On Friday, New London Mayor Michael Passero walked away with a pretty good deal for his city. But, I suspect, the mayor realized that if he pushed his luck much further, he could have walked away empty handed. For the past year, Passero had sought assurances that New London would see a fair and reliable revenue stream to city coffers as a result of the massive development that is intended to turn State Pier from an underutilized port into a busy hub for the assembly of wind-power turbine parts and their transport to offshore wind farms. The mayor's aspirations were complicated by the fact State Pier is state property, and so not subject to property taxation. And under the public-private partnership negotiated with the developers, the heavy-lift cranes and other infrastructure to be constructed will also be untaxable state property.
