Proposition 4 - US Mexico Border Grant Program

Background

The Safe Drinking Water, Wildfire Prevention, Drought Preparedness, and Clean Air Bond Act of 2024 (Prop 4) was approved by California voters in the general election on November 4, 2024. Among other funds, Prop 4 provided $50 million for grants to projects that will address water quality problems arising in the California-Mexico cross border rivers and coastal waters. Prop 4 allows up to seven percent (7%) for administrative cost and there are additional statewide bond costs. After accounting for these costs, there is $46,151,000 available for eligible projects.
