Los Angeles city officials hope to create jobs with a Downtown cluster of environmentally sustainable companies at a currently 20 acre parcel in an industrial area south of the 10 freeway near Santa Fe Avenue.  Up to 1 million square feet of buildings could accommodate such businesses at the site.  Tax breaks and other financial incentives will be offered.  The Community Redevelopment Agency (CRA) will be shopping the proposal to different businesses.  The site was once a bus manufacturing facility.
