The Chennault International Airport Authority is looking at a $257 million expansion to increase the airport’s cargo-handling capacity.

The proposal includes building on 220 acres already occupied by Mallard Cove Golf Course.

Randy Robb, the airport’s executive director, tells the American Press (http://bit.ly/1CJpQib ) the expansion could result in up to 1,500 permanent jobs.

Robb says Mallard Cove causes hazards for airport operations, including wildlife, along with birds and golf balls hitting aircraft.

He says Chennault would provide an alternative golf course.

The city of Lake Charles developed Mallard Cove in 1976 on land that was donated by the federal government.

Robb says would take about 18 months to develop the new golf course. He says the plan is for Mallard Cove to remain open until a new course is opened.
