With all of the excitement over new high-rises in South Park, you may have forgotten about some of Downtown's mixed-use developments that aren't rewriting the skyline.  Perhaps it's time for a refresher.  When we checked in on Ava Little Tokyo last Fall, construction on the TCA Architects designed project had just progressed above podium level.  Flash forward to 2014, and both of its six-story structures are topped out, with exterior work underway at 2nd and Los Angeles Streets.  When Avalon Bay's two building project opens between late 2014 and early 2015, it will create a combined 280 residential units above 20,000 square feet of ground floor retail space.  Outdoor amenities will include landscaped courtyards and a rooftop chill lounge (check out renderings from the MJS Design Group below).  Also under construction next-door is a 240-unit development from the Irvine-based Sares-Regis Group.  These two TCA-designed projects will finally complete the re-development of Little Tokyo's Block 8, formerly home to acres upon acres of parking lot blight.  A residential mid-rise is also planned across the street by the Malibu-based Weintraub Real Estate Group.  The nine-story mixed-use building, dubbed the Vibiana Lofts, would create 238 new apartments and help bridge the gap between Little Tokyo and the Historic Core.
