A historic context statement is a narrative history of a specific theme, topic, or place that provides a framework for evaluating a property’s historic significance. The City has developed a number of historic context statements related to early settlements and historical themes that represent historic properties in Orange.

• City of Orange
• Cypress Street Barrio
• Eichler Tracts
• El Modena

The historic context statements were prepared by historic preservation consultant Chattel, Inc. as part of the 2010 General Plan Update.
