By taking into account all the physical, social, and economic aspects, this is the reason for the researchers' interest to conduct research related to the direction of Natural Disaster Mitigation Policy based on Environmental Physical Conditions and Socio-Economic Characteristics of Coastal Area Communities in Pariaman city. With Mixed Method methods, such as simultaneous and sequential data collection. Then descriptive physical environmental conditions and socio-economic characteristics, and Focus Group Discussion (FGD) in policy direction. The results of this study in the form of an explanation of the physical, social and economic Pariaman city, as well as the policies needed in disaster mitigation in Pariaman city
