The prop would reportedly generate $250 million for the city over a five-year period.
The city will allocate 40 percent of the funds towards preserving and reconstructing streets.
The other 60 percent will be divided between Tucson's Police and Fire Department.
Barrett Baker with TFD says this money will have a huge impact on their fleet.
"90 percent of our medic fleet is over that reliability threshold and that's either 10 years or 100 thousand miles and once we get past that certain thing, now the repairs become more often, more frequently, more expensive," Baker said.
He says TFD received about 92,000 calls last year and that number isn't going down.
"It's so important that 100 percent of the time that the person is having an emergency that we can get to them reliably and safely, quickly and that means the fleet has to be up-to-date and new and this would definitely take a step in the right direction to get us there," he explained.
The city estimates residents will pay about $3 per month for five years if the prop passes.
