incentives for cities and counties to stop providing free parking on the street and at government offices
Sounds like trying to eliminate it to me. The reduction would be on the employers side like you said. People who park in employers parking would now have to pay for their own or their employer will have to pay for it.
If you think the taxes in the areas will go down you have to be delusional. The taxes will stay the same or increase.
