Abstract: Small, artificially-created islands may provide significant recreation and habitat benefits. Costs, however, can also be high. The initial dollar cost of creating an artificial island, and the subsequent cost in declining benefits as beach and habitat area are lost by sediment redistributions, can be reduced prior to construction. This paper illustrates how, by proper attention to eleven planning and design details, the benefit/cost of artificial islands can be optimized at a 1200 ha inland water body in central California.
