Abstract/Contents:States that "erosion control landscaping has become a huge industry, and a lot of work has opened up for landscape contractors in that field." Suggests that control of erosion, storm water and sediment is becoming more important noting, that "part of the reason is that as populations increase, there are more impervious surfaces in and around cities, which increases runoff and complexity of controlling erosion and sediment. Another reason that governments are realizing that increased runoff contributes to a lot of problems related to erosion, including pollution and loss of groundwater recharge." Explains that the "initial factors to take into account are slope, soil, exisiting drainage and any new structures that will go on the site." Notes that "rainfall estimates are crucial." Discusses potential design techniques which aid in erosion control explaining that "the approach to a job is different if it is a remedial project rather than new construction. A remedial project brings with it immediate problems, some of which will be obvious from the start because of the evidence of previous erosion. New development may have...caused the problems, which brings an added responsibility to the design." Notes that a "strict requirement...is to protect the needs of downstream waterways, some of which can be far off site." Also notes that "pollution or degradation of streams and lakes is not allowed (the cleaner the water, the more strict the requirements for runoff), and wetlands downstream may not usually be used as part of the water retention system." Explains that "one of the factors that makes an...erosion control project so complex is the amount of regulatory pressure on designers and contractors." Suggests that "another subject that erosion control designers must be aware of...is the types of materials available for construction."
