YOUNGSVILLE — The city of Youngsville is on track to get a major upgrade with a 70-acre sports complex that will offer residents a place to play an array of sports.

Rick Garner, Youngsville’s chief executive officer, said construction on the Youngsville Sports Complex could begin as soon as this week, but a groundbreaking ceremony has been postponed until Tuesday.

“This is going to be a jewel of south Louisiana,” Garner said. “It’s going to be a shot in the arm economically for Youngsville.”

The approximately $20 million project is split into two phases and is being funded with a 1 percent sales tax that Youngsville voters approved in November 2011.

The project’s first phase, which will be completed in December, includes 10 tennis courts; six soccer fields; five baseball fields with artificial turf on the infields; four softball fields; two two-story concession stands, one for the baseball fields and one for the tennis courts, with covered 360-degree observation decks on the second floors; a 1-mile jogging track; a fishing pond; parking lots; a playground; and other amenities.

The project’s second phase, which is under design this year and will be under construction in 2014, includes a community center with offices for staff members overseeing the sports complex and two basketball courts.

Dax Douet, the project engineer who works for C.H. Fenstermaker and Associates, said the project’s first phase will cost about $15.2 million, and the second phase will cost about $5 million.

The sales tax dedicated to the complex passed 56 to 44 percent, with 811 Youngsville residents voting in favor of it.

Youngsville Mayor Wilson Viator said the tax has brought in about $140,000 each month since being implemented in April.
