Los Angeles Times: Should L.A. look to 'sponge cities' to solve its flooding problem?
The Los Angeles Times article explores whether Los Angeles should adopt the “sponge city” approach to address its persistent flooding problems. Sponge cities use natural systems—such as wetlands, permeable surfaces, and green infrastructure—to absorb, store, and manage stormwater, contrasting with traditional gray infrastructure that quickly channels water away. Given increasing rainfall intensity due to climate change, sponge city strategies offer multiple benefits including flood reduction, groundwater recharge, improved water quality, and urban cooling. Examples from global cities and local successes in Los Angeles demonstrate the feasibility and advantages of integrating sponge infrastructure. While challenges remain in retrofitting existing urban areas, expanding green roofs, permeable pavements, and urban wetlands presents a promising, nature-based solution for L.A.’s climate resilience and water management future.
