Quick Answer
Berms tend to be more visually appealing, as they can be designed to blend into the surrounding landscape, creating a natural and organic look. Their rounded or curved shapes can be aesthetically pleasing when done correctly. Berms can also be planted with vegetation to enhance their appearance.
Designing for Aesthetics: Berms vs Swales
Berms can be designed to fit the existing topography of the land, using the natural contours to create a visually appealing shape. A good rule of thumb is to keep the berm height between 2-4 feet, which allows for easy maintenance and visibility. When designing a berm, consider the surrounding landscape and try to create a seamless transition between the berm and the surrounding area.
Planting for Aesthetic Appeal
Planting vegetation on a berm can greatly enhance its appearance. Choose plants that are native to your area and can thrive in the local climate. Consider planting a mix of groundcover, shrubs, and trees to create a diverse and visually interesting landscape. Aim for a mix of plants with different textures, colors, and growth habits to create depth and interest. For example, a berm in a dry climate might include drought-tolerant succulents and shrubs, while a berm in a wet climate might include native aquatic plants and trees.
Contour Lines and Swales
While berms can be more visually appealing, swales have their own unique aesthetic qualities. Swales can be designed to follow the natural contour lines of the land, creating a series of gentle dips and valleys. This can be particularly effective in areas with rolling hills or undulating terrain. By following the contour lines, swales can create a sense of continuity and flow, drawing the eye through the landscape. However, swales can be more difficult to design and build than berms, requiring a greater understanding of hydrology and water management.
