A Record of Decision has been issued by the Service selecting the preferred alternative restoration plan in the final environmental impact statement for the Otay River Estuary Restoration Project. This 125-acre project is partial mitigation for the Carlsbad Desalination Plant. We expect to break ground on the restoration project in fall of 2019.
