The California State Water Resources Control Board now has rules for distributing nearly $50 million in state bonds for water quality projects that could help fix pollution in the Tijuana and New rivers. Leaders in San Diego and Imperial counties had been making their case for why their regions should receive the full amount of funding that Proposition 4 earmarked to clean up rivers and coastal waters near the California-Mexico border. Proposition 4, which California voters approved in November 2024, however, did not specify who would get the funding and how much. On Tuesday, board members unanimously approved a process to decide.
