OPC Proposition 4 Coastal and Ocean Resilience Grant Program


On November 5, 2024, California voters approved the Safe Drinking Water, Wildfire Prevention, Drought Preparedness, and Clean Air Bond Act of 2024, also known as the 2024 Climate Bond or Proposition 4 (Public Resources Code sections 90000 to 95015). Proposition 4 allocates the following to OPC:

  • $135 million for projects that conserve, protect, and restore marine wildlife and healthy ocean and coastal ecosystems (Public Resources Code section 92020)
  • $75 million to implement the California Sea Level Rise Mitigation and Adaptation Act of 2021 (Senate Bill 1, Atkins) (Public Resources Code section 92030)

OPC has also received separate appropriations to administer funding for Public Resources Code section 92050 through the Budget Act of 2025 to protect and restore island ecosystems, advance climate-ready fisheries, and support the restoration and management of kelp ecosystems.
