Calhoun Preservation has inventoried and documented the current state of historic and non-historic buildings on a variety of scales, from a few blocks in downtown to massive districts covering thousands of buildings.  Some surveys have looked at geographical clusters of resources (such as a downtown commercial district or a residential neighborhood), while others studied resources linked by a common theme (such as theaters).  Surveys end up telling us more about our local history and how the architectural fabric reflects its change over time.
