Janus Research assisted the FDOT with the development of the District Six Cultural Resource Identification tool, the prototype for the Environmental Screening Tool (EST). Following this success, Janus key personnel served on the FDOT ETDM Task Force, which included representatives from FDOT, MPOs, the State Historic Preservation Office, the ETDM technical team, and the Seminole Tribe of Florida. We evaluated the existing GIS data sets in the Florida Geographic Data Library (FGDL) at GEOPlan, made specific recommendations to enhance the EST, identified other strategic data layers, and developed guidelines for ETAT members making cultural resource evaluations. Janus also developed the criteria used to assign degree of effect, and evaluated local data for integration into the EST. The resultant white paper, Accomplishing Cultural Resource Evaluations within the ETDM Process, served and continues to serve as the foundation for cultural resource reviews.
