Gainesville City Council will approve an agreement today with an Atlanta engineering consultant to develop a comprehensive stormwater management program, which includes implementing a “rain tax” to pay for upgrades and replacements to aging drainage infrastructure. The $208,000 contract with CH2M Hill Engineers calls for a public education program, identifying actual costs, creating a billing database and consulting on mapping and analysis. Kelly Randall, director of the Department of Water Resources, has said the proposed tax or fee would not likely be implemented prior to 2017.
