The Colorado Department of Transportation (CDOT) is performing construction and repair work in Boulder Canyon on State Highway 119 from Boulder to Nederland. The project is meant to repair damage done during the 2013 flood and provide an expansion of bike and hiking trails adjacent to the highway. The Boulder Waterkeeper expressed concerns about this project via a formal letter to CDOT that focused on impact to fish spawning and sediment loading into Boulder Creek. CDOT has failed to formally respond to these concerns. Boulder Waterkeeper has made several observations while driving in Boulder Canyon and noted poor installations of sediment control measures that are not in accordance to CDOT specifications. Pictures were provided to CDOT during a meeting and also sent to the CDOT Project Hotline for corrective action. Follow up observations are planned by throughout the year long project Boulder Waterkeeper to ensure stream protection.
