Local governments adopt policies regarding the construction of new homes and the protection of greenspace, and they spend resources on infrastructure projects. When governments adopt policies and invest in infrastructure without considering available information regarding their community’s vulnerability to flooding, many residents find themselves at an increased—and unnecessary—risk. As a result, constituents may miss days of work, experience property damage, lose access to flood insurance, or find themselves with a flood-prone property that they cannot sell.
To evaluate this indicator, we studied data that reveal floodplain development in the six coastal counties most vulnerable to flooding. We also analyzed data regarding community participation in the National Flood Insurance Program’s Community Rating System (CRS), which is a flood risk reduction program.
