Mansion area becoming a public pool and larger recreational park where more crime and seedy shit can happen would be tight. Maybe a cozy waterfront end, a parking lot that leads to tunnels, and a public pool and other entrance where the regular entryway to the mansion is. Just food for thought. Good place for deals, mugging, hiding out, whacking fools. Maybe a wooded thicket with diggable areas to hide and bury bodies. Etc. Just like a proper “seedy park with recreations” area instead of a big sexy eyesore nobody can utilize without being rich/connected.
