According to early voting results, 83.55 percent of Georgetown voters are in favor of continuing the city's street maintenance sales tax.

Proposition 1 applies a quarter-cent sales tax to purchases made in stores within Georgetown to fund street maintenance. The tax does not affect the sales tax rate or property taxes.

The ballot item has received 10,791 votes in favor and 2,124 votes against.

Voters approved this measure for the first time in 2002, and it must be reauthorized every four years. The proposition received approval in 2006 and 2010.

Since going into effect the quarter-cent sales tax has generated $20 million, and in fiscal year 2014–15 it is expected to generate about $2.05 million, according to Chief Financial Officer Micki Rundell.

If approved, the collected revenue applies only to projects completed between this election and the previous approval in 2010, and the money may not be spent on building new roads—only maintaining roads.

There are 610 lane miles of streets in the city. Georgetown's street network has grown by 275 percent in the past 20 years, and since 1994 Georgetown has added nearly 400 lane miles, according to Mark Miller, transportation services manager for the city.
