Johns Creek closed on the 133-acre Cauley Creek property that includes a water reclamation facility Fulton County declined to buy.
The city will "consider all options regarding the future of the" Cauley Creek Water Reclamation Plant, a statement said. The plant will be maintained for one year, but is not currently in use.
Johns Creek bought the property as park land for $20.3 million.
“By acquiring this property, we are addressing our residents’ desire to add recreational opportunities for the Johns Creek community,” Mayor Mike Bodker said in a statement.
The purchase was completed earlier this month. The plan for the park will begin later this year.
Late last year, Bodker tried to convince Fulton commissioners to buy the water treatment plant. The county declined, saying it would cost an additional $54.3 million over 20 years and that it wasn't needed to meet Fulton's sewage needs.
