In its third and final vote, Metro council members approved the controversial incentive plan for Opryland's proposed $90 million "Soundwaves" indoor/outdoor water park.

Metro Council voted on the plan Tuesday evening. It was approved 30-6. The estimated $13.8 million incentive package will freeze Opryland's property tax payments through 2025.

“The real interest for the city is attracting additional tourists who help fuel the economy in Nashville," Matt Wiltshire, director of Economic and Community Development in the Mayor's Office, said. "By bringing in tourist dollars and by supporting jobs for Nashvillians, this park will help keep taxes for Nashville residents even lower."

As part of the deal, Metro Parks will get new property on the Cumberland River with boat ramp access.

However, a number of Nashville residents have voiced opposition to the plan – mainly because only resort guests will be able to use the park.

In the second reading, only three Metro Council members voted against the tax incentive. If that vote is mirrored on Tuesday, the tax incentive plan will pass.
