Transportation Sustainability Program

San Francisco is growing. The Association of Bay Area Governments projects that the City will add as many as 190,000 jobs and 100,000 homes by 2040. Much of this is already occurring – projects to create housing for up to 60,000 new people are currently under review or in construction. It is possible to grow smartly, but we must start now.

More housing and jobs means more people using our roads and public transit, further straining our transportation system. Our streets are already crowded and in need of repair. Transit lines are already at or near capacity with record numbers of riders on Muni, BART and Caltrain. Ridership on Caltrain has grown by 60 percent in the last decade alone, and ridership on Muni is projected to increase by 300,000 trips per day, or 43 percent, by 2040.

If we don’t change our development practices and invest in transportation improvements citywide, we can expect unprecedented gridlock on our streets and crowding on our buses and trains.  Without enhancements to our transportation network, we’ll add more than 600,000 cars on our streets by 2040. That’s more than all the cars traveling each day on the Bay and Golden Gate bridges combined.

Imagine all those cars – 600,000 of them – on City streets every day, in addition to the hundreds of thousands you see now.

It doesn’t have to be that way. We can make our City more livable by improving the way we address development. Requiring developers to pay their fair share for transportation impacts will give us the resources and tools to improve public transit, enhance safety for people walking and biking, and better manage vehicular traffic.

The Transportation Sustainability Program is about keeping people moving as our City grows. Smart planning and investment will help ensure that we’re able to arrive safer and more comfortably at our destinations now and in the future.  

What Will the Program Do?

The Transportation Sustainability Program is made up of three components:



Enhance Transportation to Support Growth

Fund citywide transportation improvements, like more Muni buses and trains, to help accommodate new residents and jobs. Find out more >


Modernize Environmental Review

Make the review process align with the City’s longstanding environmental policies by changing how we analyze the impacts of new development on the transportation system under the California Environmental Quality Act (CEQA). The new practices will be more reliable and emphasize travel options that create less traffic. Find out more >


Encourage Sustainable Travel

Make it easier for new residents, visitors and workers to get around through methods other than driving alone by integrating environmentally friendly travel into new developments. New practices will provide on-site amenities so people have better options than driving their car by themselves, such as car sharing and shuttle services. Find out more >
