This paragraph does not necessarily require a recipient to make each of its existing historic properties or every part of an historic property accessible to and usable by handicapped persons. Methods of achieving accessibility include:
Because the primary benefit of an Historic Preservation Program is the experience of the historic property itself, in taking steps to achieve accessibility, recipients shall give priority to those means which make the historic property, or portions thereof, physically accessible to handicapped individuals.
The Administrator shall periodically review any waiver granted under this section and may withdraw it if technological advances or other changes so warrant.
