Back in January, news of a supportive housing project adjacent to the Gold Line's Indiana Station was met with hostility from Boyle Heights residents.  Hopefully a proposed transit oriented development next to Soto Station will get a warmer response.  According to a recent case filing with LADCP, plans are in the works for a 64,000 square foot mixed-use structure near the intersection of 1st and Soto Streets.  Rising six stories, the project would consist of 50 residential units, 3,400 square feet of street level commercial space, and 8,500 square feet of office space on its top floor.  Residential and commercial tenants would be served by a 70-vehicle garage, most of which would be located underground.  Occupying three parcels between 2407 and 2421 E. 1st Street, the project will require the demolition of several existing residential structures, some of which date back to the late 19th century.  Although a six-story building would tower over the mostly low slung Boyle Heights neighborhood, 2407 E. 1st Street may be in store for neighbors of a similar scale in the near future.  Metro is currently soliciting bids for a mixed-use development to be built on their 1.4 acre property on the opposite side of the intersection.
