The University of Kansas hopes to have a new sports complex ready for use in time for the Kansas Relays in 2014.

Lawrence city commissioners on Tuesday approved rezoning requests and a special use permit that will allow the university and its private partners to move ahead with plans for what will be called Rock Chalk Park. It would include a track and field stadium, soccer field, softball stadium and other amenities on about 90 acres.

The Lawrence Journal-World reports the commission's vote does not commit the city to build a $25 million recreation center in the park. Commissioners won't vote on that part of the project until mid-February.

Jim Marchiony, associate athletic director at the Kansas, says the university hopes construction could begin in February or March.
