About This Project
The Jordan Tributary Reach B & C Improvements Project is a collaborative effort led by the Mile High Flood District (MHFD) and the Town of Parker. Olsson serves as the design engineer, Naranjo Civil Constructors is the prime contractor, and Western States Reclamation will complete revegetation throughout the restored channel corridor. The project enhances stormwater function, addresses sedimentation issues, and restores important elements of the Jordan Tributary drainageway within the Bradbury Ranch area. This work includes channel excavation, reconstruction of forebay structures, sheet pile cutoff wall installation, trail removals and replacements, a new Type R storm inlet near Martingale Drive, and full vegetation restoration. Improvements will also include localized dewatering at each forebay and at the sheet pile and pedestrian bridge locations, utility coordination with the Xcel gas line, earthwork to address the upstream floodplain pinch point, and regrading and soil preparation throughout the site. In addition to improving drainage capacity and sediment capture, the project provides long-term ecological and community benefits. Restoration elements include wetland plug installation, upland seeding, soil amendments, mulch treatments, and erosion control to stabilize restored areas. Work will be conducted in phases over roughly four months, with Reach B completed first followed by Reach C. Through careful coordination among MHFD, Parker, Olsson, Naranjo, and Western States Reclamation, the project strengthens the overall resiliency of the Jordan Tributary system while enhancing public access, safety, and natural habitat.

Project Details
Localized dewatering required at each forebay, sheet pile, and bridge location, using a whisper generator or quiet-pack system
Approximately 70% of earthwork generated from the floodplain pinch point upstream of Martingale Drive, requiring significant hauling and potential dump-site coordination with Parker
Removal of trail sections and adding a new maintenance access path.
Construction of five new forebays, a few with vegetated bases, to help with stormwater discharge.
Major Work Items
Earthwork, excavation, topsoil stripping and replacement for both reaches
Installation of new forebays, concrete aprons, and the sheet pile cutoff wall with steel cap
Removal and replacement of existing RCP, FES, curb and gutter, maintenance access trail, and inlet structures
Revegetation including wetland plug installation, grass plugs, broadcast seeding, soil preparation, and mulch treatments
