The site of a shuttered post office in Koreatown could be redeveloped as a mixed-use complex. Yesterday, local developer Urban Commons filed plans with the City of Los Angeles to construct a 10-story building at 6th and Harvard Streets, creating up to 44 residential units, 200 hotel rooms and 18,000 square feet of ground- and second-floor retail space. The project would offer a mixture of one- and two-bedroom apartments, as well as guest amenities and a three-level underground parking garage. The development site is currently occupied by a one-story commercial building and an adjoining surface parking lot. Both would be demolished for the project. Additional details are currently unclear. Urban Commons, based out of Los Angeles, is also leading the effort to redevelop the expansive parking lots which surround the Queen Mary in Long Beach.
