The fate of a proposed 1-cent sales tax to fund improvements to the Lafayette Regional Airport will be in the hand of voters Dec. 6.

City-Parish President Joey Durel and other city leaders have said the tax would only be collected for eight months during 2015, and revenue generated from that tax could only be used for the one purpose.

In an interview with the Daily Advertiser, Tyron Picard, a consultant handling governmental affairs for the airport, said the tax could be struck down if voters are apathetic or don't understand the tax.

The tax is expected to generate about $37 million toward the $90 million project, which includes a new airport terminal, up to 50 percent more parking and related infrastructure.

Lafayette Regional Airport has only three boarding gates and, under the current configuration, no room to expand.

Durel pitched the general outlines of the proposal during his annual State of the Parish address earlier this year.
