New California Law Bolsters Groundwater Recharge as Strategic Defense Against Climate Change

A new but little-known change in California law designating aquifers as “natural infrastructure” promises to unleash a flood of public funding for projects that increase the state’s supply of groundwater.

The change is buried in a sweeping state budget-related law, enacted in July, that also makes it easier for property owners and water managers to divert floodwater for storage underground.
