BACKGROUND RESEARCH The background research will include relevant land-use data from the Orange County Register of Deeds and an examination of historic maps of Hillsborough. Background research may also include contacting historical researchers who have special knowledge of the area. The purpose of the background research is to compile sufficient and appropriate information to understand the context of any cultural resources identified during the project. B. FIELD INVESTIGATIONS Fieldwork will consist of exploratory excavation units in the vicinity of the proposed well fields planned for the Public Market House and Riverwalk Park areas. The number of exploratory tests will be determined in the field and will be based on the results of subsurface testing. The excavations will be sufficient to determine whether intact deposits of cultural material that meet the definition of an archaeological site are present in the Public Market House and Riverwalk Park areas. Archaeological sites are defined as locations that provide physical evidence of a sufficient quantity and association to suggest that information about past human behavior is present. Given the uncertainty as to 1)the depth of fill material that was brought to the area in 2007 during the construction of the Public Market House and 2)the degree of compaction that was used to stabilize the Public Market House parking areas, it is estimated that the field investigations will take 4 days. If the field investigations reveal that hand-excavation is not feasible, then Orange County will be notified as soon as possible in order to determine an alternate approach and modification to the scope of work. 4
