City officials are working to contact more than 1,600 voters who did not receive a ballot.
The city has mailed postcards to each individual that they will receive by Tuesday.
A special election is being held Tuesday to vote on Prop 101. A temporary half-cent sales tax increase will fund improvements for roads and public safety. If approved, it will cost taxpayers three dollars a month.
There are other options if you don't receive your ballot. You can pick up a replacement ballot at the Tucson City Clerk Elections Center every day except Sunday.
