Abstract
Abstract. One of the key priorities for disaster risk reduction is to ensure
decision makers, stakeholders, and the public understand their exposure to
disaster risk, so that they can take protective action. Flood maps are a
potentially valuable tool for facilitating this understanding of flood risk,
but previous research has found that they vary considerably in availability
and quality. Using an evaluation framework comprising nine criteria grounded
in existing scholarship, this study assessed the quality of flood maps
available to the public in Canadian communities located in designated flood
risk areas. It found that flood maps in most municipalities (62 %) are
low quality (meeting less than 50 % of the criteria) and the highest score
was 78 % (seven of nine criteria met). The findings suggest that a more concerted
effort to produce high-quality, publicly accessible flood maps is required to
support Canada's international commitment to disaster risk reduction. Further
questions surround possible weighting of quality assessment criteria, whether
and how individuals seek out flood maps, and how flood risk information could
be better communicated using modern technology.
