The L.A. City Council voted 12-0 to put the measure on November's ballot. It calls for a flat $3-a-month parcel tax, which would help fund after-school and job training programs. Council approval had been expected after Councilwoman Janice Hahn removed a last-minute provision that would have allowed the tax to be increased every year. Now comes the hard part: getting a two-thirds majority of voters willing to fork over the money. Three bucks a month isn't much to ask, but the proposal will be running next to several other tax measures. Besides, voters have been stung over the years by approving revenue-generating plans that don't end up going for what they were intended for.
