EFFICIENCY OF SEDIMENT BASINS: ANALYSIS OF THE SEDIMENT BASINS CONSTRUCTED AS PART OF THE STRAIGHT CREEK EROSION CONTROL PROJECT. FINAL REPORT

Erosion, sedimentation, and water pollution caused by runoff from the highway system are of concern to the Colorado Department of Transportation (CDOT). Compliance with federal and state water quality regulatory requirements along with a desire to minimize adverse environmental impacts have led to the need to control highway runoff. A variety of practices can be used to improve the quality of highway runoff and thereby reduce potential impacts to receiving waters. One such measure that can be constructed is a sediment basin. The Straight Creek Erosion Control Project, completed by CDOT in the summer of 1994, included the construction of eleven sediment basins between the "toe" of the I-70 fill slope and Straight Creek. These basins were constructed to reduce highway runoff sediment loadings into Straight Creek. This report provides information about the amount of material captured by the basins and their efficiency in removing sediment from the highway runoff. It is hoped that the report findings will help in future decisions on whether or not sediment basin construction is warranted and what sediment removal efficiency can be anticipated.
