Last week I attended a tour of the Tijuana River Valley, organized by 11 organizations for the 30×30 Partnership Summit, a statewide meeting of groups committed to achieving California’s conservation goals. … A vast array of entities oversee and advocate for the river valley. On the U.S. side alone, the land is stewarded by federal, state, county and city agencies. Advocacy groups with a stake in the river’s future — and in resolving the public health crisis caused by billions of gallons of untreated wastewater pouring into the watershed — hail from both sides of the border.
