Berm

A berm is a raised strip of land or mound constructed to control water flow, provide a windbreak, or create a visual barrier in landscaping. Berms are often used to redirect runoff, prevent soil erosion, or add dimension and interest to a flat landscape. They can be planted with grass, shrubs, or other vegetation to blend into the natural surroundings and are an effective tool for managing water drainage in both residential and commercial landscapes.
