With so many transportation agencies in the Bay Area, different entities often end up planning and building pieces of the same project. That’s happening right now on a grand scale: There are no less than five megaprojects taking place between San Jose and Oakland. If planned right they could add up to much more than the sum of their parts.

What would it look like if we put people at the center of transit planning — if we designed a friendly system grounded in the needs, wants and preferences of all riders? Would transit be more useful? Would more people ride it? To help transportation planners understand riders as customers, SPUR recently hosted the third annual Transit + Design Workshop.

Over the next decade, more than $10 billion of transportation investments will start to remake San Jose’s Diridon Station into the first high-speed rail station in the country and the busiest transportation hub west of the Mississippi. This historic opportunity has the potential to reshape the entire South Bay. SPUR proposes seven principles that should guide planning, land use and transportation decisions at Diridon.

Last month, San Francisco Mayor Ed Lee signed the HOME-SF program into law. The new law encourages housing developers to provide 30 percent of new units to low- and moderate-income households in exchange for permission to build bigger. The program will help to fill San Francisco’s growing need for housing, particularly for middle-income households that have not been well-served in the past.

As the pace of residential development picks up in downtown Oakland and the Broadway-Valdez area, it’s worth remembering that Oakland is much, much bigger than those two small neighborhoods and that very little is being built anywhere else. If we really want to alleviate the housing shortage, we need to build much more housing, in many more parts of the city.
