Installations of BMPs began in late October 2012 on Randell and Kew Vasseur roads in Fayston and continue this year on road sites in Warren, Waitsfield and Duxbury. Segments of ditch on Randell and Kew Vasseur roads were lined with stone to minimize erosion of these steep ditches. Preliminary assessments indicate the treatments are highly effective in reducing erosion. Following intense rain storms in late May 2013, the untreated site on Randell road showed evidence of considerable sediment accumulation in the silt fences we are using to monitor erosion. The paired site that had been lined with rock produced very little sediment.
