As part of a compromise with the county, city officials agreed to stop collecting 0.067 percent of its sales tax to make it available for the county to begin collecting July 1. That is the total tax county voters are being asked to consider Tuesday.

Should the tax be approved by voters, the sales-tax rate would remain the same in the city of Tulsa and increase by 0.067 percent in other Tulsa County municipalities.

The campaign to promote the sales-tax proposals has been low-key and low-budget.

Keith and Glanz, along with other county officials, have taken every opportunity they could to speak to civic groups and other organizations about the proposal.

They also created the Protect Our County public awareness campaign that included mailers. The campaign is funded by Citizens for Tulsa County, an account established by the Tulsa Regional Chamber to fund issues campaigns.

As of March 17, Citizens for Tulsa County had raised $84,000 for the Protect Our County campaign.

Opposition to the sales-tax initiatives has come primarily from Citizens for a Better Vision. The group was established to oppose the Vision2 proposal that failed in 2012.
