Oscar Romo from the Tijuana River Estuary took some time to take the Missus and myself around the parts of the Estuary that border Mexico. I will break up the information so that I can give each scale its proper commentary. First up: the watershed scale. At this scale the site sits on the northwest corner. Although the site area looks right down insignificant at this scale, it is important to the river because it sits 400 ft high on a Canyon right were the Tijuana river meets the Pacific Ocean.

The problem is that development pressures on the Los Laureles Canyon have created a situation in which sewer, trash, and soil are rolling down the canyon, altering the Estuary's fragile salt marshes (seen above) and ecosystem.
However, solving this problem becomes harder as the border is currently a political football with the calls for 'closed borders' translating into projects that further damage ecosystems and discourage cross-border solutions.

This project is two unite two hills so that border patrol does not have to drive up and down. The problem is that they are creating a dam that can cause sewer floods on the Mexican side, perhaps worsening the environmental condition of the canyon.
