berm
Raised roadside ledge
A berm is a narrow ledge or shelf, especially a raised strip of earth along a road, path, or waterway.
Berms serve as barriers or boundaries—separating a road from a ditch, protecting against flooding, or providing defensive cover.
In landscaping, a berm is an artificially constructed mound: They built a berm to block noise from the highway.
