The border cities of San Diego and Tijuana comprise the largest bi-national metropolitan region in the world. But while they have roughly equal populations, San Diego has sprawled approximately six times larger thanTijuana in the last decades.

The radical proximity of wealth and poverty in this border region provides an urgent backdrop against which new collaborative models of equitable economic growth and climate resilience can be developed and tested. The unplanned development on the Tijuana side, as well as the lack of means to control such irregular settlements, has made it more difficult for the government to provide needed infrstructture and services.

The project of a Network for Civic Nodes inTijuana Canyon suggests a possible transformation and revitazilaton of the river watershed through the creation of public spaces.
