Phase 1 North and South surveys and “soft digs” moving forward
To provide an undergrounding design that reduces the risk of conflicts with existing underground utilities, the Project Team is determining where existing utilities are located and survey that location. Industry experts call this process a Subsurface Utility Assessment (SUA). This is generally conducted using Ground Penetrating Radar (GPR) and a limited number of small excavations called “soft digs”. Currently, both the GPR investigation and the soft digs have been completed for Phase 1 North (Onondaga Avenue to the Inlet) with Phase 1 South (Sloan’s Curve south) to be completed within the next couple weeks. The photos below are of “soft digs” being completed in Town and were provided by Inframap, one of the undergrounding project team members.
