Just demolish the pool. Keep the facade and canon. Don't use any more concrete, steel, or rebars as they don't last forever. Build a magic island exactly like the Alamoana one. It was beautifully built and is still as new as the day it was built. Boulders, dirt, and sand are Nature's building blocks and it's free. Having a park would be excellent for private weddings, volleyball contests, exercising classes, suntanning, or floating around in the lagoon-like pool. Might add a Zippy's to help pay for maintenance costs or charge users, too. One thing you'll need to figure out is how to make more parking spaces for the increased users. Try widening Kalakaua Ave and make diagonal parking then jack up the meter fees to limit the traffic to more manageable levels. This Natatorium has been is disrepair way too long. Do something with it!
