Chrysalis Archaeology joined the design team in 2009 to undertake all archaeological tasks associated with the City Hall Rehabilitation Project. The Project was designed to upgrade the 200 year old City Hall Building and surrounding area. During the course of this multi-year project, 42 features were documented and over 40,000 artifacts, faunal remains, and human remains were recovered. All of the findings were considered highly significant, and the individual features which included large cisterns, wells, and an early nineteenth century midden, would constitute National Register Eligibility.
