Project Description

P&J was contracted by the Colorado Department of Transportation (CDOT) to support recovery efforts after record rainfall in August of 2013 caused extensive flood damage throughout the Frontline and Foothills areas of Colorado. The majority of the debris that required removal was compacted under state maintained highway bridges by powerful water currents in the streams below.

P&J’s Contribution

Special techniques were developed by P&J to loosen and remove the compacted debris without causing additional damage to the bridges. Debris removal operations at many of the impacted bridges was complicated due to the presence of moving and nearly frozen water in the stream channels, and the fact that the operations were conducted during the winter season. In addition to bridge clearing work, P&J also removed flood generated debris from stream channels and public ROWs.

Bridge clearing and debris removal operations were conducted throughout six counties in northeastern Colorado (Boulder, Jefferson, Larimer, Logan, Morgan, and Weld). Some of the nation’s top trout streams are located in these counties and therefore debris removal operations were designed and implemented to minimize environmental impacts on these sensitive waterways. At the conclusion of the project, P&J had collected and processed debris which included woody vegetation, rocks, and sediment. A majority of the rock and sediment debris was reduced after collection and provided to CDOT for reuse during future road and stream bank restoration projects.
