Here is a new map for understanding the historical path that Sunnyside’s tributary of Islais Creek once took through the neighborhood, a composite using color Sanborn maps from the Library of Congress and DavidRumsey.org from the early 1900s. Additional information for areas not covered by Sanborn from Joel Pomerantz’s Seep City project for mapping our city’s old waterways.

A culvert was installed from one side of Monterey to the other at about Edna Street in the 1910s. Part of the creek was contained in a box drain in the 100 block of Flood Ave (north side) about the same time. Other manipulations took place, until the City diverted the water that would have fed it into the sewer system, during the 1920s.
