Collin County (C-18/19), is located in northeastern Texas thirty miles south of the Red River. McKinney, the county seat, is thirty-four miles northeast of Dallas. The county's center lies at approximately 33°11' north latitude and 96°34' west longitude. With the exception of a small portion of its western edge, Collin County's area of 851 square miles lies entirely within the Blackland Prairie region of Texas. The surface of the county is generally level to gently rolling, with an elevation ranging from 450 to 700 feet above sea level. Deep clayey soils over marl and chalk surface the central and western part of the county. Dark loamy alluvial soils, subject to flooding during the rainy season, lie in the eastern section. The western and central portions of the county are drained by the East fork of the Trinity River. The Elm fork of the Trinity drains the eastern section. Bois d' arc, oak, elm, ash, pecan, and post oak trees grow along the streams of the county but not in sufficient quantity for commercial use. Limestone and sand for making cement are the only mineral resources. Temperatures range from an average high of 96° F in July to an average low of 34° in January. Rainfall averages just under thirty-five inches a year, and the growing season extends for 237 days.
