Index-Galena Rd - MP 5.8 - Slide Repair

July 22, 2014 Update
The slide will be repaired during August 2014. Scarsella Brothers, Inc. will begin work on Monday, August 4, and finish near the end of the month.     

Description
Index-Galena Road is located along the Skykomish River in the Mount Baker – Snoqualmie National Forest in southeast Snohomish County. During a storm event in the spring of 2011 a landslide occurred at mile post 5.8 northeast of the Town of Index. The landslide is approximately 160 feet along the roadside shoulder.
During 2014 public works proposes to stabilize the roadway embankment by constructing a 160-foot long by 40-foot wide railroad buttress. A railroad ballast foundation will be installed with layers of geogrid to provide stability. Several finger drains (trench drains) will be constructed of railroad ballast (rock) at the base of the proposed buttress to help direct water away from the slide. The slope will be covered with mulch and topsoil, and seeded with a native planting mixture.
