A city's public spaces are its primary assets. No third party should be given the power to close off areas that have been held in common since New Haven was incorporated. This sale would be a mistake on any terms, a grievous one on the terms offered.
Permanently abandoning public spaces to a private entity is not in the city's interest. Their future value cannot be realistically assessed. As they are part of the commons, the public should be directly consulted via referendum before they are sold to a third party.
