Event Title

Characterizing and comparing community exposure to coastal flood hazards in California: an integrated approach to support Salish Sea planning

Presentation Abstract

Coastal communities and habitats are continually vulnerable to flooding, and future threats are likely to increase due to the influence of sea level rise. Amidst the uncertainty of these threats, coastal planners must continue to make decisions related to protecting individuals from harm, maintaining public infrastructure, providing government services, and managing natural resources. Communities lack practical tools for identifying hazard exposure to future flooding threats and for identifying partner communities to leverage limited resources. This presentation will summarize current efforts in California to better characterize community-level impacts of coastal flood hazards in the context of what could be applied in the Salish Sea region. Efforts include the Hazard Exposure Reporting and Analytics (HERA) dynamic web application that provides coastal planners with the ability to examine community-level variations in flood-hazard exposure of populations, land cover, infrastructures, and economic assets based on various sea level rise and storm assumptions. Flood-hazard zones were created using the Coastal Storm Modeling System (CoSMoS), which is the modeling framework being refined for the Puget Sound Coastal Storm Modeling System (PS-CoSMoS) to predict coastal flooding and shoreline impacts in the Salish Sea region through the year 2150. In addition to hazard exposure estimates for individual jurisdictions, statistical cluster analysis was completed to identify community similarities across the San Francisco Bay region. This clustering approach serves as a data-driven foundation to help communities identify other communities with similar adaptation challenges and to enhance regional efforts that aim to facilitate resilience through adaptation planning and investment prioritization. This presentation will provide an overview of coastal-flood-hazard exposure and clustering efforts in California, as well as discussion of application in the Salish Sea region to support coordinated investments and cost-benefit analyses of hazard mitigation and habitat management opportunities.
