There have been plans proposed to revitalize the river. The project aims to protect wildlife which lives near and within the river and to bring back the river to its healthy state.

There was a 20 year blueprint for management and development of the Los Angeles River included on the revitalization planning among involved people. And this plan was officially adopted in May 2007 by the City of Los Angeles.
