A Railroad Runs Through It: Historical-Period Ethnic Chinese and Mexican Communities in Downtown Redlands, California

Statistical Research, Inc. (SRI) conducted archaeological excavations in 2019 and 2020 in support of the development of four parcels at the northern edge of the historical-period Chinatown location in downtown Redlands. SRI’s work identified not only evidence of Chinatown, but also of a previously (archaeologically) unstudied ethnic Mexican community in the project area. This presentation focuses on household consumption and community structure among both groups from the later nineteenth century through the middle of the twentieth century.

Dr. Grenda is an archaeologist with experience in both prehistoric and historical archaeology. He is the president of Statistical Research, Inc., an archaeological and historical consulting firm with offices throughout the western United States. He has a doctorate in anthropology with a specialization in prehistoric archaeology from the University of Arizona, a master’s degree in anthropology with a specialization in historical archaeology from the College of William and Mary, and undergraduate degrees in economics and anthropology from the University of Redlands.


He was appointed to the California State Historical Resources Commission in 2005 and served as a commissioner until 2013. He is currently the Chair of the Government Affairs Committee of the Society for American Archaeology (2014-2020) and a member of the board of directors of Leaders in Energy and Preservation. He is also active at the local level as the vice president of the Redlands Conservancy.


Dr. Grenda’s research interests include California prehistory, historical archaeology, prehistoric economies, and archaeological method and theory. He has published numerous books and articles and has taught archaeology at the University of Redlands and California State University, San Bernardino.
