 When we evaluate a property, the first thing we evaluate is, is it significant? Does it meet one of our national register criteria? The next step is to evaluate its historic integrity. Historic integrity is defined as those physical characteristics that are tangibly related to the importance of that historic property. There are seven aspects of integrity that we evaluate properties under. Location, setting, design, workmanship, materials, association, and feeling. Those seven aspects of integrity are all important, but they are weighted depending on why a property is important. So a property that is significant under criterion C for its architecture, for its distinctive characteristics of a period or type of property, or of the work of a master, or of high artistic value. Integrity of design is paramount. Integrity of workmanship is important. Integrity of materials is essential. Integrity of location may be compromised. A moved property that is a significant example of a pratt through truss bridge can still be a significant example of a pratt through truss bridge if it has been relocated. However, if you're going to nominate a property for its association with events, criterion A, location is of utmost importance because that's where the event took place. The feeling that the property engenders in you is important. Does this look right? Do I get that sense of time and place is important? The design may not be as important. What would be important is those aspects of design that help define the event. Interior spaces should be reflective of that period when that event occurred. But the fact that the building itself may have been altered over time is of less importance. We weigh the integrity of design or workmanship less than we would location, setting, and feeling in association.
