The State Historic Preservation Office (SHPO) creates the framework for the inventory process in Oregon. These guidelines are regularly updated; therefore cities may have a collection of different inventory forms that include slightly different or, in some cases, more detailed information. These forms are cumulative in nature; a new form does not overtake an older form. Together, they paint a picture of the evolution of the building, and depending, upon the type of inventory form used, different information will be presented. If a structure is designated, the inventory form provides background about what features made it suitable for designation and can be updated as needed or required. An omission or incorrect detail in an inventory form does not bind the city to a certain outcome as a land use action might. Rather, they are informative and provide relevant context to future land use decisions.
The electronic version of the SHPO Survey Guidelines can be found on the Oregon SHPO Inventory Guidelines page.
If you believe that a form has incorrect information, please email Christina Robertson-Gardiner, Preservation Planner, or call 503.496.1564. Depending upon the information presented, the forms might be updated, or a note may be added to the website.
If you own the photo or have the authority to use it, Oregon City would love to add it to its ongoing collection of historic photos. We can even add it directly to the inventory page for the building. Photos from the Oregon Historical Society, Museum of the Oregon Territory, or organizations with propriety ownership will not be uploaded. Email Christina Robertson-Gardiner, Preservation Planner, or call 503-496-1564 for help in uploading or scanning your photo.
An inventory form can be created for any building. Oregon City currently has inventory forms for both historic and non-historic buildings. Historic designation is bestowed on a property that has applied for local designation through the Land Use process. Oregon City has over 500 properties locally designated! When properties are locally designated, the city has review authority for exterior alterations to the site. Interior alterations do not require a historic review.
Buildings listed on the National Register of Historic Places are usually locally designated as well. National Register designations are separately processed through the Oregon State Historic Preservation Office (SHPO) and the National Park Service (NPS).
