Now in its sixth year, the sprawling Katy Ranch Crossing development is undergoing its fourth and final construction phase.

The mixed-use development is located approximately 1 mile southwest of the intersection of I-10 and the Grand Parkway. It encompasses retail and office space, and a 318-unit luxury apartment complex.

Owned by Freeway Properties, Katy Ranch Crossing was built on former cattle fields in four phases beginning in 2011, according to property manager Ed Friedman. The first Phase 4 tenants are expected to open in November or early December, he said.

A concrete shell building is under construction at the corner of Katy Fort Bend Road and Market Place Drive, where Friedman said about five different businesses will open. The shell building is on the west side of a 15,000-square-foot strip center.

Friedman said June 26 three tenants were expected for the strip center but did not release the names, because the leases were not signed.

In addition, Friedman said two 8,000-square-foot buildings will be constructed in front of the shell building along the I-10 frontage road. Once complete, Katy Ranch Crossing will include roughly 1 million square feet of retail space, he said.
