_Landmark Design headed a team of engineers and hydrologists in the development of a master plan to reclaim and redevelop the Bitter Creek drainage through downtown Rock Springs, Wyoming.  The Master Plan was completed in December 2007 and includes extensive analysis and documentation of conditions along the 3.5 mile long creek corridor, a variety of creek channel improvement options and alternatives, a design plan that removes 580 acres of historic downtown Rock Springs from the Flood Insurance Rate Map (FIRM) managed by the Federal Emergency Management Agency (FEMA), and various trails and related amenities that help return the creek into the physical and social fabric of the City.

In early 2008 funding from the Wyoming State Division of Environmental Quality - Abandoned Mine Lands Division was legislated as part of completing an Environmental Assessment (EA) for the project, signaling the first phase of improvements.  Landmark Design completed the EA in September 2009 and an Amendment in 2011.  A first phase of improvement included two detention basins on Dead Horse Canyon Creek and improvements to the Dead Horse Canyon Creek Levee, which resulted in over 200 acres being removed from the flood plain. Landmark Design continues to oversee the implementation of several related implementation projects which were spurred by the original Master Plan and EA.
