Bull Run Road, a two-lane residential road abutting a perennial stream, underwent a slope failure during a large storm event. Heavy stream flows scoured the toe of the roadway embankment causing the roadway slope to fail and restrict capacity to one lane. The Town of Roxbury secured FEMA funds to evaluate the situation and implement…
Along Otter Creek, a 160-ft-long, 20-ft-high slide occurred on the Gooseneck Bend Road embankment, disrupting the roadway’s stability. The Town of Weybridge secured FEMA funding and engaged D&K to evaluate the failure and design long-term improvements that armored the embankment along the roadway using stone armoring and plantings, stabilizing the immediately adjacent gravel road.
