Before anyone gets all worked up, these "powers" are already present at the State and County levels.

FS 252.38(3)(5) - EMERGENCY MANAGEMENT POWERS; POLITICAL SUBDIVISIONS.--

--snipped--

5. To request state assistance or invoke emergency-related mutual-aid assistance by declaring a state of local emergency in the event of an emergency affecting only one political subdivision. The duration of each state of emergency declared locally is limited to 7 days; it may be extended, as necessary, in 7-day increments. Further, the political subdivision has the power and authority to waive the procedures and formalities otherwise required of the political subdivision by law pertaining to:

a. Performance of public work and taking whatever prudent action is necessary to ensure the health, safety, and welfare of the community.

-- snipped --
g. Acquisition and distribution, with or without compensation, of supplies, materials, and facilities.

It's already in the law, and it has been since at least the year 2000, but I think this has been on the books since the 1960's.
