Officials met in Imperial Beach Friday to discuss the sewage pollution that continues to plague South Bay shorelines — shuttering beaches more than 100 days every year. The event was billed as an “inaugural dialogue,” which in the future will include a host of other binational issues, including climate change and commerce. Assemblyman Todd Gloria (D-San Diego) and others met on Friday with Baja California officials to discuss future collaboration on how to address Tijuana’s lack of wastewater infrastructure and the potential for California to help with funding. “It’s a statewide concern elevated at the highest levels of state government,” Gloria told a crowd of concerned residents and elected officials, largely from Imperial Beach and Coronado.
