Restoring the LA River: Is the Latest Plan Big Enough? The Los Angeles River runs for 32 miles through the City of LA, in a concrete flood control channel that the Army Corps of Engineers started to build in the 1930's. In recent decades, there's been pressure for restoration. Now the Corps has reduced 152 plans down to four, ranging from $346 million to $1 billion. The Corps is recommending Alternative 13, on the lower cost side, which would restore water flow and habitation on parts of 11 miles of the river.
