This national analysis identifies the number of US homes at risk from chronic flooding over the coming decades due to sea level rise. It also shows the current property value, estimated population, and portion of the property tax base at risk. Information is available by state, community, and zip code.
Along nearly 13,000 miles of coastline of the contiguous United States, hundreds of thousands of buildings lie in the path of rising seas: schools, hospitals, churches, factories, homes, and businesses. As sea levels rise, persistent high-tide flooding of homes, yards, roads, and business districts will begin to render properties effectively unlivable, and neighborhoods—even whole communities— nancially unattractive and potentially unviable.
Yet property values in most coastal real estate markets do not currently reflect this risk. And most homeowners, communities, and investors are not aware of the nancial losses they may soon face.
This analysis estimates the number of homes and commercial properties throughout the coastal United States that will be put at risk from chronic, disruptive flooding—defined as flooding that occurs 26 times per year or more (Dahl et al. 2017; Spanger-Siegfried et al. 2017)—in the coming decades.
The Action on Climate Today (ACT) programme has been actively working in five South Asian countries to help governments plan for, and manage, the impacts of climate change in the water sector. ACT has championed a Climate-Resilient Water Management (CRWM) approach as a way of increasing the resilience of water systems on which billions of people rely.
This learning paper outlines the core elements of the CRWM framework and provides examples from ACT’s work employing the framework across the region. The methodology has been deployed in South Asia, but will be of relevance to practitioners and policy makers working in water resource management around the world.
This framework is informed by these activities and within this water management interventions are sorted into three categories:
Water resource management (including assessment, supply augmentation and demand management);
Management of extreme events (floods and droughts); and,
Creating an enabling environment for CRWM (including mainstreaming climate impacts in sectoral and cross-sectoral policies, among other governance instruments).

On March 6th, 2018, ACT, SFU and Western University co-hosted a workshop in Vancouver on the topic of climate change adaptation and governance in Canada, with a specific focus on issues relating to the British Columbia (BC) context. Attendees included participants from government, academia, private sector, and non-governmental organizations. Particular attention was given to province-wide strategies for adaptation, risk reduction, and the intersection between them. This workshop was part of a series of events being carried out in tandem with research at Western University.1 This report summarizes the discussion with participants on adaptation framed as a set of actions and governance strategies.
Climate change adaptation is the process of preparing for actual or projected changes in climate averages and extremes. It relies on interpretations and values pertaining to key questions regarding ways hazards and vulnerability are determined; the nature of acceptable interventions; and the determinants of success. As a result, adaptation is both complex and political in nature. The process of identifying the most effective roles for various actors and the best policy instruments to use to reach certain goals is not only value-laden, but complex and uncertain.
In an attempt to untangle this many-faceted issue within the provincial context, participants were asked to consider the following questions:
Based on your experience and professional insight, what are the necessary components for effective climate change adaptation governance in Canada?
Based on existing successes, what roles and mechanisms are required for effective and collaborative adaptation?
What are the barriers to effective adaptation governance, and what are some potential strategies for overcoming them?
In 2012, the Florida Department of Economic Opportunity (DEO) initiated a five-year project to integrate sea level rise adaptation into current planning mechanisms, including the local comprehensive plan, hazard mitigation plan, and post-disaster redevelopment plan. One of the focus areas is to provide statewide guidance on how to implement an Adaptation Action Area at the local level. Through funding from the National Oceanographic and Atmospheric Administration (NOAA) and the Florida Department of Environmental Protection (DEP), DEO engaged the South Florida Regional Planning Council (SFRPC) to assist in the research for Adaptation Action Area implementation strategies. The SFRPC is working with the City of Fort Lauderdale, which is serving as one of the state's Adaptation Action Area pilot communities, and Broward County to test adaptation policy options to be incorporated into the City's Comprehensive Plan. This report is part of a portfolio of resources developed during the Community Resiliency Initiative, a five-year project funded by NOAA through the Florida Department of Environmental Planning’s Florida Coastal Office and carried out by the Florida Department of Economic Opportunity. The Community Resiliency Initiative focused on coordinating planning efforts throughout the State and integrating sea level rise adaptation into existing planning mechanisms, including local comprehensive plans, local hazard mitigation plans, and disaster redevelopment plans. The Community Resiliency Initiative worked to examine existing data and practices related to current sea level rise adaptation planning efforts and develop guidance for agencies and communities to consider as they plan for and implement adaptation strategies.
