The Secretary of the Interior's Standards for the Treatment of Historic Properties lists four treatment approaches:
~ Preservation places a high premium on the retention of all historic materials through conservation, maintenance, and repair.
~ Rehabilitation emphasizes the retention and repair of historic materials, but more latitude is provided for replacement of the materials.
~ Restoration focuses on the retention of materials from the most significant time in the building's history, while permitting the removal of materials from other periods.
~Reconstruction establishes limited opportunities to re-create a non-surviving building or site.
~ Evaluating the Historic Character / Significance of the building or site.
~ Researching the historic background of the building or site.
~ Developing Historic Structure Assessment (HAS) Reports to document the physical condition of the building or site.
~ Develop proposed use of the restored building or site.
~ Developing Preservation and Maintenance Plans.
~ Maintain mandated code requirements.
~ Utilize representative National Park Preservation Briefs.
~Identifying and gathering data on a community's historic resources.
* Due to the growing recognition, by citizens and governments at all levels, that such resources have value and should be retained as functional parts of modern life.
~ Planning and background research.
Undertake field survey, organization, evaluation, and presentation of survey data.
* Assist in the completion of the Architectural Inventory Form.
~Organized compilation of information on those properties that are evaluated as significant.
