As the Los Angeles River bends into the vast industrial district east of downtown Los Angeles, it looks less like a waterway than a decaying open-air canvas for taggers.
This largely hidden channel that runs through two rail yards is what authorities describe as the ultimate proving ground for graffiti vandals vying for visibility and reputation.
This is not the graffiti you see in alleyways and storefronts. This is tagging on steroids, with monikers big and bold, containing letters that often are as big as garage doors.
The centerpiece is something officials say is the biggest tag they've ever seen: Three block letters that cover a three-story-high wall and run the length of several blocks between the 4th Street and 1st Street bridges. It spells out "MTA" -- Metro Transit Assassins.
These huge graffiti projects take paint rollers, not spray cans.
Some of the most elaborate tags take days, said Sheriff's Deputy Devin Vanderlaan. He points to one that is big enough to be a front lawn and is just an outline. "They are going to come back and finish that one," he said.
Authorities allege that this was a favorite spot for "Buket," allegedly one of L.A.'s most prolific taggers, who was arrested earlier this week.
On Tuesday, L.A. County prosecutors charged 24-year-old Cyrus Yazdani with nearly three dozen counts of felony vandalism, accusing him of spraying his "Buket" moniker on dozens of locations around the county. Yazdani is accused of tagging freeway signs and buses, his work videotaped and shown on YouTube.
Los Angeles County sheriff's deputies and officials with the U.S. Army Corps of Engineers have identified at least 20 "Buket" scrawlings along a stretch of the river spanning a couple of miles, causing an estimated $60,000 in damage.
Cleaning graffiti from the river is far more expensive than cleaning other areas. Officials use high-pressure water spray to remove the toxic paint. But hazardous-material crews must then dam and capture all the paint and water runoff to prevent it from getting into the riverbed.
Roland Gonzales, with the Army Corps of Engineers, estimates that the price tag for cleaning the roughly two miles of concrete walls could reach half a million dollars.
"We can paint today and they'll be back here tomorrow," Gonzales said. "It is a fresh canvas for them. . . . They will be right behind you."
