The city I live in has an entire list of projects by quantity of outside funding that would be required for them to go ahead. Generally they look to local, provincial, and federal levels each provide 1/3 for major infrastructure projects, including major roads, transit, and so on.
In the case of a starbase or berth, it's likely that the local government or fleet has a project on the books but would not approve the project unless it received a fair proportion of outside funding. That's not to say that it would be paid for entirely by Council-level funds, but 1/3 agency, 1/3 member, 1/3 Council is not out of the question? Or even 1/2 member 1/2 Council? But these projects would not even make it past the drawing board without a funding agreement from the federal level.
