THE ECONOMIC ANALYSIS OF "SOFT" VERSUS "HARD" SOLUTIONS FOR SHORE PROTECTION: AN EXAMPLE

David R. Basco

Abstract


This paper presents the design and economic analysis for two alternatives (soft versus- hard) for shore protection of facilities at the US Navy's Fleet Combat Training Center, Dam Neck, Virginia, USA. Three key factors are discussed that resulted in the selection of the soft alternative (dune construction and beach nourishment) which also included a buried seawall/revetment structure beneath the dune to provide a unique solution for shore protection. Construction was completed in the fall of 1996 and the results of the first year's monitoring effort are presented. The advantages of the soft alternative are many (environmental, recreational, etc.) and may even include the economic advantage as demonstrated in this paper for one site on the Atlantic Ocean.
