Historic American Landscape Survey (HALS)

HALS is part of the largest cultural resource documentation program – all of which is accessible online.  This session is intended to be advanced but will be useful to those who know little or nothing about HALS.  Hear about the past, present and future of HALS and learn the three components of HALS documentation and the difference between the standard and short formats.  The session will emphasize how HALS can be used as a mitigation tool to comply with NEPA Section 106 and in other ways.  Also, what distinguishes HALS from other documentation programs like CLRS, DPR 523 forms, and National Register nominations.  While it will feature resources in California, the information and application can be applied nationally.
