Slammed Treasure Island -
It was an art deco masterpiece—a "fairy city" of white towers and neon lights. But as soon as the fair ended, the treasure chest slammed shut. The Navy took over the island, using it as a naval station for 50 years.
The current $5 billion redevelopment plan calls for raising the entire island by 3 to 7 feet using compacted fill. Critics have slammed the plan as a "leaky band-aid." Sea-level rise experts argue that by the time the last condo is sold in 2035, the data will already be outdated.

For decades, the island sat in limbo—affordable housing for the working class, but a poisoned chalice for developers.
