A heavy equipment company has received approval from Miami-Dade County commissioners to relocate its headquarters to a site outside the county’s Urban Development Boundary (UDB), paving over more than 160 acres of wetlands in the process.
The decision, made despite opposition from county planning staff and environmental advocates, allows Kelly Tractor to move its base of operations near Sweetwater. The company plans to build on land it owns outside the UDB, developing facilities for selling, storing, and repairing machinery. The newly approved project area will be labeled as the “MIA Transportation and Infrastructure Support Area.” Several conditions were attached to the approval, including requirements for wetland mitigation and further review through an administrative site plan application.
County planners had recommended denying Kelly Tractor’s proposal. Their report noted that there are about 700 acres available for industrial development within the existing boundary and questioned why expansion at the company’s current Doral location was not possible. They also raised concerns that taxpayers would bear costs for water, sewer, and other infrastructure expansions related to the new facility. Planners highlighted that Kelly Tractor did not provide a mitigation plan for wetlands considered among the most valuable in Miami-Dade.
Kelly Tractor argued that relocating is necessary to support major infrastructure projects such as highways and prisons. At the commission meeting, a company attorney stated that Kelly Tractor has outgrown its current site and no adequate parcels exist within the UDB for their needs.
Environmental groups have expressed concern about building on wetlands vital for flood control in Miami-Dade. Laura Reynolds, science director at Hold the Line Coalition, told WLRN: “Wetlands are very functional. They’re part of the solution for flooding for [Miami-Dade County]. Sweetwater floods all the time and these are the things that should be considered when we make these decisions.”
Development proposals outside Miami-Dade’s UDB have often sparked controversy. In 2022, developers Stephen Blumenthal and Jose Hevia gained commission approval after multiple attempts for their South Dade Logistics & Technology District on 379 acres beyond the boundary; however, this project was later overturned by a court in 2024.
Another significant proposal expected to come before commissioners later this year is City Park—a planned community with 7,800 homes and 2.4 million square feet of commercial space outside the UDB. Developers Lennar, Ed Easton, and Bill Albers back this initiative. Supporters claim it will be self-contained with schools and parks included; critics argue it could worsen traffic congestion into key employment areas.
While Miami-Dade has long been seen as friendly to developers, officials have typically drawn firm lines against expanding urban development onto open land near protected areas such as Everglades National Park or Biscayne National Park.
