James Vacca and the City Council Transportation Committee continue to tackle the pressing issues facing our streets and transit system. Among the legislation getting a hearing at this week’s transpo committee meeting is a bill from Brooklyn Council Member David Greenfield that would ban city agencies from placing adhesive stickers on motor vehicles. The Department of Sanitation uses stickers to shame alt-side parking violators who block the path of street sweepers. The likely outcome if Greenfield’s bill passes: dirtier streets and sidewalks.
