A focused companion to the 1852 Portland Map (which includes the entire city area) comes from the early Portland 1852 Survey, encompassing the downtown area adjacent to the Willamette River. One interesting pattern is the street grid running right into the waterfront – as the river was the hub of commerce. As the city evolved this interface with the river lefts some interesting patterns.
Again, a couple of early creek corridors are shown on the south portion of downtown, originating at SW Jefferson Street and winding down SW Columbia to 3rd. There’s another stream originating from Mill Street and continuing southward.
And the form that continues through of the park blocks, in this form continuing from SW Clay to SW Stark. This is a pattern of park blocks that continues north and south as shown in the 1866 Map. I’m curious where in the development pattern the North and South Park blocks were severed.
