![]() This three part calculation determines whether or not a berm of a designated height would fit in the space provided. Added to this is the area at the top of the berm or mound that is not part of either slope. You must calculate the horizontal distance up one side to reach the high point, then add the same distance to the other side to get back down to grade again. Height dictates the scale of the earthwork. The slope of a berm should be gentle if it is to support plants and avoid problems with erosion. Your designer knows this and will consider the following criteria for a successful grading plan. Berms too large cause many physical problems while those too small are clearly out of place. Rigid, non-sinuous shapes stand out like a sore thumb in the midst of a larger lawn or garden. One of the most common mistakes in landscaping is creating earthworks that look contrived. Maintenance equipment must be able to easily manage the turf as well. Because golf course berms are covered in turf, they must be graded to ensure turf grass will grow well upon its entire surface. These are the best examples to copy when creating a berm or mound for a new landscape's contours. A beautiful rolling course features bunkers along the edges of the fairways and low berms around each hole. Golf courses are designed by earthwork masters. Before you decide to integrate earthworks into your landscape, be sure you hire a landscape architect or civil engineer to create a detailed grading and drainage plan. Mounds tend to be low and wide to facilitate growing plants on top. A mound is more like an island rising from the ocean. Berms are often linear in nature, much like a river levee, though they may undulate and vary in height. The term earthworks is collectively used to describe mounded soil used for practical or aesthetic purposes in a landscape. In desert landscaping it's easy to see how the contractor graded mounds and earthworks to provide enhanced drainage and add interest to an otherwise flat sites.
