A marine environmental issue around urbanized area has become a serious problem in recent years. Consequences of expansion of urban area reveal themselves remarkably at the coastal area not only due to an increase of reclaimed land from sea, but also an environmental burden from household effluent. And it should be noted that the sea is an end point of almost all environmental burden that is emitted from their source spread in land. Because of these points as background, the establishment of risk analysis model for marine environment is necessary to balance the urbanization and the environment protection at sea. In the beginning of risk analysis, the estimation of value and the efficiency of mitigation for marine environment are to be determined because the loss of value of environment can give rise to environmental damages as vicious spiral. In this paper, the CVM (contingent valuation method) is applied to the estimation of value of marine environment of Fukuoka bay area. The environmental problem of the construction of Island city by reclamation in Fukuoka bay is analyzed as a trial example for risk analysis model, and the methodological effectiveness by mitigation for marine environment is estimated by the multi-criteria analysis.
