Setting El Niño aside, the Los Angeles area is prone to periods of drought, it is imperative to create landscapes that are able to capture and store as much rainwater and runoff as possible, whether it’s rain from a few small storms or a devastating El Niño.
The best way to capture water is through passive rainwater harvesting in the form of swales and rain gardens. To see a great example of a passive rainwater system, check out the Crescent Farm at the Los Angeles County Arboretum.
Rain barrels and cisterns are an additional active rainwater harvesting option to capture and store even more rain in preparation for drier times.
Even if El Niño brings as much rain as expected, preparation for our current and future droughts needs to start now.
