Gainesville officials are pushing forward with a plan to create a stormwater utility and implement a “rain tax” to pay for upgrades and replacements to aging drainage infrastructure. Launching the full-scale program will include renaming the public utilities department the Gainesville Department of Water Resources. It is “high time” that the city establishes a specific utility, similar to water use, to fund stormwater projects, Councilman George Wangemann said Thursday morning during a work session discussion of the proposal.
