Janesville dominates the western portion of this 2022 survey, showing the continued expansion of its residential and commercial corridors east toward the rolling agricultural lands of Rock County. The city's growth is framed by major transport arteries like Milton Ave and Humes Rd, which transition from urban grid to open country. In the east, the settlement of Emerald Grove remains a distinct anchor, positioned near the Emerald Grove Cem and Hacklander Airport.
