McKinney is the county seat for Collin County, the fastest growing and most affluent county in Texas. The city’s motto is “Unique by Nature,” exemplifying the rolling hills and tree-filled terrain that complement a community offering golfing, hiking, biking and a variety of sporting venues and settings. Homes surround the community’s numerous lakes and golf courses. Lush greenbelts following winding creeks are the setting for much of McKinney’s residential new construction. McKinney’s historic downtown square has the finest in dining, shopping and the arts -- and the residential area surrounding the square dates back to the 1840’s with some of the state’s greatest treasures.
