Dutch Creek Drainage Improvements at Coal Mine Avenue, Littleton, CO 80123

Posted on December 17, 2020 at 7:51 AM by Lindsay Townsend

Project Background:
Link to see Dutch Creek at Coal Mine Avenue Location on MapThe crossing of Dutch Creek under Coal Mine Avenue is severely undersized for large storm events resulting in overtopping of Coal Mine Avenue. In addition, the existing culverts are near the end of their lifespan and need to be replaced. In partnership with Mile High Flood District (MHFD), Jefferson County worked with Icon Engineering to improve capacity and stabilize the channel of Dutch Creek.

Project Scope:
The project highlights consist of the following improvements:
  • A three cell 14-foot by 6-foot box culvert will be constructed to carry the flows of Dutch Creek
  • The channel of Dutch Creek will be realigned
  • Sculpted concrete drop structures and boulder walls will be installed upstream and downstream of the culvert
  • A portion of the Foothills Park and Recreation District concrete trail to the north of Coal Mine Avenue will be realigned
  • Landscaping will be installed along the new creek alignment

Project Update (as of December 16, 2020):
The general contractor, Edge Contracting Inc. (Edge), will begin setting up traffic control and preparing to start construction over the last few weeks of December. Utility relocations will continue through the end of December. 

Construction is anticipated to begin January 4. Coal Mine Avenue will be limited to one lane of traffic in each direction through the project site during construction. Traffic delays are anticipated, and an alternative route is advised.
