Newton voters will decide March 12 whether to pass the city’s first property tax override in a decade to pay for aging buildings, deteriorating sidewalks, and rising student enroll­ment.

The Board of Aldermen voted unanimously Monday night to ask voters for an $11.4 million override of Proposition 2½, approving Mayor Setti Warren’s proposal to raise additional tax revenue for the city. “We feel very strongly this is the right package to invest in the future,” Warren said Monday night after he personally thanked each alderman.
