The neighborhood is bounded by the Mississippi River to the north and the city limits to the south.
[1] The West Side Flats were located adjacent to the Mississippi River near downtown.
[2] The area was replaced with an industrial park that was eventually protected with a flood wall.
The border is most a straight line with an exception of a 40 acre notch that is located in West St. Paul.
The irregular border was created in 1874 so that a well connected resident of the notch could remain in Dakota County.
