Los Angeles County has kicked off the environmental review process for the Vermont Corridor project, giving us a chance to learn new details about the proposed redevelopment of several dilapidated properties in Koreatown.

Trammell Crow Company, which was selected as the project's developer last August, is expected to construct a mixture of government offices, apartments and ground-level commercial space on three sites along Vermont Avenue just north of Wilshire Boulevard.

The first property - located to 510-532 S. Vermont Avenue - is currently improved with a vacant County office building.  Plans call for razing the existing structure and redeveloping the property as a 21-story tower featuring 471,000 square feet of office space above 10,000 square feet of ground-floor retail space and parking for 965 vehicles.  The 296-foot tall building was designed by Gensler as of last year.

Immediately south, an existing 12-story County office building would be converted into a mixture of studio, one- and two-bedroom apartments featuring 4,100 square feet of ground-floor retail space and a rooftop deck.  The adaptive reuse project, designed by Steinberg Architects, would reclad the mid-century building with glass.

The redevelopment of the second property would also requre the demolition of a second office building next-door, which would be replaced by a five-story parking structure.  The proposed garage would be built to allow for the future development of five residential levels above, featuring up to 74 apartments.

The third property, located at 427-433 S. Vermont Avenue, features an additional County office building.  Plans call for the demolition of this low-rise building, followed by the construction of a six-story edifice featuring 100 units of senior affordable housing - catering to homeless adults.  Plans also call for three levels of underground parking and a 13,000-square-foot community center.

While the environmental review process for the $450-million development gets underway, Trammell Crow Company and L.A. County are scheduled to continue negotiating a ground-lease for the properties.  A full agreement has been previously expected by Aril 2018.
