As the municipal home of NRR is facing a deteriorating financial position, I have a suggestion. Divest non-essential services. In particular, sell the rights to operate parking meters.
Chicago just raised $1.15 billion in cash by selling their meter rights for 75 years. They have 36,000 meters, while Minneapolis has only 6,800. But that would still result in a payment something over $200 million, assuming a similar rate.
