Santa Cruz Island Geotechnical Drilling

Gregg Drilling, working for the National Parks Service and Kleinfelder, was asked to complete a number of geotechnical borings on Santa Cruz Island. The work provided a unique challenge as the island has no dock area to unload equipment.

Gregg was able to mobilize a truck mounted rotary drill rig on a National Parks Service barge for a beach landing and access to the site. Due to the historical buildings on the site, drilling activities had to be carefully situated as to leave any archeological areas un-touched. Gregg’s crew worked closely with the National Park Service archeological team and Native American representatives to ensure historical areas were preserved.

Over a two week period, Gregg completed five boreholes up to 150ft in depth with daily personnel transport from Ventura, CA
