Holley, who oversaw the Parks and Recreation division, earned $64,563 and will not be receiving severance pay since this was a voluntary resignation, according to Deputy Director of Public Affairs Holly Lafontaine.
A hiring freeze was instituted in June but department heads can come to the Commission Chairman Richard Oden with special hiring requests, said Lafontaine.
Recreation and Maintenance Director David Smith might look at reevaluating the department.
"Now that someone in management is leaving, he wants to make the best decision," she said.
As of July there were 44 vacancies among 515 positions under the jurisdiction of the Chairman in the 2009 budget.
