Evaluating Small Dam Removal Planning in the San Francisco Bay Area
EVALUATING SMALL DAM REMOVAL PLANNING IN THE SAN FRANCISCO BAY AREA A thesis submitted to the faculty of San Francisco State University In partial fulfillment of the requirements for the Degree Master of Arts In Geography: Resource Management and Environmental Planning by Andrea Sarisky Sproul San Francisco, California August 2017 Copyright by Andrea Sarisky Sproul 2017 CERTIFICATION OF APPROVAL I certify that I have read Evaluating Small Dam Removal Planning in the San Francisco Bay Area by Andrea Sarisky Sproul, and that in my opinion this work meets the criteria for approving a thesis submitted in partial fulfillment of the requirement for the degree Master of Arts in Geography: Resource Management and Environmental Planning at San Francisco State University. Nancy Lee Wilkinson, Ph.D. Professor of Geography Jerry D. Davis, Ph.D. Professor of Geography EVALUATING SMALL DAM REMOVAL PLANNING IN THE SAN FRANCISCO BAY AREA Andrea Sarisky Sproul San Francisco, California 2017 Dam removal is now commonly being considered as a river restoration tactic as millions of small dams in the United States outlive their intended purposes and become liabilities or cause environmental degradation. This study evaluates two cases of small dam removal in the San Francisco Bay Area, gauging what aspects of the decision-making and planning process facilitated successful removal. Through the study of the setting, actors, steps of progression, and treatment of risks for each dam removal project, the cases are evaluated against one another via pattern matching and comparing factors of analysis. Planning at the watershed scale, the presence of protected salmonids, available funding, and strong leadership that incorporates multiple stakeholder viewpoints and embraces adaptive management were all found to be important factors leading to successful outcomes.
