The state is responsible for providing protection and management in accordance with the authority it has so that environmental damage does not occur that causes flooding and is able to anticipate the possibility of flooding again in the future. However, in practice it cannot be denied that state administrators, in this case the central government to local governments, have the possibility of committing a mistake as an act against the law because it does not provide fulfillment of the rights of citizens, so that the community can sue the state for that mistake. Citizen lawsuits do not lead to claims for losses, but demands in the form of issuing general policies by the government. The purpose of this study is to find out about the efforts of citizens to obtain protection from the threat of flooding through the citizen lawsuit mechanism and to find out how the potential citizen lawsuit mechanism in resolving floods so that it does not happen again. This study uses a normative juridical approach by using perspective analysis. The results showed that the problem of flooding resulted in citizens not getting their rights to a good and healthy environment. The citizen lawsuit is carried out so that state officials issue a general regulatory policy as a preventive one (disaster mitigation) so that floods do not occur again in the future.
