Public Attitudes Toward Policy Instruments for Flood Risk Management.

Effective flood risk management (FRM) requires a mix of policy instruments that reduces, shares, and manages flood risk. The social acceptability of these policy instruments-the degree of public support or opposition to their use-is an important consideration when designing an optimal mix to achieve FRM objectives. This paper examines public attitudes toward FRM policy instruments based on a national survey of Canadians living in high-risk areas. Respondents were asked their views on flood maps, disaster assistance, flood insurance, flood risk disclosure and liability, and property buyouts. The results indicate that all five policy instruments have high social acceptability, but they must be calibrated to ensure access to flood risk information and achieve a fair distribution of FRM costs among key stakeholders.

Assessing social vulnerability and identifying spatial hotspots of flood risk to inform socially just flood management policy.

This study presents the first nationwide spatial assessment of flood risk to identify social vulnerability and flood exposure hotspots that support policies aimed at protecting high-risk populations and geographical regions of Canada. The study used a national-scale flood hazard dataset (pluvial, fluvial, and coastal) to estimate a 1-in-100-year flood exposure of all residential properties across 5721 census tracts. Residential flood exposure data were spatially integrated with a census-based multidimensional social vulnerability index (SoVI) that included demographic, racial/ethnic, and socioeconomic indicators influencing vulnerability. Using Bivariate Local Indicators of Spatial Association (BiLISA) cluster maps, the study identified geographic concentration of flood risk hotspots where high vulnerability coincided with high flood exposure. The results revealed considerable spatial variations in tract-level social vulnerability and flood exposure. Flood risk hotspots belonged to 410 census tracts, 21 census metropolitan areas, and eight provinces comprising about 1.7 million of the total population and 51% of half-a-million residential properties in Canada. Results identify populations and the geographic regions near the core and dense urban areas predominantly occupying those hotspots. Recognizing priority locations is critically important for government interventions and risk mitigation initiatives considering socio-physical aspects of vulnerability to flooding. Findings reinforce a better understanding of geographic flood-disadvantaged neighborhoods across Canada, where interventions are required to target preparedness, response, and recovery resources that foster socially just flood management strategies.

Evaluating the quality of municipal strategic plans.

Local governments increasingly use strategic planning as a tool to anticipate and address the complex challenges they face. Strategic planning is the process of setting long-term goals, prioritizing actions to achieve the goals, and mobilizing human and financial resources to execute the actions. Although there has been considerable debate about the appropriate scope, content, and procedures for strategic planning in local government, less attention has been paid to the quality of municipal strategic plans, meaning the presence or absence of key characteristics that analysts typically associate with good plans. This article explores the content and quality of municipal strategic plans in Canada. It presents results of a comparative plan quality evaluation, which assessed the official strategic plans of the 66 most populous Canadian municipalities using a comprehensive set of criteria derived from existing scholarship on plan quality and strategic planning. The findings indicate that there is considerable room to improve municipal strategic plans, which lack many of the features commonly associated with good quality plans. Municipal strategic plans should contain a comprehensive fact base to prioritize and rationalize the goals within the plan, and there should be appropriate provisions for implementing, monitoring, and evaluating plan progress and outcomes.

Exploring spatial heterogeneity and environmental injustices in exposure to flood hazards using geographically weighted regression.

This study explores flood-related environmental injustices by deconstructing racial, ethnic, and socio-demographic disparities and spatial heterogeneity in the areal extent of fluvial, pluvial, and coastal flooding across Canada. The study integrates JBA Risk Management's 100-year Canada Flood Map with the 2016 national census-based socioeconomic data to investigate whether traditionally recognized vulnerable groups and communities are exposed inequitably to inland (e.g., fluvial and pluvial) and coastal flood hazards. Social vulnerability was represented by neighbourhood-level socioeconomic deprivation, including economic insecurity and instability indices. Statistical analyses include bivariate correlation and a series of non-spatial and spatial regression techniques, including ordinary least squares, binary logistic regression, and simultaneous autoregressive models. The study emphasizes the quest for the most appropriate methodological framework to analyze flood-related socioeconomic inequities in Canada. Strong evidence of spatial effects has motivated the study to test for the spatial heterogeneity of covariates by employing geographically weighted regression (GWR) on continuous outcome variables (e.g., percent of residential properties in a census tract exposed to flood hazards) and geographically weighted logistic regression on dichotomous outcome variables (e.g., a census tract in or out of flood hazard zone). GWR results show that the direction and statistical significance of relationships between inland flood exposure and all explanatory variables under consideration are spatially non-stationary. We find certain vulnerable groups, such as females, lone-parent households, Indigenous peoples, South Asians, the elderly, other visible minorities, and economically insecure residents, are at a higher risk of flooding in Canadian neighbourhoods. Spatial and social disparities in flood exposure have critical policy implications for effective emergency management and disaster risk reduction. The study findings are a foundation for a more detailed investigation of the disproportionate impacts of flood risk in Canada.

How Flood Experience and Risk Perception Influences Protective Actions and Behaviours among Canadian Homeowners.

Canada is a country in the midst of a flood management policy transition that is shifting part of the flood damage burden from the state to homeowners. This transition-as well as the large financial losses resulting from flooding-have created a window of opportunity for Canada to implement strategies that increase property owners' capacity to avoid and absorb the financial and physical risks associated with flooding. This work presents foundational research into the extent to which Canadians' flood experience, perceptions of flood risks and socio-demographics shape their intentions and adoption of property level flood protection (PLFP). A bilingual, national survey was deployed in Spring 2016 and was completed by 2300 respondents across all 10 Canadian provinces. The survey was developed using assumptions in existing literature on flood risk behaviours and the determinants of flood risk management in similar jurisdictions. The paper argues that property owners are not willing to accept greater responsibility for flood risk as envisioned by recent policy changes. This finding is consistent with other OECD jurisdictions, where flood risk engagement strategies have been developed that could be replicated in Canada to encourage risk-sharing behaviour.
