Voters will decide on April 2 whether to extend the half-cent sales tax for another 10 years. Revenues from the tax have been used to pay for major transportation projects and to stabilize the city's property tax levies.

The following information, provided by the city of Garden City, shows the impact on the mill levy and annual property taxes if the sales tax is not reauthorized. The city also provided a list of past and future projects that used or would use sales tax revenue.

Impact of 17 mills on a $150,000 home:

* $17,250 in assessed valuation

* 2013 mill levy: 38.963 mills

* Current city tax is $672.11

Without the sales tax

* 2013 mill levy plus 17 mills = 55.963 mill levy

* City tax would be $965.36

Total current city taxes collected: $13,483,755

* Sales tax: $9,426,217 (69.9 percent)

* Property tax: $3,602,341 (26.72 percent)
