Notwithstanding its protected status as a listed species under the federal Endangered Species Act, the Southern California steelhead population is proposed for listing under the California Endangered Species Act. During a time of unprecedented drought and storm activity resulting from climate change, this move to list the species in California is likely to have major impacts on the provision of water and recycled water supply, flood control and storm water treatment and management. In the latest episode of Digging Into Land Use Law, Nossaman Environment & Land Use partner Mary Lynn Coffee and Water partner Lori Anne Dolqueist discuss the California Endangered Species Act listing process, the potential effects of a listing on public health and safety activities and regulatory tools available to streamline approvals for such activities if a listing is adopted.
