Embankment and Outlet Stabilization

A stable embankment is important to ensure that erosion does not contribute to water quality problems and that embankments are not breached - resulting in downstream flooding. Maintaining a healthy vegetative cover and preventing the growth of deep-rooted (woody) vegetation on embankment areas is an important component of stabilization. Animal burrows will also deteriorate the structural integrity of an embankment. Efforts should be made to control excessive animal burrowing, and existing burrows should be filled as soon as possible. Outlet structures are particularly prone to undercutting and erosion. Unchecked, a small problem can easily result in the need to replace the entire structure. A professional should be consulted if sink holes, cracking, wet areas around the outlet pipe, pipe displacement, or rusting of the pipe are observed.
