International Border Community

The International Border Community encompasses parts of San Ysidro and Otay Mesa East. It was added to the Community Air Protection Program (CAPP or AB 617) by the California Air Resources Board (CARB) in 2022. 

Adjacent to Tijuana Mexico and located on unceded Kumeyaay territory, San Ysidro and Otay Mesa East are vibrant and culturally rich Tri-National communities with art, music, food, commerce, and people flowing back and forth across the border. But due to planning and infrastructure that has favored passenger vehicles and unsustainable commerce activities, this cross-border exchange comes at a cost to the environmental health of the communities on both sides of the border.  

Community Priorities

The following list highlights some of the air quality priorities identified by the Community Steering Committee: (Note, it is not an exhaustive list of community-identified air quality priorities.)  

  • Actions that protect children, elderly, chronically ill, and other groups that are vulnerable to air pollution.  

  • Idling cars at the ports of entry.  
  • Traffic circulation near or around Las Americas Premium Outlets, Dairy Mart Rd., Calle Primera, Willow Rd., Camino De La Plaza, East San Ysidro Blvd., and more.  

  • Idling heavy duty trucks at the port of entry.  
  • Operations at warehouses, including current and proposed expansions.  
  • Current and future impacts to people living in new housing developments near freeways and warehouses, especially along California State Route 905.  

  • Dust and exhaust from Border Patrol ATVs and vehicles operating on the west side of San Ysidro. Emissions from freight trains going through the heart of San Ysidro.  
  • Pollution from both Brown Field Municipal Airport in Otay Mesa and Aeropuerto Abelardo L. Rodriguez in Tijuana.  

  • Odor from the Tijuana River caused by untreated sewage flowing from Tijuana.  
  • Trash and other items being burned in Tijuana.  
  • Industrial-related emissions coming from Tijuana.
