Cisco sits at the intersection of US Highway 183 and Interstate 20 in northwestern Eastland County, at an elevation of about 1,644 feet. The terrain here is part of the West Cross Timbers region, with hilly, rolling ground ranging from 1,200 to 1,800 feet and soils that vary from sandy to loamy across the county. That sandy-to-loamy soil variation matters for concrete work: sandy soils drain quickly but offer less bearing capacity, while loamy patches hold moisture longer and can shift with wet-dry cycles. Lake Cisco, just north of town, draws property owners who want acreage with recreational access, and the I-20 corridor makes this a practical location for both residential and small commercial metal building projects.
