Global sea-level rise (SLR) is among the most alarming aspects of anthropogenic climate change. The human impacts of SLR are experienced unequally between and within municipalities. Existing research has identified social variables that predict municipal adoption of adaptive SLR policy, but this work does not account for the locally specific social factors that shape particular policies to fit particular cases. This study describes social conceptions of the ocean and SLR policy for two coastal cities in western Washington: Aberdeen and Bainbridge Island. Examining conceptions of marine spaces provides insight into the complex process by which local physical and socio-demographic characteristics shape local policy. The study uses a grounded theoretical approach to content analyses, resulting in localized typologies of marine spaces as well as SLR policy profiles for each case. Results indicate that municipalities vary by both social conception of the ocean and SLR policy form. These findings elaborate upon the relationship between socioeconomic conditions and municipal climate change policy adoption, suggesting that in local media and policy discourse, the absence of relevant resources is related to adversarial conceptions of local marine spaces, while abundance of relevant resources is associated with a conception of marine spaces as natural resources.
