An application was submitted to the Federal Aviation Administration last month to build a 750-foot apartment tower at 400 Biscayne Boulevard.
According to the filing, the the building would top off at 740 feet above ground, or 750 feet above sea level. The application was submitted on June 12.
The FAA filing is one of several steps that developers PMG and Greybrook are taking to prepare for groundbreaking.
Last week, a Declaration of Restrictive Covenant in Lieu of Unity of Title was recorded with the county for the property, after being filed with the city. It allows the developers to obtain a construction permit.
Also last month, a partnership between developers PMG and Greybrook secured utilities from Miami-Dade County for 704 apartment units to be built at the site.
If built at 740 feet, it would become one of the top five tallest buildings in Miami, surpassing the under-construction One Thousand Museum tower.
