Th longtime councilman was first elected in November 2001; he was re-elected twice and began serving his most recent four-year term in January 2010.
Mayor Liz Reynolds stated by phone, "The council has lost one heck of a council member and the community has lost one heck of a council member. He had a high level of integrity."
Reynolds said as mayor and on the council, "I was fortunate to serve seven years with Kevin."
"Kevin took his job seriously," Reynolds said. "He always did what was good for the whole and set aside his personal feelings. I am really going to miss him."
The mayor said Mahelona made the Oct. 17 budget workshop, but had to skip the Oct. 24 workshop.
Reynolds said he wrote in an email, "(I) can't seem to kick this cold."
He emailed the mayor early in November and stated he thought he would miss all the meetings during the month.
Reynolds said among his many skills and talents on the council was his ability to comprehend, "every page of the budget."
