Tijuana River, Sweetwater, Otay and Pueblo watersheds—with a focus on the Tijuana River Valley floodplain (located in the lower Tijuana River Valley/U.S.). The 5,000 acre floodplain is a sub-section of the Tijuana River Watershed, a 1,750 square mile area that straddles the U.S./Mexico border.  The portal will be extensible to other project locations in the county and across the border.
