The map to the right shows Washtenaw County, Michigan. Ann Arbor/Ypsilanti
is the large central burgundy region. Ypsilanti lies to the east
of Ann Arbor.
The layers in this map include:
-
surface streams (thus, much of Allen's Creek--that portion in a pipe--is
not shown)
-
surface lakes
-
minor civil divisions (outlined in red)
-
impervious surface, as indicated in the legend on the map. The percent
impervious is by land use parcel as designated by Southeast Michigan Council
on Governments (www.semcog.org).
