Starting with the first horse-drawn trolleys introduced by the San Diego Streetcar Company in 1886, San Diego’s history included the growth and decline of several trolley systems. After electricity arrived, San Diego was the site of early experimentation for electric trolleys on the West Coast.  Soon after the railway expanded rapidly, leading to the development of new trolley suburbs at the turn of the century, including North Park, Normal Heights, and Mission Beach.

Douglas W. Mengers is a 20-year resident of San Diego. His passion for San Diego history was sparked when he moved into a 1920 Craftsman home in Mission Hills and began researching the family who built the house. He has since lived in several of San Diego’s old “trolley neighborhoods.”  Mr. Mengers has degrees in anthropology, archaeology, and history from University of California San Diego and San Diego State University. He is a Senior Archaeologist/Historian with Carlsbad-based environmental consulting firm PanGIS, Inc. and also serves on the Board of Directors of the San Diego County Archaeological Society.

The mission of the San Diego Archaeological Center is to preserve archaeological collections and promote their educational, scientific, and cultural use to benefit a diverse public. Visit
