Despite the reality that advocates frequently expend significant resources to pass symbolic policies, this policy design has often been neglected by policy studies scholarship. We combine policy design and policy feedback theory to examine this oft overlooked policy design in practice using the case of California's human right to water law (Assembly Bill 685, or AB 685). Through semi-structured interviews, archival research, and document analysis, we reveal how grassroots advocates deliberately and effectively pursued AB 685 to build power across the water justice movement and catalyze narrative change about drinking water access, while also building state responsiveness on the topic. These interpretive policy feedback effects then accelerated the policy's resource effects through formal policy changes in funding allocations, administrative structures, and regulatory systems. Collectively, feedbacks from AB 685 have transformed the sociopolitics of drinking water access. Contrary to prevailing wisdom, the policy's ambiguity proved key to building the broad coalition necessary to accomplish these changes, and it facilitated work across policy venues and governance scales through time, which is critical to enacting transformational change. Based on these findings, we argue that symbolic policies merit attention as a potentially advantageous policy design for social movements seeking social change and transformation.
