Burlington Recreation Path North Shore Stabilization
The high lake levels and wave action from the Spring 2011 flooding of Lake Champlain caused significant erosion of the earth embankment below the highly used recreation path located at the north end of Burlington. The project was necessary to stabilize the existing slope and protect not only the recreation path but also an existing 72" storm pipe and an 18" sanitary sewer pipe located under the path. There were a number of factors such as groundwater seepage, highly erodible soils, accessibility challenges, steep slopes, environmental restrictions, and, of course, cost that needed to be considered. The final design used a combination of a smaller aggregate stone filter layer for protection from groundwater seeps and large diameter stones for slope reinforcing and wave protection. During the design environmentally sensitive plants were protected and preserved as Krebs & Lansing coordinated and facilitated permitting efforts with the US Army Corps of Engineers and the State of Vermont Agency of Natural Resources.
