Archaeological monitoring was conducted by PanGIS, Inc. for installation of 575ft of gas main beneath the Georgia Street Bridge in the North Park neighborhood of San Diego, California. The purpose of monitoring was to assist San Diego Gas and Electric (SDG&E) in its compliance with the California Environmental Quality Act (CEQA), which included supervision of the removal of approximately 20ft of historical trolley tracks.

Research was also conducted regarding the trolley tracks, primarily consulting Richard Dodge’s Rails of the Silver Gate: The Spreckels San Diego Empire (Golden West Books, San Marino, CA: 1960).  The removed rail and a sample of associated hardware, brick, and redwood tie were delivered to the San Diego Electric Railway Association in National City (President Mike Reading) for use in an interpretive display.
