In this study, the Regional Transportation District's (RTD's) light rail operations were examined for pollutant production and runoff. Conclusions from the study: Water leaving ballasted tracks carries only a small fraction of the heavy metals that are introduced into tracks from the light rail operations. Heavy metal concentrations at the most heavily traveled light rail station showed that pollutant concentrations were far below the regulatory limits., "August 2012.", "Report No. CDOT-2012-7.

In this study, the Regional Transportation District's (RTD's) light rail tracks were modeled to determine the Rational Method runoff coefficient, C, values corresponding to ballasted tracks. The runoff coefficient for ballasted tracks is significantly larger than the previously tabulated values for railroad yards. The higher runoff coefficient reflects the design of ballasted tracks to drain rainfall as quickly as possible., "August 2012.", "Report No. CDOT-2012-8.

Wildlife fencing along highways can lower wildlife-vehicle collision rates by excluding animals from the road right-of-way. Still, animals can breach fencing and end up trapped within the fencing along the highway right-of-way, exposing wildlife and motorists to the risk of collision. Wildlife escape ramps are designed to allow animals safe passage out of the right-of-way. Few recommendations exist on effective design of escape ramps and monitoring data are limited., Jeremy L.

Rich in mining history, the Mountain Mineral Belt design segment rises from the foothills. Dotted with historic towns including Idaho Springs and Georgetown, the Mountain Mineral Belt offers scenic views, lush forests, rocky hillsides, waterways, and access to local and regional destinations and recreational opportunities. The Mountain Mineral Belt design segment contains five Areas of Special Attention (ASA) including Floyd Hill, Twin Tunnels; Idaho Springs; DLD and Empire Junction; and Georgetown and Silver Plume., Description based on online resource; title from PDF caption (viewed January 2018)
