WICHITA, Kan. (AP) — Two Koch family foundations are making a $10.5 million donation in land and money to the new Wichita Center for the Arts.

A new 38,000-square-foot center is planned for 17 acres owned by the Kochs. The project, without the land, is valued at $14 million.

The Wichita Eagle reports the Charles Koch Foundation is donating the land, which is valued at $4.5 million. The Fred and Mary Koch Foundation is giving $2 million and will have another $4 million challenge grant.

Liz Koch, an honorary trustee for the arts center, says the donation honors her mother-in-law, Mary Koch, a strong supporter of the arts center who died in 1990.

Construction is expected to begin in late 2016 and be finished by late 2017 or early 2018.
