General Development Corporation
General Development Corporation, also known as GDC, was the largest land development company in Florida. Founded in 1954 by brothers Elliot, Robert, and Frank Mackle Jr., and based in Miami, Florida, GDC established several "NEW" communities in the 1950s & 1960s, and promoted inexpensive Florida homesites worldwide.
Communities developed by Mackle Bros. and GDC
- Port LaBelle, Florida
- Port Charlotte, Florida
- North Port, Florida
- Port St. John, Florida
- Port Malabar, now a subdivision in Palm Bay, Florida
- Port St. Lucie, Florida
- Sebastian Highlands, Florida
- Deltona, Florida
- Key Biscayne, Florida
As each community started the developer built the roads, sewer and water plants, golf courses, marinas, other basic amenities and even operated landfills. These new communities had the feel of "company towns." When North Port was incorporated GDC employees even made up the first City Council.
In the 1960s GDC's board of directors hired Charles H. Kellstadt, retired Chairman of Sears as President and Chairman. This was just after the GDC board voted to split with the founding Mackle Brothers. The Mackles went on to develop Marco Island and other prominent communities.
Kelstadt, it was said, implemented a money back guarantee on homes and lots, similar to what Sears offered. This was a powerful sales tool, and combined with the ability to swap remote lots for lots in the developed areas, this allowed GDC to achieve tremendous sales success, selling several thousand lots each month and several hundred homes.
Then, in the mid 1980s City Investing took the company public again.
In the late 1980s GDC's management team was accused of fraudulent home sales: this led to criminal indictments of the company leadership, and bankruptcy of GDC in 1991. Functional assets held by GDC in various cities were turned over to their respective governments thereafter.
Subsequent to the indictments and convictions of senior management, the 11th Circuit Court of Appeals exonerated the men, reversing their convictions and directing that all charges against them be dismissed (see US v. Brown, 79 F.3rd 1550 (1996), for a complete discussion of the case and a general exoneration of General Development Corporation.
The company had a court-appointed CEO, Thomas J. Hutchison III, from 1990 to 1991.
