After years of dormancy, plans for an expansion of the Medallion complex in Downtown Los Angeles have quietly come back to life.

Last week, an environmental impact report was filed with the Los Angeles Department of City Planning for the second phase of the mixed-use development at 3rd and Main Streets.

According to a 2013 report from the blog DTLA Rising, the project was slated to feature up to 400 residential units in four 13-story towers linked by a skybridge.  Tentative plans from developer Saeed Farkhondehpour also called for 38,000 square feet of retail space, a 24,000-square-foot theater, 25,000 square feet of public green space, a five-level parking garage and potentially a boutique hotel.

However, it is unclear if the four-building design - crafted by Kevin Tsai Architecture - still reflects the current plan for the development.

The first phase of the Medallion, which features 96 residential units and 200 retail spaces, opened in 2010 at the northeast corner of 4th and Main Streets.

The revived second phase of the development would rise one block south of a recent series of similar developments in the Little Tokyo neighborhood, including an eight-story apartment complex adjacent to the deconsecrated Cathedral of St. Vibiana.
