Orlando County taxes are due March 31, so not quite a full year to figure something out.
Assuming nothing changes, since everyone who will be responsible if nothing changes has to assume that's what is going to happen.
How long does it take to implement changing services? Just the mechanics of making the change. Say the fire department. Assuming no people or any infrastructure are changed, only the controlling entity. At a minimum payroll and benefits need to be transitioned from RCID to some new entity. Just implementing that change takes time.
How long does it take to plan that implementation? How to figure out how to onboard all the people, how to "fire" them from the prior entity, any differences in benefits and pay. How many are going to stay, how many go, will there still be enough to run the services.
Take those two times, but make them much larger since it will also require a full inventory of services transitioning and determining what to keep, what overlaps, and how to merge them in.
Now, subtract all that time from the dissolution date that is the current law. That's your new drop dead date to have some other hypothetical solution that doesn't need all those things done.
Having been involved in corporate mergers more than once, I can tell you those issues are substantial even when everyone wants the same thing.
There's nowhere near a year from now until the impacts start.
Bonus, if they assume it's not happening and then it does, it'll be a total catastrophe. The kind where people don't get paid, services fail, and people are hurt.
