Abstract

Significance: As sea levels rise, coastal cities will rely on shoreline protection strategies such as levees and seawalls to mitigate flooding. Although these strategies provide local flood-reduction benefits, they can increase inundation along other shorelines within the same estuary or bay. Using hydrodynamic and economic models, we quantify previously unmeasured regional economic damages (up to $723 million per flood event) that result from the protection of individual shoreline segments in San Francisco Bay, CA. We also highlight and quantify opportunities to alleviate regional flood damage through strategic floodwater storage in low-lying areas. Integrating the findings into coordinated planning efforts that account for the regional impacts of local shoreline actions could provide opportunities to reduce shared risk in coastal regions globally.

  • Low-income renters of color are more likely to live in housing that is older, substandard, and less maintained; these quality issues increase the risk of structural collapse and damage to people and properties during extreme weather events.

    “In addition to the environmental effects of the construction materials, low-income renters of color are more likely to live in housing that is older, substandard, and less maintained; these quality issues increase the risk of structural collapse and damage to people and properties during extreme weather events.[175][176][177][178][179]”

    The Discussion describes flooding impacts on BIPOC residents and notes that they often have fewer resources to prepare for and recover from flooding. Materials and Methods > Economic Damages estimates repair costs for flooded buildings. Neither section addresses whether low-income renters of color live in older or less-maintained housing, or whether those housing conditions increase structural-collapse risk; searches for those terms found no such passage.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
