The County's First Historic Resource Inventory

Permit and Resource Management Department Banner 750

Sonoma County’s first Inventory of historic resources began in fall 1972, when the Planning Department began coordinating with geography faculty and students at Sonoma State College to conduct a Historic Sites Inventory. The work expanded during the 1974-1975 academic year to include geography and history faculty and students.

The communities surveyed as part of the first Historic Sites Inventory were:

  • Glen Ellen and Kenwood
  • Bodega, Bloomfield, Valley Ford, and Two Rock
  • South Sonoma Valley
  • Cloverdale, Geyserville, Alexander Valley, and Dry Creek Road in Healdsburg
  • Petaluma

About 500 properties were surveyed on the first Inventory.
