For anyone wondering (like I was) what the National Park Service has to do with this:
According to Dasher Hurst, the proposed restoration is waiting for final approval from the National Park Service, which regulates historic preservation projects in federally designated historic districts, including Downtown Jacksonville.
There's no reason for Curry to not sign, right?
The National Park Service under the Dept of the Interior is the federal agency in charge of the National Register of Historic Places. NPS has to approve the proposed renovations and building alterations in order for a redevelopment/rehabilitation to qualify for federal historic rehabilitation tax credits.
This is true for any project seeking tax credits where the building is either protected under the National Register of Historic Places, or for any buildings/complexes identified as contributing structures within a registered historic district. The Independent Life, Ambassador Hotel and Marine National Bank buildings are all contributing structures within the Northbank's National Register Historic District
As for the Mayor's signature- it isn't required as the Council has passed the bill by a super-majority. He could sign it, or choose not to sign it.
