Coastal management begins with risk control, which is a collection of methods for evaluating the potential for harm and taking action to reduce or eliminate risk. Four methods of risk control are commonly employed: transferring, taking, avoiding, and reducing risk. These methods can be adjusted based on continuous monitoring. Risk assessment is the most commonly used method employed for the selection of risk-control measures. In this study, a risk-assessment-based information-provision method was proposed as a control measure for the risks that pose a threat to the safety of coastal users. The proposed risk-assessment method complements the current qualitative and subjective risk- assessment methods used by the Korea Coast Guard. A risk-assessment index and evaluation method were established to assess the risk grade of coastal activity areas managed by the Korean Coast Guard. This method was applied to 40 representative hazardous areas designated and managed by each regional office. By applying the established risk-assessment system, 11 sites were classified as grade 2, 25 as grade 3, 3 as grade 4, and 1 as grade 5. The risk grade of hazardous areas under the jurisdiction of the Korea Coast Guard Region-Central, which has a high rate of accidents and fatalities, was rated higher than that of other regional offices. The risk grade of each regional office, except for the central office, was rated between grades 2 and 3.
