Climate change is creating more extreme conditions, leading to longer dry periods and more intense storms. Most of the city’s stormwater is managed through an extensive network of concrete street gutters, storm drains, and flood control channels, with the flows being directed out to the Pacific Ocean. This network of “grey infrastructure” was established in response to early-20th-century floods, which severely damaged property adjacent to the LA River and its tributary streams. Over time, this network of grey infrastructure led to the serious reduction of natural groundwater recharge. Meanwhile, models suggest that precipitation within the region will likely become flashier, heightening flood risk. These conditions were exacerbated by the extensive urbanization that took place across the county during the second half of the 20th century, replacing water-absorbing landscape with impervious surfaces like concrete, asphalt, and turf grass. Today, LA’s water management and aging infrastructure are considered increasingly precarious, due to a number of environmental, legal, and political stressors. (Perisho, Randle, Winter, 2018).
