Bison Pipeline

HRA conducted a cultural resources survey for the proposed Bison pipeline in North Dakota. HRA inventoried a 124-mile segment of the pipeline as well as 50 miles of reroutes and over 100 miles of access. HRA also managed complex Esri ArcGIS databases of GPS data that included survey areas and site information over the course of the three year project. These data were incorporated into a variety of map books that were developed to accommodate the quickly changing survey and site data.
