Notice of Intent To Release Certain Properties From All Terms, Conditions, Reservations and Restrictions of a Quitclaim Deed Agreement Between Miami Dade Aviation Department and the Federal Aviation Administration for the Opa Locka Executive Airport, Opa Locka, FL
Document Number: 2021-22637
Type: Notice
Date: 2021-10-18
Agency: Federal Aviation Administration, Department of Transportation
The FAA hereby provides notice of intent to release 20.327 acres at the Opa Locka Executive Airport, Opa Locka, FL from the conditions, reservations, and restrictions as contained in a Quitclaim Deed agreement between the FAA and the Miami Dade Aviation Department, dated November 16, 1961. The subject property is located at the southwest corner of NW 37 Avenue and NW 151 Street and on the east side of the airport. The parcel is currently designated as aeronautical property. The property will be released of its federal obligations given the land is no longer required by the Miami Dade Aviation Department as aeronautical-use. There would be a positive fiscal impact to the County as the conversion of the use of this acreage from aeronautical use to non-aeronautical use will yield more revenue to the County. As such, Foundry Meek IV LLC would pay a non-aeronautical use land rent rate of $0.86 per square foot, yielding approximately an additional $555,677 for a total of $838,390 in annual rent to the County, a 4X increase in revenue over the aeronautical rent.
