(Portland, OR)  --  The city of Portland is asking the federal government for about three-point-two-million dollars in disaster aid to help cover costs of responding to January's snow and ice storms.  City officials tell "The Oregonian" one of the largest costs was the estimated one-point-six-million dollars needed to remove snow and ice from city streets.  It cost more than a half-million to remove debris and repair traffic signs and markings, and another half-million to repair water-main breaks.
