When a major sinkhole collapsed in the middle of a Round Rock neighborhood, taking a piece of Cambria Drive with it, Cambrian was chosen to provide comprehensive karst services for the Williamson County Engineer. Dr. White led the effort which included exploration and mapping of the cave, assisting with safety protocols, compliance and mitigation reporting to the TCEQ, collaborating with engineering consultants on the mitigation plan, providing construction inspection services, and responding to information requests from the County public information officer. The high-profile project was completed safely and successfully despite intense media attention in a high litigation-potential situation.
