The Franklin Board of Mayor and Alderman voted to give to build new schools money from a potential half-percent sales tax increase Tuesday night.

County Mayor Rogers Anderson proposed the idea to the board earlier this month as a way to raise revenue for schools.

“We’ve got to create revenue where we can,” Anderson said.

The Williamson County School District projects it needs more than $500 million over the next two years for new school construction.

Franklin voted to give up its portion– about $21 million over three years– of the sales tax. After three years, the revenue will divert back to the city.

“Ultimately, however, it is up to voters,” Anderson said.

The county will set up a special referendum in the fall to give voters a choice to increase the total sales tax in the county from 9.25 to 9.75 percent.

The county is currently in the process of asking all the municipalities to give up a similar percentage of their sales tax for the same purpose.

The mayor presented to Spring Hill’s BOMA last week and they will vote on Monday. Nolensville last week was the first to vote for the sales tax, and it went the way of Franklin.

Nolensville will give about $300,000 extra total under the deal they voted on.
