One of the largest residential projects currently in development in St. Petersburg will now include affordable housing thanks to financial support from Pinellas County.

On Tuesday, the Pinellas County Commission unanimously approved $5.5 million for the construction of the first phase of Sky Town, which is expected to break ground in March and include 401 apartments, 121 of which will now be affordable.

Sky Town, which is being developed by Coral Gables-based Altis Cardinal, is a massive mixed-use development expected to bring 2,084 apartments across six five-story buildings to 3201 34th Street South in the Skyway Marina District.

The project, which sits on 34.2 acres, will also include over 80,000 square feet of retail space, 22,500 square feet of office space, 4,000 parking spaces, and 119,160 square feet of self-storage space.
