They can tack on fees for specific purposes to the property tax. I haven't looked into the specific procedure the county & city uses to add them. For example here we used to pay for sewer maintenance as part of the water bill. Then they decided to move sewer taxes to be part of the property tax and so it became. (Cynically, they did it to raise water rates without attracting too much attention. The sewer fee was moved to property taxes but the water rates rose so that the water bill was about the same even though sewer was no longer in the monthly bill.)
