Mayor John Anataramian and the city’s police and fire chiefs are calling for voter support of a referendum on the Nov. 6 ballot that would allow for the hiring of additional police officers and firefighters next year. They said more public safety personnel are needed partly because economic development and population expansions have grown the city to the point where the departments are currently overtaxed. Officials said the city has grown to more than 100,000 residents. A referendum is needed because current state laws limit the city’s ability to raise the necessary funds through taxes, officials said. “Current formulas used by the state severely limit our ability to hire officers and paramedics,” Police Chief Daniel Miskinis said.
