What’s Next For This Project?   

Preliminary design has been prepared for the entire length of the Selected Alignment Alternative.  The Design Public Hearing and comment period provides the public an opportunity to view the preliminary design and provide input to the Department.  These comments, due by June 19, 2008, will be reviewed and addressed in this project’s Design Reassessment.  A Design Reassessment is prepared when minor revisions are developed between the proposed project and impacts as described in the FEIS and the proposed project developed during preliminary design.

Once comments are addressed and the Cultural Resources survey and final design plans are completed, right of way acquisition and the construction phases of the project can then proceed as funds become available. Some funding for the project is included in the Statewide Transportation Implementation Plan and will be available to begin right of way acquisition.  At this time, there is no construction schedule for the proposed Springdale Northern Bypass.

A Phase I Cultural Resources survey of the Selected Alignment Alternative is expected to begin this year.  Cultural Resources include a wide variety of site types ranging from historic (those resources that are at least 50 years old) structures such as houses, barns, bridges, rock walls, etc., to historic and prehistoric archeological sites.  This survey will be conducted to find any previously unidentified cultural resources within a corridor that extends approximately 1000 feet from the conceptual centerline of the Selected Alignment Alternative.  Local landowners will be contacted for permission to access their property by the archeological firm performing this work.  It would be beneficial to inform the archeologists of known historic or archeological sites in the area.   

The Phase I survey typically consists of visually inspecting the prospective right of way and using shovels to dig test holes on a grid spaced from 15 to 100 feet apart and approximately 12 inches wide by 16 inches deep.  The material from the test holes is examined for evidence of archeological sites and then the holes are backfilled.  The evaluation of any sites located will continue with a more intensive investigation during a future Phase II survey.
