Spatial planning in coastal area is a comprehensive planning process. In addition to shape a system of spatial patterns and structures that increase the economic value of coastal area, planning document must be able to answer the environmental issues that occur in coastal areas. Semarang coastal area face a serious environmental problem. Beside the problems caused by climate change activities and sea level rise, the coastal area of Semarang is also facing a land subsidence disaster at a rate of 10-13 cm an even more. One of solution being developed by the government to deal with this problem is by the National Strategic Project of Seawall and Toll Road Integrated in the north coast. This paper aims to review the government awareness in address the land subsidence disaster on the spatial planning policy and assess the effectiveness of Seawall and Toll Road Integrated to face the land subsidence and its impact. With literature and policy review, we found that land subsidence has not been included as one of the types of disaster areas in the spatial planning documents. The natural geologist of Semarang that formed by young alluvium sedimentation, make the land still going a compaction due to natural activities or human activities impact, such as water extraction, or building loads.
