Hurricane Harvey, a category 4 hurricane, made landfall on Texas and Louisiana in August 2017, causing catastrophic flooding and 80 deaths and inflicting $125 billion  in damage, of which $67 billion  was attributable to climate change . Several studies estimated the return period of the rainfall associated with this event and assessed that human-induced climate change increased the likelihood by a factor of approximately three using a combination of observations and climate models . The impacts of Hurricane Harvey were exacerbated by extensive residential development in flood-prone locations. A study showed that urbanisation increased the probability of such extreme flood events several folds  through the alteration of ground cover and disruption and redirection of water flow. Water quality in cities also deteriorated , and 85% of flooded land subsided at a rate of 5 mm yr-1 following the event . Notably, the impacts of Harvey were unequally distributed along racial and social categories in the greater Houston area. Neighbourhoods with larger Black, Hispanic and disabled populations were the worst affected by the flooding following the storm and rainfall . In addition, racial and ethnic disparities were shown to impact post-disaster needs, ranging from household damage to mental health and recovery .
