This book serves as a guide for local governments and private enterprises as they navigate the unchartered waters of investing in climate change adaptation and resilience. Local governments and private enterprises in the State of California have made tremendous strides in developing an adaptive capacity for addressing the current and future impacts of climate change. Both the public and private sectors have been united in their challenge to not only conceptualize the economic consequences of climate change but also to develop a practical set of methodologies and criteria for evaluating investments undertaken in the name of adaptation and resilience. Through successive adaptation plans and updates for nearly the past decade, the State of California has made advances in framing investment challenges and interventions in everything from transportation fi nance to disaster recovery grants and from life-cycle asset management to structured fi nance ( CNRA 2009 , 2016 , 2018a ). The 2018 update to the state adaptation plan has called for not only advancing innovation in fi nancing models but also the incorporation of climate adaptation into existing funding sources ( CNRA 2018a , p. 88).
