North Charleston, SC: what's different here
North Charleston is located in Charleston County, South Carolina. The area features a humid subtropical climate, which can increase seasonal irrigation use and backflow-device testing needs.

North Charleston is approximately 6 miles and 10 minutes from Charleston via main highway.
