Landscape architects are responsible for the design and implementation of safe spill containment berms in airstrips and petrol stations. In areas where jet fuel is stored, it is necessary to make precautions regarding the possibility of pipe bursts or overflow. To prevent this from flowing to the residential areas or adjacent buildings, the landscape contractor must develop a high mound.
Commonly, the ground has to be steeper than 3 percent to be perceived as being slanted. The steeper the site, the more pronounced these conditions are. All angled ground has an unsteady feeling to it for several reasons. First, it is difficult to get stable footing on undulating ground. While standing here, one foot is invariably higher than the other.
In either situation, extra time and money must often be spent to overcome the inherent instability of such a place. Its instability should also be beautiful to the eye. When compared with a level or horizontal plane, this visually implies potential movement, action, or change. It is obvious that any mobile object that is placed on this mound will likely move downhill.
Water, soil, stones, debris, and so forth all gravitate downwards over time. If possible, restrict movement in these areas to avoid the event of a catastrophe. Even people usually find it easier to walk downwards than uphill. It is necessary to grade the uphill area to divert the surface drainage around the house. Outdoor use areas can also be properly tailored by orienting them to minimize grading.
This is frequently accomplished by placing the long dimension of outdoor spaces parallel to the contours. Retaining walls, sometimes located on both the uphill and downhill sides of spaces, can also be employed as a means of accommodating the different elevation between spaces.
This approach gives a soft appearance to the landscape and separates spaces by the horizontal distance across the zones. Retaining walls should not exceed 3 or 4 feet in height without requiring special engineering and cost. To locate outdoor use areas in excess of 15 percent most often requires a deck.
In other words, the elevation difference between the top and bottom of the walk should be spread out over a greater distance in order to reduce the walk gradient. In extreme situations, walks or paths may need to switch back to avoid being too steep. During this analysis, the designer should determine what locations have the best views, both toward other areas and to the landscape beyond.
Steps are also a common necessity to provide access between nearby spaces. In addition, they should visually fit into context in terms of form and materials. Wide steps allow adjoining spaces to visually flow together. This location is usually not good for many outdoor uses and may be best set aside as a planted area or place where native vegetation is allowed to grow. Finally, all inclinations that are over 50 percent also should be left untouched to minimize erosion. Garden contractors usually design and build effective spill containment berms.
