Knoxville serves as the focal point for this 2018 survey, showcasing the street grid of the county seat as it expands toward the Knoxville Municipal Airport and along arterial routes like W Bell Ave. The landscape is defined by the branching tributaries of English Cr and White Breast Creek, which carve through the Iowa terrain toward the southern reaches of Lake Red Rock.
