The Teravista subdivision is
situated on highly expansive soils and, as a result, there has been
significant movement in the pavement over time due to changes in
moisture content of the pavement substructure. A result of this
condition is deflection or undulation of the pavement riding surface.
Williamson County Road & Bridge Division is undertaking a study to
determine the extent of the surface deformations. Surveying and Mapping,
Inc. (SAM, Inc.) will utilize their “Google maps”-type vehicle to
electronically survey and assess the pavement surface.
