City officials Monday told developers the national Olympics movement organization required a mix of apartments, townhouses and dormitory-style accommodations for married and single athletes in addition to 90,000 square feet of new downtown administrative office space, the Colorado Springs (Colo.) Gazette reported Tuesday.

Two of four local real-estate firms have submitted proposals to provide new USOC facilities in town in a bid to keep the organizing committee from moving its headquarters, with 240 employees, and Olympic Training Center away.

The USOC moved to Colorado Springs from New York City in 1978.
