An ambitious, long-in-the-works project to turn one of the largest remaining parcels of undeveloped land in South Florida into a planned community just took a step closer to fruition.

Wells Fargo & Company has made a $101 million HUD-insured loan to SM Multifamily LLC, the developer of two luxury, 17-story residential towers with a total of 400 units and attached parking garage.

The towers will be part of the first phase of SoLeMia Miami, the 183-acre master-planned community in North Miami being developed by Oleta Partners LLC.

Since the 1960s, various attempts to develop the land parcel have failed. Previous plans for the site formerly known as Biscayne Landing have included an amusement park and indoor ski resort. From 1975 to 1981, the tract was used as a municipal landfill. Oleta Partners acquired the property in 2015.

When completed, SoLeMia is expected to include more than 4,300 residential units, a hotel, a 10-acre lagoon, beaches, shops and restaurants. The entire project is expected to take 15 years and two development cycles to fully build out.
