Frank Gehry is said to be “quietly” working on a masterplan for the Los Angeles River in California. Prematurely announced by the Los Angeles Times, the City’s mayor Eric Garcetti has confirmed the news, saying Gehry is producing “a master plan, in the truest sense of the word,” pro bono.

“To have the [Frederick Law] Olmsted of our time focusing on this, I think, is extraordinary,” Garcetti said, according to the Los Angeles Times.

Beyond the expected revival of public areas, bridges, new walkways and bike paths, little details regarding the 51-mile masterplan have been release. This leaves some concerned about the scheme’s lack of public input. However, according to a statement provided by the city, the “project will have a tremendous amount of public input from the diverse talent and ideas of people across the region.”

Garcetti and the L.A. River Revitalization Corp., a nonprofit charged with coordinating the river’s renewal, had not planned on announcing Gehry’s contribution until later this month.
