Why is there a stormwater fee instead of a tax?

A property's value does not affect runoff, so property taxes are not the most equitable way to pay for stormwater services. For example, a high-rise building and a shopping mall may have similar value and pay similar property taxes. However, the shopping mall produces more runoff because of the amount of parking and rooftops. The fee system ensures the shopping center pays a higher stormwater fee than the high rise.
