About 300 volunteers from both sides of the U.S.-Mexico border hauled more than six tons of trash out of the Tijuana River Valley last weekend. Volunteers want to help prevent flooding this winter and keep trash from washing out to sea.
Surfers, ranchers, U.S. Navy Seals, students and volunteers from Tijuana pulled around 600 tires out of San Diego's Tijuana River Valley. They filled two 40-foot-long dumpsters with trash.
Ben McCue is with the conservation group Wildcoast that helped organize the clean up. He says the volunteers even dragged out a few refrigerators.
"Everything we hauled out would have been swept down further into the estuary and into the ocean eventually with the next big rain."
Rain washes garbage from Tijuana neighborhoods that don't have garbage collection across the border into the Tijuana River Valley.
The waste combined with sediment blocks drainage channels. Last winter, that caused flooding.
There's worry the newly built border fence could exacerbate flooding this winter by depositing more sediment in drainage channels.
