Over the River Survey (2010)

Intensive Inventory

The intensive inventory, commonly referred to as “Class III,” entails a systematic pedestrian survey of the project area, which is known as the Area of Potential Effect.

Evaluative Test Excavation

Test excavation is an extension of certain intensive Class III inventories.  Its sole purpose is to facilitate National Register evaluations, and it is carried out in cases where surface evidence alone is insufficient to permit the site evaluation process to go forward.

Mitigative Excavation

Mitigative excavation typically targets those portions of a site shown through test excavation to have the greatest data potential.  Comprehensive data analysis, artifact cataloguing, and technical report writing follow.
