The southernmost portion of the U.S., from Los Angeles to Jacksonville, offers a compelling window on what lies ahead for the nation. On the front lines of social, economic, and climate change, the Ten Across region contains the three most populous states, many of the largest and most rapidly growing metro areas, the energy capital of the world, many of the largest American international ports, extremes in weather and water-related challenges, and great diversity and demographic change.

Here, more than any other cross section of the country, a new and critical portrait of the future can be seen.

Ten Across convenes diverse perspectives to better share information and to inspire proactive decision-making for resilience and sustainability.

Together with our growing network, we engage this region as a living laboratory through which to understand and cultivate more effective responses to the known future.

Ten Across is propelled by 3 questions:


How do
we know?

Ten Across draws on both the lived experience of individuals throughout this transect and established sources of scientific data to find insights into our present and the future of the U.S.


What do
we know?

The evidence to be seen throughout this region tells us that change is accelerating, and that our choices and values are undeniably reflected in both our built and natural environment.


What future
will we choose?

The modern ability to measure and communicate our circumstances brings unprecedented knowledge of the future—and with it, a great responsibility. Our awareness obliges us to act in favor of a more resilient and sustainable future.


Our mission is to advance resilience by building connections and sharing information across and beyond this critical region of the country. The work, experiences, and stories to be found here on the leading edge of change have the power to inform the rest of the nation.

Our greatest challenges defy conventional boundaries between places and professions—so must our solutions.

Ten Across is a reflection of the most innovative university in the US, Arizona State University—one which is built around a national mission. Founded in 2017 by Wellington “Duke” Reiter, FAIA, Ten Across collaborates in the cultivation of understanding of the people, places and challenges throughout our unique and varied region, and creates opportunities to share the expertise necessary to drive transformative change.
