Here is the first of several fact sheets concerning the City of Oakland’s plan to cut down a large grove of redwoods, oaks, and other native trees and bulldoze the banks of Sausal Creek. Several other fact sheets, including #1, are in progress.
Larger images of the maps pictured here will be uploaded soon, together with info on how to obtain them directly from the U.S. Geological Survey website.
Downloadable 11 X 17 posters are available at: https://docs.google.com/open?id=0B5Sup347J8OnREpMQi1wU182d0U
Depending on your printer setup, within your PDF printing screen you may need to adjust the “tile scale” to somewhere in the 90-97 range; this enables printing it out on one sheet of 11 X 17 or two sheets of regular 8.5 X 11 paper.
Larger map images will be posted asap.

To locate these and other maps yourself, go to http://nationalmap.gov/historical/ and follow the links to your preferred search and download method. If you use the map-based method, click on the current Oakland East quadrangle for a listing of all historic maps available; you will then have the option of downloading these and other years’ maps for the area.
Note: In 1915 these maps covered 15 X 15 minutes of the Earth’s surface, as the country was less settled; so you are looking for the 1915 Concord Quadrangle. By 1959 the USGS was using 7.5 X 7.5 minute maps, hence they are then known by the Oakland East designation.

Thank you everyone for your patience with the slow rollout of this blog, and for your continued support of the trees — they could already have been cut down otherwise.
