Summary

This project was constructed in the summer of 2014. The Clear Creek Tributaries Sediment Control and Metal Removal Project was a partnership effort between CDOT and the Clear Creek Watershed Foundation. The primary goal of this Project was to significantly reduce the loading of particulate metals, including the TMDL target metals cadmium, copper and zinc, from reaching Clear Creek. It consisted of construction of two sediment basins designed to capture metal laden sediments and particulate phosphorous in order to prevent these contaminants from reaching Clear Creek. The detention basins were designed to facilitate efficient maintenance operations to allow the captured sediment to be removed entirely from the drainage area and properly contained, likely in CDPHE’s Church Placer Mine Waste Repository.
