antebellum measure

The capacity of a civic object, such as a city, road, or field to retain history. The passage of years in and of itself will cause deterioration and therefore a lost of historic authenticity unless the civic object has been preserved via a sudden event such as a sand storm, volcanic eruption, sudden inundation by the sea, complete and sudden migration or death of the occupants of the civic object. The damage of the event will lower baseline value, but the measure in this case will be 0. At the high end of the measure are highly urbanized environments where it is the practice to clear the land and rebuild rather than build over the rubble of previous cities. This is a measure of 10.
