Lee has already put his stamp on 2012 - it has a serious face

Sunday, January 1, 2012
If 2011 was the year of the quirky and unexpected at City Hall, 2012 promises to be serious and meaty. That was bound to be the case with the election of Mayor Ed Lee, the longtime bureaucrat who is driven around in a four-door Ford Fusion sedan and has demanded that his Jan. 8 inauguration feature nothing splashier than kids' choral groups. His first major move of the new year will be naming the replacement for District Five supervisor now that Ross Mirkarimi has been elected sheriff. Another major appointment for Lee will come when Public Utilities Commission General Manager Ed Harrington retires, likely this summer.
