No other significant named new construction projects (multi-unit residential, condo, hotel, or mixed-use) meeting the criteria were identified on Siesta Key. The island is largely built out with strict zoning and coastal regulations, limiting activity primarily to individual custom single-family home teardowns/rebuilds (many luxury Gulf- or waterfront estates listed as new construction on real estate sites) and public infrastructure upgrades. Mainland projects like Siesta Promenade (at the US-41/Stickney Point gateway) are not located on Siesta Key.
