Well, they would do that by buying the land from the city! Could mandate a home owners association like thing as an extra tax like levy to maintain the canal and retaining walls long term.Sorry, I meant the restore facades project . That said, maybe the creosote cleanup/canal village project could be a corporate sponsorship thing, for at least part of the cleanup. Developers who get parcels of land right on the water could pay for part also. Just a couple of ideas to throw out there.
