Berms are simply mounded hills of dirt constructed for many reasons such as blocking out unwanted or unsightly views, directing or redirecting foot traffic or drainage, creating subtle and natural-looking privacy, adding raised elements to the garden, or simply emphasizing a particular area or focal point.
In medieval military engineering, a berm (or berme) was a level space between a parapet or defensive wall and an adjacent steep-walled ditch or moat. [1] In Snowboard Cross, a berm is a wall of snow built up in a corner. In Mountain biking, a berm is a banked turn formed by soil, commonly dug from the track, being deposited on the outer rim of the turn. In modern military engineering, berm has come to mean the earthen or sod wall or parapet itself. The term especially refers to a low earthen wall adjacent to a ditch. The digging of the ditch (often by a bulldozer or military engineering vehicle) can provide the soil from which the berm is constructed.

Creating a Berm Creating a berm is not that difficult. Berms are often constructed using some type of fill, such as sand, plant debris, rubble or asphalt, and soil. Use the fill material for the bulk of the berm, if desired. Recycled objects can also be used in pace of fill as long as the material is capable of retaining stability without deteriorating. Berms are simply mounded hills of dirt constructed for many reasons such as blocking out unwanted or unsightly views, directing or redirecting foot traffic or drainage, creating subtle and natural-looking privacy, adding raised elements to the garden, or simply emphasizing a particular area or focal point. Berms contain dense sediment materials that decrease water velocity, control flow rates and absorb excess water in the event of a flood. Normally placed in communities or sites prone to flooding, berms act as a barrier further mitigating the impacts of flood water. The terms berm, dike, and levee are commonly used interchangeably to describe such structures that are used for flood mitigation. The main difference between the terms is how each is built to mitigate flooding. This type of more permanent berm is often used to contain floodwaters, provide a barrier between land belonging to different people, or to keep livestock confined. When well maintained, they can last for centuries and have a profound shaping impact on the landscape that they are constructed in. Berm is also the word used to describe the banked turns on dirt tracks for off-road vehicle racing such as Moto-Cross and BMX racing. berm. 1. a level strip of ground at the summit or sides, or along the base, of a slope. 2. a nearly flat back portion of a beach formed of material deposited by the waves. 3. the shoulder of a road. berm. n. 1. a. A narrow ledge or shelf, as along the top or bottom of a slope. b. Pennsylvania, Ohio, Indiana, & West Virginia T Berms -- small, elongated hills with a gradual slope -- add height so you can showcase plants on a raised platform. You can use a berm to create a privacy screen with small trees, to divide sections of your yard or simply to add dimension to your outdoor space. Lay out the design for the berm on the ground with garden hoses; the garden hoses flex easily so you can achieve curves and make design changes before fully committing to a design. After you are satisfied with the shape of the berm, you can transfer the outline to the turf with landscaping spray paint. Learn: Berms. There are a variety of different terms for raised structures that act as a barrier between two areas. The terms berm, dike, and levee are commonly used interchangeably to describe such structures that are used for flood mitigation. The main difference between the terms is how each is built to mitigate flooding. Both berm and levee refer to raised embankments that are either man-made or the result of excavated land A berm can be a man-made sediment barrier placed at the edge of a slope or a wall built adjacent to a ditch to guard against potential flooding. Berms are placed in flood-prone areas to protect against erosion, run off and high water. The terms berm, dike, and levee are commonly used interchangeably to describe such structures that are used for flood mitigation. The main difference between the terms is how each is built to mitigate flooding.
