What is a grade stabilization structure?
These structures include an embankment built across a natural or constructed watercourse to move runoff water from one stable grade to another, using materials such as metal pipe, wood or concrete. Grade stabilization structures eliminate gully erosion and erosion within a waterway, reducing the sediment load and improving downstream water quality. These structures can also provide floodwater storage and serve as a water source for wildlife. A common use for these structures are to control the outlet of a grassed waterway, helping to maintain the aesthetics and trafficability of the waterway.WQ
