Providence could face bankruptcy in June, Mayor Angel Taveras warned yesterday. In a press conference, the mayor urged tax exempt non-profits to pay their fair share to the city to avoid fiscal collapse. He also called on city retirees to suspend cost of living increases in their pensions, which compound five to six percent yearly. Providence faces a budget deficit of 22.5 million dollars this fiscal year. Renewed payment negotiations are underway between Brown University and the city government, and the city will hold a town hall meeting to discuss pension cuts with retirees March 3rd.
