San Joaquin County is moving toward a cleaner, healthier future. The San Joaquin Council of Governments (SJCOG) Board of Directors has approved $25.4 million in funding for 11 innovative projects aimed at improving air quality and transportation efficiency across the region.

From replacing diesel buses with electric vehicles to clearing the most congested rail intersection in California, the funded projects will benefit everyone who breathes and moves in San Joaquin County.

“This funding package is a perfect example of how regional planning can deliver big benefits at the local level,” said SJCOG Executive Director Diane Nguyen. “Each project was selected because of its ability to reduce harmful emissions and make daily travel cleaner, safer, and more efficient for San Joaquin County residents.

Projects receiving Congestion Mitigation and Air Quality (CMAQ) funds include adding and coordinating traffic signals, installing electric vehicle charging stations, new electric transit minibuses, street improvements, hydrogen refueling trailer for transit buses, and work to clear up the most congested rail intersection in the state.

“These projects aren’t just about reducing emissions. They’re about improving everyday life for people across our communities,” said Lathrop Mayor and SJCOG Board Chair Paul Akinjo. “By making smart investments in cleaner transportation, we’re giving families healthier air to breathe and better options for getting where they need to go.”

The projects funded with the $25.4 million are:

  • Replace two transit vehicles with two electric minibuses, Escalon: $640,000
  • Add right-turn lane on Lathrop Road to access Interstate 5, Lathrop: $1.6 million.
  • Citywide signals coordination, Manteca: $700,000.
  • Electric vehicle charging at City Hall, Manteca: $690,534.
  • Solar powered EV charging at City Hall, Mountain House: $1.4 million.

  • Feather Drive and Driftwood Place roundabout, Stockton: $2.9 million.
  • MacArthur Drive and Schulte Road signal interconnect: $1.5 million.
