. These sequences will provide natural aquatic habitat and will be paired with large woody debris and boulder installation to further diversify the available habitat along this stretch of stream. New bank stabilization techniques that utilize logs and root wads will also be installed on this stretch to serve as fish refuges. By taking into consideration lessons learned on Reach A, we have made these improvements to the Reach B design and will continue to utilize the most current restoration techniques.
Last week, Summit TV was on site to shoot some aerial photography prior to the beginning of construction (see the photos below). Colorado Parks and Wildlife also toured the Reach A site recently to see an example of successful stream restoration and the following establishment of brook trout and sculpin populations. We hope that this project can continue to serve as a model for stream restoration, both here in Colorado and around the country.
Keep following the blog to see progress photos throughout the construction season and the transformation of the site.
