The Airport Commission approved a new airport manager job description Tuesday at its regular monthly meeting and Chairman Jeff Naughton announced that Greenwald would be leaving his post July 1. We have to have to find someone to replace Bill; he has done a wonderful job, Naughton said. Naughton did not go into the reasons for the resignation but after being asked about further resignations during public comment, he affirmed that he too would be leaving July 1 along with fellow Commissioner Armand Boillat. He said he did meet with Mayor Thomas Bernard and there are no plans to reduce the five-member commission. He said the mayor must appoint two new members.
