A spacious new City Hall is rising not far from the river canyon that gave Post Falls its name. But attention is not on the construction work; instead, it's on the masonry block old City Hall next door – a building city officials had planned to demolish next year. Some residents want to save the old building for public use, such as a museum. Others say that would cost too much. The debate has divided the fast-growing city of more than 25,000, and voters will decide in the Nov. 6 city election if the building stays or goes. Preserving the 7,500-square-foot structure at this late date would cause a financial crisis, said City Administrator Eric Keck. Taxpayers would have to foot the estimated $1.2 million bill, plus pay $60,000 a year in operating costs. And they'd get an aging building fraught with maintenance problems, Keck said.
