Are we prepared for an earthquake?
Beaufort County building Codes has a permitting and inspection process that ensures structures in Beaufort county are as earthquake resistant as possible. Also, during roadway and bridge construction, County engineers make sure our infrastructure is built as soundly as possible in order to withstand earthquakes and other disasters. Sometimes, the soil must be equipped to prevent liquidation which would result in the collapse of highways and bridges.
