El Cajon City Hall is located at 200 Civic Center Way, El Cajon, CA 92020.
El Cajon was incorporated in 1912. The Spanish term "el cajon" meaning "the box" is descriptive of the physical setting of the area which is a broad, level valley surrounded by hills rising 200 to 600 feet above the valley floor. The city limits of El Cajon encompass a major part of the valley floor which had served, in the days of Mission San Diego de Alcala, as a natural enclosure for livestock grazing and more recently had served as rich agricultural land. Still undergoing rapid urbanization, the area is in the eastern portion of nearly continuous and undifferentiated urban growth radiating outward from the City of San Diego. El Cajon is decidedly suburban to San Diego.
