text_A: Olmsted County is a mix of urban and rural areas but the transitions and buffers between the two environments are unusual in that they are very long. Rochester, Minnesota’s third largest city of roughly 118,000 people sits in the Zumbro River valley at the center of the county. Outside the valley however, with the exception of a small amount of urban growth in the last few years, remains farmland with small agricultural based communities and no directly adjacent suburbs. Stewartville, the county’s second largest city, is slightly over 1/20th the size at roughly 6,000 people, an unusually large gap for a metropolitan area.
text_B: Would you be likely to find a densely packed area with large buildings very close to farmland in Olmsted County?
NO.
