(AP) — A coalition of 27 neighborhoods groups has united to secure a share of any increase in the city’s sales tax.

City leaders are considering adding a half-cent to the city’s current rate of 1½ cents per dollar on purchases inside the city. The total would be 7½ cents.

The coalition wants $1 million for a fund to buy and fix problem properties, $2 million for sidewalk repair and $3 million for parks.

The mayor’s staff isn’t sure whether to advance the proposal for a council vote and, if approved by the council, a November ballot measure for city voters.

State law requires that most of the money be earmarked for buildings, equipment, roads or tax relief. But 15 percent can be used for programs run jointly with another public entity.
