In airports and airstrips where flammable petrol is kept, it must be contained with spill containment berms that prevent flows to the adjoining suburbs. These mounds must be inclined meticulously to merge with the rest of the landscape features such as trees, grass, flowers and steps. At five percent, the ground does indeed have a distinct gradient to it.
An inclined zone is one that has some portion of the ground surface located on a grade. However steep, all hilly areas possess a number of special circumstances that should be thought about in designing a mound for safety in industrial places or airports. A person must exert continual energy to stay put in any given location because there is a constant feeling of being pulled downhill.
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.
The likelihood of erosion increases as well on steeper land because exposed soil is easily washed downhill by a greater volume of surface water draining at a faster velocity. The design of undulating zones should be undertaken with care and understanding for the unique conditions that exist. The design guidelines that follow will help to accomplish this objective.
Then, the designer should attempt to match the proposed uses to slant conditions where they will fit with minimal grading. Above 25 per cent, it is too steep to safely mow. An outdoor entertaining space, on the other hand, could be placed at an angle that is between 5 and 15 percent by terracing it on different levels. Planted hills that do not exceed a 50 percent grade can serve as a transition between the elevations of the individual spaces.
On steeper site areas, outdoor uses may need to be molded by creating terraces that are cut at different elevations. This creates a series of large steps on which outdoor uses are placed. Retaining walls give them a more architectural appearance and allow spaces to be placed closer together. For example, a recreational lawn area should ideally be placed in a location that tilts between two and four percent.
They likewise can be designed as visual extensions by extending materials and edges into the adjacent landscape. Decks work well for spaces of limited size such as outdoor sitting, entertaining, and eating and many times can serve as architectural extensions of the house. The one disadvantage of steps is that they form barriers to universal accessibility. Everything possible should be done to take advantage of the inherent views, assuming they are worth capturing.
This is necessary but becomes more difficult on steeper sites because of the potential for erosion. Valley-like excavations into the earth, which are cut to catch and direct water, should be designed so they visually fit into the topography. Trenches that look like gashes because of overly steep side slopes should be avoided. The low side on the other hand, may be wetter because of the water that drains to it. Storm water must be directed in a manner that does not compromise the integrity of spill containment berms.
