Survey Historic Places

Surveys of historic resources are important to the citizens of Oregon because they help us identify significant buildings, structures, objects, sites, and districts, and focus our limited resources on their preservation.

Mandated by the National Historic Preservation Act (NHPA) of 1966, and Amendments, surveys are carried out and supported by the State Historic Preservation Office (SHPO), as well as by historic preservation professionals on contract to other state agencies, local governments, and businesses.

A survey is the process of gathering and recording information about historic resources, identifying those that may be historically significant locally, statewide, or nationally, and updating existing information on previously documented or officially designated properties. Once recorded, the data generated are added to the statewide inventory maintained by the SHPO and on city or county inventories maintained by local jurisdictions. Conducting surveys and creating an inventory of resources are usually the first steps leading to local recognition and preservation of those resources most important to our state and local heritage.

Oregon Sites Related to Women's History

2020 is the 100th anniversary of women's suffrage in the United States. We are joining in with Oregon 2020 to commemorate the event by collecting information on places associated with women in Oregon History. These may be residences, business places, social gathering spaces, sites for suffrage and women's rights efforts, burial sites, campuses, etc.

Please provide any and all information and documentation you can by visiting The information will be added to the Oregon Historic Sites Database and may be used to designate properties to the National Register of Historic Places in the future. For information about what to submit, contact Jason Allen at 503-986-0579.
