Even with the expert engineering promised by The Cliffs Communities, Inc., roads built on these soils are subject to failure. These undisclosed soil assessments should be a concern to the members of The Cliffs at High Carolina Homeowners' Association, Inc. as they will be assuming responsibility for all High Carolina private roads.

For an example of property owners' costs to repair and remediate landslide damaged private roads please see the Horseshoe Cove Landslide Report.
