Peachtree City tourism officials are proposing a significant change to the city’s annual summer concert series for next year.

The proposal comes as the city’s amphitheater is projected to end this year in the red by over $236,000. The 2009 concert series would still consist of 10 acts, but with one-night shows only instead of the current slate of two shows for each artist.

There is no proposed ticket price increase for either series or individual tickets, according to a memo to the City Council from the city’s Tourism Association.

Council is expected to vote on the new tourism budget at its meeting Thursday night.

Despite the projected $236,000 loss at the amphitheater, the association expects to end this year in the red by $82,000, thanks in part to $150,000 left over from the general fund. The tennis center is projected to have a profit of $3,700 at the end of this fiscal year.

The 2009 budget proposal includes cutting more than $521,000 for the two concert series and slashing “other program expenses” for the amphitheater by an additional $213,000.
