A map of Gresham, Oregon showing street names and city limits. Section lines and section numbers are noted on the map (the area covered in the map is all within Township 1 South, Range 3 East, Willamette Meridian). Johnson Creek is shown along the southern edge of the city. Two railroad lines are shown: P.E.P.Co.R.R. (Portland Electric Power Company) runs through downtown Gresham along N.E. 10th Dr., in roughly the same spot later occupied by TriMet's Blue Line MAX light rail. O.W.P.R.R. (Oregon Water Power & Railway Company) runs along Johnson Creek; this line has since been converted to a multi-use path called the Springwater Corridor. This map appears to show Gresham at some point before the 1960s.
