Dry Creek Rancheria Retaining Walls

Located in the rolling hills of Sonoma County, Dry Creek Rancheria and the River Rock Casino required the expansion of their main access road into their growing casino.  Originally part of the conceptual design team for this design/build project, Cornerstone was retained to complete the structural design of several soil nail walls on the site.  The steep terrain required the use of soil nail walls with retained heights of 40 to 45 feet.
