The planned $200 million development next to the regional Tri-Rail station on Yamato Road won’t be on track any time soon. Homes, shops, and office space that had been planned by developer Michael Langton are running up against disagreements with the South Florida Regional Transportation Authority and the city of Boca Raton. The project is larger than zoning regulations allow. In 2003, the city council agreed to permit up to 50,000 square feet of offices and 20,000 square feet of retail at the site west of Interstate 95 on the south side of Yamato. Langton wants to build a 150-room hotel, almost 200 moderately-priced housing units, 90,000 square feet of offices, 55,000 square feet of retail, and parking garages with more than 1,700 spaces.
