This dissertation examines environmental policymaking as more of a symboldriven ideological contest over meaning than a rationally discursive democratic process through two interpretive modes of research: historical narrative analysis and text analytic frame mapping. Both are applied to the case example of the city of San Diego’s controversial policy innovation of indirect potable reuse via reservoir augmentation, or “toilet-to-tap,” as it became known through local news media. The dissertation develops its theoretical foundation from the literature pertaining to political communication in public policy, including the role of signs and symbols, media theory, frames and framing, and agenda setting. Electronic documents are used as data.
