Live Oak Ranch
Also known as: Hagemann House
Why it's listed
Set on about 7.3 acres in the middle of Santa Cruz, Live Oak Ranch is a Victorian farmhouse complex reached by a quarter-mile driveway lined with cypress and eucalyptus. The original farmhouse went up in 1871 and was remodeled in 1885 by architect Emil John, who gave it twin towers, turned woodwork, stained glass, iron grillwork and a picket fence. Frederick Hagemann, a German-born immigrant, built the house for his wife; his ranch once covered 110 acres of wheat, cattle and other livestock. A barn more than 100 years old and other outbuildings survive. The grounds hold old oaks, a creekway with wild azalea, and habitat for quail, doves and waterfowl. The nomination presents it as an unusual small-scale Victorian property that kept its rural garden setting as the city grew around it, and it stressed preserving the whole setting against a planned road extension that would have cut through the grounds.
Significance in brief: The nomination names architecture and conservation as the principal areas of significance. It argues the house is a rare Victorian dwelling that still sits in a rural, garden setting within a city, on a site of more than 7 acres. The grounds also shelter wildlife, and the property was then threatened by a proposed road extension.
