Recent Progress

WSDOT partnered with the City of Federal Way to develop a project that will create and restore wetland and stream areas along West Hylebos Creek to mitigate for impacts from the I-5 widening project.  This will be a separate project constructed before the I-5 widening.  Both WSDOT and Federal Way have hired a consultant, CH2M Hill, to design the project and develop plans for the mitigation site and to construct a new bridge on S. 373rd St. to accommodate a stream relocation and improve fish and wildlife passage. 

 

The wetland restoration project contract plans are complete and the project was advertised for bids on December 26, 2006.

 

A stream avulsion occurred during the winter of 2005, causing the west branch of Hylebos Creek to jump its bank and fork out into the pasture, flooding the key work areas for the future bridge and stream relocation work.  WSDOT obtained the permits and awarded a small contract to remove gravel from the stream and get it back into its former channel so that the work areas will be accessible and free of excess water during the 2007 construction season.  The job is currently in progress and is scheduled for completion September 2006.
