After more than 35 years with Collier County, George Yilmaz, public utilities director, left to take a job as Naples’ critical infrastructure director. Yilmaz, who celebrated 35 years with the county in December, will oversee the city’s Streets & Traffic, Stormwater, Natural Resources and Engineering divisions. He began April 7, with a salary of $187,890. The city’s Public Works Director Bob Middleton had planned to retire this summer but has agreed to extend his tenure at least through this year, said city Communications Manager Monique Barnhart. She added that Middleton will continue as public works director, overseeing the utilities divisions, as well as Yilmaz’s position. Middleton’s current salary is $206,165. He was hired by the city in November 1992 as its public utilities operations superintendent, became director in 1998 and acting public works director in 2008 and was named public works director a year later.
